Demographic and clinical information of each lesion &nbsp;was recorded. The results were analyzed using the chi-square statistical test in SPSS26 software<span dir="RTL" lang="FA">.</span><br> <b>Results:</b> Among 1054 jaw bone lesions&nbsp; 39 nonodontogenic lesions were found( 3.7%). Age of the subjects at the time of biopsy&nbsp; ranged from 8 to 59 years with a mean of 35.7 &plusmn; 12.3 .The most common non odontogenic lesion were tumors(38.5%) .Lesions were mostly seen in lower jaw(93.3%) , which was related to the type of disease(P = 0.04). Lesions most commonly occurred in females (61.5% ) although Chi square statistical test did not show this finding as significant (p=0.41) .One patient used long-term medication, and two had systemic diseases&nbsp; with no relation to the bone pathology diagnosed.<br> <b>Conclusion:</b> Non-odontogenic benign tumors were the most common type of non-odontogenic lesion in this study. Non-odontogenic lesions were mostly tumors seen in female patients and &nbsp;in mandible. For better understanding of these lesions future multicenter studies are recommended. &nbsp;</span></span></span><br> &nbsp;</div> 0 0 http://cofs.khuisf.ac.ir/browse.php?a_code=A-10-1-84&slc_lang=en&sid=1 Hamid Shajan 10031947532846001490 10031947532846001490 No Faculty of Dentistry, Isf.C., Islamic Azad University, Isfahan, Iran Atousa Aminzadeh 10031947532846001491 10031947532846001491 Yes Department of Oral and Maxillofacial Pathology Arezoo Tahmourespour 10031947532846001492 10031947532846001492 No Department of Basic Medical Sciences, Isf.C., Islamic Azad University, Isfahan, Iran Mehdi Abrishami 10031947532846001493 10031947532846001493 No Department of Oral and Maxillofacial Surgery, faculty of Dentistry, Isf.C., Islamic Azad University, Isfahan, Iran.
