In addition, the linear motion of the piezoelectric tip that moves parallel to the tooth surface while never losing contact may be less painful for the patient as opposed to the elliptical motion of the magnetostrictive scaler
, which causes a "hammering" motion.
This study's purpose was to determine the effect commercially prepared disinfectant cleaning of dental unit waterlines (DUWL) had on the microbial quality of water emitted from 3-way syringes and power scalers
Twenty dental hygienists that had a high ultrasonic scaler
usage score were matched with 20 dental hygienists who had a low ultrasonic scaler
The type of dental hygiene procedure was classified as exam (intra- and extra-oral, dental, occlusal, and periodontal, including probing), scaling (manual scaling alone, or exam and manual scaling, but no polishing), complete prophylaxis (examination, scaling and polishing, or scaling and polishing if the examination had been completed at an earlier appointment), and appointments during which ultrasonic scalers
, sonic scalers
, or air polisher were used.
A pilot study was performed using two scalers
to determine how many sharpening strokes were required to remove at least one mg (threshold to represent ten times the sensitivity of the balance) of carbon steel.
Finally, the initial Project FreeSync-compatible scalers
from MStar, Novatek and Realtek will empower monitor vendors with robust DisplayPort receivers accommodating of FHD and QHD panels up to 144Hz, or UHD panels up to 60Hz.
On display at the Calibre stand will be a range of scalers
and processors made for small to large installations at any resolution up to 2K that includes advanced features such as geometry correction, projection mapping/image warping and soft edge blending.
Currently available for pre-ordering and slated for June 2007 distribution, the Gefen HDMI to HD-SDI (MSRP $1499) and HD-SDI to HDMI (MSRP $1299) Scalers
each come with an IR remote and RS-232 ports for menu control and selection.
Extron Electronics headquartered in Anaheim CA, is a leading manufacturer of professional A/V system integration products including computer video interfaces, switchers, matrix switchers, system controllers distribution amplifiers, audio products, speakers, video scalers
, scan converters, signal processing devices, Ethernet control interfaces, and high resolution cable
So says LNP Engineering Plastics, which supplied the Radel resin used by Hu-Friedy (Chicago) for the handle of its new manual dental scaler
and by PolyVac (Manchester, N.
The unsuitability of traditional scalers
to work in cross sections up to 18 m high called for the design of two special mining machines for underground roof control at the Norilsk mine in Siberia.
The product line includes vertical, horizontal and right angle grinders, die grinders, chipping hammers, rammers, air saws, air drills, air routers, scalers
, power supply motors, wheel guards, collets, SpiraCool pads, butts and peins, bushings, adapters and special accessories.
