Abstract
Asthma is a chronic disease that involves several healthcare services that need attention in relation to its treatment and prevention. The objective of this study was to evaluate caries, erosion, and enamel defects in children with and without asthma. Cross-sectional study, with a sample of 228 children ages 6-12years, stratified as asthmatic (n=112) and non-asthmatic (n=116), at two Primary Health Units of the Community Health Service, Brazil. The evaluation consisted of an oral examination and a structured interview with parents/guardians, in addition to data from medical records. Data were analysed by Poisson regression with a robust error variance, all of them at a level of significance of P<0.05. Of 112 asthmatic children, 63 (51.2%) had dental caries and 25 (53.2%) enamel defects. In the adjusted analysis, dental caries and use of salbutamol were associated (PR=1.32, 95% CI=1.01-1.72). In addition, children who performed oral hygiene more than three times a day showed a greater prevalence (PR=2.36, 95% CI=1.02-4.85) of dental erosion compared with children who performed it only once a day. There is no evidence for an association between asthma, caries, erosion, and enamel defect in children aged from 6 to 12years. There was, however, an association between dental caries and use of salbutamol.
