We evaluated the concentration of fluoride release at the initial stage and after recharging the fluoride from a resin-based sealant containing surface reaction-type pre-reacted glass-ionomer (S-PRG) filler and conventional resin-based sealants. The concentration of other ions released from the sealants in the surrounding distilled water was also examined. At the initial stage, fluoride was rel...

AIM To assess the efficacy and safety of fibrin sealant for closure of mucosal penetration at the cardia during peroral endoscopic myotomy (POEM). METHODS Twenty-four patients who underwent POEM and experienced mucosal injury of the cardia during the procedure were retrospectively identified. Of the 24 patients, 21 had mucosal penetration and 3 had only slight mucosal damage without penetrati...

May/June 2002 This article focuses on the techniques used for successful pit and fissure sealant application by the dental assistant. Pit and fissure sealants first were utilized in 1967 and formally recognized by the American Dental Association in 1971. Since that time, many product developments have been introduced to increase their effectiveness and ease of use. Finding adequate time in the ...

A fluoride-containing sealant (FluroShield) was evaluated in vitro and compared to a sealant without fluoride (Helio-Seal). Both materials were applied to the occlusal surface of extracted teeth and microscopically evaluated for their ability to penetrate pits and fissures. Additional specimens were subjected to dye immersion and evaluated for resistance to microleakage. Disc-shaped samples of ...

This work deals with the design, the characterization and testing of a novel glass-ceramic to be used as sealant for planar solid oxide fuel cells and its compatibility with Mn1.5Co1.5O4 coated Crofer22APU. Thermal, sintering and crystallization behaviour and thermo mechanical properties of the sealant are reviewed and discussed, indicating therefore that these compositions can be deposited at ...

To study the performance of bitumen mixture pavement sealants from their micro-mechanisms, physical properties base bitumen, SBS-modified and epoxy resin sealant as well adhesive sealant-aggregate interfaces were studied using a molecular dynamics simulation. The adhesion sealant-pavement crack wall was contact angle test based on surface energy theory. results show that has excellent propertie...

INTRODUCTION/AIM To appraise the clinical literature in determining whether loss of complete sealant retention as surrogate endpoint is directly associated with caries occurrence on sealed teeth as its clinical endpoint and to apply the appraised evidence in testing the null-hypothesis that the retention/caries ratio between different types of sealant materials (resin and glass-ionomer cement) ...

PURPOSE To investigate the effect of intracameral injection of fibrin tissue sealant on the anterior segment structures in a rabbit model. METHODS One eye of 10 rabbits received an intracameral injection of fibrin tissue sealant with a thrombin concentration of 500 IU (TISSEEL), and the fellow eye received an intracameral injection of balanced salt solution as a control. The rabbits were foll...

PURPOSE As a national objective, 50% of US children are expected to have dental sealants on at least one permanent molar by the age of 14 years. The present study was conducted to estimate the prevalence of dental sealants among Alabama Medicaid children and to evaluate the characteristics of the sealant users and non-users so the potential barriers in meeting the year 2000/2010 sealant objecti...
