Classification |
Glickman-
Grade i- 1. Incipient or early stage. 2. Suprabony pocket 3. Early bone loss may have occurred with an increase in probing depth. 4. No evident radiographic changes.
Grade ii- 1. Cul de sac lesion with a definite horizontal component. 2. A portion of alveolar bone remains attached to the tooth. 3. Radiographic changes may or may not be visible. (Furcation arrows are visible in some views).
Grade iii 1. Bone is not attached to dome of furcation 2. Through and through involvement 3. May not be probed In such cases add buccal and lingual horizontal probing depths This must be greater than buccolingual dimension of tooth. 4. Radiographic changes- radiolucent area in the crotch of the tooth.
Grade iv- 1. Interdental bone is destroyed and soft tissue has receded apically 2. Clinically visible furcation opening 3. Probe easily passes. |
