Background Dental erosion is a complication of gastroesophageal reflux Disease (GERD) in adults; in children, it is not clear if GER has a role in dental pathologic conditions. Dietary intake, oral hygiene, high bacterial capacity, and decreased salivary flow might contribute individually to GERD development or dental erosion, but their potential involvement in dental erosion from GER is not agreed. We investigated the prevalence of dental erosion among children with and without GER symptoms, and whether salivary flow rate to location-specific dental erosion.
Methods We performed a cross-sectional study of 40 children (ages,3–6 y) with symptoms of GERD and 30 asymptomatic children (controls); all completed a questionnaire on dietary exposure. Teeth were examined for erosion into dentin, erosion locations, and affected surfaces. All subjects responded a detailed frequency questionnaire related to acidic drinks, foods, and sugar consumption and participated in a clinical dental examination. The caries experience of the children was recorded according to World Health Organization criteria, and erosion was scored according to the Eccles and Jenkins grading scale.
Results This Survey showed that the prevalence of erosion on palatal surfaces of the primary teeth was 42% in 3–6-year-olds with GERD. This finding to be significantly higher than for healthy subjects (P<0.05). The salivary flow rate, and frequency of acidic drinks, foods, and sugar consumption were found to be similar in both groups.
Conclusion This current investigation has showed that GERD children were at an increased threat of developing erosion and caries compared with healthy subjects.
