The ratio in choosing access flap for surgical endodontics: a review.

In Surgical Endodontics we face complex situations that require the knowlflap and application of both principles of endodontics (cleansing shaping and filling) in the root management, and the principles of surgery (asepsis, non harmfulness and hemostasis) in the phase of access to the root. Among the factors of surgical relevance that for which have been proposed with the largest number of alternatives is the design of access flap. That clearly indicates that not only one flap design can be ideal in all clinical situations. In this article all proposed access flap designs are evaluated in the light of their degree of compliance with ideal requirements in different circumstances. A clear pattern in the decision-making criteria for the selection of access flaps is proposed.
