Abstract

Neurofibromatosis type 1 (NF1) is one of the most common genetic diseases in humans and has widely variable expressivity. Oral manifestations are common, but there are no studies that investigated functional alterations in salivary glands in NF1. Our aim was to evaluate the salivary flow rate in NF1 individuals, comparing to a control group, and to investigate the possible causes and some consequences of salivary gland alteration. This is a case-control study that evaluated the salivary flow rate of NF1 individuals (n = 49) and compared to an age and sex-matched control group. We have also investigated the possible causes and consequences of hyposalivation in NF1 individuals through anamnesis, a specific questionnaire, physical examination, tongue coating evaluation and cytopathological exam to assess the prevalence of oral candidiasis. Hyposalivation at rest was present in 59% (29/49) of NF1 individuals in contrast to 22% (11/49) in the control group, being statistically significant (P <0.0001; Wilcoxon rank-sum test). The analysis of the adjusted residual showed that the prevalence of hyposalivation in NF1 individuals (46.9%) was 4-fold higher than in controls (10.2%). None of the possible causes of hyposalivation (medication...Continue Reading
