A comparative study between three ethnic groups to derive some standards for maxillary arch dimensions

Area of Science:

• Anthropology
• Orthodontics
• Dental Morphology

Background:

• Maxillary arch dimensions are crucial for dental alignment and facial aesthetics.
• Understanding population-specific variations in maxillary arch dimensions is important for orthodontic diagnosis and treatment planning.
• Previous studies have documented maxillary arch dimensions in various ethnic groups, but data for adult Filipinos is limited.

Purpose of the Study:

• To measure key maxillary arch dimensions in a sample of adult Filipinos.
• To compare these measurements with published data from adult Egyptians and Saudi Arabians.
• To identify potential ethnic variations in maxillary arch morphology.

Main Methods:

• A sample of 91 adult Filipinos (45 males, 46 females) was selected.
• Maxillary arch measurements included intercanine width (C-C), intermolar width (M-M), molar incisor (M-I), and molar canine (M-C) length.
• Measurements were statistically compared to existing data from Egyptian and Saudi Arabian populations.

Main Results:

• Filipinos exhibited wider intercanine width (C-C) compared to Saudi Arabians.
• Egyptians showed wider intermolar width (M-M) measurements than Filipinos.
• No significant differences were noted for molar incisor (M-I) and molar canine (M-C) lengths between the groups.

Conclusions:

• Significant differences exist in maxillary arch dimensions among Filipino, Egyptian, and Saudi Arabian adult populations.
• These findings highlight the importance of considering ethnic variations in orthodontic treatment.
• Further research is recommended to explore the genetic and environmental factors influencing these dimensional differences.
