Abstract :
Objective To compare the shear bond strength between fluoridated and non-fluoridated resin sealants.
Materials and Methods Fifteen human permanent molars were used. The teeth were sectioned equally in buccolingual direction and randomly assigned to fluoridated resin sealant (Helioseal F) and non-fluoridated resin sealant (Helioseal). After sealants were placed, the specimens were immersed in distilled water at 37 °C for 24 hours. Then, the shear bond strength was tested with the Instron Universal Testing Machine at a crosshead speed of 0.5 millimeter per minute and analyzed using paired T-test at 95 % confidence interval.
Results The mean and standard deviation of the shear bond strength of Helioseal F and Helioseal were 15.91 ± 5.18 and 15.52 ± 3.75 MPa. The difference was not statistically significant (p > 0.05).
Conclusion The shear bond strength of fluoridated resin sealant was not statistically significant different from non-fluoridated resin sealant
