Introduction: The present study aimed to assess the prevalence of periodontal bony lesions in radiographs in the Iranian population.
Materials and Methods:In this analytical cross-sectional study, 440 radiographic images of patients aged 15-60 years were selected based on the study’s inclusion criteria. Two researchers evaluated all radiographs and recorded patient age, gender, and bone-related lesions (horizontal , vertical and furca involvement) in a checklist. Chi-square test was used for data analysis. (α=0.05).
Results: 273 images (62.05%) had no lesions and 167 images (37.95%) had lesions. In the 167 examined images, a total of 845 bone lesions were observed . The highest frequency was in horizontal lesions in the anterior mandible and central incisor teeth and the lowest type of lesion was related to vertical lesions in the posterior mandible and in the third molar (P<0.001). The most types of bone lesions; Based on the type of tooth, was related to horizontal lesions in the lateral incisor and the lowest type of lesion was related to vertical lesions in the first premolar tooth (P<0.001). Based on restoration, the most related to horizontal lesions in amalgam and the least related to vertical lesions and furca in veneer (P<0.001). Based on the contact status, the most was related to horizontal lesions in open contact and the least was related to vertical lesions (P<0.001).
Conclusion:Based on this study, there is a significant association between the type of periodontal bony lesion and involved teeth, restoration type, contact status, presence of calculus on radiographs.
