Слайд 2: Saliva Ejector

You probably recognize a saliva ejector running because of the ambient noise it produces. The saliva ejector makes it easy to vacuum out intrusive saliva while performing an operation by way of the suction tubes. Don't worry though, as a saliva ejector will not dry out your mouth, only the excess saliva produced by the body during awkward mouth positions is filtered out by the machine.

Слайд 3: Dental Chair

The dental chair is probably the most prominent piece of dental equipment in the treatment room. Dentists either purchase brand new or refurbished dental chairs when they start public practice. Regardless of condition, comfort, stability, and utility are the three key factors that sets a good dental chair from a bad one.

Слайд 4: Examination Instruments

The dentists use examination instruments to peer into the mouth, look for the cause of the pain, and finally work on the damaged or infected tooth. The mouth mirror is used to peer into hard-to-view areas of the mouth, like the back and gaps of cavities. The mouth mirror is also used by the dentist to thump a tooth to see if it draws pain. The dental explorer has a hook that services a scraper for minor plaque and tartar buildup. It is also used to sensate the tooth and see if it produces any tingling sensation from the patient. The dental explorer's primary purpose is to determine if there is any tooth decay building up on the tooth. The periodontal probe is used to measure pocket depths in-between teeth. This probe is usually used on adult patients, since they are more prone to periodontitis. The probe is also used on patients who wear braces and Invisalign to see any improvements on their bite.

Слайд 7: Dental Drill

After pinpointing the cause of dental pain, and more often than not, a decayed molar, the dentist will need to excavate the tooth by using a dental drill. A dental can be attached to different removable tips/extensions (also called dental burs) and is capable of 400,000 rpm speeds, which is perfectly suited to penetrate the hard calcium surface of a tooth. A dental drill is primarily used in excavating a cavity prior to filling it with composite resin or amalgam. Upon filling a tooth with composite resin or amalgam, repairing chipped teeth or for purely cosmetic reasons, the use of a dental bur is imperative to smoothen the surface of the tooth.
