Behavioral Sciences in the Promotion of Oral Health

The importance and value of behavioral sciences in dentistry have long been recognized, and their contribution to dental education, research, clinical practice, and oral health policy has been significant over the past half century. Over time behavioral sciences have expanded our understanding of oral health beyond "disease" to a broader biopsychosocial concept of oral health. This in turn has led dentistry away from a focus of "treatment" to oral health "care," notably in the new millennium. Key oral health behaviors have been identified for more than half a century: the importance of diet, oral hygiene, dental services, and other factors. Various behavioral models and theories have been proposed, particularly since the 1970s, providing useful frameworks with sound psychological basis to help understand the paths of oral health behaviors. These models draw on theories of self-efficacy, motivation, counseling, and "behavior change." Since the 1980s, there has been a greater understanding that these behaviors often share a common pathway with the etiology of other diseases (common risk factors). Furthermore, the relationship between individual factors and the broader environmental factors has been increasingly emphasized since the 1990s, leading to a united call for action in addressing oral health inequalities. Within the past decade, there are useful examples of models, frameworks, and techniques of behavior change with respect to oral health, involving planning, prompting, encouraging, goal setting, and/or motivating. In particular, there is a growing interest and use of motivational interviewing. Likewise, behavioral therapies, such as cognitive behavioral therapy, are increasingly being employed in dental practice in the management of dental anxiety, pain, and psychosomatic dental and oral problems, with promising results. Recommendations are outlined for future directions for behavioral sciences in the promotion of oral health.
