6. Provisional diagnosis
Diagnosis arrived at after
history taking and clinical
examination but before any
investigations.
Preliminary educated
assumption or guess as to the
nature or status of the
condition prior to the analysis
7. Differential diagnosis
Process of identifying a
particular disease process by
differentiating it from all other
pathologic processes that may
have similar signs and
symptoms or clinical course
8. Final Diagnosis
Diagnosis arrived after all the
data (History, clinical
examination and investigations )
has been collected, analyzed
and subjected to logical thought.
9. Prognosis
Prediction of the course,
duration and termination of a
disease and the likelihood of its
response to treatment
11. Laboratory Investigations
Extension of physical
examination in which tissue,
blood,urine, saliva or any other
specimen is obtained from the
patients body and subjected to
microscopic, biochemical,
microbiological or immunological
examination
15. Percussion
Technique of striking the
tissues with the fingers or an
instrument so that the
examiner may listen to the
resulting sounds or note the
response of the patient to
such action
23. Exudate
It is the edema fluid
produced by certain
inflammatory reactions having
a higher specific gravity
(1.020 or higher) and a
higher protein content (1-6
gm/dl)
24. Transudate
It is the edema fluid produced
by certain noninflammatory
conditions having a low
specific gravity and a low
protein content
42. White lesion
•
Abnormal area of oral mucosa
which appears whiter than the
surrounding tissue and is usually
slightly raised, roughened or of a
different texture than the adjacent
normal tissue.
47. Hamartoma
• Tumour
like malformation
characterized by the presence of
particular histologic tissues in
improper proportions or distribution
with a prominent excess of one type
of tissue.
Eg: Haemangioma
48. Teratoma
•
True neoplasm made up of a number
of different types of tissues that are
not native to the area in which the
tumour occurs.
50. Neoplasm
•
Abnormal mass of tissue, the
growth of which exceeds and is
uncoordinated with that of the
normal tissue and persists in the
same excessive manner even after
the cessation of the stimulus that
evoked the change
51. Hypertrophy
•
Increase in the size of an organ or
tissue due to an increase in the
size of the cells
Example: Masseteric hypertrophy
52. Hyperplasia
•
Increase in the size of an organ or
tissue due to an increase in the
number of the cells
Example: Gingival hyperplasia
73. Metaplasis
• Is the reversible replacement of one
differentiated cell type with another mature
differentiated cell type
74. Metastasis
• Metastasis is a complex process that
involves the spread of a tumor or cancer to
distant parts of the body from its original
site
75. Mutation
• A relatively permanent change in
hereditary material involving either
a physical change in chromosome
relations or a biochemical change
in the codons that make up genes
