Abstract

Objectives: The aim of this study was to investigate the effect of erosion on direct tooth-coloured restorations and adjacent enamel/dentine under low and normal simulated salivary flow rates. Methods: Bovine enamel and dentine specimens were prepared (n = 16) and restored with the following materials: resin composite (FiltekZ250), resin-modified glass ionomer cement (Fuji II LC), high-viscosity glass ionomer cement (Fuji IX), and conventional glass ionomer cement (Fuji II). They were submitted to. in vitro erosion-remineralisation cycling simulating normal (0.5. ml/min) and low (0.05. ml/min) salivary flow rates, for 5 days. The restorative material, enamel and dentine substrates were assessed with optical profilometry for surface loss. Mixed-model ANOVAs were used for statistical comparisons (alpha. = 0.05). Results: Low-salivary flow significantly increased surface loss for all tested substrates (p
