title: [Dental fillings in school-children from the Alcalá la Real-Martos Health District (Jaén)].
abstract: OBJECTIVE
  To evaluate 4-6 years later the state of dental fillings in 6-8 year old school-children treated at a health centre.
  
  
  METHODS
  Monitoring of a cohort with intervention.
  
  
  METHODS
  Alcalá la Real Health Centre (Jaén).
  
  
  METHODS
  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.
  
  
  METHODS
  Silver amalgam fillings in first permanent molars.
  
  
  RESULTS
  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.
  
  
  CONCLUSIONS
  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.
