Abstract

Abstract: Dry mouth has a profound effect on the oral environment and alters susceptibility to oral disease. It is well-recognized in adults but affected children may not report symptoms even when severe oral dryness is present, potentially leading to late diagnosis and missed opportunities to prevent caries and other adverse sequelae. This article describes the causes and clinical signs of salivary hypofunction in children and young people and documents some associated emotional and social impacts on patients and their families. It is illustrated by four cases where the underlying diagnoses were 22q11 micro-deletion syndrome, congenital salivary gland aplasia, sarcoidosis and medication-induced.

CPD/Clinical Relevance: An awareness of the possible presentations, underlying causes and impacts of dry mouth in children and young people will enable vigilant dental practitioners to diagnose the problem at an earlier stage, so that appropriate enhanced preventive care and additional support can be offered promptly.

Article

The problem of dry mouth is well-recognized in adults but receives relatively little attention in the dental literature when it presents in children and young people.1 Prevalence has been shown to have a wide range in the population as a whole (0.9% to 46%) with a shortage of population-based studies carried out in younger age groups.2 There is a wide scope of potential underlying causes3,4 across all age groups (Table 1). An important difference, however, is that children do not always report xerostomia, the subjective feeling of oral dryness, even when salivary hypofunction is found to be severe.5 It is suggested that children with congenital salivary hypofunction do not readily perceive a problem compared to individuals whose oral environment alters in later life.6,7
