4. INTRODUCTION
 The basic principles underlying the treatment of
teeth with endodontic problems are those
underlying surgery in general
 Cardinal principles of surgery
 Specifically, pain must be controlled if present
 During treatment, all pulp tissue must be
removed, the root canal enlarged and irrigated ,
the canal surface rendered sterile as determined
by bacteriologic examination, and root canal well

5. RUBBER DAM ISOLATION
 Application of rubber dam is imperative to
achieve a safe and aseptic operating technique
for endodontic treatment
 All endodontic operations should be performed
under the rubber dam
 Introduced by Dr. S C Burman in the year 1864

6. Advantages
 Dry aseptic field
 Protects patients soft tissue from sodium hypochlorite
irrigation and other caustic medicaments
 Prevention of aspirating endodontic instruments
 Access and visibility are improved
 Prevention of contamination of root canal with oral
microbial flora

7. COMPONENTS OD RUBBER DAM
KIT
 Rubber dam material
 Rubber dam clamps
 Rubber dam clamp carrying forceps
 Rubber dam punch
 Rubber dam frames
 Rubber dam templates
 Wedgets cord
 Dental silk floss
 Rubber dam napkin

8. TECHNIQUE OF RUBBER DAM
APPLICATION
 Application of rubber dam with high power suction
when used in conjunction with totally sterile
instruments may take care of infection control toa
greater extent
 When a clamp is used on an anterior tooth, the
rubber dam should first be slipped over the tooth ,
one should stretch th dam, over the tooth
between the thumb and the index finger of the left
hand, while the clamp is adjusted with the right
hand
 In posterior teeth, the clamp is preferrably
inserted half way into the previously punched
hole on the rubber dam , amd the arms of the
clamp are then spread apart with the fprceps

9. STERILIZATION OF
INSTRUMENTS
 It is significant to ensure optimal patient care,
eradication of existing infectious diseases and
preventing any new infections
 Endodontic instruments which are reusable have
to be autoclaved
 This should take the form of a clearly defined
process os decontamination

10. DECONTAMINATION CYLCE
 It is a combination of processes including
cleaning, disinfection and sterilization , used to
make reusable surgical instruments safe for
further use.
 The effective decontamination of reusable
medical devices is essential in reducing the risk of
transmission of infectious agents

11. Elements
 Use
 Cleaning
 disinfection
 Inspection
 Packaging
 Sterilization
 Storage

12. STERILIZATION
RECOMMENDATIONS
 It is preferable to protect the points of instruments
with cotton in order to prevent bag perforation
 Sterilize instruments with hinges in an open
position
 Allow drying cycle to finish completely
 Instruments that have been bagged are
considered sterilized for4 months if the bag is
intact
 Store it in a dry and low traffic area

13. COLD STERILIZATION
 The cold sterilizing solution consists of phenol ,
sodium tetraborate , glutaraldehyde and sodium
phenate , disinfects cleaned instruments in 10
minutes at room temperature , kills aerobic spore
formers including Bacillus subtilis in 3 hours and
achieves sterilization in 6.75 hours

14. GLASS BEAD STERILIZERS
 These sterilizers used to consists of either hot
salt or glass beads as a medium for dry heat
sterilization . The temperature range employed
was between 425-475 degree F
