Effectiveness of salivary stimulation using xylitol-malic acid tablets as coadjuvant treatment in patients with gastro-oesophageal reflux disease: Early findings

Description

Background: Besides dental erosion syndrome, other oral syndromes could benefit from the stimulation of sali vary secretion, in patients with gastro-oesophageal reflux disease (GORD). Our aims is evaluate the improvement of oral extra-oesophageal manifestations in patients with GORD using xylitol–malic acid tablets to stimulate salivary secretion. Material and Methods: The effectiveness of salivary stimulation using xylitol–malic acid tablets (as a supplement to omeprazole 40 mg/day) was assessed in a clinical trial (n = 14) lasting six months with patients with prior posi tive pH-metry, through GORD extra-oesophageal clinical signs, GerdQ and RDQ questionnaires, odontological variables, basal salivary secretion, stimulated salivary secretion, pH and buffer capacity, mucosal erythema index and dental wear. Statistics: chi-square (Haberman post-hoc), ANOVA, and Mann-Whitney U; variables between visits were evaluated with McNemar's Student's t and Wilcoxon tests; p < 0.05. Results: 100% of patients not taking xylitol–malic acid presented xerostomia, but only 14.3% of patients taking xylitol–malic acid (p < 0.01) did. The mean saliva-buffer capacity at the last visit for patients not taking xylitol– malic acid was 2.14 ± 0.38, versus 2.71 ± 0.49 for patients taking xylitol–malic acid (p < 0.05). Retro-sternal burn ing (p < 0.05), heartburn (p < 0.05) and regurgitation (p < 0.05) were also reduced. Conclusions: Xylitol–malic acid tablets improve quality of life among patients with GORD, by reducing dry mouth, increasing saliva buffering and reducing heartburn, retro-sternal burning and regurgitation.
