Coeliac disease is common worldwide. It is estimated to occur in about 1% of the US population [1]. While the rate of diagnosis is increasing [2], by far the majority of those with coeliac disease are currently undiagnosed. There are multiple reasons for the low rate of diagnosis; these include lack of awareness of the more subtle presentations of coeliac disease [3], atypical presentations (non-diarrhoeal) that are in fact more common [4], diagnostic delay, alternative diagnosis and attribution of symptoms to other diagnoses [5,6] and lack of knowledge in the primary care setting [7]. There is a broad spectrum of clinical manifestations of coeliac disease in childhood and adults. Infants may present with diarrhoea and failure to thrive, while older children with short stature, anaemia, neurological problems or gastrointestinal complaints [3]. Adults may be asymptomatic, only those at risk groups are detected by screening programmes [8]. Those detected in a population-based screening programme, who had considered themselves well, had mild anaemia, reduced bone density, low cholesterol level and a trend toward lower cardiovascular events [9]. The most frequent presentation, however, is still diarrhoea, with and without a malabsorption syndrome [4]. Other presentations include osteoporosis [10], irritable bowel syndrome [11], iron deficiency anaemia [12], incidental recognition of the signs of villous atrophy in the duodenum at endoscopy performed for reflux type symptoms [13] and neurological presentations [14,15]. At the other extreme are those that present with a severe malabsorption syndrome, small intestinal adenocarcinoma [16], refractory sprue or an enteropathy associated T-cell lymphoma [17]. The reason for this tremendously variable phenotypic presentation of coeliac disease is unclear [18]. ∗ Corresponding author at: Celiac Disease Center, Columbia University Medical Center, 161b Fort Washington Avenue, New York, NY 10032, USA.

Screening studies from the United Kingdom have demonstrated the prevalence of the disease to be 1% of both sevenyear-old children and adults, suggesting that the disease starts in childhood and is present in adulthood when it may be manifested [9,19]. Along these lines, Finizio et al. (in this issue) of the journal describe the ‘coeliac face’ [20]. They describe disproportionately large foreheads in people with coeliac disease diagnosed in adulthood and in those diagnosed in childhood, but are not adherent to the diet. Those diagnosed in childhood who were adherent to the strict gluten-free diet did not exhibit this sign. This sign is attributed to the failure in the growth of the bones of the middle third of the face, bones that make up part of the viscerocranium. This indicates a process either nutritional or immunological affecting growth rates of specific bones at a vulnerable period of growth. Dental enamel defects are another example of a manifestation of a process occurring during a specific time period of teeth growth before age of seven years [21]. These changes in enamel, most frequently identified as symmetrical and chronologically occurring white or yellow opacities with or without horizontal lines often with the glaze of the enamel altered, mainly affect the incisors and first molars. Recognition of these defects can lead to the diagnosis of coeliac disease [22]. Gastroenterologists are generally not aware that the appearance of the teeth provide a window to health in childhood. Similarly, it appears that facial proportions reflect similar processes. It remains to be seen whether the large forehead sign of the coeliac face can be identified in populations apart from those of Italy, studied by Dr. Finizio and colleagues. However, they need to be congratulated on their translation of a clinical observation into a well conducted clinical research finding. The other message is that physicians do not see a particular sign until it is demonstrated as a sign. We now examine the teeth of patients seen in our gastroenterology and dental practices for dental
