As a previously on-the-job trained dental assistant and orthodontic assistant, and now an RDH who chose to take my CDA exam recently. I am well aware of the education required. I, without a doubt, support this.  Every dental assistant (and personnel) is the responsibility of the dentist that hired them, yes. However, most DA's are usually trained by other dental assistants, and unfortunately, the ones providing the training for day-to-day tasks and infection control are not always qualified to do so. Telling someone "how" to do a task is much different than someone understanding "why" they are doing the said task. Infection control is of the utmost importance for safety. You can never be over-educated so this will not harm anyone. It will provide consistency for offices and dental assistants. It will not only protect the public but also the dental assistants themselves.
