The energy available to treat the dental pulp after transmittance through overlying structures is clinically important for determining photobiological effects. This ex vivo study aimed to quantify laser energy delivery though the dental crown to the pulp from an initial energy of 5 J using four common laser wavelengths (λ = 450, 650, 810, and 980 nm).
The advantage of an endovenous laser therapy with 1470 nm is that the absorption coeffcient of water is 55 to 60 times higher at this wavelength than at 980 nm. Thus, a precise application of laser radiation into the vein wall can be performed. Furthermore, the treatment requires less total energy and shows lower heat generation.
This laser probe is very flexible and it is threaded into the fistula tract and then withdrawn as laser energy is being emitted. While the conical?laser probe is being pulled back slowly the tract is being closed.
A very common problem that causes pain, embarrassment, and confusion is fungal infection of the toenails. Often, people assume that nothing can be done about it and they resign themselves to a lifetime of simple neglect.
In recent years, different laser systems are used in endodontic field, which are effective for root canal disinfection. The diode laser is a compact device and now used in diverse areas of dentistry.
In a comparision operation, patients they used a laser with a wavelength of 980 nm which required 13 W power to seal the tract. For the rest of the patients, they used a laser with a wavelength of 1470 nm with 10 W power.
