Abstract :
Objective To compare microleakage between fluoridated and non-fluoridated resin sealants.
Materials and methods Thirty human upper permanent premolars were randomly assigned to fluoridated resin sealant (Helioseal F) and non-fluoridated resin sealant (Helioseal) groups of 15 each. Sealants were applied and specimens were immersed in distilled water at 37 °C for 24 hours before being subjected to thermocycling (5°-55°C, 30 second dwell time, 500 times). They were immersed in 1% methylene blue solution for 24 hours. The penetrating depth of dye in comparison to the sealant depth was measured by stereomicroscope at 40x magnification and analyzed with T-test at 95% confidence interval.
Results The mean and standard deviation of leakage of Helioseal F and Helioseal were 26.40 ± 31.29 and 36.33 ± 32.24 % of sealant depth. The difference was not statistically significant (p > 0.05).
Conclusion Microleakage of fluoridated resin sealant was not statistically significant different from non-fluoridated resin sealant.
