Dental Assisting Exam Review
Course Introduction
Dental Assisting introduces students to the foundational knowledge and hands-on skills required to support dentists in clinical and administrative settings. The course covers essential topics such as dental anatomy, infection control, patient care procedures, radiography, sterilization techniques, and chairside assisting during various dental treatments. Emphasis is also placed on effective communication, ethical practices, and the role of the dental assistant in maintaining a safe and efficient dental environment. Through laboratory exercises and simulated experiences, students gain practical experience to prepare for entry-level positions in dental healthcare teams.
