Objective: Residual bacteria under restorations can survive and proliferate even in the presence of a good seal. This can be prevented using adjunctive treatment with antibacterial agents during dentin bonding. However, its use can interfere with the bonding process. The current research was designed to study the influence of pretreatment with 2% chlorhexidine (CHX) gluconate (Consepsis), and ozonated water on shear bond strength, and microleakage of resin-modified glass ionomer cement (RMGIC) to primary tooth dentin. Materials and Methods: Thirty-six noncarious primary molars were selected, and the study was conducted in two parts as follows: evaluation of (1) Shear bond strength and (2) Microleakage. The teeth were randomly divided into three groups as follows: group I – Distilled water (control), Group II – 2% CHX gluconate, and Group III – ozonated water. The shear bond test was done using a Universal Testing Machine (Instron, USA). The results were analyzed using one-way ANOVA for multiple group comparisons and post hoc Tukey's for group-wise comparison. Microleakage was evaluated using stereo microscope. The results were statistically analyzed using the Chi-square test for group-wise comparison. Results: Bond strength was comparable across the three groups with distilled water showing the highest bond strength values followed by ozone group and 2% CHX group. CHX group showed significantly greater microleakage when compared with that of the ozone group. Interpretation and Conclusion: Ozonated water did not affect the shear bond strength or the sealing ability of RMGIC to primary tooth dentin, and hence is a viable option for cavity disinfection.
