Prevalence of Semi-Erupted First Permanent Molar Occlusal Caries and Evaluation of Related Clinical Factors in Children

Abstract

Background : Occlusal caries in semi-erupted first permanent molars may be the result of special anatomy, long eruption period and incomplete enamel calcification. The aim of this study was to evaluate the relationship between occlusal caries of those teeth and dmft, oral hygiene and plaque on the occlusal surface.Materials and Methods : Total of 193 semi-erupted first permanent molars were evaluated in 85 Zahedanian children concerning the occlusal caries, the amount of plaque on this surface, molar dmft, oral hygiene, dental arch, side and sex.Results : The occlusal surface of 21.8% of the samples was decayed and there was only a significant correlation between the amount of plaque on the occlusal surface and also dmft with occlusal carries (p=0.03).Conclusion : Too much plaque on the occlusal surface and dmft are related with occlusal carries.
