“…But when low power diode laser combined with toluidine blue as in group (IV) the percentage of reduction increased to 88.13%. These results were in agreement with the results of Sin (37) and results of López-Jiménez (18) who stated that photo activated disinfection is less efficient in reducing the numbers of Enterococcus faecalis. This result was in disagreement with the findings of Sarda (38) who stated that Photodynamic therapy PDT was an influential method in elimination of root canal microorganisms.…”

Introduction:The intent of the present research was to evaluate the antibacterial efficacy of the two different powers of diode laser and photodynamic therapy PDT by utilizing toluidine blue alone and in combination against Enterococcus faecalis. Methods:The research was done on seventy five human extracted incisor teeth. Their crowns were removed at cementoenamel junction CEJ then the roots were cleaned and shaped. After autoclaving of the roots, they were injected and infected with Enterococcus faecalis for 72 hours. They were divided randomly to five equal categories according to type of treatment used. Group (I), high power diode laser with wave length 980 nm and output power 2 W for one minute. Group (II), toluidine blue TBO photosensitizer for five minutes. Group (III), low power 635 nm diode laser with output power 220 mw for 30 seconds. Group (IV), toluidine blue was activated by low power diode laser 635 nm and output power 220 mw for 30 seconds. Group (V), toluidine blue was activated by 980 nm diode laser and output power 2 W for one minute.Results: Antibacterial efficacy was assessed before and after treatment. 980 nm diode laser reduced bacteria by 86.4 %, toluidine blue reduced it by 19.19%, 630 nm diode laser reduced it by 13.95%, toluidine blue plus low power 635 nm diode laser reduced it by 88.13 %, and toluidine blue plus high power 980 nm diode laser reduced it by 97.76 %. Conclusion:The most bacterial reduction was found in group toluidine blue plus high power 980 nm diode laser (group V). The combined technique could be an effective modality for elimination of Enterococcus faecalis from the root canals.

“…[1][2][3] Furthermore, the effects of laser light on the mechanisms of cavity preparation and dentin surface treatment 4,5 as well as the disinfection process 6 and various dimensions of tissue regeneration are evident. 7,8 These effects are currently well-used, and the applications of lasers and LEDs in various treatments of different areas of dentistry have received remarkable attention and proved to be highly efficient. [9][10][11][12] Lasers are used in endodontic treatments to assist in decay removal, to access cavity preparation, and to treat the dentin surface in the canal to remove the smear layer.…”

Introduction: Lasers and optics have been used extensively in dental procedures in recent years, and realizing the optical properties of the tooth is also an essential in its successful applications. The aim of this study was to compare the absorption and transmission of applied wavelengths in the range of 190–1100 nm at different dentin thicknesses and the effect of changing the direction of radiation emission on the dentin tubules. Methods: There were fifteen dentin specimens with thicknesses of 300, 600, and 1000 mm, five specimens for each thickness, prepared through a transverse section of the coronal dentin over the pulpal roof area of human molars. Considering the coronal-apical and apical-coronal directions, we measured the absorption and transmission of parallel light rays perpendicular to the dentin samples in different thicknesses and two directions with a Cecil CE 7400 UV/Vis spectrometer. Data analysis was performed using SPSS software version 19. P value<0.05 was considered significant. Results: The absorption rate of the ultraviolet wavelength range was significantly higher than that of visible and infrared light irradiation from both directions at three thicknesses (P<0.001). The radiation shift direction had no significant differences in the absorption and transmission of wavelengths of ultraviolet, visible, and infrared light in any of the three thicknesses (P>0.05). Conclusion: Accordingly, attenuation or transmission losses of light in the ultraviolet to infrared range clearly depend on the wavelength of light and the optical properties of dental dentin, and the thickness of the dentin used in this study has a little effect.

“…Recently, the role of xanthene-based photosensitizer Rose Bengal (RBP) has been investigated to evaluate its effects as an antimicrobial disinfectant against canal bacteria. 10 It is an anionic red or rose color dye that belongs to the tetrachloro-tetraiodo derivative of fluorescein. It absorbs light in the wavelength range of visible light 500–800 nm.…”

Objectives: To evaluate the effect of Rose Bengal (RB), methylene blue (MB) and curcumin used as a canal disinfectant on the extrusion bond strength (EBS) of FRCP (fiber reinforced composite resin) with canal dentin. Methods: The present invitro study was completed in 90 days approved by Riyadh Elm University. Forty premolars were extracted disinfected and decoronated. Mechanochemical preparation was done of canal space using 10k file widening canals sequentially with a 25K file with constant saline irrigation. Canal was dried condensed with gutta percha and sealer. Post space was prepared using peso reamer. Based on canal disinfection samples were divided into four groups. Group-1 MBP+17%EDTA, Group-2 RBP +17% EDTA, Group-3 Curcumin+17% EDTA and Group-4 5.25% NaOCl +17% EDTA. Following disinfection, the canal space of all specimens was washed with 17% EDTA for 120 sec. Post was cemented in canal space and cured. Specimens were placed on Universal testing machine (UTM) for EBS. The type of bond failure was evaluated using stereomicroscope. ANOVA and Tukey multiple comparison test was used to compare means. Results: Cervical third of Group-3 in which samples were disinfected with CP+17% EDTA displayed the maximum EBS (8.69±1.32 MPa). Whereas, the lowest EBS (3.30±0.54 MPa) was exhibited by the apical third of Group-4, where 5.25% NaOCl +17% EDTA was used as a canal disinfectant. The intragroup comparison demonstrated a declining trend of EBS from cervical to apical third in all investigated groups. Conclusion: Root canal dentin treated with different PS (MBP, CP, and RBP) demonstrated better EBS than the conventional disinfecting regime (NaOCl +17% EDTA). CP and RBP displayed better EBS than MBP. doi: https://doi.org/10.12669/pjms.38.1.4780 How to cite this:Niazi FH, Qamar Z, Noushad M, Khaled Bin Muhareb A.
