Background and ObjectiveRadiographic examination has an important role in diagnosis and treatment of periodontal patients, so this study was performed to determine the accuracy of digital bite wing (CMOS) radiography in alveolar bone resorption.

Materials and Methods: This cross-sectional study was performed on 61 teeth of 16 periodontal patients referred to the periodontoloy department of Rafsanjan Faculty of Dentistry. The patients were selected using available sampling. The patients were examined by a periodontist and the distance of Cemento Enamel Junction (CEJ) to the alveolar crest, after injection if needed, was measured by William’s periodontal probe with accuracy of 1 mm, in mesial and distal surfaces of the premolars and first molars. Then digital bite wing radiography was taken from the patients and the mentioned distance was determined by CMOS linear software analysis program by an oral radiologist. Data were analyzed using paired t- test and simple linear regression.

  • The results showed that the mean of alveolar bone resorption (mm) in CMOS radiography is significantly less than clinical examination (p<0.001). By simple linear regression model, the mean of alveolar bone resorption (mm) in clinical examination, is predictable from the amount of alveolar bone resorption on CMOS radiography with accuracy of more than 99%.
  • Digital bite wing radiography (CMOS) measures the mean of interproximal alveolar bone resorption in posterior teeth less than clinical examination, but regarding the high accuracy of CMOS radiography measures (more than 99%) in predicting probe depth, it might be possible to apply this radiography in detecting the interdental alveolar bone loss of posterior teeth.
