Professional dentists have access to a variety of specialized dental equipment. Endodontic rotary systems are essential tools for endodontic specialists who specialize in treating roots and dental nerves. There are several different types of endodontic rotary systems, but all of them share the same general principle. Each system has its own strengths and weaknesses, depending on the user’s needs.
Different professions, such as general dentists, periodontists, and endodontists, may have slightly different needs for their equipment. However, many of these considerations will apply to anyone who uses endodontic rotary systems as part of their practice. The following are some examples of factors to take into account when shopping for your next endodontic rotary system.
Dental Rotary Systems for Root Canals
Root canals are used to treat teeth with damaged or diseased roots. Endodontic rotary systems are used in conjunction with a dental drill, which drills into the canal and removes the pulp from inside the tooth. There are several types of endodontic rotary systems for root canals.
The most common is a handpiece, which is driven by a dentist’s hands. Handpieces require the dentist to be close to the patient while they work on their tooth. Each type of endodontic rotary system has its own pros and cons. For example, cordless screwdrivers are portable but may require frequent charging if they’re going to be in use for an extended period of time. Handpieces have a limited range but allow users to keep their hands on the tooth while they work.
Types of Endodontic Rotary Systems
There are a variety of endodontic rotary systems to choose from. However, many people don’t know what they should be looking for. To help you out, here are the different types of endodontic rotary systems:
– Handpieces
These handpieces run on electricity and power cutting and shaping tools that reach into the mouth. They may be manual or electric, depending on your preference.
– Dental drills
Dental drills are used with a handpiece and can be cordless or corded, depending on your needs.
– Motors
Motors drive the cutting and shaping tools on an endodontic rotary system. Corded motors offer greater speed and power than their cordless counterparts but can be heavy while being moved around the mouth. Cordless motors are easier to use and transport but may not have as much speed or power as a corded motor.
– Handpiece attachments
Handpiece attachments come in different shapes and sizes, depending on what type of tooth is being treated. They also come in straight, round, tapered, ball-shaped tips for various purposes.
Speed While Rotating
The speed of rotation is one of the most important factors to take into account when shopping for an endodontic rotary system. Rotational speed will vary depending on the type of material you are working with. Some materials, like acrylic resin-based denture bases, require a slower rotation than other materials.
The slow speed will help to prevent bubbles and cracks in the material. Faster speeds are better suited for working with hard ceramic because they’re more durable and less likely to crack under stress.
Rotational Speed and Torque at the Tip
Endodontics rotary systems are fitted with a rotational drive that converts the linear motion of the handpiece into rotary motion. Most systems have an adjustable torque setting, which controls the speed and power applied by the tip.
As a general rule, high speeds provide more torque, but they also generate excess heat in hard tissues. Low speeds may require more time to complete the procedure, but they are gentler on softer tissues, making them preferable for extractions and wound closure.
Torque While Tungsten Is Rotating
When you are trying to purchase an endodontic rotary system, the torque on the tungsten should be a key consideration. Rotary systems usually have a torque range between 6-12 foot-pounds. This is important because it can help you determine how much power your endodontic system has and what types of tasks it is applicable for. For example, if you need a tool that can penetrate deeply into crevices and hard-to-reach areas, then you will want to invest in a higher torque range.
Low torque tools are better for general tasks such as smoothing and shaping root surfaces. Torque range isn’t the only thing to consider when purchasing an endodontic rotary system. You also need to take into account whether or not the system allows for variable speeds or just one constant speed. If you prefer variable speeds, then it’s best to invest in an electric rather than manual system.
How to Choose an Endodontic Rotary System?
There are many considerations to take into account when shopping for an endodontic rotary system. These considerations will depend on the profession, as well as the practitioner’s needs. In general, the following factors should be taken into account when choosing an endodontic rotary system:
-The type of handpiece that is being used
-The type of burr or file shank being used
-The number of speeds available
Conclusion
Choosing the correct endodontic rotary system for your needs can be confusing. There are many factors to consider and it is easy to miss one or more important details. This guide should help you narrow down which type of rotary system will work best for you. To make this decision, you need to first understand which type of equipment is best for each type of root canal.
From there, you can choose a rotary system with the appropriate speed and torque to suit your needs. With research, patience, and careful consideration, you should be able to find the right rotary system for your needs.
