Aim: Aim of the present study was to evaluate the retention of a resin based sealant in primary and permanent teeth. Objectives of the study is to clinically evaluate the retention of a resin based sealant in primary, permanent molars and to compare the retention of the sealant placed using invasive and noninvasive techniques. Materials and Methods: The fissure sealants (DFS) were placed on all 200 primary second molars and permanent first molars in 68 children aged 3-8 years, using a split mouth design. A total of 200 FS were placed at baseline. Teeth were evaluated at 3 month, 6 month and 12 month period. The comparison of sealant retention in primary and permanent teeth at different intervals was d one w ith Freidman’s t est. Chiqure test was to use to compare between invasive and non-invasive techniques at different intervals. Results: There were statistically significant differences i n t he r etention r ates a t t he e nd o f 1 2 m onth between invasive and non-invasive techniques according to the Friedman’s test. The number of primary teeth showing complete retention at the end of 3 month, 6 month and 12 month are 90.8%, 84.7%, 83.7% respectively. The number of permanent teeth showing complete retention at the end of 3 month, 6 month and 12 month are 90.2% 87.3% & 82.4% respectively. Conclusion: On comparison of retention rates using invasive and non-invasive techniques for placement of sealant, invasive technique can be an effective t ool for increasing the retention of the sealant in permanent teeth.
