The relationship between body mass index (BMI) and dental caries is still undetermined.
This study aimed to assess the relationship between the dental status by decayed, missed, filled teeth index (DMFT), and BMI by age and gender among healthy adults.
Analytical, cross-sectional study.
University dental hospital in Riyadh.
Healthy adults aged between 18 and 35 years were recruited during the 10-month period from March 2015 to December 2015. Dental caries severity was estimated using the DMFT index.
The prevalence of overweight/obesity and the association of BMI category with the DMFT index.
The mean age of 502 subjects was 24.3 (4.9) years. The caries severity of the study population was considered moderate according to the WHO caries severity scale (mean [standard deviation] DMFT 13.3 [3.8]). The mean (SD) DMFT of male and female subjects was 13.1 (4.0) and 13.36 (3.7), respectively. No significant association was seen between dental caries and BMI. Logistic regression analysis showed that males had two times more risk of developing dental caries compared to females. In addition, the risk of caries development was increased by about 5 times for every year of age.
Dental caries was not associated with BMI but age significantly influenced the DMFT index and gender was associated with more missing teeth. Further longitudinal studies with larger cohorts from several geographic regions are warranted.
Convenience sampling and recruitment from a single dental center may have some impact on the generalization of data.
体重指数（BMI）与龋齿之间的关系仍未确定。
本研究旨在评估健康成年人中按龋失补牙指数（DMFT）衡量的牙齿状况与按年龄和性别划分的BMI之间的关系。
分析性横断面研究。
利雅得的大学牙科医院。
在2015年3月至2015年12月的10个月期间招募了年龄在18至35岁之间的健康成年人。使用DMFT指数评估龋齿严重程度。
超重/肥胖的患病率以及BMI类别与DMFT指数的关联。
502名受试者的平均年龄为24.3（4.9）岁。根据世界卫生组织的龋齿严重程度量表，研究人群的龋齿严重程度被认为是中度（平均[标准差] DMFT为13.3 [3.8]）。男性和女性受试者的平均（标准差）DMFT分别为13.1（4.0）和13.36（3.7）。龋齿与BMI之间未发现显著关联。逻辑回归分析显示，男性患龋齿的风险是女性的两倍。此外，年龄每增加一岁，患龋齿的风险增加约5倍。
龋齿与BMI无关，但年龄对DMFT指数有显著影响，性别与更多牙齿缺失有关。有必要从几个地理区域进行更大样本量的进一步纵向研究。
便利抽样和从单一牙科中心招募可能会对数据的推广产生一定影响。
