Accuracy of Digital Panoramic Imaging in Detection of Proximal Caries in Posterior Teeth

Considering the irreversibility and rapid progression of dental caries, diagnosis and prevention of such cases is an important responsibility in the field of dentistry. Regarding the advantages of digital panoramic system and limitations of bite wing technique, this study aimed to compare the diagnostic accuracy of bite wing radiography and digital panoramic imaging in detection of proximal caries in posterior teeth.
This cross-sectional study was conducted on 30 patients who required both panoramic and bite wing radiographies for dental procedures. Radiographies were collected, coded, and evaluated by a radiologist. Then, the data were analyzed using the SPSS statistical software, version 18.0.
The results showed no significant difference between digital panoramic and bite wing techniques regarding accuracy in diagnosis of proximal caries in molar and premolar teeth. The sensitivity, specificity, and accuracy of digital panoramic radiography were 79.7%, 83.9%, and 82.8%, respectively, which revealed the high diagnostic precision of this technique in detection of proximal caries in posterior teeth.
Considering the insignificant difference between these two methods of radiography and the high sensitivity and specificity of digital panoramic radiography, this technique can be a proper substitute for bite wing radiography in diagnosis of inter-dental caries.
