Summary
Scanning electron microscopy (SEM) revolutionized root surface analysis, revealing cementum structure and microbial plaque interactions. This technique enabled unprecedented detail in studying root surface phenomena and calculus formation.
Area of Science:
- Dental Microscopy
- Surface Science
- Periodontology
Background:
- Root surface morphology and cementum structure were historically challenging to study at high resolution.
- Understanding the relationship between root surfaces and overlying microbial communities is crucial for oral health.
Purpose of the Study:
- To review the impact of scanning electron microscopy (SEM) on the understanding of root surface structure and associated phenomena.
- To highlight SEM's contributions to analyzing cementum, microbial plaque, and calculus.
Main Methods:
- Review of studies utilizing scanning electron microscopy (SEM) for root surface analysis.
- Analysis of secondary electron imaging, cathodoluminescence, and backscattered electron imaging techniques.
Main Results:
- SEM provided unprecedented detail on cementum formation, resorption, repair, and fiber mineralization.
- SEM enabled detailed surveys of intact microbial plaque, revealing distinct microenvironments and bacterial interactions.
- SEM elucidated the structure of calculus and its relationship with cementum.
- Advanced SEM techniques detected mineral variations in root surfaces and acquired coatings.
Conclusions:
- Scanning electron microscopy (SEM) has been pivotal in advancing the understanding of root surface biology and pathology.
- SEM continues to offer novel insights into root surface-cementum interactions and oral biofilm structures.
