Evaluation of an interdisciplinary preventive programme for early childhood caries: findings of a regional German birth cohort study.

OBJECTIVES

The aim of this prospective birth cohort study was to evaluate the effect of the interdisciplinary preventive programme (PP) for early childhood caries in 3-year-old children in Germany.

MATERIAL AND

METHODS

From July 2009 to October 2010, all parents of newborns (n = 1162) were visited after birth by the communal newborn visiting service of Jena, Thuringia, and advised on general and dental health. In the first year of life, children were invited to a dental examination in Jena University Hospital. Participating children were included in a risk-related recall system with continuous oral care over 3 years. Caries-risk assessment tool of the AAPD was used for risk categorizing. High-risk children received fluoride varnish biannual. In 2013, the total birth cohort (participants and non-participants) was invited to evaluate the PP. Dental caries was scored using WHO diagnostic criteria expanded to d1-level without radiography. Data were analysed statistically (multivariate logistic regression).

RESULTS

Seven hundred fifty-five children (mean age 3.26 ± 0.51 years) were examined. Children in the PP (n = 377) showed significantly lower caries prevalence and experience than non-participants (15.6 vs. 37.8 %, 0.9 ± 3.3 d1-4mfs vs. 2.6 ± 5.2 d1-4mfs). Lack of vitamin D supplements (OR = 1.9, CI 0.99-3.51), familial caries experience (OR = 2.2, CI 1.27-3.73) and visible plaque on teeth (OR = 6.5, CI 4.41-9.43) were significant risk factors for caries development, whereas regular dental care (OR = 0.5, CI 0.38-0.79) had a protective effect.

CONCLUSIONS

The PP was an effective interdisciplinary approach for preventing early childhood caries in small children.

CLINICAL RELEVANCE: Early dental visits with caries-risk-related preventive dental care are necessary to prevent early childhood caries (ECC).
