Dark bonds that are present in enamel rods at intervals of 4 μms are______________?
Correct answer: B. Cross striations
- A. Neonantal bands
- B. Cross striations
- C. Striae of Retzius
- D. Hunter-Schregar bands
Explanation
Cross striations are transverse markings across enamel rods, usually appearing at about 4 μm intervals and representing the daily rhythm of enamel deposition. Striae of Retzius are longer-period incremental lines, while Hunter-Schreger bands are alternating groups of rods seen in longitudinal sections.
