AN INNOVATIVE APPROACH TO THE TREATMENT OF TRANSVERSE FRACTURES OF MOLAR ROOTS

A tooth fracture is a traumatic injury to a tooth with the disturbance of its crown or root part integrity. A root fracture is a fracture that involves cementum, dentin, periodontium and, in some cases, dental pulp. Root fractures occur in 0.2-7% of all cases of permanent teeth injuries. The aim of the study was to investigate clinical effectiveness of using a material based on hydroxyapatite «Bioplast-Dent» paste and a material based on mineral trioxide aggregate - «Rutsil» in the treatment of a transverse fracture of the medial tooth root 4.6 (clinical case). The object of the study was a patient with a fracture of the medial tooth root 4.6 and destructive processes in the tissues of the apical periodontium of tooth 4.6, who applied to the Chair of Restorative Dentistry with the course of the Faculty for Advanced Training & Retraining of «VSMU» in 2019. Temporary obturation of the root canals of the root of tooth 4.6 was performed using the material based on hydroxyapatite «Bioplast-Dent» in the form of a paste. Permanent obturation of the root canals of the root of tooth 4.6 was carried out using domestic material based on mineral trioxide aggregate (MTA) - «Rutsil». The final restoration of the tooth crown was carried out after X-ray control from the moment of permanent obturation of the root canals in 3 months. Additionally, dynamic R-control was performed in 12 months. The results of the treatment have shown that the use of hydroxyapatite-containing paste and domestic material based on mineral trioxide aggregate - «Rutsil» brings about activation of osteogenesis in periodontal tissues and stops the process of resorption in the fracture line, shortening the time of bone tissue recovery and contributing to a greater success of treatment.
