If a patient has furcal involvement with class III mobility and poor plaque control, what is the prognosis?

• A. questionable
• B. good
• C. poor
• D. hopeless

Answer: (D)

In the context of periodontal disease, furcal involvement refers to the presence of periodontal defects that extend into the furcation area of a multirooted tooth. Class III mobility indicates significant mobility of the tooth, meaning the attachment between the tooth and surrounding supportive tissues is severely compromised. Poor plaque control is an important factor as it directly affects the health of the periodontal tissues.

When evaluating the prognosis of a tooth with furcal involvement, class III mobility, and poor plaque control, the prognosis is considered "hopeless." This classification indicates that the likelihood of maintaining the tooth long-term is minimal due to the severe loss of both bone support and periodontal health. Treatment outcomes are likely to be poor if the underlying causes, such as inadequate plaque control, cannot be effectively managed. In such cases, extraction may be the most appropriate outcome to prevent further complications.

Understanding these factors is crucial in planning treatment and discussing options with the patient, ensuring that expectations are managed appropriately in light of the dental condition presented.
