Now a days..the scenario of surgical endodontics has drastically
changed due to use of dental operating microscope and newer and better materials..
With the use of microsurgical instuments, ultrasonics and magnification, the
bone removal is minimum, retrograde cavity prepartion is better and thus
the prognosis is also improved.
Many case reports have been published in favour of MTA as retrograde filling material.
I have also used it in 4 cases and results are really satisfactory..
