Abstract

Session 1 – Oral Epidemiology – Congress Hall Friday 8 September 2006. Chairs: Professor Eino Honkala and Professor Neda Markovska Trends in oral health and treatment need among children and adolescents. Z BROUKAL1*, R IVANCAKOVA2, E LENCOVA1, L MRKLAS1. 1Institute of Dental Research, 1st Faculty of Medicine, 2Faculty of Medicine, Hradec Kralove, Charles University in Prague, Czech Republic Surveys of oral health status and treatment need of selected age categories of Czech children and adolescents have been conducted approximately every three years since 1994 with the latest survey in 2004. Aim To ascertain the trends in oral health and treatment need by comparing caries experience, dental status and treatment need from four consecutive surveys in the past ten years. Methods In each survey, dental practitioners in randomly selected areas have examined approximately 20,000 individuals aged 5, 12, 15 and 18 years. The data were entered into standard WHO dental records. The areas included in the surveys have been the same throughout the ten-year-period. For each survey, the mean values have been calculated for the following parameters of oral health and treatment need: % caries-free (5-year-olds), dmft/DMFT, dt/DT (5, 12, 15 and 18-year-olds), and % in need of restorative care (dt/DT>0) (5, 12, 15 and 18year-olds). For assessing possible trends, regression lines were plotted for the individual parameter values stemming from the four consecutive surveys. Student’s t-tests were used for evaluating the statistical significance of the regression coefficients with the threshold for significance set at p<0.05. Results 5-year-olds: Percentage of cariesfree 23.9, 24.7, 29.8 and 41.6 (ns) for 1994, 1997, 2000 and 2004, respectively. Mean DMFT: 12-year-olds 3.1, 3.2, 3.1 and 3.0 (ns), 15-year olds 5.8, 5.6, 5.4 and 5.2 (p<0.05), 18-year-olds 8.4, 7.8, 7.4 and 7.0 (p<0.05). Mean dt/DT: 5-year-olds 2.2, 2.2, 1.9 and 1.5 (p<0.05), 12-year-olds 0.8, 0.8, 0.9 and 0.8 (ns), 15-year-olds 1.2, 1.1, 1.2 and 1.3 (ns), 18-year-olds 2.1, 1.8, 1.5 and 1.3 (p<0.05). Percentage in need of restorative care: 5-yearolds 63.9, 61.1, 53.5 and 46.0 (p<0.05); 12-year-olds 43.4, 39.8, 33.9 and 28.5 (p<0.05); 15-year-olds 53.2, 52.2, 51.6 and 50.4 (ns); 18-year-olds - 68.5, 63.3, 59.3 and 57.7 (p<0.05). Conclusions Between 1994 and 2004: caries experience declined in 15- and 18-year-olds but not in 5- and 12-year-olds; mean dt/DT decreased in 5- and 18-year-olds but not in 12- and 15-year-olds; percentage of subjects in need of restorative treatment declined in 5-, 12- and 18-year-olds but not in 15-year-olds. Irrespective of some partial improvement it can be stated that the current preventive and restorative care are not effective enough to cope with the caries situation among the Czech children and adolescents.

Z VESELINYOVÁ*, N MARKOVSKÁ I. stomatologická klinika UPJŠ a FNLP, Košice, Slovak Republic Poor oral health is widely recognized as a problem that cannot be solved by means of dental care only. Family members and school teachers are also important. Slovakia is one of the countries that were not able to fulfil the WHO goals by the year 2000. WHO is collecting dental data from nearly 200 countries, mostly DMFT index values for 12-year-old children but in recent years increasingly also data on caries situation among the 5-year-olds. In Slovakia and Eastern European countries, preventive programmes are not fully established for the latter age group. Aim To determine the level of oral health among a group of 5-year-olds living in Slovak Republic. Methods In the years 2004-2005, we examined 137 children, 82 boys and 55 girls of whom 76 lived in the town of Košice and 61 in the neighbouring villages. In a clinical oral examination, dental caries and the level of oral hygiene were recorded. The parents of the children also answered a questionnaire that included questions about oral hygiene habits and the use of oral health services. Results Only 29% of the children were caries-free. The mean dmft score was 5.5 with untreated dentinal caries being the predominant component of the index score. The most affected teeth were molars. In a similar study in 1987, the mean dmft score had been 3.4. Visible dental plaque was found in 30% of the children. There were no statistically significant differences between boys and girls or between children from the town and villages. The analysis of the questionnaire revealed that 35% of the children had not yet visited a dental office. It was also found that among the parents only 50% had visited the dental office regularly for prevention and only one third reported using dental floss or a mouthwash. Conclusions The study confirmed the necessity of revitalizing the systematic dental care for preschool children and establishing functional health promotion programmes in schools in order to advise the children and their parents to adopt appropriate oral health habits.
