Endodontic treatment of complicated traumatic deciduous teeth damage--a case report.

The 11-year-old boy was diagnosed with severe external root resorption of the tooth 11 and chronic exacerbated apical periodontitis of the tooth 12. Additionally, the tooth 12 showed signs of dilaceration. The history revealed that at the age of 5, the boy had dislocated his maxillary deciduous incisors with impaction to the tissues. The root canal treatment of the teeth 11 and 12 was performed with the application ofBiopulp, Jodoform, and Metronidazole paste to the canal. The dressings were changed every 4 weeks for 6 months. The root canals of both teeth were filled with the Resilon Epiphany System. The root apex of the tooth 11 was additionally sealed with Pro Root MTA preparation. Defects in crowns were closed with composite material. On followup examination (6 and 12 months after the beginning of the treatment), the patient did not complain of any pain. The radiological picture showed complete healing of periapical structures of the tooth 12 and lack of resorption progress in the tooth 11.
