Dental practice is subject to regulation by many agencies. The most formidable regulatory body for many practitioners is their State Licensing Board whose charge is protecting the well-being of the public. Because of the great power differential between the practitioner and the regulatory body, coupled with the limited due process requirements afforded the practitioner, it is important to know your board's policies and procedures and to respond to board inquiries appropriately. Practitioners would be wise to obtain appropriate legal counsel when responding to inquiries by most regulatory bodies and especially to inquiries made by their State Licensing Board. The objective of this article is to provide a general overview of the regulatory process and raise issues that you, as a health professional, must consider when confronted by an inquiry from a regulatory agency affecting the practice of dentistry. Although the major focus will be on a State Licensing Board, the general principles are applicable to most regulatory bodies.
