background and aims. newer curing units such as plasma arc can polymerize the sealants in much shorter curing times. the aim of this study was to compare the effect of two different curing units on the micro-leakage of a fissure sealant material. materials and methods. sixty two extracted premolars without caries were randomly divided into two groups of 31 samples. occlusal surfaces of all teet...

This study was performed to examine the success of a conservative cavity preparation using the principle of "sealing for prevention" rather than "extension for prevention." A total of 332 restorations were placed in 243 permanent molars in 114 children aged 6-14 with a mean age of 8 years. After 80 months, 104 restorations were examined for sealant retention, marginal staining, anatomic wear, m...

PURPOSE The purpose of this study was to assess the performance of sealants placed by senior dental students as part of a comprehensive dental care program that included periodic patient recall. METHODS The dental records of 100 patients ranging in age from 6 to 13 years were selected for review to determine the treatments provided for first permanent molars over time. Criteria for inclusion ...

Dear Editor, We read with interest the randomised clinical trial report by Hesse et al.1 concerning low-cost glass ionomer cement as ART sealant in permanent molars. In their Discussion, the authors state “... the choice of considering only fully retained sealants as successful is supported by the current theory that the complete clinical retention of sealant materials should be contemplated as...

Background. Wear resistance of pit and fissure sealant materials can influence their retention. Wear characteristics of sealant materials may determine scheduling of check-up visits. The aim of this study was to compare wear resistance of two flowable composite resins with that of posterior composite resin materials. Methods. Thirty-five disk-shaped specimens were prepared in 5 groups, includin...

This article reviews the scientific literature regarding pit and fissure sealants for oral health care professionals interested in managing dental caries. Review topics include the development of sealant materials; their efficacy and use with incipient caries; the use of sealants in combination with restorative materials and orthodontic care; the utilization patterns of sealants; and profession...

Objective: This in-vitro study evaluated the remineralizing effect of nano-pearl and nano-seashell incorporated into fluoride-based pits-and-fissures sealants by assessing enamel surface microhardness elemental analysis. Materials Methods: 75 extracted third molars were randomly allocated to one following 5 groups fluoride containing sealant: 10% nano-pearl; 15% nano-seashell; or plain sealant....

The penetration coefficients (PCs) and tensile bond strengths of eight pit and fissure sealant materials were determined. The PCs were tested at 22°C with five samples of each resin. Bond strengths were established in a tensile mode using an Instron * testing machine with 10 specimens for each sealant. Despite considerable variation in the PC values, all sealants showed similar tensile bond str...

Introduction: Fissure sealants have been widely used for more than four decades in preventing dental caries. Advances in technology have led to the development of moisture tolerant sealants. They are available as resin based and glass ionomer based. There is a paucity of studies on the effectiveness of moisture tolerant sealant materials in clinical conditions. AIM: The aim of the present study...
