Some Possible Diseases Risk are Syphilis, Tuberculosis, AIDS and Hepatitis B, C, Influenza, Measles, Mumps, Rubella and Varicella, which are easily transferred to the Dentists, if safety protocols does not followed by the Dentists.
Standard Precaution, Use of Personal Protection equipment, Proper Disposable of waste material.
2. • Cross-infection during clinical practice can occur with
transmission of infectious agents between patients
and health workers in a clinical environment.
• Persons who seek dental care could be in the
prodromal phase or being carriers of certain
infectious diseases, without knowing about their
physical conditions.
• In addition, some infectious diseases have
prolonged incubation periods or post-infection
“window period” during which antibodies can’t be
detected
3. • Needles, other sharp objects, spatter, and
aerosols can transmit various viral and life
threatening infections including some
respiratory disorders.
• Blood or saliva splashes to the eyes / nose /
mouth occur frequently during dental
treatment.
4. POSSIBLE DISEASE RISK
• Bacterial infections like
syphilis and tuberculosis.
• Life-threatening infections
such as AIDS and hepatitis
B.
• Hepatitis C
• Influenza, measles, mumps,
rubella and varicella.

6. Direct
Transmission
Indirect
Transmission
Airborne
Transmission
MODE OF TRANSMISSION OF
DISEASES
Occurs through mode of inhalation. Many
serious disease spread via air.
When dental professional comes in contact with
contaminated surface without personal protective
equipment.
Through infected blood, saliva, or other
potentially infectious materials
7. • Herpes simplex infection can be transmitted
around the lips and conjunctiva via
contaminated hands of the operator.
• Contamination with droplets from the saliva
of patient can cause tuberculosis.
• Direct blood contact by a needle/sharp
instrument can transmit hepatitis viruses B,
C, and D.
• Through Lesions on the operators hand.
8.
9. • Via splashed material from patients mouth on
operator's face, especially the eyes may
somewhat increase the risk of HBV and HIV.
• Unsterilized instruments can spread HBV and
HIV.
• High-speed rotary instruments and ultrasonic
scalers through droplets can lead to
respiratory diseases via viruses and bacteria.
10. PREVENTION OF DISEASE
TRANSMISSION
• Standard precautions are designed to protect dental
health care personnel and to prevent personnel from
infecting patients with organisms that can be spread
by blood or other body fluids.
• Maintenance of high standard measures of
preventing infection is of utmost importance both
for the patient as well as the operator to avoid cross-
contamination.
13. • High-level disinfection/ sterilization protocol
• Use of surgical wear (gloves, gowns, masks,
Protective eye wear)
• Safe injection practices
• Maintaining hand hygiene with neutral pH
liquid soap or use alcoholic hand gels.
14. • Reusable or disposable gowns in case of HIV,
HBV. Laboratory coats, or uniforms may be
washed, using a normal laundry cycle.
• Aluminum foil, or clear plastic wrap may be used
to cover surfaces (e.g., light handles or x-ray unit
heads) that are otherwise difficult or impossible
to disinfect.
• Disinfectant protocols for impressions,
instruments, prostheses.
18. • The tubes of aspirators and saliva ejectors
should be flushed with sodium hypochlorite,
0.1% regularly.
• Safety from prick from sharp instruments.
• Operating room, chair can be cleaned with
70% alcohol or with 0.5% chlorhexidine in
70% alcohol.
• Vaccination against Hepatitis B, Neisseria
meningitis, Diphtheria, Tuberculosis.

21. OBTAINING MEDICAL HISTORY
FROM PATIENT
• A thorough medical history is extremely
important for patient may not always show
sign of a disease.
• It alerts the clinician to medical problems
that could, in conjunction with dental
treatment, adversely affect the patient.
22. MANDATORY BLOOD/ SALIVA TEST
BEFORE ANY SURGICAL PROCEDURE
• An oral healthcare
professional, must
recognize signs and
symptoms in the patient
because sometimes
patient may shy away or
may lie about its health
history.
23. It is mandatory for the
operator to ask the
patient to get his/her
blood or other
necessary diagnostic
test done for evaluating
any possibility of blood-
borne and other
infectious diseases.
24. DISPOSAL OF WASTE MATERIALS
COLOR CODING WASTE DISPOSAL
RED Catheters, Injections, Syringes, Tubings, Plastic
waste, IV bottles
YELLOW Guaze, Cotton, Bandages, Human tissue, infectious
waste
BLUE Broken glasses, bottles, outdated medicines
BLACK Needles without syringes, blades, sharps, metal
articles.
27. Simple precautions like washing of hands
using surgical soap and/or an antiseptic
hand-wash, drying hands with a single use
disposable paper towel, using protective
clothing and eyewear, maintaining
sterilization protocols, avoiding needle prick
injuries can decrease chances of transient
micro-organisms which are capable of
transmitting disease.
