Factors influencing the retention rate of resin-based pit and fissure sealants among primary school children- A randomised clinical trial

Background:

In modern dentistry, the focus is more on preventing caries than treating it, which helps preserve tooth structure. There is an approximately 50% prevalence of caries on the occlusal surface in school children. Pits and fissures with irregularities and invasions are responsible for this. In dentistry, to overcome these problems, different sealant technique is introduced, for instance, the conventional method, using a bur, using air abrasion, etc. Therefore, this clinical trial is designed to evaluate the retention rate of sealant using different application techniques.

Methodology:

The present Randomised clinical trail will include 50 children aged 6–9 from a primary school children based on inclusion and exclusion criteria. The contralateral 1st mandibular molar teeth will divided randomly before placing sealant with and without universal bonding agent and with and without deepening of fissures. after application of resin-based sealant evaluation will be done at 3, 6, 9 and 12 month interval respectively.
