Periodontal index PI peri
PDI Ramfjord teeth
Extent and Severity Index ESI • Give information about extent and severity of the disease • Doesn’t asses gingival inflammation, but estimates the PAL
Periodontal Screening and Recording system PSR • Specially designed probe • 0.5 mm ball tip • Colored from 3.5 t0 5.5 • The mouth is divided in sextants • 6 measurements around each tooth • With other findings, the deepest pocket in the sextant estimate the PSR Grade • Grade 0 to 4 and Grade * for each sextant
Indices versus clinical findings Furcation involvement
Furcation involvement • Grade I: incipient involvement • Grade II: partial bone loss (Cul De Sac) • Grad III: total bone loss with through-and through opening of the furcation • Grade IV: similar to III with gingival recession exposing the furcation.
