Prevalence of carious lesions in early and late mixed dentition orthdontic patients

ABSTRACT

To investigate the commonly affected carious teeth in the early and late mixed dentition period of male and female orthodontic patients. A total of 224 [Male Female ratio 118 106] patients were diagnosed in the early mixed and late mixed dentition in 3 age subgroups; 6-7 years, 8-10 years and 11-13 years at the patients were investigated regarding carious lesions in the maxillary and mandibular dentition, carious lesions in male and female subjects, carious lesions in primary and permanent teeth. Intra-oral examination and radiographs [orthopantogram and peri-apical] were done for each patient to confirm the carious lesions. The mandibular dentition was affected 3 times more than the maxillary dentition [mean values for total mandibular dentition 62.3 and total mean value for maxillary dentition 28.6]. Males [total mean value 75.7] were affected 3 times greater as compared to the female patients [total mean value 21.9]. 8-10 years age group has the highest carious prevalence [total mean value 54.6] followed by the 11-13 years age group [total mean value 24.6] and the 6-7 years age group [total mean value 18-7]. Both primary and permanent mandibular molars had more carious lesions as compared with the maxillary molars. Mandibular 2nd primary and 1st primary molars and permanent lower 1st permanent molars had the highest carious lesions. 8-9 years age group had the highest carious lesions for both primary and permanent teeth. Males had more [ratio 31] carious lesions as compared to the females
