“…Selecting the combination of calcium aluminate and tricalcium silicate is based on the high biological, mechanical and physical properties of both materials which could produce eventually a competitor product. Calcium aluminate a high mechanical resistance [9], a good setting time, and a rapid hydration rate classified as a hydraulic binder, act as a barrier preventing bacterial microleakage, has the ability to induce in situ hydroxyapatite generation since its chemical composition and thermal expansion coefficient are similar to those of teeth and human bones [10,23,24]. While silicate-based hydraulic cements are bioactivity materials.…”

“…Calcium aluminate shows excellent rheological characteristic, a high mechanical resistance, a good setting time, and a rapid hydration rate [9]. Calcium aluminate cement is classified as a hydraulic binder and it is also used for perforations repair and for bone defects filling [10]. It has high mechanical strength and the ability to form an intimate bond to the opposing tissues.…”

Objective: Endodontic perforation is a challenging mishap that should be repaired with a biocompatible material, Mineral trioxide aggregate (MTA) and Biodentine are the most commonly used repair materials. However, these materials are expensive, (MTA) has prolonged setting time and difficult manipulation. The purpose of this study is to prepare the experimental nano calcium-aluminate/tri-calcium-silicate (CA/C 3 S) material and comparing its physical properties with biodentine and MTA, to evaluate the experimental material eligibility to compete the commercial repair materials. And to perform part two (animal study) that will evaluate the cytotoxicity, the biocompatibility and the efficacy of (CA/C 3 S) in furcal perforation repair compared to diode laser. Material and Methods: A mixture of calcium carbonate and aluminum oxide was used to formulate calcium aluminate phase (CA), tri-calcium-Silicate phase (C 3 S) was formulated by firing of calcium carbonate and quartz. The produced powders were investigated by X-ray diffraction, then (CA) and (C 3 S) mixed with water.(CA/ C 3 S) compared with MTA and biodentine for setting-time, micro-hardness, dimensional-stability and solubility. Results: Mean setting time of (CA/C 3 S) was (32.70±0.75min) which is significantly higher than MTA and Biodentine. The Mean microhardness of (CA/C 3 S) was (56.50±7.41VHN) which has no statical difference with MTA and Biodentine. Solubility results showed weight increase for (CA/C 3 S) as following (6.29±3.05)and loss of weight for MTA and Biodentine. The percentage of change in dimensions for(CA/C 3 S) increased as following (0.64±0.78) while decreased for MTA and Biodentine. Conclusion:The experimental (CA/C 3 S) material showed good microhardness, dimensional stability and acceptable setting time that could be improved in further work.

“…Less radiopaque powder is required when barium or strontium cement phases are used for their higher atomic number of strontium compared to calcium. 173 When it comes to setting requirements, dentists are accustomed to using polymeric products which have "command setting" using a blue light, a quick-setting chemical reaction setting mechanism, or a combination thereof to have setting occur within seconds to a few minutes. For the quick-setting materials, the depth of cure is used to judge setting in ISO 4049.…”

Calcium silicate and calcium aluminate cements for dentistry reviewed

et al. 2021

Calcium silicate cements were identified as excellent materials for dentistry, particularly for dental procedures contacting the dental pulp or root system. Both calcium silicate and calcium aluminate cements cause the biomineralization (precipitation of hydroxyapatite [HA] phenomena and shield dental tissues from the underlying cement (a foreign body material). The cements also elute ions to stimulate cytokines that contribute to the healing of the dental pulp or in the tissue surrounding the root of a tooth. The cements serve as a foundation for other dental restorative materials. This paper reviews the cement phases, properties, in vivo reactions, and clinical benefits from the use of calcium silicate and calcium aluminate ceramic cements.

“…Among the bioactive metals, strontium ions (Sr 2+ ) offer the best responses to the body in terms of bone regeneration [ 106 ]. Strontium’s application as an additive in bone cements is recommended because it is a therapeutic component for treating osteoporosis [ 96 ], in addition to absorbing greater amounts of X-rays than Ca, making the material more radiopaque [ 24 , 105 ].…”

“…For example, radiopacity is an important physical property that most bioceramics intended for orthopedics and dentistry must have. It enables the clinical evaluation of these materials at the surgical site [ 24 ]. The application of radiopaque bioceramics is indispensable in areas where radiographic visualization procedures and detecting medical devices in soft and hard tissues are challenging.…”

Radiopacity is sometimes an essential characteristic of biomaterials that can help clinicians perform follow-ups during pre- and post-interventional radiological imaging. Due to their chemical composition and structure, most bioceramics are inherently radiopaque but can still be doped/mixed with radiopacifiers to increase their visualization during or after medical procedures. The radiopacifiers are frequently heavy elements of the periodic table, such as Bi, Zr, Sr, Ba, Ta, Zn, Y, etc., or their relevant compounds that can confer enhanced radiopacity. Radiopaque bioceramics are also intriguing additives for biopolymers and hybrids, which are extensively researched and developed nowadays for various biomedical setups. The present work aims to provide an overview of radiopaque bioceramics, specifically crystalline, non-crystalline (glassy), and nanostructured bioceramics designed for applications in orthopedics, dentistry, and cancer therapy. Furthermore, the modification of the chemical, physical, and biological properties of parent ceramics/biopolymers due to the addition of radiopacifiers is critically discussed. We also point out future research lacunas in this exciting field that bioceramists can explore further.
