A CPITN survey was conducted on 1958 institutionalised elderly people aged 59 years and older at 29 of the 30 public and private institutions in the city of Kitakyushu, Japan. About 60 per cent of the sample was edentulous, and the prevalence of periodontal conditions was high. The percentages of dentate subjects with healthy gingivae, bleeding on probing, calculus, shallow pockets, and deep pockets were 3, 4, 32, 52, and 9 per cent respectively. Half the sextants in the dentate subjects were scored as excluded (less than two teeth), indicating that many teeth were missing. Only very few sextants were healthy. These findings indicate the importance of preventive programmes for periodontal diseases in the younger generations, because (a) dental care for the elderly population becomes more difficult with increasing age and (b) periodontal care, if it is available at all, is provided too late for most people.
在日本北九州市30家公立和私立机构中的29家，对1958名年龄在59岁及以上的机构养老老年人进行了社区牙周治疗需要指数（CPITN）调查。样本中约60%无牙，牙周疾病患病率很高。有牙受试者中牙龈健康、探诊出血、有牙石、浅袋和深袋的百分比分别为3%、4%、32%、52%和9%。有牙受试者中一半的牙区段被评为排除（少于两颗牙），表明许多牙齿缺失。只有极少数牙区段是健康的。这些发现表明了针对年轻一代开展牙周疾病预防项目的重要性，原因如下：（a）随着年龄增长，老年人口的牙齿护理变得更加困难；（b）即使能提供牙周护理，对大多数人来说也为时已晚。
