Chapter 36: Moisture control Flashcards
describes the process of removing excess fluid and debris from the mouth.
oral evacuation
the two types of evacuators most often used in a dental procedure
saliva ejector
HVE
The main function of the _______ is to remove liquids from the mouth; it is not powerful enough to remove solid debris.
saliva ejector
uses of saliva ejector
-Prophylaxis
-Sealants
-Flouride treatmets
-Cementation of crown and bridge
-Orthodontic bonding
used to remove saliva, blood, water, and debris during a dental procedure.
HVE
The HVE has the following three main purposes:
- To keep the mouth free of saliva, blood, water, and debris
- To retract the tongue and cheek away
- To reduce the bacterial aerosol
The concern in a ______ procedure is the removal of blood, tissue, and debris, rather than a large amount of water and fluid.
surgical
The HVE is held in the ______ or _______
thumb to nose grasp
pen grasp
The two basic types of rinsing procedures used in dentistry are :
-limited-area rinsing
-complete mouth rinsing ( full mouth rinsing)
performed frequently throughout a procedure as debris accumulates during the preparation and restoration of a tooth.
frequently accomplished when the dentist exits the mouth and pauses for inspection.
limited area rinsing
this type of rinsing may be done after a long restorative procedure, after dental prophylaxis, or before patient dismissal following any dental procedure.
full mouth rinsing
To complete the rinsing process, the _________ is used for convenience and accuracy.
air water syringe
The three most common isolation methods
(1) cotton roll isolation,
(2) dry angles, and
(3) the dental dam.
this type of isolation is the most common type of isolation used for short procedures such as examinations, application of sealants, cementation of castings, and simple restorations.
cotton roll isolation
This pad helps isolate posterior areas in the maxillary and mandibular arches.
dry angle
placed on the buccal mucosa over the Stensen’s duct, which extends from the parotid gland and is located opposite the maxillary second molar
These pads block the flow of saliva and protect the tissues in this area.
dry angle
a thin, stretchable material that becomes a barrier when it is appropriately applied to selected teeth.
When this is in place, only selected teeth are visible through the dam
dental dam
The 6 × 6–inch dental dam size is used for applications on the posterior teeth in the _____ dentition.
The 5 × 5–inch size is used for primary dentition or for______ application on permanent dentition
permanaent
anterior
this dental dam thickness is selected when tissue retraction and extra resistance to tearing are important.
Examples of this include placement over a crown, a fixed bridge, or teeth with tight contacts.
heavy
this dental dam thickness is widely used in operative procedures because of its ease of handling and ability to isolate selected teeth.
medium
this dental dam thickness is most frequently used for endodontic applications. Because only one tooth is isolated, less stretch is required.
Thin
necessary to stabilize and stretch the dam, so it can fit tightly around the teeth but remain out of the operator’s way
dental dam frame
can be used and is placed between the patient’s face and the dam. The primary purpose of the this is to increase patient comfort by absorbing moisture
dental dam napkin
When the dam is placed, two types of lubricants may be selected
zinc oxide
or petroleum jelly
water soluble lubricant ( should not be used with rubber dam)
used for the placement and removal of the dental dam clamp
dental dam forceps
Dental Dam Stabilizing Methods
dental dam clamp
dental dam stabilizing cord,
compound wax.
the rounded portion of the clamp that extends through the dental dam
bow
encircle the tooth and are shaped into four prongs
jaws
The anchor tooth holds the _____ , and the keypunch hole covers the ____ _____ .
dental dam clamp
anchor tooth
In general, the holes are spaced with __ to __ mm between the edges, not the centers, of the holes
3.0
3.5
The isolation of anterior teeth occurs typically from _____ to _____
canine to canine
____________ are larger in circumference and designed with a straight or slight angle in the middle.
operative suction tips
The concern in a surgical procedure is the removal of _____, _____ & _____ rather than a large amount of water and fluid
blood, tissue, debris
Place the evacuator after the dentist positions the handpiece and the mouth mirror.
true or false
false. always place evacuator before the dentist positions handpiece and mouth mirror.
Frequent rinsing of the oral cavity maintains a ________ ______ _______ for the dentist and keeps the patient comfortable
clear operating field
the following features should characterize the isolation technique:
• Easy to apply
• Protective of soft and hard tissues
• Comfortable for the patient
• Retraction that provides better visualization for the operator
• Prevention of moisture contamination
• Isolation of the area of concern
designed to hold multiple cotton rolls in a more secure manner for the mandibular quadrant
cotton roll holder
The dental dam is routinely placed AFTER the local anesthetic has been administered.
t or f
true
are used to mark the dental dam with predetermined markings for average adult and pediatric arches
provides greater flexibility when one or more teeth in the arch are out of alignment.
Dental Dam Stamp and Template
always should be attached to the bow of the dental dam clamp as a ligature before the clamp is placed in the patient’s mouth.
dental floss or tape
