An air-water syringe is a metal device that is hooked up to both an air and water supply. The device has a long, thin tube in which the air and water are expelled. Two buttons are located on the air-water syringe; one button is for air and the other is for water. The dental assistant will commonly use the air button when trying to keep the field of view clear for the dentist. Debris and saliva will frequently make the area difficult to see, thereby making this tool a necessity. The dental assistant will utilize the water button when the area of the jaw that is being worked on needs to be rinsed off. This commonly occurs when filling a cavity or sealing a tooth.
The saliva ejector, which is often called a spit suction device, is a tool that is commonly used by dental assistants during most dental procedures. This instrument is usually white in color and has a handle attached to a flexible tube. The tube is attached to a suctioning device, which allows the dental assistant to use the saliva ejector to remove saliva from the mouth. This is important because patients are unable to swallow during most dental procedures, forcing saliva to accumulate in the mouth. Excess saliva can make it difficult or impossible for the dentist to do her work, which is why the saliva ejector is such an important piece of equipment.
High Volume Evacuator
The high volume evacuator is frequently used by dental assistants during oral surgery, root canals and fillings. This tool is similar in nature to the saliva ejector, though the tube is much wider. The diameter of the high volume evacuator can be as wide as 1/3 inch. This tool is used to remove any debris that may be in the mouth, such as tooth chips or food. If this debris were not removed, the patient could develop an infection or the procedure may not be able to be performed properly. Therefore, it is essential that this tool is used correctly by the dental assistant.
Sickle and Nabers Probes
Dentists use several types of probes to examine teeth and gum tissue. According to “Basic Guide to Dental Instruments,” the pointed tips of both the sickle/contra-angled probe and the Nabers probe allow tactile sensitivity useful for dental examination. Dentists use the sickle and Nabers probes for the detection of cavities, pits, fissures, and defective crowns or bridges. These probes come in several different styles and can be single- or double-ended.
The Briault probe is used in the detection of cavities on mesial or distal tooth surfaces. This probe has two angled ends useful in detecting decay between teeth, according to “Basic Guide to Dental Instruments.”
Dental tweezers, called “college tweezers,” can be used for “placing small objects in the mouth and retrieving small objects from the mouth,” according to “Basic Guide to Dental Instruments.” College tweezers may “lock” to prevent dropping materials though they also come in nonlocking varieties. The working ends of college tweezers can be straight or curved, and serrated or smooth.
Dentists also use metal or plastic rulers to measure length during dental examinations. These rulers may be calibrated for different units of measurement
Among dental assistants chief responsibilities is patient care. They prep the patient’s mouth for a dental procedure and make the patient comfortable. A pair of tweezers is a common setup tool found near the dental chair. Dental assistants and dentists frequently use college tweezers to manipulate small objects, such as cotton, in a patient’s mouth. Certain types of college tweezers lock once they grab an object so that it doesn’t slip from the dental assistant’s or dentist’s grasp.
Providing protective wear is part of the basic setup responsibilities of dental assistants. Most dental assistants and dentists wear a mask and rubber gloves. These prevent the spread of germs and bacteria. In addition, some dental assistants and dentists wear safety glasses or a face shield to avoid getting chemicals and debris in their eyes either when cleaning an instrument or during a dental procedure.
This is a condenser, also known as a plugger that is used to press the silver filling into place.
This instrument is used to carve and shape amalgam (silver) fillings.
A matrix band is used to separate the teeth while a white / tooth colored filling is placed.
A wooden wedge is used to slightly pry the teeth apart if a cavity is in between two teeth.
This is a curing light which is used to harden the filling material used for white / tooth colored fillings and also the material used for sealants.
A periodontal probe is used by a dentist or hygienist to measure the depths of a space between the tooth and gum.
A scaler is most often used during a dental cleaning to remove tartar, also known as calculus.
This is a spatula that the dentist or dental assistant uses to mix up specific materials.
This is a photo of an explorer. This instrument (along with a mouth mirror) is the instrument that a dentist and hygienist use on probably every patient.
These look like tweezers, but in dentistry they are called cotton pliers.
This is what the dentist sometimes uses to have the patient bite on to keep their mouth open.
This instrument is called an excavator. A dentist uses an excavator to remove decay from the tooth.
Root Canal Files
Root canal files are small instruments that increase in diameter and fit down into the canals of the tooth.
This is an amalgam well. The amalgam filling material is placed into this well after it is mixed.
Double Ended Amalgam Carrier
This instrument is called a double ended amalgam carrier.
