The actual problem of pediatric dentistry are the high prevalence of periodontitis of permanent teeth with immature root and difficulty in the treatment of such teeth. Odontogenic infections may be the cause of the development of general-somatic pathology. Endodontic use of drugs based on calcium hydroxide and MTA has disadvantages. The use of drugs based on hydroxyapatite is proposed, because of their properties – high biocompatibility and bioactivity. Objective: to define the efficiency of material based on hydroxyapatite in the treatment of periodontitis permanent teeth with immature root. Object and methods. At the dispensary supervision 49 children 9-15 years old (52 teeth) were. Temporary longterm obturation of root canals was performed using a paste based on hydroxyapatite – “OK 015” (first stage). The paste was prepared by kneading the metronidazole and granules “OK 015” to the cream-like consistency. Control of treatment was performed in a day, 2 weeks, 1, 3, 6, 9, 12 months. Permanent sealing of the root canal was performed after apexification (second stage of treatment). Results. Among surveyed, apical periodontitis most often appeared at the age of 10 and 11 years – 24,5% and 20,4% – respectively. In the early stages of the observation, in 7.7% of cases, a slight reaction from the tissues of periodontum was observed. After 3 months of treatment regeneration of the bone structure occurred in 11.53% of cases, apexification – 23.1%. Six months later, positive dynamics of bone regeneration was observed in 100% of children. X-ray reconstruction of bone tissue was confirmed in 41.3% of cases, apexification occurred in 60.9%. After 9 months, bone resection was observed in 73.4% of cases, apexification – in 84.6% of teeth. After 12 months, the recovery of bone tissue occurred in 81% of observations, in 96% – apexification. Thus, the most active processes of reparative osteogenesis and apexification took place at the time of 3-9 months. The faster rate of bone tissue regeneration and the formation of a mineralized barrier was revealed in cases of exacerbation of chronic apical periodontitis in the teeth of the upper jaw. The formation of a mineralized barrier is not always accompanied by a complete restoration of the structure of the periapical bone. Conclusion. The proposed method for the treatment of periodontitis of permanent teeth with immature root promotes reparative osteogenesis and apexification.
