title: Detection of potentially malignant lesions and squamous cell carcinomas in consultation of surgical denstitry.
abstract: Squamous cell carcinoma can occur on a apparently healthy mucosa or be preceded by lesions Chronic called potentially malignant, often asymptomatic, rarely showing the reason for consultation of patients, particularly in our Moroccan background which is  characterized by a care difficulty of access and the absence of priority to oral health.
  
  
  OBJECTIVE
  To assess the prevalence of diseases potentially and malignant squamous cell carcinomas, and the role of certain risk factors in the onset of these lesions.
  
  
  METHODS
  In the consultant population center Dental Consultation and Treatment of Casablanca CHU, we conducted a descriptive survey with 306 patients seen for different patterns between May and July 2010.
  
  
  RESULTS
  64.7% of the population had a defective hygiene. In addition, for 40 patients having an oral lesion mucosa, only 16 viewed for these lesions; the others were diagnosed incidentally. Five of these lesions were carcinomas, 32 white lesions of leukoplakia and 256 lichen planus. 7.2% of the population was smoking which nearly half were alcolo-smoking. The most risk factor according to this study significant is the alcohol and tobacco intoxication.
  
  
  CONCLUSIONS
  This study confirms the importance of early screening of  symptomatic chronic lesions potentially malignant as well as squamous cell carcinoma which allows to improve prognosis.
