Objective
information that can be measured or perceived by the investigating clinician; i.e. signs

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
