Summary
Understanding dental eruption sequences is key for harmonious occlusion. This study determined average eruption ages for permanent canines, premolars, and molars in 574 children, analyzing sex-based differences.
Area of Science:
- Dentistry
- Pediatric Dentistry
- Orthodontics
Background:
- Harmonious occlusion development depends on correct dental eruption sequences.
- Previous research has explored occlusion through successive phases of dental eruption.
Purpose of the Study:
- To investigate the eruption rhythm of permanent teeth.
- To determine the average eruption age for specific permanent teeth (canines, premolars, second molars).
- To analyze eruption timing based on sex.
Main Methods:
- Analysis of dental eruption patterns in a sample of 574 children.
- Determination of average eruption ages for canines, first and second premolars, and second molars.
- Sex-specific data collection and analysis.
Main Results:
- Established average eruption ages for permanent canines, first premolars, second premolars, and second molars.
- Presented eruption data for 574 children.
- Highlighted potential sex-based variations in eruption timing.
Conclusions:
- The study provides normative data on permanent tooth eruption timing.
- Understanding these eruption sequences is crucial for pediatric dental care and orthodontic planning.
- Sex may influence the eruption timeline of certain permanent teeth.
