The clinical manifestations of the gastroesophageal reflux disease (GERD) are multiple and heterogeneous, differing according to age and individual susceptibility. The relationship between respiratory manifestations and the gastroesophageal reflux (GER) in children is a controversial topic on: proving or refuting either cause or effect, with special stress on the most important symptom – cough. Dental erosions can be GERD-related, especially in the case of infants or of neurologically-impaired children. The case of a 4 year and 8 month-old child with gastroesophageal reflux, with typical (chronic vomiting) and atypical (chronic cough, dental erosions) digestive manifestations, a diagnosis established by pH-metry associated with multichannel intraluminal impedance, will be discussed in the study.
