Summary
The curvature of upper teeth surfaces is greater than lower teeth, with higher vestibular convexity correlating to thicker alveolar bone. These findings offer new insights into tooth anatomy and its impact on oral health.
Area of Science:
- Dental Anatomy
- Periodontology
- Biomaterials Science
Background:
- Tooth surface curvature influences gingival health and the tooth support system.
- Understanding vestibulo-oral planes and alveolar bone thickness is crucial for dental health.
- Existing literature provides a basis for comparative analysis of tooth-bone relationships.
Purpose of the Study:
- To determine the vestibulo-oral planes of permanent upper and lower premolars and molars.
- To measure the thickness of the associated alveolar osseous wall.
- To analyze the relationship between tooth surface curvature and alveolar bone dimensions.
Main Methods:
- Processed 2,727 measurements using statistical procedures.
- Focused on determining vestibulo-oral planes and alveolar bone thickness.
- Comparative analysis between upper and lower teeth, and vestibular vs. oral surfaces.
Main Results:
- Higher degree of curvature observed in vestibular and oral surfaces of upper teeth compared to lower teeth (p > 0.05).
- Vestibular convexities were greater than oral convexities, particularly in the lower third of the crown.
- Increased vestibular curvature correlated with a thicker alveolar osseous wall.
Conclusions:
- The study identified significant differences in tooth curvature and associated bone thickness between upper and lower teeth.
- Findings suggest a stronger vestibular curvature in teeth is linked to thicker alveolar bone, relevant for the studied population.
- Further research with more data points and advanced methods is recommended to explore tooth-bone relationships.
