Then, they were divided into Group 1 and Group 2 for carbide and diamond bur preparation, respectively. Dental College and Hospital, Bengaluru, Karnataka, IndiaClick here for correspondence address and email Date of SubmissionAim: The aim of this study was to evaluate the shear bond strength (SBS) of self-adhering flowable composites on the dentinal surface prepared with carbide and diamond burs.Materials and Methods: A total of 64 extracted mandibular molars were mounted on acrylic resin blocks, and the coronal part of the dentin was exposed and polished. Three self-adhesive composites (Constic, DMG.Department of Conservative Dentistry and Endodontics, V. Be the first to review this product.Anithakumari Rangappa, Jyothi Srinivasulu, Vikram Rangaswamy, Sudhanva Eregowda, Vijayalakshmi Lakshminarasimhaiah, Usha LingareddyEnamel, dentin and nano-hybrid composite (Venus Diamond, Heraeus Kulzer, Germany) specimens were prepared. Skip to the beginning of the images gallery. Skip to the end of the images gallery. Statistically significant differences were seen in SBS values of Dyad-flow (Group B) ( P < 0.004) and Tetric N flow ( P < 0.007) for surfaces prepared with carbide and diamond burs.Conclusion: It was concluded that the SBS of Tetric-N Flow was higher than that of the experimental groups of Constic and Dyad-flow. The values between the groups were analyzed using Student's unpaired t-test.Results: Statistically significant differences in the SBS values were seen between Groups A and C ( P < 0.001) and Groups B and C ( P < 0.001). The values were subjected to ANOVA followed by Bonferroni post hoc analysis. Then, the specimens were stored in distilled water at 37☌ for 24 h, and then subjected to universal testing machine to evaluate the SBS and viewed under light stereomicroscope to evaluate the type of failure.Statistical Analysis: SPSS version 22 (IBM Corp) for Windows was used for statistical analysis. The remaining teeth were subdivided into Groups A, B, and C to be restored with Constic, Dyad™-flow, and Tetric N Flow composites, respectively. Starting from the introduction of acid etching by Michael Buonocore and introduction of BISGMA by Raphael Bowen 50 years back, the material has undergone significant changes in terms of formulation and clinical techniques.

Comparative evaluation of bond strength of self-adhering flowable composites to the dentin prepared with different burs: An in vitro study. Dentin bonding is further complicated by the formation of the smear layer which is created when dentin is cut or ground. However, composites have to be combined with good bonding agent for successful results. Flowable composites have the advantage of easy handling, lesser polymerization shrinkage, better marginal adaptation, and better wear resistance, thus indicated in preventive resin, small Class I, minimally invasive Class II proximal box, small Class III and Class V restorations. Mac world emulatorShows dentinal surface prepared with fissure carbide bur and shows dentinal surface prepared with coarse diamond bur. FG8642G (SS White) and those of Group 2 were prepared using coarse taper round end diamond bur SSW-TR13C (SS White). The samples of Group 1 were prepared using fissure carbide no. Then, the teeth were divided into two groups 1 and 2 of 32 teeth each. The teeth were mounted on acrylic resin blocks and the coronal one-third of the crown was sectioned exposing the flat dentinal surface and was polished using 600 grit silicon carbide abrasive paper. , A total of 64 extracted third molars were collected and stored in normal saline. ![]() The bond strength was recorded in Newton (N) and converted into Megapascal (MPa) using the following equation:Where mm 2 is the total surface area of the bonded composite.The Statistical Package for the Social Sciences version 22, IBM Corp, Armonk, IL, Chicago, USA, for Windows, was used for statistical analysis of data using ANOVA followed by Bonferroni post hoc analysis. SBS was evaluated using universal testing machine (Multi test 10i, Indian Institute of Science, Bengaluru, Karnataka, India), with a knife-edged rod of 0.5 mm width at a cross head speed of 1 mm/min applied at the dentin–composite interface parallel to the long axis of the tooth. In Group C, Tetric N Bond (Ivoclar Vivadent) self-etch adhesive was applied on the dentin surface and restored with Tetric N Flow (Ivoclar Vivadent) composite resin to prepare 3-mm disc and light cured for 15 s.Figure 1: Scanning electron micrograph of dentinal surface prepared with carbide burFigure 2: Scanning electron micrograph of dentinal surface prepared with diamond burThe samples were stored in distilled water for 24 h and were subjected to shear bond strength (SBS) test. V20) under ×20 magnification and classified as cohesive, adhesive, and mixed failures.All the three groups in carbide bur (Group 1) preparation showed higher SBS values than the same groups in diamond bur (Group 2) surface preparation. The bond failure modes were evaluated using a light stereomicroscope (Zeiss stereo Discovery. Results with P < 0.05 were considered statistically significant. , There is micromorphologic difference in dentin cut by diamond and carbide rotary instruments. SAFC combines the etching, bonding, and restorative procedures in a single step, thus simplifying and reducing the chairside time to the clinician and the patient.In this study, two self-adhering flowable composites, Constic and Dyad flow, and one conventional flowable composite, Tetric N Flow, were used to compare the SBS.In this study in carbide fissure group, all the flowable composites gave higher SBS values than that of the diamond group even though it was not statistically significant in Constic group, this is in agreement with the findings of Ogata et al. Gwinnett has reported that the thickness of the smear layer depends on the type of the bur, the use of water spray, and the speed of the instrument. Any tooth surface preparation with the rotary instrument generates smear layer. Table 1: Comparison of sheer strength of different restorative materials done under different preparations using ANOVA fld by Bonferroni post hoc analysis shows statistically insignificant difference ( P = 0.116) in SBS values of Constic (Group A) for surfaces prepared with carbide (Group 1) and diamond (Group 2) burs, with statistically significant difference ( P < 0.004) in SBS values of Dyad flow (Group B) and Tetric N flow (Group C) ( P < 0.007) for surfaces prepared with carbide and diamond burs.Table 2: Comparison of shear strength in Group A, B & C under different conditions using student unpaired t-testThe higher bond strength values showed predominantly mixed failure, whereas lower bond strength values showed adhesive failure.The clinical outcome of dental restorations bonded to dentine is dependent on the hybridization of adhesive resins into partially demineralized dentine.
