To investigate the relationship between functional tooth units (FTUs) and nutritional status.
One hundred females (mean age: 72.4 ± 8.2 years) at four private care homes in Jakarta, Indonesia were interviewed and clinically examined. The oral examination included the assessment of teeth, prosthetic status, and number of FTUs. The total number of FTUs was further divided by tooth composition: natural tooth against natural tooth (NN-FTUs), natural tooth against denture (ND-FTUs), and denture against denture (DD-FTUs). Nutritional status was evaluated using the body mass index (BMI) and the Mini Nutritional Assessment (MNA).
The mean numbers of teeth present, NN-FTUs, ND-FTUs, DD-FTUs, and total FTUs were 13.1 ± 10.4, 1.7 ± 3.0, 1.2 ± 3.3, 0.4 ± 1.2 and 3.3 ± 4.4, respectively. The mean BMI and MNA scores were 24.8 ± 5.0 and 22.6 ± 2.8, respectively. Subjects with a normal BMI had a significantly higher total number of FTUs (3.6 ± 4.6) compared with underweight subjects (0.1 ± 0.3). Subjects with a normal MNA had a significantly higher number of NN-FTU (2.6 ± 3.7) compared to those who were at risk or in a state of under-nutrition (1.2 ± 2.4).
This study revealed significant relationships between the number of FTUs and nutritional status. Keeping the posterior occlusion should be emphasized in order to maintain good nutritional status in older subjects.
探讨功能性牙单位（FTUs）与营养状况之间的关系。
对印度尼西亚雅加达四家私立养老院的100名女性（平均年龄：72.4±8.2岁）进行了访谈和临床检查。口腔检查包括牙齿、修复状况和FTUs数量的评估。FTUs总数进一步按牙齿组成分类：天然牙对天然牙（NN-FTUs）、天然牙对义齿（ND-FTUs）和义齿对义齿（DD-FTUs）。使用体重指数（BMI）和微型营养评定法（MNA）评估营养状况。
现存牙齿的平均数量、NN-FTUs、ND-FTUs、DD-FTUs和FTUs总数分别为13.1±10.4、1.7±3.0、1.2±3.3、0.4±1.2和3.3±4.4。BMI和MNA评分的平均值分别为24.8±5.0和22.6±2.8。BMI正常的受试者的FTUs总数（3.6±4.6）显著高于体重过轻的受试者（0.1±0.3）。MNA正常的受试者的NN-FTU数量（2.6±3.7）显著高于有营养风险或营养不足状态的受试者（1.2±2.4）。
本研究揭示了FTUs数量与营养状况之间的显著关系。为了维持老年受试者的良好营养状况，应强调保持后牙咬合。
