Step-by-step explanation:
The dental permit categories created by the Dental Board of California on January 1, 2010, are: 1) Dental Sedation Assistant and 2) Orthodontic Assistant.
An explanation of these roles includes responsibilities that relate directly to patient care within a dental practice. A Dental Sedation Assistant is involved in assisting with the administration and monitoring of sedation, improving patient comfort and safety during dental procedures. On the other hand, an Orthodontic Assistant works closely with orthodontists, helping with procedures that align and straighten teeth, and is trained in specific skills relating to braces and other orthodontic appliances.
Both positions require special training and certification to ensure that practitioners are competent in their respective specialties and are able to provide the highest level of care to patients in California.
