Porcelain veneers as an alternative for the esthetic treatment of stained anterior teeth: clinical report.Quintessence Int. 2005 Mar; 36(3):191-6.QI

This article describes a technique in which discolored teeth were masked in a conservative and esthetically pleasing way with feldspathic porcelain veneers.
