Moisture control is essential for endodontic treatment and dental procedures. Various methods and tools are used to isolate teeth and control moisture, including rubber dams, cotton rolls, high volume evacuators, saliva ejectors, cheek retractors, air/water syringes, and mouth props. Rubber dams provide the best isolation but can be difficult to apply. Cotton rolls and cellulose wafers are alternatives for brief isolation when rubber dams cannot be used. Proper moisture control provides benefits for both patients and operators by protecting the oral cavity and providing a dry, clean operating field.

2.  Endodontic ttt can not be expressed properly
unless the moisture in the mouth is properly
controlled

3.  Moisture control
 Retraction
 Harm prevention

4. Patient related:
A. Provides comfort to the
patient
B. Protect patients from
swallowing or
aspirating foreign
bodies
C. Protect patients soft
tissues by retracting
them.
Operator related:
A. A dry clean operative
field
B. Infection control
C. Increased accessibility to
operative site
D. Improved properties of
dental materials
E. Improved visibility & less
fogging of mirror
F. Prevents contamination
of tooth preparation.

5.  Saliva
 Tongue
 Mandible
 Lips & cheek
 Gingival tissue
 Buccal & lingual vestibule
 Floor of the mouth
 Adjacent teeth and restoration
 Respiratory moisture

6. 1. Rubber Dam

4. High volume evacuators & saliva ejector
5. Mirror & evacuator tip retractor
6. Mouth props
7. Air Water syringe
8. Cheek retractor
9. Drugs

8. A. Act as a raincoat for the tooth.
B. Complete, long term moisture
control.
C. Maximizes access and visibility.
D. Clean dry field while working.
E. Protect lips, cheeks & tongue
by keeping them aside.
F. Prevents accidental swallowing
or aspiration of foreign bodies.
G. Improves the properties of
dental materials
A. Takes time to be applied.
B. Communication with the
patient can be difficult.
C. Incorrect use may damage
porcelain crowns/gingival
tissues.
D. Insecure clamps can be
swallowed or aspirated.

9. Contraindication
 Asthmatic patients.
 Allergic to latex
 Mouth breathers
 Extremely malpositioned teeth
 Third molar (in some cases)

10.  Cotton rolls, gauze & cellulose wafers absorbents are
helpful for short period of isolation of the teeth
especially where rubber dam application is not
possible.
 Usually placed in Buccal & lingual sulcus specially
where salivary gland ducts exit, to as to absorb saliva.

11.  Throat shield is important specially when the
maxillary tooth is being treated.
 An unfold gauze is stretched over the tongue and
posterior part of the mouth.
 Avoid aspiration of restorations.

12.  It is used to remove water from air motor with high
suction speed.
 Also helps in retracting the soft tissues.

13.  A secondary function of the mirror and evacuator tip is
to retract the cheek, lip & tongue

14.  Mouth prop is also used to establish & maintain a
suitable mouth opening, thus help in tooth
preparation of posterior tooth.
 It is placed on the opposite to treatment side.
 Provides sufficient mouth opening for longer times.

15.  They are used to expand the mouth opening.
 This is usually use when working on the gingival
border of upper & lower front teeth and for the
adjustment of orthodontic bands.

16.  By air water syringe an air blast can be useful to dry
tooth and soft tissue during examination or used
during procedure.

17.  The use of drugs to control salivation is rarely
indicated in restorative therapy, and is generally
limited to atropine.
 Contraindicated for nursing mothers, and patients
with glaucoma.

18. By all these we can achieve a
moisture free mouth for better
operative and endodontic
procedure.

19.  When its not possible to isolate a tooth …. WHAT TO
DO?????
