Impact of Untreated Traumatic Injuries to Anterior Teeth on the Oral Health Related Quality of Life As Assessed By Video Based Smiling Patterns in Children.

Introduction: The aim of the study was to assess the correlation between the oral health status, oral health related quality of life and the evaluations of their smiles as assessed by the children, their parents, and through measurements of the children's videotaped smiles and compare the smiling patterns in children suffering from untreated traumatic injuries to anterior teeth and control group.

Materials And Methods: Fifty eight children of the age 5-15 years of both sexes were selected for the study and categorized into experimental group and control group. The experimental group consisted of 29 children with untreated trauma to one or more anterior teeth while the control group consisted of 29 children with good oral health. Oral examination of all children was done to include in study groups. Children and parents participating in the study responded to two separate Oral Health Related Quality of Life questionnaires for children and parents respectively. The children were asked to watch a funny cartoon show and a video was made while the children watched the show. The video was cropped into still images at 25 predetermined points. Width and openness of the children's mouth and number of teeth shown were measured during the taped sessions to assess the children's video-based smiling patterns.

Results: The children's self evaluation scores had statistically significant correlation with their smiling patterns, the number of traumatized teeth and the parental assessment of their children's oral health. Children with trauma to anterior teeth had more impacts on their smiling pattern compared to control group.

Conclusion: Children suffering from trauma to anterior teeth had more effects on the emotions, the self confidence and social interaction than children without any traumatic injury.
