“…This indicates that TheraCal can be used inside the canal and the cavity can be permanently restored immediately within the same session without requiring temporary filling material. Whereas, MTA shows a less initial compression strength & PBS and increasing its value required time and moisture ( 14 , 25 ).…”

“…The resin nature of TheraCal LC augments its compressive strength and bond strength to that confirms it as a beneficial pulp capping material. TheraCal LC is a promising pulp capping material since it can shorten the time and cost for both patients and dentists since allow positing the final restoration on the in the same visit ( 25 ). These results are in accordance with those of Alsubait et al .…”

Background One problem encountered in vital pulp therapy is the dislodgment of biomaterial as the result of the application of mechanical condensation forces for the final restoration of the cavity or occlusal loads. Material and Methods In this in vitro , experimental study, 90 dentin discs were prepared with Gates Glidden drills to have a 1.3 mm canal diameter. The specimens were divided into nine groups (n=10). ProRoot MTA, Biodentine, and TheraCal were applied in groups 1-3, 4-6, and 7-9, respectively. The PBS was measured after 15 minutes, four hours, and three days and mode of failure was determined. Results The interaction effect of time and material on PBS was statistically significant ( P <0.003). The PBS of Biodentine and ProRoot MTA significantly increased over time ( P =0.000). At 15 minutes and four hours, the PBS of TheraCal was higher than that of Biodentine and ProRoot MTA ( P =0.000). Our results showed the predominant type of bond failures in Biodentine and Theracal groups was cohesive, whereas it was adhesive for ProRootMTA. Conclusions Theracal showed higher values of bond strength than Biodentine and ProRootMTA at 15 minutes & four hours and may thus be better options for single session of VPT. Key words: Biodentine, Mineral Trioxide Aggregate, Pushout Bond Strength, TheraCal.

“…Thus, in this study, the solubility was measured by inserting the pastes in simulated canals. After, they were digitized in micro-CT to determine the volume of the paste in different periods of time, enabling the comparison of the volume lost over time 3,21 . High solubility is undesirable, as it interferes with the paste's direct contact with microorganisms 22,23 .…”

Aim: This study aimed to evaluate the pH, Ca2+ release, solubility, and antimicrobial activity of calcium hydroxide (Ca(OH)2) pastes in association with different substances. Methods: Sixty acrylic teeth (n=10) were filled with pastes that associated Ca(OH)2 with the following substances: benzalkonium chloride 5% (G1) and 50% (G2) both in propylene glycol, arnica glycolic extract (G3), green tea glycolic extract (G4), Calen/PMCC™ (G5), and Calen™ (G6). In the group G1 to G4 were used 1g of Ca(OH)2 powder with 0,8g of vehicle. pH and Ca2+ release was measured after 7, 15, and 30 days. For solubility, micro-CT was used immediately and at the periods of 7, 15, and 30 days. For the antimicrobial analysis, a biofilm of E. faecalis was induced in vitro on bovine dentin discs. Live/dead viability dye and confocal scanning microscopy were used. Results: The highest pH values occurred on the first 7 days, and the G6, G1, G3, and G5 presented the highest pH values at this period (P <0.05). Ca2+ release was higher in all groups at 7 days, with the highest values observed in G1, G5, and G6. The volume of all pastes showed no significant difference in the intragroup analysis at 7 and 15 days (P <0.05). G1 and G2 showed the highest antimicrobial action (P <0.05). For the biovolume, there was difference between the G6 and the other groups (P >0.05) with G1 presenting the lowest values. Conclusion: Benzalkonium chloride 5% increases the antimicrobial action of the Ca(OH2), without impairs physicochemical properties.

“…The management of deep caries, with exposed pulp, should be treated using direct pulp treatment [2] . Vital pulp therapy is designed to preserve and maintain pulp health in teeth that have been exposed to trauma, caries, restorative procedures or anatomical abnormalities [3] . Mineral Trioxide Aggregate (MTA) has been used in direct pulp treatment, with excellent clinical results reported, compared to the results of conventional use of calcium hydroxide [4] .…”

Introduction: Direct pulp treatment is a procedure in which the exposed vital pulp is treated with a therapeutic material, it is sought to promote healing, maintain pulp vitality and protect the pulp. Objective: To prove that TheraCal is the material of choice as a coating for direct pulp treatment in terms of biocompatibility and cytotoxicity, solubility and clinical management, effects on the pulp, clinical and radiographic success in comparison with current materials used; MTA and Biodentine. Methodology: An electronic search was performed during September 2021 in the PubMed-MEDLINE database. Human or In vitro comparative studies evaluating biocompatibility, clinical and radiographic success were included. No restriction was applied to the date of publication. Case series and expert opinions were excluded. Keywords such as "Theracal", "direct pulp capping", "Biodentine", "MTA" and "vital pulp treatment" were used. Results: Only one article was found that discussed the toxic effects of TheraCal. TheraCal has very favorable effects on the pulp, as it could be observed to induce dentin formation, these effects are to some extent limited. The solubility of TheraCal is one of its strongest characteristics, and it is very useful in indirect pulp capping, but not very useful in direct pulp capping. In comparison with other materials, Theracal shows good results that are considerably successful, however, the MTA and Biodentine variants present better percentages and higher probabilities of success. Conclusion: Theracal cannot be considered as a first-choice material when performing direct pulp treatment.
