Three freshly human extracted single rooted teeth were obtained from patients who received orthodontic treatment at the outpatient clinic, Faculty of Dentistry, Ain Shams University, Egypt. Therefore, this study compared the repair potential of TheraCal LC Resin Modified Calcium Silicate material against the MTA-Angelus and Biodentine as a furcation perforation repair material, in terms of marginal adaptation, solubility and biocompatibility. The hypothesis of this study was that TheraCal LC will alternate the MTA and Biodentine as a furcation perforation repair material. The marginal adaptation, solubility and biocompatibility are the main tested properties of the furcation perforation repair materials. Therefore, evaluation of the physical and biological properties of this newly introduced resin modified calcium silicate-based material (TheraCal LC) is thought to be valuable. Due to its high physical properties and low solubility, TheraCal is applied mainly as a barrier and for protection of dental pulp complex. TheraCal LC (Bisco Inc, Schaumburg, IL, USA) is a new light-curing Resin Modified Calcium Silicates (RMCS) material that has been recorded to enhance apatite formation and secondary dentin. In recent years, innovations are still carried out to introduce recent endodontic repair materials that overcome the shortcomings of the available materials. A modified powder constituents, addition of setting accelerators and softeners, and a new predosed capsule formulation are responsible for the improvement of the physical properties of biodentine. Д«iodentine (Septodont, Saint-Maurdes-Fosses, France) is an alternative to MTA due to its similar properties when compared with the MTA, but with better handling properties and faster setting time. TheВ MTA-Angelus (Angelus, Londrina, PR, Brazil) is another formulation of ProRoot MTA that has short sitting time (10В min). TheВ MTA is one of the most commonly used root repair materials due to its good biocompatibility, marginal adaptation, bacterial leakage, and low cytotoxicity, but it has some drawbacks such as long setting time (3В h), difficult applicability and expensiveness. An ideal perforation repair material should be inducing osteogenesis, cementogenesis and good sealing, nontoxic, noncarcinogenic, biocompatible, dimensionally stable and insoluble in the body's fluids. Several materials have been applied for repairing furcation perforation such as reinforced zinc oxide eugenol, amalgam, super EBA, calcium hydroxide, composite resins, glass ionomer, MTA, bioaggregate, biodentine, platelet rich plasma (PRP), platelet rich fibrin (PRF) and others, but none of them has the characteristics of an ideal repair material. Furcation perforation of the pulpal floor in multi-rooted teeth results in periodontitis and irreversible attachment loss. Perforations represent pathologic or iatrogenic connections between the root canal space and the external tooth surface. Unlike Biodentine, TheraCal LC is incapable of alternating the MTA in furcation perforation repair due to its poor biocompatibility and poor marginal adaptation. After one month and three months, TheraCal LC showed the highest inflammatory response and highest frequency distribution of radiolucency that was followed by the Biodentine then MTA-Angelus. The least soluble material after one week was TheraCal LC that was followed by the MTA-Angelus and Biodentine. TheraCal LC showed the highest frequency distribution of gap presence that was followed by the MTA-Angelus then Biodentine. There were significant differences in the marginal adaptation, solubility and biocompatibility of the tested materials ( PвЂ‰<вЂ‰0.05). Biocompatibility was evaluated by the inflammatory response and radiography after one month and three months of repair of experimental furcation perforations in dog's teeth.

The solubility was measured after one week by the ISO standard method. The marginal adaptation was assessed by scanning electronic microscope and presence of any gap between the dentin surface and filling material in each quadrant of the sample was analyzed at 1000 X magnification. This study evaluated the marginal adaptation, solubility and biocompatibility of TheraCal LC compared with mineral trioxide aggregate (MTA-Angelus) and Biodentine when used as a furcation perforation repair material.
