    Abstract:
    PURPOSES: The purposes of this study were to determine the prevalence of caries in a sample of Brazilian schoolchildren, test associotions between caries, sociodemographics, and erosion, and investigate potential dietary factors common to both conditions. METHODS: Brazilian schoolchildren (13-14 years old) completed a questionnaire to provide dietary information and underwent dental examination. Sociodemographic characteristics were collected using a questionnaire completed by parents/guardians. Caries was assessed using decayed, missing, filled teeth/ surfaces (DMFT/DMFS) indices. Erosion was assessed using a previously validated index. RESULTS: Of 458 schoolchildren, 78% had caries experience. A statistically significantly lower prevalence of caries was observed in children from a higher economic class and whose parents had higher educational levels. Thirty-five percent of children with caries also had erosion, while 32% with a DMFT of 0 had erosion (P = .72). The frequency of consumption of drinks and foods was not statistically significantly associated with caries. The intake of sugared carbonated drinks was statistically significantly associated with erosion (P = .01). The mothers' educational level was the only variable independently associated with caries experience (P = .04). CONCLUSIONS: Dental caries was associated with sociodemographics, but not with erosion. There were no dietary factors identified in common for caries and erosion.
