Abstract
A total of 1370 children were examined for caries, gingivitis, periodontal pocketing, calculus and loss of marginal alveolar bone. The mean DFT and DFS scores were 6.2 and 8.7 for 11-yr-old children and 8.2 and 12.1 for 12-yr-olds. The average number of initial caries lesions was 12.4 among 11-yr-olds and 15.7 among 12-yr-olds. The proximal and smooth surfaces accounted for 37% of the total DFS score in the 11-yr-old children and 43% in the 12-yr-olds. The median DFS score for the 11-yr-old boys and girls was 7, while for the 12-yr-old boys it was 9 and for the girls 11. Only 1.8% of the children were free from caries. The occurrence of gingivitis, expressed by GBI, was 20 in both age groups. 8% of the children showed no advanced gingival inflammation, while less than 1% had bleeding gingivitis at all examined surfaces. Supragingival calculus was found in 10% of the children. Neither periodontal pocketing nor loss of marginal alveolar bone was observed.
