    From October 2005 to December 2008, transurethral ureterolithotripsy (TUL) with Holmium:yttrium-aluminum-garnet (Ho:YAG) laser was done for 21 patients. The success rates 2 and 12 weeks after TUL were 86.5% and 90.9%, respectively. Intraoperative laser-related ureteral perforation was seen in 4.7% (n=1). In conclusion, transurethral Ho: YAG laser ureterolithotripsy is a effective procedure for the upper urinary stones.

    A new technology for minimally invasive surgery such as natural orifice translumenal endoscopic surgery (NOTES) or single port surgery (SPS) has been introduced over the world. Laser-related new modalities such as confocal endoscopy, photodynamic therapy or image-guided laser therapy are also paid attention to as the most positive future medicine. However, it is very hard for us to obtain an approval as a medical device from the Japanese Government. It is now mandatory to make a long-term strategy for the worldwide marketing by collaboration among the industry, government and academic people.

    In 1996, Er:YAG laser was approved as a medical device for removal of carious tooth structures and cavity preparation in Japan. Since then, many reports have been published about the adhesion of dental restorative materials to Er:YAG laser-irradiated tooth structures, and almost all of them suggest negative effects on both enamel and dentin. This review article demonstrates the influences of laser settings and adhesive systems, and determines howto adhere effectively to Er:YAG laser-irradiated tooth surfaces.

    Application of laser to endodontics was first reported in 1967. In our department, the basic research about application of laser to endodontics was initiated in 1985. As for Er:YAG laser, it has been investigated since 1990, and its clinical use was approved in 1996. In this article, firstly the current problems in endodontics are discussed. Secondly, research concerning to laser performed in our department is described. Finally, clinical application of Er:YAG laser, including apicoectomy and repair of perforation is shown.

    This article describes the combined therapy of the intracanal endoscope and Er:YAG laser for the endodontic complications such as the removal of fractured instruments and intracanal foreign bodies. The use of Er:YAG laser under endoscopic observation allowed to conduct a minimally invasive therapy. This combined therapy might be promising in the solution of endodontic problems.

    Periodontal disease is defined by local inflammation due to infection with pathogenic bacteria, leading to loss of the supportive tissue around the involved teeth. For treatment of periodontitis it is essential to eliminate etiologic factors such as plaque and dental calculus. Since Er:YAG laser is capable of ablating hard tissues such as bone, dental root and calculus without thermal side effects, it has recently attracted more attention as novel periodontal treatment. Basic studies report that Er:YAG laser has high bactericidal capacity, detoxification effect and favorable root conditioning ability. Furthermore, several controlled clinical studies using Er:YAG laser obtained equivalent or better results compared with conventional mechanical therapy. In this paper, application of the Er:YAG laser for non-surgical and surgical periodontal therapy is discussed based on scientific evidence from currently available basic and clinical studies.

    The Er:YAG laser has been widely applied in dental treatments such as caries therapy, periodontal therapy, endodontic therapy, and dental implant therapy and demonstrated the excellent clinical effects since the laser is applicable to both soft and hard tissues. In the field of implant therapy, the Er:YAG laser can be applied to the following stages: gingivectomy, osseous surgery for implant bed preparation and LLLT for promotion of wound healing in the first phase of implant therapy, and gingival and bone tissue preparation for uncoverage of submerged implants in the second phase, and treatment of peri-implant lesions in the maintenance stage. Thus, currently the Er:YAG laser has become a promising laser in implant therapy and the further development of applications is expected. In the present paper, the clinical applications of the Er:YAG laser are introduced with the results of recent basic studies.

    Periodontal plastic surgery was recently defined as surgical procedures preformed to prevent or correct anatomic, developmental, traumatic or disease-induced defect of gingiva, alveolar mucosa or bone. It is an essential procedure for the patient to maintain their oral health and esthetic, and it is gradually spreading to general dentists. However, the procedure of periodontal plastic surgery is complicated and the success of it is depended on the skill and experience of operator. Presently, the Er:YAG laser is considered one of the most promising lasers in periodontal therapy due to its favorable performance for periodontal soft tissue procedures and hard tissue treatments. In this paper, the author introduced the effect of Er:YAG laser therapy on crown lengthening or root coverage in periodontal plastic surgery.

    In the pediatric dentistry, laser equipments were early and widely use throughout the clinic, because it was related with noninvasive methods.
    A laser treatment is accepts and supports by children, rather than conventional methods. In this review, we present of the summary and future direction of the study with lasers in pediatric dentistry, before and after using Er:YAG laser in clinic.

    Recently, the Er:YAG laser has received much attention since the laser is capable of effectively ablating both soft and hard periodontal tissues with minimal thermal side-effects. The high level Er:YAG laser has been increasingly used for periodontal therapy and implant/peri-implant therapy with successful clinical outcomes. Recent studies demonstrated that the low level Er:YAG laser promoted cell proliferation in vitro. However, the biologic effects of the Er:YAG laser on the surrounding tissues/cells have not been clarified in detail. In the present paper, the biologic effects of the low level Er:YAG laser in clinical application are discussed, based on scientific evidence from basic and in vivo studies.
