Veneer contaminated with blood during cementation (A,B). If the contamination is low, it will appear late. However, if the contamination is high, it will immediately occur. A thinner veneer correlates to an increased chance of blood contamination. In this case, the solution was used to cut the veneer, and it was replaced with a new veneer. The bleeding needed to be controlled using astringent solutions, such as aluminum chloride. The photos were sourced from the School of Dentistry, University of Alabama, Birmingham, AL, USA.
