Influence of a soft drink with low pH on enamel surfaces: an in vitro study.

Introduction: The purpose of this study was to investigate, in vitro, the short-term effect of a soft drink (Coca Cola, Coca Cola Company, Atlanta, Ga) with low pH on enamel surfaces at different levels of intake. Effects on labial and palatal surfaces were also compared.
