Abstract
Saliva is known to be protective for esophageal mucosa. Increased chewing strokes result in a quantitative and qualitative enhancement of saliva. Reduction in the amount of saliva produced results in an increased incidence of gastroesophageal reflux disease (GERD), which can be objectively measured by the DeMeester score. The impact of increased chewing strokes on the DeMeester score remains largely unknown, thus this study aimed to find out their impact on the value of the DeMeester score and its individual components.The effect of increased chewing strokes on the DeMeester score was investigated in 12 subjects (5 male and 7 female) who were diagnosed with GERD. All subjects underwent a 48-hour pH monitoring using the Bravo® pH capsule. All the patients chewed their food 20 times more on Day 2 as compared to Day 1. The data were analyzed for change in the DeMeester score and its individual components in 2 days.In patients with GERD (DeMeester score > 14.72 on Day 1), the number of long refluxes (>5 minutes) on Day 2 (mean = 3.2, SD = 2.3) was significantly lower than on Day 1 (mean = 6.4, SD = 2.7); Z = -2.032, p = 0.04. Though, the DeMeester score and its other individual parameters decreased on Day 2, they were not statistically significant.In patients with GERD, increased chewing strokes lead to a decrease in the number of long reflux episodes. Though there is a decrease in the DeMeester score and its other individual components, larger randomized controlled studies are required to reach statistical significance.
