What type of courses can be used for the required dental assistant continuing education?

The correct choice highlights the flexibility and variety of options available for continuing education for dental assistants. Continuing education is essential for dental professionals to stay updated on the latest practices, techniques, and regulations in dentistry. Providing multiple methods of learning—such as self-study, lectures, and internet courses—allows dental assistants to choose formats that best fit their schedules, learning styles, and professional needs.

Self-study can involve reading materials or engaging with other resources at one's own pace, while lecture-based learning typically involves attending seminars or workshops where knowledge is imparted through presentations. Internet courses offer the additional benefit of accessibility, allowing participants to learn from virtually anywhere, making education more convenient.

Limiting continuing education to only one format, such as in-person lectures or internet-based courses, would restrict the learning opportunities and could hinder professional development. Thus, the diverse options provided in the correct answer ensure that dental assistants can fulfill their education requirements effectively while adapting to their individual preferences and situations.
