Oral Sphere: Salivary Markers and Food. A Prospective Study in Children Expressing Oral Disorders (ORALISENS)
In Human, the oral sphere is the first and main place where sensory stimuli are received and perceived. The phenomena occuring during food breakdown and sensory perception are complex and in this system saliva plays a major role.
In the neonatal period, severe digestive diseases require the cessation of all oral feeding and the use of enteral or parenteral nutrition for prolonged periods to ensure the growth and development of children while their disease is active. The early stages of sensory oral exposures and their consequences on the development of eating habits of these children are poorly documented. It is likely that the process of acquisition of preferences and eating habits is atypical because of a "bypass" of the oral sphere during the early stages of feeding. Thus, if not orally fed, children do not get exposed to a wide variety of tastes and textures in the first year of life, which may impact on their oral acceptance at a later age. These oral disorders (OD) are expressed by a refusal to eat, a heightened gag reflex, a refusal of certain consistencies and difficulties in chewing and swallowing. Few data are available on food typically accepted by these children.
Finally, oral sensory phenotypes of OD children (gustatory sensitivity ...) have not been described yet. It is likely that they may differ significantly from those of healthy (NOD).
In this context, a population of OD children is particularly interesting for studying the effects of the absence of these learning stages and their consequences in the development of sensory perception and eating habits.
The investigators formulate the hypothesis that the lack of exposure to a standard oral diet would modify the development of their "oro-sensory systems" including saliva.
Studying such a population is a great opportunity to assess the influence of non oral food exposures and diet on saliva characteristics.
Saliva has recently received attention as a potential easy to collect source of biomarkers in several conditions excluding OD.
The potential impact of OD on salivary composition has never been studied. Several studies linking saliva and perception or preferences have been conducted in the UMR CSGA (Unité Mixte de Recherche du Centre des Sciences du Goût et de l'Alimentation). They have already contributed to highlight the great inter-individual variability for a number of saliva markers and a change in saliva protein profiles in response to taste stimulation They also underlined the remarkable intra-stability for saliva flow and composition during a one year study.
This study intends to prove the concept that it is relevant to relate saliva characteristics to food intake behaviour or food habits The first hypothesis to be tested in this study is that salivary profiles (biological signatures) can discriminate two groups of children differing by their orality.
The second hypothesis to be tested is that these specific biological biological signatures may be correlated to certain food habits associated or not with oral disorders.
