Aim: The aim of this study was to compare the efficiency of conventional and digital radiography in assessing alveolar bone loss. Materials and Methods: The study group comprised 50 participants (25 males and 25 females) between 25 and 45 years of age. The participants were screened for all clinical features of periodontitis. A series of conventional bitewing radiographs of right and left of both maxillary and mandibular posterior region (15,16,17,25,26,27,35,36,37,45,46,47) were taken for each of 50 patients by examiner 1. Similarly, a series of digital bitewing radiographs were taken by examiner 2 for each 50 patients by using RVG of Planmeca Dixi 2 B Series. In digital bitewing radiographs, the measurement was done by examiner 2, using Planmeca Dixi 2 B Digital Software, by dragging the cursor to make a line by joining the linear points. Bone level less than 2 mm from the cementoenamel junction (CEJ) was considered normal while above that was considered bone loss. In case of conventional bitewing radiographs, alveolar bone loss was measured by the same examiner by measuring the distance from the CEJ to the most apical level of crestal bone using a divider and transparent ruler. The above collected data of examiners 1 and 2 were handed over to examiner 3 for statistical evaluation. Results: Comparison of conventional and digital radiographic techniques in left maxilla, left and right mandible, and between maxilla and mandible in the total sample and in females aged 25–35 and 36–45 years yielded a significant correlation while comparison of the two techniques in the right maxilla and between maxilla and mandible in males yielded a nonsignificant correlation. Conclusion: Direct digital radiography provides an edge over conventional radiography in assessing the periodontal bone destruction.
