California Registered Dental Assistant (RDA) Written Practice Exam

Curved crown and bridge scissors are the best tool for trimming or contouring a stainless steel crown because they are specifically designed for this purpose. Dental drills and lasers may also be used, but they carry a higher risk of damaging the crown or causing discomfort to the patient. Straight scissors are not recommended as they can easily slip and cause injury to the patient. It is important to use the appropriate tools and techniques to ensure a successful procedure.
