Relationship between torus mandibularis and number of present teeth
Scandinavian Journal of Dental Research
|June 1, 1986
Summary
Torus mandibularis, a bony growth, is positively associated with having more teeth. This oral health trait appears linked to jaw development and may be maintained by the presence of functioning teeth.
Area of Science:
- Oral biology
- Dental anthropology
- Human anatomy
Background:
- Torus mandibularis is a common bony exostosis.
- Its relationship with dental status is not fully understood.
Purpose of the Study:
- To investigate the association between torus mandibularis and the number of present teeth.
- To explore potential links with jaw development and age-related changes.
Main Methods:
- Retrospective analysis of 2010 dental patients over 10 years of age.
- Comparison of torus mandibularis incidence and average teeth count.
- Statistical analysis across different age groups.
Main Results:
- A significant positive correlation was found between torus mandibularis and the number of present teeth (P < 0.0000001).
- Adolescents with torus mandibularis had fewer unerupted canines, suggesting better jaw development.
- Torus mandibularis incidence decreased with age, mirroring the decline in present teeth.
Conclusions:
- Torus mandibularis is significantly associated with a higher number of present teeth.
- The trait may indicate more adequately developed jaws, particularly in adolescents.
- The presence of functioning teeth appears important for maintaining torus mandibularis.
