The document discusses the intraoral examination process and various diagnostic techniques used in oral health, such as inspection, palpation, percussion, probing, auscultation, and evaluation of odors. It highlights the importance of proper diagnosis to inform treatment plans and improve patient outcomes. The document also includes a list of specific oral conditions, lesions, and their associated locations in the mouth.

4. 5 Sensations
 See
 Hear
 Smell
 Feel
 Taste
(I don’t think we taste our patients, Do we?)

5. See: Inspection
 It’s the art of detecting any unusual
changes in the oral cavities, as its
based on vision a light source is of
high need.
 We can see :
Color changes. “pigmentation or
caries”
Tooth Fracture.
And Different Lesions.
Eg: Erosion.

6. Feel: Palpation
 This depends on our sense of touch to
feel any abnormalities and to
diffrenitte it from the normal.
 The types as we all know are
◦ Bidigtal P.
◦ Bimanual P.
◦ Bilateral P.
 We can detect the different
consistency, temperature, Mobility, in
duration…etc

7. Feel: Percussion
 We examine the this by striking an
object on the tooth and evaluate the
produced sound.
 This technique also helps in grading
the tooth mobility

8. Probing
 This is critically important technique as
it can help detect caries and any
periodontal dieses

9. Hear: Ausculation
 Depends on the fact we listen to the
normal sounds produced by the
patient
◦ Wheezing = Respiratory dieses
◦ TMJ clicking= TMJ disorder

10. Smell: Odor
 Just by smelling the patient oral odor,
we can help in the differential
diagnosis.
 Acetone odor= Uncontrolled DM
 Foul odor = ANUG

11. Functional Evaluation
 Simple to evaluate its function:
 E.g. Salvia flow from the glands. Pulp
testing and occulasal relationship are
just a few of the different methods of
evaluation.

46. Remember…
 What ever your Techniques is, it is as
good as how you diagnosed your
case.
 To Know to diagnosis is just half the
way, a true doctor must use his
diagnosis capability as tools to pave
the way to identify the problem or
Dieses .
 With the proper diagnosis, and
identification the proper action and
treatment plan can be done, and the
prognosis and be seen easily
