Effect of Different Dimensions of Test Samples on the Volumetric Change Assessment Of Endodontic Materials

Abstract New methodologies using micro-CT to evaluate solubility besides dimensional and morphological changes of endodontic materials are proposed. However, there is no standardization in the methods. The aim this study was assess effect different dimensions test samples on volumetric change evaluation materials. AH Plus, FillCanal Sealapex root canal sealers, Biodentine, IRM MTA root-end filling cements were used tests. Samples each material with a thickness 1.5 mm diameters manufactured: 6.3, 7.75, 9.0 mm. scanned micro-computed tomography (micro-CT) after setting 7 days immersion distilled water. evaluated by means difference total volume specimens before immersion. Data submitted ANOVA Tukey tests (p<0.05). size did not affect percentage (p>0.05). All sample sizes had greater loss for among sealers Biodentine In conclusion, highest thickness, ranging between 6.3 can be stability without affecting change.
