许多神经生物学、心理学和社会因素可能导致认知障碍。在动物研究中，牙齿状况和认知能力之间的关系已经被发现，但这种关系在人类中是否存在还不清楚。在第一步中，我们比较了1，351名天然牙齿参与者（53%女性，47%男性;年龄M = 54.0）与487名无牙参与者（59%女性，41%男性;年龄M = 71.3）在12项认知测试中的表现。天然牙组的平均年龄较低，女性较少，受教育年限较长，简易精神状态量表（MMSE）较高，在几项认知测试中表现明显较高。在随后的分析中，对一部分参与者（50-85岁）的认知表现进行了检查。在这项分析中，211人有自然牙列，188人无牙颌。这些组在性别、年龄、社会变量、疾病、压力和MMSE方面相匹配。无牙组的认知劣势仍然明显。结果表明，功能性天然牙与老年人相对保留的认知功能有关。
A number of neurobiological, psychological and social factors may account for cognitive impairment. In animal studies a relation between dental status and cognitive performance has been found. It is unclear whether such a relation exists for humans. In a first step we compared the performance of 1,351 participants (53% women, 47% men; age M = 54.0) with natural teeth to 487 edentulous participants (59% women, 41% men; age M = 71.3) on 12 cognitive tests. The natural teeth group had a lower mean age, fewer women, more years of education, higher mini-mental state (MMSE), and performed significantly higher on several cognitive tests. In a subsequent analysis, the cognitive performance of a subset of the participants (50-85 years) was examined. In this analysis, 211 had natural dentition and 188 were edentulous. The groups were matched for gender, age, social variables, diseases, stress and MMSE. The cognitive disadvantage of the edentulous group was still apparent. The results suggest that functional natural teeth relate to relatively preserved cognitive functioning in older age.
