Tobacco or oral health: past progress, impending challenge.

BACKGROUND AND OVERVIEW: A number of significant events and research findings during the past 15 years have led to the dental profession's growing involvement in tobacco-use intervention activities. The author presents an overview of events and people responsible for the progress in furthering the cause of dentistry's activism in tobacco-use prevention and control. CLINICAL IMPLICATIONS: Dentistry has led the health professions in establishing a protocol for the prevention of tobacco use, a health behavior that causes or contributes to various oral diseases and adverse conditions. Dentists practicing in the 21st century cannot ignore patients' tobacco use. Treatment prognoses for periodontal therapy, wound healing, dental implants, cosmetic treatments and cancer therapy all are compromised by patients' tobacco use. Dentists must know what to do and say to prevent patients' tobacco use and aid patients in its cessation.
