Mantle dentine in man--a quantitative microradiographic study
Journal De Biologie Buccale
|June 1, 1986
Summary
This study reveals that mantle dentine, located at the amelodentinal junction, has a significantly lower mineral density than circumpulpal dentine. This finding highlights variations in tooth structure mineral content.
Area of Science:
- Dental Anatomy
- Mineralogy
- Biomaterials
Background:
- Dentine exhibits regional variations in mineral density.
- The amelodentinal junction (ADJ) is a critical interface in tooth structure.
Purpose of the Study:
- To quantitatively assess and compare the mineral density of circumpulpal dentine and mantle dentine.
- To investigate the structural characteristics of the ADJ using densitometry and polarized light microscopy.
Main Methods:
- Microradiography and densitometric analysis of 50 human tooth sections (aged 18-56).
- Quantitative analysis using graphic and electronic computer methods.
- Examination of sections using polarized light microscopy.
Main Results:
- Mantle dentine, a peripheral zone averaging 150 microns, showed a lower mineral density (approx. 42% volume) compared to circumpulpal dentine (approx. 46% volume).
- The 4% difference in mineral density between these regions was statistically significant.
- Polarized light microscopy confirmed the presence of peripheral mantle dentine.
Conclusions:
- Mantle dentine is demonstrably less mineralized than circumpulpal dentine.
- The findings underscore the structural heterogeneity of dentine and highlight the ADJ as an area requiring further research.
