Study Notes
Furcation Classification
- Class I: Curvature of concavity felt with the probe tip.
- Class II: Probe tip penetrates into the furcation but does not pass through completely.
- Class III: Probe passes completely through the furcation.
- Class IV: Probe passes through the furcation and entrance is visibly clear.
Furcation Access
- Mandibular (MD) molars have access points on buccal and lingual sides.
- Maxillary (MX) molars have access on median, distal, and facial surfaces.
- Maxillary first premolars have access on mesial and distal, as well as buccal and palatal roots.
Fenestration
- Defined as a "window" effect with bone loss on the facial or lingual sides of a tooth.
- Exposed root surface comes into contact with gingiva or alveolar mucosa.
- Distinguished from dehiscence by being bordered by alveolar bone at the coronal aspect.
Dehiscence
- Known as a "door," characterized by loss of alveolar bone on the facial side (rarely lingual).
- Creates an oval, root-exposed defect from the cementoenamel junction downwards.
- Defect size varies from one to two millimeters to the full length of the root.
- Key features include gingival recession, alveolar bone loss, and root exposure.
