Brushing and flossing alone, in the absence of rinsing with antiplaque agents, can in theory control plaque growth purely by mechanical removal action on the accumulated plaque. However in reality many patients do not achieve the desired professional goal of an adequate and consistent control of dental plaque. The study was planned to assess the effect of a mouthrinse containing Chlorhexidine (CHX) and amine/stannous fluoride (AmF) on plaque accumulation, gingivitis and salivary fluoride levels in comparison with two mouthrinses containing either essential oils (EO) or cetylpyridinium chloride (CPC) with sodium fluoride (NaF) in a teenage group. For this study 92 healthy teenage between 15 and 20 years were recruited for participation. The experimental gingivitis model consisted of a 2-weeks recruitment phase, followed by a 6-day rinsing period with one of the 4 mouthrinse formulations was used for the study. At the end of the pre-phase period and the rinsing period (Day-0/Day-6), gingival index (GI), plaque index (PI) and salivary fluoride levels were recorded. The statistical analyses were performed using Wilcoxon sign test and the dependent t test. A reduction in plaque re-growth was seen for the CHX+AmF formulation rinse, although there were no significant differences among all groups (p>0,001). During the experimental periods, the gingivitis indices increased significantly for all formulations (p<0,001), except for the CHX+AmF formulation. The CHX+AmF formulation scored higher levels of salivary fluoride at the end of the rinsing period (p>0,001). In conclusion, adding chlorhexidine mouth rinse to daily oral hygiene reduces bacterial plaque accumulation and improve the gingival index. Chlorhexidine mouth rinse appears to be more effective than the normal home care for improving the appearance of white spot lesions over a 3 months period.
