Aims: The primary aim of this study is to evaluate and to compare the retention of two different pit and fissure sealants on permanent mandibular 1 st molar teeth.
Materials and methods: A total of 110 children aged between 6-9 years were selected. In each child, Aegis with amorphous calcium phosphate sealant was applied on the permanent mandibular 1 st molar of the right side while Delton the illuminating sealant was applied on the permanent mandibular 1 st molar of the left side, keeping the permanent maxillary 1 st molars as control. The treated teeth were evaluated for retention of sealants at 3, 6 and 12 months interval.
Statistical analysis used: The statistical analysis was performed using the Mann-Whitney U-test and Chi-square tests and Statistical Package for the Social Science version 15.0 statistical analysis software.
Result: The results were showed that retention and loss of sealant from the occlusal surfaces of the sealed teeth in both groups was maximum between 3 and 6 months.
Conclusion: Though statistically no significant difference was observed between the two groups, sealant with ACP showed better retention than the illuminating sealant.
