BACKGROUND: Photobiomodulation (PBM) has been studied mainly for its effects on the repair, regeneration, and healing of tissue due to its direct and indirect actions on cell proliferation. However, it is necessary to consider the way in which laser acts, that is, whether it affects the rates of spontaneous mutation and mitotic recombination of cells. OBJECTIVE: This study investigated the genotoxic potential of PBM (904 nm) based on an in vivo bioassay that concomitantly evaluates mitotic recombination and point and chromosomal mutations...

OBJECTIVE: To evaluate the long-term effects of intense pulsed light (IPL) combined with meibomian gland expression (MGX) in the treatment of meibomian gland dysfunction (MGD). BACKGROUND: Although IPL has been proven to be effective in the treatment of MGD, any report regarding its long-term efficacy is unavailable by now. METHODS: The randomly selected study eye received a series of three IPL treatments that were applied directly on eyelids with an interval of 4 weeks (treatment energy, 14-16 J/cm2 )...

OBJECTIVE: Laser-assisted paraspinal microdiscectomy for far lateral lumbar disc herniation (LDH) enables direct access to the foraminal or far lateral zone with minimal tissue injury and preserves facet joints, thereby preventing postoperative segmental instability. We demonstrated the clinical outcomes of this technique and discussed the pros and cons of laser use in lumbar disc surgery. BACKGROUND: The microdiscectomy technique for L5-S1 far lateral zone may be difficult due to the limited surgical field with narrowed disc space, hypertrophied facet, and sacral ala...

OBJECTIVE: The goal of this study was to present our experience and results with patients who underwent percutaneous lumbar laser discectomy in our practice. METHODS: A total of 65 patients were included, and their charts were retrospectively reviewed. RESULTS: The most common level at which we performed the laser discectomy was the L5/S1 level 47...

BACKGROUND: Femtosecond laser mass spectrometry (FLMS) has become an important tool for investigation of chemical and biological materials in many areas from medical to industrial. OBJECTIVE: In medicine, the morphological examination of tissues is determined by performing pathological investigations under microscope. However, some novel improvements or developments must be performed for much faster diagnosis of the tissue during the operation when patient is under anesthesia...

OBJECTIVE: This study investigated light emitting diode (LED) treatment for patients with melasma on darker skin types. BACKGROUND: Melasma is a common disfiguring skin condition in women which is difficult to treat and is refractory. The cause of melasma remains unclear. METHODS: In this study, 60 female participants aged between 25 and 60 years, who presented with melasma, were enrolled (n = 39.85). They were purposely assigned to two groups according to their skin types...

OBJECTIVE: To determine surface roughness caused by Er:YAG laser irradiation and its effect on the increase in bacterial adhesion. BACKGROUND: Er:YAG laser was proposed as a strategic device to reduce caries by its ability to generate chemical and structural changes in tooth enamel; in turn, it produces undesirable effects on the tooth surface that could increase its roughness and allow a greater accumulation of microorganisms. METHODS: Eighty-four samples of human enamel were divided into seven groups (n = 12): G1_control (no laser irradiation); G2_100/H2 O, G3_200/H2 O, and G4_300/H2 O were irradiated with Er:YAG laser (12...

OBJECTIVE: The purpose of the present study was to investigate the long-term effect of pulsed Nd:YAG laser on the treatment of rotator cuff tendinopathy. METHODS: Sixty patients with rotator cuff tendinopathy participated and completed the study. The mean age was 50.2 ± 3.6 years. Participants were randomly assigned to one of two groups: the control group and the treatment group. Both groups were treated with an exercise program, in addition to the pulsed Nd:YAG laser received by the treatment group and the "sham" laser received by the control group, both for three sessions per week for 4 weeks...

OBJECTIVE: The aim of this study was to evaluate the influence of cavity preparation with different Er,Cr:YSGG laser handpieces on microleakage of different posterior composite restorations.
