Table 1.
Classification of oral inflammatory burden. Oral inflammatory burden can be assessed by recording different indices, such as the PIBI, TDI, and PTI, as shown in the next tables [16,24].
| PIBI = Nmod PPD + 2 Nadv PPD | ||
| Nmod = number of sites with moderate periodontal lesions (4 ± 5 mm) | ||
| Nadv = number of sites with advanced periodontal lesions (≥6 mm) | ||
| PPD = periodontal pocket depth | ||
| Determination of Periodontal Inflammatory Burden (PIBI, 28 teeth). | ||
| Determination of Total Dental Index (TDI, 32 teeth). | ||
| Oral Disease | Score | |
| Caries | No caries lesions | 0 |
| 1 ± 3 caries lesions | 1 | |
| 4 ± 7 caries lesions or no teeth in maxilla or mandible | 2 | |
| 8 caries or radix or no teeth | 3 | |
| Periodontitis | 4 ± 5 mm deep periodontal pocket | 1 |
| 6 mm deep periodontal pocket | 2 | |
| Pus in gingival pocket | 3 | |
| Periapical lesions | 1 periapical lesion or vertical bone pocket or both | 1 |
| 2 periapical lesions | 2 | |
| 3 periapical lesions | 3 | |
| Pericoronitis | Absent | 0 |
| Present | 1 | |
| Determination of Panoramic Tomography Index (PTI) | ||
| PTI = Periapical lesions + lesions caused by tertiary caries + vertical bone pockets + radiolucent areas at the furcation + lesions caused by pericoronitis formed | ||
