Toothpaste is a paste that is used to clean and improve the aesthetic appearance and health of teeth. It is also called gel dentifrice. It is mostly used in conjunction with a toothbrush. Toothpaste is used to promote good oral hygiene: it can aid in the removal of dental plaque and food from the teeth, it can aid in the elimination and/or masking of halitosis, and it can deliver active ingredients such as fluoride to prevent tooth and gums disease.

Top Loading Autoclaves are fully automatic, stand-alone, microprocessor-controlled & programmable systems. This autoclave incorporates a built-in steam generator and plug into a standard 120VAC (or 220VAC) power outlet. Top loading autoclaves are available in 100L or 150L sizes.

Topography is a computer assisted diagnostic tool that creates a three-dimensional map of the surface curvature of the cornea. The cornea is responsible for about 70 percent of the eye's focusing power. An eye with normal vision has an evenly rounded cornea, but if the cornea is too flat, too steep, or unevenly curved, less than perfect vision results. The advantage of corneal topography is its ability to detect irregular conditions invisible to most conventional testing. Corneal topography produces a detailed, visual description of the shape and power of the cornea. This type of analysis provides fine details regarding the condition of the corneal surface. These details are used to diagnose, monitor and treat various eye conditions. They are also used in fitting contact lenses and for planning surgery, including laser vision correction. For laser vision correction the corneal topography map is used in conjunction with other tests to determine exactly how much corneal tissue will be removed to correct vision and with what ablation pattern.

Topography based aberrometry system measures every variation of the entire optics of an eye from the cornea, to the retina. It provides data for the corneal aberrations. It derives a curvature map from topographical measurements. It then uses the data to calculate the wavefront error and incorporates it into the ablation profile of the laser. The surgeon can select the laser shot file of a patient from within the laser software.

Toric contact lens is a soft or rigid gas permeable (RPG) contact lens made especially for people with astigmatism. It is designed to comfortably fit the unique shape of eye. Toric lenses have two powers in them, created with curvatures at different angles.
