Abstract: Introduction: Sealants used in pediatric dentistry provide a mechanical barrier in the anatomical pits and fissures thus, preventing dental decay.Aim: To compare the effectiveness of a glass ionomer and a resin-based fissure sealing material under four different contamination conditions. Materials and Methods:An in vitro study was carried out using 120 extracted mandibular molars which were randomly divided into 2 groups of 60 each, to be sealed with Glass ionomer sealant (GC Fuji Triage) and resin-based sealant (Clinpro™, 3M ESPE) respectively.The groups were further divided into 4 subgroups depending upon the contamination condition.The four different conditions were control (no contamination), water contamination, saliva contamination and saliva contamination followed by air drying.Sealant placement was done after respective contamination protocols and the teeth were further subjected to conditions simulating the oral environment.Each tooth was cut longitudinally into 3 sections which were examined under a stereomicroscope and analysed using UTHSCA image tool program.The findings were tabulated and subjected to statistical analysis. Results:The results revealed a significant difference between the sealant groups in the salivary contamination subgroup (p= 0.039).Intragroup comparisons in both Glass ionomer (p = 0.000) and Clinpro (p = 0.005) groups revealed significant difference within the four subgroups.Highest microleakage scores were obtained with the saliva-air drying condition for both the sealant groups.Conclusion: Salivary contamination followed by air drying leads to maximum microleakage in both the type of sealants.Clinpro performed better than Fuji VII under both contaminated and uncontaminated conditions.
