Background and Purpose: The objectives of the study were (1) to compare two techniques of sealant placement using Acid-etch technique and by using an Air abrasive technique, (2) to determine whether particular tooth locations are related to sealant loss or retention. Methodology: 30 children in age group 7-12 years were received sealant on non carious, non filled, occlusal, and buccal pit surfaces of both permanent first mandibular molars (36, 46) two in each subject of treatment groups: 1) Acid etch technique (Group A) and 2) Air abrasion without acid etch (Group B). A total of one hundred and twenty surfaces received sealants, and were evaluated at six months. Results: Rate of complete sealant retention at six months for occlusal surfaces were 89.29% for Acid etching and 78.57% for Air abrasion , and for buccal surface were 50% for Acid etching and 32.14% for Air abrasion. Conclusion: This study suggested that, rates of complete retention on the occlusal and buccal surfaces of both treatment groups were not significant. More research is needed to identify factors contributing to low retention rates on occlusal and buccal surfaces for Air abrasion technique.
