The relationship between body mass index (BMI) and oral disorders remains unclear. This study examined the prevalence and types of dental abnormalities and oral mucosal lesions among female students with obesity attending a Taif University sports centre.
This non-interventional cross-sectional study enrolled female students with high BMI from a university sports facility using a convivence sampling method. The participants were divided into three BMI groups. Data were collected using an interview and by clinical oral examination. Prevalence and oral disorder types and possible mechanisms linking BMI and dental development were evaluated.
Ultimately, 86 female students with obesity were analysed. The mean BMI was 42.8 kg/m2, indicating high obesity levels. A weak although statistically significant correlation was observed between age and BMI (r=0.27), indicating that older students had higher BMI. A statistically significant association was observed between BMI and dental abnormalities (p0.05). The dental abnormality prevalence increased with BMI, ranging from 37.5% to 40.7% in the ≤40 and >45 kg/m2 groups, respectively. Most participants (66.3%) had oral mucosal lesions, with the highest prevalence among participants in the 40-45 kg/m2 group (71.4%).
A statistically significant relationship was observed between BMI and dental abnormalities; obesity may negatively affect oral health.
体重指数（BMI）与口腔疾病之间的关系尚不清楚。本研究调查了在塔伊夫大学体育中心就诊的肥胖女性学生中牙齿异常和口腔黏膜病变的发生率和类型。
本非干预性横断面研究采用便利抽样法，从一所大学的体育设施中招募了高 BMI 的女性学生。参与者被分为三组 BMI 组。使用访谈和临床口腔检查收集数据。评估了 BMI 与牙齿发育之间的相关性以及口腔疾病的发生率和类型。
最终分析了 86 名肥胖女性学生的数据。平均 BMI 为 42.8kg/m2，表明肥胖程度较高。年龄和 BMI 之间存在微弱但具有统计学意义的相关性（r=0.27），表明年龄较大的学生 BMI 更高。BMI 与牙齿异常之间存在统计学显著相关性（p<0.05）。牙齿异常的发生率随 BMI 增加而增加，在≤40kg/m2 和>45kg/m2 组中分别为 37.5%和 40.7%。大多数参与者（66.3%）有口腔黏膜病变，在 40-45kg/m2 组中患病率最高（71.4%）。
BMI 与牙齿异常之间存在统计学显著关系；肥胖可能会对口腔健康产生负面影响。
