    Study Notes

    Non-Carious Tooth Surface Loss (Tooth Wear)

    • Tooth wear is a significant factor affecting long-term dental health, impacting both young and older adults.
    • This necessitates better preventive and restorative approaches by dental professionals.
    • The main mechanisms of tooth surface loss are erosion, attrition, and abrasion.

    Mechanisms of Tooth Surface Loss

    • Erosion: Chemical dissolution of tooth substance without plaque.
    • Factors impacting erosion include:
      • Acids (intrinsic, exogenous): Gastric acid, dietary, environmental, and occupational acids.
      • Frequency of exposure.
      • pH/buffering.
    • Common erosive patterns:
      • Vomiting (palatal surfaces most affected).
      • Gastroesophageal reflux disease (GORD).
      • Rumination.
      • Eructation (burping).
      • Dietary intake (acids).
      • Drinking acidic beverages (labial surfaces).
      • Acidic sour candies.
    • Attrition: Tooth-to-tooth contact without food.
    • Factors impacting attrition:
      • Stress (chronic stress, "highly strung" individuals).
      • Distress.
      • Sleep disturbances.
      • Occlusal interferences (generally, not a direct significant factor).
    • This grinding action can lead to pathological damage (enamel flaking, cusp fractures) and tooth damage, particularly on anterior teeth.
    • Abrasion: Wear due to exogenous material friction.
    • Abrasive sources: food, toothbrushes, dentifrices, foreign objects.
    • Abrasion can be from hard foods, occupations, etc.
    • Food abrasion is less of a problem now due to food processing.

    Identifying Erosion

    • Micro-anatomical enamel features are lost leading to a "glazed" or "silky" appearance.
    • The teeth lose contours with curved enamel areas flattening.
    • Scooped dentine.
    • The presence of wedge-shaped non-carious cervical lesions suggests erosion.

    Identifying Attrition

    • Presence of facets (flattened areas).
    • Enamel flaking/cusp fractures.
    • Craniomandibular disorders.

    Identifying Abrasion

    • Asymmetric wear ("notch").
    • Scooped dentine (incisal/occlusal surfaces).
    • Lack of sensitivity.
    • Impacted by associated erosion.

    Minimum Intervention for Tooth Surface Loss Treatment

    • Identify the mechanism(s).
    • Assess if the mechanism(s) are active.
    • Determine why the patient has this problem (lifestyle, medications, etc.).
    • Develop a preventive/monitoring program tailored to the patient.
    • Perform minimum intervention where needed, preserving tooth structure.
    • Ensure patient assumes responsibility for preventive treatment success.
