Summary

investigating the level of malondialdehyde (MDA) \& nitric oxide (NO) in saliva in oral premalignant and malignant lesions in order to determine their diagnostic value for the malignant and potentially malignant lesions.

Detailed description

Being a detrimental disease, cancer development is a very complicated process that requires many sequential steps and depends on a various number of genetic alterations and factors(1). Among these factors are the free radicals which are derived either from endogenous or exogenous sources (5). Free radicals result in an oxidative stress of the affected cells generating a body imbalance between oxidants and antioxidants (6). In this regard, saliva has been currently used to assess this possible oxidative imbalance through various salivary biomarkers including nitric oxide (NO) and malondialdehyde (MDA). Saliva could be used as a very interesting rich medium, known for its role in diagnosis, prognosis and treatment that has become more prominent in oral diseases (6). Nitric oxide (NO) is an intercellular messenger molecule having many important biological functions. The levels of nitric oxide in salivary secretions could be used to monitor the severity of many underlying disease processes. Moreover, malondialdehyde (MDA) has been the most frequently used biomarker of oxidative stress in many pathological conditions such as cancer. It resulted from reactive oxygen species lipid degradation and induced toxic stress in affected cells, making both biomarkers a point of focus in monitoring clinical progress of suspected lesions
