The advantages of using the PSR system include early detection, speed, simplicity, cost-effectiveness, ease of recording, and risk management.
There are limitations when using the PSR system. As stated earlier, it is not intended to replace a full-mouth periodontal examination. Those patients who have received treatment for periodontal diseases and/or are in a maintenance phase of care should receive comprehensive periodontal examinations. There is also limited use of the PSR system in children. It is necessary to differentiate pseudo-pockets from true periodontal pockets with these younger patients. Landry and Jean reported that since the PSR does not measure epithelial attachment, the severity of periodontal disease may be underestimated with its use.5
