3. INTRODUCTION
Dr. Greene Vardiman Black (1836-1915)
Black made a
prophetic
statement "The day
is surely coming
and perhaps within
the lifetime of you
young men before
me when we will be
engaged in
practicing
preventive rather
than reparative
dentistry".
5. DEFINITIONS
HEALTH - “a state of complete physical, mental
and social well-being and not merely the absence
of disease or infirmity” (World Health
Organization 1946)
PREVENTIVE DENTISTRY – It is that specialized
branch of dentistry which deals with the
prevention and interpretation of the progress of
all dental and oral diseases, prevention and
limitation of disabilities and provides
rehabilitation.
7. Control of disease
Patient education and motivation
Development of host resistance
Restoration of function
Maintenance of oral health
PRINCIPLES
8. SCOPE
Factors
predisposing to
disease can be
controlled
Factors
encouraging the
advancement of
disease can be
altered
Complication of
disease and
deformity can
be avoided
Factors causing
recurrence of
disease can be
eradicated.
10. PRIMORDIAL PREVENTION
A new concept
Prevention of the emergence or
development of risk factors in countries or
population groups in which they have not
yet appeared
Individual and mass education
11. PRIMARY PREVENTION
Taken prior to the onset of disease which
removes the possibility that the disease will
ever occur (K. Park)
Uses strategies and agents to prevent the
onset of disease, reverse the progress of
disease or arrest the disease process before
secondary treatment becomes necessary.
This level is sometimes thought of as dental
hygiene (Norman Harris)
12. Concept of positive health
Encourages
achievement
and
maintenance
of an
acceptable
level of
health
that will
enable every
individual to
lead a
socially and
economically
healthy life
13. Approaches for Primary Prevention
1Population
(mass)
strategy
The WHO has recommended the following approaches for the primary
prevention of chronic diseases where the risk factors are established:
2 High -risk
strategy
• “Population strategy" is directed at the whole population
irrespective of individual risk levels.
• The population approach is directed towards socio-
economic, behavioral and lifestyle changes
• The high -risk strategy aims to bring preventive care to
individuals at special risk.
• This requires detection of individuals at high risk by the
optimum use of clinical methods.
15. Primary
prevention
Health promotion
Life style and behavioral
changes
Nutritional interventions
Health education
Environmental modifications
Specific protection
Immunization and
seroprophylaxis
Use of specific nutrients or
supplementations
Protection against
occupational hazards
Safety of drugs and foods
Control of environmental
hazards,
16. Goal:
Reduce number of new casesPhase of disease:
• Specific Causal Factors
Typical
activities:
• Remove or reduce source of
the risk
• Educate and make aware of
disease risk
• Include behavioral changes
to reduce exposure
• Improve general health
Target
population: Those who are most likely to
be exposed (high risk) and/or
could increase their resistance
PRIMARY PREVENTION
17. SECONDARY PREVENTION AND EARLY
INTERVENTION
It is defined as “ action which halts (stop)
the progress of a disease at its incipient
stage and prevents complications.”
Reverse the initiation of disease
An outcome of good health can still be
achieved
18. Approaches for Secondary Prevention
Early
diagnosis
and
treatment.
Early diagnosis (e.g. screening tests, and case finding
program)
Treating it before irreversible pathological changes take
place, and reverse communicability of infectious diseases
19. Goal:
• Reduce number of new cases;
• Reduce number of severe cases
Phase of disease:
Early stage of disease
Typical
activities:
• Screening for exposure
and/or disease
• Post-exposure prophylaxis
• Early treatment to reduce
impact of disease/reverse
course
Target
population:
Those who have been exposed to
the disease-causing agent or have
early symptoms of the disease
SECONDARY PREVENTION
20. Tertiary Prevention
All measures available to reduce or limit impairments
and disabilities, minimize suffering caused by existing
departures from good health and to promote the
patients adjustment to irremediable conditions
Disease impairment disability handicap
A.Disability limitation early symptomatic disease
B.Rehabilitation late symptomatic disease
21. IMPAIRMENT
- any loss or abnormality of
physiological, psychological or
anatomical structure or function.
DISABILITY
- any restriction or lack of ability to
perform an activity in the manner or
within the range considered normal
for a human being.
HANDICAPPED
- a disadvantage for a given individual
resulting from an impairment or a
disability, that limits or prevents the
fulfillment of a role that is normal for
that individual
IMPAIRMENT Vs DISABILITY Vs
HANDICAPPED
22. Rehabilitation
The combined and coordinated use of medical, social, educational and vocational measures for
training and retraining the individual to the highest possible level of functional ability.

23. Goal:

complications
Phase of disease:

Typical
activities:
• Treatment tailored to the
patient
• Rehabilitation to promote
recovery
Target
population:
Those who have disease and need
treatment

occur in the interval between health supervision visits that
includes information about daily caretaking specific to that
upcoming interval [1]..”

MAY CAUSE STRESS OR

gums by applying

42. Diet , nutrition and food choices
1
The Parents /
caregivers
should be
intimated
against putting
baby to bed
with a bottle.
2
Children should
be encouraged
to use the cup
as early as
possible (by 1
year of age)
3
Parents should be
educated that the
frequency of
sugar exposures is
more detrimental
to oral health
rather than the
amount of sugar
4
Prolonged bottle
feeding with
sugar containing
drinks and
frequent
between meal
consumption of
sugar containing
snacks or drinks
(juice, formula,
soda) should be
thoroughly
discouraged
5
Acids in
carbonated
beverages can
have a
deleterious
effect on tooth
enamel causing
erosion
6
Dietary analysis
is to be done at
periodic intervals
and healthy
alternatives are
to be suggested
for replacing the
cariogenic foods
43. Non Nutritive Habits
Although the use of pacifiers and digit sucking are
considered normal, habits of sufficient intensity,
duration and frequency can contribute to deleterious
changes in occlusion and facial development. So it
becomes important to discuss the need to wean
from the habits as early as possible (by 3years of
age) [2]. For school aged children and adolescents
patient counseling regarding any existing habits (nail
biting, bruxism, clenching) is appropriate.
44. Sucking Habits
The Parents /
caregivers
should be
intimated
against putting
baby to bed
with a bottle.
1
Sucking is a
natural reflex
which is
present inutero
and is generally
given up by 4 –
5 years of age
2
BUT if it
persists
beyond this
age it may
result in
malocclusions.
3
To break the
habit, child
must be
educated
about the
harmful effects
of thumb
sucking
45. Speech and language
Speech and language are integral components of
child’s early development. Deficiencies and
abnormal delays in speech and language
production should be recognized early and
appropriate referral made to address these
concerns
46. Injury prevention
Facial trauma that results in fractured, displaced or lost tooth
can have significant negative, functional, esthetic and
psychological effects on children. Greatest incidence of
trauma to the primary dentition occurs at 2 – 3 years of age
and most common injuries to the permanent dentition occur
secondary to falls, traffic accidents and sports
47. Fluoride needs
Since fluoride contributes to the prevention, inhibition and
reversal of caries, the family’s source of drinking water
(bottled versus tap water, filtered or non-filtered, water
treated by reverse osmosis) is to be assessed for the content
of fluoride. Supplements of fluoride or topical fluoride
applications may be advocated depending upon the needs of
the patient.
