Abstract

OBJECTIVE

Many people have dental arches with unrestored edentulous areas posterior to natural teeth. One dental pattern is the shortened dental arch (SDA). As a result of the lack of teeth, individuals with an SDA may eat a restricted diet, including soft, highly processed foods. Such diets may increase the risk of being overweight or of obesity. We examined whether there was an association between SDA and body mass index (BMI) in adults 45-65 years of age.

METHODS

The data for this study were US National Health and Nutrition Examination Survey (NHANES) 2005-2008 merged files. There were 5,773 eligible participants. The data were examined for frequencies, and the results were analysed using the chi-square test and logistic regression.

RESULTS

There were 69.3% participants with a shortened mandibular arch and a BMI of ≥25 compared with 71.8% of participants who had a complete mandibular dental arch and a BMI of ≥25 (P=0.7246). There were 70.6% of participants with a shortened maxillary arch and a BMI of ≥25 compared with 71.9% of participants who had a complete maxillary dental arch and a BMI of ≥25 (P=0.8859). The adjusted odds ratio for shortened mandibular dental arch was 0.70 (95% CI: 0.46-1.08) for a BMI of ≥25 as compared with individuals with a BMI<25. The adjusted odds ratio for shortened maxillary dental arch was 1.06 (95% CI: 0.63-1.78) as compared with individuals with a BMI<25.

CONCLUSIONS

The research hypothesis that an SDA was related to higher BMI, and the corollary that restored or complete dentition had better odds of a lower BMI, were not supported.

摘要

目的

许多人的牙弓在天然牙后方存在未修复的无牙区。一种牙型是短牙弓（SDA）。由于牙齿缺失，患有SDA的个体可能饮食受限，包括食用柔软、高度加工的食物。这类饮食可能会增加超重或肥胖的风险。我们研究了45至65岁成年人中SDA与体重指数（BMI）之间是否存在关联。

方法

本研究的数据来自2005 - 2008年美国国家健康与营养检查调查（NHANES）的合并文件。有5773名符合条件的参与者。对数据进行频率检查，并使用卡方检验和逻辑回归分析结果。

结果

下颌牙弓缩短且BMI≥25的参与者占69.3%，而下颌牙弓完整且BMI≥25的参与者占71.8%（P = 0.7246）。上颌牙弓缩短且BMI≥25的参与者占70.6%，而上颌牙弓完整且BMI≥25的参与者占71.9%（P = 0.8859）。与BMI<25的个体相比，下颌牙弓缩短且BMI≥25的调整后优势比为0.70（95%置信区间：0.46 - 1.08）。与BMI<25的个体相比，上颌牙弓缩短的调整后优势比为1.06（95%置信区间：0.63 - 1.78）。
