How was the periodontal risk score determined to be accurate?
The risk score was shown to be accurate and valid by comparing the actual periodontal status of 523 subjects followed for 15 years to a risk score calculated by PreViser. The outcome measures included mean bone loss, percentage of sites with bone loss, percent of tooth loss and percentage of subjects with tooth loss.The association between the risk score and actual periodontal deterioration observed over a period of 15 years was unusually strong with p values ‹0.0001.
