In this work, we established an in vivo murine model of herpes simplex virus type 1 (HSV-1) infection involving inoculation by scarification of the oral mucosain order to study its dissemination towards the trigeminal ganglion (TG). Both viral DNA and infectious virions were detected on the third day postinfection (p.i.). Viral proteins revealed by immunohistochemistry were mainly found at seven days p.i., when the latency-associated transcript (LAT) was also detected. This model simulated the dissemination process of HSV-1, which could be used to study herpes pathogenesis starting in the oral mucosa.

As the supply source for gingival grafts, the palatal tissue possesses marked regenerative ability after repeated wounding over the buccal attached gingiva and skin. However, the intrinsic mechanisms are poorly understood. Schwann cells reportedly participate in wound repair of many tissues.

Oral lichen planus (OLP) is a chronic T cell-mediated inflammatory mucosal disease of unknown etiology. The lack of suitable animal models has hampered understanding of its etiopathogenesis. This study aimed to clarify the contribution of bacterial infection and zinc deficiency (ZD) in OLP pathogenesis by developing a murine model.

Background: Chronic tobacco use, in any form, induces significant cellular alterations in the oral mucosa. This study investigates four distinct cytomorphological changes in oral mucosal cells among smokeless tobacco users, examining their association across different genders and age groups.
Materials And Methods: This cross-sectional study involved collecting mucosal samples from smokeless tobacco (naswar/snuff) users through consecutive sampling.

This study aimed to apply finite element analysis (FEA) to simulate the oral environment of a patient with an implant-supported overdenture prosthesis. A 3D mandibular model was created for a 45-year-old female patient from CT images, with mucosal thickness measured at 3 mm on average using ultrasonography. The overdenture prosthesis was scanned with an intraoral scanner and placed onto the 3D mandibular model.

The pathogenesis of necrotic enteritis (NE) involves complex gene regulation at both the bacterial cell and host tissue levels, yet many aspects remain incompletely understood. This study aims to compare the differential transcriptome of the netB-positive Clostridium perfringens strain, CP54, before and after infection. Differentially expressed genes and pathways were also examined in jejunal tissues from CP54-induced and CP54-Eimeria coinfected NE models to identify potential targets for mitigating NE.
