Study Notes
Alveolar Bone: Structure and Function
- Alveolar bone, also called alveolar process, is only present where there are teeth.
- It's formed in relation to teeth.
- It plays a crucial role in supporting teeth and features a continuous rapid remodeling process due to eruption and mastication.
- The height of the cemento-enamel junction to bone crest is between 1 and 2mm
- Its function is to support teeth with a strong attachment, protect the tooth structure, act as a shock absorber, and provide attachment through Sharpey's fibers.
Alveolar Bone: Health to Disease
- A healthy alveolar bone has a height of 1 to 2mm between the cemento-enamel junction and the alveolar bone crest.
- This height is a key indicator of periodontal health.
- With a healthy periodontium, there is no pocketing around the tooth.
- Periodontitis is a disease that destroys the supporting structures of the teeth, including the alveolar bone.
- In periodontitis, the alveolar bone resorbs, or deteriorates, leading to increased pocket depth, tooth mobility, and eventual tooth loss.
- Two common defects in alveolar bone are dehiscence and fenestration.
Dehiscence
- Dehiscence is a defect that involves the loss of alveolar bone, leaving the root surface exposed.
- It can happen with trauma or recession, often resulting in the tooth moving forward and becoming sensitive.
Fenestration
- Fenestration is the loss of alveolar bone that exposes the tooth root on the facial or lingual surfaces.
- It's usually a result of trauma and can be a common finding.
Radiographic Relevance
- Radiographic assessment is key for diagnosing periodontitis, as it allows for visualization of bone loss and other abnormalities.
- Understanding the radiographic anatomy is important for forming a proper diagnosis and treatment plan.
Periodontal Disease in Detail
- Pocket depth is an indicator of the health of the gum tissue (gingiva) and surrounding bone structures.
- A healthy gum tissue is firmly attached to the tooth, maintaining a pocket depth of 1-2mm from the cemento-enamel junction (CEJ) to the alveolar bone crest.
- With periodontal disease, bacteria accumulate in the pocket, leading to inflammation and the deterioration of the supporting tissues (gingiva, cementum and alveolar bone).
- The bone resorption results in the deepening of the pockets and subsequent tooth mobility.
- Radiographic images are essential to visualize the extent of bone loss and guide treatment with appropriate interventions to address the affected areas.
