    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.
