The fact that many dentists practice dubious alternative therapies receives relatively little attention. In 2016, for instance, Medline listed just 31 papers on the subject of ‘complementary alternative medicine, dentistry’, while there were more than 1800 on ‘complementary alternative medicine’. Similarly, I have discussed this topic just once before on this blog. Clearly, the practice of alternative medicine by dentists begs many questions – perhaps a new paper can answer some of them?

The aims of this study were to “analyse whether dentists offer or recommend complementary and alternative medicine (CAM) remedies in their clinical routine, and how effective these are rated by proponents and opponents. A second aim of this study was to give a profile of the dentists endorsing CAM.

A prospective, explorative, anonymised cross-sectional survey was spread among practicing dentists in Germany via congresses, dental periodicals and online (n=250, 55% male, 45% female; mean age 49.1±11.4years).

Of a set of 31 predefined CAM modalities, the dentists integrated plant extracts from Arnica montana (64%), chamomile (64%), clove (63%), Salvia officinalis (54%), relaxation therapies (62%), homeopathy (57%), osteopathic medicine (50%) and dietetics (50%). The effectiveness of specific treatments was rated significantly higher by CAM proponents than opponents. However, also CAM opponents classified some CAM remedies as highly effective, namely ear acupuncture, osteopathic medicine and clove.

With respect to the characteristic of the proponents, the majority of CAM-endorsing dentists were women. The mean age (50.4±0.9 vs 47.0±0.9years) and number of years of professional experience (24.2±1.0 vs 20.0±1.0years) were significantly higher for CAM proponents than the means for opponents. CAM proponents worked significantly less and their perceived workload was significantly lower. Their self-efficacy expectation (SEE) and work engagement (Utrecht work engagement, UWE) were significantly higher compared to dentists who abandoned these treatment options. The logistic regression model showed an increased association from CAM proponents with the UWES subscale dedication, with years of experience, and that men are less likely to be CAM proponents than women.

The authors concluded that various CAM treatments are recommended by German dentists and requested by their patients, but the scientific evidence for these treatments are often low or at least unclear. CAM proponents are often female, have higher SE and work engagement.


These conclusion are mostly not based on the data provided.

The researchers seemed to insist on addressing utterly trivial questions.

They failed to engage in even a minimum amount of critical thinking.

If, for instance, dentists are convinced that ear-acupuncture is effective, they are in urgent need of some rigorous education in EBM, I would argue. And if they use a lot of unproven therapies, researchers should ask whether this phenomenon is not to a large extend motivated by their ambition to improve their income.

Holistic dentistry, as it is ironically often called (there is nothing ‘holistic’ about ripping off patients), is largely a con, and dentists who engage in such practices are mostly charlatans … but why does hardly anyone say so?
