A NOMOGRAM TO PREDICT THE MALIGNANT TRANSFORMATION RISK OF OPMDS USING CHAIR SIDE DIAGNOSTIC AIDS AND HISTOPATHOLOGICAL EXAMINATION Authors: Swathi KV* and Maragathavalli G
ABSTRACT
A nomogram is a graphical calculating device mainly used for the graphical computation of a
mathematical function. It is basically a diagram consisting of scales representing the
relationship between three or more variable quantities. The value of an unknown variable can
be found by simple geometrical construction, by drawing a straight line intersecting the other
scales at appropriate values. Oral Potentially Malignant Disorders (PMD) includes a variety
of lesions and conditions characterised by an increased risk of malignant transformation to
oral squamous cell carcinoma. A biopsy (histopathological examination) is considered to be
the gold standard for the definitive diagnosis of an OPMD and its malignant progression.
There are various chair side diagnostic aids like vital staining, light based detection systems
and other non invasive diagnostic aids like exfoliative cytology like brush biopsy which can
serve as adjuvants for diagnosis of these disorders and for proceeding with treatment
planning such as need for biopsy for the definitive diagnosis. There are also various
molecular and genetic markers which can be used in the diagnosis of OPMDs and oral
cancer. This review highlights about various OPMDs, chair side diagnostic tools and aims to
device a nomogram to predict the risk of malignant transformation of OPMDs using chair
side diagnostic aids and histopathological examination.
