Comparative Evaluation of Sealing Ability, Water Absorption, and Solubility of Three Temporary Restorative Materials: An in vitro Study.
BACKGROUND: The quality of the coronal seal of root canal filling material is important for periapical health. Absorption of water or saliva by the temporary restorative materials leads to dimensional changes, loss of retention, staining and breaking in margin contours. Hence this study was carried out to evaluate and compare the sealing properties, water absorption and solubility of IRM (intermediate restorative material), Cavit G and GC Caviton.
STUDY DESIGN: Experimental, in vitro intergroup randomized control trial.
MATERIAL AND METHODS: 36 non carious premolars were randomly selected assigned to three groups, 12 teeth in each. Standard endodontic access cavities of approximately 4x4mm wide were prepared followed by the root canal obturation with Gutta-percha and restoration with experimental materials. For microleakage testing dye penetration method was used with 2% methylene blue dye. Followed by evaluation and scoring under stereomicroscope at 40x magnification. Disc shaped 12 specimens for each group were prepared for each material, stored in desiccator at 37° C, weighed daily to verify mass stabilization (dry mass,m1). Thereafter, the specimens were stored in distilled water at 37°C for 7days to obtain the mass after saturation with water (m2). The specimens were placed in the desiccators again, at 37° C, and reweighed until a constant dry mass is obtained (m3). Water absorption (WS) and solubility (SL) was determined by using the formulas, WS = m3 - m2/V and SL= ml - m3/ V.
RESULTS: GC Caviton showed least microleakage and least water absorption followed by IRM and Cavit G, the differences were statistically highly significant ( p < 0.001) and there was no statistical difference found in all the groups with respect to solubility.
CONCLUSIONS: GC Caviton is best and suitable temporary restorative material in endodontic interappointments followed by IRM and Cavit G.
