Association of erosion with timing of detection and selected risk factors in primary dentition: a longitudinal study.
OBJECTIVE
The aims of this study were to determine the prevalence of erosion in a birth cohort at 24, 36, and 48 months and to investigate risk factors for erosion.


METHODS
One hundred and fifty-four children from a birth cohort were followed at 24, 36, and 48 months of age.


RESULTS
Of the 154 children examined, 0% (0/154), 7% (11/154), and 28% (40/154) had erosion detected for the first time at 24, 36, and 48 months, respectively (P < 0.001). A cumulative total of 51 (33%) children and 256 (8%) teeth had erosion by the age of 48 months. There were no significant associations between erosive lesions first detected at 36 months and oral hygiene behaviour, medical conditions, or dietary habits reported at the 24- or 36-month examinations (all P > 0.05). In contrast, erosive lesion first detected at 48 months was positively associated with the use of a feeding bottle reported at the 36-month examination (P = 0.026).


CONCLUSIONS
The prevalence of dental erosion in young children increased with age, with clinically detectable lesions forming between 24 and 36 months of age. Erosive lesions first detected at 48 months were positively associated with the use of a feeding bottle reported at 36 months.
