Is Dentistry Science Based? – Science-Based Medicine

In at the moment’s social media laden local weather, it is de rigueur for individuals to instantaneously react and turn out to be concurrently defensive and offended when any of our sacred cows are challenged.  It’s part of the human situation and we will’t assist ourselves.  We dentists had the opportunity to feel assaulted a few weeks ago when an article in The Atlantic by Ferris Jabr entitled “The Truth About Dentistry:  It’s much less scientific—and more prone to gratuitous procedures—than you may think” was revealed.  Dentists worldwide have been summarily outraged, and vast hordes of people that for some purpose aren’t fond of dentists collectively pointed their virtual fingers at us and nearly screamed “AHA!  WE KNEW IT!!”

So I suppose the purpose of this publish is to “unpack” the article and try and objectively assess the claims put forth therein. Furthermore, I want to give a superficial overview of what science based mostly dentistry is, with some wonderful links and different assets do you have to need to dive in additional.   I will attempt my greatest to not be too defensive and to put out my case objectively.  We’ll see how nicely I do.

The Atlantic Article

I don’t need to spend an entire lot of time criticizing the elements of the article with which I disagreed; not only will that look like very defensive on my half (which, should you recall, I promised I’d attempt not to be), but primarily as a result of it was coated rather well in different posts by my associates and colleagues Dr. Alan Imply (hyperlink) and Dr. Chip Payet (link).  When you learn their items, you’ll get a way of how Mr. Jabr maybe misrepresented the difficulty a bit in some areas.  Dr. Payet actually picks aside the positives and negatives concerning the article, and deftly explains why certain areas of dental analysis may be so troublesome to undertake.  Dr. Mead’s article addresses Mr. Jabr’s piece from a journalistic perspective- that it perhaps is a bit sensationalistic and hyperbolic, and framed in such a approach to get loads of ‘clicks’ which is the aim of many publications lately, even when accuracy and equity are sacrificed in the course of.  As for me, I really feel that it was a bit heavy handed and targeted too much on the evil doings of 1 derelict unethical dentist who did horrible issues to his patients- inflicting pain, costing them vital and unnecessary costs, and violating the sacred trust that each one health care professionals attempt to take care of with the individuals of their care.  What that rogue felony dentist did was tangential to the actual query “How scientific is dentistry?”

Because I don’t need to depart all the heavy lifting to Al and Chip, I’ll give a couple of examples of where Mr. Jabr went a bit overboard, resorting to a bit of worry mongering in addition to simply getting a couple of issues improper.  When he mentioned certainly one of “Dr. Evil’s” sufferers, he stated that “she was born with one tooth trapped inside another…”  which isn’t actually a factor in dentistry.  I think that perhaps a tooth was congenitally lacking in this case, or perhaps didn’t erupt correctly and remained impacted.  When a process was described thus:  “He also chiseled out her bridge…”  I’ve to smile a bit because most dentists I know not often, if ever, use a chisel when doing fillings, crowns, and bridges.  This, for my part, was simply the writer’s method of casting an evil and grasping mild on the procedures executed by that evil and greedy dentist.  To generalize from the one to the all is a bit disingenuous, and I say this with no offense taken and never being defensive.

I additionally bristled when the article said:  “A multitude of factors has conspired to create both the opportunity and the motive for widespread overtreatment in dentistry. In addition to dentistry’s seclusion from the greater medical community, its traditional emphasis on procedure rather than prevention, and its lack of rigorous self-evaluation, there are economic explanations.”  This accusation paints all dentists as greedy and uncaring, who solely need to do costly remedy on their hapless, powerless victims.  Opposite to his faulty assertion, the emphasis in trendy dentistry is on prevention, but understand that we aren’t in charge of our sufferers’ danger elements and way of life decisions.  To accuse us thus is akin to accusing cardiac surgeons of only being procedure oriented and never preventive.  Main care physicians from cradle to grave, as well as specialists, ceaselessly try to teach their sufferers on preventive care- good food regimen, sufficient sleep, exercise, not smoking, and so forth.- but what their patients choose to do with that info is up to them.  Those of us in the “body repair” enterprise are merely there to try to decide up the pieces once the injury has been achieved.  To color us all as cash grubbers who only do procedures if they’re worthwhile is a bit disingenuous and unfair.

That being stated, Mr. Jabr does rightfully mention the science (or lack thereof) of the six month recall that is commonplace in dentistry.  I wrote about that very subject last yr, and while not scientifically rigorous, that doesn’t mean it’s incorrect or that we try to mislead our patients.  I wish he would have been “fair and balanced” on this area however once more, his angle was to painting dentists as non-scientific grasping predators.

Dentistry and Science

Is dentistry scientific?  That’s the crux of this weblog publish and I hope I can lay out a strong case for the affirmative.  I do consider that dentists are more than tooth carpenters and gum gardeners, and while Mr. Jabr factors out that dentists solely have four years of post-graduate schooling and coaching (until one pursues a specialty), he failed to tell his readers about what our schooling entails.  I gained’t bore you with the small print, but please indulge me while I bore you with the small print.

  • To be accepted to an accredited dental faculty in the USA (standards are comparable in different nations), one must move the Dental Admissions Check (DAT), which exams the applicant’s information in such subjects as Biology, Common Chemistry, Organic Chemistry, Studying Comprehension, Perceptual Capability, and Quantitative Reasoning.
  • Whereas a Bachelor’s degree shouldn’t be required, most dental students do have a Bachelor’s degree, often in a science subject similar to Biology or Biochemistry.
  • Once in dental faculty, our primary science schooling mirrors the training present in medical faculties, encompassing anatomy, physiology, immunology, embryology, histology, pathology, pathophysiology, microbiology, biochemistry, neuroanatomy, and so forth. In reality, once I was in dental faculty (College of Oklahoma), we took our primary science courses with the medical students.  So I do assume it’s truthful to say that we now have an honest scientific and medical foundation.
  • So as to apply dentistry, we must cross a complete board examination which critiques our information in the primary sciences and dental subjects, followed by completing work on reside sufferers.  To take care of our licenses, we must full vital numbers of hours of continuous schooling annually.

Dental research within the 21st century is vast and various, from enhancing the materials we use for fillings and crowns, to advances in know-how, to Buck Rogers sort stuff reminiscent of creating new tooth from stem cells, genetic testing and therapies, and different superb biotechnologies.  Yegane Guven wrote a superb assessment on the scientific foundation of dentistry, areas of present and future analysis, and the way this is translated into dental schooling and apply.

Evidence Based mostly Dentistry (EBD)

On this weblog and elsewhere, distinctions have been made between the terms “Evidence Based Medicine (EBM)” vs. “Science Based Medicine (SBM).”  The same differences and debates could possibly be made in the realm of dentistry, but for us the term “Evidence Based Dentistry (EBD)” is extra extensively utilized, subsequently I might be utilizing EBD on this publish with the understanding that I’m applying the concepts and philosophies of SBM to the topic.  The American Dental Association itself has an arm referred to as The Middle for Proof Based mostly Dentistry, which is a wonderful resource for dentists and non-dentists alike.  They host workshops and training for dentists and others within the dental subject, helping us to use the perfect scientific evidence into our medical practices for the good thing about the sufferers we serve in addition to the general public at giant.

Based on the website, EBD might be defined as:

“an approach to oral healthcare that requires the judicious integration of systematic assessments of clinically relevant scientific evidence, relating to the patient’s oral and medical condition and history, with the dentist’s clinical expertise and the patient’s treatment needs and preferences.”

The most effective in depth discussions I’ve learn on EBD is an article by Afrashtehfar and Assery (hyperlink), and for these of you who need to do a deeper dive on the subject, I extremely advocate reading it.

This EBD triad of care encompasses the required elements of what constitutes the usual of look after dentistry:  greatest scientific proof, the wants and preferences of the patient, and the medical experience of the practitioner.  If any facet of this strategy is violated (as it most definitely was in the Atlantic article), then your complete system of high quality moral care breaks down.  An essential point to make is that in drugs, dentistry, and every different space of well being care, we depend on the “best available scientific evidence.”  Science (including drugs and dentistry) progresses sequentially, in matches and starts, constructing upon earlier information.  Therapies and procedures which are in use immediately may be overturned tomorrow if adequate evidence dictates it. This is the power, not a weak spot, of the scientific process.


How did I do?  Did I come throughout as offended or defensive?  I really tried not to, but when I did, I apologize.  What I do hope is that you simply, pricey reader, have come away with a greater understanding concerning the apply of dentistry as it takes its rightful place beneath the larger umbrella of Science Based mostly Medicine.

What are you able to as a dental shopper do to ensure that you’re receiving applicable dental recommendation and remedy so that you simply don’t turn out to be a victim of an unethical practitioner just like the dentist within the Atlantic article?  The excellent news is that in case you are a frequent reader of this weblog, you’re in all probability 99% of the best way there.  You’ve gotten discovered the instruments of science and important considering and are capable of apply them in your every day life.  That being stated, listed here are some other steps you possibly can take:

  • “Patient friendly” web sites such because the Middle for EBD (mentioned above), the Cochrane Library, and PubMed are wonderful places to research current proof and tips in dentistry and different fields.
  • Never hesitate to ask your dentist or hygienist to elucidate your whole options (including the option of no remedy at all), what the risks and advantages of a procedure are, all prices, and the expertise and experience of the supplier. When you don’t understand the remedy, ask questions until you do.  Should you really feel that you are being “sold” on any remedy, it is advisable to get a second (and perhaps even third) opinion.
  • Seek recommendation from goal science based mostly dentists on social media, dental faculties, or other platforms. We’re all the time prepared to help demystify dentistry and give common advice to individuals who contact us.
  • Hold reading Science Based mostly Medicine and other blogs who promote a science based mostly worldview and foster essential considering.

It was a tragedy that the dentist in The Atlantic article took such wanton advantage of his patients.  Fortuitously, conditions like this don’t occur very often, but there are charlatans out there in all walks of life, so to arm oneself with the tools of important considering is likely one of the greatest defenses towards such mistreatment in the dental office and elsewhere.
