Objective: To assess a multiple emission peak light-emitting-diode (LED) light-curing unit (LCU) by measuring the polymerization efficiency through the degree of conversion (DC) and Knoop microhardness (KH) of a resin-based pit and fissure sealant at various light curing times and two distances compared to a single emission peak LED LCU. Method: Sixty disks of a resin-based pit and fissure seal...

BACKGROUND/AIM Retention of fissure sealants and good adaptation to enamel are essential for their success. Fluoride releasing resin-based materials are widely accepted for pit and fissure sealing, but newly designed glass ionomers can serve as a good alternative. The aim of this study was to evaluate microleakage and sealing ability in vitro, and to clinically assess two fluoride releasing fis...

The aim of this study was to evaluate the preventive effectiveness of dry cow therapy based on antibiotic, internal teat sealant, and α-tocopherol administered separately or in various combinations at drying-off. The study was performed on 322 uninfected quarters of 95 cows originating from three dairy herds. The new intramammary infection rates after calving were measured to evaluate the effec...

The purpose of this study was to determine the combined retention rates of two Bis-GMA sealants ("Delton" and "Nuva-Seal") in a pedodontic clinic. Included in this study were 176 patients whose mean age was eleven years and five months. For all teeth examined, the relationship between the percentage of teeth with "sealant all present" and longevity is almost linear from the plotted value at six...

objectives: application of sealants is a safe and effective way to prevent occlusal caries in the posterior teeth. a successful sealant therapy depends on good isolation. decreased steps of adhesive application may enable proper isolation and use of self-adhering flowable composites for sealant therapy. this study sought to compare the marginal microleakage of fissure sealants and self-adhering...

PURPOSE The aim of this work is to study and compare the retention rate, caries-preventing and antibacterial effects of resin-modified glass ionomer and flowable composite in comparison to conventional fissure sealant. METHODS Forty-five children aged 7-10 years with newly erupted lower first permanent molars were randomly divided into three equal treatment groups. Group I: sealed by a conven...

OBJECTIVE To compare the penetration and adaptation of a moisture tolerant resin-based sealant with a conventional resin-based sealant in different occlusal fissure types in vitro by scanning electron microscopic (SEM) technique. METHODS Fifty sound, intact extracted premolars and third molars were included. They were randomly and equally allocated to receive either Seal-Rite (conventional re...

A variety of pit and fissure sealants are used clinically to protect the occlusal surfaces of teeth against dental caries. A new chemically activated bis-GMA type sea­ lant, Delton Pit and Fissure Sealant, has recently be­ come commercially available. The Delton Etching So­ lution supplied with the sealant contains 35 per cent orthophosphoric acid. The tensile bond strength of this sealant to e...
