Direct pulp capping is the placement of a dental material directly over exposed pulp to prevent dental pulp from dying and avoid the need for root canal treatments. Calcium hydroxide and calcium silicates/mineral trioxide aggregates (MTA) have been commonly used for direct pulp capping with great success clinically. In recent years, resin-modified calcium hydroxide and calcium silicates have been developed with the advantages of precise placement, command set, and superior physical strength. As pulp capping materials would be in direct contact with the pulp, the cytotoxicity and biocompatibility is of particular importance in order to avoid pulp irritation and maintain pulp vitality. Therefore, this review article will summarize the cytotoxicity and biocompatibility of direct pulp capping materials, particularly resin-modified materials.

Physicochemical Properties and Dentin Bond Strength of a Tricalcium Silicate-Based Retrograde Material

et al. 2017

The aim of this study was to evaluate the physicochemical properties and the apical dentin bond strength of the tricalcium silicate-based Biodentine in comparison to white MTA and zinc oxide eugenol-based cement (ZOE). Setting time and radiopacity were evaluated according to ISO 6876:2012 specification. Final setting time, compressive strength and pH were also assessed. Material's bond strength to the apical root canal dentin was measured by the push-out assay. Data were analyzed by ANOVA and TukeyKrammer post-hoc test. Biodentine presented the shortest initial (16.2±1.48 min) and final setting time (35.4±5.55 min). Radiopacity of Biodentine (2.79±0.27 mmAl) does not agree with ISO 6876:2012 specifications. On the other hand, Biodentine showed higher compressive strength after 21 days (37.22±5.27 MPa) and higher dentin bond strength (11.2±2.16 MPa) in comparison to white MTA (27.68±3.56 MPa for compressive strength and 2.98±0.64 MPa for bond strength) (p<0.05). Both MTA and Biodentine produced an alkaline environment (approximately pH 10) (p>0.05) compared to ZOE (pH 7). It may be concluded that Biodentine exhibited faster setting, higher long-term compressive strength and bond strength to the apical dentin than MTA and ZOE.

“…MTA is characterized by very good marginal seal due to its excellent adaptation to the hard tissues, high compressive strength within the range of 70 MPa and insolubility in fluids [18,19,27,32]. Additionally, the study by Wilkoński et al [17] and Camilleri et al [32] reveal deposition of Ca-P complexes on the surface of MTA and formation of early forms of apatites in their presence. This has a favorable impact either on the processes of apexification or obtaining an adequate marginal seal.…”

“…It has been observed that dentinal bridges stimulated by MTA are formed more quickly and are thick, compact, homogenous, more regular in their structure and free of so-called tunnel effects which are typical with the use of calcium hydroxide [13,15,20,28]. MTA is characterized by very good marginal seal due to its excellent adaptation to the hard tissues, high compressive strength within the range of 70 MPa and insolubility in fluids [18,19,27,32]. Additionally, the study by Wilkoński et al [17] and Camilleri et al [32] reveal deposition of Ca-P complexes on the surface of MTA and formation of early forms of apatites in their presence.…”

A Comparison of Selected Regenerative Materials Used in the Management of Pulp Diseases – Review of the Literature

2015

View full text Add to dashboard Cite

The authors present a group of regenerative materials recommended for the treatment of deep caries, pulp exposure, endodontic treatment of immature teeth involving apexogenesis and apexification, and management of internal resorption and chronic periapical inflammations. Biomaterials which demonstrate biocompatibility, expressed by direct integration with dentine on a molecular level, also stimulate the formation of secondary and reparative dentine by odontoblasts. Calcium hydroxide is the oldest and has been the most widely used biomaterial since the 19 th century. However, due to some inconveniences experienced during treatment with this material, modern odontotropic materials like Mineral Trioxide Aggregate (MTA) or Biodentine are more frequently and more preferably used. New materials like MTA and Biodentine make it possible to develop new protocols of treatment and create opportunities for their successful results. Biodentine, in comparison with MTA, seems to be easier to prepare and apply, with a much shorter setting time. However it should be emphasized that observations of the performance of these new regenerative materials are relatively limited, so further research is required to confirm their long term performance and usefulness and to formulate reliable conclusions (Dent. Med. Probl. 2015, 52, 4, 485-490).

Characterization and analyses of acid‐extractable and leached trace elements in dental cements

Abstract: Dental materials based on tricalcium silicate cement and MTA Angelus release minimal quantities of trace elements when in contact with simulated body fluids. The results of acid extraction could be affected by nonspecific matrix effects by the cement.
