What type of bone resorption occurs in an uneven oblique direction affecting only one tooth?

Intrabony defect refers to a type of bone loss that occurs in a localized area around a tooth, specifically affecting the supporting alveolar bone. This condition manifests as an uneven oblique resorption pattern that can create a specific defect around a single tooth. Such a defect is characterized by bone loss that is confined to the area immediately surrounding the tooth and may have varying depths and angles, often impacted by factors like periodontal disease.

In contrast, horizontal bone loss typically results in a uniform reduction of the bone height around multiple teeth, leading to a more generalized pattern of resorption. Vertical bone loss, while it also suggests a localized pattern, usually describes a more pronounced and rapid loss that is typically seen along the natural contours of the bone. Peripheral bone loss generally indicates bone loss that occurs along the outer layers of the bone or may impact more broadly around several teeth, rather than focusing on a singular tooth.

Intrabony defects are significant in periodontology as they can lead to periodontal pockets and increased susceptibility to further periodontal disease, necessitating targeted treatment strategies for management. Understanding the specific nature of these defects is crucial for devising appropriate interventions during periodontal therapy.
