Health authority | Switzerland: Ethikkommission |
Study type | Interventional |
Dental erosions in 30 male and female patients with proven abnormal gastrooesophageal reflux
will be assessed clinically and using a novel optical coherence tomography (OCT) laser
technique before and after double-blind randomization to antisecretory treatment with
esomeprazole 20mg or placebo bid for 3 weeks.
The primary objective is to quantify tooth substance loss as well as changes in optical
reflectance and scattering of dental hard tissues with and without acid inhibition.
Secondary objectives are:
To compare standardised visual scoring with OCT quantification of reflux damage at the
different time points on different teeth.
To assess sex differences in OCT- quantified dental tissue loss.

Allergy to or other contraindication for treatment with esomeprazole. 8. Use of proton pump inhibitors in 2 weeks or other acid inhibitory drugs in 3 days before study inclusion. 9. Substantial change or planned change in dietary pattern, esp. diets within 2 weeks of study start and for the duration of the entire study. 10. Change or planned change in normal medication or use of herbal, mineral, vitamin preparations within 2 weeks of study start and until the end of the study. 11. Congenital dental defects. 12. Ongoing pregnancy or breast-feeding. |
