    Study Notes

    Tooth Wear

    • Tooth wear is the progressive loss of enamel, dentine, and cementum due to physical or chemical-physical processes.

    Aetiological Factors of Tooth Wear

    • Erosion: The chemical loss of tooth tissue caused by acids not from oral bacteria.
      • Extrinsic acids: Acidic drinks, multiple fruit intake between meals, holding drinks in the mouth, frequent acid attacks.
      • Intrinsic acids: Stomach acids (hydrochloric acid), Gastroesophageal reflux disease (GORD), eating disorders, frequent vomiting, pregnancy (severe morning sickness).
      • Free sugars: Added to foods and drinks.
    • Attrition: The physical loss of tooth tissue due to tooth-to-tooth contact (resulting in flatter surfaces).
      • Causes: Bruxism, malocclusion.
    • Abrasion: The physical loss of tooth tissue by factors other than teeth (often co-exists with erosion).
      • Causes: Hard diet, over-brushing, abrasive toothpaste, retainers/dentures, nail-biting, piercings, pen chewing, job-related activities.
    • Abfraction: Loss of tooth structure in the cervical region due to occlusal and cervical forces.

    Significance of Tooth Wear for Oral Health

    • Increased lifespan and prevalence of modern diets and lifestyles impact all ages.
    • Significant impact on patients, causing difficulty in early detection and systematic recording.

    Gingival Recession

    • Definition: Displacement of the gingival margin below the cemento-enamel junction, exposing root surface.

    Aetiological Factors of Gingival Recession

    • Mechanical:
      • Toothbrush trauma.
      • Traumatic incisor relationship (lower incisors impacting on upper incisors).
      • Foreign body trauma (piercings).
      • Abnormal frenum attachments.
      • Iatrogenic damage (power-driven scalers).
    • Inflammatory:
      • Gingival biotype (friable tissue).
      • Periodontal disease (apical migration).
      • Smoking (increased periodontal disease risk).
      • Poor marginal restoration fit (plaque, periodontal disease).
      • Orthodontic tooth movement (recession in rapid treatment with thin biotype).

    Oral Health Impact of Gingival Recession

    • Dentin hypersensitivity: Exposed dentin.
    • Aesthetics: "Black triangles" (visible root).
    • Root caries: Less mineralised root surface.
    • Poor plaque stagnation.
    • Reduced patient confidence.

    Measurement and Monitoring of Gingival Recession

    • Measured from the cemento-enamel junction (CEJ) to the gingival margin.
    • Miller's Classification (classifies recession severity and associated bone loss):
    • Class I: Recession not to mucogingival junction, no bone or soft tissue loss.
    • Class II: Recession to or beyond mucogingival junction, no bone or soft tissue loss.
    • Class III: Recession to or beyond mucogingival junction, with bone or soft tissue loss above apical recession margin.
    • Class IV: Recession to or beyond mucogingival junction, with loss of interdental bone or soft tissue at or below recession level.
    • Clinical Examination: Photos, measurements, patient education.
    • Monitoring: Patient adjustment of habits, periodontal stabilisation, or no intervention until stabilisation.

    Treatment Modalities for Gingival Recession

    • Periodontal treatment.
    • Desensitising agents.
    • Gingival veneers.
    • Composite restorations.
    • Referral for surgical intervention: Gingival grafts.
