increased duration of fixed orthodontic treatments leads to increased tooth root degeneration, gum inflammation and tooth caries. to decrease the time period of orthodontic treatment, it is essential to facilitate tooth movement or in other words increase the speed of bone remodeling. use of low level laser therapy is a method for achieving this goal.

introduction: : low level laser therapy (lllt) is gaining acceptance in clinical applications. for example, it is used as therapeutic modality in the repair of diabetic foot ulcer when conventional therapy was not effective, separately. the aim of this study is to determine the effect of local and travenous lllt for the healing of diabetic foot ulcer. methods:   this study contains 74 diabetic ...

introduction: post-endodontic treatment pain is a relatively common condition which needs analgesics for patient’s pain relief. low-level laser therapy (lllt) is suggested as a non-pharmacological and non-invasive treatment for dealing with painful conditions. the purpose of this study was to evaluate the pain relief effect of lllt after endodontic treatment. methods: eighty patients randomly r...

  Objective(s): 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 collage...

Background and Aim: Er,Cr:YSGG laser irradiation has been suggested as an effective method of cavity preparation and surface treatment to enhance the bond strength. The aim of this study was to assess the microshear bond strength of Fuji II LC glass ionomer (GI) cement to primary dentin following bur preparation and Er,Cr:YSGG irradiation. Materials and Methods: This in vitro, experimental stu...

Background: Vestibular Schwannoma (VS) is one of the skull base tumors originating from vestibular portion of eighth cranial nerve. Recently, 2 micro-Thulium laser is used in the surgery of some intracranial tumors. Objectives: Assessing the efficacy of 2 micro-Thulium flexible hand-held laser fiber (RevolixjrÒ) in microsurgical removal of VS. Materials and Methods: This retrospect...

Introduction: Mucogingival surgery is performed to correct defects in the morphology, position, and/or amount of gingiva. Such post-operative complications as bleeding, swelling, and pain have often been documented after mucogingival surgery and are associated with discomfort after surgery. The low-intensity laser has been used to promote analgesia. Low level laser therapy (LLLT) not only accel...

introduction: the purpose of this study was to evaluate amalgam surfaces treated by different output powers of erbium-doped yttrium aluminum garnet (er:yag) laser by scanning electron microscope (sem). methods: twenty-one amalgam blocks (8 mm × 8 mm, 3 mm thickness) were prepared by condensing silver amalgam (into putty impression material. after keeping them for 24 hours in distilled water, th...
