Dental Erosion in Brazilian Children with Gastroesophageal Reflux Disease

ABSTRACT

To evaluate the occurrence of dental erosion (DE) in children with gastroesophageal reflux disease (GERD) and to analyse its association with diet, oral hygiene, socio-demographic characteristics and medical history.Material and Methods:The study sample consisted of43 children (2-14 years) with a positive diagnosis of GERD after 24-hour pH monitoring. Dental erosion was assessed by one trained examiner using the O'Sullivan index. A questionnaire was completed by parents, which provided information on dietary habits, oral hygiene, socio-demographics and medical history of the children. Data analysis was performed using a chi-square test and Poisson regression (p <0.05).Results:Dental erosion was diagnosed in 25.6% (N=11) of children. The most affected surfaces werethe palatal and incisal (62.1%, N=18). Socio-demographic characteristics and dietary habits were not associated with dental erosion occurrence. The regression model showed that children who used adult toothpaste (PR 4.98, 95% CI 1.34 -18.51) and asthma medication (PR 3.65, 95% CI 1.24 -10.70) had a higher risk of dental erosion.Conclusion:Dental erosion in children with GERD was associated with the use of adult toothpaste and asthma medication...
