During the follow-up period, what percentage of teeth with furcation involvement were lost?

The correct answer indicates that 31.6% of teeth with furcation involvement were lost during the follow-up period. This percentage underscores the significant impact furcation involvement has on tooth retention, highlighting its association with periodontal disease severity.

Furcation involvement signifies that the periodontal disease has progressed to a stage where it affects the bone and tissue surrounding the roots of multi-rooted teeth. In such cases, the periodontal support is compromised, making these teeth more susceptible to loss, especially if left untreated or inadequately managed. The 31.6% figure reflects data collected from clinical studies that examine tooth loss rates in patients with varying degrees of periodontal disease severity, particularly in relation to furcation involvement.

Understanding this statistic is crucial for practitioners, as it emphasizes the need for appropriate periodontal treatment and monitoring of patients with furcation involvement to prevent tooth loss. This information aids in patient management by stressing the importance of early intervention and consistent oral hygiene practices to maintain periodontal health.
