Shear Bond Strength of 2 Root Canal Sealers to Human Dentin
ثبت نشده
چکیده
The purpose of the present study was to compare the shear bond strength to human dentin of 2 root canal sealers: Sultan U/P (zinc-oxide euge nol) and 2seal (epoxy resin). The dentin specimens were divided randomly into 2 groups (A, B) of 12 specimens each, and etched with 3 ml of EDTA 17% before rinsing with NaOCl 2.5% and distilled water. The 2 sealers were mixed according to the manufacturer instructions and placed on dentin surfaces. Bond strength was tested using a universal test machine at a cross-head speed of 0.5 mm/min. Data were analyzed with Student t-test. The results indicated that 2seal presented statistically significant higher values of bond strength than Sultan U/P.

BACKGROUND One of the essential properties of the root canal sealers is the adhesion to root canal dentin and their higher bond strength decreases the microleakage. The aim of the present study was to compare the effect of Different Intracanal medicaments on the push out bond strength of AH26 and MTA Fillapex sealers. MATERIAL AND METHODS A total of 104 one-rooted extracted human teeth were d...

OBJECTIVE The aim of this in vitro study was to evaluate the bond strength of different root canal sealers to dentin. MATERIAL AND METHODS Forty extracted single-rooted human teeth were examined and the coronal and middle thirds of the canals were prepared with a 1.50 mm post drill (FibreKor Post System, Pentron). The teeth were allocated in two experimental groups, irrigated with 2.5% NaOCl+...
متن کاملShear bond strength of epoxy resin-based endodontic sealers to bovine dentin after ozone application.
The idea of using ozone to disinfect root canals is of recent origin. The wide acceptance of epoxy resin-based sealers lead us to investigate whether ozone can influence the adhesion to the dentin. In this study, we tested the shear bond strength of AH Plus and EZ Fill. Forty freshly extracted bovine teeth were randomly divided into 5 groups. 16 of these samples were treated with ozone for 60 s...
