Long-term Results After Systematic Periodontal Therapy

Assessment of Gingival Bleeding Index and Plaque Control Record, re-instruction and re-motivation to effective individual plaque control, professional tooth cleaning, application of a fluoride gel. Twice a year a periodontal charting with probing pocket depths (PPD) and vertical attachment Level (PAL-V) are obtained at 6 sites per tooth. Thirty seconds after probing bleeding on probing (BOP) is recorded. Sites exhibiting PPD = 4 mm and BOP as well as sites with PPD \>/= 5 mm are scaled subgingivally. Assignment of SPT intervals is performed according to the periodontal risk assessment (PRA).
