Root Apex-Anatomical And Physiological Foramen



Apical constriction (Physiological foramen)

  • is conside­­red narrowest diameter of the root canal

  • located at the cement-dentinal junction.

  • it is the apical limit of root canal preparation preparation.

  • it is also known as the histological foramen, because it is located at the junction between the

  • pulpal connective and interstitial loose connective tissues of the periodontal ligament.

  • not visible on x-ray (we may find it only using WL determination methods).
