introduction: thermal changes in laser assisted root canal therapy with the use of diode laser can predispose tooth structure to the fracture. this study evaluated the changes in flexural strength of dentin blocks after diode laser irradiations (810 nm). methods: a total of 60 dentinal blocks were prepared from freshly extracted teeth in three different thicknesses (300, 500 and 1000μm) and 20 ...

according to the english literature, various lasers and light sources (i,g. argon ion lasers, pulsed ktp lasers, diode lasers and nd:yag lasers, pulsed dye laser(pdl), intense pulsed light sources (ipls) are applicable for the treatment of different vascular lesions. these conditions are the most important indication for laser therapy. this review summarizes the current literature on ipl with r...

introduction: the purpose of this case report is to analyze the results of vestibuleplasty around an over-denture based on dental implants to determine the evidence on the effectiveness of laser-assisted surgery and soft tissue management in implant dentistry. case report: the patient in this case report was a 57 year- old male who was completely edentulous, with a mandibular over denture based...

the application of laser in dentistry is considered as a favorable technique for patients due to its many advantages compare to other current methods. one of the main goals in pediatric dentistry is to provide the treatment as comfortable as possible without any risks for the care. laser is being used in different pediatric dental conditions including caries detection, caries removal and cavity...

today laser has a lot of usage in medicine and dentistry. in the field of dentistry, laser is used in soft tissue surgery, sterilization of canals (in root canal therapy) and in restorative dentistry laser is used for cavity preparation, caries removal, sealing the grooves (in preventive dentistry), etching enamel and dentin, composite polymerization and removal of tooth sensitivity. the use of...

background  recent investigations show that both proliferation and secretion of macromolecules by cells can be regulated by low level laser therapy (lllt). the aim of this study was to determine whether lllt could induce a bio-stimulatory effects on human gingival fibroblasts (hgf3-pi 53). therefore, the effect of laser irradiation on human gingival cell proliferation and collagen type i gene e...
