Background. The aim of this study was to evaluate the effect of acidic, neutral and alkaline environments on the solubility of white mineral trioxide aggregate (WMTA) and Biodentine (BD). Methods. Thirty-nine ring molds were randomly divided into three groups of A, B, and C (n = 12) with pH values of 7.4, 4.4 and 10.4, respectively, and an empty mold was used as a control. Each group was further divided into two subgroups (1 and 2) according to the material studied. The samples in groups A, B and C were transferred into synthetic tissue fluid buffered at pH values of 7.4, 4.4 and 10.4, respectively, and kept in an incubator at 37°C with 100% humidity. Daily solubility at 1-, 2-, 5-, 14-, 21-, and 30-day intervals and cumulative solubility up to 5-, 14-, and 30-day intervals were calculated. Statistical analysis was carried out with independent-samples t-test, two-way ANOVA and post hoc Tukey tests using SPSS 18. Statistical significance was set at P<0.05. Results. Both WMTA and BD exhibited the highest solubility in acidic pH with 5.4235±0.1834 and 10.7516±0.0639 mean cumulative solubility values at 30-day interval, respectively. At all exposure times, BD was significantly more soluble than WMTA (P<0.001). Conclusion. Acidic periapical environment jeopardized the solubility of both WMTA and BD, affecting their sealing characteristics in clinical applications like perforation repair procedures and blunderbuss canals.

Introduction: Furcation perforation is one of the complications that occur during endodontic treatment due to anatomical differences or iatrogenic causes. Repairing the perforation with a biocompatible material eliminates the connection with the gingival sulcus and positively affects the prognosis. The sealing ability of the repair materials is very important and is affected by the conditions of the environment in which they are applied. Aim: To compare the sealing efficiency of Mineral Trioxide Aggregate (MTA) (Angelus, Londrina, PR, Brazil) and Biodentine (Septodont, Saint Maur des Fosses, France) materials used in the repair of furcation perforations in acidic and neutral environments. Materials and Methods: This in-vitro experimental study was carried out in the Department of Endodontics at Dicle University Faculty of Dentistry, Diyarbakır, Türkiye and Dicle University Science and Technology Application and Research Center from 10th June 2020 to 22nd July 2020. A total of 96 mandibular molars were used in the study. The specimens were randomly divided into two equal groups (n=48). When the perforations were repaired with MTA and Biodentine materials, each group was divided into four subgroups (n=12). These subgroups were kept in Phosphate Buffered Saline (PBS) and Acetic Acid (AA) solutions for different periods of time from 4 or 34 days, and all groups were immersed in methylene blue solution. The dye penetration level of the divided sections was examined under a stereomicroscope (Leica, Wetzlar, Germany). Microleakage data of all groups were statistically analysed using Kolmogorov Smirnov, Shapiro Wilk’s and Mann-Whitney U Test. Statistical significance was set at 0.05, it was stated that there was a significant difference when p-value <0.05. Results: The short-term (4 days) microleakage level of biodentine material in the AA environment was significantly lower than that of MTA material (p-value=0.005). There was no statistically significant difference between the materials in terms of long-term (34 days) microleakage levels in the AA environment (p-value >0.05). The long-term microleakage level in PBS environment of biodentine material was significantly lower than that of the AA environment (p-value=0.008). Conclusion: Lower microleakage levels were observed in the neutral environment than the acid environment with both MTA and biodentine during both holding periods.

The Impact

Recently, pre-mixed bioceramics in fast set formulations have been increasingly utilized in clinical practice as an alternative to mineral trioxide aggregate (MTA) for their shorter setting time and better handling properties. However, the impact on their osteogenic potential, due to modifications in chemical composition to promote a fast setting, is still unclear. This molecular and in vitro study compared the osteogenic potential of root repairing material putty fast set (FSP) with root-repairing material putty (RRMPU), root-repairing material paste (RRMPA), Biodentine™ and MTA. The null hypothesis tested was that there are no differences among the tricalcium silicate materials in terms of osteogenic potential. Standardized discs were cultured with MG-63 human osteoblastic-like cells to assess biocompatibility, the activity of alkaline phosphatase (ALP) and osteogenic potential. Biocompatibility was evaluated at baseline and after 24 and 48 h. Osteogenic differentiation was assessed after 15 days. Data were analyzed with one-way ANOVAs and Tukey’s post-hoc test (p < 0.05). All materials showed biocompatibility and bioactivity. ALP activity, which induces mineral nodule deposition, increased in all the cements tested, with a significant increase in RRMPU (p < 0.001) and FSP (p < 0.001) samples versus MTA. In vitro mineralization was significantly increased for RRMPU (p < 0.0001), FSP (p = 0.00012) and Biodentine™ (p < 0.0001) versus MTA. The bioceramics tested showed higher levels of biocompatibility and bioactivity than MTA; a higher capacity for mineralization was observed with RRMPU and FSP versus MTA.

Proposition: To evaluate the physical properties of flow and solubility of pure and improved mineral trioxide aggregate (MTA) cement with the addition of two plasticizing agents: sodium ether polycarboxylate and sodium naphthalene sulfonate at three different concentrations. Material and Methods: Flow and solubility tests were carried out using the established methodology recommended by the 57 ANSI/ADA and ISO 6876:2012 standards. Pure MTA was used as control group and was compared to the MTA containing sodium ether polycarboxylate and sodium naphthalene sulfonate at concentrations of 0.5%, 1.0% and 1.5%. Data were analyzed by one-way analysis of variance followed by a post-hoc Tukey test at a 5% significance level. Results: Sodium ether polycarboxylate increased the MTA flow at the three concentrations. The flow increased with increasing concentration (P<0.05). Sodium sulfonate naphthalene also facilitated flow, though it was inferior to sodium ether polycarboxylate. Sodium naphthalene sulfonate promoted a significant increase in the solubility of MTA (p=0.000). Conclusions: The additives improved the physical properties of MTA. Sodium ether polycarboxylate was found to be superior to sodium naphthalene sulfonate at all concentrations.

Aim & Objectives: The aim of this study was to evaluate the effects, at 24 h and 8 days, of 5% NaOCl and 17% EDTA on the Vicker’s microhardness of Mineral Trioxide Aggregate(MTA Angelus) (MTAA), Biodentine(Septodont, Saint Maur des Fosse’s France) and Pozzolan based endodontic cement named Endocem MTA(Maruchi, Wonju, Korea). Materials and method: Sixty samples of MTAA, Biodentine and Endocem MTA were tested for baseline microhardness at 24 h. They were divided into 12 subgroups (5% NaOCl or 17% EDTA, 24 h and 5% NaOCl or 17% EDTA at 8 days) and microhardness was evaluated at different time points. Results were recorded and analysed statistically via one-way ANOVA and Tukey’s post hoc  test. Results: MTAA had a higher baseline microhardness than both biodentine and Endocem MTA. At 24 hrs, the microhardness of all the materials was reduced by NaOCl and EDTA. At 8 days, NaOCl reduced the microhardness of MTA but that of Biodentine and Endocem MTA was increased. EDTA at 8 days, reduced the microhardness of both MTAA and Biodentine but an increase was seen with Endocem MTA. Conclusion: Changes in microhardness of MTAA, Biodentine and Pozzolan cement(Endocem MTA) were associated with the time for which the materials are allowed to set as well as the irrigating agent used,.

Abstract Objectives To assess tooth discoloration induced by different hydraulic calcium silicate-based cements (HCSCs), including effects of blood and placement method. Materials and methods Eighty bovine teeth cut to a length of 18 mm (crown 8 mm, root 10 mm) were randomly assigned to 10 groups (n = 8), receiving orthograde apical plug treatment (APT). Apical plugs were 4 mm in length and made of ProRoot MTA (Dentsply), Medcem MTA (Medcem), TotalFill BC RRM Fast Set Putty (Brasseler), or Medcem Medical Portland Cement (Medcem) plus bismuth oxide (Bi2O3) with and without bovine blood. Further, orthograde (with or without preoperative adhesive coronal dentin sealing) and retrograde APT were compared. Teeth were obturated with gutta-percha and sealer, sealed with composite and stored in distilled water. Tooth color was measured on apical plug, gutta-percha/sealer, and crown surface before treatment versus 24 h, 1, 3, 6, 12, and 24 months after treatment by spectrophotometry. Color difference (ΔE) values were calculated and analyzed by Shapiro–Wilk test, ANOVA with post hoc tests, Friedman test, t test, and post hoc tests with Bonferroni correction (α = .05). Results Tooth discoloration occurred in all groups with no significant differences between HCSCs (p > .05). After 24 months, color changes were prominent on roots but insignificant on crowns. Blood contamination induced a significantly decreased luminescence (p < .05). Blood had a stronger impact on tooth color than Bi2O3. No relevant effects of retrograde placement (p > .05) or preoperative dentin sealing (p > .05) were detected. Conclusions Apical plugs of the tested HCSCs cause discoloration of bovine roots, but not discoloration of bovine tooth crowns within a 24-month period. Clinical relevance APT should be performed carefully while avoiding direct contact with the coronal dentin, and in that case no aesthetic impairments occur.
