Public and Professional Perceptions of the Scope of Practice of Oral and Maxillofacial Surgeons.

Purpose: To investigate and compare the general public's, general dentists', and primary care physicians' level of knowledge of the scope of practice of oral and maxillofacial surgeons (OMSs). We hypothesized that there is a generalized lack of knowledge of the scope of practice of oral-maxillofacial surgery, with the general public being the least informed and the general dentists the most educated.

Methods: A cross-sectional survey study was conducted via a mail-out survey that was delivered to a random sample of the general public, general dentists, and primary care physicians in Ontario, Canada. A total of 1800 participants were selected. The survey consisted of a demographic screener along with 24 clinical scenarios in which the participants could select all the specialists they thought were capable of completing the treatment. Inferential statistics were computed using a chi-square test to compare responses between the groups and identified any significant differences between subjects for each of the 24 scenarios with P value set at 0.05.

Results: Total response rate of 50.1% (n = 902) was achieved. The majority of health professionals (100% dentists, 95.5% primary care physicians) have heard of oral-maxillofacial surgery, in contrast to only 73.7% of the general public (P < .001). There was a general lack of awareness of oral-maxillofacial surgery scope of practice by all groups wherein OMSs were selected less than 50% of the time in 10 (general dentists), 14 (primary care physicians), and 16 (general public) of 24 clinical scenarios.

Conclusion: Greater than 25% of the general public are unaware of OMS. More concerning, the general public and health professionals as a whole are unfamiliar with the full scope of practice of OMSs. For enhancing access to care by qualified specialists, educational programs highlighting key aspects of oral-maxillofacial surgery should be developed and distributed to all populations.
