Análise radiográfica interproximal de perda óssea alveolar em crianças e adolescentes

Abstract

Periodontal diseases affect children, adolescents and young adults and may lead to considerable tissues damages, for example loosing teeth before 20 years old. However, to obtain disease diagnosis at early stages, bite-wings radiographs should be required in children and adolescents routine clinical examinations (GJERMO 1981). A random sample of 218 individuals, from Morvan (EM) public school and Bola Social Program (BF), from 6-15 years, was examined using posterior bite-wings radiographs and allocated according to age in subgroups from 6-9 years-old, (MB1), 10 to 12 years-old (MB2) and 13 to 15 years-old. After radiographic exams qualifications, 128 patient´s bite-wings exams were considered. CEJ -ACB (Cement enamel junction - alveolar cristal bone) distances, from second primary molars mesial surfaces to first molar distal surfaces and second pre molars mesial surfaces to first molar distal surfaces, were measured using a digimatic caliper. CEJ-ACB sites presenting > 2 mm would be considered bone loss. The overall alveolar bone loss prevalence was 1,56%, males and females were equally affected. Bite-wings exams were suitable for early bone loss detection and were good individual and group risk indicators for periodontitis diagnosis in children and adolescents.
