Evaluation of diagnostic efficacy of bitewing with priapical radiography in complication of primary molar carries

Abstract

One goal of oral radiographs is to diagnosis of caries lesions and complications associated with it. The aim of this study was to evaluate the diagnostic value of bitewing and periapical radiography in detecting complication of caries in primary molars. It is hoped that the results of this study will be helpfull in selection a technique with minimal complications and maximum accuracy. Materials & Methods: From the primary molar teeth of the 120 children (3-6 years old), Bitewing and periapical radiography was obtained and in terms of relationship between dental caries and pulp, status of the primary teeth roots, periodontal ligament space in the furcation area, status of the underlying permanent tooth bud, were investigated. Data From the studies using software Spss21 and chi-square tests were analyzed. P values less than 0.05 was considered statistically significant. Results: The results showed that the accuracy of bitewing radiography in the detection of relationship beetwen caries and dental pulp was better (P<0.05). Accuracy of both techniques in the diagnosis of periodontal ligament space and Status of the primary teeth roots were the same (P>0.05). On the other hand, periapical radiography in the detection of the underlying permanent tooth bud Status was better (P<0.01). Conclusions: Accuracy of the bitewing radiography in the detection of relationship beetwen caries and dental pulp and Accuracy of the periapical radiography in the detection of the underlying permanent tooth bud Status was better. .
