Objective: The present study aimed to develop and validate an animal model of chemotherapy-induced oral mucositis due to cisplatin administration.
Materials And Methods: Oral mucositis was induced in Wistar rats by cisplatin. Twenty healthy male Wistar rats were divided into four groups: a control group, and cisplatin 3 mg/kgBW (D1), cisplatin 5 mg/kgBW (D2), and cisplatin 6 mg/kgBW groups (D3). The D1, D2, and D3 groups received the cisplatin intraperitoneally on days 1, 3, and 5, whereas the control group did not receive anything. On day 7 and day 14 the entire experiment was terminated in all groups and the changes in body weight, oral mucositis grades, and histopathological scores were evaluated.
Results: Cisplatin administration created a strong oral mucositis effect on groups D2 and D3. All the cisplatin doses decreased the rats' body weight by day 14. The worst oral mucositis grades and histopathological scores resulted from the administration of cisplatin at a dose of 5 mg/kgBW.
Conclusions: In conclusion the cisplatin 5 mg/kgBW administered on days 1, 3, and 5 by intraperitoneal administration was the optimum dose to induce oral mucositis.

Over the past few decades, dental implants have been successfully utilized to replace teeth lost due to periodontal disease and other conditions. However, similar to natural teeth, dental implants are vulnerable to inflammatory peri-implant diseases, which can compromise their long-term viability. This review aims to summarize the current understanding of peri-implant diseases and discuss effective strategies for their diagnosis, treatment, and long-term management.

Background: Oncolytic viruses (OVs) are increasingly recognized as promising tools for cancer therapy, as they selectively infect and destroy tumor cells while leaving healthy cells unharmed. Despite considerable progress, the limited therapeutic efficacy of OV-based virotherapy continues to be a significant challenge in cancer treatment.
Methods: The SMAC/DIABLO gene was inserted into the genome of vesicular stomatitis virus (VSV) to generate VSV-S.

Statement Of Problem: Acrylic denture base resins are subject to colonization by oral and nonoral bacteria, contributing to the onset of denture stomatitis. However, how the addition of antimicrobial substances affects the mechanical and optical properties of additively manufactured denture base resin remains unclear.
Purpose: The purpose of this in vitro study was to investigate the surface roughness, color stainability, and flexural strength of antimicrobial-modified, additively manufactured polymethyl methacrylate (PMMA) denture base resin in tooth and gingiva colors.

Recurrent aphthous stomatitis (RAS) is a common condition that manifests as ulcerative lesions in the oral mucosa. In this study, bilayer, mucoadhesive nanofibers loaded with pomegranate flower extract (PFE) were prepared using thiolated gelatin (TGel) and thiolated chitosan (TCS) as the active layer and drug-free polycaprolactone (PCL) as the backing layer. Gelatin (Gel) and chitosan (CS) were successfully thiolated (proven by Ellman's assay, solubility, H NMR, FTIR, Raman spectroscopy, and XRD) and electrospun into active nanofibrous layers with a diameter of 356.

The Junín virus (JUNV) is one of the New World arenaviruses that cause severe hemorrhagic fever. Human transferrin receptor 1 (hTfR1) has been identified as the main receptor for JUNV for virus entry into host cells. To date, no treatment has been approved for JUNV.
