Abstract
In Central and Eastern Europe oral health systems are in transition due to the economic and political changes. The aim of the present study was to highlight the long-term trend in dental caries prevalence of Hungarian children. A WHO National Pathfinder Survey of oral health status was conducted in 1996 which included 6-year-olds (n = 900) and 12-year-olds (n = 900). Similar surveys were performed in 1985 (age 6-7, n = 895; age 12, n = 893) and in 1991 (age 5-6, n = 898; age 12, n = 898) and the surveys were based on the same sites and examination criteria. Clinical data were collected by trained dental examiners according to the WHO Basic Methods. In 1996, 73% of 5-6-year-olds and 84.5% of 12-year-olds were affected by dental caries. At age 5-6 the mean dmft was 4.5 and at age 12 the DMFT was 3.8. In both groups, the d/D-components were high (5-6 years: dt/dmft = 89%; 12 years: DT/DMFT = 45%). For children aged 5-6, the mean caries experience increased from 1991 (3.7 dmft) to 1996 (4.5 dmft) (P<0.01) whereas DMFT of 12-year-olds declined from 5.0 in 1985 and 4.3 in 1991 (P<0.01). The differences in caries experience by urbanization level were reduced over time. In 1996, 72% of 12-year-olds had gingival bleeding (CPI scores 1+2), and 23% had moderate/severe malocclusion. In conclusion, in order to meet the need for dental care in schoolchildren in Hungary health authorities are encouraged to revitalize the school dental services. Implementation of community-based health promotion is needed to control oral disease in Hungarian children.
