AN INVITRO STUDY OF MICROLEAKAGE OF COMPOSITE RESINS WITH CHLORHEXIDINE CAVITY DISINFECTANT
Journal Title: Journal of Evidence Based Medicine and Healthcare - Year 2019, Vol 6, Issue 9
Abstract
BACKGROUND In routine dental practice, most of the patients want tooth colour restorations. Composite resin is a tooth colour restorative material. After removal of carious tooth structure, some microorganisms may remain in the cavity. To disinfect the cavity in this study chlorhexidine is used. Chlorhexidine is a broad-spectrum biocide effective against Gram +ve bacteria, Gram -ve bacteria and fungi. It is both bacteriostatic and bactericidal. Chlorhexidine kills microorganism by disrupting cell membrane. The aim of this study was to evaluate the effect of Rexidin (a chlorhexidine gluconate-based mouth wash) application on composite restorations micro leakage, using two adhesive systems: 3M ESPE single bond universal Adhesive and Adhese. MATERIALS AND METHODS In this experimental study, class V cavities were prepared on labial surfaces of seventy-two extracted human incisors. The specimens were randomly divided into 6 groups (n=12): A1: Acid Eching (AE), 3M ESPE single bond universal adhesive; A2: AE, Rexidin, blot drying, 3M ESPE single bond universal adhesive; A3: AE, Rexidin, water rinsing, 3M ESPE single bond universal adhesive; B1: AE (only enamel margin), Adhese; B2: AE (only enamel margin), Rexidin, blot drying, Adhese; B3: AE (only enamel margin), Rexidin, water rinsing, Adhese. Afterwards, the cavities were restored with 3M Z100 composite resin restorative, thermo-cycled (5 to 50°C, dwell time: 30s, 1000 cycles,), immersed in 0.5% methylene blue for 24 hours and the dye penetration was evaluated and scored on a scale of 0 to 4 under stereomicroscope (×30). The data was analysed using Kruskal-Wallis and Multiple Comparison tests. RESULTS Statistically significant difference was found between groups B1 and B2 at both occlusal and gingival margins. (P<0.05). CONCLUSION Rinsing off the cavity disinfectant (Rexidin) before the bonding procedure does not affect the seal at the resin-tooth interface when using either of the adhesive systems; however, the sealing ability of Adhese seems to be inhibited by the remnants of the disinfecting agent.
