Nanostructured patches composed of bacterial nanocellulose (BNC), hyaluronic acid (HA) and diclofenac (DCF) were developed, envisioning the treatment of aphthous stomatitis. Freestanding patches were prepared via diffusion of aqueous solutions of HA and DCF, with different concentrations of DCF, into the wet BNC three-dimensional porous network. The resultant dual polysaccharides-based patches with a nanostructured morphology present thermal stability up to 200 °C, as well as good dynamic mechanical properties, with a storage modulus higher than 1.0 GPa. In addition, the patches are non-cytotoxic to human keratinocytes (HaCaT cells), with a cell viability of almost 100% after 24 h. The in vitro release profile of DCF from the patches was evaluated in simulated saliva, and the data refer to a diffusion- and swelling-controlled drug-release mechanism. The attained results hint at the possibility of using these dual polysaccharides-based oral mucosal patches to target aphthous stomatitis.

Previous studies have suggested potential associations between some dietary factors and oral mucosal lesions (OMLs), however, existing research could be biased due to limited sample size and unaccounted confounding factors. This study aimed to explore the causal relationships between 13 common dietary factors and 3 OMLs using 2-sample Mendelian randomization (MR) analysis. Data for the MR analysis were extracted from publicly available genome-wide association study statistics.

Unlabelled: : Introduction: To assess the frequency and clinical-immunologic characteristics of immune-related comorbidities in children with genetically confirmed Familial Mediterranean Fever.
Methods: This cohort study included 132 pediatric patients with followed at a tertiary care center. Patients were stratified into two groups based on the presence or absence of immune-related comorbidities.

Background: Social media is increasingly utilised as a means of disseminating oral health information. Recurrent aphthous stomatitis (RAS) is the most common ulcerating condition of the oral mucosa.
Aim: The aim of this study was to evaluate the quality of TikTok videos concerning RAS.

Recurrent aphthous stomatitis (RAS) is a very frequent condition in developed countries whose basic symptom is a lesion referred to as an aphthous ulcer. High levels of interleukin (IL)-1 and IL-6 and low salivary levels of IL-10 are the basis of RAS pathogenesis. Sublingual supplements based on IL-10 can be very useful in reducing the phenomenon of aphthous recurrence in patients with RAS.

Recurrent aphthous stomatitis (RAS) is the most common ulcerative disorder of the oral cavity, although its etiology is still unknown. The present study aimed to identify the proteomic profile associated with the RAS inflammatory process, thereby enhancing our understanding of its etiopathogenesis. We compared salivary protein profiles of RAS patients during an active episode of oral ulceration (30 patients, mean age 36.
