Statement Of Problem: There is little agreement in the dental literature as to how much color difference constitutes an acceptable shade mismatch or how much color difference is considered perceivable to observers. Most studies attempting to determine perceptibility and acceptability of tolerances for shade mismatches have been conducted under in vitro conditions that are not applicable to clinical scenarios.
Purpose: The goal of this study was to determine valid acceptability and perceptibility tolerances for shade mismatch in an actual clinical scenario using spectroradiometric instrumentation.
Cardiovascular diseases are the leading cause of death in the United States and most other Western countries. In the United States alone, more than 1 million annual deaths and as many as three times that number of serious consequences can be attributed to these conditions. To provide care to patients with cardiovascular disease, oral health care providers must understand the disease, its treatment, and its impact on the patient's ability to undergo and respond to dental care.

When the blood volume becomes greater than the limited volume capacity of the vascular system, the patient develops hypertension. When the myocardium does not get enough oxygen because of coronary artery disease, the patient will experience angina pectoris.
