all medical and dental history as well as additional
tests that we can use for the evaluation of a patient
in particular. That helps us in a differential clinical
diagnosis and to orientate the definitive diagnosis
in FNAB.
In situations where a malignant neoplasm is
suspected, in front of a benign or inconclusive
diagnostic in FNAB, a biopsy should be performed,
since it is a gold standard for the final and definitive
diagnosis of lesions in general.
The experience of the pathologist to see slides
of FNAB is essential for its diagnosis to be the most
accurate, as well as familiarity with a particular
technique of staining, helping thus considerably in
the final diagnosis of the material collected by FNAB.
Even though it is not so commonly used in FNAB,
H&E stain should be considered by the pathologist at
the time of viewing the slides, because it preserves
similarities to histological cell structure.
We also encourage further studies with the use
of ancillary techniques to refine the diagnosis, thus
increasing the acuracy of the technique.
Even with all the limitations found in this
study, the use of FNAB in the oral cavity and the
head and neck region, under the legal limits of
the dental practice should not be discouraged and
new studies evaluating how this diagnostic tool is
important, saved their proper indications, should
be performed.
