To evaluate 4-6 years later the state of dental fillings in 6-8 year old school-children treated at a health centre.
Monitoring of a cohort with intervention.
Alcalá la Real Health Centre (Jaén).
In the school years 94-95 and 95-96 a total de 88 second-year EPO (compulsory primary education) students received at least one occlusal silver amalgam filling in their first permanent molars. 4-6 years later, 78 students, who had had 157 fillings, were examined.
Silver amalgam fillings in first permanent molars.
The success or failure of the fillings was measured. The failure rate was 11.5% (95% CI, 6.0-17.0), with authentic failures (marginal infiltration, recurrent caries, broken filling and broken tooth) (58.8%) predominating over false failures (caries elsewhere) (41.2%). Neither sex, age when the filling was inserted, dental arch (upper or lower), nor the index of temporary caries at the start were statistically linked to the failure of fillings.
In clinical terms, the health centre has an adequate level of efficacy 4-6 years after inserting simple silver amalgam fillings in 6-8 year old school-children.
评估在健康中心接受治疗的6 - 8岁学童4至6年后牙齿充填物的状况。
对一个队列进行干预监测。
阿尔卡拉拉雷亚尔健康中心（哈恩省）。
在94 - 95学年和95 - 96学年，共有88名小学二年级（义务教育阶段）学生在其第一恒磨牙上接受了至少一次咬合面银汞合金充填。4至6年后，对78名曾有157颗充填牙的学生进行了检查。
第一恒磨牙的银汞合金充填。
测量充填物的成功或失败情况。失败率为11.5%（95%可信区间，6.0 - 17.0），真实失败情况（边缘性渗漏、继发龋、充填物折断和牙齿折断）（58.8%）多于假失败情况（其他部位龋坏）（41.2%）。性别、充填时的年龄、牙弓（上颌或下颌）以及开始时的乳牙龋指数均与充填物失败无统计学关联。
从临床角度来看，在6 - 8岁学童中植入简单银汞合金充填物4至6年后，该健康中心具有足够的疗效水平。
