Moisture control in dentistry is the removal of excess saliva from the patient mouth during any dental procedures or some dental procedures like amalgam filling, composite filling, root canal therapy, gingivectomy, alveolectomy, deep curettage, and many others.
As a dental assistant, you should be able to describe a way you can control moisture during dental procedures. A dental assistant should know the importance of surgery duties and office duties.
Why is Moisture control Important in Dentistry?
- Development of filling properties is active when there is no contamination in the area in which the procedure is been done.
- For clear visibility.
- When there is no contamination procedure it will be easier for example during filling.
- Easy visibility of the operating side of the oral cavity should be active.
- Remove saliva and water so that the patient won't swallow debris, blood or choking.
Oral Evacuation System
1. Saliva injector
This method removes saliva from the floor of the mouth. It could be used in conjunction with a rubber dam, cotton wool, gauze, for just a period of isolation such as teeth.
2. High volume oral evacuation
Uses of high volume oral evaluation
- Maintain the mouth free from, saliva, blood, water, and debris.
- Reduce the bacterial aerosol caused by the high-speed handpiece.
- It also retracts the tongue.
- The high-volume evacuator can also be used to separate the tongue from the cheek away from the mouth whenever a dentist is working on any procedures.
What are the types of high volume oral evaluation?
The surgical suction tip is used to control moisture in the anterior portion of the mouth while the operative suction tips are used generally during the procedure.
It is available straight or with a slight angle in the middle. All types have two beveled working ends. The bevel is slanted downward for use in the anterior portion of the mouth. It is your duties to place the evacuator in the patient’s mouth before the dentist positions the handpiece and the mouth mirror.
