Evaluation of a New Self-reported Tool for Periodontitis Screening

Patients took part in the questionnaire and were examined using the PSI (periodontal screening index).

The PSI scores (0 to 4) were recorded: score 0=healthy, score 1=bleeding, score 2=supra-/subgingival calculus, score 3=probing depths from 3.5mm to max. 5.5mm, score 4=probing depths greater than 5.5mm. Only the highest finding was noted for each sextant. Persons with findings of code 0 to code 2 were classified as non-periodontitis persons (group 1), whereby codes 3 and 4 were considered a probable periodontitis persons (group 2).
