Background/Aim:
Traumatic dental injuries are widespread and have become a serious dental public health problem in childhood. Despite its importance, very few studies have correlated the prevalence of permanent tooth injury and socioeconomic indicators. The aim of the present study was to evaluate just such a correlation.
Materials And Methods:
Electronic searches were performed in the following bibliographical databases: Brazilian Bibliography of Dentistry, Scientific Electronic Library Online, Latin American and Caribbean Health Sciences, The Cochrane Library, ISI Web of Knowledge, International Database for Medical Literature and PubMed Central. Reference lists from articles that fulfilled the inclusion criteria in this review were searched for additional relevant articles. The Brazilian Coordination of Higher Education Personnel Improvement Theses Databank was also included. Selection and analysis of the articles were performed independently by two authors of the present literature review.
Results:
A total of 21 of 98 articles were eligible for inclusion in the review. However, only nine articles performed all the methodology criteria analyzed. Seven of the surveys were carried out in Brazil and two in Thailand. The age of children was 9-14 years. Statistically significant associations between permanent tooth injuries and high economic status were found in four studies.
Conclusion:
There were few studies correlating traumatic injuries in permanent teeth and socioeconomic indicators and the majority found no such association. It is suggested that the association between traumatic dental injuries and socioeconomic factors may be related to the indicators used, considering differences in their individual components. Furthermore, the heterogeneity of the methodologies hinders the comparison of the studies.
