Summary
Electron microscopy revealed both intracellular and extracellular calcification in supragingival calculus from periodontitis patients. This calcification process occurs within microorganisms and the interbacterial matrix.
Area of Science:
- Microbiology
- Biomineralization
- Periodontology
Context:
- Supragingival calculus is a common finding in patients with periodontitis.
- Understanding calculus formation is crucial for effective periodontal disease management.
Purpose:
- To investigate the ultrastructural characteristics of calcification within old supragingival calculus.
- To elucidate the sites and initial mechanisms of calculus biomineralization.
Summary:
- Electron microscopy was used to examine supragingival calculus specimens from five periodontitis patients.
- Both intracellular calcification, starting as crystals or deposits within microorganisms, and extracellular calcification, originating in the interbacterial matrix, were observed.
Impact:
- Provides detailed insights into the micro-mechanisms of supragingival calculus formation.
- Contributes to the understanding of biomineralization processes in oral biofilms.
- Informs potential strategies for preventing or treating calculus accumulation in periodontal disease.
