DISCLAIMER:
Nothing in this blog should be considered dental advice. If you want that, you need to find a dentist, period. I am a dentist. I am also a writer. I publish all my articles with the understanding they will be read by dentists and dental assistants and could be used in a way that would be detrimental to their practice.
In other words, do not use this blog to provide your patient with dental care. If you have questions about dental care, dental procedures, or dental treatment options, please ask your dentist.
Controlled clinical trials are the scientific way to study dental care products, and the gold standard for proving the safety and efficacy of a dental care procedure or treatment. Although many products sold in health food stores and pharmacies are not tested in a clinical trial, there are often claims made on the package that the product has been scientifically proven safe and effective. Many of these products contain naturally occurring substances that are claimed to have benefits for the teeth or gum.
These products are most effective when used with toothbrushes that remove plaque and tartar. It is important to use them regularly. Too much may be harmful. Read the label. If you are unsure, talk to your dentist.
If the dentist recommends a treatment or product, find out what the results were for other patients. If the product is marketed as a home remedy, check to see if any scientific evidence supports the claims.
The information provided here is designed to augment, not replace, the relationship between a patient and his or her dentist. Please consult your dentist with any questions or concerns.

Sigmanest is a software package for the mathematical simulation of linear-circular-circular (LCC) coupled optical systems
which can also be used in free-space optics and industrial optics for the simulation and design of optical systems. The design
of laser optical elements is based on the conjugate gradient method for the optimization of the crystal or the wave front aberrations
that arise when laser light is propagated through or reflected from a crystal.
optical constants
This chapter presents the overall structure of the software and gives a brief introduction to the options and command syntax of the
interface. The command syntax is designed to allow the user to change the parameters of a crystal in a logical order, in the same
way as an electronic computer. In this way, the user is able to find out and eliminate a particular type of aberration. The command
syntax also allows the user to take into account the dispersion and diffraction properties of a crystal. The command syntax of the
software is optimized for the Crystal System.
The user must first install SigmaNEST software before using it. The interface allows the user to start the simulation of
the crystal by choosing either the simulation, the optimization or the data file functions. For the simulation function, the user
must choose the crystal geometry, the parameters of the laser, the power and wavelength of the laser, the laser polarization and
the system output. For the optimization function, the user must choose the crystal parameters and the optimization algorithm. For
the data file function, the user must choose the crystal geometry and the crystal type. Once a simulation is completed, the user
can set the size and position of the crystal in the window and run the optimization function to obtain the optimal parameters.
In addition to these choices, the user can modify the laser light position and the number of iterations by using the command
menu. After the optimization function is completed, the parameters of the crystal are stored in a data file, which can be used
in other simulations.
Sigmanest
Sigmanest software is divided into two components, the System Module and the Crystal Module. The System Module simulates the
optical system for laser light propagation, whereas the Crystal Module simulates the crystal for laser light propagation and
reflection.
Sigmanest software consists of a high-performance network computer with a multi-threaded processor, and a workstation to control
the high-performance
