Analysis of oral health data from 13-15-year-olds from the ELSPAC study

Our study aim was to analyze the oral health state data obtained from 13-15 year old children from the ELSPAC group (European Longitudinal Study of Pregnancy and Childhood) monitored in Brno city. Material and Methods: Randomly selected children from the ELSPAC group (n=780) were examined clinically for dental and periodontal status, dental plaque, dental calculus and orthodontic anomalies. The following clinical parameters were assessed: DMFT score and its components, gingival index (GI), plaque index (PI) and calculus index (CSI). Gingivitis was measured using the modified Löe-Silness GI index. The presence of plaque and calculus was recorded according Silness-Löe (PI) and calculus surface index (CSI), respectively, without any disclosing agents. GI, PI and CSI were recorded on selected teeth. Presence/absence of orthodontic anomalies and its severity was recorded. To evaluate of the significance of differences between groups, F test for quantitative and 2 test for qualitative parameters were used. The study was approved by the ethical committee of Masaryk University. Results: Mean DMFT of the group was 2.82 (SE 0.36), share of caries-free children 25.4%. Mean GI index of the cohort was 0.204 (SE 0.011), grade 0 was found in 36.9% children, grade 1 in 43.0%, and grade 2 in 19.5%.
