Dental sealants and composite filling materials containing bisphenol-A (BPA) derivatives are increasingly used in children. The aim of this study was to evaluate the association between salivary BPA and the number of tooth surfaces filled with dental sealant, and to determine a cutoff BPA level. Salivary BPA concentration and the number of tooth surfaces filled with dental sealant/resin were de...

The objective of this study was to evaluate the safety and effectiveness of Adherus Dural Sealant when used as an adjunct to sutures in dural closure in a canine durotomy repair model. The effectiveness was evaluated at time of surgery, Day 8 and again at approximately 6 months by pressure testing. The safety and endurance of the test article was evaluated over approximately six months using ma...

Retention of fissure sealant in deep pits and fissures of molar is the main criteria for successful prevention of occurrence of dental caries. These fissure sealants are subjected to various factors like oral hygiene practices and dietary habit that differs from place to place. So a study was conducted to evaluate and compare the retention rate of the flowable composite resin sealant among the ...

A survey was conducted to identify and compare sealant knowledge and sources of sealant information of parents whose children had and had not received fissure sealants. The socioeconomic characteristics of these individuals were also compared. The sealant group was composed of the parents of children found to have a sealant on at least one permanent tooth during dental examinations of 2,036 ele...

Glass Carbomer is a new generation of restorative material developed from glass-ionomer cements with possibility of gradual mineralization into fluorapatite. The aim of this clinical trial was to investigate the retention of Glass Carbomer fissure sealant after 12 months, in comparison to a commonly used conventional resin-based sealant. Forty-eight teeth in 24 patients [mean (SD) = 8 (2.3) yea...

The purpose of this study is to compare the marginal leakage of two aesthetic cervical restorative materials viz the newly introduced light cured nano glass ionomer cement and nano ceramic composites, and also to evaluate the effect of unfilled resin sealant coating on marginal leakage of these aesthetic restorations. Thirty freshly extracted human upper premolars were used for the study. Class...

BACKGROUND A prolonged life of fissure sealant has always been the target for preventing caries in vulnerable newly erupted teeth. The use of preparatory techniques including bur introduction to the fissures is considered among such improving steps. MATERIALS AND METHODS Ninety freshly extracted healthy maxillary premolar teeth were randomly selected for this investigation. Teeth were then di...

Dear Editor, The use of fibrin sealant for parotid surgery without drains has been described as having cost saving benefits and obviating drain-related morbidities.1 It is known that the use of fibrin sealant in parotid surgery decreases drain output significantly, therefore allowing parotidectomies to be done with fibrin sealants but without drains.2,3 Until now, there has been no randomised c...

this paper investigates axial compression process of multi-layered tubes with circular cross-section under the axial loading in the quasi-static condition using experimental method. some specimens are prepared in seven different groups, namely; empty carbon/epoxy composite tubes, solid carbon/epoxy composite rods, empty copper tubes, composite tubes with silicon sealant filler, concentrically s...

OBJECTIVE Considering the minimally invasive approach to dentistry, the scientific community has focused on non-invasive treatments for caries lesions. The aim of this study was to evaluate the efficacy of a nonsurgical approach to arrest occlusal non-cavitated dentin lesions through glass ionomer sealing. METHODS In this controlled clinical trial, 51 teeth with clinically non-cavitated occlu...
