[Importance of oral signs in the diagnosis of atypical forms of celiac disease].

The dramatic improvement in knowledge concerning celiac disease (CD) has disclosed the pattern of the associated clinical manifestations and the often atypical or silent presentation of this disease, which makes clinical diagnosis difficult. Also oral manifestations, mostly recurrent apthous stomatitis (RAS) and dental enamel hypoplasia, are atypical signs of CD. Our opinion about the possibility of performing mass-screening to reveal atypical or silent CD is in agreement whit who is asserting that a sistematical case-finding is, at present, the most suitable epidemiological approach. So, we think that patients affected by RAS, or dental enamel hypoplasia, should be considered, even in the absence of any gastrointestinal symptom, at-risk subjects, and should therefore undergo diagnostic procedure for CD.
