dental foot control

Posted by duka on Wednesday, August 05, 2009 5:33:08 AM
Typical dental foot controls include a single lever that controls the speed of anair-powered or electrically-powered handpiece. Single-lever dental foot controls suffer from the disadvantage that they may be actuated from essentially a single position, so that as the dental professional moves around the patient it may be necessary to move the foot control. In addition, dual-lever foot controls are available, but they suffer from essentially the same problem.Various attempts have been made to address this problem by, for example,providing an actuator for the foot control that may essentially be actuated from any position around the foot control. Currently there are available dental foot controls with a disk actuator (a low angle cone, disposed over the base of the foot control) that provides increased accessibility for the dental professional.It has been found that the cord connecting these prior art foot controls (often called"rheostats"in the art) to the dental instrument and its point of connection to the foot control itself pose problems for the dental professional operator.

Dental autoclave

Posted by duka on Thursday, July 23, 2009 1:42:20 AM

Dental autoclave is used for sterilisation by a combination of heat (steam) and pressure (with vacuum in some cases) in the following areas:

  • Dental area (Dental autoclave, Dental sterilizer, CLASS B Autoclave)
  • Media preparation
  • Making laboratory waste safe prior to incineration or disposal
  • Glassware, instruments and apparatus sterilisation
  • Product sterilisation
  • Fluid and diluent sterilisation

  • Health care

dental light

Posted by duka on Wednesday, July 15, 2009 5:53:40 AM
The dental light   illuminates  the patient’s mouth and treatment area. It may be onceiling track or mounted to the DDS. Dental light  shouldbe properly positioned 30-36 inches from the patient’s face. Most dental light  mounted to the DDS consist of three major assemblies: the transformer and rigid arm assembly,  flex arm assembly,  and the light  head assembly. The intensity   switch   located   on   the transformer housing is used to set the intensity of the light to low, medium, or high settings. The dental light head rotates on three different axes. It can rotate as much as 180° horizontally, 125° vertically, and 45° diagonally from either side.

Dental Apex Locator

Posted by duka on Friday, July 03, 2009 8:45:31 AM

ROOT-SW apex finder (Dental Apex Locator) is a mature product in the international dental area and
dentist give it the good comment for its remarkable function and excellent
quality.

Features:
1) The Dental Apex Locator (Apex Locator) can accurately read the meter whether the canal is filed with blood, electrolytes   (hypochlorite, H20, saline)
2) The function of automatic conversion: the position of the file tip and meter reading are directly related, root canal enlargement can easily be performed while continuously monitoring the length of the canal electrically
3) Automatic monitor's audible signals set
4) Display: the meter is easy to read in the color wide screen liquid crystal display.

5) Fashionable and beautiful design, small volume, light weight and also easy to clean and 

    disinfect
6) Easy for operation; efficient, accurate and convenient for using without X ray radiation;

    enhance the standardize of the canal cure technology in clinic

Dental Syringe

Posted by duka on Wednesday, June 24, 2009 11:48:55 PM
A dental syringe is a kind of dental parts used by dentists for the injection of an anesthetic. It consists of a breech-loading syringe fitted with a sealed cartridge containing anesthetic solution.

The ancillary tool (generally part of a dental engine) used to supply either water or air to the oral cavity for the purpose of cleaning debris away from the area the dentist is working on, is also referred to as a dental syringe. A 3-way syringe has separate internal channels supplying air, water or a mist of air and water, created by combining the pressurized air with the waterflow. The syringe tip can be separated from the main body and replaced when necessary.

Curing Lights

Posted by duka on Thursday, June 18, 2009 7:00:53 AM
Polymerization in the dental practice requires highly energy rich blue light. Intensities of at least 1,000 mW/cm ? are considered to be ideal for achieving adequate composite polymerization results in short curing times (as of 10 seconds) or when curing indirect ceramic restorations. If this is not the case, complete curing of deeper layers is not ensured, which may lead to tooth sensitivity, discoloration, marginal gap formation and heightened wear.

It was interesting to note that every second curing light achieved a light intensity of only 500 mW/cm? or less and was there fore considered to be inefficient. It was quite alarming to find that most of the LED units tested showed extreme fluctuations of the light intensity and even clear deviations from the data provided by the manufacturers.

Fluctuations in LED units are caused by the differences in quality of the available light emitting diodes. As shown by the leading supplier of dental equipment and dental handpiece, the radiometric power of LEDs can fluctuate quite significantly between 275 and 1,050 milliwatts. As the radiometric power of LED s directly influences the light intensity of the polymerization light, considerable differences between the claimed and actual light intensity can occur in some curing lights.

As a consequence, the operator would have to compensate for this unacceptably high tolerance by extending the light curing time: According to the Total Energy Concept, the light-curing time has to be doubled if the light intensity is reduced by half. The problem in this case is the fact that the user does not know the actual intensity of the LED light.

Recommendations for dentists

The minimum value graranteed by the manufacturer is decisive. In addition, dentists are advised to test the intensity of their curing light with a radiometer at regular intervals. This will allow them to ensure adequate curing and there fore high-quality, long-lasting composite restorations.

Dental Handpiece

Posted by duka on Friday, June 12, 2009 3:53:54 AM

A dental drill (or dentist's drill) is a small, high-speed drill used in dentistry to remove decayed tooth material prior to the insertion of a dental filling. Dental drills are used in the treatment of dental caries. The term "dental drill" is considered the more colloquial form of the term "dental handpiece" although it can also be construed as to include the power source for one or more handpieces, a "dental engine." "Handpiece" and "engine" are more generic and euphemistic terms for generic dental tools.

Modern dental drills can rotate at up to 500,000 rpm,

and generally use hard metal alloy bitsfiles) known as 'burs'. Dental burs come in a great variety of shapes designed for specific applications. They are often made of steel with a tungsten carbide coating, or of tungsten carbide entirely. The bur may also have a diamond coating. (actually small rotary

Dental drills, which have a distinctive, shrill sound, are often a prominent factor in many people's fear of dentistry (dentophobia).
