AB  - The adhesion of fiber posts luted with simplified adhesive systems has been a matter of great interest over the past years. The aim of this study was to assess the post retentive potential of experimental self-adhesive resin cement (EXP) when used alone and in combination with a self-etch adhesive. Fiber posts were placed in endodontically treated teeth and divided into four groups (n = 6) according the luting material, as follows: group 1 (EXP alone); group 2 (EXP used with self-etch adhesive); group 3 (marketed dual-cured cement used with self-etch adhesive); and group 4 (marketed self-adhesive cement). The push-out test was used to assess the retentive strength of fiber posts (expressed in MPa), and specimens were analyzed under a stereomicroscope to determine failure mode. The adhesive interface between the cement and root canal dentin for each group was evaluated using scanning electron microscopy. The post retentive potential of group 1 (EXP) (7.48 +/- 4.35 MPa) was comparable with that of marketed cements from group 4 (6.79 +/- 3.68 MPa) and group 3 (8.77 +/- 4.58 MPa). When EXP was used in combination with self-etch adhesive (group 2), significantly higher push-out bond-strength values were measured (15.87 +/- 4.68 MPa) compared with the other groups.

AB  - Purpose: To assess the shear bond strength to unground human enamel (ESBS) and flexural strength (FS) of different reinforcing fibers used in combination with a flowable composite resin. Materials and Methods: For ESBS testing, 90 human molars were selected and randomly divided into 9 groups (n = 10) according to the reinforcing fiber to be tested: 1. RTD Quartz Splint additionally impregnated at chair-side with Quartz Splint Resin (RTD); 2. RTD Quartz Splint without additional impregnation; 3. Ribbond- THM (Ribbond) impregnated with OptiBond FL Adhesive; 4: Ribbond Triaxial (Ribbond) impregnated with OptiBond FL Adhesive; 5. Connect (Kerr) impregnated with OptiBond FL Adhesive; 6. Construct (Kerr) impregnated with OptiBond FL Adhesive; 7. everStick PERIO (Stick Tech); 8. everStick C&B (Stick Tech); 9. nonreinforced composite Premise flowable (Kerr). Cylinders of flowable composite reinforced with the fibers were bonded to the intact buccal surface of the teeth. After 24 h of storage, shear loading was performed until failure occurred. FS was assessed performing three- point bending test according to ISO Standard 4049/2000. ESBS and FS data were analyzed using one- way ANOVA, followed by Tukey's HSD test for post- hoc comparisons (p  lt  0.05). Results: For each group, the ESBS and FS, respectively, in MPa were: 1. 17.07 +/- 4.52 and 472.69 +/- 30.49; 2. 14.98 +/- 3.92 and 441.77 +/- 61.43; 3. 18.59 +/- 5.67 and 186.89 +/- 43.89; 4. 16.74 +/- 6.27 and 314.41 +/- 148.52; 5. 14.38 +/- 4.14 and 223.80 +/- 77.35; 6. 16.00 +/- 5.55 and 287.62 +/- 85.91; 7. 16.42 +/- 3.67 and 285.35 +/- 39.68; 8. 23.24 +/- 5.81 and 370.46 +/- 29.26; 9. 12.58 +/- 4.76 and 87.75 +/- 22.87. For most fibers, no significant difference in ESBS was found compared to the control group, except for everStick C&B, which yielded higher ESBS. Nonreinforced composite exhibited the lowest FS, while all fibers positively affected the FS. Conclusions: Fiber reinforcement of flowable composite does not affect its ESBS. The flexural strength of FRCs is significantly influenced by fiber composition and pattern.

AB  - Purpose: To evaluate the influence of different surface treatments and metal primer application on bond strength of zirconia ceramic to a self-adhesive resin cement. Methods: 40 cylinder-shaped (empty set 12 x 5.25 mm high) of zirconia ceramic (Aadva Zirconia) were randomly divided into four groups (n= 10), based on the surface treatment to be performed: (1) Sandblasting with 125 mu m Al2O3 particles (S) (positive control); (2) Selective infiltration etching (SIE); (3) Experimental heated etching solution applied for 30 minutes (ST); (4) No treatment (C). Half of the zirconia specimens of each group received the application of Metal Primer II. Eight disks for each group were luted using a self-adhesive resin cement (G-Cem Automix) to composite overlays (Paradigm MZ100). After 24-hour storage (37 degrees C, 100% RH) bonded specimens were cut into microtensile sticks and loaded in tension until failure. Data were analyzed with two-way ANOVA and Games-Howell (P lt  0.05). Failure mode distribution was recorded and scanning electron microscopy (SEM) was used to examine the fractured microbars. The remaining cylinders of each group (n= 2) were used for SEM surface analysis. Results: Both surface treatments and Metal Primer IT application improved bond strength values (P lt  0.05). When Metal Primer II was not applied ST treatment achieved highest bond strength values (22.17 +/- 10.37 MPa). Sandblasting in combination with Metal Primer II enhanced bond strength values compared to the other groups (23.46 +/- 11.19 MPa). (Am J Dent 2012;25;269-275).

AB  - Purpose: To evaluate the effect of different intermediate resin agents on composite-to-composite microtensile bond strength (mu TBS). Methods: Composite disks (8 x 4 mm) of Gradia Direct Anterior (N= 15) and Filtek Supreme XT (N=15), stored in a saline solution at 37 degrees C for I month, were sandblasted (Microetcher, 50 mu m-Al2O3), cleaned (35% H3PO4), and randomly divided into five groups (N=3) according to the intermediate agent applied. Two flowable composites (Gradia LoFlo; Filtek Supreme XT Flow) and two adhesives (Adper Scotchbond 1XT, Scotchbond Multi-Purpose) were used. As a control, no intermediate agent was applied., Each disk was incrementally repaired (W mm) with the same resin as the respective substrate. By serially cutting each repaired specimen, multiple sticks of about 0.8 mm(2) in cross-section were obtained and loaded in tension until failure at a cross-head speed of 0.5 mm/minute. Data were statistically analyzed. Failure mode was examined by stereo- and scanning electron-microscopy (SEM). Additional specimens were prepared to morphologically evaluate the composite-to-composite interfacial quality by SEM analysis. Results: Composite substrate and intermediate agent were significant factors (Two-way ANOVA, P lt  0.001). Bond strengths achieved with Gradia Direct Anterior were higher than Hick Supreme XT. The application of flowable composites resulted in statistically superior mu TBS than adhesives and control (Tukey test, P lt  0.001). Failure mode was predominantly cohesive (flowable composites), cohesive/adhesive (adhesives) and adhesive (no treatment). Flowable composites and adhesives showed a good interfacial quality.

AB  - The aim of this study was to investigate the adhesion of fiber posts cemented with luting agents that utilize three currently available adhesive approaches: etch-and-rinse, self-etch, and self-adhesive. Forty-two intact single-rooted human premolars were used in the study. Teeth were divided into six groups. In each group, a different resin cement with its adhesive system (if needed) and a fiber post were used. The groups were classified, according to the adhesive approach, into the following three categories. (i) Etch-and-rinse groups: Calibra resin cement/XPBond adhesive + self-curing activator (SCA)/RadiX Fiber Post (Dentsply Caulk), FluoroCore 2 core build-up material/XPBond + SCA/RadiX Fiber Post (Dentsply Caulk), and MultiCore Flow luting and core build-up material/Excite DSC adhesive/FRC Postec Plus fiber post (Ivoclar Vivadent). (ii) Self-etch group: Panavia F 2.0/ED primer (Kuraray)/RadiX Fiber Post (Dentsply Caulk). (iii) Self-adhesive groups: experimental self-adhesive cement/RadiX Fiber Post (Dentsply Caulk), and RelyX Unicem/RelyX Fiber Post (3M ESPE). The adhesion between the post and the root canal walls was assessed using the 'thin-slice' push-out test. In the test arrangement used, the self-etching approach may offer less favourable adhesion to root canal dentin in comparison with etch-and-rinse and self-adhesive approaches.

AB  - This study examined the influence of different surface conditioning methods on composite-to-composite microtensile bond strength. Thirty two-year old composite resin discs were randomly divided into three groups according to the different mechanical/chemical surface pretreatment tested: (1) 38% hydrogen peroxide (H2O2) -treatment; (2) 50-mu m aluminum oxide sandblasting; (3) no treatment. Depending on the intermediate agent applied, two subgroups were created: (A) three-step adhesive system; (B) prehydrolyzed silane coupling agent + three-step adhesive system. Microtensile bond strength measurements were performed and the data were statistically analyzed with Kruskall-Wallis Analysis of Variance and Dunn's multiple range test for post hoc comparisons (p  lt  0.05). Failure mode was evaluated with a scanning electron microscope. Changes in composite surface topography after H2O2 treatment were also investigated. Composite repair strength did not benefit from H2O2 treatment and adhesive application. Preliminary sandblasting significantly improved interfacial bond strength regardless of the intermediate agent applied. No changes in surface texture were produced after H2O2 treatment. An atypical fracture pattern was detected at the interfacial level between H2O2-treated composite surfaces and the overlying adhesive and composite. H2O2 treatment affected the composite-to-composite repair strength: a compromised resin polymerization may occur, resulting in a poor interfacial quality and a weak bond. Sandblasting still remains a reliable technique for composite repair.
