Abstract

STATEMENT OF PROBLEM:

Adequate plaque control is essential for the maintenance of a healthy oral mucosa. Denture cleansers are a popular method used by denture wearers for cleaning. The clinical effectiveness of a new cleanser in tablet form has not been tested in vivo. Methods used for the in vivo assessment of denture cleanser effectiveness are often not standardized.

PURPOSE:

The aims of this in vivo study were to develop a new method for assessing plaque levels on dentures by using digital imaging and to use this methodology, together with a validated visual scoring method, to evaluate plaque buildup on dentures.

MATERIAL AND METHODS:

Thirty-five subjects were randomized to 1 of 2 treatment groups: (1) dentures soaked in a new cleanser, or (2) dentures soaked in water. The treatment period lasted 14 days. Plaque was assessed at baseline and on days 2 and 14 by using digital image analysis and a visual scoring technique. Results were analyzed with ANOVA at the 95% confidence interval.

RESULTS:

The new cleanser showed a statistically significant reduction in mean visual plaque of 51% at day 2 (P = 0.0002) and 42% (P = 0.0014) at day 14 compared with water. Similar results were seen with digital imaging.

CONCLUSION:

The new denture cleanser proved to be effective at preventing plaque accumulation on dentures. The analysis of digital images gave similar results as the visual scoring method.
