Materials and Methods: 100 cavities (2 mm deep, 3 mm diameter) prepared in acrylic blocks were filled with silorane composite and subjected thermal cycle and divided into 5 groups (N=20). Group 1: Chlorhexidine; Group 2: Ozonated-water; Group 3: Nd:YAG-laser; Group 4: Er:YAG-laser; Group 5 (control): untreated. And disinfection method treated according to the groups. Composite repair procedure was implemented with the same silorane based composite. Groups divided into 2 subgroups (n=10). One of the subgroups for each group was subjected second thermal cycle. All of the samples tested by a universal test device. Data were statistically analyzed and significance test of the difference between the two means, the variance analysis, and Student-t Test used. Results: No statistical difference was observed among groups after first thermal cycle (p>0.05). After the composite repair, there were no statistically significant difference between groups that were subjected to second thermal cycle (p>0.05). When each group was evaluated in themselves on comparing before and after the thermal cycle after the repair operation; as no statistically significant difference between Ozonated-water, Nd:YAG, Er:YAG and Control groups (p>0.05), a statistically significant decrease was observed only in the Chlorhexidine group after thermal cycle (p<0.05). Conclusions: Ozonated-water, Nd:YAG-laser and Er:YAG-laser applications can be used in the repair of silorane-based composite restorations as an alternative antibacterial application, since the application of chlorhexidine reduces the repair bonding strength.
