Comparative evaluation of coronal sealing ability of light cure temporary restorative materials with conventional temporary restorative material using stereomicroscope

Abstract

Background: The coronal seal is a crucial factor in success of endodontic therapy. Hence the aim of the present study was to assess the sealing ability by evaluating microleakage of three different types of interim restorative materials. Method: A total of 80 extracted human premolars were divided randomly in to 4 groups. Group A: Control group, Group B: Systemp Inlay, Group C: Temp IT Blue, Group D: Cavit-G. Standardized access cavity preparation was done followed by placement of cotton pellet in the access cavity, Interim restorative materials were placed as per the assigned group of restorative materials. Teeth were stained with 2% methylene blue solution for 1 week after which all the teeth were analysed for dye penetration under stereomicroscope. Statistical analysis of data was done using one-way ANOVA and Post Hoc Tukey test with a significance level of P ≤ 0.05. Results: Systemp Inlay showed the least micro leakage value followed by Temp.it blu and Cavit G. Intergroup comparison showed statistically significant difference between Systemp Inlay and other groups whereas Temp IT Blue and Cavit G showed no statistical significance.

Coronal leakage of a new temporary restorative material: An invitro study

“…10 Methylene blue dye has been used in this study owing to its high-water solubility, ability to move by simple diffusion, resistant to absorption by hydroxyl apatite crystals present in dentin, and the molecular size of methylene blue dye is smaller than the size of bacteria. 11 To stimulate the oral conditions, the samples were placed in saline after cavity seal and to yield immediate hygroscopic expansion of the sealing material. 8 Here, in comparison with counter groups, Zinc oxide eugenol temporary restorative material showed more microleakage as the material showed less homogenisity due to the mixing of the powder and liquid components.…”
