Abstract
The aim of the study was to analyze the pathologic alterations of dental structures in 101 patients with esophagogastric passage insufficiency. Data were then compared to analogous ones obtained
in 78 control group subjects in whom no esophagogastric passage insufficiency was diagnosed. Patients with esophagogastric passage
insufficiency were found to have a significantly higher proportion of enamel erosion (27.7% or 6.7 erosions per subject) as compared to control group subjects with 18.9% or 3.6 affected teeth per subject, p< 0.01. Morphological characteristics of erosions were found to differ. In the study group, defects involving the entire tooth surface (generally palatinal, occasionally lingual) and tooth volume reduction were observed to predominate. In the control group, morphological alterations mostly included initial erosions with increased smoothness and loss of tooth surface gloss, and reniform or discoid defects of labial surfaces. Patients with esophagogastric passage insufficiency had a significantly reduced secretion of stimulated saliva (by 38.6% < 1 ml) as compared to the control group (5.1%, p< 0.01). Values of non-stimulated saliva p H were considerably lower in the study group patients (pH by 47.5% < 5) than in the control group subjects (p < 0.03). Statistically significant correlations between decreased amounts and lowered pH values o f stimulated saliva, as well as between p H o f non-stimulated saliva and increase in the prevalence of erosion in patients with esophagogastric passage insufficiency, were also observed.
