EVALUATION OF CYTOTOXICITY SEALING ABILITY AND CLINICAL ASSESSMENT OF FOUR DIFFERENT ROOT END FILLING MATERIALS

Abstract

When non-surgical attempts

I prove unsuccessful 1 or are I I'

contraindicated, surgical endodontic therapy is needed to save the

tooth.

i ! Several new root-end filling materials have emerged to,! challenge I the preeminence of amalgam as the root-end filling material Qf choice. I i I

The aim of the present study was:

1. To assess clinically and radiographically the effect of amalgam, I Dyract, MTA and Super EBA on healing at three, six1i and twelve I

months..

2. To study the sealing ability of the means of dye penetration technique.
