A prospective study was carried out to assess the role of salivary NO levels in etiopathogenesis of OLP, and to further correlate the levels of salivary NO levels with mast cell (MC) count. The study also evaluated the role of psychological factors in etiopathogenesis of OLP using DAS (Depression anxiety and stress) Scale. The sections were stained with toludine blue. The number and types of mast cells were assessed, and then correlated with the increased salivary NO level further reviewing the role of mast cells in the etiopathogenesis of OLP.The following conclusions can be proposed: Free...

This book reviews the basic chemistry of free radical formation in the body, the consequences of free radical induced tissue damage, and the function of antioxidant defence systems, with particular reference to their role in oral disease and oral cancer.As part of a healthy lifestyle and a well-balanced, wholesome diet, antioxidant supplementation is now being recognized as an important means of improving free radical protection. Additional work aimed at investigating the source, function, and regulation of antioxidants may help determine new therapeutic strategies based upon these apparent...

Metastasis is an extraordinarily complex process that remains to be a major problem in the management of cancer. Metastasis, which is a process in which primary tumors disseminate to secondary organs, is a major cause of cancer mortality. Metastatic tumors to the head and neck region are generally rare and they account for less than 1% of the metastatic tumors occurring in the body. Metastasis to soft tissue of the oral cavity is much rarer than jaw bones, because of rarity, metastatic tumors in the oral region are challenging for diagnosis. Although the oral cavity is not a common site for...
