It is important to be able to identify oral pathology and anomalies. It is equally important to correctly record the pathology on dental charts. The indices most commonly evaluated are gingivitis, probe depth, gingival recession, furcation involvement, mobility and periodontal attachment. These indices are the factors along with radiographs that are involved in grading periodontal disease. Other types of pathology include stomatitis, chronic alveolar osteitis, tooth resorption, fractures, oral masses and malocclusions.
