“…We did not use EDTA in the current study since it has the potential to remove the smear layer after root canal preparation [32, 33]. Rather than using EDTA, the removal potential of Er,Cr:YSGG laser on smear layer was evaluated.…”

“…In order to decrease the amount of smear layer on root canal surfaces, irrigants and antiseptic agents are used, enhancing the effect of hand instrumentation and improving the efficiency of the sodium hypochlorite. However, studies have shown that a combination of NaOCl and EDTA remove the smear layer only partially [12, 32, 33]. In addition to this, Sen et al [34] investigated the antifungal effects of 0.12% chlorhexidine (CHX) and 1% and 5% NaOCl on C. albicans and concluded that both the smear layer and biofilms of C. albicans delayed or stopped the antifungal capacity of NaOCl and CHX.…”

Aim. To compare the disinfection effect of Er,Cr:YSGG laser using radial firing tips with NaOCI in root canals infected with C. albicans and to evaluate the irradiation effect on the dentinal surfaces. Material and Methods. In total seventy-six mandibular premolar teeth were used. In order to standardize the incubation and sterilization procedure, eight teeth were used. Sixty-eight of the root canals were incubated with C. albicans suspension for 72 hours. The specimens were divided into 5 experimental groups. Two groups were constituted as Group 1 was irradiated with 1.5 W laser (n = 8) and group 2, which was irradiated with 2 W laser (n = 8). Two more groups were formed as Group 3 (2 W laser (n = 25) and Group 4 NaOCI (5%) (n = 25). Group 5 (n = 2) did not receive any treatment. Mann-Whitney U and Kruskal-Wallis H tests were used to compare the different laser output powers. Wilcoxon Signed Ranks Test was used in order to compare the Candida cfu/ml levels according to treatment protocols (P < 0.05). Results. Both 1.5 W and 2 W laser resulted in a major reduction of C. albicans without a significant difference. The comparison of the dentin surfaces irradiated with Er,Cr:YSGG laser at two power settings resulted in similar morphological changes. However, NaOCI was found to be more effective in reduction of C. albicans than 2 W laser application. Conclusion. According to the results of the present study, the Er,Cr:YSGG laser with radial firing tips presented less antifungal effects on C. albicans in root canals of infected teeth than NaOCl solution.

“…With the development of root canal irrigation technologies, different modalities have become available such as conventional needle irrigation (CI), manual-dynamic irrigation (MDI), passive ultrasonic irrigation (PUI), and laser-activated irrigation (LAI) [5][6][7]. Andrabi et al [8] found that MDI allowed the irrigant solution to easily reach the apical third of the root through effective hydrodynamic activation. This method can also neutralize the vapor lock effect, thus improving the cleaning efficacy.…”

Background: The root canal cleaning efficacy of the photon-induced photoacoustic streaming (PIPS) mode in erbium-doped yttrium aluminum garnet (Er:YAG) lasers is controversial. Shock wave-enhanced emission photoacoustic streaming (SWEEPS), a novel mode in Er:YAG lasers, creates a strong shock wave in a narrow container. We accordingly hypothesized that it may effectively eliminate bacteria from narrow root canals. The present study aimed to compare the bacterial clearance efficacy between the SWEEPS and PIPS modes for Er:YAG lasers designed for root canal treatment.Methods: The distal and palatal roots of 130 freshly extracted human molars were used. The smear layer was first removed by conventional root canal preparation. All samples were then sterilized in an autoclave. The samples were subsequently exposed to Enterococcus faecalis and incubated for 4 weeks to establish E. faecalis infection models. The models were divided into three groups according to the irrigation method (n = 40 per group): 3% sodium hypochlorite (NaOCl) activated using the SWEEPS Er:YAG laser mode, 3% NaOCl activated using the PIPS Er:YAG laser mode, and 3% NaOCl without activation.Results: The bacterial clearance efficacy, based on the colony-forming unit count, was significantly higher in the SWEEPS group than in the PIPS and NaOCl groups. Moreover, scanning electron microscopy after irrigation revealed that the SWEEPS group had the least number of bacteria.Conclusions: The SWEEPS mode is more effective than the PIPS mode for eradicating E. faecalis from root canals.

Aim: The irrigation solutions and chelating agents are able to change the chemical composition of dentin. This study aimed to evaluate the efficacy of QMix on the removal of smear layer and the Ca/P ratio of root canal dentine after different exposure time periods. Material and Method: Sixty extracted teeth were prepared and divided into 5 groups according to the application time of the solution (n=12). In group 1, no irrigation was performed (control). The other groups were defined as follows consecutively; QMix solution were used for 1, 3, 5 and 10 minutes. Smear layer scores, erosion scores and Ca/P ratios of each group were evaluated by SEM and EDS. Results: In apical and middle regions, smear layer scores of 10 minute group, was significantly lower than 1 minute group (P<0.05). No peritubular or intertubular erosion was observed according to the erosion scores. Control group showed higher Ca/P ratio than the other groups without significant differences (P>0.05). Conclusion: QMix is able to remove smear layer effectively in 10 minutes without causing any erosion in dentinal tubules or alteration in the Ca/P ratio. Key words: QMix, Scanning electron microscope, Irrigation Öz Amaç: İrrigasyon solüsyonları ve şelasyon ajanları dentinin kimyasal kompozisyonunu değiştirebilmektedir. Bu çalışmanın amacı, farklı uygulama süreleri sonrası QMix'in smear tabakasını uzaklaştırma etkinliği ve kök kanal dentininde Ca/P oranına etkisini değerlendirmektir. Gereç ve Yöntem: Atmış adet çekilmiş diş şekillendirildi ve solüsyonun uyguşama sürelerine göre 5 gruba ayrıldı (n=12). Grup 1'de irrigasyon uygulanmadı (kontrol). Diğer gruplar sırasıyla şu şekilde tanımlandı; QMix solüsyonu 1, 3, 5 ve 10 dakika süre ile uygulandı. Smear tabakası skorları, erozyon skorları ve Ca/P oranı SEM ve EDS ile değerlendirildi. bulgular: Apikal ve orta bölgede smear tabakası skorları 10 dakika grubunda 1 dakika grubuna göre anlamlı derecede düşük çıktı (P<0.05). Erozyon sklorlarına açısından herhangi bir peritübüler veya intertübüler erozyon görülmedi. Kontrol grubunda diğer gruplara göre daha yüksek Ca/P oranı ortaya çıktı ancak anlamlı fark görülmedi (P>0.05). Sonuç: QMix dentin tübüllerinde herhangi bir erozyona yol açmadan ve Ca/P oranınada değişikliğe neden olmadan 10 dakika içerisinde smear tabakayı uzaklaştırabilmektedir.
