Scanning electron microscopy in oral mucosal research: a review

Area of Science:

• Oral Biology
• Microscopy Techniques

Background:

• The oral mucosa is a complex tissue with critical roles in protection, sensation, and immune surveillance.
• Understanding its structure and microbial interactions is vital for diagnosing and treating oral diseases.

Purpose of the Study:

• To review the applications and contributions of Scanning Electron Microscopy (SEM) in oral mucosa research.
• To highlight various SEM preparative techniques and their utility in studying oral mucosal structure, microbiology, and pathology.

Main Methods:

• Review of literature focusing on SEM applications in oral mucosa research.
• Discussion of four primary SEM study methods: biopsy/autopsy samples, smears, replica technique, and cell cultures.
• Exploration of structural analysis, including surface morphology and epithelium-connective tissue interactions.

Main Results:

• SEM effectively visualizes oral mucosal surface structures, microbial colonization, and morphology.
• Morphometric analysis using SEM aids in quantifying connective tissue papillae and epithelial cell surface features.
• Computerized image analysis systems enhance SEM research capabilities in oral mucosa studies.

Conclusions:

• SEM is an indispensable tool for comprehensive oral mucosa research, from basic structure to pathological diagnosis.
• Advancements in SEM techniques and analysis systems continue to expand its role in understanding oral health and disease.
