BACKGROUND: The majority of the detected increment in dental caries is confined to pit and fissure surfaces of first molars. Application of pit and fissure sealants and topical fluorides are widely used procedures in the prevention of decay, and their effectiveness in caries prevention has been proved by systematic reviews. OBJECTIVES: The objective of this study was to compare the effectiveness of pit and fissure sealants with fluoride varnishes in the prevention of dental decay on occlusal surfaces. SEARCH STRATEGY: Electronic searching was performed on the following databases: the Cochrane Oral Health Group's Trials Register (last update November 2005), the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2005, Issue 4), MEDLINE (from 1966 to December 2005), EMBASE (from 1974 to November 2004), SIGLE (from 1976 to December 2004), SCISEARCH, CAplus, INSPEC, JICST-EPLUS, NTIS, PASCAL (last update December 2004), DARE, NHS EED and HTA (last update November 2005). Reference lists from articles that fulfilled the inclusion criteria in this review and from review articles based on the search of MEDLINE were searched for additional relevant articles. Conference abstracts published as books or journals and handsearched by the Cochrane Oral Health Group were also included. SELECTION CRITERIA: The inclusion criteria for study selection were: random or quasi-random allocation study design; sealants versus fluoride varnish or sealants and fluoride varnish...
