Caries prevalence and tooth loss in Hungarian adult population: results of a national survey.

Background: Oral health is basically important for the well-being of people. Thus, it is strongly suggested to organize epidemiological surveys in order to gain representative data on oral condition of the given population. The purpose of the cross-sectional study was to determine the results on tooth loss and caries prevalence of Hungarian adults in different age groups.

Methods: Altogether 4606 persons (2923 women, 1683 men) participated in the study who were classified into different age groups: 19 [less than or equal to], 20-24, 35-44, 45-64, 65-74, [greater than or equal to]75 year olds. Probands were selected randomly from the population attending the compulsory lung screening examinations. The participants were examined by calibrated dentists, according to the WHO (1997) criteria. In order to produce representative data, the chosen localities for these examinations covered the capital, the largest towns, the villages, and case weights were used for the statistical evaluation.

Results: The mean values of DMF-T were found between 11.79+/-5.68 and 21.90+/-7.61 These values were significantly higher in women compared to men (p < 0.05). In all age groups the values of M were the highest. Except for the women in the groups of 35-44 and 45-64 year olds, these values showed an increasing tendency both in women and men by age (from 5.50+/-6.49, and 4.70+/-4.08 to 21.52+/-9.07 and 18.41+/-8.89 respectively). The values of D components reached the highest values in 45-64 year olds (4.54+/-2.12 and 4.22+/-2.81, by gender, respectively), then in the older age groups there was a high reduction in these values (in 65-74 year olds: 2.72+/-1.88 and 1.36+/-2.48; in 75 or more than 75 year olds: 1.05+/-1.41 and 1.03+/-1.76 by gender, respectively). The ratio of D and F values was the highest in the age group of 65-74 year olds (2.12), the lowest ratio could be calculated in 20-34 year olds (0.65).Data showed some decrease in caries experience in 35-44 years of age between 2000 and 2004. The prevalence of persons with 21 or more teeth had been increased from 65.6% to 73.1%. This positive tendency has not been occured in prevalence of edentulousness in this age group: the prevalence of edentulous persons changed from 1.4 to 1.9%. In 65-74 year olds the level of edentulousness became lower, from 25.9 to 14.8% and the prevalence of persons with 21 or more teeth is higher (22.6%) than it was in 2000 (13.0%).

Conclusion: Present data from Hungary show some slight decrease in caries experience between 35-44 years of age, although this positive tendency has not been occured in prevalence of edentulousness in this age group. A positive tendency could be experienced in the group of 65-74 year olds in edentulousness and in number of teeth, but further efforts are needed to reach a better situation.
