目的 观察成年人与老年人龋病的自然发展过程以及与牙齿缺失的关系 ,为该病的防治提供依据。 方法 1 984年对 2 0岁以上成年人 587人的口腔状况进行了检查 ,1 994年随访复查4 40人 ,2次检查由相同的检查人员完成 ,对龋病的有关资料进行分析。 结果 各年龄组在 1 0年内均有新龋损形成 ,新增龋补牙数 ( DFT值 )随年龄增长而增加。 1 0年间所观察人群共丧失 2 1 1 4颗牙齿 ,占初查时存留牙齿总数的 1 8.9%。初查时无龋牙 1 0年后缺失 1 0 .8%,釉质龋牙缺失 1 7.9%,而牙本质深龋牙齿的缺失高达 76.0 %。 结论 龋病是影响成年人 ,特别是老年人健康的主要疾病 ,牙齿的缺失与初查时龋病的严重程度有关。如不积极改善口腔卫生和 (或 )进行干预 ,因龋病而丧失的牙齿数将随年龄增长而增加 ,从而影响生活质量
Objective To observe the natural progression of dental caries in adults and the elderly as well as its relationship with the loss of teeth so as to provide evidence for the prevention and treatment of the disease. Methods A total of 587 adults aged 20 years or older were examined for oral hygiene in 1984. Forty-four were followed-up in 1994, followed by two examinations by the same examiners. The dental caries data were analyzed. Results In all age groups, new carious lesions were formed in 10 years. The number of newly added dental caries (DFT value) increased with age. A total of 2,114 teeth were lost in the observed population during the first 10 years, accounting for 119.9% of the total number of teeth retained during the initial examination. Initial caries-free teeth had a loss of 1.08% after 10 years, a loss of 7.99% of enamel carious teeth, and a loss of as much as 76.0% of teeth with deep carious dentin. Conclusion Caries is a major disease that affects the health of adults, especially the elderly. The loss of teeth is related to the severity of caries during the initial examination. Without active improvement of oral health and / or intervention, the number of teeth lost due to dental caries will increase with age, thus affecting the quality of life
