Abstract Background and Aim: It has...
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...
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: Novel dental materials including nanocomposites have been introduced in recent years. It is claimed that they have superior properties such as high esthetic, low wear, increased filler content resulting in better mechanical properties, and releasing ions i.e. fluoride and amorphous calcium phosphate that are important for enamel remineralization. Considering these features, ...
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...
A variety of pit and fissure sealants are used clinically to protect the occlusal surfaces of teeth against dental caries. A new chemically activated bis-GMA type sea lant, Delton Pit and Fissure Sealant, has recently be come commercially available. The Delton Etching So lution supplied with the sealant contains 35 per cent orthophosphoric acid. The tensile bond strength of this sealant to e...
Objective: To compare the retention and marginal discoloration of Self-etch Total Etch Adhesive during Pit Fissure Sealant application at 1 month, 3 months, 6 12 months. Materials methods: 30 school-going children received sealants in all four permanent second molars, carried out Department Pedodontics Preventive Dentistry. The fully erupted molars were randomly allocated into groups: group A (...
Clinical trials were conducted on the teeth of 148 children to determine the effectiveness of a clearly visible white pit and fissure sealant. A three-year-follow-up study showed a high retention rate for the sealant.
