**Question:** What treatment should not be required for the patient with grade II furcation involvement?

**Core Concept:** Grade II furcation involvement refers to the involvement of the furcal papilla by the periodontal disease, which results in inflammation and destruction of the furcal papilla. Treatment options for furcation involvement include non-surgical periodontal therapy and surgical therapy, depending on the extent of the disease and the patient's response to non-surgical therapy.

**Why the Correct Answer is Right:** In the case of grade II furcation involvement, non-surgical periodontal therapy is usually sufficient to manage the disease process. This includes plaque control, scaling and root planing, and local antimicrobial therapy. In some cases, adjunctive therapies like local drug delivery systems (e.g., antibiotics, growth factors) may be employed to enhance the outcome of non-surgical therapy. The treatment is less invasive and less expensive than surgical therapy, which is typically required for more severe forms of furcation involvement.

**Why Each Wrong Option is Incorrect:**

A. Surgical therapy: Although surgical therapy may be necessary for more severe forms of furcation involvement, it is not required for grade II furcation involvement, as non-surgical therapy is usually sufficient.

B. Local drug delivery systems: While these may be employed as adjuncts to non-surgical therapy, they are not a standalone solution for grade II furcation involvement and should not be the first-line treatment.

C. Plaque control: Although plaque control is essential for all periodontal patients, it is not a treatment modality for grade II furcation involvement but rather a preventive measure.

D. Localized antibiotics or growth factors: Similar to B, these may be used as adjuncts to non-surgical therapy, but are not a standalone solution for grade II furcation involvement.

**Clinical Pearl:** In the management of grade II furcation involvement, a thorough and regular plaque control is essential. However, the primary treatment modality involves non-surgical periodontal therapy, including scaling and root planing, and local drug delivery systems (e.g., antibiotics, growth factors) may be used as adjuncts to enhance the outcome, but are not the primary treatment. Surgical therapy is usually only required for more severe cases of furcation involvement.
