What action constitutes practicing Dental Hygiene?

Practicing Dental Hygiene encompasses a variety of clinical procedures aimed at maintaining and promoting oral health. Removing accumulated matter, tartar, or deposits is a fundamental skill of dental hygienists, as it directly impacts a patient's oral hygiene and overall health. This process, often referred to as prophylaxis, is essential for preventing periodontal disease and cavities.

Additionally, smoothing roughened root surfaces is a critical aspect of dental hygiene practice, especially in patients with periodontal disease. This technique, known as root planing, helps to eliminate bacteria and promote healing in the gums, making it an integral part of periodontal therapy.

Both actions—removing accumulated matter and smoothing root surfaces—are key components of dental hygiene and are performed as part of regular patient care to ensure optimal oral health. Therefore, the correct answer accurately reflects the scope of practice for dental hygiene professionals.
