LYMPH NODE EXAMINATION
THE LYMPHATIC SYSTEM
·
Lymphatic
system is a closed system of channels called lymph channels or lymph vessels.
It is the one way system and the lymph flows through this from tissue system
towards blood.
Lymph
·
Lymph
is a transudate from blood & contains the same proteins as in plasma but in
smaller amounts.
·
It
mainly consists of lymphocytes.
Lymphatic vessels
·
Lymphatic
vessel includes lymph capillaries & larger lymph vessels.
Lymph capillaries are similar to blood capillaries,
but adapted to have much greater permeability.
they are found in most tissues of the body, except avascular tissues
like cornea, hair, nails etc.
Larger lymph vessels
·
They
have structure similar to that of veins.
·
Lymph
capillaries join together to form large lymph vessels.
·
THORACIC
DUCT is the largest lymph vessel in the body.
Lymph nodes
·
They
are bean shaped organs found in clusters along the lymphatic channels of the
body.
·
They
are mainly composed of lymphoid tissue.
Structure of
lymph node
·
Lymph
node consists of a connective tissue framework, with numerous lymphocytes and
other cells fill the interstices of the network.
·
Lymph
node is surrounded by a capsule made of collagen fibres. Numerous septa run
into the node from the capsule and divide it into lobules.

Exogenous Pigmentation
For Ppt: http://download1639.mediafire.com/xw0v9gozxglg/jjhu5stdwcgaw9a/Exogenous+Pigmentation.pptx
For word file : http://download816.mediafire.com/614nebzitxtg/7rahnemt5brhtj5/Exogenous+Pigmentation.docx
CONTENTS
INTRODUCTION
The
systemic administration of various drugs and chemicals frequently evokes an
oral and body reaction which is not on the basis of an allergy or sensitivity.
The reaction is often a part of a generalized epidermal reaction, but other
times it occurs as a specific phenomenon apparently due to the anatomical
peculiarities of the oral cavity
DEFINITION
Pigmentation which arises as a result
of introduction of metals or drugs into the body via mucous membrane,
intestinal tract and skin.
CLASSIFICATION
1.
ACCIDENTAL PIGMENTATIION
: Accidental implantation of material in
the gingival tissue.
2.
IATROGENIC PIGMENTATION : Due
to dental procedure
3.
HEAVY METAL PIGMENTATION
: Due to ingestion of metals
like bismuth,
lead , mercury in the body.

INTRODUCTION TO ORAL CANCER
TUMOR
— By definition is an abnormal mass of tissue,
growth of which exceeds and is
uncoordinated with that of normal
tissues and persists in the same excessive manner, after the cessation of the stimuli that evokes the
changes.
— Tumor can either be benign &
malignant.
— Benign tumors are NOT CANCER……..
— Benign tumors are rarely
life-threatening.
— Generally, benign tumors can be
removed, and they usually do not grow back.
— do not invade the tissues around them. and do not spread to other parts of the
body. Malignant tumors may be life-threatening

Viral Infection in Oral Cavity
INTRODUCTION
Virus is a Latin word which means venom or poison. The size of the viruses
varies in millimicrons.
It
consist of central core of DNA or RNA.Virally infected cells produce the same type of
nucleic acid so susceptibility of cells infection may be increased. Viruses cause
certain infectious diseases and produce long-lasting immunity against
reinfection by the same virus.
In addition , there are many neoplasm can be caused
due to the viral infection. The classification of virus is difficult because of
size of viruses and their incompletely understood metabolic systems. However,
their classification based on biologic, chemical and physical properties of the
animal viruses, separating them into groups according to the type of nucleic
acid, and the size, shape and substructure of particle has been undertaken by
the International Committee on Nomenclature of Viruses of the International
Association of Microbiological Societies.

Caries Activity Test
FOR word file : http://www.mediafire.com/download/dz4rlj32xfkd0od/pedo+ameen.docx
CONTENT
DENTAL
CARIES:
It is an irreversible progressive disease of multifactorial nature
affecting the calcified tissues of the teeth characterized by
demineralization of inorganic portion
& destruction of organic portion of the tooth.
CARIES
ACTIVITY:
Caries activity is a measure of speed of
progression of a carious lesion.
CARIES
SUSCEPTIBILITY:
Refers to the inherent tendency of the host & the target tissue
, the tooth to be affected by the
carious process .
Caries
activity test facilitates:
1.Need & extent of personalized preventive measures.
2.Serves as an index of success of the therapeutic measures.
3.Motivates & monitors the effectiveness of education programs relating
to dietary & oral hygiene procedures.
4.Manages the progress of restorative procedures.
5.
Identify
high risk groups & individuals.

INTRODUCTION
Dental caries is the most prevalent
chronic disease affecting the human race. In many ways it can be considered a disease of modern
times as the occurrence of caries seems to be much higher in the last few generations.
It is said that once it occurs the scars persists throughout life even though
the lesion is treated.
It affects
persons of both sexes, in all races, all socioeconomic strata and in every age
group, though some people may be more prone to it than others. Systemic
complications such as, subacute bacterial endocarditis have also been associated with dental
caries.
Therefore
it is mandatory for the clinician to understand the magnitude of this problem
and the risk factors in the community to plan suitable preventive measures.
The word CARIES is derived from the Latin
word meaning rot or decay .
DEFINITION OF CARIES
DENTAL CARIES is an irreversible
microbial disease affecting the hard tissues of the tooth causing
demineralization of inorganic portion and destruction of organic portion which
further leads to cavitations
THEORIES
OF DENTAL CARIES
Many theories have evolved
through years of investigation and observation for etiology of caries
