Which of the following is part of the dental hygienist's responsibilities?

• A. Scheduling patient appointments
• B. Performing radical surgeries
• C. Cleaning teeth and taking X-rays
• D. Designing dental equipment

Answer: (C)

The responsibility of cleaning teeth and taking X-rays is a fundamental aspect of a dental hygienist's role. Dental hygienists are specifically trained to perform prophylactic treatment, which includes the removal of plaque and tartar from teeth, and providing scaling and polishing procedures to maintain oral health. They also have the skills needed to take radiographs (X-rays) to help diagnose dental issues, all of which are essential for patient care and maintaining optimal oral hygiene practices.

In contrast, scheduling patient appointments and designing dental equipment, while important in the overall context of a dental practice, do not fall under the specific scope of practice for dental hygienists. Additionally, performing radical surgeries goes beyond the professional responsibilities of hygienists, as that task typically requires a dentist or oral surgeon with advanced training and certifications. Thus, the correct answer not only aligns with the defined duties of a dental hygienist but also highlights their critical role in preventive care within the dental team.
