- Abstract
The control of dental plaque by chemical means can be a valuable auxiliary resource for individuals who have difficulties in performing dental plaque control through regular oral hygiene procedures. The aim of this study was to evaluate the effect of chlorhexidine and fluorine varnishes on the levels of Streptococcus mutans (S. mutans) present in the dental biofilm and on the dental plaque index. The study was carried out in a sample comprised thirty-nine schoolchildren between 13 and 15 years of age, distributed into 2 groups. Group I received a single layer of varnish with chlorhexidine and thymol on the maxillary right first molar. Group II received the application of varnish with fluoride following the same methodology. S. mutans count and dental plaque index recording were performed 7 days before the application and 7, 15 and 30 days after the treatment. It was observed that chlorhexidine and fluoride varnishes significantly reduced the number of S. mutans in dental plaque for 30 days (p<0.05). There was no difference between the varnishes. With regard to the dental plaque index, there was no alteration in any of the experimental time periods for both groups. It was concluded that varnishes, mainly those that contain fluoride, can be an interesting alternative for the prevention of dental caries in collective oral health programs.
