Table 2.
Comparison of the general condition according to periodontal status.
| PISA [mm2] < 300 | PISA [mm2] ≧ 300 | p-Value | |
|---|---|---|---|
| Age [years] | 69 (50, 75) | 71.5 (58, 79) | 0.48 |
| Sex [female %] | 55.5 | 10.4 | 0.07 |
| Number of teeth | 25 (22, 27) | 26 (22, 28) | 0.40 |
| HbA1c [%] | 5.6 (5.4, 5.9) | 5.8 (5.4, 6.4) | 0.24 |
| Blood glucose [mg/dL] | 110 (98, 127) | 112 (99, 175) | 0.25 |
| Probing depth [mm] | 2.2 (2.0, 2.4) | 3.0 (2.5, 3.3) | <0.0001 |
| Bleeding on probing [%] | 14 (8, 23) | 47 (35, 62) | <0.0001 |
| Leukocyte score in saliva | 59 (35, 77) | 77 (70, 89) | <0.0001 |
| Protein score in saliva | 42 (28, 65) | 58 (43, 83) | 0.0001 |
| Increased AST [%] | 48.2 | 52.9 | 0.62 |
| Increased ALT [%] | 35.3 | 47.0 | 0.20 |
| Increased GGT [%] | 10.8 | 29.4 | 0.0056 |
The subjects were divided into two groups according to the PISA using a cutoff value of 300 mm2. Cutoff values were also established for AST, ALT, and GGT; more than 20 U/L of AST, more than 20 U/L of ALT, and more than 50UI GGT were judged as high values. PISA, periodontal inflamed surface area; HbA1c, hemoglobin A1c; AST, aspartate aminotransferase; ALT, alanine aminotransferase; GGT, gamma-glutamyl transferase.
