OBJECTIVE Long-term retention of pit and fissure sealants is crucial for their success. This clinical study evaluated the retention rate of a flowable composite resin (Filtek Supreme XT Flowable Restorative) compared to a conventional resin-based sealant (Concise Light Cure White Sealant) over 12 months. MATERIALS AND METHODS Forty subjects aged 6 to 9 years were included in the study. Using ...

BACKGROUND/AIMS We examined the association of fibrin sealant use with post-operative hemorrhage in patients who underwent a loop electrosurgical excision procedure (LEEP). METHODS We retrospectively collected clinicopathologic data of 344 patients who underwent LEEP at our institute between 2007 and 2009. We defined hemorrhage which occurred between 1 and 30 days after LEEP and required elec...

The purpose of this in vitro study was to evaluate microleakage of two fluoride-releasing sealants in saliva contaminated and non-contaminated conditions. Twenty-four human third molars were randomly assigned to two groups: saliva contaminated and saliva non-contaminated teeth. In the contaminated group, the teeth were contaminated with 0.02 ml artificial saliva for 20 seconds and blowed dry af...

The ability of uv light-cured fissure sealants to release fluoride ion from different concentrations of sodium fluoride (NaF), over a 3-week period was studied. Two hundred samples of sealant were prepared in which 1 group contained no fluoride (control) and 4 others contained NaF at 0.05, 0.2, 0.5, and 2% concentrations, respectively. The fluoride ion released by each sample after 1 day, 3 day...

OBJECTIVES The aim of this study was to compare the microleakage of a filled sealant with a drying agent (UltraSeal XT plus), a filled sealant (Prismashield) and an unfilled sealant (Delton), after conventional, bur, and air-abrasion tooth preparation techniques. SETTING The study was completed in a clinical setting at the Simulated Practice Environment Clinic, School of Dentistry, University...

BACKGROUND Pseudomeningocele is a known operative complication of Chiari decompression with significant morbidity. METHODS A retrospective analysis of 150 consecutive patients from November 1991 to June 2011 was conducted. Symptomatic pseudomeningocele was defined clinically; to meet definition it must have required operative intervention. Variables evaluated included sex, age, use of graft, ...

OBJECTIVE For skin defects caused by full-thickness burns, trauma, or tumor tissue excision, skin grafting is one of the most convenient and useful treatment methods. In this situation, graft fixation is important in skin grafting. This study was performed to compare the effectiveness of skin graft fixation between high-concentration fibrin sealant and sutures. There have been numerous studies ...

THE OBJECTIVE To examine whether audit and feedback could improve the quality of the application of dental sealant in rural Thai school children. RESEARCH DESIGN A single blind, cluster randomized controlled trial was conducted. CLINICAL SETTING Hospital-based and school-based school sealant applied by dental nurses in Southern province of Thailand. PARTICIPANTS Dental nurses and school c...

HYPOTHESIS Commercially produced fibrin sealant can be used to completely close both simple and complex fistulae in ano. METHODS A 29-patient prospective nonrandomized clinical trial was performed. In the operating room, the patient underwent an examination with anesthesia and the primary and secondary fistula tract openings were attempted to be identified. The fistula tract was curetted and ...

statement of problem: pit and fissure sealant therapy has been approved as an effective measure in the prevention of occlusal dental caries. resin based ma- terials are the most common materials used worldwide. a variety of resin based fissure sealants are produced and used. most of them have been presented with ideal results in research environment. however, their effectiveness in the real lif...
