Understanding Key Dental Structures: From Membrana Performatica to Gingival Fibers

Question 1. Membranaperformatica
Answer:

• It separates the enamel organ and dental papilla before the dentin formation
• It determines the morphology of the crown.

Question 2. Hemidesmosomes
Answer:

• Hemidesmosomes attach the cells to the basal lamina
• The lamina propria below the junctional epithelium keeps the epithelial cells of the junctional epithelium immature so that they can develop hemidesmosomes and attach to the tooth
• They then migrate with their attachment being maintained by hemidesmosomes

Function:

• Hemidesmosomes hold the cells to the basal lamina by this, the strength of the attachment is maintained despite migration

Question 3. Gingival group of fibers
Answer:
