项目摘要

To clarify the relationship between oral conditions and aspiration pneumonia, we examined oral and systemic conditions of 307 subjects of the elderly (males, 80 ; females, 227 ; average age 81 ± 11 ; edentulous subjects, 110 ; dentulous subjects, 197) hospitalized in Haradoi Hospital in Fukuoka from February to April, 1999. Ninety percent of subjects were partially or completely abed. Completely bedridden subjects showed higher rate of use of denture, and had higher number of C4 teeth, more maxillary dental calculus and more deposits on the palate. However, the relationship between the bedridden condition and the tooth number or periodontitis was not found. We examined the frequency and duration of a fever (more than 37.5ィイD1゜ィエD1C) till December, 1999. Sixty-two percent of subjects fevered. Weak relationship between the frequency and duration of a fever and the tooth number, the number of occlusion sites, the amount of deposits on the palate or the amount of expectoration. In 156 dentulous subjects, weak negative relationship between the frequency and duration of a fever and plaque index (PI) at mandibular anterior teeth was found. However, any relationship between those of a fever and denture plaque or periodontal pocket was not found. Weak relationship between the average attachment loss and the duration of a fever was found. When we performed the logistic regression analysis with a fever as an independent variable adjusted with age and ADL. The adjusted odds ratio of a fever in subjects with more than 15 teeth was 2.3 (P = 0.011). When added PI as a varialble in only dentulous subjects, the odds ratio was 2.83 (P = 0.012). Higher PI showed lower odds ratio of a fever. In both dentulous and edentulous subjects, the odds ratio of denture-using persons showed higher than that of denture-unusing ones.

为了明确口腔状况与吸入性肺炎的关系，我们于1999年2 - 4月对福冈原都医院住院的307例老年人（男80例，女227例，平均年龄81±11岁，无牙110例，无牙197例）进行口腔及全身状况检查。90%的受试者部分或完全卧床。完全卧床者义齿使用率高，C4牙数量多，上颌牙石多，上颚沉积物多。然而，卧床与牙齿数量或牙周炎之间的关系尚未发现。我们检查了发烧的频率和持续时间（超过37.5 D1C），直到1999年12月。62%的受试者发烧。发烧的频率和持续时间与牙齿数量、咬合部位数量、上颚沉积物数量或咳痰量之间的关系很弱。在156名有义齿的受试者中，发现发热频率和持续时间与下颌前牙菌斑指数呈弱负相关。而发烧与假牙菌斑或牙周袋之间没有任何关系。平均依恋损失与发烧持续时间之间存在弱关系。当我们将发烧作为随年龄和ADL调整的自变量进行逻辑回归分析时。15颗牙以上发热的校正优势比为2.3 （P = 0.011）。当仅在有牙的受试者中添加PI作为变量时，优势比为2.83 （P = 0.012）。PI越高，发烧的比值比越低。在有义齿和无义齿的受试者中，使用义齿者的优势比均高于未使用义齿者。
