INTRODUCTION: In recent years, the dental profession's focus has shifted from therapeutic to the preventive aspect of dental caries. Pit and fissure sealants, optimal fluoridation, healthy dietary habits, as well as good oral hygiene, have been recommended for caries prevention. Many sealant materials are being available in the market. Compomers are hybrid dental materials that are modified composite resins with polyacids. The aesthetic properties of the traditional composite systems are combined with fluoride releasing properties and adhesive properties of glass ionomer cement. Organically modified ceramic (Ormocer) material has high abrasion resistance and better aesthetics, similar to natural teeth. AIM OF THE STUDY: To compare the sealing ability of compomer and ormocer as pit and fissure sealants in permanent mandibular first molars of 7 -9 - year- old children. METHODOLOGY: A cross-sectional study with a split-mouth design was conducted on 88 children of 7-9 years of age who attended the Department of Pediatric and Preventive Dentistry. Children were selected based on the inclusion and exclusion criteria. By, tossing a coin, the placement of sealant material was selected for the right permanent mandibular first molar. Rubber dam isolation was done. The tooth surface was etched and washed. Respective sealants were applied. Sealants were cured with visible light and occlusion was checked with articulating paper. Subsequently, the second sealant was placed in the next appointment following the same clinical procedure in the opposite quadrant. Clinical evaluation was done at 3, 6, 9 months for retention, marginal integrity, color match, wear, and presence of caries. The criteria were graded and rated as alpha, beta, and charlie based on modified USPHS criteria. All the data were statistically analyzed using SPSS software 20. 0. RESULT: The retention of ormocer at the 9 th-month review interval was 88.3%, there was a statistically significant difference in retention rates of compomer and ormocer (p=0.003). The marginal integrity and wear of the ormocer at the 9th month review interval was 84.4% when compared with compomer and this was statistically significant with p=0.010. and p=0.035 respectively. Children with the least number of caries belonged to the ormocer group (p=0. 010) than the compomer. CONCLUSION: Children with ormocer as pit and fissure sealant showed good retention, remarkable marginal integrity, absence of wear, and dental caries when compared to compomer sealants. Hence ormocer based sealants can be used in pediatric dental practice to protect the children’s oral hygiene and to promote a healthy lifestyle.
