Dentino-enamel junction

Dentino-cemental junction

Detailed explanation-1: -A basement membrane exists between the enamel organ and dental papilla which will be the site of the future dentin oenamel junction. The dentinoenamel junction is the surface at which the enamel and the dentin of the crown of a tooth are joined.
Detailed explanation-2: -Which of the following embryonic structures becomes the dentinoenamel junction during completion of the tooth development? Basement membrane between the enamel organ and dental papilla.
Detailed explanation-3: -The dentin-enamel junction (DEJ), which is the interfacial region between the dentin and outer enamel coating in teeth, is known for its unique biomechanical properties that provide a crack-arrest barrier for flaws formed in the brittle enamel1.
Detailed explanation-4: -Membrana performativa is the basement membrane, which separates the enamel organ and dental papilla before dentin develops. Future dentinoenamel junction-forms from the boundary present between the inner enamel epithelium and odontoblasts.
Detailed explanation-5: -Dentine formation (Dentinogenesis): Cells from the inner enamel epithelium induce the cells at the periphery of the dental papilla to form dentin forming columnar cells i.e., odontoblasts. Initially, the odontoblasts secrete an unmineralized dentin matrix.
