Study Notes
Dentine Structure and Composition
- Dentine is the primary component of a tooth, located beneath enamel and surrounding the pulp.
- Dentinogenesis is the formation of dentine, a process involving odontoblasts.
- Odontoblasts are derived from ectomesenchyme cells, which in turn originate from neural crest cells.
- The structure of dentine plays a crucial role in its function, influencing sensitivity, adhesion potential, and resilience to decay and damage.
- Understanding dentine's properties is vital in dental diagnostics, treatment planning, and patient management.
Types of Dentine
- Primary Dentine is formed during tooth development and accounts for the main bulk of the tooth.
- Secondary Dentine is produced after tooth eruption, slowly adding to the dentine throughout life.
- Tertiary Dentine forms as a response to injury or irritation of the pulp, acting as a protective barrier.
Clinical Significance of Dentine
- Knowledge of dentine aids in identifying dental caries, assessing tooth sensitivity, and interpreting radiographic images.
- It guides the choice of restorative materials, bonding techniques, and treatment options.
- Understanding the relationship between dentine and pulp health is critical in managing dental pathologies and facilitating pulp repair.
