In a root resection, which root should typically be selected for removal?

In the context of a root resection, selecting the root with the least remaining bone support for removal is a critical decision. This is because a root that has diminished bone support is more likely to compromise the overall periodontal health and stability of the tooth. The underlying principle in periodontal therapy, especially when considering surgical intervention like root resection, is to retain as much periodontal support as possible to maintain the tooth's function and health.

When a root is poorly supported by bone, it can lead to further periodontal issues, including persistent mobility, infection, and the potential loss of additional teeth. By removing the root with the least bone support, the remaining roots can benefit from enhanced stability, leading to improved periodontal health and retention of the tooth.

In other scenarios, such as considering dental caries, accessibility or the position relative to the gum line, those factors may influence decision-making but do not directly address the fundamental principles of periodontal health and support. Therefore, while those roots might present other challenges, prioritizing the removal of a root with poor bone support is key to ensuring the long-term viability of the remaining tooth structure.
