Sterilization methods for high-speed dental handpieces

Hello everyone, I'm Jacky from Liangya Dental Clinic. Today I'll share with you the sterilization methods for high-speed handpieces. Cleaning: This can be done manually or mechanically. Regardless of the method, the core requirement is to remove contamination and ensure thorough cleaning. Pre-treatment: Pre-treatment should begin at the chair side. After each treatment, flush the handpiece for 30 seconds by stepping on the foot pedal. Remove the handpiece and bur, and wipe off surface contaminants. Place in a designated collection container. Maintenance: Dental handpieces should be lubricated and maintained after each cleaning and before sterilization. Use oil-based, not water-soluble, lubricating oil. Packaging: When using paper-plastic bags, ensure complete sealing with a sealing width ≥6mm, and the instrument should be ≥2.5cm from the bag seal. Disinfection and Sterilization: This should be done in a designated disinfection and sterilization room. For oral instruments, pressure steam sterilization is preferred, and disinfection and sterilization monitoring should be performed. After sterilization, check all physical parameters and chemical indicators. Only release for use after confirmation of compliance.

Why is a dental handpiece called a handpiece?

Hello everyone, I'm Jacky. Today, let's talk about why high-speed dental handpieces are called "handpieces". This "handpiece" is not that "handpiece". Dental handpieces frequently come into contact with patients' saliva, blood, or oral tissues. If not cleaned and disinfected properly, cross-infection is very likely! For dentists, a dental handpiece is a handheld tool that transmits (with or without a converter) the energy needed for dental tools or instruments. Dental handpieces are high-to-moderate risk oral instruments. Dental clinics need to follow the relevant regulations of the "Technical Specifications for Disinfection of Oral Medical Devices": to properly clean, maintain, disinfect, sterilize, and store "handpieces". With fifteen years of production experience, Liangya has high-speed handpieces with anti-back suction function that can prevent saliva and blood from entering the handpiece.

What is the purpose of a root canal length measuring instrument?

Hello everyone, I'm Jacky. Today I'm here to talk about the uses of root canal length measuring instruments. Root canal length measuring instruments are used in root canal treatment, mainly to help doctors accurately identify whether they have exceeded the safe area and whether they have reached the target area. The existence of root canal length measuring instruments has greatly assisted doctors in root canal treatment. Before the advent of root canal length measuring instruments, treatment could only rely on experience, and there was a probability of incomplete cleaning or exceeding the apex. Therefore, root canal length measuring instruments are a great help for root canal treatment.

What are the advantages of an oral anesthesia booster?

Hello everyone, I'm Jacky, and today I'm here to introduce the advantages of an oral anesthesia booster. Dental clinics use anesthesia boosters very frequently because they are needed for tooth extractions and surgeries. Therefore, anesthesia boosters are commonly used instruments for dentists. What are the advantages of an oral anesthesia booster? Compared to traditional syringes, it can achieve near painless injection of anesthetic. Those who have had intramuscular injections know that the initial prick is painless, but the injection itself can be quite painful. This is because manual injection relies on experience, which can lead to pain. However, the oral anesthesia booster delivers anesthetic at a constant speed, significantly reducing the pain.

History of Dental Handpieces

Dental handpieces have reached a high level of development today. But how did they evolve? In the late 18th century, the advent of hand-cranked dental drills marked a significant advancement in dental handpieces. In 1864, George Fellows Harrington invented a spring-driven drill, named Erado. Despite its considerable noise, its practicality and effectiveness were recognized. In 1868, Dr. George F. Green invented a foot-powered drill, further improving the efficiency of dental treatment. In 1871, James B. Morrison invented the car needle, used with a foot-powered drill, with a speed of up to 300 rpm. In 1875, Dr. George F. Green invented the first electric dental handpiece based on an electric motor, achieving a qualitative leap in speed and effectiveness, greatly facilitating the dentist's operation. During World War I, electric dental handpieces began to be widely adopted, reaching speeds of 3000 rpm. From the early to mid-20th century, the W&H brand continued to improve the design of dental handpieces, inventing modern mainstream push-button designs such as ball-button and roller-internal lock types. In 1949, John Patrick Walsh developed and patented a turbine air-driven handpiece with a speed of up to 400,000 rpm.

How long does a dental curing light last?

Many users frequently ask about the lifespan of a light-curing unit. Will it break easily? Currently, light-curing units use LED light sources. Their high efficiency, energy saving, and long lifespan have gradually made them the mainstream choice for dental light-curing lamps. The lifespan of LED light-curing lamps can be as long as tens of thousands of hours, greatly reducing the replacement frequency and lowering the cost of use. As for how easily it breaks, that depends on the price of the product you buy. Products costing tens of dollars and those costing hundreds of dollars will certainly have differences in raw materials. Therefore, sometimes, money that shouldn't be saved shouldn't be saved. Otherwise, constant repairs will be troublesome.

It's like mobile phones; Apple and domestic brands have almost the same functions, but the prices are vastly different. This is the brand effect. Ultimately, the purpose of a light curing machine is to improve our work efficiency. If it can achieve curing, they are all the same. Whether you buy an expensive one or a cheap one depends on your budget.

What is a dental curing light used for?

Hello everyone, today I'll be talking about the uses of dental curing lights. A curing light is a device that uses ultraviolet (UV) light or a specific wavelength light source to rapidly cure photosensitive materials. The curing light uses ultraviolet light to excite the photoinitiator in the resin, triggering a polymerization reaction that transforms the liquid material into a solid state. Often used for resin curing, it is used to cure composite resin materials, quickly completing treatments such as filling tooth defects and sealing cavities. It offers short and precise operation times.
