Abstract

Aim: This in vitro study evaluated the effect of different cavity disinfection agents on bond strength of a silorane-based resin composite. Materials and methods: Thirty-six caries-free human third mandibular molars sectioned in mesio-distal direction were mounted in acrylic resin with their flat dentin surfaces exposed. After the dentin surfaces were wet ground with # 600 silicon carbide paper, the teeth were randomly divided into 6 groups of 12 each according to the cavity disinfection agents; chlorhexidine (CHX); sodium hypochlorite (NaOCl), propolis, ozone, Er, Cr:YSGG laser and no treatment (control). After treatment of dentin surfaces with one of these cavity disinfection agents, Filtek Silorane adhesive system was applied. The silorane-based resin composite, Filtek Silorane was condensed into a mold and polymerized. After storage at 37°C for 24 hours, the specimens were tested in shear mode at a crosshead speed of 1.0 mm/minute. The results were analyzed by one-way ANOVA. Results: No statistically significant difference was observed between the groups (p>0.05). Conclusion: The use of the tested cavity disinfection agents, chlorhexidine, sodium hypochlorite, propolis, ozone and Er, Cr:YSGG laser did not significantly affect the dentin bond strength of a silorane-based resin composite, Filtek Silorane. Clinical significance: Cavity disinfectant applications did not affect the dentin bond strength of a silorane-based resin composite.
