Table 1.
Characteristics of patients with Alzheimer’s disease (AD) and elderly controls.
| Basic Profile | Patients with AD | Elderly Controls |
|---|---|---|
| Sample size, N | 17 | 18 |
| Male: Female | 6: 11 | 6:12 |
| Age, years | 77.9 ± 10.5 | 65.2 ± 24.6 |
| CDR, score | 1.0 (0.5–2.0) | - |
| CDR-SB, score | 7.0 (3.0–12.0) | - |
| MMSE, score | 14 (6.0–21) | - |
| Decayed, Missing, and Filled Teeth (DMFT) index | 17 (12–26) | 21 (16–22) |
| Number of decayed teeth | 2 (1–3) | 2 (1–3) |
| Number of missing teeth | 10 (5–19) * | 5 (3–11) |
| Number of filled teeth | 4 (3–9) | 9 (4–12) |
| Dental plaque weight, g | 0.05 * (0.02–0.07) | 0.02 (0.02–0.04) |
* p < 0.05 by two-tailed t-test or Mann–Whitney U test, where appropriate. Number of missing teeth and dental plaque weight were significantly larger in the AD group than in the control group (* p < 0.05). Clinical Dementia Rating (CDR) score, CDR-SB (CDR–Sum of Boxes), and MMSE (Mini–Mental Status Examination) scores were listed in the AD group.
