 Celiac disease CD has been reported to increase the risk of oral lesions. More recently, it has been reported that a consistent percentage of the general population consider themselves to be suffering from problems caused by wheat andor gluten ingestion, even though they do not have CD or wheat allergy. This clinical condition has been named Non-Celiac Gluten Sensitivity NCGS. In a previous paper the investigators suggested the term Non-Celiac Wheat Sensitivity NCWS, since it is not known what component of wheat causes the symptoms in NCGS patients, and the investigators also showed that these patients had a high frequency of coexistent multiple food hypersensitivity. That previous study also showed a percentage of NCWS patients had weight loss and anemia: whether these depended on the intestinal malabsorption or not remains unclear. As yet no data are available on the presence and prevalence of oral lesions in NCWS patients. The aims of the present study is: 1 to investigate the presence and prevalence of oral lesions in NCWS patient and 2 to search for a possible correlation between oral lesions and other clinical characteristics of NCWS patients.
