Relevance. In childhood, traumatic tooth injuries are often found. Pulp necrosis occurs in 34,2 % of injured teeth, this causes damage to the periapical tissues. The post-traumatic complications (odontogenic cysts, periodontitis) in teeth with incomplete root formation often lead to a halt in root development. Chronic nidus of infection can be the cause of the somatic pathology development. This makes the early clinical and radiological diagnosis of post-traumatic complications important.
Objective of the work is to study the clinical features of the post-traumatic periodontitis of permanent teeth with incomplete root formation of the tooth and to assess the condition of periodontal tissues in permanent teeth with impaired root formation as a result of trauma based on data from clinical and radiological studies.
Materials and methods. On follow-up there were 17 children 9-15 years old with post-traumatic periodontitis of permanent teeth with incomplete formation of the root of the tooth. When making the diagnosis, we relied on data from clinical and radiological studies.
Results. Most children complained of an aesthetic defect. 9 children (52,9 %) after an acute tooth injury did not seek the help of a dentist, аfter treatment of 8 children, dynamic observation was not conducted. In 76 % (13 teeth) periodontitis is diagnosed in teeth with a crown fracture within the enamel, enamel and dentin.
It has been established that chronic granulating periodontitis is the most common form among destructive forms of periodontitis (12 teeth – 70,6%). Exacerbation of chronic granulating periodontitis diagnosed in 5 teeth. We did not ascertain chronic granulomatous periodontitis in teeth with incomplete root formation. The prevalence of the granulating form of chronic periodontitis in children is due to the histomorphological features of periodontal disease in childhood.
8 children, among the examined had a bite pathology – protrusion of the teeth of the front of the jaw (5 children) and a distal deep bite (3 children). In 71% of lesions, destructive forms of periodontitis were most often diagnosed in the maxillary incisors.
Conclusion. Untimely seeking help and the lack of dynamic monitoring of injured teeth are the main reasons for the development of post-traumatic periodontitis. The clinical course of periodontitis is peculiar – chronic granulating periodontitis predominates, the inflammatory process in periodontal tissues in childhood is characterized by rapidly progressive destruction of bone tissue. Malocclusion can be a risk factor for tooth injuries.
