Introdouction: Dentinal hypersensitivity (DH) is one of the most painful chronic problems reported in dental offices. Various methods have been applied for the treatment of DH. However, majority of them are either ineffective or last for a short period of time. It has been reported that lasers, particularly Neodymium- doped: Yttrium Aluminum Garnet laser (Nd: YAG), can be helpful in the treatme...

dentin hypersensitivity (dh) is a relatively common painful condition among dental problems. although many studies have been performed regarding the diagnosis and treatment of dh, dental practitioners are still confused about the definite diagnosis and treatment.the use of lasers as a treatment for dentin hypersensitivity was first introduced in 1985. laser treatment in dentin hypersensitivity ...

citric acid and tetracycline hcl are the most common clinical root demineralization agents used in periodontal practice. in this comparative in vitro study the effects of nd: yag laser radiation on root surface was compared to that of citric acid and tetracycline hcl using sem. a total of twenty-one freshly extracted periodontally diseased single rooted premolar teeth were root planned in vitro...

We report the operation of a diode-pumped monolithic self-Q-switched Cr,Nd:YAG laser in which the codoped ions create saturable absorption for Nd(3+) laser emission at 1064 nm. With a 70-microm beam diameter in the gain medium, the Q-switched pulse has a duration of 3.5 ns and a peak power of 2 kW. The output is linearly polarized with an extinction ratio of 600:1. The pulse-to-pulse intensity ...

Intratracheal combustion of a fiberoptic bronchoscope and an endotracheal tube occurred during the treatment of severe tracheal stenosis with the neodymium-YAG laser. This recognized hazard of CO2 laser surgery has not been reported previously with the use of the Nd-YAG laser. Fire hazard is inevitable when a laser is used in the airway, but the risk can be diminished. Rapid removal of the burn...

Background: To analyse the rate of complications associated with Nd YAG posterior capsulotomy. Methods: This prospective clinical study was conducted in Holy Family Hospital over a six-month period. It included five hundred and fifty patients in out door Eye Department, Holy Family Hospital treated with Nd YAG laser capsulotomy due to posterior capsular opacification after cataract surgery. The...

All-solid-state passively Q-switched lasers have advantages that include simple structure, high peak power, and short sub-nanosecond pulse width. Potentially, these can be applied in multiple settings, such as miniature light sources, laser medical treatment, remote sensing, precision processing. Cr4+:YAG crystal is an ideal Q-switch material for all-solid-state owing to its thermal conductivit...

Free beam laser endarterectomy (LE) and contact laser endarterectomy (CLE) were compared in 15 arteriosclerotic New Zealand white rabbits. The rabbits underwent balloon catheter trauma to the thoracoabdominal aorta and were fed a 2% cholesterol diet for 18 weeks. Thoracoabdominal exploration was performed under general anesthesia and multiple endarterectomies were performed in each rabbit. Athe...
