Maxillary arch dimensions in Saudi and Egyptian population sample.
American Journal of Orthodontics
|January 1, 1984
Summary
Maxillary arch dimensions differ significantly between Saudi and Egyptian populations, with Egyptians exhibiting larger intercusp distances. This study provides a Middle Eastern reference for anthropological research.
Area of Science:
- Anthropology
- Orthodontics
- Human Biology
Background:
- Maxillary arch dimensions are crucial for understanding craniofacial morphology.
- Previous research has focused on Western and African populations, with limited data from Middle Eastern groups.
Purpose of the Study:
- To compare maxillary arch dimensions between Saudi and Egyptian adults.
- To establish a reference range for Middle Eastern populations.
Main Methods:
- Measurements of canine to canine (C-C), molar to molar (M-M), molar to canine (M-C), and molar to incisor (M-I) distances were taken from 243 subjects.
- Data were analyzed using statistical methods to identify significant differences based on sex and ethnicity.
Main Results:
- Significant sex-based differences were observed in both Saudi and Egyptian samples.
- Egyptians showed significantly larger mean C-C, M-M, and M-I distances compared to Saudis.
- No significant difference was found for the M-C measurement between the groups.
Conclusions:
- The study provides normative data for maxillary arch dimensions in Saudi and Egyptian populations.
- These findings contribute to understanding Middle Eastern craniofacial variation and can inform future anthropological and orthodontic studies.
