The aim of this study is to detect P53 expression in clinically normal oral mucosa of cigarette smokers, simultaneous cigarette and cannabis smokers and non-smokers as a surrogate marker for field cancerization.
Roles and Responsibilities:
1- Intervention: A.K. will collect specimens from cigarette smokers and simultaneous cigarette and cannabis smokers. then the expression of p53 as a marker for field cancerization will be investigated in formaline fixed paraffine embedded specimens of mucosal biopsies obtained from the oral mucosa of both groups.
