Amino Acid profile in oral submucous fibrosis: a high performance liquid chromatography (HPLC) study.

Background: Collagen is a significant structural protein, the integrity of which is essential to be maintained for proper homeostasis. Oral submucous fibrosis (OSMF), being a collagen metabolic disorder, may be subject to changes in amino acid profiling.

Aim: The present study was attempted to evaluate the amino acid profile to assess its feasibility as a biological marker in OSMF.
