Title Chlorhexidine Does not Reduce Caries Incidence In School-Based Programs Compared with Regular Fluoride Use and Oral Hygiene
Clinical Question In school-based programs with children and adolescents, is it more beneficial to use Chlorhexidine to prevent dental caries compared to fluoride treatment?
Clinical Bottom Line In school-based programs, repeated application of chlorhexidine does not lower the caries incidence in young individuals any more than regular fluoride use and oral hygiene practices. (See Comments on the CAT below)

(level of evidence)
#1) 18560640Ersin/2008149 eleven to thirteen year olds with high caries risk and low caries incidenceRandomized Clinical Trial
Key resultsParticipants were randomized into three different groups: chlorhexidine varnish, sodium fluoride gel, and dental health education programs. At the end of the two year study the caries increment, dental plaque scores, and salivary Streptococcus mutans counts were measured. The dental health education program group had higher Streptococcus mutans counts at the end of the study, but all three groups had similar plaque and caries values at the end of the study. Mean DMFS +/- standard deviation was 0.95 +/- 1.33, 0.88 +/- 1.47, and 1.05 +/- 2.01 in the chlorhexidine varnish, sodium fluoride gel, and education groups, respectively.

Comments on
The Evidence
All the subjects received initial and periodic education regarding oral hygiene. Fluoride gel showed the best results, but the difference was not significant. Researchers reported difficulties in patient compliance with the treatment plans.
Applicability This would apply loosely to any young patient at increased risk for caries, but more specifically to anyone planning an effective school-based program to reduce caries incidence among their students.
