Abstract

Background:  Dental amalgam has been used by dentists for more than a century. It has many advantages as a restorative material, because it has high strength, durable and easy to use. However, amalgam fillings have a number of drawbacks, such as, corrosion; they do not fulfill aesthetic demand; making undercuts for mechanical retention necessary, mercury toxicity and lack of adhesion to tooth structures. Recently popularity of resinbased composite restoration has increased than amalgam restoration because of its excellent aesthetic and other favourable characteristics. However, failure is also seen in composite restoration in posterior dentition as excessive wear, polymerization shrinkage, open inter proximal contacts, tooth sensitivity, secondary caries, irreversible pulpitis and restoration fracture. Aim of the study: To study microleakage in restorative materials used for primary teeth.  Materials and methods: The study was conducted in the Department of Pediatrics of the Dental institution. For the study, we collected 30 extracted non carious deciduous molars. The collected teeth were cleaned using hand instruments and were stored in normal saline solution at room temperature. The teeth were grouped into three groups, Group A, Group B, and Group C. We prepared class I cavities on the teeth using round bur, straight bur and inverted cone bur. The depth of the cavity was kept at 1.0-1.5 mm for all the teeth. The teeth were restored using manufacturer’s instruction. The teeth in group A were restored with colored compomer, in group B were restored with Giomer, and in group C were restored with resin modified glass ionomer cement.  Results: We observed that the highest frequency of score zero was seen in group B, followed by group A, and then group C. Score three was seen with one sample in group B.  Conclusion:  From the results of present study, this can be concluded that restoration of deciduous molars with colored compomer would be more long lasting because of minimal marginal leakage seen with the material.
