Abstract
Background: Considering the relatively high prevalence of systemic diseases, the present study investigated the frequency of systemic diseases in patients referring to the surgery department of the Zahedan Faculty of Dentistry. Methods: In this descriptive-analytical cross-sectional study, 463 patients referring to the surgery department of the Zahedan Faculty of Dentistry in 2021 - 2022 were investigated. The required information, including the type of systemic disease, age, gender, and marital status, was extracted from the patient's medical file and recorded in the designed checklist. Next, the frequency of systemic disease was compared in terms of age, gender, and marital status. Results: The frequency of systemic diseases was obtained at 27.4%. The most common systemic diseases were hypertension (8.6%), diabetes (6.6%), and anemia (4%). The frequency of systemic diseases in terms of gender and marital status did not differ significantly (P = 0.567 and P = 0.193, respectively), while it was significantly higher in those above 45 years of age compared to those younger than 45 (P < 0.001). Conclusions: The prevalence of systemic diseases in patients referring to the surgery department of the Zahedan Faculty of Dentistry is relatively low compared to other studies. Hypertension, diabetes, and anemia had the highest frequency among systemic diseases.
