P01 - Changing prevalence of Early Childhood Caries in Czech 5-year- olds (1998-2008) BROUKAL Z1*, LENCOVA E, SKIBOVA J2 1st Faculty of Medicine1, Charles University in Prague Institute of Clinical and Experimental Medicine2, Prague, Czech Republic Aims: To compare the prevalence of the early childhood caries (ECC) in the population of 5 year-olds in two nation-wide surveys conducted in 1998 and 2008. Methods: Dental examinations were conducted according to the WHO caries assessment criteria (1997). After ethical committee approval and informed parental consent d3mft, d3t, sic and ri (means and SD) were calculated. The caries involvement (d, m, f) of upper deciduous incisors higher than that of upper deciduous molars in children with all upper deciduous teeth present was taken as the putative epidemiological criterion for ECC (Lencova et al. 2002). The data were statistically tested using Student t test and χ2 tests. Statistical significance was set at the p<0.05 level. Results: Altogether 435 children were examined in 1998 and following basic characteristics were found: caries free 26.7%, d3mft 3.68; SD 2.33, d3t 2.51, sic 7.71 and ri 25.3%. The survey in 2008 (n=905) revealed 37.4% of caries free, mean d3mft 1.96; SD 1.88, mean d3t 0.66, sic 5.62 and ri 33.8% - a statistically significant improvement in all calculated parameters of dental status. In 1998, 94 of children examined (21.6%) came under suggested criteria for ECC, 4.1% with one incisor involved, 8.3% with two incisors, 4.4% with three incisors and 4.8% with all upper incisors involved (mean d3mft 5.17; SD 3.87). The respective data in 2008: 18.0% (n=163) of ECC children, 2.2% with one, 4.4% with two, 2,7% with three and 8.7% with all upper incisors decayed (mean d3mft 4.39; SD 3.34). Conclusions: The significant decrease of the prevalence of ECC was found between 1998 and 2008 with the nonsignificant change of the d3mft means in ECC cohorts of 5-yr old children. In both surveys (1998, 2008), 48.5% of children meeting the above ECC criteria have fallen into the SIC (one third with highest caries experience) cohorts.

P02 - Severe early childhood caries in children attending a private dental clinic in Bucharest MUNTEANU A*, LUCA R, VINEREANU A Carol Davila University, Bucharest,, Romania Due to its relatively high frequency, as well as its local and general consequences, severe early childhood caries (S-ECC) still represents a public health issue. Aim: To evaluate the prevalence and severity of S-ECC in a group of children seeking various dental treatments in a private dental clinic in Bucharest (Romania). Methods: A retrospective study using dental records of children examined and treated in a private dental clinic between 2003 and 2007 was performed. Children aged 71 months or younger were selected. The study group consisted of 233 children (124 boys) aged 36 to 71 months (mean age 48.84±16.79 months). One child was edentulous. The prevalence index for S-ECC (IpS-ECC) and carious experience indexes (dmft/dmfs and SiC) were calculated for the whole group and separately for boys and girls. The location and severity of carious lesions were recorded. Data were analyzed using chi square test. Results: Sixty eight children (29.2%) were caries free. The prevalence of ECC was 38.19% (40.32% for boys and 35.21 for girls). Mean dmft=8.54±3.82 (boys: 8.44±3.73; girls: 8.67±3.98) (dt=8.20±3.85). Mean dmfs=18.43±11.96 (boys: 19.06±13.35; girls: 17.62±10.01) (ds=17.34±12.09), SiC=13.00. Seventy two percent of the S-ECC children that sought treatment were older than three years showing little parental concern on the matter during early stages of caries. Seventeen of the 89 S-ECC children (19.10%) had caries even on their lower incisors. Sixty four of the S-ECC children (71.92%) already had pulp involvement, which was the reason for seeking treatment. Conclusions: S-ECC prevalence index was high, with high caries experience indexes, mainly given by the “d” component. Preventive programs are still needed in order to improve parents’ knowledge of proper care for primary teeth, to raise awareness regarding the need for early treatment of this caries and to encourage the first dental visit before occurrence of pain.
