    Study Notes

    Hard Palate

    • Contains papilla rostrally for sense of smell and taste
    • Moveable fold of tissue overlying the hard palate
    • Connects to the pharynx
    • Smooth and free of papilla
    • Covers the alveolar bone that supports the teeth
    • Two bones create the hard palate
    • Defect in this bone causes a cleft palate
    • Infected and abscessed maxillary premolars or molars can cause periodontal disease

    Periodontal Disease

    • Thin film consisting of salivary proteins and glycoproteins
    • Protects and lubricates
    • Bacteria colonize and form a biofilm on the surfaces of the tooth (crown) which eventually becomes plaque
    • Calcium products crystallize on the surface of the teeth and mineralize the soft plaque
    • Takes approximately 2-3 days to form
    • Once bacteria & dental plaque is removed, inflammation of gingivitis disappears
    • Periodontitis is a non-inflammatory destruction of the endothelial barrier that protects the tooth’s supporting structures
    • As bacteria moves to towards the root, periodontal ligament and the alveolar bone are destroyed

    Stages of Periodontal Disease

    • Gingivitis: Mild gingival inflammation, no radiographic changes. Treatment involves dental cleaning
    • Early Periodontitis: Gingivitis with swelling, bleeding with probing, 25% attachment loss (sulcus depth). X-rays show loss of periodontal attachment (less than 25%). Treatment involves dental cleaning with subgingival curettage
    • Moderate Periodontitis: Gum recession or hypoplasia, 25-50% loss of attachment, furcation involvement, tooth mobility, 10-20% bone loss on radiograph, gingivitis with swelling and bleeding with probing. Treatment involves more extensive procedures.
    • Advanced Periodontitis: Gum recession or hypoplasia, 50% loss of attachment, furcation involvement, tooth mobility, over 30% bone loss on radiograph, gingivitis with swelling and bleeding with probing. Treatment involves extensive procedures.

    Periodontal Disease Notes

    • Not all plaque leads to periodontal disease; it depends on the immune response of the animal
    • All animals develop plaque, which always leads to periodontitis
    • Positioning of the pet for dental prophylaxis
    • Patient positioning for radiographs

    • Parallel Radiographic Technique: Used for teeth:

    • Bisecting Angle Radiographic Technique: Used for teeth:

    • Structures evaluated during an oral examination:

    Scaling

    • Scaler Tip and Water Flow:
      • Larger scaler tip requires more water
      • Newer scaler tip needs more power, and less power as it wears

    • Working End of the Instrument:

    • Curette Insertion:

    • Polishing:
      • It is always necessary to polish after scaling to remove any plaque left
      • Best deterrent to having plaque form again
    • Calcium:
      • Helps eliminate plaque and stimulates healing

    Instruments

    • Probe Increments and Type:

    • 1mm Loss of Scaler Tip:
      • Decreases efficiency but doesn’t need replacement until 3mm loss
