Evaluating Significance of Patient’s Gender, Age, Systemic Diseases, Family History, and Smoking Status as a Predictor for Oral Aphthous Ulceration: An Analytical Cross-Sectional Study

Introduction: We aimed to investigate the significance of gender, age, systemic diseases, family history, and smoking status as predictor factors for recurrent oral aphthous ulceration. Methods: This cross-sectional study was conducted by paper and online questionnaires, which were distributed among the Iraqi population. The questions include the subject’s biographic data, history of recurrent oral ulceration, and characteristics. The data were collected and analyzed by binomial logistic regression. Results : The participants were 1101 (384 males and 717 females) with a mean age (24.3 ± 8.136). The prevalence of recurrent aphthous stomatitis was (73.8%) of the total subjects. The labial mucosa represents the most dominant site. Symptoms duration lasted for 1 week in most questioned subjects. Age, systemic disease, and family history were significant predictors. Gender and smoking were not significant predictors. Conclusions : Age, history of systemic disease, and family history of ulceration were effective predictors for recurrent aphthous ulceration.
