Abstract

Pit and fissure sealant placement is considered as an effective modality for prevention of caries on occlusal surface. Any deciduous or permanent tooth at risk of developing dental caries will benefit from the application of the sealant. The success of the sealant placement is directly related to the adequate knowledge of the mechanism of development of dental caries, with the knowledge and implementation of quality surface preparation of the enamel and with the appropriate adaptation of the sealant. Penetration, retention and marginal adaptation are the key factors in success of pit and fissure sealant restorations. The failure of the marginal adaptation leads to the marginal leakage, which means passage of bacteria, fluids, molecules or ions between enamel and the sealant, creating possibility for development of dental caries below the sealant.
