“…BioMTA shows similar composition to RetroMTA. Regarding RetroMTA, investigation in human teeth histologically showed disorganization of the pulp, dispersed mineralization, thin thickness of dentinal bridge in partial pulpotomies at eight weeks (13), and the new mineralized tissue did not exhibit regular dentin characteristics in direct pulp capping at seven months (14). However, these studies also reported good clinical/radiographic outcomes, which may be directly influenced by its physicochemical properties.…”

This study aimed to assess the physicochemical properties of a repair material in the Brazilian market, BioMTA, in comparison to other two materials currently in use (Biodentine and MTA Angelus). The initial setting time was evaluated using Gillmore needle. The pH was measured with a pH-meter after 24 h, 3, 7, 14 and 21 days. The radiopacity was determined using the equivalence in millimeters of aluminum (mm Al) from digitized occlusal radiographs. Solubility was determined after immersion in water for 7 days. The data were analyzed by one-way ANOVA and Tukey tests (a=0.05). The BioMTA initial setting time (5.2 min) was lower than the other materials (p<0.05). All materials showed an alkaline pH at 21 days. At 24 h, BioMTA was the most alkaline material (p<0.05); and at 3, 7, 14 and 21 days there was no difference between BioMTA and Biodentine (p>0.05), both being more alkaline than MTA Angelus (p<0.05). The radiopacity of BioMTA (4.2 mm Al) was significantly higher compared to Biodentine (p<0.05) and lower than MTA Angelus (p<0.05). The solubility of the materials was -4.2%, -1.6% and 4.1% for BioMTA, MTA Angelus and Biodentine, respectively, with a significant difference between them (p<0.05). Therefore, it can be concluded that BioMTA displayed a shorter setting time, an alkaline pH, a higher radiopacity, and a gain in mass.

“…RetroMTA (BioMTA, Seoul, Korea) is a new hydraulic bioceramic material proposed for use in similar indications as MTA (pulp capping, perforations and root resorption repair, apexyfication and apical surgery) [27][28][29]. According to the manufacturer's product specification, the pH of RetroMTA is initially 12.5, and decreased to 7.8-8 in 4 weeks [47].…”

“…However, unlike MTA, this material does not contain Portland cement. RetroMTA has fast setting time (initial time of setting 150seconds), good handling properties, no cell toxicity, setting reaction initiated by moisture, no heavy metals, and greater washout resistance [27][28][29].…”

Background: Calcium silicate-based cements (CSC), are self-setting hydraulic biomaterials widely used for reparative procedures in dentistry and endodontics. These materials possess bio-properties like biocompatibility, biointeractivity (release calcium (Ca2+ ) and hydroxyl (OH-) ions), and bioactivity (apatite-forming ability in contact with body fluids). Methods: Six calcium silicate-based materials were selected for this study: TheraCal LC (Bisco Inc. Schamburg, IL, USA), MTA Plus (Prevest Denpro, Jammu, India Avalon Biomed Inc, Bradenton, FL, USA), Biodentine (Septodont, Saint-Maur-des-Fossés, France), RetroMTA (BioMTA, Seoul, Korea), MTA Flow (Ultradent Products, Inc., South Jordan UT, USA), and OrthoMTA (BioMTA, Seoul, Korea). The pH was analysed immediately after immersion (baseline) and after 1 hour, 3 hours, 1 day, 2 days, 3 days, 1 week, 2 weeks, 3 weeks and 1 year with a pH meter, previously calibrated with solutions of known pH. To analyze the change in pH levels of the materials at each time point, 1- and 2-way analysis of variance, ANOVA followed by Tukey's multiple comparison test. The level of significance was set at p < 0.05. Results: Analysis of the tested materials showed statistically significant differences in terms of pH changes as a function of time showed a gradual rise in the pH of all materials. Conclusion: All tested materials exhibited continuous hydroxyl ion release resulting in a rise in pH until the end of time of experience. Because of the highly alkaline pH values of these materials, they possess biointeractivity properties.

“…In conjunction to vital signs, it supports that the pulp condition is healthy, leading to physiologic dentin deposition. Mass, E. et al reported that a calcified barrier was found in almost 70% of teeth [23], compared with 55%-64% in previous studies [24,25].…”

Traumatic human dental injuries involving the pulp might necessitate direct capping procedures. This clinical study aimed to analyse the histological outcomes using two different direct capping materials. Twenty patients with bilateral premolars, scheduled for orthodontic extraction, were selected. The teeth were treated either using ProRoot MTA or RetroMTA. All patients were recalled after 30 and 60 days for teeth extraction. The histopathologically stained specimens were blindly evaluated using hard tissue bridge formation, inflammatory reaction and pulpal findings criteria. Data were evaluated statistically. Results: After 60 days, only the parameter for hard tissue bridge formation showed significant difference in the ProRoot MTA group (p = 0.010), while both direct capping materials performed similarly regarding inflammatory pulp reaction and pulpal findings. Although, during the first 30 days, RetroMTA presented better results in terms of continuity, morphology, hard tissue bridge localisation, and extension/general state of the inflammatory reaction, the continuity was better at 60 days when ProRoot MTA was applied. Treatment with RetroMTA healed the pulpal tissue faster compared with ProRoot MTA but it seemed to be rather a reparative process.

Dental Pulp Response to RetroMTA after Partial Pulpotomy in Permanent Human Teeth

Abstract: This is the first work to evaluate a RetroMTA histologic outcome in partial pulpotomy in human permanent teeth. It shows pulp disorganization, an absence of inflammation, and discontinuous mineralization, which may represent a potential drawback with RetroMTA in this indication.
