Class 2 mobility indicates what degree of movement?

Class 2 mobility indicates a moderate degree of mobility in a tooth, which is characterized by movement greater than 1mm but less than 2mm in a horizontal direction. This classification is part of the periodontal assessment used to evaluate the stability of teeth and the health of the supporting periodontal tissues.

Understanding tooth mobility is essential in dental hygiene as it helps in diagnosing periodontal issues. When a tooth exhibits moderate mobility, it suggests that there may be some degree of periodontal disease affecting the supporting structures, such as the bone and gingiva. This information is vital for planning appropriate treatment strategies and monitoring the health of the periodontal tissues.

In contrast, slight mobility indicating movement up to 1mm is recognized as Class 1 mobility, while severe mobility in multiple directions corresponds to Class 3. No mobility indicates a healthy tooth firmly anchored in the alveolar bone and classified as Class 0. Knowing these classifications allows dental professionals to assess the periodontal condition effectively and make informed decisions about patient care.
