Introduction: Alveolar bone level is changed due to the balance between bone formation and resorption. Precise examination of alveolar bone is done by clinical and radiographic methods. Radiographic examination has an important role in diagnosis and treatment of periodontal patients, so this study was performed to determine the accuracy of bitewing radiography in alveolar bone resorption. Materials & Methods: This analytical and cross-sectional study was performed in 37 interdental osseous wall of patients who referred to the periodontology department of Babol dental faculty for periodontal surgery in 2004. Vertical bitewing radiography was done in premolar and molar region by use of Snap-A-Ray film holder. A caliper with accuracy of 0.05 mm was used for measuring the level of interdental bone resorption on cliche. During periodontal surgery the amount of bone resorption was measured by Williams probe. Then datas were analyzed by paired-t-test and Pearson correlation coefficient and linear regression. Results: The mean value of alveolar bone resorption with Williams probe and bitewing radiography was 2.66±1.2 and 2.81±1.06 in maxillary molars, 2.31±0.75 and 2.5±1.6 in mandibular molars, 1.73±1.03 and 1.93±0.97 in maxillary premolar and 1.91±1.11 and 2.25±1.59 in mandibular premolars respectively. Conclusion: According to the results, bite wing radiography had high accuracy in measuring the amount of alveolar bone resorption. So, this method can help to diagnose and determine treatment plan of periodontal disease. Key words: Bite wing radiography, williams probe, alveolar bone resorption.
