Background and Aim: Application of disinfectants in pits and fissures is a commonly used method to lower the cariogenic bacterial count in teeth. This study compared the effect of applying chlorhexidine on microleakage of pit and fissure sealant therapy using two adhesive systems.
Materials and Methods: In this in vitro study, 60 extracted molar teeth were randomly assigned to four groups (n=15): control group 1 (etch-and-rinse adhesive), control group 2 (self-etch adhesive), group 3 (etch-and-rinse adhesive and 0.2% chlorhexidine), and group 4 (self-etch adhesive and 0.2% chlorhexidine). After applying the sealant and subjecting the teeth to thermocycling, the teeth were immersed in 5% methylene blue solution. The teeth were sectioned into four parts and the dye penetration depth was measured under a stereomicroscope. Data were analyzed by the Mann–Whitney and Kruskal–Wallis tests using SPSS 24 (alpha=0.05).
Results: Microleakage was significantly lower in the self-etch adhesive system compared to the etch-and-rinse system in the control groups (P<0.05). For the etch-and-rinse adhesive, there was no significant difference in microleakage between the two groups with chlorhexidine (1.67±1.11) and without chlorhexidine (1.33±0.81) (P>0.05). Similarly, in the self-etch adhesive, microleakage did not significantly differ between groups with chlorhexidine (1.07±0.45) and without chlorhexidine (1.07±0.70) (P>0.05). The interaction effect of adhesive type and chlorhexidine on microleakage was not significant (P=0.428).
Conclusion: Application of chlorhexidine with both self-etch and etch-and-rinse adhesive systems did not significantly affect the microleakage of fissure sealant therapy. Chlorhexidine may be used under fissure sealants for its antimicrobial effects without increasing microleakage.
