ALTERNATE FORMS,
In comparison to using solely frequency or severity score,
OIDPscore was a better predictor for DMFT and number of sextants with
deep periodontal pockets.
Therefore, the multiplication score would still be presented in the final version of OIDP. However,since the improvement of OIDP compared to either frequency or severity score used alone was not statistically significant in the prediction test,
using one of them to improve simplicity and efficiency can be considered. As frequency and severity scores had similar predictive powers, frequency should be a better representative single choice because of its better reproducibility.
