title: Impact of audiovisual method in educating children facing dental avulsion.
abstract: BACKGROUND
  Dental trauma is a major problem in oral health in childhood especially if the result is a tooth avulsion. Subsequently, an appropriate management is essential to preserve the avulsed tooth.
  
  
  OBJECTIVE
  The goal of this study is to evaluate the knowledge of children concerning dental trauma and to highlight the importance of audio and visual methods in educating viewers in the management of such accident.
  
  
  METHODS
  Three hundred and forty four children, aged between 8 and 11 years old, participated in this study. Half of them answered a questionnaire about the management of a tooth avulsion. Then, they watch an educational movie played by a speaker. Three months later, they answer the same questionnaire. The remaining 172 children are divided into two equal groups A and B. Group A watches the movie, and group B listens to the story and answers the same questionnaire. One more time, both groups watch the film and listen to its verbal interpretation, then both answer the same questionnaire again. The answers are analyzed.
  
  
  RESULTS
  Before watching the movie, 4 of 172 children answer correctly the question related to the conservation of the avulsed tooth. Three months after watching the movie, the correct answers increase to 52. For the second part of the study, after audiovisual information, the full score in group A increases from 20 to 58, and in group B from 49 to 67.
  
  
  CONCLUSIONS
  The study highlights the importance of audiovisual method in transmitting an educational message and improving the knowledge of a large 'target audience'.
