Financial conflicts of interest in dentistry: how much money do providers receive from industry?

The purpose of this retrospective, observational study was to characterize the amounts and types of healthcare industry payments made to dental care providers in 2017. Data were collected from the Open Payments database of the US Centers for Medicare & Medicaid Services. Dentists were classified as providing general services or services in 1 of 9 specialties recognized by the American Dental Association (prior to the recognition of dental anesthesiology). The value and nature of each payment made to providers were recorded, and descriptive statistics were calculated. Distributions across dental specialties were compared with analyses of variance. In 2017, US dentists received a total of 321,627 industry payments totaling $110,750,601. The most money was spent on service fees ($37,333,870; 33.7%), followed by consulting fees ($12,983,013; 11.7%) and royalties and licenses ($11,426,776; 10.3%). Each provider received a median payment of $63.27 (range, $0.21-$22,931,027.12) spread over 2 payments (range, 1-285). Participation rates among dental specialists ranged from 19% to 62%, and the highest rates were found among orthodontists (61.8%), oral and maxillofacial surgeons (55.7%), and periodontists (54.6%). The greatest median payments per provider were made to specialists in oral and maxillofacial radiology ($187.52), periodontics ($127.31), and oral and maxillofacial surgery ($123.39). The mean number (P < 0.01) and amount of payments (P < 0.01) per provider differed significantly across all specialties. The majority of dentists in this study received less than $200; however, the distribution of payments was positively skewed by a few top earners. The effect of these payments on clinical practice remains to be determined.
