Abstract

BackgroundThis 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.MethodsThe 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. The solubility was measured after one week by the ISO standard method. 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.ResultsThere were significant differences in the marginal adaptation, solubility and biocompatibility of the tested materials (P < 0.05). TheraCal LC showed the highest frequency distribution of gap presence that was followed by the MTA-Angelus then Biodentine. The least soluble material after one week was TheraCal LC that was followed by the MTA-Angelus and Biodentine. 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.ConclusionUnlike Biodentine, TheraCal LC is incapable of alternating the MTA in furcation perforation repair due to its poor biocompatibility and poor marginal adaptation.

Highlights

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
Marginal adaptation of the tested materials (Fig. 1) The highest frequency distribution of gap presence was recorded for the TheraCal LC that was followed by the Mineral trioxide aggregate (MTA)-Angelus
Solubility of the tested materials The highest mean solubility percent was recorded for the Biodentine (3.361178 ± 0.2621%, minimum value = 2.1% and maximum value = 4.3%), that was followed by the MTA-Angelus

Summary

Introduction

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. Several materials have been applied for repairing furcation perforation such as; reinforced zinc oxide eugenol, The 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 (3 h), Alazrag et al BMC Oral Health (2020) 20:298 difficult applicability and expensiveness [1,2,3]. The MTAAngelus (Angelus, Londrina, PR, Brazil) is another formulation of ProRoot MTA that has short sitting time (10 min) [4]. 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 [5]
