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

Study Overview
=================
Brief Summary
-----------------
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: Primary outcomes: To evaluate sealant retention, anticaries effect and marginal integration. Secondary outcomes: to evaluate, colour change and surface roughness of sealant.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| To evaluate sealant retention | Alpha - complete retention Bravo- partial retention Charlie- no retention | 9 months | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| To evaluate marginal integrity | Alpha- No visible evidence of a crevice along the margin of the sealant that the explorer could penetrate. Bravo- Visible evidence of a crevice along the margin of the sealant that the explorer could penetrate. | 9 months | 
| to evaluate anti caries effect | Alpha- Sound fissures. Bravo- Fissures with caries. | 9 months | 
| to evaluate colour change | Alpha- No discoloration anywhere on the margin around the sealant. Bravo- Visible partial discoloration the margin around sealant. Charlie- Visible discoloration on the margin around all sealant. | 9 months | 
| to evaluate surface roughness | Alpha- The sealant is similar to polished enamel. Bravo- The sealant surface is similar to composite material surface contained submicron filler. Charlie- The surface is rough that prevents the explorer movement along the surface. | 9 months |
