The hierarchy of approaches to tobacco control

Abstract

Tobacco represents the single most preventable cause of disease and death in the world today. Of 260 million male deaths in the developed world between 1950 and 2000, it is estimated that 50 million will be due to smoking. In the oral and craniofacial region tobacco use has been associated with the occurrence of cleft palate, periodontal disease and tooth loss, and a variety of soft tissue lesions including oral cancer. For example, smoking is estimated to account for 92% of cancers of the lip, oral cavity and pharynx. Few studies have examined relative efficiency of the many different approaches to tobacco control but, in general, legislative approaches such as increasing tobacco taxes and prohibiting advertising are most effective and those based on printed educational materials and cessation groups, the least effective. In all cases, advice or intervention by health care professionals ranked among the most effective non-legislative approaches to control. A very wide range of professionally-based interventions have been described, including pharmacologic interventions, behavioral approaches and group counseling. The dental profession has a unique opportunity to influence tobacco use by their patients. Its use is almost always immediately evident to the dentist or dental assistant in terms of odor, staining, poor oral hygiene or obvious oral disease. There is also a tendency for the length of personal contact with the dentist to be greater than with a physician. Guidelines are now available that provide the dental professional with advice on the best approaches to tobacco control with their patients.
