A dentist is setting up the CBCT scanner for a patient.

Background Facts

A 61-year-old male patient, F, presented to a periodontist, Dr. P, on referral from his general dentist, for evaluation and potential placement of bilateral mandibular implants. The patient reported a benign medical history, but confided that he had not had a medical exam or laboratory studies in years; Dr. P encouraged her patient to have a medical exam as soon as possible, and F assured her that he would. After performing a clinical oral examination, which revealed that the patient was missing all lower molars, Dr. P had a panoramic radiograph taken. Review of the film demonstrated approximately 10-12 mm of mandibular bone superior to the inferior alveolar canals bilaterally, but Dr. P palpated a significant lingual concavity on the left side, so she thought that a CBCT would provide the best assessment of whether implant placement would be a viable treatment, and, if so, what types and sizes of implants could be employed. Because Dr. P did not have a CBCT machine in her office, and she did not feel comfortable interpreting those studies, she referred F to a radiology facility which had an oral and maxillofacial radiologist, Dr. R, on staff.

F made an appointment at the facility after Dr. P advised him that she had discussed the case with Dr. R. Dr. R was asked to evaluate for available mandibular bone so as to be able to place endosseous implants in the posterior regions, preferably 2 fixtures on each side. Dr. R read the study and advised Dr. P, in a written report, that there was adequate bone to place a 12 mm implant at the site where tooth #19 had previously been, and 10 mm fixtures at the sites where teeth # 18, 30 and 31 had been, all of standard (3.5-4.2 mm) diameter. The written report was messengered to Dr. P with the films, but Dr. P reviewed only the report and not the films. Four implants were uneventfully placed, they integrated with bone, and all were restored without complication approximately 9 months after the CBCT was completed.

About 6 weeks after that, F saw an internist, Dr. I, for a physical exam. F’s prostate felt rather hard to palpation, and his PSA was 8.9 ng/ml. Dr. I referred F to a urologist, who had F undergo a work-up, which revealed Stage IV adenocarcinoma with metastases to the left sphenoid bone. F casually mentioned to the urologist that he had a CBCT in preparation for dental implants, and nobody had said anything about any abnormalities in any bones of the head; F obtained those films and provided them to a radiologist recommended by the urologist, who concluded that there had been a suspicious lesion in the left sphenoid which extended into the sphenoid sinus, clearly visible on the CBCT. F opted against the multiple approach cancer therapies once he was told that his chances of survival were poor, given the tumor’s staging, and he passed away in under 2 years.

Legal Action

In his last months, F heard opinions from a number of people close to him that, if the CBCT had been properly read, the metastatic lesion would have been detected nearly a year before it was, which would have allowed him to be successfully treated. He spoke with an attorney, but did not have the willingness to get involved with litigation in his weakened state. However, his family members, as his estate, chose to sue for the pain he suffered before dying and for his premature death.

A lawsuit was begun, naming Dr. P and Dr. R as defendants, asserting dental malpractice against both of them for failing to adequately review and identify the metastatic sphenoid lesion, thereby causing F to be deprived of an opportunity to be successfully treated. Both dentists were provided with legal representation by their malpractice carrier, although separate attorneys were assigned because of the potential that the legal interests of the defendants might not be fully aligned.

Discovery and Case Resolution

During her deposition, Dr. P took the position that she was not skilled in interpreting CBCT studies, which was the exact reason that she did not maintain her own machine and review studies on her own; instead, as she did here, she always referred patients in need of pre-implant CBCTs to oral and maxillofacial radiologists, who were specifically trained for that purpose. She did not blame Dr. R, but simply persisted that she knew she was not capable of interpreting these studies.

Dr. R acknowledged at his deposition that there was, in fact, a radiographically visible lesion encompassing the sphenoid bone and adjacent sinus, but, at the time of initially reading the CBCT, he was focused solely on the issues surrounding implant placement, so he failed to see the mass which was some distance away from the area of his concentration. Realizing that Dr. R had essentially testified to his own negligence, his attorneys worked to disprove the causation prong of the estate’s claim, namely that a diagnosis a year earlier than it came would have given F a fair chance at survival.

To that end, Dr. R’s counsel retained an oncology expert, Dr. E, who was of the opinion that it was “unlikely” that an earlier diagnosis in this case would have made any difference in the potential for F to have survived, based upon the existence of a metastasis, the usual characteristics of malignancies of this type, and the specific histological features of the primary tumor. However, Dr. E advised the attorneys for Dr. R that other experts might legitimately disagree with him on this issue, as there are speculative and subjective aspects at play.

At trial, before Dr. E testified, Dr. R heard the testimony of the plaintiff’s expert on the issue of causation – that there would have been a real chance for curative treatment, or at least treatment which would have meaningfully extended F’s life, if the lesion had been timely detected on the CBCT – and found it to be compelling and believable, raising a concern that the jury could find against him for more than his policy limits. With his authority, his attorneys negotiated a settlement with the plaintiff’s attorney. Upon reaching that agreement, the case against Dr. P was discontinued, with the plaintiff’s attorney privately acknowledging that it would have been difficult to prove a case against her, given her referral to a specialist regarding an issue about which she openly recognized her own lack of expertise.

Takeaways

One of the overriding concepts addressed by this case study is that the teeth, jaws, and oral cavity as a whole lie close to “non-dental” areas of the body, so conditions related to those other areas may affect that which dentists do. And physiologic or anatomic problems in even distant locations may also have an impact upon areas treated by dentists. So, dentists best serve their patients by maintaining a sense of awareness of the construct that, colloquially speaking, “the teeth are connected to the body”, and vice versa, and with that comes a patient responsibility that extends beyond the teeth, jaws, and oral tissues.

In this case, Dr. P recognized where she had expertise and where she did not, and based upon the latter, made an appropriate referral to a specialist whose proficiencies would be able to fill in the open gap. As we see it, that was the prudent course of action for her to have taken, and that bore out positively for her in this litigation. But that should not be presumed to mean that every referral will eliminate liability in every situation, because all circumstances are fact-based and individual.

What was avoided in this case was jousting – or the “throwing under the bus” – against Dr. R by Dr. P. Unfortunately, one dentist blaming another and voicing that to patients, is far from uncommon and it is a frequent act that leads patients to engage in litigation when results are not what were expected. Here, Dr. P was able to protect her own position without criticizing the actions of Dr. R; doing so meant taking ownership of her own limitations, and that level of professionalism was apparently not lost on the plaintiff’s attorney.

While Dr. P did not know, and could not have known, at the time that pushing her patient to obtain a medical exam would lead to her later being implicated in a malpractice suit, it was, nevertheless, exactly what was in the patient’s best interests. Had she not done so, F’s disease would likely not have been discovered until he became quite ill, so proof of the causation prong would have been far more difficult for the plaintiff’s attorney and expert to achieve, and would likely have stood as a bar to the case having been brought in the first place. But again, Dr. P upheld her ethical obligations, and that is always the proper approach, regardless of the outcome.

Dental and medical specialists exist to maximize the quality of patient care. General practitioners are not expected to be experts in every area of their profession, and even specialists, who may well have high levels of expertise in their limited fields, are not authorities on everything. So, appropriate referrals are always prudent and are hopefully appreciated by patients. Acknowledging limitations in knowledge or ability is not something to be ashamed of, but instead something to be embraced; doing so supports ethical principles which guide the practice of dentistry, benefits patient care, and lessens the likelihood of becoming a defendant in a dental malpractice lawsuit.

Finally, as we have noted in earlier case studies, a plaintiff must prove, through expert testimony, that not only was the defendant dentist negligent, but that such negligence directly caused the injuries complained of. Without expert proof of all of those elements, to the satisfaction of a judge and a jury, the defendant dentist will prevail. So, while Dr. R admitted to his own negligence, that alone was not determinative of the outcome: a causal connection between that negligence and the claimed injuries was required as well.

Dentists will learn how sedation missteps can lead to a malpractice claim and Dental Board action. This case highlights why understanding state sedation requirements, assessing patient risk, and preparing for emergencies are essential to managing malpractice risk.

Key concepts

Dentist sued after unpermitted sedation led to a medical emergency
Dental Board action tied to state sedation permit requirements
Why patient risk factors matter before providing sedation

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.

In this real-life case study, dentists will learn how a swallowed crown can quickly become a patient safety event and lead to a malpractice claim. See why prevention, timely follow-up, and patient communication are essential aspects of reducing risk.

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

Background facts

Dr. Y was a general, restorative dentist who recently moved into a suburban community—with great public schools—to both live and work. The area's dentists were, generally speaking, busy but not bursting at the seams, so Dr. Y realized that it would not be easy for him to establish his practice with so much competition. His approach would be to sign on to as many dental insurance panels as he could, hoping to use that platform as a foundation upon which to build a patient base. It took a couple of years, but his practice grew.

It was not that Dr. Y would "manufacture" dentistry to perform upon new patients where that need did not exist, but he was what other dentists in the neighborhood described behind the scenes as "hyper-critical" in his evaluations of the dentistry that had been done by prior dentists. R had been a long-term resident of the area, having never had dental insurance until her recent job change. She had completed implant-supported bridgework on both arches some 6-8 months ago, which had cost her a significant amount of money, and she was in the midst of a very slow process of getting used to functioning with the prostheses. With her new employer now providing her with dental insurance—a plan which Dr. Y, but not her prior dentist, Dr. K, accepted—she presented to Dr. Y as a new patient.

At the initial visit, Dr. Y took a full mouth series of radiographs and did a thorough clinical examination. When R mentioned that she "just didn't feel comfortable" with the new dentistry in her mouth, Dr. Y told her that he knew why: the abutments and pontics were overbuilt, with inadequate embrasure spaces; some of the margins were open, although slightly; and the overall dental anatomy did not allow for self-cleansing, making it "a set-up for periodontal disease.” Dr. Y suggested that all of the prosthetics be removed and replaced. Even with R's dental insurance contributing a fair amount to the cost of the proposed treatment, she would still have to pay a large amount of money out of pocket and endure a months-long process. R was very upset, to say the least, focusing that displeasure on Dr. K; she had always known that a replacement of Dr. K's work would likely be required down the road, but she did not expect that so soon after it was inserted.

Dr. Y removed the existing bridges, replaced the implant abutments, re-prepared the natural teeth, impressioned and temporized the mouth, and ultimately inserted new upper and lower cases. R was no happier with the new work, but Dr. Y told her that there was only so much he could do with the underlying foundation that Dr. K had "inadequately established,” so R would simply have to adjust. She never fully did.

Legal action

With R continually complaining to family members and friends about how unhappy she was, not only dentally, but also because of the money she had paid both Dr. K and Dr. Y, while exhausting her annual dental insurance benefits so early in the calendar year, she was encouraged to seek out an attorney who might have some solutions for her. R's newly retained attorney obtained the dental records of Drs. K and Y, as well as a narrative from Dr. Y, in which he was quite critical of Dr. K's work product, which was directly responsible for the need to exchange it and for the inability to create a more ideal replacement (due to the underlying damage it/he had caused).

When Dr. K reported the contact from R's attorney to his malpractice carrier, he was provided with defense counsel, who was able to obtain the records and report from Dr. Y. Dr. K was in literal disbelief at what he saw in writing, but he knew that it would be a difficult task, from a dental standpoint, to demonstrate the quality of his work, with it having been removed and replaced. At the same time, he felt bad for R, his patient of many years, whom he believed had been sold an inaccurate story, for the sake of Dr. Y's financial gain.

With Dr. K's counsel functioning as an intermediary at Dr. K's request, an offer was made to refund to R all that she had paid to Dr. K, in order to stave off the prospect of a lawsuit. R, through her attorney, accepted that offer, with the money changing hands once R executed a Release of Liability document.

Takeaways

As healthcare professionals, dentists are ethically obligated to advise patients regarding the conditions of their mouths, including the status of existing dental work. But without having ever stood in the shoes of a prior-treating dentist, and not knowing what challenges and limitations might have been placed upon them, or how the patient took care of themselves dentally after that treatment, blanket criticisms that do not take any of these potential factors into account are known in the malpractice world as "jousting" —not the medieval game involving horses and lances, but with similar effect. Part of professionalism is being able to candidly communicate with patients without denouncing the work of others, absent full knowledge of all contributing factors. Here, while Dr. Y acted appropriately by advising R of his findings—presuming that he did, in fact, find deficiencies and problems—he stepped into the jousting arena by doing so in a manner that made certain presumptions of blameworthy wrongdoing. It is a fine line to walk, and one to be figured out by all practitioners. Jousting, as compared with notifying, is a significant driver of dental malpractice claims; why that practice is as common as it is, perhaps more so than in other professions, is a speculative exercise for consideration elsewhere.

Dr. K's decision to try to resolve R's complaints by offering, and ultimately providing, a refund was a personal one, considering all of the issues involved with defending a protracted dental malpractice case, as compared with taking all of that off of his plate quickly. Refunds are far from uncommon in dental practice; when provided, dentists are wise to protect themselves legally by obtaining a Release of Liability (ROL), signed by the patient, in exchange for the returned money. In essence, a ROL in this context states that the patient is willing to accept a monetary benefit, while relinquishing the right to later sue the dentist regarding the course of conduct that led to that refund. As with all legal documents, ROLs are best prepared and overseen by attorneys, who can assure that the process is carried out in the most appropriate manner, so as to afford the best level of protection. We do note, however, that no ROL will prevent a patient from subsequently making a complaint to a state Dental Board, as the right to report to government entities cannot be given up through a civil process, such as a refund or a settlement. For better or worse, that is the way it is.

Dr. Y's preparation of a narrative for an attorney is an everyday occurrence. In many jurisdictions, attorneys for patient-plaintiffs are required to obtain some sort of statement, whether written or otherwise, from a dentist, in which that dentist states, in terms of varying specificity, that the treating dentist who is being considered as a potential defendant violated the standard of care, thereby leading to damage to the patient. Such statements are opinions, and opinions vary much of the time, but that is how the system works. To add to the difficulties in defending cases like this, particularly involving restorative dentistry, the work that is later claimed to have been deficient will, by definition, have been removed and replaced, so there can be no after-the-fact reviewing of the criticized work by the defendant and/or his/her defense expert. That serves as yet another reason that documentation (including post-placement radiographs, when appropriate) is so important, as it might well be the only "living" evidence of steps taken and rationales for doing so. Time-consuming as it is, documentation is not something to shortcut: that includes dentists writing their own chart entries, rather than having an assistant or other staff member do it for them.

Summary of takeaways:

Criticizing prior work without full context can increase malpractice risk.
Keep patient communication objective and avoid assigning blame.
Thorough documentation is critical for defending care decisions.
