Study Notes
Dental Caries and Cavities
- Dental caries is a disease that affects the mineralized tissues of the teeth, leading to decay.
- A cavity represents a permanent defect in tooth structure, resulting in holes or damaged areas.
Tooth Preparation Techniques
- Conventional preparation involves conforming to a specific form for effective restoration.
- Modified preparation allows for less specific methods, especially when bonding techniques are applied, such as with composite materials.
Cavity Preparation Determinants
- Key factors influencing cavity preparation include the size and type of the lesion, choice of restorative material, and the position of the lesion.
Class 2 Carious Lesions
- Class 2 carious lesions involve at least one interproximal surface of a posterior tooth, indicating decay occurring between teeth.
Early Enamel Carious Lesions
- Early enamel interproximal carious lesions typically form just below the contact point between adjacent teeth.
Diagnosis Methods for Interproximal Caries
- Diagnosis can be achieved through various methods such as visual inspection, light transmission tests, electrical resistance measurements, temporary tooth separation, radiographs, and quantitative light-induced fluorescence (QLF).
Radiographic Depth Classification
- E1 indicates caries confined to the outer half of the enamel.
- E2 suggests caries confined to the inner half of the enamel.
- D1 signifies caries that have penetrated 0.5 mm into the dentine.
- D2 indicates caries that extend more than 0.5 mm into the dentine.
