Dentinoenamel Junction


  • DEJ appears as a scalloped line.
  • The convexities of scallop are directed towards the dentine 
  • The surface of dentine appears pitted
  • DEJ provides strength to the union between enamel and dentin
Clinical Significance:
  • Prevents shearing of enamel when functioning.
  • Scalloping of the junction is seen more in the occlusal portion where masticatory stresses are high.
