Summary
This study measured maxillary anterior tooth dimensions in adults. Tooth size varied by race and gender, but tooth dimension ratios remained consistent, not aligning with the golden proportion.
Area of Science:
- Dentistry
- Dental Anatomy
- Anthropometry
Background:
- Accurate tooth dimensions are crucial for dental restorations and esthetics.
- Understanding variations in tooth size and proportion is important for personalized dental treatments.
Purpose of the Study:
- To determine the average dimensions of the six maxillary anterior teeth in a specific population.
- To evaluate the relationships between intertooth and intratooth dimensions.
- To assess the correlation between tooth dimensions and the golden proportion.
Main Methods:
- Dental casts were created from 54 patients aged 18-35.
- Digital calipers were used to measure tooth length and width on the casts.
- Length-to-width, width-to-width, and length-to-length ratios were calculated.
Main Results:
- Tooth dimensions showed some variation based on race and gender.
- Intertooth and intratooth dimension ratios were found to be consistent across the population.
- The golden proportion did not correlate with any of the calculated tooth dimension ratios.
Conclusions:
- Maxillary anterior tooth dimensions exhibit population-specific variations.
- Consistent tooth dimension ratios suggest a standardized underlying anatomical structure.
- The golden proportion is not a reliable predictor of natural maxillary anterior tooth proportions.
