Medical emergencies are life threatening, albeit most emergencies take place in adults, serious complications can also develop in young children. Certain difference between adult and child cannot be overlooked such as physical, emotional & cognitive maturity and physiology like respiratory, cardiovascular and immune system. The American Academy of Pediatric recognizes emergency care for infants, adolescents and individuals with special health care needs as an essential duty of every dentist. Common medical emergencies encountered in children on dental chair are foreign body obstruction, syncope, asthma, seizure, anaphylaxis, anesthesia or sedation overdose. The American Dental Association's Principles of Ethics and Code of Professional Conduct states that "dentist shall be obliged to make reasonable arrangements for the care of their patients". Hence the pediatric dentist is obligated to have the necessary equipment, drug and knowledge to provide immediate and proper emergency therapy, when any medical emergency arise in the dental clinic. This book is a compilation of the reviews of medical emergencies in pediatric dental care and its management.
