Study Summary

Adult tooth decay is an infectious disease that afflicts the majority of Americans aged 55 and older and is the most common chronic disease at midlife with an ever growing economic toll. Despite the fact that specific bacteria cause tooth decay, no FDA-approved anti-microbial treatment for decay is available to the American dental professional. The Prevention of Adult Caries Study (PACS) is a study designed to evaluate the efficacy of a topical, temporary, 10% w/v chlorhexidine dental coating in reducing new decay in adult dental patients at risk for decay.

Primary Outcome

Study duration was too short to have progression from D2 (cavitated lesions) to D3 (cavitated lesions that involved dentin). D2 and D3 were treated equivalently for analysis. This measure is computed as the sum of weighted counts of transitions in tooth surface status (root and coronal surfaces combined) from randomization to the 13-month follow-up visit. Disease progression had a positive weight (e.g., S-to-D1 (sound to non-cavitated lesion) or D1-to-D2 (non-cavitated to cavitated lesion) = 1,
