ABSTRACTThe objective of the study was to evaluate the benefit left from free dental care at public school after an average time interval of 7 years (mean: 7.03 years). The school dental service given to 66 Army recruits was extracted from their respective school dental care records, and then compared with the caries situation at the time of their military service. The results showed that the average number of 10.42 filled and extracted tooth surfaces at the end of school dental care had increased to a score of 36.72 DMFS 7 years later. The increase was significantly higher than expected on the basis of the average caries development between ages 7 and 15 years. Of the teeth filled during school dental care, only 26% were in no need of additional treatment, 15% had been properly retreated afterwards and the rest were either decayed (35%), retreated and redecayed (13%) or extracted (11%). Of the teeth that had been given root canal treatment at school, 27% had been extracted within the following 7 years. The caries situation was worst in the group of recruits who had had free dental care for the longest period of time. It was concluded that constant free repair of the teeth does not seem to give long term relief from the caries problem.
