Abstract

Introduction: The jaw bones are susceptible to a variety of lesions. Understanding the prevalence and distribution of these lesions is crucial for informing preventative strategies within healthcare settings. This study aimed to evaluate the prevalence of intraosseous jaw lesions in a population referred to diagnostic and therapeutic centers in Zanjan, Iran, between 2013 and 2024.

Materials and Methods: This study employed a cross-sectional descriptive analytical design. This cross-sectional study, conducted in Zanjan in 2023, utilized structured data sheets to collect information on patients with intraosseous lesions. The collected data included demographic details (age, gender), lesion location, radiographic characteristics, and histopathological diagnosis. We applied Chi-square and Monte Carlo tests for statistical analysis.

Results: A total of 325 intraosseous lesions were reported in our study. A total of 214 intraosseous lesions were reported in this study. The most common group of lesions was inflammatory periapical lesions (49.5%), and the most common lesion was radicular cyst (26.6%). The mandible was the most common site of involvement (51.9%), and the most common clinical presentation was asymptomatic (83.2%). In both jaws, the most common group of lesions was inflammatory periapical lesions (61.2% in the maxilla and 38.7% in the mandible). No significant differences were observed in the distribution of lesion frequency based on gender or age group (p > 0.05).

Conclusion: This study contributes valuable data on the prevalence and distribution of intraosseous lesions within an Iranian population. These findings establish baseline information that can inform the development and implementation of preventative therapeutic protocols within healthcare facilities at the community level.
