title: The role of saliva in regurgitation erosion.
abstract: It has been suggested that salivary characteristics are important in the progression of erosion. The aim of this investigation was to measure salivary parameters in 22 patients with erosion, 10 with normal (non-pathological) levels of reflux (Group I) and 12 with previously diagnosed pathological levels of gastro-oesophageal reflux (Group II). A further 10 subjects without evidence of erosion and no history of reflux disease acted as controls (Group III). No statistically significant differences in salivary flow rate, buffering power or the concentrations of calcium, phosphorus and fluoride were detected. The results suggest that variation in the characteristics of unstimulated and stimulated saliva collected during waking hours do not have a major role in erosion.
