What should be completed and updated at each patient visit?

Updating the patient's medical health history form at each visit is crucial because it ensures that the dental team is aware of any changes in the patient's health status that could affect their dental treatment. This information is vital for safe and effective care, as it provides insights into allergies, medications, previous medical conditions, and any new health issues that may arise.

By consistently reviewing and updating the medical history, the dental healthcare providers can make informed decisions about the patient's treatment plan. It fosters a comprehensive understanding of the patient's overall health, allowing for necessary adjustments in dental care to accommodate any new medical information. This practice not only enhances patient safety but also supports a higher standard of care within the dental practice.

While the other options—insurance information, treatment plans, and billing statements—are also important, they do not require the same level of ongoing updates or direct impact on patient safety and treatment outcomes as the medical health history form does.
