Since the sharing of patient information is restricted to specific allowances, it can be confusing. But in short terms, it is usually when the patient is at risk of harm to themselves or others, as well as subpoena and judgement orders that require specific patient information, such as an X-ray of the patient’s teeth or their oral history. Your dental practice may not be related to “patient at risk” details as you have no medical information in relation to it, but the subpoenas and judgements will apply. It may not occur much in the dental field, but it is possible and is important to know. This is just one example of legally sharing patient information when it otherwise would not be acceptable.
