This fact is from Amelogenesis & Dentinogenesis in Oral Anatomy & Histology. It is a commonly tested concept in NEET MDS examinations. Understanding this fact is crucial for answering MCQs correctly.
Ameloblasts = ectodermal origin = enamel formation
Odontoblasts = neural crest ectomesenchyme = dentin formation
Enamel = most mineralized tissue 96 percent inorganic
Hunter-Schreger bands = enamel prism direction change light dark
Contour lines of Owen = incremental lines dentin
Neonatal line = birth line in enamel and dentin.
