Introduction

During the past 25 years clinicians have seen an exponential increase in the number of medically compromised patients who seek dental care and because of advances in dental research and education oral healthcare providers perform increasingly more complex procedures on these patients. As a result, clinicians can expect to face situations during the perioperative period that may threaten the physical well-being of patients. The risk of perioperative medical complications depends on procedure-specific and patient-specific factors.
