Texto completoThe aim of the study was to evaluate the radiopacity and subcutaneous tissue response of Portland cement (PC) with different concentrations of bismuth oxide (BO). PC was mixed with 0, 15, 20, 30 and 50% of BO determined in weight. The radiopacity was performed according to the ISO 6876/2001 standard for dental root canal sealing materials Statistical analysis was performed using ANOVA and Tukey-Kramer tests (p<0.05). For biocompatibility test, eighty-one albino rats (Rattus norvegicus) were selected. Two subcutaneous pockets were created in animal dorsum and polyethylene tubes filled with the cements were implanted. The rats were sacrificed at 15, 30 and 60 days after implantation. Histological evaluations were classified according to inflammatory response and repair process and scores were established. Statistical analysis was performed using the Kruskal-Wallis and Dunn tests (p<0.05). The results showed that there were statistical differences in radiopacity among PC with 50% of BO and all the other evaluated concentrations (p<0.05). Also, there was statistical difference between PC with 30% of BO and PC without BO (p<0.05). No statistical differences were found for inflammatory response in all the evaluated groups in each period (p>0.05). For repair process evaluation was observed a significant increase in fiber cellular tissue through the periods for all the groups (p<0.05). The tests suggested that 15 to 20% of BO added to PC attended ISO requirements for radiopacity. For biological response, there were decreases in the inflammatory response associated with an increase in the repair process, suggesting the lack of toxicity of BO added to PC.

Texto completoObjective: The purpose of this study was to investigate and compare chromatic alterations of an inorganic silicate-based cement, also known as white mineral trioxide aggregate (WMTA), submitted to different environmental conditions using the CIE L*a*b* system evaluated by two different methods. Methods: Twenty-four samples of WMTA (ProRoot® MTA, Dentsply Tulsa Dental, Johnson City, TN) were randomly distributed in four groups (n=4). In group 1 the samples did not undergo any additional treatment (negative control group). In group 2 WMTA samples were light irradiated for 60 seconds using a LED poliwave curing unit. In group 3 and 4 WMTA samples were coated with a layer of glycerine and adhesive, respectively and light irradiated for 60 seconds. A commercial spectrophotometer (VITA Easyshade® Advance 4.0, VidentTM, California, USA) and calibrated photographic digital analysis were used to determine colour coordinates from the CIE L*a*b* system of each sample after three different time points: 30 minutes, 48 hours and 7 days. In order to understand the chemical alterations associated to colour variations of the material x-ray diffraction analysis was also conducted. Data was analysed using statistical software IBM® SPSS® Statistics, version 20. Results: Consistency between the two colour measuring methods was not observed. Significant colour variation was observed for group 3. X-ray diffraction analysis showed no differences between compounds. Conclusion: WMTA showed significant dark discolouration after irradiation with an LED poliwave curing unit in an oxygen-free environment promoted by glycerine although after 48 hours discolouration had faded. The same light irradiation protocol associated to an oxygen-free conditions achieved by an adhesive resin layer did not induce significant discolouration at the end of the experiment protocol.
