Units at a Glance

Unit 1: Medical Emergencies in the Dental Office

A medical emergency can occur at any moment in a dental office. Dental professionals must be trained to understand the signs of a dental emergency and know what actions are indicated. The quick response of dental team members can alter the outcome of a potentially life-threatening event. Proper training, along with relevant updates as necessary, should occur regularly within an office to ensure all team members understand their assigned roles during an emergency situation.

As long as there have been drugs, there have been those who misuse or overuse them. The history of drug abuse and addiction can be traced back for centuries. However, as common as drug addiction has been throughout time, America is currently in the midst of a significant opioid epidemic that has impacted millions of families and taken thousands of lives. Knowing about both the past and current state of the crisis is essential in dentistry, as patients are often prescribed opioids to manage their pain after dental procedures, and unfortunately, any initial exposure to opioids can lead to dangerous patterns of addiction. When dental assistants know the signs and symptoms of misuse, abuse, and addiction, they are better equipped to educate their patients and help keep them safe from developing unhealthy relationships with opioids and other drugs.
