OBJECTIVE The efficacy of correctly applied fissure sealants has been revealed in the prevention of caries. Saliva and moisture contamination of the etched enamel surface before sealant placement can decrease the bonding strength of the sealant to the enamel. The aim of this study was to test the new bonding agents containing nano-fillers in order to reduce the negative effect of saliva contami...

OBJECTIVES Despite the increasing use of Internet, there is no supervision over the accuracy and quality of the information provided in the web. To deal with this problem, health specialists should take part in planning, publishing and supervision of online health-related information. The aim of this study was to evaluate the quality of information related to pit and fissure sealants in Persian...

Introduction: Sealing pits and fissures was introduced as an approach to prevent occlusal caries for more than two decades. The aim of this study was to compare the microleakage of flow able resin reinforced glass ionomer (Ionoseal) with other materials used as fissure sealants. Methods: In this in vitro study, 50 premolar teeth of human free of any caries were selected. Fissurotomy was done...

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...

RATIONALE Interlobar fissure integrity has previously correlated with responsiveness to endobronchial lung volume reduction therapy in patients with advanced emphysema. OBJECTIVE This report summarises the effect of interlobar fissure integrity on responses to treatment with a novel endoscopic tissue sealant (AeriSeal emphysematous lung sealant (ELS)) that collapses hyperinflated lung. METH...

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 ...
