Scanning electron microscopic study of odontogenic keratocysts

Area of Science:

• Oral pathology
• Scanning electron microscopy
• Cellular biology

Background:

• Odontogenic keratocysts are common developmental cysts of the jaw.
• Understanding their cellular structure is crucial for diagnosis and treatment.
• Previous studies have utilized various microscopic techniques.

Purpose of the Study:

• To investigate the surface cell morphology of odontogenic keratocysts using scanning electron microscopy (SEM).
• To examine the characteristics of surface cells, prickle cells, basal cells, and the epithelial-connective tissue interface.

Main Methods:

• Three odontogenic keratocysts were analyzed.
• Scanning electron microscopy (SEM) was employed to examine cellular structures.
• Detailed observation of surface cells, prickle cells, basal cells, and the epithelial-connective tissue interface was performed.

Main Results:

• Surface cells exhibited short, discontinuous, branched, or beaded microridges.
• Flattened keratinized cells formed intracellular networks of delicate microfilaments.
• Prickle cells displayed numerous cytoplasmic projections and large, round nuclei.
• Basal cells showed two types of cytoplasmic processes and large, oval, polarized nuclei.
• A fibrous and fibrillar network connected the epithelium and lamina propria.

Conclusions:

• SEM provides detailed insights into the surface ultrastructure of odontogenic keratocysts.
• The observed cellular features contribute to understanding the biological behavior of these cysts.
• Further research can build upon these morphological findings for clinical applications.
