Final answer:
True, a medical emergency in the dental office must be documented in detail, but the need to file a report with local EMS varies by region and is not always required.
Step-by-step explanation:
The statement that a medical emergency in the dental office must be documented with all of the pertinent details is true. It is essential to record what happened, the treatment provided, and the patient's condition upon leaving the office. However, the requirement to file a report with the local Emergency Medical Services (EMS) can vary by region and is not a universal mandate. In most cases, it is advised to follow local regulations and office policies related to the reporting of medical emergencies.
