Background: Prevention of oral diseases is preferable to treatment and is the key method of achieving cost effectiveness for oral health improvement programs. The present study was conducted to determine the retention of pit and fissure sealants with different techniques. Materials & Methods: The present study was conducted on 60 patients of both genders. Patients were divided into 2 groups. In group I, mandibular permanent first molar of both sides was treated by acid etching alone and in group II, mandibular permanent second molar of both sides was pretreated by with air abrasion followed by acid etching. All patients were clinically determined after 3 and 6 months of sealant placement. Results: Out of 60 patients, males were 32 and females were 28. Completely retained sealants after 6 months was seen in 30 patients in group I and 28 in group II, partially in 15 in group I and 16 in group II and missing in 15 in group I and 16 in group II. The difference was non- significant (P> 0.05). Conclusion: Authors found no significant difference in retention of pit and fissure sealants in either of technique.
