Sterilization and disinfection in prosthodonticsNishu Priya
Routinely dental care professionals are at an increased risk of crossinfection while treating patients. This occupational potential for disease transmission becomes evident initially when one realizes that most human microbial pathogens have been isolated from oral secretions. Because of repeated exposure to the microorganisms present in blood and saliva, the incidence of certain infectious diseases has been significantly higher among dental professionals than observed for the general population.

3. INTRODUCTION
CROSS INFECTION IS A MAJOR
ISSUE IN THE DENTAL CARE
SETTING BECAUSE OF CONCERNS
ABOUT TRANSMISSION OF DISEASE
via THE ORAL CAVITY.
www.indiandentalacademy.com
5. AIM
TO DEVELOP AND EVALUATE AN
EFFECTIVE CLEANING PROCEDURE FOR
ROTARY NICKEL-TITANIUM (Ni-Ti)
ENDODONTIC INSTRUMENTS
www.indiandentalacademy.com
6. Sterilization:
The process that destroys all types and
forms of microorganisms including
viruses, bacteria, fungi and bacterial
endospores.
www.indiandentalacademy.com
7. Disinfection:
A less lethal process than sterilization it
eliminates virtually all pathogenic
vegetative microorganisms, but not
necessarily all microbial forms (spores).
Disinfection is usually reserved for large
surfaces that cannot be sterilized.
Disinfection locks the margin of safety
afforded by sterilization procedures.
www.indiandentalacademy.com
8. Objectives of infection
control
Decrease the number of pathogenic
microbes to the level where normal body
resistance mechanisms can prevent
infection.
Break the cycle of infection from dentist,
assistant and patient and eliminate cross-
contamination.
Treat all patients and instruments as though
they could transmit an infectious disease.
Protect patients and personnel from infection.

9. Route of transmission of
microorganisms in the dental
field
Patient to dental team
Dental team to patient
Patient to patient
Dental office to the community
www.indiandentalacademy.com
10. Methods of sterilization
The four methods of sterilization that are
generally accepted in dentistry include
steam under pressure, chemical vapor,
dry heat sterilization and glutaraldehyde
solutions.
www.indiandentalacademy.com
11. Steam under pressure –
autoclaving
A temperature of 121°C, a pressure of 15lb is
used for 15 to 20 minutes. Denaturation and
Coagulation of microbial protein occurs during
exposure to high temperature of steam under
pressure. Advances in this method called
“flash” sterilization technique uses shorter time
with higher temperatures. There is however
greater chances for sterilization errors to occur
in this technique.
www.indiandentalacademy.com
12. Dry heat sterilization
They use hot air to kill microorganisms. The
technique requires a temperature of 160°C
for 2 hours.
Recently a rapid heat transfer sterilizer was
introduced operated at 190°C it will by rapid
airflow sterilize unpacked instruments in
6mins and packaged instruments in 12
minutes.
www.indiandentalacademy.com
14. Chemical vapour
sterilization
This method is based on the factors of heat,
water and chemical synergism. The chemicals
include alcohol, acetone, ketones and
formaldehydes.
The water content is below the 15% level, above
which rust, corrosion and dullness of metal occur.
The temperature requirements are 132°C for 20
minutes. The composition of heat and chemicals
is much kinder to metal surfaces than the other
techniques.

15. Portable unit for
premises disinfection
and
sterilization with
formaldehyde and
ammonia neutralization.
www.indiandentalacademy.com
17. Glutaraldehyde as
immersion chemical
steriliant :
For endodontic instruments sterilization by
heat is the method of choice, however the
use of glutaraldehyde preparations for the
chemical sterilization of heat sensitive
equipment has become a widespread
practice.
Glutaraldehyde kills microorganisms by
altering essential protein components.
www.indiandentalacademy.com
18. A 2.5% glutaraldehyde based
high-level disinfectant and cold
chemical steriliant. After activation
the solution has a 28 day activity
and can be reused during that
time.
Metricide 28 has a broad
spectrum activity against viruses,
bacteria, molds, fungi and other
vegetative organisms.
www.indiandentalacademy.com
19. Ethylene Oxide Gas (E.T.O.)
Ethylene oxide was first used as a sterilizing
agent in the late 1940’s. Since then ETO has
become an increasingly popular means of
sterilization especially in hospitals. It has high
penetration capacity. Temperature required
is low i.e. 25°C.
This makes it ideal for sterilizing heat
sensitive instruments. Time period required
for proper sterilization varies from 10 to 16
hours.
www.indiandentalacademy.com
20. Glass bead sterilizers
Chair side sterilization of endodontic files,
reamers and broaches can be accomplished
by using a glass bead sterilizer.
The transfer medium heats the endodontic
instrument through heat connection and kills
any adherent microorganisms.
At a temperature of 220°C contaminated
endodontic instruments require 15 seconds
to be sterilized.
www.indiandentalacademy.com
21. Glass Bead Sterilizer :
Used for sterilization of
instruments.
In few seconds you can
sterilize the instruments.

27. MATERIAL AND METHODS
Before the cleaning procedures,
instruments were used under simulated
clinical conditions to prepare canals of
extracted teeth
Scoring system
1. The entire surface of the flutes of each
instrument was examined at 45×
www.indiandentalacademy.com
28. MATERIAL AND METHODS
1. All instruments were immersed in Van
Gieson’s solution for 3 mins to stain any
biological debris
2. The instruments were rinsed using
distilled water and air-dried on an
endodontic stand
3. The category and extent of debris were
recorded using the criteria shown in the
table
www.indiandentalacademy.com
29. Scoring system for debris on instruments
Categories of debris
SD (stained particulate debris) : particulate matter stained red or orange
F ( organic film ) : a thin unstructured layer covering part of the
instrument surface and generally stained red
UD ( unstained particulate debris) : fine particles that did not exhibit any
red/orange coloration after staining
C : clean
Extent of stained debris
0 (none)
1 (film only)
2 (slight) : scattered particles spaced widely apart on the flute sufaces
3 (moderate) : numerous particles with areas of continuous coverage of
surfaces
4 (heavy) : areas of the instruments where the flutes were packed with
debris to there entire depth.
www.indiandentalacademy.com
30. Evaluation of different cleaning
procedures
Baseline levels of contamination
1. 40 new instruments were stained immediately after removal from
their packages
2. 20 instruments were contaminated by using them to prepare
canals of extracted and then stained after dry storage overnight
without any cleaning procedure
3. 20 instruments were contaminated by the same procedure , then
inserted into a sponge saturated with 0.1% Cholorhexidine
gluconate sol. For 2 hrs and stained in the same manner as the
dry storage group
www.indiandentalacademy.com
31. Experimental groups
80 instruments were used to instruments
canals of extracted teeth.
All instruments were inserted into a sponge
soaked in 0.1% chlorhexidine gluconate for 30
mins.
The instruments were then randomly assigned
into 4 equal groups representing four different
cleaning procedures
www.indiandentalacademy.com
32. Experimental groups
Group 1 : the instruments were placed in a
stand and the flues were brushed for 20
strokes per row with a nylon bristle brush
under running distilled water.
Group 2 : instruments were brushed as in grp 1
and then laced in a beaker containing 1%
NaOCl , soaked for 10 mins and rinsed under
running distilled water.
www.indiandentalacademy.com
33. Experimental groups
Group 3 : without brushing the instruments
were directly placed in a beaker containing
1% NaOCl for10 mins and the beaker was
placed into an ultrasonic bath.
Group 4 : instruments were brushed ,
immersed for 10 mins in 1% NaOCl , placed in
the ultrasonic bath for 5 mins and rinsed
www.indiandentalacademy.com
34. Experimental groups
After the cleaning procedures,
instruments were air dried and immersed
in Van Gieson’s solution for 3 mins,
rinsed under running distilled water and
air-dried on the endodontic stand.
Instruments were then scored for debris
at 45× magnification.
www.indiandentalacademy.com
35. Effect of storage conditions or
autoclave sterilization on cleaning
effectiveness
100 instruments from previous
experiments were cleaned using the
complete cycle
They were reused to instrument canals
of extracted teeth
They were divided into five equal groups
www.indiandentalacademy.com
36. Effect of storage conditions or
autoclave sterilization on cleaning
effectiveness
Group 1(dry-storage) : the instruments
were bench-dried overnight
Group 2(moist-storage): the instruments
were kept moist by placing them
overnight in a sponge soaked in
0.1%aqueous chlorhexidine gluconate.
With no additional cleaning
www.indiandentalacademy.com
37. Effect of storage conditions or
autoclave sterilization on cleaning
effectiveness
Group 3(dry storage, complete cleaning
sequence) : the instruments were bench-
dried overnight and were then transferred to
the brushing stand and subjected to the
complete cleaning sequence
Group 4(moist storage, complete cleaning
sequence) : the instruments were inserted
into a sponge soaked in 0.1% chlorhexidine
gluconate solution
www.indiandentalacademy.com
38. Effect of storage conditions or
autoclave sterilization on cleaning
effectiveness
Group 5(autoclave sterilization group) :
instruments were brushed on the
instrument stand and passed through
autoclave sterilization at 134ºc , 220kPa
for 3 min. the instrument were then
cleaned with the full cleaning protocol.
All instruments were stained and scored in
the same manner as before
www.indiandentalacademy.com
39. Biological risk analysis
Considering each instrument as one unit, the
instrument was classified as either positive
(stained debris or film present) or negative
(unstained debris only or clean) ‘biological
risk’
The presence of stained material in any
location of the instrument was considered to
constitute a biological risk.

44. Review of literature
Miller C. et. al. 2002
conducted a study on preparing instruments for sterilization
and concluded that moist storage after clinical use is
essential for a proper sterilization
Martins et. al. 2002
conducted a study on surface analysis of ProFile
instruments by SEM and reported that adherent deposits
containing carbon and sulphur, which originate from
lubricating oils used during manufacture serve as sites for
subsequent accumulation of debris during clinical use.
www.indiandentalacademy.com
45. Review of literature
Moorer & Wesselink 1982
conducted a study on the factors promoting the
tissue dissolving capability of sodium hypochlorite
and concluded that it’s tissue dissolving ability
does not depend only on it’s concentration but also
increased with mechanical agitation.
Tanomaru Filho et. al. 2001
recommended the use of the ultrasonic bath as
the most effective method to remove foreign
particles from the surface of the instruments.
www.indiandentalacademy.com
46. Conclusions
All new instruments should be cleaned and
sterilized before clinical use.
Instruments should be kept in moist storage
while waiting the cleaning process.
And that, no one method of cleaning is efficient
in complete removal of debris and that
methods are to be used in conjunct with others
for achieving proper sterilization
