Impact of Periodontal Disease on the Quality of Life of Diabetics Based on Different Clinical Diagnostic Criteria

Table 1

Description of clinical diagnostic criteria for periodontal disease.

Clinical diagnostic criteria	Description
(I) AAP	Presence of disease when a person has, at least, one tooth probing depth ≥ 4 mm and clinical insertion loss ≥ 4 mm at the same site [3].
(II) Beck	Attachment loss ≥ 5 mm in four or more sites and at least one of these sites with probing depth ≥ 4 mm [4].
(III) Machtei	Attachment loss ≥ 6 mm in two or more teeth and probing depth ≥ 5 mm in one or more sites [5].
(IV) Lopez	Four or more teeth with at least one site with probing depth ≥ 4 mm and insertion loss ≥ 3 mm [6].
(V) Albandar	Classifies periodontal disease as mild (1 or more teeth with probing depth ≥ 3 mm), moderate (1 or more teeth with probing depth ≥ 5 mm or 2 or more teeth with probing depth ≥ 4 mm), and severe (2 or more teeth with probing depth ≥ 5 mm or 4 or more teeth with probing depth ≥ 4 mm) [7].
(VI) Tonetti	Considers attachment loss ≥ 3 mm in two or more nonadjacent teeth or insertion loss ≥ 5 mm in 30% in of teeth [8].
(VII) Community Periodontal Index (CPI)	Considers the worst condition encountered in six sites evaluated and used the following four codes: 0 = healthy; 1 = absence of pockets, bacterial plaque retention factors, or bleeding following probing; 2 = depth as much as 3 mm and presence of bacterial plaque retention factors; 3 = pockets with probing depth between 4 and 5 mm; 4 = probing depth ≥ 6 mm [9]
