Background: Hemorrhoids are a common anorectal condition with a major medical and socioeconomic impact. Owing to the high incidence of symptomatic hemorrhoids in the adult population together with the risk of complications of traditional surgery, researchers are seeking less invasive methods of hemorrhoidal treatment.The aim of this study was to present our experience with the mini-invasive Doppler guided hemorrhoidal laser procedure (HeLP) in symptomatic 2nd and 3rd degree hemorrhoids with absent or minimal mucosal prolapse...

Background: The effects of Low Level Light Therapy (LLLT) on cellular function arise predominantly from stimulation of ATP production and reduction of oxidative stress. These effects are dose dependent and a function of beam irradiance and irradiation time. Human sperm motility has been shown to increase with LLLT irradiation. The objective of this study was to investigate the effects of laser and Light Emitting Diode (LED) LLLT photobiomodulation on human spermatozoa motility and DNA integrity...

Background and aims: Physical and chemical composition of dentin is subject to modification when irradiated with Er:YAG laser. Temperature rise causes water evaporation and micro-mechanical ablation of dentin. The misuse of laser parameters could affect negatively dentin collagen fibers leading to failure in bonded composite restorations. The aim of this in vitro study was to evaluate the effect of Er:YAG laser radiation at different levels of energy on the morphology of thermally affected dentin layer...

Background and aims: It is generally thought that bleeding from a hemangioma is difficult to stop. With development of the long pulse dye laser (LPDL), it has become possible to treat hemangioma with a large blood vessel diameter. Thus, it is effective in treating infantile hemangioma and pyogenic granuloma. Materials and methods: Five patients who visited our hospital from July 2015 to July 2017 due to hemorrhagic hemangioma were treated using a flash lamp excitation pulse dye laser with parameters of 7 mm spot size, 3 msec pulse width, fluence 12-14J/cm2 , DCD 30 msec, and delay 30 msec...
