Mineral trioxide aggregate and other bioactive endodontic cements: an updated overview – part I: vital pulp therapy

2017

Mineral trioxide aggregate (MTA) is a bioactive endodontic cement (BEC) mainly comprised of calcium and silicate elements. The cement was introduced by Torabinejad in the 1990s and has been approved by the Food and Drug Administration to be used in the United States in 1997. A number of new BECs have also been introduced to the market, including BioAggregate, Biodentine, BioRoot RCS, calcium-enriched mixture cement, Endo-CPM, Endocem, EndoSequence, EndoBinder, EndoSeal MTA, iRoot, MicroMega MTA, MTA Bio, MTA Fillapex, MTA Plus, NeoMTA Plus, OrthoMTA, Quick-Set, RetroMTA, Tech Biosealer and TheraCal LC. It has been claimed that these materials have properties similar to those of MTA without its drawbacks. In this article, the chemical composition and the application of MTA and other BECs for vital pulp therapy (VPT), including indirect pulp cap, direct pulp cap, partial pulpotomy, pulpotomy and partial pulpectomy, have been reviewed and compared. Based on selected keywords, all papers regarding chemical composition and VPT applications of BECs had been reviewed. Most of the materials had calcium and silicate in their composition. Instead of referring to the cements based on their chemical compositions, we suggest the term 'bioactive endodontic cements (BECs)', which seems more appropriate for these materials because, in spite of differences in their chemical compositions, bioactivity is a common property for all of them. Numerous articles were found regarding use of BECs as VPT agents for indirect and direct pulp capping, partial pulpotomy and cervical pulpotomy. Most of these investigations used MTA for VPT. In most studies, newly introduced materials have been compared to MTA. Some of the BECs have shown promising results; however, the number of their studies compared to investigations on MTA is limited. Most studies had several methodological shortcomings. Future investigations with rigorous methods and materials are needed.

“…Histologic sections were evaluated using light microscopy by 2 calibrated examiners, who were blinded to the material used in each sample. The sections were scored from 1 to 3 for calcific bridge formation, inflammation, and the presence of odontoblastic layer using criteria adapted from Long et al (21) and based on those of Asgary et al (22,23). Score 1 was described as being the worst score and 3 the best one.…”

Aim: To compare strontium ranelate as a pulp capping agent to bisphosphonate and calcium hydroxide. Materials and methods: The pulps of 36 premolars from 4 dogs were exposed and capped with one of 3 test materials, namely strontium ranelate, bisphosphonate, and calcium hydroxide. Half of the specimens underwent histologic evaluation at 6 weeks and the remaining half were assessed at 12 weeks. Each slide was scored from 1 to 3 according to hard tissue formation, inflammation, and odontoblastic differentiation. The pH of the 3 materials was also measured. Data were inspected using SPSS software and the recorded scores were statistically analyzed at 6 and 12 weeks. Results: Calcium hydroxide was the only material that exhibited discontinuous dentin bridge at both evaluation periods. Strontium ranelate showed irregular hard tissue formation in few of the samples at 12 weeks; while bishphonate did not induce any hard tissue formation. All the materials exhibited severe to moderate inflammatory reaction at 6 weeks which subsided to mild inflammation at 12 weeks. Differentiation of odontoblasts was observed with all materials at both evaluation periods with no significant differences among them. The average pH obtained for Dycal base was 9, and 12 for the catalyst; for bisphosphonate the value was 6.8; and 8.6 for strontium ranelate. Conclusions: Strontium ranelate was not as effective as calcium hydroxide as a pulp capping agent, while bisphosphonate failed to show any potential for hard tissue formation up to 12 weeks. However, all the test materials allowed healing of the pulp tissues.
