What is the difference between a diamond bur and a carbide bur?
Overall carbide and diamond burs are functionally different. When using a carbide bur the bur is using small blades to slice away small pieces of the tooth while with diamond burs you are grinding the tooth down and leaving it with a rough surface that requires polishing later on with a separate tool.

What bur removes decay?
Dental caries are removed using a round tungsten carbide bur at a slow speed. Good sizes to select are sizes two, four, six, or eight. Using a round tungsten carbide bur at a slower speed removes only a minimal amount of dental hard tissue while more effectively removing the softer areas of decay.
Which bur is used for crown preparation?
The 5850-016 or 5850-018 diamond burs are used to develop the shoulder for anterior crown preparations. Depending on the desired extent of the shoulder; it may be confined to the facial surface of the tooth for a PFM crown, extended past the proximal contacts for PFM crown, or circumferential for an all ceramic crown.
What is tungsten carbide bur?
Tungsten carbide burs are 3 times stiffer than steel. Because Tungsten Carbide is such a hard material it is able to maintain sharpness, making it a highly effective cutting tool. Carbide burs cut and chip away the tooth structure rather than grinding as diamond burs do, this leaves a much smoother finish.
What are dental burs?
Dental burs are used for cutting hard tissues – tooth or bone. They are made of steel, stainless steel, tungsten carbide and diamond grit. There can be a bewildering range of dental burs in any dental catalogue, but for basic veterinary use only a few burs are needed.
What is a 330 bur?
Description. Short Pear Carbide Bur. 8-fluted. Measures 0.8 mm in diameter and is 1.6 mm long. Great for starting the occlusal portion with convergent walls for class II amalgam preparations and keeping the depth at 1.5 mm!
How are dental burs made?
They are normally made of stainless steel, diamond grit or particles, and tungsten carbide and fitted to a dental drill incorporating an air turbine. The dental bur was developed <300 years ago [8] and still widely used. The dental bur [4,8,9] has three parts: the head, the neck, and the shank.
