This document provides an introduction to public health, including definitions of key terms, the history and evolution of public health, and the core functions and approaches of public health. It defines public health as organized community efforts to prevent disease and promote health. Key points include:
- Public health aims to provide maximum health benefits to the largest number of people through community-wide prevention efforts, in contrast to medicine which focuses on treating individuals.
- Major milestones in the history of public health include advances in sanitation and hygiene in ancient Greece and Rome, the germ theory of disease in the 19th century, and the establishment of public health systems and agencies in the 19th-20th centuries.

Olfactory Membrane:
Located in the superior part of the nasal cavity.
Medially: Folds downward along the superior septum.
Laterally: Folds over the superior turbinate and upper surface of the middle turbinate.
Total surface area: 5-10 square centimeters.
Olfactory Mucosa:
Olfactory Cells: Bipolar nerve cells derived from the CNS (100 million), with 4-25 olfactory cilia per cell.
Sustentacular Cells: Produce mucus and maintain ionic and molecular environment.
Basal Cells: Replace worn-out olfactory cells with an average lifespan of 1-2 months.
Bowman’s Gland: Secretes mucus.
Stimulation of Olfactory Cells:
Odorant dissolves in mucus and attaches to receptors on olfactory cilia.
Involves a cascade effect through G-proteins and second messengers, leading to depolarization and action potential generation in the olfactory nerve.
Quality of a Good Odorant:
Small (3-20 Carbon atoms), volatile, water-soluble, and lipid-soluble.
Facilitated by odorant-binding proteins in mucus.
Membrane Potential and Action Potential:
Resting membrane potential: -55mV.

Adaptation Towards the Sense of Smell:
Rapid adaptation within the first second, with further slow adaptation.
Psychological adaptation greater than receptor adaptation, involving feedback inhibition from the central nervous system.
Primary Sensations of Smell:
Camphoraceous, Musky, Floral, Pepperminty, Ethereal, Pungent, Putrid.
Odor Detection Threshold:
Examples: Hydrogen sulfide (0.0005 ppm), Methyl-mercaptan (0.002 ppm).
Some toxic substances are odorless at lethal concentrations.
Characteristics of Smell:
Odor blindness for single substances due to lack of appropriate receptor protein.
Behavioral and emotional influences of smell.
Transmission of Olfactory Signals:
From olfactory cells to glomeruli in the olfactory bulb, involving lateral inhibition.
Primitive, less old, and new olfactory systems with different path
Anti ulcer drugs and their Advance pharmacology ||
Anti-ulcer drugs are medications used to prevent and treat ulcers in the stomach and upper part of the small intestine (duodenal ulcers). These ulcers are often caused by an imbalance between stomach acid and the mucosal lining, which protects the stomach lining.
||Scope: Overview of various classes of anti-ulcer drugs, their mechanisms of action, indications, side effects, and clinical considerations.

3. WHAT IS HEALTH?
Health is a state of complete physical, mental and social well-being and not
merely the absence of disease or infirmity.
-World Health Organization(WHO)
4. WHAT IS PUBLIC HEALTH?
Public Health is the “science and art of preventing
disease, prolonging life, and promoting health and
efficiency through organized community efforts”.
— CEA Winslow (1920)
5. WHAT IS DENTAL PUBLIC HEALTH?
Dental public health is “the science and art of preventing and controlling dental
diseases and promoting dental health through organized community efforts. It is
that form of dental practice that serves the community as a patient rather than the
individual. It is concerned with the dental education of the public, with applied
dental research, and with the administration of group dental care programs as well
as the prevention and control of dental diseases on a community basis”.
-American Board of Dental Public Health (ABDPH)
By adapting Winslow’s definition (1976)

17. UPSTREAM VS DOWNSTREAM THINKING
the level of interventions to
positively impact on public health.
‘Upstream’ and
‘Downstream’
UPSTREAM DOWNSTREAM
• At the population (upstream)
level, public health works to
address the determinants of
health which relate to the
conditions under which
people live .
• At the individual (downstream)
level, people may be treated
for a condition using targeted
strategies (McKinlay, 1979).
• Interventions has a complex
contemporary discussion of
attribution of effect.
• Interventions are considered to
be futile and short term.
(McQueen and De Salazar,
2011).
The two terms originate from the analogy of busily dragging
drowning people from a flooded river (downstream) without
going (upstream) to discover the reason as to why they were
falling or being pushed into the river (McKinlay, 1979).
19. THE PUBLIC HEALTH SYSTEM
Public health system is defined as “all public, private,
and voluntary entities that contribute to the delivery of
essential public health services within a jurisdiction.”
It includes:
•Public health agencies at state and local levels
•Healthcare providers
•Public safety agencies
•Human service and charity organizations
•Education and youth development organizations
•Recreation and arts-related organizations
•Economic and philanthropic organizations
•Environmental agencies and organizations

21. A PUBLIC HEALTH APPROACH-- CHOLERA
Cholera, a fatal intestinal disease, was rampant during the early 1800s
in London, causing death to tens of thousands of people in the area.
Cholera was commonly thought to be caused by bad air from rotting
organic matter.
22. JOHN SNOW, PHYSICIAN
John Snow is best known for his work tracing the source of the cholera outbreak and he
is considered the Father of Modern Epidemiology.
He believed that the illness was spreading by way of a contaminated water supply
because sewage was routinely dumped into the Thames River and cesspools near town
wells.
23. Epidemiology — What is the Problem?
Cluster of Cholera Cases, London — 1854
Image: The Geographical Journal
Reverend Henry Whitehead
Snow was assisted by a local
clergyman, Reverend Henry
Whitehead, in tracking down and
interviewing cholera victims and
their families and geographically
mapping the outbreak
24. Cluster of Cholera Cases and Pump Site Locations
Risk Factor Identification — What Is the Cause?
Image: The Geographical Journal
Snow believed that water was
a potential cholera source,
based on his previous works
This observation prompted Snow to
further research the distribution of
water pumps in London.
Through his research, Snow
identified and concluded that
drawing water from the Broad
Street pump was a primary risk
factor for becoming ill with cholera.
The map reveals that the
largest number of cholera
cases occurred in areas near
water pumps.
25. Intervention Evaluation — What Works?
Through continuous research, Snow understood
what interventions were required to
• stop exposure to the contaminated water
supply on a larger scale, and
• stop exposure to the entire supply of
contaminated water in the area
26. Implementation — How Do You Do It?
John Snow’s research convinced the
British government that the source of
cholera was water contaminated with
sewage, which resulted in the
implementation of policies and laws for
water sanitation.
Snow implemented the Intervention by
taking out the handle off the broad
street pump, and the cholera outbreak
subsided.
27. THREE CORE FUNCTIONS OF PUBLIC HEALTH
ASSESSMENT
POLICY DEVELOPMENT
ASSURANCE
Ensure provision of services to those in need
Promote the use of a scientific knowledge
base in policy and decision making
Systematically collect, analyze, and make available
information on healthy communities.

32. PRINCIPLES OF PUBLIC HEALTH
Five key principles:
1. A broad and positive health
concept;
2. Participation and involvement;
3. Action and action competence;
4. A settings perspective and
5. Equity in health
KEY ELEMANTS OF PUBLIC HEALTH
HEALTH PROTECTION
HEALTH PROMOTION
1. planning and preparedness;
2. prevention and early detection;
3. investigation and control; and
4. wider public health
management and leadership
(including communication to
professionals and the public).

33. Activating and mobilizing emergency plans
Serving as communicable disease experts. During disease
outbreaks, epidemiological experts conduct investigations,
contact tracing, monitor suspected cases, enforce isolation and
quarantine protocols and set up mass clinics;
Assisting and connecting vulnerable individuals to resources like
housing, nutritious meals, utilities and health or mental health
services;
Supporting community partners and working with the State
Department of Health and the Centers for Disease Control and
Prevention.
Upholding state and local laws. Public Health law grants authority
to local health officials to respond to disease threats and they are
legally responsible for the control of communicable diseases;
Keeping community members informed by answering questions,
providing up-to date information and the local community
impact, and recommendations for how to protect your family
from exposure.
