High-speed dental burs used in dentistry are usually used in conjunction with high-speed handpieces for cutting, chipping, drilling, and other operations on hard structures such as teeth, bones, and restorations in the oral cavity. The high-speed dental bur is composed of a dental bur handle, a neck, and a working end. According to the classification of the "Medical Device Classification Catalog", it belongs to the second-class medical device. There are many types of burs used in dentistry. Today, we will take you to understand the most commonly used dental burs when opening pulp and preparing holes in clinical operations.
The working end of the crack drill bur is a spiral design. Friends who have watched the videos "Understanding the Commonly Used Expanding Needles in Stomatology" and "Understanding the Commonly Used K-Type Root Canal Files in Stomatology" must know that this design has a strong cutting ability. Therefore, we often use split drill burs in clinical practice for pulp opening, tooth extraction, and hole preparation, which require rapid cutting of tooth tissue and rapid hole reaming.
It should be noted that because the working time required to extract the impacted teeth and cut the teeth is much longer than that of pulp opening, we often need to use an elongated split drill with an elevation handpiece. Ordinary split drills are more commonly used for pulp opening.
The working end of this dental bur is in the shape of a small ball, which is the ball drill we commonly use, and we often use it in clinical pulp opening. Sometimes, when fillings are needed to remove decay, or when a small amount of tooth tissue needs to be removed, a smaller ball drill is also used.
From the name, you can know that it is like an upside-down cone. Its end is very flat. We usually use it to trim the bottom of the cavity to be flatter.
This dental bur has a wide range of uses and can be used for many operations such as pulp opening, tooth preparation, hole preparation, etc. Its working end is usually covered with emery, and its cutting ability is relatively strong, so it is generally called clinically Emery.
In fact, the four kinds of dental burs we just talked about are relatively easy to identify, and the split drill, ball drill, and tapered bur have no specific requirements for their use. For example, some doctors prefer to use split burs. Some may like to use ball drills or tapered burs, this can be used flexibly. You can try to find a dental bur that suits your temperament. Because there are too many types of dental burs, the dental burs for full crowns, inlays, and veneers are also very finely divided, and many dental bur manufacturers have made special dental bur sets, such as inlay preparation sets and veneer preparation sets.
Even if it is the same type of dental bur, it has thick types and thin types, and there will be a color mark on the neck of the bur. This color sequence is the same as the order in which our hands use root canal instruments. From thin to thick, they are white, yellow, red, blue, green, and black, respectively. The coarser the corundum covered on the surface, the rougher it is prepared, but the stronger the cutting ability; the finer the diamond, the finer the preparation, but the weaker the cutting ability.

In clinical practice, we generally use fewer white dental burs. Usually, we use yellow high-speed burs for final finishing. The yellow dental bur seems to be smooth, but it is not. Its working end also has emery, but It is very dense, so it is usually used for final finishing. In clinical practice, black dental burs are rarely used for bulk cutting, but usually blue or green. The blue dental burs are usually medium in this model, and their cutting force and roughness after preparation are also in the medium level. It is the most commonly used dental bur for rough gear. Sometimes, we will find some high-speed dental burs that are not color-coded. This dental bur is generally equivalent to the blue-marked dental bur.
