Oral lichen planus (OLP) is a premalignant disease with unknown etiology. It has been demonstrated that inflammation and immune activation play a central role in the pathogenesis of OLP. Various cellular and molecular mechanisms are involved in the pathogenesis of OLP. Studies have shown that 2-7% of OLP patients develop oral squamous cell carcinoma (OSCC). As a result, determining the prognosis of the disease will be promising in preventing oral carcinoma. MicroRNAs are involved in the regulation of cytokine expression and cytokines have a central role in the pathogenesis of OLP. As a result, their evaluation in body fluids may be helpful in assessing the disease's status and progression, and facilitating the treatment process. In this regard, much attention has been paid to the saliva of OLP patients as the sampling is cost-effective and non-invasive. Here, we discuss the potential of miRNAs in predicting the disease severity and progression.

Mucosal-associated invariant T (MAIT) cells, a type of T lymphocytes with innate-like characteristics, are crucial in bridging innate and adaptive immunity. When activated, MAIT cells release various inflammatory molecules and swiftly respond to antigens. Notably, numerous studies highlight the significant impact of MAIT cells on tumors and various immune disorders by influencing the immune microenvironment.

Introduction: Oral lichen planus (OLP) is a chronic disorder affecting the oral mucosa, potentially associated with xerostomia, either independently or concurrently. Research suggests that approximately 45% of patients with erythematous and ulcerative OLP may experience dry mouth sensations. The aim of this systematic review is to assess the current literature regarding the potential relationship or co-occurrence of xerostomia with OLP.

Article Synopsis
- The study aimed to explore the relationship between Epstein-Barr virus (EBV) and two conditions: Oral Lichen Planus (OLP), an immune system disease, and Oral Lichenoid Contact Lesions (OLCL), an allergic reaction to dental materials.
- A total of 60 participants, including 20 with OLCL, 23 with OLP, and 20 healthy controls, underwent biopsies, saliva, and blood tests to detect the presence of EBV DNA using Real-time PCR.
- Results revealed that EBV DNA was somewhat present in both OLP and OLCL patients, with no significant difference noted compared to the control group, suggesting more research is needed to clarify EBV's role in these conditions
