Description
Summary:•Antimicrobial photodynamic therapy prior to composite resin restoration does not increase microleakage.•Microleakage is significantly higher in the gingival walls independently of the application of photodynamic therapy.•Antimicrobial photodynamic therapy can be used for cavity disinfection without increasing the microleakage. Disinfection of enamel and dentin following cavity preparation is a necessity. Considering the possible effect of antimicrobial agents on tooth structure and dental adhesives, this study aimed to assess the microleakage of composite restorations following disinfection of cavity walls with antimicrobial photodynamic therapy (aPDT). Standard class V cavities were prepared in the buccal surfaces of 68 extracted human premolars. The teeth were then randomly divided into four groups (n = 17) for use of different adhesive systems (Adper Single Bond 2 or One-Step Plus) and disinfection with aPDT. The cavities were filled with Filtek Ultimate composite. After thermocycling and immersion in 0.5% fuchsine, the teeth were sectioned and evaluated under a stereomicroscope to determine the microleakage score. Data were analyzed using the Kruskal Wallis and Wilcoxon tests (P  0.05). In each study group, microleakage in the gingival wall was significantly higher than that in the occlusal wall (P
