To determine if moderate to severe dementia has an effect on the oral health of individuals resident in nursing homes.
A significant proportion of the elderly population lives in nursing homes and suffers from varying degrees of dementia. Dementia might affect an individual's ability to implement oral care. Previous work in this area has focused on individuals with mild dementia living in the community setting.
Two matched cohorts of subjects resident in four nursing homes in Cheshire were recruited (n=135). One cohort's subjects were deemed to have no or mild dementia, whereas the other cohort's subjects were deemed to have moderate to severe dementia. Oral parameters were scored, including Decayed, Missing, Filled Teeth (DMFT) scoring, dental deposit scoring, denture assessment and the noting of any other pathology.
There was a statistically significant difference in the relative level of dementia of the subjects between the two cohorts (p<0.01, Student's t-test). The DMFT scores were similar for both groups. The mean number (+/-SD) of decayed and missing teeth for the no/mild dementia group was 1.11 (+/-3.42) and 28.22 (+/-6.64), whilst that of the moderate/severe dementia cohort was 0.80 (+/-1.87) and 27.28 (+/-7.73), respectively. Eleven per cent of the moderate/severe dementia cohort wore an upper denture alone as compared with 16% in the no/mild dementia group.
For individuals resident in nursing homes, moderate to severe dementia might have a deleterious effect on oral health. Further work in this area is required.
确定中重度痴呆是否会对养老院居民的口腔健康产生影响。
相当一部分老年人口居住在养老院，患有不同程度的痴呆症。痴呆可能会影响个人实施口腔护理的能力。该领域以前的研究主要集中在社区环境中患有轻度痴呆的个体。
招募了柴郡四家养老院中两组匹配的受试者队列（n = 135）。一组受试者被认为没有或患有轻度痴呆，而另一组受试者被认为患有中重度痴呆。对口腔参数进行评分，包括龋失补牙数（DMFT）评分、牙菌斑评分、义齿评估以及记录任何其他病变情况。
两组受试者的痴呆相对程度存在统计学显著差异（p < 0.01，Student's t检验）。两组的DMFT评分相似。无/轻度痴呆组龋坏和缺失牙齿的平均数量（±标准差）分别为1.11（±3.42）和28.22（±6.64），而中重度痴呆队列分别为0.80（±1.87）和27.28（±7.73）。中重度痴呆队列中有11%的人仅佩戴上半口义齿，而无/轻度痴呆组为16%。
对于居住在养老院的个体，中重度痴呆可能会对口腔健康产生有害影响。该领域需要进一步开展研究。
