HIGHLIGHTSPOBT in endodontic research predicts the clinical behavior of endodontic material s .
Introduction : There is limited literature on the impact of testing variables on the push‐out bond test ( POBT ) .
This review identified design s of the POBT used in the endodontic literature and aim ed to determine which experimental variables may influence the push‐out bond strength ( POBS ) .
Effect of photo-activated disinfection on bond strength of three different root canal sealers
Introduction : The aim of this in vitro study was to evaluate the bond strength of Photo-Activated Disinfection ( PAD ) system to dentin with different root canal sealers by using a push-out test design . Material s and Methods : A total of 30 extracted m and ibular premolar teeth with single and straight roots were used . The crowns were removed and the root canals were prepared by using ProTaper rotary files . The smear layer was removed and the roots were r and omly divided into two groups ( n = 15 ) according to the use of PAD system as the final disinfecting agent . Each group was then divided into 6 ( n = 5 ) subgroups and obturated with gutta-percha and 3 different root canal sealers . The groups were Group 1 : Sodium hypochlorite ( NaOCl ) + ethylenediaminetetraacetic acid (EDTA)-AH Plus sealer ; Group 2 : NaOCl + EDTA + PAD-AH Plus ; Group 3 : NaOCl + EDTA-Sealapex ; Group 4 : NaOCl + EDTA + PAD-Sealapex ; Group 5 : NaOCl + EDTA-mineral trioxide aggregate (MTA)-Fiallapex ; and Group 6 : NaOCl + EDTA + PAD-MTA-Fillapex . 1-mm thickness horizontal sections ( n : 5 × 4 = 20 ) were sliced for the push-out bond strength measurement . Results : Group 3 and 4 showed significantly lower bond strengths compared with all the other groups ( P < 0.05 ) . No statistically significant difference was found among Groups 1 , 2 and 5 , but there was statistically significant difference between Group 5 and 6 ( P < 0.05 ) . Conclusion : This in vitro study indicated that the PAD system adversely affected the bond strength of the MTA Fillapex root canal sealer
