Prevalence and Clinical Features of Biopsied Jaw Lesions in an Iranian Population Patient in 7 Years

Jawbones can be affected by many lesions such as genetic, metabolic, inflammatory, cysts, and tumors. For proper diagnosis and treatment, t is necessary for dentists to be aware of the most prevalent lesions, demographic and clinical features, and their distribution patterns in every population. The present study aimed to evaluate the distribution pattern of jaw bone lesions in 7 years in Isfahan, Iran.

This retrospective analytic descriptive study was performed on 370 reports available from the department of oral pathology at Isfahan Azad university. demographic data, clinical features, and histopathology diagnosis were gathered and analyzed statistically by ANOVA and Chi-square (α = 0.05).

Intraosseous lesions consisted 28.6% of all lesions.41.5% in females and 58.4% in males (p < 0.05. (Mean age of male patients was 35.96 and 33.70 for females (p value > 0.05). Lesions were mostly in the right lower jaw (p value < 0.05). The swelling was the only clinical feature reported in only 15% of 106 intraosseous lesions, 73 cases were odontogenic cysts,19 inflammatory,9 odontogenic tumors,2 benign non-odontogenic tumors, and 3 non-odontogenic cysts. The periapical and dentigerous cyst was the most prevalent lesions reported.

Results of the present study showed jaw bone lesions mostly occurred in the right lower jaw in male patients. it is understood that the distribution of intraosseous lesions of the oral cavity is related to genetic, environmental, and geographic factors. Further studies are required.
