Parent and caretaker knowledge about avulsion of permanent teeth.

Traumatic dentoalveolar injuries are frequent in children and adolescents, affecting teeth, their supporting structures and adjacent soft tissues and contributing to the appearance of major psychosocial and economic problems. Tooth avulsion, the most severe dentoalveolar lesion, is a dental emergency. The prognosis of avulsed teeth significantly depends on prompt and efficient action at the site of the accident, thus requiring that parents or caretakers be knowledgeable about the correct management of this situation. The objective of the present study was to assess the level of knowledge of parents or caretakers concerning the management of tooth avulsion and to investigate the association between level of knowledge and schooling, monthly family income and age. We interviewed 107 parents or caretakers using a 12-item questionnaire comprising objective questions whose answers received a score from 0 to 3. The results show that 99% of those interviewed would immediately seek professional help; however, 71% did not know what avulsion was. Only 3% would use milk as storage medium and 16% would attempt replantation of the avulsed tooth. The distribution of final means for the overall level of parent or caretaker knowledge was 44.63% for score 3, 15.88% for score 2, 17.99% for score 1 and 21.47% for score 0, showing a low level of knowledge concerning tooth avulsion. Schooling, monthly family income and age were not associated with the knowledge scores for any of the 12 questions. The level of parent and caretaker knowledge concerning the management of tooth avulsion is low, without association with age, schooling and monthly family income.
