“…, Trope et al . , Wang ). In laboratory studies, it has been reported to have excellent biocompatibility and sealing ability, as well as being associated with desirable clinical outcomes when used for repair of perforations, vital pulp therapies, root‐end fillings and root fillings, and when used as an apical plug (Parirokh & Torabinejad , Torabinejad & Parirokh ).…”

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.

“…MTA and BC fast set putty belong to a calcium silicate-based group of materials. During the hydration reaction, endodontic bioceramics release Ca(OH) 2 , which interacts with phosphates in the tissue fluids to form hydroxyapatite and tag-like structures in dentin [40]. BC fast set putty is premixed by the manufacturer and has a more homogenous and smaller particle size than MTA.…”

Background: Intracanal medicaments can be used in various endodontic conditions including multiple visit endodontics after trauma or in regenerative endodontics. These medicaments should be removed from the root canal before the placement of the filling or repair material. The aim of the present study was to evaluate the effect of prior calcium hydroxide (Ca(OH) 2 ) and modified triple antibiotic paste (mTAP) placement on the push-out bond strength of TotalFill BC fast set putty (BC fast set putty) to root dentin when compared to mineral trioxide aggregate (MTA). Methods: The root canals of 45 extracted mandibular premolars were prepared to a standardized internal diameter (1.5 mm). The specimens were randomly assigned to 3 groups according to the intracanal medicament used: mTAP (a mixture of metronidazole, ciprofloxacin, and cefaclor), Ca(OH) 2 , and no intracanal medicament. After 1 week, the medicaments were removed, and the middle third of the roots were cut into two transverse sections (2.0 ± 0.05) (n = 90 slices). Thereafter, the specimens were divided into two subgroups (n = 45 each): MTA or BC putty. After 1 week, the push-out test was performed and failure mode was evaluated. The data were statistically analyzed using two-way ANOVA and Tukey's post hoc. Results: The application of the intracanal medicament did not significantly affect the bond strength of BC putty (p > .05). For MTA, the prior application of Ca(OH) 2 or mTAP significantly decreased the dislocation resistance (p < .05). Specimens in the MTA subgroups showed an almost equal number of cohesive and mixed types of failure while the majority of the specimens in the BC putty subgroups revealed the cohesive type. Conclusions: Ca(OH) 2 and mTAP promoted lower bond strength of MTA to root dentin compared to the control group. However, the BC fast set putty bond strength to dentin was not affected by prior medication with Ca(OH) 2 or mTAP.

“…When bioactive bioceramic materials come into contact with tissue fluids, they are believed to release calcium hydroxide and interact with phosphates, forming hydroxyapatite. Some of these materials, such as calcium silicate‐based cements (MTA), are considered the material of choice for endodontic treatment errors such as perforation repair, and also for root‐end filling or obturation of teeth with open apices . The possibility to “remineralize” the interface with bioceramic sealers is a tempting goal because both the strength and tightness of the interface could increase with time.…”

“…Although the role of MMPs in the degradation of dentin matrix in caries lesions had been sustained previously , the first direct evidence of this occurrence in non‐carious dentin matrix came when Pashley and co‐workers showed that acid‐etched dentin was gradually degraded in the absence of bacteria . Afterwards, a number of articles employing various techniques have confirmed that proteinases are present in human mineralized dentin and may become active after demineralization via a variety of methods .…”

Dentin is the largest substrate available whenever restorative procedures are implemented on the exposed crown or root of teeth. In endodontics, restorative/obturating procedures are practically restricted to dentin. It is well recognized that the incidence of fracture in endodontically treated teeth is intrinsically related to the amount of remaining dentin. Ideally, it is expected that a gap‐free, solid interface can be formed between the restorative/obturating materials and root dentin, providing an impervious seal and, simultaneously, fracture resistance to root‐filled teeth. Over the past years, a number of new obturating biomaterials have been launched in the market, bringing to endodontists the expectation of achieving consistent sealing/reinforcing of the root canal system. However, the successful sealing of root dentin remains one of the greatest challenges in restorative dentistry. This article will focus on reviewing some factors that affect the formation and integrity of dentin–biomaterial interfaces from the perspective of the dentin substrate. Because other articles in preceding issues of Endodontic Topics have already covered dentin structure and composition, the objective here is not to review these aspects. Specific attention is given, however, to depicting how chemical treatments affect existing root filling/restorative mechanisms and how some microbial and host‐related aspects can compromise the interaction of dentin with new biomaterials.
