many types of cancers develop in the oral and maxillofacial region. squamous cell carcinoma is the most common cancer and constitutes over 90 percent of these tumors. malignant transformation is a genetic process, which later makes a phenotyping change at the cellular level. some cancers such as oral squamous cell carcinomas (osccs) develop from pre-malignant lesions and conditions. despite adv...

BACKGROUND Normal and cancerous tissues have distinct auto-fluorescence properties because of differences in their biophysical and biochemical agents. Scientific evidences related to diagnostic fluorescence imaging for detection of oral precancerous and cancerous lesions are very limited. OBJECTIVES The aim of this study was to find out potential relationships between serum, salivary and tiss...

BACKGROUND Previous studies found that topical photodynamic therapy (PDT) is very effective for human oral precancerous lesions. METHODS This study evaluated whether topical photosan-mediated PDT (topical photosan-PDT), using a 640-nm light-emitting diode (LED) light, is an effective treatment modality for hamster buccal pouch precancerous lesions. Fourteen 7,12-dimethylbenz(a)anthracene (DMB...
