Abstract

 Background and Aim: Early diagnosis of dental problems can prevent so many complications. Treatment of Priority Index (TPI) was introduced by Grainger (1967) for screening and assessing the severity of MALOCCLUSION and defines priorities for treatment. The purpose of this study was to evaluate the TPI in the school children (3rd-5th grade) of West Azerbaijan Province in 2005-2006.Materials & Methods: This study was done cross-sectionally with a random cluster sampling method. 550 schoolchildren with mixed dentition were selected. All examinations were done by a trained practitioner, using periodontal probe, tongue blades on a chair in the room light. The TPI of each child was assessed and registered in the questionnaire. The data was analyzed with t-test and ANOVA statistical methods.Results: The average TPI was 2.78±2.65 ranging from 0.27 to 18.17. In 160 cases (29.1%) TPI was in normal range.Whereas 268 persons (48.7%) showed minor manifestations of MALOCCLUSION, 83 cases (15.1%) had definite need to treatment. Severe problem was seen in only 29 persons (5.3%) and 10 persons (1.8%) had suffered from very severe problem. No statistically significant difference was found between the mean TPI values of male and female subjects.Conclusion: According to TPI, it seems that half of the population needed slight orthodontic treatment but one-fifth required variety of mandatory orthodontic therapies. This group requires special attention and application of preventive measures.
