This was to assess the prevalence of Early Childhood Caries (ECC) among preschool children attending nursery
schools and to compare the results with those of a previous survey where the investigators used the term and diagnosis for Baby Bottle
Tooth Decay (BBTD) syndrome.
A cross-sectional survey of 1,006 children aged 1-6 years was carried out. WHO
recommendations for oral health surveys were used for caries diagnosis (non cavitated lesions were excluded). In addition, a
comparison was made for prevalence of ECC between immigrant and native born children. Data were compared for ECC in the present
survey with BBTD data in a previous study (1994) in the same area with a sample of 401 children aged 4 years. All examinations were
by one examiner (Cohen's Kappa=0.96).
Of the 1,006 children originally selected 52 children aged more than 71 months
were excluded according to published ECC definition and diagnostic criteria. The overall sample was 29 children aged <36 months; 271 aged 3 years; 364 aged 4 years and 290 aged 5 years. ECC was diagnosed in 19.7 of the overall sample. The prevalence of ECC (and S-ECC) were respectively by age: <36 months S-ECC=17.2; at 3 years: 13.28 (6.64); at 4 years: 18.95 (9.34); at 5 years: 26.9 (12.75). In the native born children (916) the ECC was 18.34, while in immigrants (38) it was 52.63 (p<0.001). In 1994 the prevalence of BBTD syndrome was 11.9 and in the present study 6.5.
The ECC prevalence, as, ECC and severe (S-ECC) ,increased with age. In
immigrant children ECC was 3 times (S-ECC 6 times) more frequent than in native born. Using the BBTD diagnosis the prevalence had
dropped from 11.9 in 1994 to 6.5 in the present survey.
