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...

AIM The anatomical pits and fissures of the teeth have long been recognized as susceptible areas for the initiation of dental caries. The extreme vulnerability to decay of these pits and fissures on the occlusal surfaces has prompted dental scientists to seek methods of caries prevention. Motivated by the role of pit and fissure sealants in caries prevention, the aim of this study was to compar...

background pit-and-fissure sealants are safe and effective ways to prevent dental caries and are considered as a part of an overall caries-preventive strategy. dental caries are a public health problem and the most common intraoral disease affecting mankind. it is an infectious transmissible disease, with the child patient being at the highest risk. objectives the purpose of this study was to e...

F or adequate sealant retention, the bonding surface area must be maximized and the enamel clean, free of salivary contamination, and dry at the time of sealant placement.I, 2 However, because pit and fissure sealants bond to the cuspal incline planes and not to the bottoms of the pits and fissures,B_6 insufficient curing of the resin sealant could reduce the bond strength. The purpose of this ...

The purpose of this study was to examine the effect of thermal cycling on microleakage of a fissure sealant after it was bonded with different bonding agents and polymerized with different light curing units. To this end, two bonding agents (Xeno III, iBond), three light curing units (Astralis 3, Elipar free-light, Elipar free-light 2), and a fissure sealant (Fissurit FX) were used. Microleakag...
