“…The cohesive failures of adhesive materials are related to the high values of bond strength, predicting an effective bonding. 46 It is also suggested that the number of cohesive failures of adhesives indicate a normal distribution of stresses during the mechanical testing of bond strength. 47 Resin-dentin interface analysis for the etch&rinse adhesive system revealed a thick, well-defined hybrid layer.…”

Nano glass ionomer exhibited significantly lower shear bond strength compared to nano-composites. The self-etch adhesive showed higher shear bond strength than etch&rinse adhesive for both nanofill and flowable nanofill composites. Materials and Methods: Sixty human molars were ground flat, exposing the dentin surfaces, and they were randomly divided into five groups according to the restorative materials and adhesive systems used (n=12/group). The restoratives were applied to all dentin surfaces according to the manufacturer's instructions, using a special jig (Ultradent) in the following manner: Group 1: a nano-composite (NC) (Filtek Supreme XT-3M ESPE) was applied with a two-step self-etch adhesive (SE) (Adper SE Plus-3M ESPE); Group 2: NC was applied with an etch&rinse adhesive (SB) (Adper Single Bond 2-3M ESPE); Group 3: a flowable nano-composite (FNC, Filtek Supreme XT Flow-3M ESPE) was applied with SE; Group 4: FNC was applied with SB and Group 5: a nanofilled resin-modified glass ionomer (Ketac N100-3M ESPE) was applied with Ketac Nano Primer (3M ESPE). The bonded specimens were stored in distilled water (37°C, 24 hours) and tested for SBS in a universal testing machine (1 mm/minute). Two specimens from each group were subjected to SEM evaluations of the adhesive interfaces. Failure modes were determined using a stereomicroscope. The mean SBS values were calculated and the data were analyzed with the Kruskal Wallis and Mann-Whitney-U tests (p<0.05). Results: Mean SBS values (MPa) for the groups were 13.64; 7.83; 11.20; 4.12 and 0.64 for Groups 1, 2, 3, 4 and 5, respectively. Group 1 exhibited a significantly higher value than all the other groups; whereas, Group 5 had the lowest value (p<0.05). The SE adhesive yielded higher bond values than the SB adhesive with NC

“…Human freshly extracted mandibular premolars with approximately similar apical diameters (# #20) and similar root length (16±1 mm) and rounded canal cross section were selected. The teeth were collected in jar filled with 10% formalin that storage of teeth by freezing, or in media such as neutral buffered formalin, chloramine, and distilled water, did not significantly affect the shear bond strength of the resin to dentin (17) .…”

Dentin Bond Strength Evaluation of Three Root Canal Sealers with Cold Gutta-Percha Lateral Obturation Technique: Push-Out Test Study

2017

Aim: This study was designed to evaluate dentin bond strength by push-out test of three root canal sealers (IRoot SP, AH Plus, and MTA Fillapex endodontic sealers) with cold gutta-percha lateral obturation technique using push-out test. Methods: A total of 57 human freshly extracted mandibular premolar teeth for orthodontic reason were used in this study. All samples were decoronated 16±1mm from the apex and prepared using step-back technique up to master apical file # 40. The specimens were divided randomly into three groups (19 teeth each) according to the type of sealers used; Group 1(IRoot SP), Group 2(AH Plus sealer), and Group 3 (MTA Fillapex sealer). Each group was obturated with cold gutta-percha lateral obturation technique. The specimens were incubated for 7 days at 37 o C with 100% humidity. Three sections of 2 mm thickness were obtained at 3, 7 and 11mm from the apex to represent apical, middle and coronal third respectively. The push-out bond strength was determined for each root slice. Values were recorded, tabulated for each group and statistically analyzed. Results: IRoot SP showed the highest mean value of push-out bond strength (7.3±0.2), followed by AH Plus (6.8±0.1) while MTA Fillapex showed the lowest mean value of push-out bond strength (2.9±0.3). Conclusions: IRoot SP and AH plus sealers had greater resistance to push-out than MTA Fillapex sealer.
