“…en, the canals were washed with 5 mL of distilled water and dried with paper points. Group 3: an atmospheric plasma jet (MEDAiON; Nik Fanavaran Plasma, Iran) with a potential difference of 4.5 kV and a frequency of 80 kHz and argon gas with a flow rate of 3000 SCCM (3 L/min) were used for 1 min such that the nozzle head was positioned at a distance of 2 mm from the canal orifice [23].…”

Purpose. Debonding from the root canal dentin is the most common failure mode of fiber posts. This study aimed to assess the effects of cold atmospheric argon plasma (CAAP) and ethylenediaminetetraacetic acid (EDTA) on micro-push-out bond strength of fiber posts to root canal dentin. Materials and Methods. Forty maxillary canine teeth were decoronated, underwent endodontic treatment, and were stored in an incubator for 7 days. After post space preparation, the teeth were randomly divided into four groups for different surface treatments: (I) saline, (II) 17% EDTA, (III) CAAP, and (IV) 17% EDTA + CAAP. Fiber posts (Whitepost no. 2, FGM) were cemented into the root canals using Panavia F2.0 resin cement, and 1 mm-thick sections were made at the coronal, middle, and apical thirds of the roots. The samples underwent micro-push-out bond strength test. The mode of failure was also determined under a stereomicroscope. Data were analyzed using three-way ANOVA and Tukey’s post hoc test (α = 0.05). The mode of failure data were analyzed using the chi-square test. Results. The mean micro-push-out bond strength of fiber posts was not significantly different in the four groups ( P > 0.05 ). However, the bond strength values in the coronal third were significantly higher than the corresponding values in the apical third ( P = 0.01 ). There was no significant difference in the modes of failure between the groups ( P > 0.05 ). Conclusion. Application of CAAP alone or in combination with 17% EDTA could not successfully increase the bond strength of fiber posts to root canal dentin.

“…Even when plasma was used together with hydrophobic bonding, it could not produce higher bond strength than that of control group [ 35 ]. In addition, Valizade et al [ 36 ] showed that the microshear bond strength of repaired composite after cold plasma spray application slightly was improved but not significantly different from bur preparation, sandblasting, and Er,Cr:YSGG laser irradiation. Finally, it is worth mentioning that the differences in the type of bond strength tests, type of plasma, types of composite and adhesive systems used, would make the comparison of obtained results of our study and those of other studies so difficult.…”

Objectives: The purpose of this study was to compare the effect of plasma irradiation and other surface preparation methods on the microtensile bond strength of repaired resin composites. Materials and Methods: Twenty molds of a universal nanohybrid composite were prepared, aged and subjected to thermocycling. The specimens were divided into 5 groups for surface preparations including, C (Control): application of GC G-Premio Bond (GP) only; SB: sandblasting with alumina and GP; SI: application of phosphoric acid etching, silane, and unfilled resin; RB: roughening by diamond bur, phosphoric acid etching and GP; PL: application of argon and atmosphere plasma and then GP. The specimens were repaired with the new resin composite, cut to 1mm2 beam, and then subjected to thermocycling. The microtensile bond strengths were measured using a universal testing machine. The failure modes were assessed with a stereomicroscope. Data were analyzed using two-way ANOVA and Tukey's test. The level of significance was α=0.05. Results: The highest mean bond strength was found for the application of universal bonding GC GP in controls (26.62MPa) and the lowest average bond strength belonged to the SI groups (9.06MPa). The difference in the mean bond strength between the SI group and other groups was significant (P<0.05). The failure mode of specimens in all groups was predominantly adhesive. Conclusion: The application of GP as an intermediate universal adhesive established a proper bond between the old and new resin composite. In addition, the plasma application and other surface preparation methods did not significantly improve the bond strength.

“…Besides, plasma use widens the orifices of dentinal tubules and decreases the thickness of the smear layer [22]. The aim of applying non-thermal plasma technology is to improve the bond strength to enamel and dentin, increasing the surface energy to allow constructive interactions between the adhesive and substrate without increasing the surface temperature [6]. In the present study, argon was used because previous studies have shown that argon creates a hydrophilic surface more effectively than helium [23].…”

“…In the present study, argon was used because previous studies have shown that argon creates a hydrophilic surface more effectively than helium [23]. Non-thermal plasma increases surface energy and solid surface hydrophilicity by removing hydrocarbon groups and creating hydroxyl groups, allowing deeper penetration of adhesive monomers [6].…”

“…This technique improves the surface characteristics of dental materials and different substrates and increases their wettability. Surface preparation with CPS increases the surface energy, which is higher than other mechanical and chemical methods, preparing a clean and efficacious surface for bonding, with no change in the general inherent properties of the material [6].…”

Introduction: Currently, non-thermal plasma is used to modify the enamel and dentin surfaces to improve the bonding surface to dental composite resins. Non-thermal plasma creates a hydrophilic surface, decreases the contact angle, and improves the bonding quality. The present study aimed to evaluate the microshear bond strength (µSBS) of composite resins to dentin using different adhesive systems. Materials and Methods: Bovine incisor teeth were randomly assigned to three groups of G-Premio, Clearfil SE Bond, and Adper Single Bond adhesive groups after preparation. Each group was divided into two subgroups in terms of argon plasma surface preparation, and each subgroup was divided into two groups in terms of thermocycling (n=12). The microshear bond strength of the samples was determined using a universal testing machine. Three-way ANOVA was used to analyze the effect of the adhesive, plasma preparation, and thermocycling. Post hoc Tukey tests were used for two-by-two comparisons of µSBS. Statistical significance was set at P <0.05. Results: The results of the µSBS test showed that the application of plasma resulted in a significant increase in the mean µSBS in the G-Premio group, with no significant increase in the Clearfil SE bond and Adper Single groups. The effect of thermocycling after plasma application was significant only in the Adper Single group. Conclusion: The application of plasma might increase the bond strength of composite resins to dentin. However, further studies are necessary.
