Article Abstract

This study aimed to develop nanoaggregates of berberine-phospholipid complex incorporated into thiolated chitosan (TCS) hydrogel for the treatment of aphthous stomatitis. The berberine-phospholipid complex was formulated through the solvent evaporation technique and assembled into nanoaggregates. TCS was synthesized through the attachment of thioglycolic acid to chitosan (CS). Nanoaggregates-TCS was prepared by the incorporation of nanoaggregates into TCS and underwent and tests. Nanoaggregates-TCS exhibited prolonged release of berberine. The mucoadhesive strength of nanoaggregates-TCS increased 1.75-fold compared with CS hydrogel. studies revealed the superior therapeutic efficacy of nanoaggregates-TCS compared with that of other groups. Due to prolonged drug release, appropriate residence time and anti-inflammatory effects, nanoaggregates-TCS is an effective system for the treatment of aphthous stomatitis.

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.

Objective: Recurrent aphthous stomatitis (RAS) is a common inflammatory condition of the oral mucosa with a multifactorial etiology, in which cytokine dysregulation is believed to play a central role. However, studies evaluating interleukin (IL)-1β, IL-6, and IL-10 levels and their genetic variants in RAS have yielded inconsistent results, likely due to population heterogeneity and methodological differences.

Materials And Methods: This systematic review synthesizes current evidence on the association between single nucleotide polymorphisms (SNPs) of IL1β, IL6, and IL10 and susceptibility to RAS.
