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.
