Study Notes
Tooth Eruption Definition
- Tooth eruption is a complex process involving the movement of teeth from their developmental position within the jawbone to their functional position in the oral cavity.
Eruptive Phase Begins
- The eruptive phase begins with the formation of the tooth germ.
Tooth Eruption Phases
- Pre-eruptive phase: During this phase, the tooth germ undergoes intraosseous movement within the tooth crypt, before root formation begins.
- Eruptive phase: This phase involves both intraosseous and supraosseous movement of the tooth germ until it enters the oral cavity.
- Post-eruptive phase: This phase begins when the tooth emerges into the oral cavity and concludes when the tooth reaches its fully functional position in the dental arch.
Developmental Processes and Factors
- Epithelial root sheath: This sheath guides the development of the root of the tooth.
- Tooth germ: This is the initial stage of tooth development.
- Dental follicle: This structure surrounds the tooth germ and provides a pathway for the erupting tooth.
After Crown Emergence
- After the crown of the tooth emerges through the alveolar bone, the enamel organ, which forms enamel, degenerates.
Term for Intraosseous and Supraosseous Movement
- The phase of tooth eruption when the tooth germ undergoes intraosseous and supraosseous movement until it enters the oral cavity is known as the eruptive phase.
Factor Contributing to Tooth Movement
- The eruption force contributes to the movement of teeth to maintain their positions of functional occlusion and towards the occlusal plane.
Enamel Organ Degeneration
- The enamel organ degenerates after the crown of the tooth emerges from the alveolar bone.
Phase Before Root Formation
- The pre-eruptive phase occurs before the beginning of root formation and is characterized by the tooth germ moving within the tooth crypt.
Root Elongation Process
- The elongation of the root during tooth eruption is a result of the deposition of dentin and cementum by specialized cells called odontoblasts and cementoblasts.
Enamel Organ Degeneration During the Eruptive Phase
- The enamel organ degenerates and becomes thinner during the eruptive phase.
Root Elongation in the Eruptive Phase
- The deposition of dentin and cementum contributes to the elongation of the tooth root during the eruptive phase.
Process After Intraosseous and Supraosseous Movement
- After the tooth germ undergoes intraosseous and supraosseous movement until it enters the oral cavity, the post-eruptive phase begins.
Maintenance of Occlusion
- The eruption force, generated by epithelial root sheath expansion and dentin deposition at the root apex, contributes to the movement of teeth to maintain their positions of functional occlusion and towards the occlusal plane.
Enamel Organ After Crown Emergence
- After the emergence of the crown of the tooth through the alveolar bone, the enamel organ degenerates and becomes thinner, leaving the enamel surface exposed.
