Study Notes
Tooth Wear and Sensitivity
- Pulpits and vitality loss can result from tooth wear.
- Uneven wear occurs in one dental arch compared to the other.
- Inability to make incisal or occlusal contact during jaw excursions can indicate significant wear.
- Reduced incisor length creates a disproportionate appearance between length and width.
- Restorative procedures can protect teeth, improve function and aesthetics but will not stop ongoing wear.
- Like dental caries, restoration serves as a temporary solution without addressing the underlying cause.
Diagnosing and Monitoring Tooth Wear
- Diagnosis of tooth wear can be performed easily when teeth are clean and dry.
- Differentiating acceptable wear from pathological levels is challenging and age-dependent.
- A single examination does not determine the wear's progression speed; regular study models help assess changes and effectiveness of preventive measures.
- Classification of non-carious tooth defects includes: Attrition, Abrasions, Demastication, Erosion, Abfraction, Trauma & Fracture, Acquired Developmental Conditions, and Hereditary Conditions.
Attrition
- Defined as the mechanical loss of tooth structure (enamel and dentin) due to normal functional forces between contacting teeth.
- Process begins at tooth eruption and persists through normal oral functions like eating and speaking.
- Clinical signs vary; wear sites are primarily on occlusal surfaces but can also occur on proximal, labial, or lingual surfaces.
- Flattening, faceting, and saucering characterize the appearance of attrition.
- Hypertrophic masseter muscles may indicate bruxism, which accelerates wear.
Erosion
- Erosion can result from extrinsic factors like environmental exposure (acid fumes) and dietary choices (citrus, acidic beverages).
- Intrinsic factors include endogenous acids due to conditions like gastroesophageal reflux, peptic ulcers, and hormonal changes.
- Types of erosive lesions:
- Saucer-shaped concavities primarily on incisors.
- V-shaped notches on premolars and molars, which may lead to pulp exposure.
- Irregularly shaped erosions often on proximal and lingual surfaces due to systemic disorders.
Classification of Erosion
- Extrinsic erosion sources include:
- Environmental factors like acidic fumes.
- Dietary influences from acidic foods and beverages.
- Medications with low pH, increasing risk for dental erosion.
- Intrinsic erosion results from conditions that expose teeth to gastric acids or metabolic/endocrine disorders.
Treatment Modalities
-
Conservative Approaches:
- Surface hardening with stannous fluoride or sodium fluoride paste to reduce sensitivity.
- Remineralization using dentifrices that contain calcium and fluoride.
- Prevention and care for periodontal tissues, including proper oral hygiene techniques.
-
Restorative Approaches:
- Indicated for extensive lesions, utilizing metallic or non-metallic restorations.
- No protective base needed for limited depth lesions; varnish applied to dentin to reduce hypersensitivity.
Abfraction
- Refers to wedge-shaped defects at the cementoenamel junction caused by occlusal forces leading to tooth flexure.
- Stress from masticatory or parafunctional activities targets the CEJ, causing microfractures.
- Restoration may be necessary when clinical consequences, like dentin hypersensitivity, arise, with aesthetic considerations in mind.

Description
This quiz explores the various aspects of tooth wear, including its effects on vitality and sensitivity. It examines how wear is disproportionate in different arches, the inability to achieve proper contact, and the implications for dental treatments. Understanding these features is crucial for effective dental interventions.
