“…Degradation of the adhesive-dentin interface periodically is a substantial factor that contributes to the failure of dental composites. 1 An intimate bond between the adhesive and dentin certifies that the resin composite material would bear the adversities of the dynamic oral environment (temperature and pH fluctuations). 2 To improve the mechanical properties of dentin adhesives, researchers have tried various strategies.…”

The study aimed to synthesize calcium fluoride (CaF 2 ) nanoparticles and compare the push-out bond strength and viscosity of experimental adhesive (EA) and EA with 5 wt.% CaF 2 (CAF-5%). The CaF 2 nanoparticles were synthesized and then characterized with scanning electron microscopy (SEM)-energy-dispersive X-ray spectroscopy (EDX), Fourier transform infrared (FTIR), and micro-Raman spectroscopies. CaF 2 nanoparticles were incorporated in the adhesives to yield two groups; gp-1: EA-CAF-0% (control) and gp-2: CAF-5%. Canals of 20 teeth (N = 20) were prepared, and then yttria-stabilized tetragonal zirconia polycrystalline (Y-TZP) ceramic posts were cemented. Adhesives were assessed for push-out bond strength and rheology. CaF 2 filler was seen as irregularly shaped agglomerates on SEM. The EDX analysis demonstrated the presence of calcium and fluoride for the CAF-5% group. The FTIR indicated characteristic bands for CaF 2 containing materials. The micro-Raman spectra of CaF 2 nanoparticles demonstrated the presence of CaF 2 by showing strong bands at 840 cm À1 , 1380 cm -1, and 1400 cm À1 for fluorine and 950 cm À1 and 1080 cm À1 for calcium ions. The highest push-out bond strength values were obtained for CAF-5% group samples (cervical: 9.67 ± 1.46 MPa, apical: 8.66 ± 1.24 MPa), and both adhesives revealed adhesive-dentin interfacial fractures. The CAF-5% adhesive also revealed comparable rheological properties with the controls. The addition of CaF 2 nanoparticles in the adhesive improved its push-out bond strength to Y-TZP post and root dentin, although CAF-5% showed reduced viscosity on rheological assessment (compared with the controls).

“…MBP and CP are used in canal disinfection, on carries affected dentin (CAD), and as dentin and enamel conditioner and have shown promising outcome. [7][8][9] However work by Sayhon et al, advocates that CP has an unfavorable effect on mechanical properties of dentin and it does not improve bond values of fiber post. 10 Similarly, Strazzi Sayhon in his sequel study asserted that MBP for canal disinfection descends the bond value of fiber post to dentin.…”

“…11 PDT works on the principle of absorption of a photon from a low-intensity visible light source resulting in reactive oxygen species (ROS) instigating lysis of bacterial cell wall through the process of oxidation. 8 Ideally a photosensitizer should exhibit a low toxic effect on to host cell, produce ROS in a short period, water-soluble, and have an appropriate shelf life. None of the available photosensitizers confirm all the characteristics.…”

“…But the available evidence suggests that toluidine blue (TB) and Phycocyanin (P) closely fall to these characteristics but their use in dentistry is scarce and not reported. 8,9 To our knowledge from indexed literature, use of CP and MBP as canal disinfectant have shown to give conflicting outcomes. Moreover, the use of P and TB in sepsis of post space is still unprecedented.…”

Objective: To assess the effect of different photosensitizers activated by low-level laser therapy on EBS of glass fiber post to radicular dentin. Methods: This study was conducted at King Saud University from January 2021 to March 202. Fifty maxillary central incisors were sanitized and decoronated. NiTi was used for mechanical instrumentation of the canal. All canals were shaped, cleaned and obturated with gutta-percha. Post space was made using peso reamers. Four Division of groups were made according to photosensitizers used (n=10). Group-1: MBP at 100mg/l, Group-2: Phycocyanin at 100mg/l, Group-3: CP at 500mg/l, and Group-4 toluidine blue photosensitizer (TB). Lasers were used for activation of photosensitizers. In Group-5 samples were irrigated using sodium hypochlorite NaOCl +17% EDTA. Posts were cemented and teeth sectioned into apical, coronal and middle. For EBS all samples were subjected to a universal testing machine. Fracture patterns were analyzed using stereomicroscope. To compare EBS at different segments One-way analysis of variance (ANOVA) and Tukey multiple comparison tests (p=0.05) was performed. Results: The maximum value of EBS was shown in Group-2 radicular canal treated with CP with 17% EDTA at all three levels cervical (8.61±1.32 MPa), middle (6.81±0.73 MPa), and apical (5.51±0.25 MPa). Similarly, the minimum value of EBS was displayed in Group-5 canal irrigated with 2.25% NaOCl +17% EDTA (control) coronal (6.10±1.77 MPa), middle (5.11±0.75 MPa), and apical (3.60±0.94 MPa). Intragroup assessment disclosed a decrease in EBS from cervical one-third to apical one-third in all groups Conclusion: P, CP, and TB along with EDTA have the potential to be used as canal disinfectant and favors the bonding of GFP to radicular dentin using self-etch adhesive resin. doi: https://doi.org/10.12669/pjms.37.7.4331 How to cite this:Almadi KH, Alkahtany MF, Almutairi B.

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.
