“…Additionally, it has been shown that the combined use of the Er,Cr:YSGG and diode 940 nm lasers provide an effective and safe method in removing the smear layer and simultaneously disinfecting straight canals [23,34,35]. The lasers settings tested in the present study have previously shown positive outcomes in removing the dental smear layer from curved root canals in endodontic treatment cases [24]. However, no study has been found regarding the effect of the alternate application of these wavelengths in dental retreatment investigations.…”

“…After consulting the statistical department at the RWTH Uniklinik-Aachen university and based on the outcome of the first part of our study [24], the number of samples was determined to be 24 human curved root canals. Teeth extracted due to periodontal reasons were collected, and the Patients' consent to use the teeth in our study was obtained.…”

“…Group C: dual wavelength laser treatment: Using the RFT2 tip, each canal was treated for 1 laser cycle with a speed of 1 mm/s. The settings applied were Er,Cr:YSGG (2 W, 50 μs, 20 Hz, water 80%, air 30%) and diode 940 nm laser (2 W, 50% duty cycle) [24]. Each sample received this treatment once before obturation and once after removing the gutta percha and reciprocation.…”

“…Those studies have shown positive results in removing the endodontic smear layer from straight root canals [23]. Additionally, a recent study [24] reported positive smear layer removal results using a new dual wavelength Er,Cr:YSGG and diode 940 nm laser protocol during root canal treatment of curved root canals. The safety of those setting on the root surface, periodontal tissues, and the surrounding bone has also been reported [25].…”

Purpose The aim of this quantitative study was to compare between a dual-wavelength laser (Er,Cr:YSGG, diode 940 nm) to the XP-Endoshaper/finisher combined with ethylenediaminetetraacetic acid (EDTA) 17% technique in removing secondary smear layer created during endodontic retreatment of curved canals. Methods Twenty-four human curved root canals were endodontically prepared and filled with AH-sealer and Reciproc® Gutta percha cones. The fillings were removed after 6 weeks, and the samples were randomly divided into 3 groups: A, negative control: irrigated with distilled water; B, XP-Endoshaper/finisher with EDTA 17%; and C Er,Cr:YSGG (2 W, 20 Hz, 50 μs) and diode 940 nm (2 W, 50% duty cycle). The canals were split longitudinally, and a laser scanning microscope (VK-X100K, VK-X200K, Keyence, Osaka, Japan) was used to capture images with the magnification of × 1000 from the canals. The images were scored by three blinded dentists using the Hülsmann scoring system, and a statistical analysis was carried out. Results A significant difference between the apical regions of groups B and C (p = 0.0010) was observed, with group C showing a cleaner apical region. However, this difference is cancelled out when comparing all areas of the canals (t = 1.43, df 21 p = 0.1663). Conclusion Within the limitations of this study, it can be concluded that a dual laser wavelength protocol (Er,Cr:YSGG (2 W, 20 Hz, 50 μs) and diode 940 nm (2 W, 50% duty cycle) may be positive in removing the secondary smear layer formed during endodontic retreatment cases of curved root canals.

“…Lasers are utilized in endodontic treatments to create access cavity preparation and to treat the dentin in the canal to remove the smear layer. Moreover, they are widely used and proved effective to disinfect the root canals and dentinal tubules [13,14]. In addition to the aforementioned areas, in recent years, the application of laser has gained momentum to stimulate the cells in studies on treatment and regeneration [15][16][17].…”

BackgroundsLasers and optics have extensively been used in dental procedures in recent years, so realizing the optical properties of the tooth represents a milestone in its successful applications. the aim of this study was to compare the absorption and transmission of applied wavelengths in 190-1100 nm range in various dentin thicknesses and the effect of changing the direction of beam emission in dentinal tubules.MethodsFifteen dentin specimens with a thickness of 300, 600, and 1000 µm and five specimens from each thickness were prepared by a transverse incision at the upper pulpal roof area of the human molars.Considering the Corono-apical and Apico-coronal direction, we measured the absorption and transmission of parallel light beams perpendicular to the dentin specimens in various thicknesses and two directions using a UV/ Visible spectrometer.ResultsThe ultraviolet wavelength's absorption rate was significantly higher than visible and infrared light irradiation from both directions in three thicknesses (p-value<0.001). Additionally, The radiation beam displacement had no significant differences in the absorption and transmission of ultraviolet, visible, and infrared light in any of the three thicknesses (p-value>0.05).ConclusionAccording to the results, the change in the beam direction during irradiation does not cause a significant difference in light absorption. Furthermore, the results are expected to develop a suitable method for evaluating the trans-dental performance of different optical parameters for diagnostic purposes in the dental tissues.
