Variation in size and form between left and right maxillary central incisor teeth
The Journal of Prosthetic Dentistry
|March 1, 1980
Summary
Most individuals exhibit significant differences in the size and shape of their left and right maxillary central incisors. This asymmetry is common, affecting over 86% of subjects studied.
Area of Science:
- Dentistry
- Human Anatomy
- Dental Morphology
Background:
- The maxillary central incisors are crucial for facial aesthetics and function.
- Understanding the symmetry of these teeth is important for orthodontic and restorative treatments.
Purpose of the Study:
- To quantify the degree of dimensional and morphological asymmetry between left and right maxillary central incisors in a study population.
- To determine the prevalence of substantial differences in maxillary central incisor form.
Main Methods:
- Collated results from examinations of subjects' maxillary central incisors.
- Evaluation of dental dimensions and morphology for symmetry.
Main Results:
- 86% to 90% of subjects displayed asymmetry in left and right maxillary central incisor dimensions or form.
- Over 60% of these subjects presented substantial differences, indicating significant asymmetry.
Conclusions:
- Asymmetry in maxillary central incisor dimensions and morphology is highly prevalent.
- Significant asymmetry is common, impacting over half of the studied population.
