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...

To investigate the effectiveness of topical fluorides in preventing fissure caries, we conducted a randomized controlled trial with parallel groups. In total, 501 children (1,539 molars, 3,078 sites), mean age 9.1 years, who had at least one sound permanent first molar with deep fissures or fissures with signs of early caries were recruited. They were randomly allocated among four groups: (1) r...

BACKGROUND/AIM Retention of fissure sealants and good adaptation to enamel are essential for their success. Fluoride releasing resin-based materials are widely accepted for pit and fissure sealing, but newly designed glass ionomers can serve as a good alternative. The aim of this study was to evaluate microleakage and sealing ability in vitro, and to clinically assess two fluoride releasing fis...

Arresting occlusal enamel caries lesions with pit and fissure sealants The aim of this study was to evaluate the feasibility of pit and fissure sealants and the effectiveness of the two sealant methods applied in every-day practice in public dental health care in Finland. Two sealant methods were evaluated according to their effectiveness in preventing dentin caries at occlusal surfaces and sea...

AIM The aim of this study was to investigate the microleakage of pit and fissure sealants in primary teeth and to determine if multi-step methods should produce better results in terms of microleakage prevention. METHODS AND MATERIALS A total of 40 intact primary molars were randomly assigned to one of four sealant groups: resin based sealant Ultraseal XT (US - Ultradent) (Group 1, n=10); adh...
