Indicated teeth were selected in all the four quadrants. Computer-generated random allocation of either one of four sealants to the tooth was done. Evaluation was done at 6-month intervals for 18 months using modified Simonsen\u2019s criteria. Intergroup comparison of retention of sealants and reapplication percentage was analysed using Pearson\u2019s Chi-square test.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>A total of 140 teeth were sealed. At 6-month evaluation, resin-based sealants showed significantly maximum retention (90.0%) and least retention by glass ionomer sealants (6.1%). At 18-month follow-up, resin-based sealants (66.7%) showed significantly higher retention followed by polyacid-modified resin (33.3%), resin-modified glass ionomer (6.1%) and glass ionomer sealants
