“…The volumetric loss of these materials may occur due to the loss of eugenol by a leaching effect (10). However, the present study showed that the volumetric reduction was low, probably because eugenol is not water-miscible (17). Although with lower values than Biodentine, MTA also had a decrease in volume after immersion (17).…”

“…However, the present study showed that the volumetric reduction was low, probably because eugenol is not water-miscible (17). Although with lower values than Biodentine, MTA also had a decrease in volume after immersion (17). The solubility of MTA was described with a decreasing rate, and its soluble fraction is mainly composed by calcium hydroxide, which is capable of maintaining a high pH in aqueous solution (23).…”

“…However, these tests can present some limitation once materials can present fluid caption, and the shrinkage or expansion can occur for all directions (16). Based on these limitations, micro-CT has been proposed as an alternative method to evaluate in 3D the physical changes after immersion in a fluid (7,10,11,17). Thus, based on volume changes the stability of the materials can be evaluated (7).…”

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 of this study was to assess the effect of different dimensions of test samples on volumetric change evaluation of different endodontic materials. AH Plus, FillCanal and Sealapex root canal sealers, Biodentine, IRM and MTA root-end filling cements were used in the tests. Samples of each material with a thickness of 1.5 mm and different diameters were manufactured: 6.3, 7.75, and 9.0 mm. The samples were scanned in micro-computed tomography (micro-CT) after setting and after 7 days of immersion in distilled water. The volumetric change was evaluated by means of the difference in the total volume of the specimens before and after immersion. Data were submitted to ANOVA and Tukey tests (p<0.05). The size of the samples did not affect the percentage of volumetric change of the materials (p>0.05). All sample sizes had greater volume loss for Sealapex among the sealers and Biodentine for the cements (p<0.05). In conclusion, Biodentine and Sealapex had the highest volume loss after immersion. Samples with 1.5 mm thickness, and diameters ranging between 6.3 and 9.0 mm can be used to assess the stability of endodontic materials using micro-CT without affecting the percentage of volumetric change.

“…Microcomputed tomography (micro-CT) has been used as a complementary tool to evaluate the solubility and dimensional stability of endodontic materials by the volumetric change analysis after immersion of the materials in a fluid [8][9][10] . Micro-CT analysis allows an accurate assessment 11 , and its use in high resolution allows analysis of microstructural characteristics 12 .…”

“…Micro-CT analysis allows an accurate assessment 11 , and its use in high resolution allows analysis of microstructural characteristics 12 . Moreover, due to its nondestructive characteristic, it is possible to analyze the same specimen over time 8,10 . In order to evaluate the volumetric change of materials by using micro-CT, cavities have been filled with the materials, decreasing the contact with the fluid to allow a methodology similar to the clinic condition 6,[8][9][10] .…”

Dental materials should be stable over time. This study investigated volumetric change of the root canal sealers AH Plus, Fill Canal, and Sealapex; and the root-end filling materials Biodentine, IRM, and MTA after different periods of immersion in distilled water. Resin models were manufactured with cavities 3 mm deep. The cavities were filled with the materials and scanned by microcomputed tomography after setting, and after 7 and 30 days immersed in distilled water. Percentages of volumetric changes after 7 and 30 days of immersion were compared by t-test. ANOVA/Tukey tests were used to compare endodontic materials (5% significance level). All root canal sealers had an increase in their volumetric change after 30 days. Among root-end filling materials, only IRM showed difference between the periods. Biodentine showed more volumetric changes than MTA, but both materials kept their volume from 7 to 30 days. In conclusion, the immersion period of endodontic materials may affect their stability.
