Periodontics · single question

In the staged sequence of comprehensive periodontal therapy, nonsurgical cause-related therapy (scaling/root planing, oral hygiene instruction) is generally performed:

After any surgical periodontal therapy
Before surgical intervention is considered, as the initial phase of treatment, with re-evaluation determining the need for further (surgical) therapy
Only after extraction of all periodontally involved teeth
Simultaneously with implant placement only

Show answer and explanation

Correct answer: B. Before surgical intervention is considered, as the initial phase of treatment, with re-evaluation determining the need for further (surgical) therapy

Phase I (nonsurgical, cause-related) therapy comes first, addressing plaque/calculus and reinforcing home care. Re-evaluation after healing determines whether residual disease (pockets, inflammation) warrants surgical (Phase II) therapy.
