STATEMENT OF THE PROBLEM Fissure sealant therapy is among the most effective methods of preventing dental caries. However, it is lengthy and isolation of the teeth is difficult in this procedure especially in young children. Using new hydrophilic fissure sealant may reduce such problems. PURPOSE This study aimed to evaluate the clinical success of a hydrophilic fissure sealant on the lower pe...

introduction: it was to compare the efficacy of semiannually fluoride varnish application versus pit and fissure sealant to reduce occlusal caries incidence. materials and methods: a randomized parallel designed study was conducted with 352 child-ren aged 6-7 years. participants were allocated into biannual application of varnish (n=179) (naf 5 %( durafluor, dentsply®, latin america) or resin-b...
Background and Aims: A large number of investigations have revealed that physical and chemical alterations and weight loss could occur in composite materials exposed to acidic phosphate fluoride (APF) gel. The purpose of this study was to assess the microleakage of a fissure sealant and a flow composite exposed to acidulated phosphate fluoride (APF) gel. Materials and Methods: In this in vitro...
effect of different enamel preparation methods on microleakage of fissure sealant: an in vitro study
objective: lack of a dental material with optimal adhesion and sealability is an important challenge in modern dentistry leading to marginal leakage. there are controversies on the necessity of enamel preparation in pit and fissure sealant therapy and its effect on decreasing the microleakage therefore, the present in vitro study aimed to assess the amount of microleakage with and without ename...
Background and Aims: Teaching of clinical skills is one of the most important aspects in training medical students. The aim of this study was to compare the effectiveness of videotaped and live demonstrations for applying fissure sealant on permanent molar teeth at Zahedan University of Medical Sciences (2010-2011). Materials and Methods: Thirty 8th-semester dental students were randomly assig...
Background and Aim: Since the clinical studies conducted to explore the effect of bonding agents on the success of fissure sealant are limited in number, the present study was conducted to compare the effects of two bonding agents on the success of fissure sealant of the saliva- contaminated teeth. Materials and Methods: In this study, 63 teeth of 35 students aged 6-8 with healthy and newly-er...
An investigation of pit and fissure sealant retention in 1,871 children in the Head Start program was conducted in Tennessee in September 1985 to determine the retention of the sealant after application to the occlusal surfaces of primary molars of 3- and 4-year-old children. The investigation shows pit and fissure sealants are retained on primary molars at a rate comparable to that expected on...
