Objective
|
information that can be measured or perceived by the investigating clinician; i.e. signs
e.g. size,color, duration, consistency, surface contour, etc. |
|
Subjective
|
Patient's own interpretation of a clinical circumstance;
i.e. sympotms Relies on neurologic and psychologic experiences e. g. patient awarenes of presence of a lesion, pain intensity, pain quality (stabbing, burning, shocking, etc..), temperature, etc. |
|
Inspection
|
visual observation
|
|
Diascopy
|
compressing tissue with a glass slide (perio probe) to determine vascular nature of a lesion
|
|
Palpation
|
feel and press a lesion to yield information about texture, consistency, temperature and function
|
|
Probing
|
- palpation with an instrument
- instruments incl. perio probe, caries explorer, needle tip, etc. |
|
Percussion
|
striking tissues with fingers or an instrument and listening to resulting pressure changes in the tissues
|
|
Aspiration
|
withdrawl of fluids from a body cavity
|
|
Auscultation
|
listening for sounds within the body
|
|
Diagnostic Lab Tests for Oral Lesions
|
- Biopsy
- Immunofluorescence - Exfoliative Cytology |
|
Three types of biopsy
|
- Incisional
- Excisional - Aspirational |
|
Biopsy indications
|
- Lesion with >/= 14 day duration
- Unusual location - Unusual appearance - Suspicion of neoplasia - Any excised tissue - Confirm diagnosis of systemic disease |
|
Suspicion of neoplasia
|
- Persistent ulceration
- Pesistent erythroplasia - Induration - Fixation - Chronicity - Lymphadenophathy - Unexplained leukoplakia |
|
Indications for oral exfoliative cytology
|
- Innocuous lesion
- Suspicious lesion with negative biopsy - Patient refuses biopsy - Follow-up of treated malignancy - Lesion where patient is a poor risk for surgery |
|
Contraindication for oral exfoliate cytology
|
- Keratotic or crusty mucosa
- Red, vesicular or velvety mucosa - Submucosal swelling with normal mucosa - Suspicion of malignancy |
|
Broom sweep - exfoliative cytology
|
only surface cells captured
limited to superficial cells |
|
Brush biopsy
|
complete transepithelial tissue sample
|
|
Culture and sensitivity testing / Indications
|
- Life threatening infection
- Unsuccessful previous antibiotic therapy - Immunosuppressed patient |
|
Reasons for limited use of culture and sensitivity testing in dentistry
|
- Difficult for anaerobic conditions
- Turnover time too long; best to attempt trial therapies of certain antibiotics as results may occur quicker than the time interval of the test |
