Abstract

Purpose: The purpose of this study was to investigate the microleakage of a light cured, ormocer-based fissure sealant when photopolymerized with 2 different light emitting diode (LED) curing units and a conventional quartz-tungsten halogen (QTH) light- curing unit. Methods: Thirty freshly extracted, unerupted human third molars from 9 adolescent were randomly assigned into 3 groups (N=10/group). Pits and fissures were acid etched for 30 seconds, rinsed for 15 seconds with an air-water spray, and air-dried. An ormocer-based fissure sealant material (Admira Seal) was applied to all fissures. In group 1, the sealant was photopolymerized with a Smart Light LED curing unit (Dentsply) for 10 seconds. Another LED curing unit (Elipar II) and a conventional QTH curing unit (Hilux) were used in groups 2 and 3 for 10 and 30 seconds, respectively. Specimens were immersed in 0.5% basic fuchsin for 24 hours, sectioned and examined under a stereomicroscope, and scored for marginal microleakage. Results: Statistical analysis of microleakage scores revealed no significant difference among the groups tested (P>.05, Kruskal-Wallis test). Conclusion: The tested LED curing units may provide reduction in total application time without comprising marginal integrity of the ormocer-based sealant.
