The epithelial rests of Malassez are remnants of which structure?
Answer: Hertwig's epithelial root sheath
The epithelial rests of Malassez are remnants of Hertwig's epithelial root sheath that persist in the periodontal ligament throughout life.
Which salivary gland produces the most serous secretion?
Answer: Parotid gland
The parotid gland is entirely serous and produces a watery, enzyme-rich (amylase) secretion comprising about 25% of total saliva volume.
Retzius lines in enamel represent:
Answer: Incremental lines of enamel matrix deposition
Striae of Retzius are incremental lines in enamel that represent successive layers of enamel matrix deposited during crown formation.
Which cells produce the principal fibers of the periodontal ligament?
Answer: Fibroblasts
Fibroblasts are the most numerous cells of the periodontal ligament and are responsible for synthesizing and maintaining the collagen fibers.
The neonatal line in primary tooth enamel marks the boundary between:
Answer: Prenatal and postnatal enamel
The neonatal line is a prominent stria of Retzius that marks the junction between prenatally and postnatally formed enamel in primary teeth.
Dead tracts in dentin appear black in transmitted light because they contain:
Answer: Air
Dead tracts are areas where odontoblastic processes have degenerated and the empty dentinal tubules become filled with air, causing them to appear dark in transmitted light.
