What is mouse hole effect in endodontics?
Extension of orifices to the axial walls results in “mouse hole effect” (Figs 15.33A and B). It is caused because of under extension of the access cavity. It results in hindrance to the straight line access which may further cause procedural errors.
What is Endo Z bur used for?
Endo Z Bur: The Endo Z bur is a tapered and safe-ended carbide bur (Figure 6d).
