Abstract :Aim: The aim of this study was to evaluate the effects of silver diamine fluoride and diode laser applications used for desensitization on microleakage and colour change in the restorations of class V cavities. Materials and Methods: Twenty human molar teeth were used in this study. ClassV cavities (4x3x3 mm) (n=10) were prepared on the buccal and lingual surfaces. All teeth were divided into 4 groups according to the treatment methods for DH. Group 1 (silver diamine fluoride), Group 2 (940 nm diode laser), Group 3 (940 nm diode laser + silver diamine flouride), Group 4 (no treatment). All cavities were restored with nano-hybrid composite resin. Restorations were polished with discs. Colour changes were measured with a spectrophotometer on 1, 7, 14, 28 days. Colour change was calculated with the CIEDE2000 formula. To evaluate microleakage scores, samples were stained with 0.2% RhodamineB dye and cut bucco-lingually. Dye penetration was scored under a stereomicroscope. Data were statistically analyzed using the Shapiro-Wilks and Tukey HSD test at a 5% significance level. Results: According to the colour changes, a statistically significant difference was found between Group 1 and Group 3. In Group 2, there was significantly difference between 1-7 and 1-14 days, 1-7 and 1-28 days. The highest microleakage scores were obtained with the laser-used groups. Conclusion: Despite the use of a solution containing potassium, a colour change above the clinically acceptable threshold was observed in silver diamine used groups. Also, laser used groups have shown unacceptable colour change values.
