What classification includes recession types categorized as deep or shallow, wide or narrow?

The classification that includes recession types categorized as deep or shallow, wide or narrow is known as the Sullivan and Atkins classification. This system specifically addresses the varying degrees of gingival recession, focusing on quantifiable aspects such as the depth and width of the recession. By categorizing gingival conditions in this manner, it allows clinicians to more accurately describe the severity and extent of recession, which can be crucial for treatment planning and predicting outcomes in periodontal therapy.

In contrast, the Miller classification primarily classifies gingival recession based on the extent of underlying support and involvement of the mucogingival junction, without emphasizing the measurable dimensions of recession. The GTR (Guided Tissue Regeneration) classification pertains to procedures and techniques for promoting regeneration, while the furcation involvement classification focuses on the presence and extent of periodontal disease in the furcation areas of multi-rooted teeth. These classifications serve different purposes in periodontal assessment and treatment, emphasizing why Sullivan and Atkins is the most appropriate choice for this question.
