“…3,4 The findings of this study indicate that LAI was significantly more efficient in dentine debris removal in comparison to PUI, in agreement with the findings of the previous studies which used a plain fiber tip within the root canal. [12][13][14] In this study, however, a conical fiber tip was used in the pulp chamber without inserting it in the canal. This may be explained by the fact that the conical tip was able to transfer the laser energy along the root canal walls.…”

“…A diamond bur with a diameter of 2.3 mm was used to enlarge the coronal 3 mm of each tooth in order to simulate and standardize the pulp chamber. 12 Each sample was partly embedded in a putty impression material (Zetaplus ® ; Zhermack, Badia Polesine, Italy) to obtain a matrix, allowing the reassembly of the tooth halves for irrigation test after splitting (Fig. 1A).…”

“…[12][13][14] Laseractivated irrigation is performed using a plain fiber tip inserted within the root canal 5 mm away from the apex which, in turn, may exhibit undesirable side effects such as carbonization, cracking 15 and apical extrusion. 15,16 Therefore, using the fiber tip in the pulp chamber instead of inserting it within the canal is advocated.…”

“…It was suggested by Blanken et al (60) that the laser generates expansion and successive implosion of irrigants, in addition to causing a movement of fluids by a secondary cavitation effect. The LAI and passive ultrasonic irrigation were compared and the laser technique gave results which were comparable to the ultrasound technique that used in longer irrigation times (61,62). Debriding and cleaning efficacy of irrigation was enhanced by a new erbium laser technique coupled with a photoninduced photoacoustic streaming (PIPS) having a newly designed tapered tip with specific minimally ablative laser (63).…”

Introduction LASER (Light Amplification by Stimulated Emission of Radiation) was developed in 1960 by a scientist working for the Hughes Aircraft Corporation, Theodore Maiman, who proposed its mechanism based on the emitted beam coming from a ruby crystal (1).Lasers were tested for dental use first between 1970-1980, and laser devices such as carbon dioxide (CO 2 ) and neodymium:doped yttrium aluminum garnet (Nd:YAG) were considered suitable for hard dental tissues, while lasers were already in use for soft-tissue procedures in the middle of 1970s. Since then, many type of laser devices and applications have been used in dentistry, and new laser models and applications are still being created (2).The most common dental lasers in use today are erbium, Nd:YAG, diode, erbium, chromium doped: yttrium, scandium, gallium and garnet (Cr:YSGG), and CO 2 . Naturally, different types of lasers possess specific biological effects, are used in different procedures and, thus, are coupled with specific applicators. Nd:YAG LasersMarketed solely for dental use, these are the first true pulse lasers with a near infrared wavelength of 1064 nm (3). Primarily used for Öz 1971'de Weichman tarafından endodonti alanında ilk lazer uygulanmasının ardından, lazer teknolojisinin hızlı gelişimi ile yeni lazer cihazları ile ilgili çalışmalar hız kazanmıştır. Bu makalenin amacı, endodontide lazer uygulama alanlarıyla ilgili bilgileri güncellemek ve lazer cihazlarının avantaj ve kısıtlamaları hakkında bilgi vermektir.Since the first laser application in endodontics by Weichman in 1971, search for new laser devices is being proposed with the rapid development of laser technology. The purpose of this article is to update the information on laser application fields in endodontics and give information regarding the advantages and limitations of the laser devices.Received/Geliş Ta rihi :

“…26,27 The result is an enhanced removal of the smear layer as compared with passive irrigation with the endodontic needle. 28 Laser interaction with matter generating cavitation and subsequent pressure waves has also been described for the Nd:YAG. 29 A second aim of this study was then to investigate the effect of laser activation into the root-canal irrigant on root-canal wall cleanliness and the final seal obtained with the root filling.…”

Objective: This study investigates the effects of Nd:YAG laser irradiation combined with different irrigation protocols on the marginal seal of root fillings. Background data: Limited information exists regarding the effects of morphologic changes to root canal (RC) walls after Nd:YAG laser irradiation after smear-layer removal with EDTA on the sealing ability of root fillings. Methods: The 75 root-filled teeth (5Â15 teeth) were analyzed for through-and-through leakage by using capillary flow porometry (CFP). The RC cleaning procedure determined the assignment to a group: (1) irrigation with NaOCl 2.5% and EDTA 17% or standard protocol (SP), (2) SP þ Nd:YAG lasing (dried RC), (3) NaOCl 2.5% þ Nd:YAG lasing (dried RC), (4) SP þ Nd:YAG lasing (wet RC), or (5) NaOCl 2.5% þ Nd:YAG lasing (wet RC). Groups 1r to 5r consisted of the same filled teeth with resected apices up to the most apical point of the preparation length. Resection was performed after the first CFP measurement. Roots were filled with cold lateral condensation. CFP was used to assess minimum, mean flow and maximum pore diameters after 48 h, and immediately after these measurements, including root resection. Statistics were performed by using nonparametric tests ( p > 0.05). An additional three roots per group were submitted to SEM of the RC wall. Results: Through-and-through leakage was observed in all groups. Statistically significant differences were observed in maximum pore diameter: 1r > 3r, and 1r > 5r; in mean flow pore diameter: 1r > 2r, 2r < 4r ( p < 0.05). Typical Nd:YAG glazing effects were observed when the smear layer was present and exposed to the laser fiber (i.e., in the groups without use of EDTA) or when the fiber tip made direct contact with a smear-layer free RC wall. Conclusions: The reduction in through-and-through leakage is significantly higher with the Nd:YAG laser as smear-layer modifier than when smear layer is removed with an EDTA rinsing solution.
