The American Dental Association Division of Legal Affairs appreciates Dr. Weinstocks thoughtful letter. The Legal Division wishes to emphasize that the precise requirements for informed consent will vary from jurisdiction to jurisdiction. For some procedures in some jurisdictions, oral consent may suffice, though a written consent is preferable if there is litigation inasmuch as you will have written evidence of the consent.
As Dr. Weinstock noted, the patient should consent, in some form or another, to every procedure. Members should consult with attorneys licensed to practice in their state for information on how informed consent is handled in their jurisdiction.
