Filter by:On January 30, 2020, the WHO (World Health Organization) declared the new coronavirus pandemic as the sixth public health emergency of international concern. In February 2020, the virus was designated by the Coronavirus Study Group of the International Committee on Virus Taxonomy as severe acute respiratory syndrome coronavirus 2. Many reports have described the appearance of olfactory or gustatory dysfunction simultaneously with other pre-established symptoms of COVID-19. Symptoms such as loss of taste or smell may appear 2 to 14 days after being infected with COVID-19. Worldwide, evidence regarding anosmia (loss of smell) and dysgeusia (change in taste) has been associated with COVID-19 infection. OBJECTIVES: To evaluate the effectiveness of low-intensity laser in treating changes in smell and taste after COVID-19 infection and map which changes obtained the best results. MATERIAL AND METHODS: This is an intervention study whose sample will consist of 30 individuals with loss of smell and taste for more than 6 months after COVID-19 infection, aged 18 years or older.
The objective of the study will be to investigate the effect of low-level diode laser therapy (LLLT) and steroid on facial nerve injury. Thirty five male Wistar rat will randomly be divided into five groups: healthy control (HCG); damage control (DC); laser (LG); steroid (SG); and combined laser and steroid group (LSG). Right facial nerve electromyography (EMG) data will record after facial nerve damage done and before sacrification at 4th week.The results will be evaluated histopathologically, electrophysiologically and biochemically.
The biggest problem in the orthodontic process is the pain and the long duration of treatment, which is also generally divided into 2 phases, namely the orthodontic tooth movement (OTM) and the retention phase. In recent decades, low-level-laser therapy has gained attention because it is non-invasive, inexpensive, relieves pain and has no significant adverse effects. Low-level-laser therapy (LLLT) has been proved to effectively induce and accelerate the remodeling process of alveolar bone by increasing the number of osteoblasts and osteoclasts. Therefore, LLLT is widely used in OTM to accelerate tooth displacement, but there are few studies and limited evidence on the stability whether it can strengthen and shorten the retention stage to avoid relapse. Thus, the purpose of this study is to investigate the stability after orthodontic treatment by observing the substantial influence of low-level-laser as during retention phase. Research Question(s) 1. Does the low-level laser treatment can enhance stability and shorten retention time after orthodontic treatment or not will be demonstrated through 3 aspects： 1. The Incisor Irregularities Index between laser and control group after application of LLLT at debond (0), 6 and 12 months of retention 2. The interarch dimension: intercanine width, intermolar width, interpremolar width, arch length between laser and control group after application of LLLT at debond (0), 6 and 12 months of retention 3. The overjet and overbite between laser and control group after application of LLLT at debond (0), 6 and 12 months of retention Objective General: The goal of this study is to investigate the stability in retention phase after application of LLLT during leveling and alignment with fixed appliances. Specific: 1. To compare the Incisor Irregularities Index between laser and control group after application of LLLT at debond (0), 6 and 12 months of retention 2. To compare the interarch dimension: intercanine width, intermolar width, interpremolar width, arch length between laser and control group after application of LLLT at debond (0), 6 and 12 months of retention To compare the overjet and overbite between laser and control group after application of LLLT at debond (0), 6 and 12 months of retention
The aim of this study is to evaluate the effects of high intensity laser therapy (HILT) on range of motion, pain, quality of life, muscle strength and femoral cartilage thickness in patients with knee osteoarthritis.
Background: Idiopathic Bell's palsy (IBP) is a unilateral facial paralysis of sudden onset and unknown etiology. Patient with IBP has an impaired facial expressions and psychological affection, which interfere with social communication. Multiwave locked system (MLS) laser therapy is a class IV laser with synchronizes emission of an 808 nm continuous laser and a 905 nm pulsed laser. It is proposed that MLS facilitates greater penetration and therapeutic effects than low-level laser therapy (LLLT). Aims: The aim of present study is to investigate the effect of MLS laser in the treatment of patients with unilateral IBP. Participant: A total number of 60 patients with IBP will be recruited from Makkah hospitals. Treatment will begin in the subacute phase as they referred from neuro-doctors. All the recruited patients will be randomly assigned into three groups of 20 patients each. Intervention: All patients will be treated with facial massage and exercises. In addition, group one will receive MLS laser with 10 J/cm2 in scanning mode while the group two will receive 10J/point for eight points. Measured variables: Facial disability scale (FDI) and House-Brackmann scale HBS will used to assess the grade of facial nerve recovery. The scores of both questionnaires will be collected at the baseline, after three and six weeks after treatment. Statistical Analysis: The Friedman and Wilcoxon signed ranks tests will be used to compare the FDI and HBS scores within each group
The present study is a clinical intervention applied to patients with urinary incontinence, with the intention of verifying the effects of the Pilates method associated or not with photobiomodulation with static magnetic field. The sample will consist of women with stress urinary incontinence from Bento Gonçalves attended at the school clinic of Faculdade Cenecista de Bento Gonçalves.
The study aim was to evaluate the effectiveness of Er:YAG dental laser treatment modality for cavity, sensitive teeth, abnormal frenum attachment and peri-implantitis.
Background: Recurrent vulvovaginal candidiasis (RVVC) is a common obstinate vulvovaginal inflammation in gynecology. At present, the pathogenesis of RVVC is not clear. In recent years, it is emphasized that the changes of vaginal microecological environment play an important role in the occurrence and development of RVVC. The treatment of RVVC can be divided into intensive treatment and consolidation treatment. Currently, local antifungal treatment is the main treatment regimen. While it is difficult and had an insufficient effect on prevention from recurrence of clinical signs and the improvement of vaginal mycological status in long term. Besides, there is no mature consolidation treatment regimen at home and abroad. Through the current application of the fractional CO2 laser in the treatment of atrophic vaginitis, it is confirmed that local irradiation of the fractional CO2 laser on vulva and vagina can regenerate and repair mucosal tissue, enhance the function of vaginal epithelial cells, gradually restore the normal pH value of vagina, improve vaginal microecological environment, restore the proportion of vaginal flora and reduce the recurrence rate of RVVC. This trial aims to explore the efficacy of two consolidation therapy schemes: the fractional CO2 laser and traditional antifungal drugs. Methods/Design: The ongoing study will include 200 RVVC patients who voluntarily joined the study and signed the informed consent form the Second Affiliated Hospital of WMU during December 2019 to March 2022. After patients were cured by transvaginal local drug intensive therapy, participants will be randomly divided into control group (n = 100) and experimental group (n = 100). The control group continue to receive a monthly course of vaginal local drug consolidation therapy for 6 months, while the experimental group will be given monthly local vaginal CO2 laser consolidation therapy for 3 months. The vaginal secretions samples of RVVC patients will be collected before intensive therapy, after intensive therapy and at the end of consolidation therapy, and the species abundance and structure of vaginal flora were detected and analyzed. In the same period, 5 healthy women of childbearing age were recruited as the normal control group and the volunteers do not take any treatment. The vaginal secretions samples of 5 volunteers will be collected when signing the informed consent to detect and analyze the species abundance and structure of vaginal flora. The patients with RVVC will be followed up for 3, 6 and 12 months after the treatment and vaginal secretions samples will be collected for vaginal flora structure detection to compare the vaginal microecological environment. For recurrent patients, the investigators will carry out targeted treatment, and again collect vaginal secretions sample to detect and analyze the species abundance and structure of vaginal flora. Objectives: The aim of this study is to compare the effects of fractional CO2 laser consolidation therapy and traditional antifungal consolidation therapy for RVVC, and assess the role of fractional CO2 laser in changes of vaginal microecological environment and recurrence rate of VVC after consolidation treatment.
The aims of this study will be to evaluate if a Lower Level Laser Therapy (LLLT): (1) enhances the levels of important pro-inflammatory chemokines involved in the bone remodeling process; (2) increases the rate of orthodontic tooth movement (OTM) on human subjects.
Surgical standard for treating traumatic burn injury scarring is to wait one year following the initial assault prior to beginning treatment. This study investigates the use of fractional ablative CO2 laser when begun within 3 months of a traumatic burn injury and it's impact on scar formation compared to the control. We hypothesized that early intervention would substantially mitigate the formation of scar tissue and help restore more normal appearing skin.
