Study Notes
Caries Balance Concept
- Caries is not caused by a single factor.
- Caries develops due to the complex interplay of factors that promote or protect against tooth decay.
- Poor oral hygiene, frequent consumption of cariogenic snacks and sugary drinks between meals, and hyposalivation contribute to caries development.
Chronic Dental Caries
- Chronic caries progress slowly towards the pulp.
- Chronic caries appears dark and hard.
- The thickness of chronic caries is greater on cuspal heights and incisal edges compared to the cervical areas of the tooth.
- The hardness of chronic caries is softer than enamel.
- The modulus of elasticity for dentin is low, indicating its flexibility.
- Dentin's flexibility provides support and cushions the enamel, preventing fracture.
- The radius and number of dentinal tubules increase towards the pulp.
- There are approximately 45,000 dentinal tubules with larger diameters found closer to the pulp.
- Near the dentin-enamel junction (DEJ), there are approximately 20,000 tubules with smaller diameters.
