The clinical effectiveness of a self-polymerized fissure sealant was studied, in 205 children, ages 6-10 years (mean age 71⁄2 years). There were 313 sites sealed and after four and six years, 247 and 115 were available for recall After four years, sealant retention was 73 % and effectiveness in caries reduction was 77%. After six years, 58% of sealants were retained and these were 56 % effectiv...

Retention of fissure sealant in deep pits and fissures of molar is the main criteria for successful prevention of occurrence of dental caries. These fissure sealants are subjected to various factors like oral hygiene practices and dietary habit that differs from place to place. So a study was conducted to evaluate and compare the retention rate of the flowable composite resin sealant among the ...

Glass Carbomer is a new generation of restorative material developed from glass-ionomer cements with possibility of gradual mineralization into fluorapatite. The aim of this clinical trial was to investigate the retention of Glass Carbomer fissure sealant after 12 months, in comparison to a commonly used conventional resin-based sealant. Forty-eight teeth in 24 patients [mean (SD) = 8 (2.3) yea...

BACKGROUND A prolonged life of fissure sealant has always been the target for preventing caries in vulnerable newly erupted teeth. The use of preparatory techniques including bur introduction to the fissures is considered among such improving steps. MATERIALS AND METHODS Ninety freshly extracted healthy maxillary premolar teeth were randomly selected for this investigation. Teeth were then di...

PURPOSE The purpose of this in vitro study was to determine the effect of different cleaning methods and the use of post-etching drying agents, as well as the influence of fissure types on the microleakage and penetration ability of fissure sealants. METHODS Ninety extracted human molar teeth were randomly divided into 9 groups of 10 each. The treatment groups were defined by the combination ...

The purpose of this study was to investigate the rate of fluoride release from an autopolymerizing fissure sealant containing various proportions of sodium fluoride. In the first phase, cured resin discs containing 0.00%, 0.1%, 0.25%, 1.0%, and 2.5% sodium fluoride were evaluated over a 180-day period. The second phase studied the release from the fissure sealant containing 2.5% sodium fluoride...

The purpose of this quantitative systematic review was to appraise the evidence on the caries-preventive effect of glass ionomer cement (GIC) in relation to resin-based fissure sealants. Nine English and two Portuguese databases were searched (15 January 2008). Randomized clinical trials and systematic reviews were considered for inclusion. Trial exclusion criteria were: drop-out rates > 33%; n...

OBJECTIVES The purpose of this in vitro study was to evaluate the microleakage and penetration of fissure sealant in permanent molar teeth with fluorosis after pretreatment of the occlusal surface. MATERIALS AND METHODS A total of 120 third molars with mild dental fluorosis were randomly divided into 6 groups (n = 20). The tooth surfaces were sealed with an unfilled resin fissure sealant (FS)...

This study evaluated the impact of extended etching and bonding strategies on the microshear bond strength of three sealant materials. Two pit-and-fissure sealants [FluroShield, Dentsply (light-cured) and AlphaSeal, DFL (self-cured)] and one light-cured flowable composite resin (Permaflo, Ultradent) were evaluated according to different enamel etching times (15 s or 30 s) and bonding procedures...
