Resistance of a 4-META–Containing, Methacrylate-based Sealer to Dislocation in Root Canals

摘要: Abstract The dislocation resistance of root fillings created with MetaSEAL, a self-adhesive 4-META–containing methacrylate resin-based sealer, was evaluated. Forty-six incisors were cleaned and shaped using NaOCl EDTA as irrigants. They filled gutta-percha/MetaSEAL or gutta-percha/AH Plus sealer either single-cone technique warm vertical compaction ( n = 10). roots sectioned at the coronal middle thirds to obtain thin slices, which subjected compressive loading displace set sealer/filling toward side slice. remaining six teeth cryofractured for scanning electron microscopic examination. push-out strength AH significantly higher than MetaSEAL irrespective filling techniques (p
