A Retrospective Study of Oral and Maxillofacial Pathology Lesions Diagnosed at the Faculty of Dentistry, King Abdulaziz University

Background: Oral and maxillofacial lesions (OMFL) comprise a broad spectrum of benign and malignant lesions that affect the oral cavity. However, few epidemiological studies have evaluated oral cavity lesions, and very few have focused on oral soft tissue pathology. The purpose of this study was to identify the prevalence and distribution of OMFL that had been diagnosed histologically at the Oral Pathology Laboratory, Faculty of Dentistry, King Abdulaziz University.

Materials And Methods: A retrospective study was conducted to assess the distribution of OMFL among the oral cavity biopsies submitted to the Oral Pathology Laboratory during the period from 1996 to 2016. Information on sex, age, location of the lesion, and histopathologic diagnosis was analyzed.

Results: A total of 1,218 cases were examined. Among these, reactive/adaptive lesions were the most common type (n=245; 20.1%) and cystic lesions were the second most common (n=214; 17.6%), followed by inflammatory lesions (n=152; 12.5%) and epithelial pathology (n=115; 9.4%).

Conclusion: The results of the present study provide valuable information on the prevalence of OMFL in Jeddah, Saudi Arabia. Reactive conditions were the most frequently diagnosed pathologies. Most oral and maxillofacial biopsies were soft tissue lesions, benign in nature, and inflammatory in origin. Further studies are necessary to provide more information on head and neck diseases in the general population to develop better future oral health policies.
