Staging
There are two dimensions in the process of assessing the stage of periodontitis in a patient: severity and complexity. Severity : The primary goal is to classify the severity and extent of destroyed and damaged tissue caused by periodontitis. This is done by measuring CAL by clinical probing and bone loss by radiographic examination. These measurements must include the number of teeth whose loss can be attributed to periodontitis. Complexity : The secondary goal is to determine the complexity involved in controlling the disease and managing the long-term function and aesthetics of the patient’s dentition. Scoring the stages : The severity score is based primarily on interdental attachment loss attributable to periodontitis (CAL) and marginal bone loss. It is assigned based on the worst-affected tooth. The complexity score is based on the complexity of treating the case. It considers factors including the presence of deep probing depths, vertical defects, furcation involvement, tooth hypermobility, drifting and/or flaring of teeth, tooth loss, ridge deficiency, and loss of masticatory function.
Stage I: Initial periodontitis
Stage II: Moderate periodontitis
Stage III: Severe periodontitis with potential for additional tooth loss
Stage IV: Advanced periodontitis with extensive tooth loss and potential for loss of dentition
