OLIVEIRA, Elias Pandonor Motcy de et al. Effectiveness of the temporary sealing of three restorative materials to the 50% silver nitrate solution. RSBO (Online) [online]. 2010, vol.7, n.1, pp. 73-77. ISSN 1984-5685.

INTRODUCTION AND OBJECTIVE: The aim of this study was to analyze three temporary restorative materials - Coltosol^®, Cavit^® W and Cimpat^® -, concerning their sealing capacity to the 50% silver nitrate solution. MATERIAL AND METHODS: 30 samples were divided into 3 experimental groups. Inside of each sample there was an antibiogram disc with 5 mm of diameter and 1 mm of depth, with 4 mm of one of the three sealing materials on it. After restorations, the samples were inserted into recipients with 50% silver nitrate solution, which were taken to the heater at 37ºC, where they remained for 7 days. Following this period and with the restorative materials removed, antibiogram disc analyses were performed, which were scored according to the leakage. RESULTS AND CONCLUSION: Data obtained were submitted to the Kruskal-Wallis non-parametric statistical test, with a level of significance of 5%. Results showed that Cimpat^® had the greatest levels of leakage, while Coltosol^® and Cavit^® W did not differ between themselves (p > 0.05).
