What kind of therapy would scaling and root planing be categorized under?

Scaling and root planing is categorized as Phase I therapy because it encompasses non-surgical periodontal treatment aimed at removing plaque and calculus from tooth surfaces to promote healing of the periodontal tissues. This initial phase of therapy is crucial in managing periodontal disease, as it helps to reduce inflammation, deepen pockets, and ultimately improve the overall periodontal health of the patient.

Phase I therapy focuses on nonsurgical interventions that help get the disease under control before considering more advanced procedures. This approach often involves patient education, improved oral hygiene practices, and addressing risk factors, along with the mechanical debridement provided through scaling and root planing.

In contrast, the other phases—Phase II typically involves surgical interventions, Phase III may involve prosthetic rehabilitation, and Phase IV usually focuses on maintenance therapy—are distinct from the initial efforts made in Phase I therapy. Thus, recognizing scaling and root planing as Phase I therapy is vital for understanding the sequence and classification of periodontal treatment approaches.
