PURPOSE The objective of this study was to compare the effect of air abrasion (KCP 2000), acid etching (37% phosphoric acid), and the combination of both procedures on the shear bond strength and microleakage of a light-cured pit-and-fissure sealant to the enamel of human primary molar teeth. METHODS Noncarious extracted human primary molars were randomly divided into 4 groups in preparation ...

The use of sealants and sealant restorations has increased considerably over the past 10 years, and with it increased the problem of detecting secondary caries and marginal (micro)leakage. It was the purpose of this study to investigate the validity of electrical conductance measurements (ECMs) in diagnosing marginal leakage into dentine of sealants and sealant restorations. Ninety extracted pr...

objective: probable effect of fluoride containing materials like apf on sealants is very important. the purpose of this study is to assess the effect of frequent application of apf (1.23%) on the surface microhardness of two fissure sealants and one flowable composite.   methods: in this experimental study, 81 specimens of two fissure sealants and one flowable composite were prepared, using spe...

BACKGROUND The resin-based pit and fissure sealant is considered a successful tool in caries prevention, however there is a growing evidence of its use in controlling already established caries in posterior teeth. The aim of this clinical trial is to verify the efficacy of pit and fissure sealants in arresting dentinal caries lesions compared to partial excavation and restorative treatment in p...

OBJECTIVES This study assessed the cost effectiveness of a three-year school-based pit and fissure dental sealant and fluoride mouthrinsing program in two nonfluoridated regions in Victoria, Australia. METHODS The analysis was based on a community intervention in five schools comparing an intervention group receiving the pit and fissure dental sealant, a weekly fluoride mouthrinsing, and an a...

Title: Antibacterial properties of fluoride releasing glass Ionomer cements (GICs) and pit and fissure sealants on Streptococcus mutans. Background: Occlusal pit and fissures are the most susceptible sites for dental caries. The clinical effectiveness of GICs and fissure sealants in preventing caries is well-documented, but there is some concern about bacteria left beneath sealants. Objective: ...
