Abstract
Objectives: This clinical study aimed to investigate if dentifrices containing policresulen would help to control dental plaque and gingivitis.
Methods: Seventy-eight eligible adults participated in this double-blind and randomized clinical study after an initial oral examination, calculus removal, and tooth prophylaxis. Two weeks after the procedure, the participants were assigned to three groups using the following dentifrices: (1) a dentifrice containing 0.22% NaF (control group); (2) a dentifrice containing 0.22% NaF and 100 ppm policresulen (policresulen group); and (3) a dentifrice containing 0.22% NaF, 100 ppm policresulen, and 1.00% bamboo salt (policresulen/bamboo group). The participants used only the provided dentifrice (for 1 min, twice a day, over 8 weeks) when brushing their teeth and followed their normal brushing habits. Dental plaque accumulation and gingivitis measurements were conducted using the Turesky modification of the Quigley- Hein plaque index (PI), the Loe and Silness gingival index (GI), and the percent bleeding on probing (%BOP) to obtain baseline data and 4- and 8-week data after grouping.
Results: A total of 73 participants aged 35.92±11.46 years (mean±SD) completed the study. The results after 8 weeks demonstrated statistically significant group-by-time interactions for PI, GI, and %BOP (P<0.001). The PI observed in the control groups increased over time up to 6%, while that observed in the dentifrice groups containing policresulen decreased by 5% (P<0.001). For GI and %BOP, the control group exhibited significantly higher values after 8 weeks, while the policresulen and the policresulen/ bamboo groups revealed similar index values as the baseline after 4 and 8 weeks. The changes in all indices were significantly different between the control and the two experimental groups. There were no significant differences in the results obtained from the policresulen/bamboo group and the results obtained from the policresulen group.
Conclusions: Use of dentifrices containing policresulen over 8 weeks demonstrated anti-plaque and anti-gingivitis efficacy compared to a control dentifrice.
