Can dental instruments be sharpened?
Waiting until you discover the scaler is too dull will eat into your clinical time, or worse, leave burnished calculus behind on your patients' root surfaces. Gradually sharpening dental instruments as they need it will prevent you from having to sharpen all of them at once.
What type of stone is used for sharpening instruments?
Ruby stones are primarily composed of aluminum oxide. The ruby stone is comparatively coarse, has a rapid cutting ability, and is used for sharpening instruments that are dull. Mounted stones are cylindrical in shape and appear in several sizes. They have a fine grit and are used with the straight handpiece.
How do you sharpen a dental hygiene instrument?
Arkansas Stones are a natural sharpening stone mined only in the Ouachita Mountains of Arkansas. They are quarried by blasting and the use of diamond saws. They are then cut into rectangular shaped whetstones to be used for sharpening knives and tools. Arkansas stones are made of Novaculite.
Use a Damp Cloth to Wipe: Use a paper towel or damp cloth to wipe the metal flecks away. When you wet the paper towel or clean cloth, ensure you wring the water out before using it to wipe the surface of your stone gently. Make sure you wipe off even the slightest metal fillings that settled on the surface.
Using oil for lubrication on your sharpening stone tends to be an older technique as it has been used with traditional sharpening stones. Most stones that are used today do not require oil since most people buy ceramic stones. Instead of using oil, water is the most common form of lubrication.
An India Stone is made from the man-made abrasive aluminum oxide. The term India Stone is a trade name for Norton's Aluminum Oxide sharpening stones. Norton's India stones are orange, tan or brown in color. This distinguishes them from Norton's Crystolon (silicon carbide) Stones which are gray in color.
How do I sharpen a Luxator? A special sharpening stone is available, suitable for all Luxator instruments from 1mm periotomes to Forte. To sharpen a periotome, place the concave surface of the tip of the blade on the sharpening stone and stroke away. Lift the blade after each stroke and repeat until the blad is sharp.
Slide one o-ring over the forceps to align and hold them closed. Apply one drop of instrument oil to the groove that will be used. Lightly swipe the tips perpendicular to the stone until the longer tip has been honed down to the desired length.
The curette features a sharp loop tip to aid in the removal of the uterine tissue. It is available as a rigid or malleable type to accommodate various cases.
There are no real tests you can do to determine the kind of stone, although you can get a practical appreciation for how it works — fine cutting or not, produces a scratchy or smooth or polished surface, how fast it cuts.
In the case of knife sharpening, motor oil is too thick or "heavy" and can over-lubricate or clog a sharpening stone, whereas WD-40 is too "light" an oil and will not carry the metal filings plus stone dust (collectively known as "swarf") away from the stone, and clog it.
Hold the instrument's handle firmly and orient the toe of the instrument toward your right or left side so you can see it. Then place the oiled, flat Arkansas stone on the toe at a 45-degree angle. Repeat the up-and-down motion around the entire toe from one side to the other. End the toe's sharpening on a down motion.
All of the following are local self-care methods for delivering chemical agents except one. Which one is the exception? When sharpening the toe of a curet with a moving stone, all are true except: turn instrument continuously until center of the round end of the blade is reached.
Washing the sharpening stone will remove any remaining metal filings and debris from your stone. Run the stone under warm water for 1-2 minutes to ensure that it is clean. Dry the stone with a clean, dry cloth or paper towel. Do not use soap or anything other than water to clean it.
Synthetic or artificial whetstones are made with bonded abrasives. These are commonly aluminium oxide, silicon carbide (a type of ceramic), or a diamond coating mounted on a metal sheet. Synthetic whetstones offer a consistent grit size, which allows for faster, more effective sharpening.
In the past, natural stones such as a Hard Black or Hard Translucent Arkansas were the finest stones available. More recently, waterstones have become the finest grit stones available with grits as high as 10,000, 16,000 and even 30,000.
Natural sharpening stones are normally composed of about 2/3 SiO2 (Silicon-dioxide), which provides the sharpening grit, and about 1/3 KAl2AlSi3O10(OH)2 (Sericite, finely rippled Muskovite) which serves as a bonding material.
