“…The current study showed that AH Plus presented the greatest volumetric stability. These results are in agreement with previous studies showing low volumetric changes for this sealer (7,10,11). Moreover, AH Plus was the only sealer that showed a volume increase.…”

“…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.

Introduction Flow and filling ability of root canal sealers are indispensable for hermetic sealing of the root canal. Micro-computed tomography (micro-CT) can be used as a complementary methodology to evaluate such properties. Objective To evaluate the flow and filling ability of AH Plus, Endofill and Sealapex by conventional methodology and micro-CT. Material and method The flow of the sealers was analyzed according to ISO 6876/2012 and complemented by the area evaluation. Glass plates were manufactured with diameters of 1×1×2 mm and 1×1×1 mm (length, width and height), with a central cavity and four grooves in the horizontal and vertical directions. Each material was placed in the central cavity. Another glass plate and a metal weight were placed on the cement and kept for 10 minutes. The glass plate/sealer set was scanned using micro-CT. The flow was calculated by linear measurement of the material in the grooves. The central filling (mm3) was calculated in the central cavity and the lateral filling was measured up to 2 mm from the central cavity. Data were submitted to ANOVA/Tukey tests (α=0.05). Result All evaluated sealers presented flow according to ISO 6876 standards. The materials showed central cavity filling capacity higher than 80% and lateral filling greater than 75%. There was no difference in flow (mm and mm2) and in the filling ability (mm3) provided by the materials (p>0.05). Conclusion All evaluated root canal sealers showed adequate flow and filling capacity, suggesting their clinical application.

“…Insolubility is a crucial feature in endodontic materials to provide intimate seal between tooth wall and restoration for subsequent successful root canal treatments (Torres et al 2019). Despite of the previously mentioned superior properties of MTA, their high solubility rate limits the clinical success rate of endodontic MTA (Espir et al 2016;Surya Raghavendra et al 2017).…”

Background: Insolubility is the main requirement for ideal root end filling material to provide perfect sealing ability. Moreover, alkalinity and bioactivity provide great chance for tissues healing and remineralization. So, the aim of this work was to evaluate the chemical composition, solubility, pH change, and calcium ion release of recently introduced commercial mineral trioxide aggregate (MTA) endodontic repair cement (Harvard, Universal HandMix MTA) compared with ProRoot MTA repair material. Methods: Solubility was evaluated after 7-and 14-day immersion time of specimens in phosphate buffer saline solution (PBS); the mean weight loss was evaluated and solubility was calculated as a percentage of the weight loss. For assessment of pH change and calcium ion release polyethylene tubes filled with the materials were soaked in distilled water for 7 and 14 days. Measurement of pH change was done by analytical pH meter. Concentrations of calcium ion release were measured using inductively coupled plasma optical emission spectroscopy. Data were statistically analyzed by independent sample t test and paired sample t test at 5% significance level. Results: Harvard MTA endodontic cement showed significant lower solubility and higher pH values compared with that of ProRoot MTA. ProRoot MTA exhibited significant higher calcium ion release value after 14 days (P value ≤ 0.05). Conclusion: Harvard, Universal HandMix MTA repair cement with its different chemical composition; exhibits a low solubility with enhanced alkaline pH value compared to ProRoot MTA repair material.
