The definitions for levels of the CDC/AAP index are: No periodontitis, no evidence of mild, moderate, or severe periodontitis; Mild periodontitis, ≥two interproximal sites with AL ≥3 mm and ≥two interproximal sites with PD of ≥4 mm (not on same tooth) or one site with PD ≥5 mm; Moderate periodontitis, ≥two interproximal sites with AL ≥4 mm (not on same tooth) or ≥two interproximal sites with PD ≥5 mm (not on same tooth); Severe periodontitis, ≥two interproximal sites with AL ≥6 mm (not on same tooth) and ≥one interproximal site with PD ≥5 mm.
The definitions for levels of the European Index are: No periodontitis, no evidence of incipient or severe periodontitis; Incipient periodontitis, presence of proximal attachment loss of ≥3 mm in ≥two non-adjacent teeth; Severe periodontitis, presence of proximal attachment loss of ≥5 mm in ≥30% of teeth.
