Comparative Evaluaton of Resin Based and Glass Ionomer Sealants-An Invitro Sem And Shear Bond Strength Study
Journal Title: IOSR Journal of Dental and Medical Sciences (IOSR-JDMS) - Year 2019, Vol 18, Issue 2
Abstract
Pit and fissure sealants are an indispensable part of preventive dentistry. They prevent occulsal caries by cutting off the nutrient supply to the bacteria in susceptible pits and fissures. Aim: The purpose of the study was to compare the flow and adaptation of Fuji VII (Glass ionomer based sealant) with Fissurit F (Resin based sealant) and also to evaluate the difference in the shear bond strengths of the same materials. Methodology: 40 premolars extracted for orthodontic reasons were used for this study and they were divided into 6 groups. After accomplishment of the different treatments 5 teeth from each group were observed under SEM for adaptation and flow of the sealant, and 10 teeth each were tested for shear bond strength of the materials. The specimens were submitted to thermocycling process and used for the evaluation of the variables. Results: It was found that Fuji VII fared a little better than Fissurit F, when comparing the flow and adaptation. Significant differences were found between the shear bond strength scores ,with Fuji VII scores being lower. Conclusion: Of the two sealants tested in this in vivo study, Fuji VII and Fissurit F , Fuji VII performed better in the flow and adaptation evaluation and Fissurit F performed better in the shear bond strength testing.
