Summary
Tooth eruption is a complex process with distinct phases, influenced by systemic and local factors. Understanding these stages is crucial for accurate assumptions about dental development across all age groups.
Area of Science:
- Dentistry
- Developmental Biology
- Orthodontics
Background:
- Tooth eruption assumptions based on adolescents may not apply universally.
- The eruptive process involves distinct profunctional and postfunctional stages.
Purpose of the Study:
- To present a theoretical explanation for eruption control across different developmental stages.
- To incorporate recent research into working hypotheses on tooth eruption.
Main Methods:
- Review and synthesis of existing research on tooth eruption.
- Development of a phased model for tooth eruption.
- Formulation of working hypotheses based on current scientific understanding.
Main Results:
- Tooth eruption is divided into six phases: three profunctional and three postfunctional.
- Pre-emergent eruption is rate-limited by independent resorptive processes.
- Post-emergent eruption is influenced by occlusal loading and tongue pressure, with cellular adaptation in adults.
Conclusions:
- Tooth eruption dynamics vary significantly across different developmental stages.
- Systemic and local factors differentially impact eruption rates.
- Cellular adaptation of alveolar bone and gingiva is key to adult eruption control.
