I am a dentist who recently was advised by my RDH staff that a 6 month period
always exists between a heart attack and the patient's prophylaxis. This was taught in their school. Until now, for 31 years, I have relied on the advisement, case by case, of the patient's MD and also the evaluation that we make of the patient's health and periodontal condition prior to the appointment. Sometimes we wait a few months, sometimes we have seen a patient only weeks after an event.
