"Comparative Clinical Evaluation of Pit and Fissure Sealants on Permanent First Molar Teeth in Children."

"Comparative Clinical Evaluation of Microfilled Resin Sealant, Nanofilled Resin Sealant and Flowable Composite as Sealant With Unfilled Resin Sealant on Permanent First Molar Teeth in Children."

Study was aimed to evaluate and compare clinical efficacy of the Microfilled resin sealant, Nanofilled resin sealant, Flowable composite as sealant, with Unfilled resin sealant on first permanent molar in children at 9 months follow ups.

Children (age 7 to 10) with deep pits and fissures, (ICDAS 0-2) included in the study and study was Split mouth randomized controlled clinical trial.

Sample size- Total number of 42 patients will be recruited in the study, with 42 first permanent molars in each group.

Methods-Patients were seated in supine position on the dental chair and cotton rolls will be applied for isolation. The first permanent molar in each group was treated as follows:

Group 1 -Intervention with Microfilled resin sealant. Group 2- ¬Intervention with Nanofilled resin sealant. Group 3 -Intervention with Flowable composite as sealant. Group 4 - ¬Intervention with Unfilled resin sealant. Patients and their parents were received instructions for daily brushing and oral hygiene maintenance. Sealant clinical efficacy was evaluated at 3, 6 and 9 month recall visit.

OUTCOME MEASURES:

1. Primary outcomes: To evaluate sealant retention, anticaries effect and marginal integration.
2. Secondary outcomes: to evaluate, colour change and surface roughness of sealant.
