title: Effectiveness of methods used by dental professionals for the primary prevention of dental caries.
abstract: This paper summarizes and rates the evidence for the effectiveness of methods available to dental professionals for their use in the primary prevention of dental caries. It reviews operator-applied therapeutic agents or materials and patient counseling. Evidence of effectiveness is extracted from published systematic reviews. A search for articles since publication of these reviews was done to provide updates, and a systematic review of the caries-inhibiting effects of fluoride varnish in primary teeth is provided. Good evidence is available for the effectiveness of fluoride gel and varnish, chlorhexidine gel, and sealant when used to prevent caries in permanent teeth of children and adolescents. The evidence for effectiveness of fluoride varnish use in primary teeth, chlorhexidine varnish, and patient counseling is judged to be insufficient. Use of fluoride, chlorhexidine and sealant according to tested protocols and for the populations in which evidence of effect is available can be recommended. However, they may need to be used selectively. Estimates for the number of patients or tooth surfaces needed to treat to prevent a carious event suggest that the effects of these professional treatments are low in patients who are at reduced risk for dental caries. The literature on use of these preventive methods in individuals other than school-aged children needs expansion.
