Relevance. In children, post-traumatic complications in the teeth with incomplete formation of the root often lead to stopping the development of the root and premature loss of teeth. The instability of the results of endodontic treatment with calcium hydroxide preparations leads to the search for new treatments. Materials based on tricalcium phosphate ceramics attract attention because they contribute to the regeneration of bone tissue.

Objective: to evaluate the effectiveness of endodontic treatment of post-traumatic periodontitis of permanent teeth with incomplete root formation using bioceramics based on biological hydroxyapatite "Osteopatite ceramic" brand "OK 015".

Materials and methods. In children aged 9-15 years, 17 permanent teeth with post-traumatic complications were treated. In 12 cases, this was chronic granulating periodontitis. For a prolonged temporary obturation of root canals, a paste was used, which was prepared by mixing metronidazole and "OK 015" granules. The treatment was monitored every other day, 2 weeks, 1, 3, 6, 9, 12 months. Permanent root canal filling was performed after apexification.

Results. In the early stages of the observation of complications of treatment was not observed. 3 months after treatment, bone structure regeneration was activated, in 1 tooth – apexification. After 6 months, the positive dynamics of bone regeneration was observed in 100 % of children. X-ray reconstruction of bone tissue was confirmed in 35,3 % of cases, apexification occurred in 41,2 %. After 9 months, bone resection was observed in 59 % of cases, apexification – in 64 % of the teeth. After 12 months, bone tissue recovery occurred in 76,5 % of cases, in 94 % – apexification. Thus, the rate of apexification is ahead of the processes of reparative osteogenesis. The formation of a mineralized barrier is not always accompanied by a complete restoration of the structure of the periapical bone.

Conclusion. Material based on biological hydroxyapatite "Osteoapatite ceramic" brand "OK 015" for temporary obturation of the root canal promotes apexification and regeneration of bone tissue in the periapical region in the process of endodontic treatment of permanent teeth with unformed root in children.
