Abstract :Aim: The aim of this study was to evaluate the clinical success and the sealing ability of a resin based fissure sealant that applied enamel surface which was etched with conventional phosphoric acid and Er:YAG laser at different energy levels. Material and Methods: The study consisted of two parts; the evaluation of retention, marginal discoloration, marginal integrity and new caries formation for the clinical success after the treatment at 3, 6, 12 months; the evaluation of microleakage and penetration depth to fissures using dye penetration test. The in vivo part of the study was the surface preparation processes, 72 teeth in each group; It consists of 32% phosphoric Acid, Er:YAG laser- MSP insert ignore into journalissuearticles values(Medium Short Pulse); and Er:YAG laser- QSP insert ignore into journalissuearticles values(Quantum Square Pulse);. A total of 45 impacted human third molar teeth were used for in vitro part. Data were analyzed using SPSS 21. Results: The relationship between the success rates of 12-month clinical follow-up of fissure sealants and age, gender, and localization was assessed and there was no statistically significant correlation. When all criteria were considered, the most successful group was QSP. All the groups demonstrated microleakage regardless of the surface preparation techniques. However, there was no statistically significant difference between the groups. Conclusion: It is considered to determine the optimal energy level of laser will increase the clinical success.
