Effective smokeless tobacco intervention for dental hygiene patients.

This study was designed to test the effectiveness of a smokeless tobacco (ST) intervention delivered in the oral healthcare office setting. A total of 518 male ST users were identified by questionnaire in clinic waiting rooms and then randomly assigned to either a usual-care control group or a special intervention group. Dental hygienists took the primary role in delivering the intervention, which consisted of a soft-tissue examination with special attention to oral lesions, advice to quit ST, distribution of self-help materials, a short video on why and how to stop using smokeless tobacco, and encouragement to set a quit date. Follow-up assessments conducted three months after the office visit showed that a significantly greater proportion of intervention group patients had stopped using ST (32% of the intervention group participants versus 21% of control group patients, kappa 2 = 8.03, p less than .01). The intervention protocol is described in detail so that dental hygienists may adapt it for use in their practice.
