Background Facts

Dr. R was a restorative dentist practicing in a rural town in the American mountains, with only 2 other dentists within a 30-minute drive, and no dentists with sophisticated restorative capabilities closer than nearly 4 hours. A 51-year-old healthy woman, B, presented to Dr. R, having recently moved into the area. Her dental history was complex, due primarily to her having suffered significant facial trauma some years ago in a motor vehicle accident, which led to the loss of 6 maxillary teeth. She had been restored from that time with various removable upper partial dentures, but she remained unhappy with her appearance and her ability to function. Luckily, her mandibular teeth were essentially unharmed in the accident, so the lower jaw had a full complement of teeth, other than 2 third molars which were extracted as a young adult and a second molar that vertically fractured after root canal therapy, necessitating its removal.

She sought Dr. R’s opinion as to whether she could have a fixed prosthesis for her upper. After evaluating her clinically and radiographically, Dr. R took alginate impressions and a basic bite, which were poured up and mounted while B left for a short lunch before returning. Dr. R determined that she was a good candidate for implants, upon which a full-arch restoration could be fabricated. B immediately rejected the idea of implants after seeing her brother have what she described as an “awful experience” with implants, so she asked Dr. R for another option. He suggested a 13-unit maxillary “roundhouse” bridge, which would involve the preparation for abutments of all remaining upper teeth, and joining them with pontics which would cover the spaces left by the missing teeth. He explained that, after the teeth were prepared, which he planned to do on one long visit, he would place a temporary bridge, which would remain in place while the remaining steps of bridge fabrication – impressions, bite registration, and laboratory creation of the final prosthesis, followed by potentially several try-in visits to idealize the occlusion – were completed. B liked the concept and wanted to proceed.

Dr. R asked his office manager to meet with B that same day, to go over the fees and set up a payment schedule. The total fee quoted was $30,000, which accounted for everything, regardless of how many adjustments were necessary after insertion. The manager presented B with a “financial agreement”, which set forth the total fee and the payment schedule, which required 3 equal payments at the times of tooth preparation, final impressions, and cementation. The agreement noted, in bold lettering, that B understood that Dr. R would absolutely not proceed with subsequent steps until payments were up-to-date all along the way. B and the manager thoroughly discussed all aspects of the agreement, and B signed the form. Before leaving, she scheduled the first appointment.

Approximately 2 weeks later, B presented to the office and handed a check for $10,000 to the front desk. Dr. R treated B for an entire afternoon, during which time he prepared all of the maxillary teeth and placed a laboratory-processed provisional, which he relined before temporarily cementing it. On her way out, B scheduled her next visit for close to a month later.

At that following visit, she again provided the staff with a second $10,000 check, before spending most of the morning with Dr. R, as he fine-tuned the preparations, completed final impression making, and adjusted and temporarily recemented the provisional appliance once again. He asked B to wait for the office to contact her before next coming in, so that he would be certain that the lab would have adequate time to fabricate the final product. Several weeks later, the office called B and left a voicemail which advised her that she could set up an appointment for insertion. B did not respond, so the office manager repeated the process of calling.

Days later, B called the office, very upset, and asked to speak directly with Dr. R. She tearfully told Dr. R that her husband had lost his job, so she could not afford to make the final $10,000 payment, and she did not anticipate being able to do so in the near future because of a tight job market in her husband’s industry. Dr. R firmly, but professionally, reiterated his policy of taking no further steps until all payments due were made. He encouraged her to return with payment as soon as possible so that he could complete the work.

As of almost 7 months after the laboratory had fabricated the bridge, B’s husband was still out of work, and her temporary bridge was beginning to crack, thereby making eating difficult for her. She called the office manager, asking to be seen to have a new temporary bridge placed, or at least to have the current one repaired, but was told that no further treatment would be provided to her without further payment. When coincidentally speaking with an attorney cousin of hers by phone, she explained the dental situation, her deteriorating mouth, and Dr. R’s refusal to finish the treatment he had started, or even render emergency care. The cousin was outraged by Dr. R’s position, and offered some solutions, including that she speak with a malpractice attorney for advice; but in the interim, he suggested that she drive to a medical center a good distance away, which had a dental clinic that would hopefully repair the temporary for an inexpensive sum.

B followed her cousin’s advice and was able to have the needed repairs at an affordable price. She also spoke to a malpractice attorney, who contacted a dentist friend to get a sense of whether B had an actionable case. In the end, B was told that Dr. R had not seemingly performed any actual treatment which departed from the standard of care, but that he had abandoned her by being unwilling to complete the midstream treatment, and by being unwilling to even perform emergency repairs to maintain her mouth in a healthy state as a stopgap measure. By this time, B was extremely angry with Dr. R, so she wanted to act in any way she could against Dr. R; the only way, according to the malpractice attorney, was to file a complaint with the state’s dental board, explaining the situation in detail and seeking that Dr. R be penalized in some way.

Once B’s husband became employed again and their other outstanding bills were resolved, B was in a position to pay for the completion of her work, now a year-and-a-half after she last saw Dr. R. But she refused to go back to Dr. R because she felt betrayed by him and because her board complaint was ongoing, so she found the closest restorative dentist to her – still quite a distance away – who was willing to pick up the in-progress treatment and complete the roundhouse for less money than B would have paid Dr. R. She ended up very happy with her new bridge, although it took much longer than anticipated and with more stress than expected.

Board Actions

A board investigator interviewed B to get all details she had to offer, and also gathered all of Dr. R’s records, radiographs, billing statements, phone memos, lab prescriptions and receipts, and the financial agreement along with the attached notes of the office manager. Once all of this evidence was reviewed by board members, an interview with Dr. R was scheduled.

Dr. R appeared for his interview with an attorney retained by his malpractice carrier, as was provided for under the terms of policy. Dr. R did not dispute what had been said by B [and as is described in this case study], but instead held firm to his position that he had entered into a financial contract with his patient, which she was unable to fulfill monetarily, so he felt that he was under no obligation to provide any work for which he was not paid, regardless of the stage of treatment.

Board members deliberated as to how to resolve the complaint of B, and they then levied severe sanctions against Dr. R, with detailed explanations to go along. Dr. R was fined heavily, given a 2-year suspension of which all but 4 months were stayed, and mandated to take 8 hours of coursework on the subject of professional ethics.

The board’s explanations clearly set forth the rationale behind the actions. Dr. R was obligated not to leave his patient in an unstable dental state once he began treatment, regardless of financial agreements or her inability to pay as treatment progressed; doing so, determined the board, constituted an abandonment of B, subjecting her to potential bodily harm as a result, and violating his professional duty of non-malfeasance (“do no harm”). The board found Dr. R’s unwillingness to perform even basic repairs on the provisional was an aggravating factor which raised the severity of the sanctions. And the board pointed to the fact that Dr. R was the only dentist in the area and its reasonably close surroundings to be able to handle a case of this type, so his refusal to continue treatment placed a burden on B which was greater than had there been other local dentists able to competently treat her.

Finally, the board explained, for the apparent purpose of education, that Dr. R would have been well within his rights to have refused to treat B from the start if he believed that he was incapable of performing appropriate treatment on her, if she had insisted upon having treatment performed which Dr. R had believed to be inappropriate, if he felt that she would not be an adequately compliant patient, if she had acted personally inappropriately toward him or his staff, or if she was unwilling to pay the fee he requested; but once he accepted B as a patient, and began treatment, he placed himself into a position of unbending ethical obligations toward her which overrode all other considerations.

Takeaways

Dentists are professionals, whose “customers” are patients, and who, consequently, are entitled to have ethical standards upheld in all circumstances. When those ethics are violated by the dentist, they are subject to severe sanctions, up to the possible loss of license. These principles should be viewed entirely differently from departures from the standards of care of treatment – mistakes in performance or errors in judgment – which might cause physical injury. The difference can be viewed as a matter of intent and professionalism: Dr. R fully intended to take the unprofessional actions/inactions that he did, and that is what led to the severity of what the board meted out.

Dentists do well to realize that any situation which prevents them from being able to complete work that has begun puts them at risk for a claim of abandonment, with the penalties that carries if demonstrated. So, any time that they leave the employ of an office, or any time they wish to dismiss a patient for any of a variety of reasons, deep consideration as to how the impacted patients will be affected must take place, with plans put in place to protect those patients. Even if patients are terminated without ongoing work in progress, they should be told of their conditions in detail, advised that they ought to seek dental care elsewhere as soon as is practicable, and be provided with emergency care by the terminating dentist for a reasonable period of time.

Dental malpractice claims are resolved by money, which is usually paid by a malpractice insurance carrier, but abandonment claims leave the dentist holding the whole bag, exactly as they have done to their abandoned patient.

Background facts

For Dr. A, extracting teeth was an everyday part of practice, as was virtually the entire scope of dentistry. In addition to postdoctoral training, she had been performing these procedures for years in a region of the state with no oral surgeons within a 2–3-hour drive. She was a participating provider in several dental insurance plans that were popular among her patients.

One such patient, P, was an 18-year-old high school senior who presented for an annual recall visit, with a new complaint of periodic pain associated with the lower right third molar. Despite P being of majority, his mother accompanied him into the treatment room to see Dr. A. Following a clinical examination, a panoramic film was taken and viewed by Dr. A. Tooth #32 was erupted, had incomplete apex formation, but was still in close radiographic proximity to the inferior alveolar canal. Dr. A assessed the pain to be a function of difficulty in cleansing the area, with inflamed gingivae as a result. She suggested, while pointing to the panoramic, extraction, which she said, "shouldn't be too hard,” although it carried a "slight risk of a nerve injury which could leave P's lower lip and chin numb, and rarely be permanent." This conversation was documented with specificity in the chart. P had heard about impacted wisdom teeth from a few friends, so he asked whether his tooth was impacted. Dr. A replied, "No, it is not.” P wanted to think about it, so he left the office with a sample of an oral rinse and instructions as to how to improve his oral hygiene. A month later, the symptoms persisted, so P's mother called the office to schedule an extraction appointment.

Before having local anesthetic injected, P was handed a paper entitled "consent form,” which he and his mother "briefly read.” The document contained a list of potential risks, including a general statement about possible "loss of sensation.” P signed the document prior to the extraction going forward. Dr. A worked on the tooth for well over an hour, much longer than she had anticipated, cutting out pieces of tooth and trimming away bone using round and fissure burs. P could taste blood, particularly at one point, which caused Dr. A to pack gauze in his mouth. The following day, P awoke to find the right half of his lower lip and chin numb, which he did not find surprising, given the warning beforehand, but so was the right half of his tongue, which was a surprise. At post-op visits, Dr. A assured and re-assured P and his mother that feeling would return to normal — it never did.

Separately, P received a bill for Dr. A's services from her billing office, seeking a co-pay for "#32 7240.” The amount was significant, despite Dr. A's advertised plan participation, so P's mother questioned the office manager as to what all of this meant. The response was that, according to the insurance plan's rules, Dr. A was permitted to charge that amount for fully impacted wisdom teeth, as this was. P's mother replied that Dr. A had specifically advised her and her son that the tooth was not impacted, no less fully so. The office manager spoke with Dr. A, but the answer came back that, because Dr. A had to work so long to remove the tooth, she was not willing to make any adjustments.

P's mother contacted the insurance carrier to explain the situation. The carrier requested a pre-treatment radiograph from Dr. A, based upon which the in-house reviewers concluded that the tooth was not appropriately coded as 7240, but rather should have been 7210 (surgical extraction of erupted tooth). Under the plan provisions, Dr. A was therefore not permitted to charge any co-pay but instead accept the plan payment in full. When the insurer notified Dr. A of that, with a copy sent to P's mother (whose employer provided the coverage), Dr. A was steadfast that she was entitled to the amount billed and would send P to collection if she was not paid. P's mother did pay the claimed balance, but the carrier dropped Dr. A from the panel due to what it referenced as "upcoding resulting in excessive billing.”

Legal action

P had slowly been adapting to the lip, chin, and tongue numbness, but his mother remained upset about the principle of billing her son and threatening a collection action, so she contacted an attorney. The attorney was not very familiar with dentistry in any legal regard, so he reached out to his own dentist, with a copy of Dr. A's records that he had been provided, to help him interpret what was going on. The dentist agreed with the insurance company's position that the extraction had been inappropriately upcoded, but perhaps more importantly that it was clear from the records that, while P had been warned of the possibility of an inferior alveolar nerve injury and its effects, he had not been told anything about tongue numbness, which came from an injury to an entirely different nerve branch and which should have been avoided if proper technique had been employed.

The attorney initiated a lawsuit against Dr. A, asserting lack of informed consent relating to the lingual nerve injury, dental malpractice regarding the causing of the lingual nerve injury, and breach of contract leading to the improperly billed (and collected) co-pay amount. The defense attorneys assigned to Dr. A by her malpractice carrier reviewed the case with their client and advised her that they would seek expert opinion as to the substance of the informed consent and malpractice claims, but that she would not be covered for the breach of contract claim, per a clearly stated policy exclusion.

The expert retained by Dr. A's counsel was provisionally willing to present a defense as to the malpractice claim regarding her having negligently caused the tongue numbness, but that position would need to be re-evaluated following her deposition testimony. However, there was no evidence in the record to demonstrate that she had provided any warning of a potential lingual nerve injury and its impacts. The defense expert did not see a pathway to successfully defend the claim of lack of informed consent. A second expert reviewer reached the same conclusion.

Dr. A's attorneys had a candid discussion with her. Even if the malpractice claim could likely be effectively defended, the lack of informed consent claim could not. So, P would be entitled to a monetary award regardless of which, or both, of the claims went P's way in the eyes of a jury. Dr. A agreed to have her attorneys seek to settle the claim, to be paid by the malpractice carrier, which they did. As part of the settlement agreement, Dr. A would personally return to P the amount his mother paid her for the co-pay.

Takeaways

While it is impossible to know whether P would have sought an attorney at some point to file an action on his behalf based upon the substantive dental issues, it is quite clear that the issue which drove the initial attorney involvement was the billed, and eventually paid, co-pay amount. There is then perhaps a bit of irony that the money that Dr. A was unwilling to waive directly led to a settled malpractice claim, but that insisted-upon co-pay not only started the legal action steps but was also ultimately paid by Dr. A out-of-pocket. Dr. A made the decision to demand a disputed amount of money, and that decision likely cost her far more — particularly with her being dropped from a panel — than had she acquiesced in the first place. It is not our role here to advise dentists as to whether they should fervently go after unpaid, disputed fees. Instead, we demonstrate a situation where doing so ended up causing more harm than benefit. Food for thought.

Experience teaches that lay jurors might not always understand scientific, dental facts, sometimes making their determinations counter to what experts and attorneys anticipate. On the other hand, issues relating to overbilling or upcoding are relatively straightforward for plaintiffs' attorneys to explain to jurors, and simple for them to understand. At times, jurors might put all else aside and render a verdict for a plaintiff if they do not see the defendant-dentist as having been honest. Such is a version of jury nullification, with the jury members substituting what they deem critical in place of what the law says is critical. Taking subjectivity of that type out of the hands of juries increases a defendant's chances for success.

This case study exemplifies how the trigger for a patient seeking legal counsel might have nothing at all to do with the quality of dentistry. Yes, dentistry is complex, and there is an ever-present unpredictability factor, so ideal results do not happen with every procedure, with every patient. What need not be complex are matters over which dentists and their staff members have full control — such matters can virtually always be taken out of the equation as to what starts the legal ball rolling.

Finally, we briefly address the coding of procedures for billing purposes. The ADA and perhaps other associations provide numerical codes for dental procedures, which state the procedure performed and which often serve as the basis for which payment is sought and made. With few exceptions — such as 7241 for full impactions with unusual surgical complications, or time under sedation/general anesthesia, as examples — procedure codes do not take into account the length of time required to complete or the difficulty in doing so. To upcode to a procedure not actually performed, for a higher fee, is to invite a host of problems, including the initiation of a malpractice lawsuit or Dental Board complaint.

Summary of takeaways

A signed consent form alone is not enough — patients should also be verbally informed of all risks, benefits and alternatives associated with a procedure, by way of back and forth conversations, and those discussions should be thoroughly documented.
Billing disputes and inaccurate procedure coding can damage patient trust and may become the catalyst for malpractice claims.
Upcoding procedures can result in payer disputes, loss of network participation, regulatory concerns, and increased legal exposure.

Underlying facts

K was a 47-year-old man, who has been an asthmatic for all of his life. His medication regimen has changed over the years — to include, at times, corticosteroids, biologics, and rescue inhalers. At the time of his subject series of visits with Dr. F, K's long-time general dentist, he reported taking daily steroids and an occasional need for the inhaler, with asthmatic flare-ups not uncommon. K had skipped seeing any dentist for some time, so Dr. F found 3 carious lesions in the left posterior for which endodontic care was indicated, and he advised his patient of exactly that.

For some reason, K explained, he had developed a fear of dentistry, the reason he had stayed away, and the prospect of root canal therapy, in 3 teeth, was daunting. Dr. F told his patient that, while he does not often do so, he would prescribe an oral sedative to be taken shortly before each of the 3 procedures, as an adjunct to nitrous oxide/oxygen ("laughing gas") given through a nasal hood. K agreed to try that approach, and filled the prescription given to him.

Just before being driven to the dental office on a relatively humid day by his young adult daughter, K took 2 of the tablets — rather than one, as prescribed — and arrived in a surprisingly relaxed state. When Dr. F peeked into the waiting room, he asked "did you take the medication?" "Yes I did." K was soon seated by Dr. F's assistant, who placed the hood and dialed in N2O/O2 at 5 liters per minute and a 70%/30% ratio, all of which was Dr. F's custom.

When Dr. F entered the treatment room, he briefly made small talk with K before delivering a mandibular block and infiltration. K winced and became visibly upset, which led to his beginning to show difficulty in air exchange. Dr. F asked the assistant for a pulse oximeter, but it could not be located. Dr. F switched the gas flow to 100% oxygen, but he had no means of delivering it with positive pressure. K deteriorated, with his lips becoming bluish, and his respiratory efforts becoming more and more futile. The receptionist heard the commotion, came to see what was happening, and called 911; EMS came 17 minutes later, by which time K was breathing poorly and minimally conscious. With telephone instructions from an emergency department physician, a paramedic started an IV line and injected a muscle relaxant while an EMT squeezed oxygen through an Ambu bag, slowly raising the O2 saturation from 73% to 92%.

K was transported to the hospital, where he was admitted for 4 days, undergoing a complete pulmonology work-up and medication regimen modification. K was left with large ambulance and hospital bills, for which no health insurance was in place, owing to his being new to his current job, which he could not attend for another 2 weeks, unpaid.

Legal steps taken

Intimidated by the amount of money he owed, K sought legal advice, and was counseled that suing Dr. F might cover his expenses and lost earnings, as well as money to compensate him for his physical and emotional injuries. The newly retained attorney obtained copies of the records from Dr. F, the ambulance, and the hospital, and sent them to dental and internal medicine experts for their input. The dental expert knew that dentists in that State were required to obtain a permit for providing sedation at any level, including orally, with predicates to obtaining the permit being (1) an office assessment by 2 dentists from the State Dental Board, to assure that resuscitation equipment and drugs were available and functional, as well as (2) basic life support certification for the dentist and at least 1 present staff member (or ACLS for the dentist for deeper levels of sedation), and (3) doctoral or post-doctoral training in sedation techniques. Dr. F was not aware of any of these requirements, so, as the dental expert found on publicly available platforms, Dr. F had never applied for a permit; in fact, neither he nor any staff member was current with BLS certification.

In addition to filing a dental malpractice lawsuit against Dr. F, K, with his lawyer's help, filed a Dental Board complaint. In his response to the complaint, one of the arguments posed by the attorneys provided to Dr. F by his malpractice insurer was that Dr. F had not intended to do more than simply "take the edge off,” and it was K's own action, by taking a higher medication dose than prescribed, that led to a deeper level of sedation and the apparent laryngospasm that flowed from that. The Board was unmoved: the statute set out strict requirements, for any level of sedation, with the dose provided by Dr. F falling into that category; Dr. F had violated that statute. The Board levied monetary sanctions and a stayed 6-month suspension from practice.

The Board's findings and actions, which would likely make their way to a trial jury in that jurisdiction, made the malpractice defense a steep uphill battle. A settlement followed, compensating K for both economic (medical costs, lost income) and non-economic ("pain and suffering") damages.

Takeaways

The old adage that "ignorance of the law is no excuse" clearly applies here. While dentists are not expected to have the degree of understanding of laws that lawyers do, they are expected to know and abide by the parameters of their State's Dental Practice Act; there is simply no getting around that. With this is mind, had the case proceeded to trial, it is foreseeable to believe that a legal principle known as negligence per se would have come into play: in basic terms, when a person violates a statute which is intended to protect the public safety, and that violation causes an injury, there is essentially a presumption of negligence/malpractice. Here, Dr. F's failure to obtain the needed permit is quite readily argued to have caused K's injuries, based upon the facts that his training was inadequate and his resuscitative inventory was lacking, leading directly to the inability to protect K's safety. Legally, negligence per se provides what amounts to a short cut for plaintiffs, yet one which is avoidable.

Readers might wonder whether K's own improper action, namely taking twice the prescribed dose, could have alleviated Dr. F's liability, or at least a portion of it. The answer is maybe. When a settlement is made, as it was here, all of the potential legal arguments go away. But if the litigation had proceeded, and depending upon the State and locality involved, a jury might have been able to consider K's impropriety and reduce, or even possibly eliminate, Dr. F's liability. Taking that approach at trial is viewed by some lawyers as risky because jurors might see it as trying to blame the victim; but that does not mean that such a tactic does not ever occur, because it most certainly does. It ends up as a judgment call on trial strategy, left for lawyers to discuss with their clients, with a typical risk-benefit analysis playing a major role.

An issue underlying the facts in this case is the existing medical condition of K, as of the time of the procedure. He was a known, disclosed asthmatic, whose various medication regimens signaled a significant level of disease. Most practitioners would likely agree that such patients pose a higher risk profile when it comes to sedation, to any degree, such that a host of factors need to be considered beyond the "usual.” In terms of strict ASA classification, K would be viewed — based solely on his asthma condition — as a Class II (if the asthma was judged to be well controlled with management of it on an as-needed basis) or Class III (if the asthma was viewed as not being well controlled, with frequent episodes and constant treatment required) patient. Of course, there is subjectivity involved with assigning patients into these groups, but objective assessments ought to be used to guide the conclusion.

Finally, we address a defense that Dr. F raised with the Board, namely the level of sedation that was intended for K, rather than the one achieved. In some States, that difference might be determinative, but in the State of Dr. F's practice, that difference was irrelevant. Either way, it is a universal given that dose X of drug Y will necessarily produce different sedative results in different patients, even if nominally but potentially largely so; dentists are prudent to realize that sedative end points are unpredictable, that patients might become more deeply sedated than intended, that patients might have side effects generally associated with the deeper level, and that the dentist must be appropriately trained and otherwise prepared to handle even low likelihood, but severe, risk manifestations. There is often little room for error when a patient's state of consciousness is altered.

Summary of takeaways

Dentists are expected to know and follow their state’s sedation requirements.
Patient-specific risk factors can increase sedation-related liability.
Sedation outcomes can be unpredictable, so emergency readiness is essential.

Background facts

E, a 64-year-old man who was markedly obese with type II diabetes and atrial fibrillation, presented for the insertion visit of a PFM crown on his upper right second molar, tooth #2. Getting to that point had been far from easy for both E and Dr. M, owing to limited opening ability and an excess of facial soft tissue. Preparation for the crown and impressioning had each taken a full visit for the very same reasons. Suffice it to say, as Dr. M later did, there was very little room to work in E's mouth. No local anesthesia was given for this visit; as Dr. M placed the crown for what would be the final try-in, his finger incidentally made contact with E's soft palate, causing him to gag and unexpectedly move forcefully, which then caused the crown to slip out of Dr. M's wet gloved hand, and out of sight. Dr. M, an experienced practitioner nearing the end of his career, who liked to work "solo", called an assistant into the room to suction the oropharynx of the supine patient, with the hope of finding the crown tucked into a tissue fold. The crown was not found.

Dr. M explained that he would need to take another impression because the crown had "slipped behind the mouth"; he did just that over the next hour. As E was being dismissed, Dr. M said that the crown will work its way down the intestines, to be voided in the stool: E should inspect his stool over the following few days, to the extent reasonable, but he shouldn't overly worry about it. E left the office, expecting to return in 10 days for the new crown to be inserted.

On the fourth day after this visit, E noticed that his stool was blood-tinged, so he called Dr. M to learn whether that might be related to the dropped crown, but Dr. M did not think so. He did, though, advise E to speak with his primary care physician if things worsened or even remained the same. The stool got redder toward the end of the week, so, that Sunday, he appeared at an urgent care center, where, upon hearing about the dental crown incident, the physician ordered an abdominal series of radiographs, which located the crown, appearing to be stuck in place at a sharp bend in E's colon. Arrangements were made for E to have a colonoscopy the following morning at a local hospital, where E was admitted for the night.

Under deep sedation, a gastroenterologist removed the crown from the colon by using a grabbing instrument. When the crown was examined after removal, the gastroenterologist reasoned that the metal edge of the crown that projected below the porcelain portion — the margin — had likely dug its way just a small amount into a fold in the wall of the colon, preventing it from moving beyond that point to be expelled. Because of E's underlying medical conditions, he was kept in the hospital until the next day, at which time he was discharged without any problems or complications.

Legal action

Although E was willing to let the situation end without any further action, his wife was particularly annoyed about the hospital, anesthesiology, and gastroenterology fees, which were not covered by E's high-deductible medical insurance policy, as well as what she viewed as Dr. M's lack of caring, as demonstrated by his having never followed up with E about what had occurred.

An attorney was brought on board to sue Dr. M for dental malpractice, so that the out-of-pocket costs and a sum for pain and suffering could be recovered. The attorney's first step was to contact Dr. M's malpractice carrier, specifically its regional claims consultant. When all records were obtained and reviewed, the claims consultant explained to Dr. M that a supportive defense expert was unable to be located, even by a local defense attorney, so that a liability defense could not be mounted, other than by way of Dr. M acting as his own liability expert.

Dr. M realized that this was far from an ideal approach, so he agreed to attempts to settle the case, which was accomplished for a relatively modest amount of money.

Takeaways

Under the best of circumstances, maintaining a grip on small objects placed in the mouth, using wet gloves, is fraught with the risk of losing control of the object — here a crown. When treatment is performed in the back of the mouth, that risk is magnified, and when the patient's anatomy makes the working space smaller than usual, the risk further increases. Adding to that, the gravitational considerations of a supine (rather than upright) patient maximize the likelihood of a dropped object being swallowed or aspirated. Each of these "weak points" can generally be mitigated: oropharyngeal packs are placed to try to physically block the backward and downward path, particularly when rubber dam cannot be used; working with a watchful, suctioning chairside assistant provides extra hands, extra eyes and extra protective devices; and seating a patient in as upright a position as possible can mean the difference between a dropped object falling harmlessly into the floor of mouth where it is easily retrievable, and a swallow/aspiration event.

Any and every time that an object is placed into the mouth, or one becomes free-floating in the mouth, and cannot be accounted for, it should be assumed to have been swallowed or aspirated unless proven otherwise, generally by radiographic evidence either way. As a general rule, the sooner the patient is able to be placed into the care of medical colleagues for locating and treating, the less the ramifications will be. That does not necessarily mean that dental procedures must always be stopped in their tracks, but it does mean that, as soon as it is safe for the patient to move on for definitive care, the better off they will usually be. Because physicians are often less than fully aware of dental materials and instruments, it is helpful to them if a photo example, or actual example, is provided to the patient to pass on to their physicians, so that they know exactly what they are looking to locate.

Two considerations which quite often lead patients to seek legal advice are unexpected and unreimbursed costs, and a perception that their dentist did not truly care about them, particularly when things did not go as planned. The former is unpredictable, and it ended up here as one of the main drivers toward legal action, but the latter can almost always be avoided. Prompt and repeated follow-up communication, by the dentist, rather than an office staff member, with patients; and demonstrating a genuine interest in patients, as people and not only "receivers of dentistry"; can go a long way toward heading off involvement of lawyers.

Not all patients and not all similar procedures are the same, whether because of underlying medical issues, patient anatomy, patient size, patient attitudes, or limited mobility. So, a one-size-fits-all approach is rarely, if ever, a helpful treatment mindset to adopt.

Finally, we address the circumstance here, where no liability expert could be found to help to defend Dr. M. While not very common in the defense of dental malpractice claims, it does occasionally pop up. In most, if not all, jurisdictions, dentists are legally permitted to serve as their own experts. But in the eyes of jurors, that is often a difficult sell. In this situation, as well as all other litigation-related issues, dentists are counseled by their defense attorneys, whether the news is easy to hear, or not.

Summary of takeaways:

Take an objective, measured approach to patient communication
Avoid criticizing prior care without full context
Maintain thorough documentation to support care decisions

Summary of takeaways

A signed consent form alone is not enough — patients should also be verbally informed of all risks, benefits and alternatives associated with a procedure, by way of back and forth conversations, and those discussions should be thoroughly documented.
Billing disputes and inaccurate procedure coding can damage patient trust and may become the catalyst for malpractice claims.
Upcoding procedures can result in payer disputes, loss of network participation, regulatory concerns, and increased legal exposure.
