Prevention of Adult Caries Study (PACS)

• Status: Completed
• Trial end date: 2010-06-01
• Target enrollment: 0
• Participant gender: All

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.
