Primary goal of course
treatment
primary goal of dentist
prevent lesions
tooth prep defined
mechanical aleteration –> form, function, including esthetic corrections
Conventional prep
precise, includes amalgam, ceramic, cast
modified
less precise (simplified) includes composite resins (bonding)
Types of lesions
- Caries 2. Abrasion 3. Erosion 4. Attrition 5. Fracture 6. Developmental Defects 7. Abraction
Caries
infectious disease process, breakdown of enamel and dentin due to bacterial invasion; most common
Abrasion
Pathogenic wearing (abrasive or tooth brushing) of tooth structure-V-shaped defect;gingiva usually healthy
lesion wear gingiva is healthy
abrasion and erosion
Erosion
chemical dissolution of tooth structure-not associated with caries;facial-gingival 1/3; healthy gigiva
Attrition
physiological wear (due to occlusal force)
Fracture
due to trauma
Developmental Defects
restored to remove caries (i.e. peg laterals)
Abraction
Non-carious lesion; combined abrasion and occlusally induced tooth flexure
Episodic caries
demineralization and remineralization
Primary caries
original
Secondary caries
@ jcn of restoration and tooth or under restoration
Residual Caries
Caries that remian post prep
Incipient Caries
Reversible; enamel is intact
Cavitated caries
irreversible, enamel surface is broken
Armamentarium
collection of resources (i.e. equipment)
Basic Elements of Hand Instruments
