Problems to be paid attention to when using the bur

1. The selected bur should not be easily deformed, have high stability and fracture resistance, no tip collapse or sand-out, and good concentricity during rotation.

2. Appropriate force (30-60g) is applied when cutting, and the tooth tissue can be cut sequentially and effectively.

3. Attention should be paid to the speed of the bur, especially when operating large-diameter burs and coarse-grained burs. If the bur speed is too high, excessive heat will be generated, causing damage to the pulp and tooth tissue.

4. Do not insert the bur into the high speed turbine forcibly, check the handpiece and bur carefully if installation is difficult.

5. Disinfect the bur before each use. Burs should be cleaned frequently with a nylon brush or ultrasonic cleaner. Autoclave the burs at 135 degrees for at least 10 minutes.

6. After disinfection and cleaning, dry the bur and store it in a clean and dry environment.

7. It is common in clinical practice that the tip of the diamond bur wears faster than the tail end. At this time, pay attention to replacing the bur in time to avoid low cutting efficiency.

8. When using the high speed turbine cooling water spray, it should reach 50ml per minute.

9. After the tungsten steel bur is used, it should be cleaned and then disinfected with high temperature and high pressure. Do not use chlorine-containing disinfectant to soak the bur, otherwise the tungsten steel bur will become rusty and dull.
