For my signature assignment in Dental Hygiene Theory I, I gave a presentation on facial emphysema. Prior to this, I had never heard of the condition, so I was grateful to have received this topic. Through researching and presenting on it, I gained a great deal of knowledge. I explored various aspects of the condition, including its risk factors, symptoms, prevention strategies, minimization techniques, and treatment options. Understanding facial emphysema is crucial for dental hygienists, as it is more likely to occur in patients with periodontal disease and can potentially lead to life-threatening complications.
