Nowadays laser is extensively used in various industrial, communicative, medical, and other fields. Using laser in medicine has enabled physicians to perform the most accurate and finest operations within few minutes. Non-observance of safety points during laser performance could be seriously harmful for the medical staff and the patient. Therefore, in order to prevent the possible damage of th...
Background and Objective: Extraction of impacted lower third molars is one of the most frequent surgeries of the oral cavity. This operation might be accompanied by inevitable complications, such as pain, swelling, and trismus after surgery. Therefore, the aim of this study was to evaluate the impact of low-intensity/power laser therapy on swelling and trismus after impacted mandibular third mo...
the use of titanium and its alloys has increased in various industries recently, because of their superior properties of these alloys. titanium alloys are generally classified as difficult to machine materials because of their thermo-mechanical properties such as high strength-to-weight ratio and low thermal conductivity. laser assisted machining (lam) improves the machinability of high strengt...
any change in the refractive index of a laser active medium can lead to serious degradation of beam quality, laser beam modes, laser performance and variation in the intensity distribution. alteration in the refractive index of laser active medium is especially notable in high power lasers. it is clear that in the laser beam production, the pumping agent induces a great amount of heat which...
introduction: laser surgery as an alternative for conventional surgical procedure has gained special attention. using carbon dioxide (co2) laser has some benefits like less post-operative pain, swelling and infection, decrease in risk of metastasis and edema, and less bleeding providing dry sites for surgery. case report: a 12 years old boy with lingual frenum with indication for excision was r...
Dermatologic laser surgery is a continuously evolving field of medicine. According to the American Society for Dermatologic Surgery, in 2003, more than 100 million laser and light source cosmetic procedures were performed by its members. Procedures including hair removal and nonablative treatments, as well as removal of pigmented lesions, tattoos, and unwanted vascular lesions have revolutioniz...
Introduction: Different approaches have been developed to find the position of the internal auditory canal (IAC)in middle cranial fossa approach. A feasibility study was performed to investigate the combination of cone beam computed tomography (CBCT), optical coherence tomography (OCT), and laser ablation to assist a surgeon in a middle cranial fossa approach by outlining the internal auditory ...
