Frequency and severity of dental caries in foster care children of Turin, Italy: a retrospective cohort study

Authors:

ABSTRACT

Aim

Aim of this retrospective cohort study was to assess the frequency and severity of dental caries (DC) among foster care
children in the city of Turin, in North West Italy, and to compare these data with those of a general paediatric population. MATERIALS
AND

Methods

From May 2016 to September 2018, 75 paediatric subjects between the age of 4 and 12, located in 11 residential
child care communities were recruited. Instructions were provided concerning oral health, caries and correlation with dietary habits. Oral
and dental examination were carried out to establish frequency and severity of caries (not-penetrating, nPC, corresponding to the
International Caries Detection and Assessment System (ICDAS) codes: 1–4, vs. penetrating, PC, corresponding to ICDAS codes: 5-6).
Decayed, missed, filled teeth (DMFT) index was used. Data for comparison were acquired from the WHO Collaboration Center For
Epidemiology and Community Dentistry of Milan (WHO-CCOMS), belonging to a nationwide sample of 2,141 Italian children.

Results

Only 13 subjects (17%) were caries-free; 187 caries were identified: 133 were PC, whereas 54 were nPC. Overall, 76% of
the caries were found in deciduous teeth. Mean DMFT was 3.43 (D = 2.97; M = 0.24; F = 0.22). When the study data were compared to
those from WHO-CCOMS, a significantly higher DMFT (3.43 vs 0.96; p <0.00001) and D (2.97 vs 0.62; p <0.00001) was detected.

Conclusion

A significant higher frequency of caries in foster care children in Turin, Italy compared to the general population was
detected.
