Abstract
The most dramatic increase in dental decay is thought to have occurred during the last part of the 19th and the beginning of the 20th centuries. The aim of this study was to investigate the caries experience and pattern in primary and permanent teeth in a longitudinal study. Dental caries of 166 kindergarten children of 4-5 years old was recorded. Only 122 of the children were re-examined when their ages became 10-11. The third examination of 118 children was done when their ages became 13-14. Dental caries registration was done following the criteria of WHO (1987). Dental prevalence was increased by age reaching 94.9 percent at 13-14 years old. No sex differences were observed among the three examinations except in DMFT. The DMFT incidence after 6 years was 4.3 and after 3 years was 1.8, while DMFS incidence was 6.4 and 2.2 respectively. The D/d component was the highest mean value. Although dental caries was significantly higher in posterior than in anterior teeth, there were no jaw differences. Occlusal and proximal surfaces were the predominate surfaces affected among permanent and primary teeth respectively. Coinciding with the incline in caries experience observed among children, changes in the distribution and progression rate of the disease have been found.
