Sealants effectively arrest non-cavitated caries lesions on the fully erupted occlusal surface of permanent teeth. However, the clinical effectiveness of sealants is uncertain in preventing occlusal caries lesions in partially erupted permanent molars. This study aims to evaluate the progression of caries, the degree of retention, survival rate, and quality of the remnant after applying conventional total-etch resinous sealant and self-etch sealant in erupting molars.

Sealants retention
Sealant retention was assessed as follows: total retention of sealant on the occlusal surface or the partial or complete absence of the sealant on the occlusal surface.
