Abstract

Objective: The purpose of this pilot study was to evaluate the effect of 1% chlorhexidine-1% thymol varnish (Cervitec®) on Streptococcus mutans (SM) and Lactobacillus spp. (LB) levels in patients with fixed orthodontic appliances. Material and methods: Twelve participants went through an intensive mode of application: chlorhexidine varnish was administrated 3 times within a 1 week period. Saliva samples for determination of SM and LB baseline levels were collected before the first varnish administration followed by sampling 1 and 2 months after the first varnish application. Results: A month after administration the group with high colonization levels (6 persons) exhibited reduction of SM and LB counts when compared with baseline levels. The group with low colonization levels (6 persons) exhibited no significant reduction. Two months after treatment a slight growth of SM and LB counts was recognized. Conclusion: That indicates a time period of chlorhexidine efficiency and a necessary schedule of varnish application.
