Overview

Introduction, Aim:
Avulsion of permanent teeth is one of the most serious dental injuries, and a prompt and correct emergency management is very important for the prognosis of replantation. The aim of this study was to find out the causes that lead to dental avulsion, and to analyze the factors that influenced the success of replantation.

Methods:
In our study we analyzed the documentation of a sample of 46 patients who had a total of 49 avulsed teeth (17 teeth with open apices, 32 teeth with closed apices) and were treated in Dentistry Department of Medical Faculty in Pilsen. We looked for the causes of the dental injuries, healing after replantation and occurrance of complication. Teeth with closed and open root apices were compared using the Fisher´s exact test.

Results:
In our study the most common causes of the avulsion of the permanent teeth were cycling and sport or game injuries. Early replantation (within 30 minutes after injury) was performed only in five cases. Only 14 teeth were transported to the replantation in moist transport medium. Prophylactic endodontic treatment showed necrotic pulp in all 32 teeth with closed apices. Based on the x-ray examination superficial resorption was observed in 15 replanted teeth (31%), replacement resorption was found out in 21 teeth (43%). External inflammatory resorption afflicted 13 teeth (26%), more frequently teeth with open apices (p = 0,0383). Extraction of tooth was more often performed in teeth with open apices (p = 0,0127).

Conclusions:
The study showed better prognosis of the replantation of permanent teeth with closed apices.

Keywords:
avulsion – replantation – external resorption
