Study Notes
Factors Affecting Laser Effects
- The effect of laser depends on the power of the beam and the extent to which it is absorbed.
- When using laser for cutting enamel and dentin, it generates heat, which may affect the pulp, so it should be used in a pulsating manner to avoid continuous heat generation.
progression of Lesions
- Lesions progressing rapidly when occurring at the cement-enamel junction (CEJ) due to thin enamel and mechanical forces that wear away dentin and cementum quickly.
Effect of Periodontal Disease on Pulp
- The accumulative effect of periodontal disease has a damaging effect on the pulp, indicated by pulp calcification, inflammation, or resorption.
- Total pulp disintegration is certain only when the apical foramen is infected.
Factors Contributing to Intratubular Occlusion
- The above-mentioned factors contribute to intratubular occlusion, reducing permeability.
Dead Tracts
- Dead tracts are regions of empty tubules in primary dentin resulting from degeneration of the odontoblastic process.
- They are often found under most carious cavities.
