While skin wounds heal by scarring, wounds of oral mucosa show privileged healing with minimal scar formation. Our hypothesis was that phenotypic differences between oral and skin fibroblasts underlie these differences in healing. The aims of this study were to compare MMP-3 expression by oral and skin fibroblasts and investigate a role for MMP-3 in mediating collagen gel contraction. Oral fibr...
Mouth-exhaled hydrogen cyanide (HCN) concentrations have previously been reported to originate from the oral cavity. However, a direct correlation between the HCN concentration in oral fluid and in mouth-exhaled breath has not been explicitly shown. In this study, we set up a new methodology to simultaneously measure HCN in the headspace of oral fluid and in mouth-exhaled breath. Our results sh...
Background: Different treatment and protective approaches for radiation-induced oral mucositis have been practiced and have varieties of success. Of which, radioprotective agents, synthetic or natural, have been of great interest for researchers. This study aims to evaluate the effect of curcuma longa topical gel as a herbal production on mucositis induced by radiation therapy of head and neck ...

lichen planus (lp) is a chronic inflammatory disease of probable immune-based etiology. the pathogenesis of lp is unclear, but apoptotic changes in epidermal (epithelial) cells have been reported. destruction of the basal cell layer is observed and many changes in cell proliferation, cell repair and cell death occur in the injured mucosal epithelium. the aim of this study was to evaluate and co...
Drooling beyond the age of 4 years is neurodevelopmentally abnormal. Chronic "sialorrhoea" is seen in children with abnormal oral sensation and/or motor control and more infrequently when there is excessive production of saliva. Salivary production from the paired glands is under autonomic parasympathetic control. Management of the problem relies on multidisciplinary teams with a focus on asses...
Two patients with dihydropteridine reductase (DHPR) deficiency, in one case due to the absence of any enzyme protein (DHPR- cross reactive material (CRM)-) and in the other case due to the production of a mutant type devoid of catalytic activity (DHPR- CRM+) were examined. This latter form of malignant phenylketonuria, whose relative frequency seems to be higher in the Italian population, possi...
BACKGROUND A small population of patients with severe asthma does not respond to glucocorticoids (steroid resistant [SR]). They have high morbidity, highlighting an urgent need for strategies to enhance glucocorticoid responsiveness. OBJECTIVE We investigated the immunologic differences between steroid-sensitive (SS) and SR asthmatic patients and the effect on immunophenotype of oral calcitri...
Saliva is a key element in oral homeostasis, oral function and maintenance of oral health. Dry mouth has multiple oral health consequences and affects quality of life. The incidence of dry mouth and its public health impact are increasing due to the aging population, the effects of some systemic diseases, and medical management and commonly prescribed medications that reduce saliva production. ...
IL-10 is an immunoregulatory cytokine that can modulate immune processes, inhibiting the expression of inflammatory T(h)1 type responses as well as affecting antigen-presenting cell function. In addition, IL-10 has been shown to be active at mucosal surfaces. In the present study, we examined the role of IL-10 on orally and nasally induced tolerance. Treatment of (PL/J x SJL)F(1) mice with low-...
