“…However, consensus on the appropriate thickness for push-out testing is lacking. Dentin slices with 2-mm thicknesses were used to examine push-out bond strength in the present study and in previous studies, 8,17 but 1-mm-thick slices have been used in other studies. 28,29 Carbonated apatite, also known as biological apatite, represents the mineral phase of hard tissues (bone, dentin, and cementum).…”

“…32 However, the specimens were not stored for a long period before coronal restoration in the regenerative endodontic procedure to simulate clinical conditions. As mixing technique has been shown to have an insignificant effect on push-out bond strength of white MTA, 17 conventional mixing was employed for all samples in this study. Some studies have evaluated the effect of condensation technique on the bond strength of MTA to root dentin.…”

“…The Vibringe system (Cavex Holland BV, Haarlem, The Netherlands), which uses sonic flow technology combined with acoustic streaming, has a cordless handpiece that delivers irrigant continuously and in a pulsatile manner directly into the root canal via a standard needle. 16 In vitro studies have investigated the effects of mixing technique, 17 mixing solution, 18 technique of MTA condensation into the cavity, 19 irrigation solution used in the root canal, 9 and acidic environment 10 on the push-out bond strength of MTA to dentin. The question is whether the use of TAP for regeneration procedures decreases the bond strength of MTA to dentin after irrigation, due to its acidity.…”

This study evaluated the bond strength of mineral trioxide aggregate (MTA) to root canal dentin after the performance of various irrigation procedures to remove triple antibiotic paste (TAP). A total of 56 single-rooted human mandibular premolars were instrumented using a rotary system to size 40 and divided randomly into a control group (no intracanal dressing) and three experimental groups (TAP application for 28 days). TAP was then removed by rinsing with 10 mL 2.5% NaOCl using three irrigation systems (Vibringe sonic irrigation, CanalBrush, and syringe irrigation). The coronal and middle parts of root canals were then obturated with MTA. After storage for 1 week, each specimen was embedded in an acrylic block and sectioned horizontally (2-mm-thick slices) at two levels (coronal and middle). Bond strength of MTA to root canal dentin was assessed in 28 samples per group via push-out test using a universal testing machine. Data from the four groups were compared using one-way analysis of variance. Tukey's test was used for multiple comparisons. Push-out bond strength values were significantly higher in the control and Vibringe groups than in the CanalBrush and syringe irrigation groups (p < 0.001). TAP removal from root canals with the Vibringe irrigation system may increase the push-out bond strength of MTA compared with the use of the CanalBrush or syringe irrigation.

“…An ideal root-end filling material has to be biocompatible, dimensionally stable, adhere to the dentinal walls with excellent marginal adaptation preventing the passage of bacteria, and be unaffected in the presence of tissue fluids that may be acidic in an infected area. [1][2][3][4] Mineral trioxide aggregate (MTA) has most of these essential properties and is highly popular as a root-end filling material. 5 Recently a new tricalcium silicate-based material has been introduced, known as Biodentine, the applications of which are similar to those of MTA.…”
