Bolton tooth size ratio among Sudanese Population sample: A preliminary study

Area of Science:

• Dental Morphology
• Anthropology
• Forensic Dentistry

Background:

• Mesiodistal tooth size and dental arch morphology are crucial in clinical dentistry, forensic science, and anthropology.
• Understanding tooth-size ratios aids in various dental applications.

Purpose of the Study:

• To determine tooth-size ratios in a Sudanese sample with Class I normal occlusion.
• To compare these ratios with Bolton's study findings and between genders.

Main Methods:

• Utilized dental casts from 60 Sudanese subjects (30 males, 30 females).
• Applied the Bolton formula for overall and anterior tooth-size ratio calculations.
• Employed statistical analysis, including correlation coefficients and Student's t-test, for comparisons.

Main Results:

• Overall and anterior tooth-size ratios were comparable to Bolton's Caucasian sample.
• No statistically significant differences were found in tooth-size ratios between males and females.
• A strong positive correlation (r = 0.79) was observed between anterior and overall ratios.

Conclusions:

• The findings suggest similarities to Caucasian tooth-size ratios but require cautious interpretation.
• The diverse racial composition of the Sudanese population complicates definitive conclusions.
• A larger, more geographically representative study is recommended for the Sudanese population.
