In Vivo Quantification of Dental Demineralisation Using OCT With and Without Esomeprazole

Summary

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.
