The aim of this study was to verify if low-level laser therapy could be useful to reduce chemotherapy-related oral mucositis grading and pain in childhood undergoing chemotherapy. A randomized double-blind clinical trial was carried out. Patients from 3 to 18 years of age undergoing cancer therapy and presenting OM grade 2 or more were eligible for this study. Patients were randomly divided in two groups: group A received laser therapy from the day of OM diagnosis and other 3 consecutive days (830 nm wavelength, power 150 mW, spot size 1 cm(2), 30 s per cm(2), energy density 4.5 J/cm(2)); group B received sham therapy (placebo) with the same timing. Two blind clinicians performed OM scoring and pain evaluation at day 1 (immediately before the beginning of laser treatment-T0), day 4 (after finishing laser therapy cycle-T1) and at day 7 (T2) as follow-up. A total of 123 patients were included in the study. Group A was composed of 62 children while group B is 61; in both groups, there was a progressive reduction in grade of OM, and at day 7, not every mucosal lesion disappeared. The difference in the decline of OM grading between the two groups resulted not statistically significant (p = 0.07). A statistically significant difference in pain reduction between two groups both at T1 and at T2 (p < 0.005) was observed. This study demonstrated the efficacy of LLLT in reducing pain due to chemotherapy-induced oral mucositis in children, while no significant benefit was noted in reducing OM grade.

MXenzymes, a promising class of catalytic therapeutic material, offer great potential for tumor treatment, but they encounter significant obstacles due to suboptimal catalytic efficiency and kinetics in the tumor microenvironment (TME). Herein, this study draws inspiration from the electronic structure of transition metal vanadium, proposing the leverage of TME specific-features to induce structural transformations in sheet-like vanadium carbide MXenzymes (TVMz). These transformations trigger cascading catalytic reactions that amplify oxidative stress, thereby significantly enhancing multimodal tumor therapy.

Purpose: The study assessed the clinical outcomes following treatment of peri-implant mucositis using Er:YAG laser or an ultrasonic device over six months. Patients' experience of pain, aesthetics, and Quality of life were further assessed.
Methods: One dental implant, per included patient, diagnosed with peri-implant mucositis underwent treatment with an Er:YAG laser (test) or an ultrasonic scaler (control) randomly.

This systematic review and meta-analysis aimed to compare the effect of photobiomodulation (PBM) therapy on implant stability and crestal bone loss placed in healed sites. The present systematic review and meta-analysis were conducted according to PRISMA (The Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. Two investigators carried out the electronic search of Pubmed, Google Scholar, and Ebscohost for published literature from 2012 till March 2024.

This study aimed to assess and compare the effectiveness of adding low-level laser therapy (LLLT) and neuromuscular electrical nerve stimulation (NMES) to conventional physical therapy exercises, for stroke patients with hemiplegic shoulder pain (HSP). Seventy-five stroke patients with shoulder pain were included in this prospective randomized controlled study. Participants were divided into three groups.

Objectives: To investigate if photobiomodulation (PBM) can reduce dentin hypersensitivity (DH) through a randomized, controlled, double-blind clinical trial.
Materials And Methods: One hundred and twelve patients experiencing DH after non-surgical scaling and root planing (SRP) were enrolled and divided into the Experimental Group - SRP + PBM (660 nm, 1.061 J/cm²) and the Control Group - SRP + PBM simulation.
