“…In this study among the disinfection procedures, the lowest bond strenght values were observed in the Nd:YAG laser group, followed by the KTP laser group. Tarcin et al 20 Gurgan et al 28 and Nisar et al 27 's laser application results show parallelism with the results this study. In contrast to this study, Castro et al 29 and Kobayashi et al 30 They reported that Nd:YAG laser application increased the bond strength to dentin.…”

Effect of Self-Cured and Self-Etch Adhesive System on Shear Bond Strength After Photodynamic Therapy and Disinfection with Different Types of Lasers Ayşe Çeşme1-a*, Ihsan Hubbezoğlu1-b 1 Sivas Cumhuriyet University, Faculty of Dentistry, Department of Restorative Dentistry Sivas, Türkiye. ABSTRACT Objectives: The aim of this study was to investigate the strength of shear bonding of self-cured and self-etch adhesive systems to dentin after surface disinfection with Photodynamic Therapy (PDT), Er:YAG, Nd:YAG, and KTP laser. Materials and Methods: In the study, 6 main-groups were formed as Control, Er:YAG Laser, Nd: YAG Laser, KTP Laser, KTP Laser activated PDT and Diode Laser activated PDT. Each group was divided into two subgroups; Self-cured (Tokuyama Universal) and self-etch (Scotchbond Universal) adhesive system(n=10). 120 molar teeth were prepared to expose dentin surfaces. After disinfection and adhesive application, nanohybrid composite resin with a diameter of 3 mm and a height of 2 mm was applied to the dentin surface with the help of transparent molds. All samples were thermally cycled 5.000 times at 5°C and 55°C. Shear bond strength (SBS) test was applied to the samples in a universal test device. Results: The differences between the Er:YAG laser group and the control, KTP and Nd:YAG laser groups of the self-cured adhesive samples were statistically significant. While the differences between the Nd:YAG laser group and the PDT groups were statistically significant (p

“…Nisar et al 27 investigated the effects of KTP laser, Er:YAG laser, ozonated water, CHX, and Rose Bengal on the bond strength of the adhesive applied in self-etch mode to the caries-affected dentine. They emphasized that high shear bond strength was demonstrated in ozonated water followed by Er:YAG laser and KTP laser.…”

“…These findings can be explained by the fact that the SYMPA technique utilizing RB as a photosensitizer optimizes the SL removal by enhancing the availability of light distribution within the canal complexities leading to greater generation of ROS eventually cleaning the canal (Teed et al, 2023). Furthermore, RB is an anionic compound that binds to cationic calcium (Ca++) molecules in hydroxyapatite of dentin at the interface (Alkhudhairy & Aljamhan, 2023; Nisar et al, 2022). This also elucidates the high EBS of the canal disinfected with RB using the SYMPA technique.…”

Evaluation of the impact of the latest root canal disinfectant, that is carbon quantum dots (CQDs), synchronized microbubble‐photodynamic activation (SYMPA), and Nd: YAG laser along with ethylenediaminetetraacetic acid (EDTA) as a final irrigant on the Marten hardness (MH), smear layer (SL) removal, and extrusion bond strength (EBS) of zirconia post to the canal dentin. Eighty intact single‐rooted premolars were obtained and disinfected using 0.5% chloramine‐T solution. Root canal preparation was performed using ProTaper files followed by obturation. The post space was prepared for prefabricated zirconia post and all the teeth were randomly divided into four groups based on the disinfection used (n = 20 each) Group 1: 5.25% NaOCl + 17% EDTA (Control), Group 2: Nd: YAG laser + 17% EDTA, Group 3: SYMPA + 17% EDTA, and Group 4: CQDs + 17% EDTA. MH, SL removal, and EBS of zirconia post‐bonded to root dentin were performed using a microhardness tester, scanning electron microscope (SEM), and universal testing machine, respectively. Both intragroup and intergroup comparisons were performed using one‐way analysis of variance (ANOVA) and posthoc‐Tukey test for significant difference (p < .05). Group 2 samples (Nd: YAG laser + 17% EDTA) (0.24 ± 0.06 GPa) exhibited highest values of MH. Samples in group 3 (SYMPA + 17% EDTA) treated teeth unveiled the lowest MH scores (0.13 ± 0.02 GPa). Moreover, the coronal third of Group 3 specimens (SYMPA and 17% EDTA) (1.54 ± 0.31) eliminated SL from the canal with the greatest efficacy as well as presented the highest EBS (10.13 ± 0.69 MPa). However, the apical third of Group 1 samples (5.25% NaOCl + 17% EDTA) (2.95 ± 0.33) exhibited the least efficient elimination of SL from the radicular dentin as well as the lowest bond strength (5.11 ± 0.19 MPa) of zirconia post to the dentin. The SYMPA technique with 17% EDTA proved highly effective in removing the SL from canal dentin and enhancing the EBS of zirconia posts. The least preferable method for SL removal and MH improvement was found to be 5.25% NaOCl + 17% EDTA. CQDs and Nd: YAG laser demonstrated satisfactory smear layer removal properties from the canal, along with achieving appropriate bond strength of zirconia posts.Research Highlights Nd: YAG laser and 17% EDTA as canal disinfectant exhibited the highest values of MH. Specimens irrigated with SYMPA and 17% EDTA eliminated SL from the canal with the greatest efficacy. The coronal third of Group 3 (SYMPA + 17% EDTA) samples unveiled the highest zirconia post‐bond integrity score to the canal dentin. Cohesive failure was a dominant failure type among different experimental groups.

“…Modern restorative techniques demand the removal of the caries‐infected layer while retaining the CAD (Elhennawy et al, 2021; Franzon et al, 2015) However, past research has advocated that bacteria present within the CAD substrate may become the cause of recurrent caries at the tooth/restorative junction leading to restorative failure (Firouzmandi et al, 2019). Furthermore, the micro‐tensile bond strength (μTBS) of different adhesives bonded to the CAD surface is also considerably compromised in comparison to sound dentin (Nisar et al, 2022). Therefore, it becomes necessary to find an adhesive agent that can display both antimicrobial properties as well as strengthen the bond to the CAD.…”

To incorporate different concentrations of Al2O9Zr3 (1%, 5%, and 10%) nanoparticles (NP) into the ER adhesive and subsequently assess the impact of this addition on the degree of conversion, μTBS, and antimicrobial efficacy. The current research involved a wide‐ranging examination that merged various investigative techniques, including the application of scanning electron microscopy (SEM) for surface characterization of NP coupled with energy‐dispersive x‐ray spectroscopy (EDX), Fourier‐transform infrared (FTIR) spectroscopy, μTBS testing, and microbial analysis. Teeth were divided into four groups based on the application of modified and unmodified three‐step ER adhesive primer. Group 1 (0% Al2O9Zr3 NPs) Control, Group 2 (1% Al2O9Zr3 NPs), Group 3 (5% Al2O9Zr3 NPs), and Group 4 (10% Al2O9Zr3 NPs). EDX analysis of Al2O9Zr3 NPs was performed showing elemental distribution in synthesized NPs. Zirconium (Zr), Aluminum (Al), and Oxides (O2). After primer application, an assessment of the survival rate of Streptococcus mutans was completed. The FTIR spectra were analyzed to observe the characteristic peaks indicating the conversion of double bonds, both before and after the curing process, for the adhesive Etch and rinse containing 1,5,10 wt% Al2O9Zr3 NPs. μTBS and failure mode assessment were performed using a Universal Testing Machine (UTM) and stereomicroscope respectively. The μTBS and S.mutans survival rates comparison among different groups was performed using one‐way ANOVA and Tukey post hoc (p = .05). Group 4 (10 wt% Al2O9Zr3 NPs + ER adhesive) specimens exhibited the minimum survival of S.mutans (0.11 ± 0.02 CFU/mL). Nonetheless, Group 1 (0 wt% Al2O9Zr3 NPs + ER adhesive) displayed the maximum surviving S.mutans (0.52 ± 0.08 CFU/mL). Moreover, Group 2 (1 wt% Al2O9Zr3 NPs + ER adhesive) (21.22 ± 0.73 MPa) samples displayed highest μTBS. However, the bond strength was weakest in Group 1 (0 wt% Al2O9Zr3 NPs + ER adhesive) (14.13 ± 0.32 MPa) study samples. The etch‐and‐rinse adhesive exhibited enhanced antibacterial activity and micro‐tensile bond strength (μTBS) when 1% Al2O9Zr3 NPs was incorporated, as opposed to the control group. Nevertheless, the incorporation of Al2O9Zr3 NPs led to a decrease in DC.Research Highlights 10 wt% Al2O9Zr3 NPs + ER adhesive specimens exhibited the minimum survival of S.mutans. 1 wt% Al2O9Zr3 NPs + ER adhesive samples displayed the most strong composite/CAD bond. The highest DC was observed in Group 1: 0 wt% Al2O9Zr3 NPs + ER adhesive.
