Abstract :Objectives: This in vitro study was aimed to evaluate the effect of chlorhexidine digluconate (CHX) containing cavity disinfectant on microleakage of Class V self-adhesive resin-based composite restorations. Materials and Methods: Forty non-beveled Class V cavities (4x2x2mm) with occlusal and cervical margins on enamel were prepared on lingual and buccal surfaces of 20 molar teeth. Samples were randomly divided into 4 groups (n=10); and lingual cavities were disinfected with 2% CHX (Bisco). Cavities were restored using 2 different self-adhesive composites: Vertise Flow (Kerr); Activa BioACTIVE (Pulpdent) according to manufacturer’s instructions. Following 20 s polymerization with Valo (Ultradent) LED curing light, finishing and polishing were performed using Finishing Discs (Bisco). Teeth were coated with a nail polish excluding the restoration area and aged in distilled water at 24°C for 6 months. After immersion of the samples in 2% methylene blue solution, they were sectioned longitudinally in buccolingual direction with a diamond saw (Isomet 1000, Buehler). Microleakage on occlusal/gingival margins were scored under x8 and x20 magnification using a stereomicroscope (Leica MZ7.5). For statistical evaluation, Chi-square test was used. The significance level was set at p <0.05. Results: No statistically significant difference was detected between the total microleakage scores at occlusal and gingival margins (p=0.735; 0.944). Likewise, there was no significant difference between the gingival/occlusal margins of the restorations (p=0.216). CHX application did not show any statistically significance between microleakage values in Class V cavities restored with Vertise Flow or Activa BioACTIVE. (p=0.942; 0.577). Conclusions: CHX cavity disinfectant did not prevent microleakage in Class V cavities restored with self-adhesive composites.Keywords : biyoaktif materyal, kavite dezenfektanı, mikrosızıntı, self adeziv kompoizt, sınıf V kavite
