Which phase of dental therapy typically includes maintenance and professional dental hygiene therapy?

The phase of dental therapy that includes maintenance and professional dental hygiene therapy is typically referred to as Phase IV therapy. This phase focuses on the long-term management of periodontal health following initial treatment and any necessary corrective procedures. It aims to prevent the recurrence of periodontal disease through regular professional cleanings and ongoing monitoring of the patient's periodontal condition.

In Phase IV therapy, patients participate in a maintenance program that often includes more frequent dental visits, the implementation of personalized home care routines, and education on factors that contribute to periodontal health. The goal is to sustain the improvements achieved in earlier phases of therapy and to support the patient’s overall oral health.

In contrast, the other phases, such as Phase I, II, and III, focus on initial assessments, active treatment for periodontal disease, and any necessary surgical interventions or rehabilitative care, rather than the ongoing maintenance aspect highlighted in Phase IV.
