Spectrophotometric Analysis of Coronal Tooth Discoloration Induced by Tricalcium Silicate Cements in the Presence of Blood.

Introduction: New tricalcium silicate cements have been shown to induce less coronal discoloration. The purpose of this in vitro study was to evaluate the degree of color change induced by various silicate materials in the presence and absence of blood.

Methods: One hundred human extracted anterior single-canal teeth were sectioned to standardized root lengths, accessed, and instrumented.
