Non carious lesions of teeth and their management.pptx

Description

Non-carious lesions (NCLs) are tooth surface defects not caused by bacteria. They result from physical, chemical, or mechanical processes and commonly affect cervical areas, occlusal surfaces, and incisal edges. The major types are attrition, abrasion, erosion, abfraction, and others like dental fluorosis, hypoplasia, fractures, and craze lines.

1. Attrition

Physiologic or pathologic tooth-to-tooth wear.
Causes: bruxism, parafunction.
Management: control bruxism (night guard), occlusal correction, composite/onlay restorations if sensitivity or aesthetics affected.

2. Abrasion

Mechanical wear caused by external agents.
Causes: hard brushing, abrasive toothpaste, habits (pipe smoking, biting pins).
Management: modify brushing technique, soft brush, desensitizing agents, restore when deep (GIC/composite).

3. Erosion

Chemical dissolution by acids without bacteria.
Causes: citrus drinks, carbonated beverages, GERD, vomiting.
Management: diet counseling, treat GERD, remineralizing agents (fluoride varnish, CPP-ACP), composite/ceramic veneers for severe defects.

4. Abfraction

Micro-fractures at cervical area due to occlusal overload causing flexure.
Management: occlusal adjustment, night guard, restoring V-shaped defects with flowable composite or RMGIC.

5. Others

Dental fluorosis: mild – bleaching; moderate/severe – microabrasion + composite/veneers.

Enamel hypoplasia: remineralization, composite, veneers or crowns.

Craze lines: usually no treatment; polishing, bleaching if esthetic concerns.

Enamel fractures: composite restoration or crown depending on depth.

Tooth wear complexes (combined lesions): multidisciplinary approach with occlusal rehabilitation.
