[Prevalence of exogenous pigmentations and caries by intake of ferric supplements in primary dentition].

OBJECTIVE

The aim of this study was to determine the prevalence of extrinsic black pigmentation in primary dentition and its relationship with dental caries in children aged 3 to 5 years.

MATERIALS AND

METHODS

The study design was descriptive, prospective, cross-sectional and observational; The sample of the present study consisted of 79 children who were receiving treatment with ferrous sulfate, who underwent a clinical examination and odontogram. To determine the presence of extrinsic black pigmentation, the Shourie classification was used.

RESULTS

A low prevalence of extrinsic pigmentation of 7.6% was found, and children with extrinsic pigmentation had a Ceod of 9.83+-3.601, while those children without the presence of pigmentations had a Ceod of 4.60+-3.248.

CONCLUSIONS

A significant relationship was found between the Ceod index and extrinsic black pigmentation (p<0.001).
