How does the dental assistant assist the dentist in the treatment?

Rinsing the Oral Cavity
The dental assistant will want to rinse the patient’s mouth frequently to clear the debris for the dentist and keep the patient comfortable. The two types of rinsing procedures used for moisture control by the dental assistant include limited-area rinsing and full-mouth rinsing. To complete the rinsing process, the dental assistant uses the air-water syringe.

Limited-Area Rinsing – used when the dentist exits the mouth during a dental procedure and pauses for inspection. The dental assistant must do the rinsing in a way that doesn’t slow down the dental procedure.

Full-Mouth Rinsing – used when the patient’s entire mouth needs rinsing. Full-mouth rinsing may be used after a long restorative procedure.

Air-Water Syringe – connected to the dental unit and provides air, water or a combination of the two through a small sterile tip. The dental assistant will want to direct the syringe tip toward the tooth that the dentist is working on. They will also use the air on the mouth mirror continuously when the dentist is using it to see in back of the mouth. When the dental assistant hears a dentist pause, the dental assistant will want to rinse and dry the site.

Isolation of Teeth
During some procedures the teeth must be isolated to be kept dry. The three different types of isolation a dental assistant can use include cotton rolls, a dry-angle technique or a dental dam.

Cotton Roll Isolation – In addition to using dental suction unit to clean the patient's mouth, dental assistants also needs to place a pre-shaped cotton roll near the salivary gland ducts to absorb the flow of saliva. This type of isolation is used during examinations, sealant application, cement casting and other simple dental procedures.

Dry-Angle Isolation – isolation technique that uses a triangular absorbent pad. These pads block the flow of saliva and protect the tissues during a dental procedure. The dental assistant will want to replace the pad if they become soaked before the dental procedure is complete.

What is tooth wear?

Image
Decay is not the only cause of tooth destruction. Increasingly dentists are spending time restoring teeth that have lost their enamel due to erosion (damage from acid), attrition (tooth against tooth, nail biting, etc) and abrasion (e.g. vigorous tooth brushing). The increase in our average life span and the fact more teeth are being retained for longer means teeth are being exposed to these effects more than ever before. Acid erosion has been largely linked to the high consumption of soft drinks, both fruit juices and carbonated drinks. However, erosion is also seen in patients with symptoms of gastric reflux (heartburn) and in patients with eating disorders such as anorexia and bulimia. This is due to the highly acidic stomach contents coming into contact with the enamel of the teeth. Nocturnal tooth grinding is very common and might be exacerbated by stress and anxiety. It is the tooth to tooth contact that leads to the loss of tooth tissue. It can also lead to tooth

The causes of tooth discolouration are usually various and multifaceted. They have been classified as extrinsic, intrinsic and internalised discolouration. The extrinsic discolouration is associated with the use of tea, coffee, tobacco, some foods such as blueberries, and red wine. Intrinsic stains (dentin staining) may be due to systemic conditions, use of medications after the permanent teeth have erupted (e.g., minocycline) or during their development (tetracycline), childhood diseases, infection or trauma to a primary tooth while the underlying tooth is developing, trauma to a permanent tooth or natural aging changes and the accumulation of stain that has entered the teeth. There are many options, including over-the-counter treatments and prescription strength treatments professionally recommended that may be applied in-office by your dentist or by yourself at home.

So it is also important that they are self-cleaning at a temperature of 135ºC to allow for proper disinfection. B) Ultrasonic tips Ultrasonic tips, also known as inserts, are paired with each ultrasonic device, so generally each manufacturer produces and recommends their own tips.
