Post and Core in Endodontics

# In restoring an endodontically treated tooth for post core, an absolute minimum of apical fill of gutta percha to be left over to prevent leakage is:
A. 1 mm
B. 2 mm
C. 3 mm
D. 4 mm



The correct answer is D. 4mm

Since there is greater leakage when only 2-3 mm of Gutta-percha is present, 4-5 mm should be retained apically to ensure an adequate seal. Although studies indicate that 4 mm produce an adequate seal, stopping precisely at 4 mm is difficult, and radiographic angulation errors could lead to retention of less than 4 mm. Therefore, 5 mm of gutta-percha should be retained apically.

  1. Alright, here you have discussed about very important topic and I really like it because not everyone can give us good knowledge for dental care perfectly. Again many people suffers from different kind of diseases and when they can feel their dental pain it is just unbearable. And if are finding the best dental clinic then you should visit park avenue dental because from this place you can get all highly experienced dentist.
