Comparative evaluation of microleakage of various restorative materials in pulpotomized primary molars - In Vitro study

Conventionally, stainless steel crown (SSC) is the preferred material for the restoration of pulpotomized primary molars. However, in situations where stainless steel cannot be used necessity for other restorative material arises.The aim of this study is to assess the microleakage of several coronal seal materials in pulpotomized primary molars- in vitro.Seventy-five primary molars were prepared with proximo-occlusal cavities. Restoration was done with Zinc oxide eugenol cement, SSC, composite resin, resin-modified glass-ionomer cement (GIC), and amalgam. Microleakage was assessed using dye penetration technique with stereomicroscope and scanning electron microscope.The Kruskal-Wallis and Mann-Whitney tests were used to statistically analyze the results.With regard to this present study composite resin and resin-modified GIC offers a good alternative for SSC.
