An accurate medical history is the most useful information a clinician can have when deciding whether a patient can safely undergo planned dental therapy. The dentist must also be prepared to predict how a medical problem will alter a patient’s response to planned anesthetic agents and dental surgery. If obtaining the history is well done, the physical and laboratory examinations ofa patient usually play relatively. minor roles in the presurgicalevaluation. The standard format used for recording the results of medical histories and physical examinations is illustrated in Box 1-.1.
The medical history interview and the physical examination should be tailored to each patient, considering the patient’s medical problems,· age, intelligence, and lifestyle; the complexity of the planned procedure; and the anticipated anesthetic methods.
