Effect of ultrasonic agitation on marginal adaptation, intratubular penetration and bonding strength of calcium‐silicate‐based endodontic sealers: A laboratory study

Abstract

AbstractThe effect of ultrasonic activation (UA) on marginal adaptation, intratubular penetration and bond strength provided by three calcium silicate‐based sealers was evaluated. Ninety‐six distobuccal root canals of maxillary molars were randomly divided into 8 groups (n = 12) according to the sealer and UA application: EndoSequence BC sealer (ESBC), Sealer Plus BC (SPBC) and Bio‐C Sealer (BCS), using AH Plus (AH) as a control group. The specimens were sectioned at 2, 4 and 6 mm from the apex. The data were statistically analysed using Kruskall–Wallis, Dunn, Mann–Whitney and chi‐squared tests. UA improved the marginal adaptation of ESBC (6 mm), SPBC (all levels), BCS (2/4 mm) and AH (4 mm) (p < 0.05); the bond strength of SBPC (2 mm) and BCS (6 mm) were also improved (p < 0.05). The UA of endodontic silicate‐based sealers improved the marginal adaptation in all levels and the bond strength of SBPC and BCS sealer.
