Various diagnostic procedures that can be used to identify perio endo lesions
| Visual examination | |
| Soft Tissues | |
| Inflammation | |
| Ulcerations | |
| Sinus tracts | |
| Teeth | |
| Caries | |
| Defective restorations | |
| Abrasions | |
| Cracks | |
| Fractures | |
| Discolorations | |
| Palpation | |
| Periradicualr abnormalities | |
| Cannot differentiate between endodontic and periodontal lesion | |
| Compare with control teeth | |
| Percussion | |
| Periradicular inflammation | |
| Compare with control teeth | |
| Mobility | |
| Loss of periodontal support | |
| Fractured roots | |
| Recent trauma | |
| Periradicular abscess | |
| Radiographs | |
| Periradicular bone resorption of endodontic origin - not effective | |
| Bone loss due to periodontal disease - effective | |
| Pulp vitality testing | |
| (Cold test, Electric test, Blood flow tests, Cavity test) | |
| Abnormal response – Degenerative changes | |
| No response – Pulp necrosis | |
| Moderate transient response – Normal vital pulp | |
| Quick painful response – Reversible pulpitis | |
| Lingering painful response – Irreversible pulpitis | |
| Pocket probing | |
| Probing depth | |
| Clinical attachment level | |
| Sinus tracking | |
| Fistula tracking | |
| Semi rigid radioopaque material (gutta percha) | |
| Cracked tooth testing | |
| Transillumination | |
| Wedging | |
| Staining |
