What is the typical treatment for Class 2 furcal defects?

• A. Extraction
• B. Root canal therapy
• C. Periodontal surgery
• D. Guided tissue regeneration

Answer: (D)

In the management of Class 2 furcal defects, guided tissue regeneration (GTR) is typically the most appropriate treatment option. Class 2 furcal defects indicate a moderate level of periodontal bone loss that affects the furcation area of a multi-rooted tooth. GTR is aimed at promoting the regeneration of periodontal tissues, including bone, cementum, and periodontal ligament, by utilizing barrier membranes that prevent the ingrowth of non-osteogenic tissues.

This technique has the potential to effectively restore the architecture of bone around the affected tooth, thus improving the clinical outcomes, such as enhancing the tooth's stability and increasing the likelihood of maintaining it in the long term. The use of GTR can lead to improved periodontal health, as it focuses not only on the treatment of the defect but also on the regeneration of the surrounding support tissues.

While other treatments like extraction or root canal therapy might be appropriate in different contexts, they do not address the specific need for tissue regeneration in the case of Class 2 furcal defects. Extraction would be considered when the tooth is non-restorable or deemed unsalvageable, while root canal therapy would address endodontic issues rather than periodontal ones. Periodontal surgery might help in managing the defect but does not
