Frequently Asked Questions (FAQs)
1. What should never be done with dental handpieces?
There are several things that should never be done with dental handpieces. These include immersing the handpiece to clean it, applying too much pressure to the burr, using damaged burs, using the handpiece at a pressure higher than recommended, using a high-speed handpiece without water, and dropping the handpiece. These practices can damage the handpiece and compromise its performance.
2. What are the three types of dental handpieces?
The three types of dental handpieces commonly used in dentistry are high-speed dental handpieces, electric dental handpieces, and low-speed dental handpieces. Each type has its own specific uses and advantages, catering to different dental procedures and requirements.
3. What are the parts of a dental handpiece?
A dental handpiece consists of three main parts: the handle, the neck, and the head. The handle is a long metal part that allows the dentist to grip the handpiece. The neck connects the handle and the head. The head is where dental burs are attached for scaling, cutting, and polishing teeth.
4. What is the life expectancy of a dental handpiece?
The life expectancy of a dental handpiece can vary depending on the model. In general, newer models have a life expectancy of 18 to 24 months, while older models may last closer to 12 months. Regular maintenance and proper care can help prolong the lifespan of a dental handpiece.
5. What are the common handpiece maintenance mistakes?
There are several common handpiece maintenance mistakes to avoid. These include poor autoclave maintenance, using a chemical wipe down before sterilizing, using an ultrasonic cleaner, removing a handpiece too early, lubricating the incorrect hole, failure to run handpieces after lubricating, and not cleaning the fiber optics. It is important to follow proper maintenance procedures to ensure the longevity and performance of the handpiece.
6. What is the difference between 1:1 and 1:5 handpiece?
The difference between a 1:1 and 1:5 handpiece lies in the gear ratio. A 1:5 handpiece offers higher speed and is suitable for heavier duty procedures like cavity preparations and crown cutting. On the other hand, a 1:1 handpiece is low speed and has a maximum rotation speed of 40,000rpm (electric) or 20,000rpm (air driven). The choice of handpiece depends on the specific dental procedure being performed.
7. How often should you oil your dental handpiece?
Dental handpieces should be lubricated and sterilized after each patient. Failure to do so can shorten the lifespan of the handpiece and pose a risk of cross-contamination between patients. It is important to refer to the operation manual for complete instructions on the proper use, lubrication, and sterilization of the handpiece.
