The objective was to assess the relationship between number of functional occluding natural pairs of teeth and health related functioning in older free living Japanese people using the SF-20. The participants were 107 elderly people aged 80 years. Health related functioning was measured with the SF-20. The numbers of functional occluding natural pairs of teeth (OPs) were calculated and scored as follows: 1, for each pair of anterior teeth and premolars in occlusion. Molar functional natural occluding pairs were scored 2 for each occluding pair. The number of functional occluding pairs was assessed separately as anterior natural occluding pairs (AOPs) and posterior occluding pairs (POPs). There were significant differences in the role functioning subscale of SF-20 between those who were edentulous and those with one to nine natural teeth and 10 or more natural teeth (P = 0.030). Those with one to six AOPs had significantly higher role functioning than the zero AOPs group (P = 0.042). Those with 1-12 POPs also had significantly higher role functioning scores than the zero natural POPs group (P = 0.007). However, there were no significant relationships between number of natural teeth, OPs or AOPs, and POPs on the one hand, and all other subscales of SF-20 on the other hand. The community-dwelling 80-year-old Japanese people in this study had overall good health related functioning. The number of functional occluding pairs of natural teeth, especially POPs, was related with the role functioning subscale of SF-20 but had no significant relationships to the other dimensions of SF-20.
目的是使用SF-20评估日本自由生活的老年人中功能性咬合天然牙对数量与健康相关功能之间的关系。研究对象为107名80岁的老年人。使用SF-20测量健康相关功能。计算功能性咬合天然牙对（OPs）的数量并按以下方式评分：每对处于咬合状态的前牙和前磨牙计为1分。每对处于咬合状态的磨牙功能性天然牙对计为2分。功能性咬合对的数量分别作为前牙天然咬合对（AOPs）和后牙咬合对（POPs）进行评估。无牙者与有1至9颗天然牙者以及有10颗及以上天然牙者在SF-20的角色功能分量表上存在显著差异（P = 0.030）。有1至6对AOPs者的角色功能显著高于AOPs为零的组（P = 0.042）。有1至12对POPs者的角色功能得分也显著高于天然POPs为零的组（P = 0.007）。然而，一方面天然牙数量、OPs或AOPs以及POPs与另一方面SF-20的所有其他分量表之间均无显著关系。本研究中居住在社区的80岁日本老年人总体健康相关功能良好。功能性咬合天然牙对的数量，尤其是POPs，与SF-20的角色功能分量表相关，但与SF-20的其他维度无显著关系。
