American Board of Orthodontics (ABO) Practice Exam

The diagnosis of ankylosed teeth is most effectively accomplished through angular bone defect analysis. Ankylosis refers to the fusion between the tooth root and the surrounding bone, which can lead to changes in the surrounding bone structure. This method involves assessing the bone levels and patterns around the tooth, which can reveal characteristic signs of ankylosis, such as a lack of normal periodontal ligament space or changes in the bony architecture.

While panoramic X-rays and clinical examinations can provide valuable information, they may not always clearly indicate ankylosis. A clinical exam can reveal mobility issues or sound differences when tapping the tooth, but it may not provide comprehensive insights into the underlying bone health. Thermal testing is generally used for pulp vitality tests and would not be informative regarding the dental socket or the condition of the tooth's connection to the bone. Therefore, angular bone defect analysis stands out as the most effective method for diagnosing ankylosed teeth, allowing practitioners to visualize the structural changes indicative of this condition.
