[Modern approach to the treatment of children with constant teeth avulsion]

Was to analyze treatment outcomes in children with constant teeth avulsion treated in Central Research Institute of Dentistry and Maxillofacial Surgery (CRIDMS).

The study comprised 39 children aged 7-16 years treated in CRIDMS in 2015-2020. In 38 cases from 39 replantation was performed more than 24 hours after trauma. Because of delayed replantation endodontic treatment was needed in 35 cases from 38 (in one case the avulsed tooth was missing). In all 38 cases replantation was followed by splinting with either resin splint made according to original technique proposed by the authors or semi-flexible splints from orthodontic wire fixed with resin composite.

In one case from 39 the avulsed tooth was missing because a dentist the child first consulted was unaware of the possibility of replantation. In 38 children followed-up for 6-57 months the replanted teeth survived and were clinically asymptomatic. There were, however, obvious radiological signs of replacement resorption in 27 (71.1%) cases. Inflammatory resorption was detected in two cases (5.2%) with immature teeth undergoing apexification with calcium hydroxide.

Replacement root resorption after tooth avulsion may be seen as relatively favorable outcome preserving more bone tissue than early tooth removal. The rate of replacement resorption, however, would be less in less delayed replantation. The study results proved the necessity for additional education of parents and pediatric dentists on the first aid and treatment tactics for teeth avulsion.
