Abstract
Morsicatio linguarum is an uncommon disorder caused by continuous biting of the tongue, generally the borders. It is usually found among people who are stressed or psycholo-gically impaired. Clinically, morsicatio linguarum presents as a macerated grey-white patch or plaque of the lingual mucosa. It is frequently misdiagnosed as it is confused with other clinically identical lesions involving the lingual mucosa. In this report, a case of bil-ateral morsicatio linguarum in a 44-year-old male patient with a history of tongue biting is presented.

Abstract
The oral cavity as the second most various microbial community in the body contains a broad spectrum of microorganisms which are known as the oral microbiome. The oral microbiome includes different types of microbes such as bacteria, fungi, viruses, and protozoa. Numerous factors can affect the equilibrium of the oral microbiome community which can eventually lead to orodental infectious diseases. Periodontitis, dental caries, oral leukoplakia, oral squamous cell carcinoma are some multifactorial infectious diseases in the oral cavity. In defending against infection, the immune system has an essential role. Depending on the speed and specificity of the reaction, immunity is divided into two different types which are named the innate and the adaptive responses but also there is much interaction between them. In these responses, different types of immune cells are present and recent evidence demonstrates that these cell types both within the innate and adaptive immune systems are capable of secreting some extracellular vesicles named exosomes which are involved in the response to infection. Exosomes are 30-150 nm lipid bilayer vesicles that consist of variant molecules, including proteins, lipids, and genetic materials and they have been associated with cell-to-cell communications. However, some kinds of exosomes can be effective on the pathogenicity of various microorganisms and promoting infections, and some other ones have antimicrobial and anti-infective functions in microbial diseases. These discrepancies in performance are due to the origin of the exosome. Exosomes can modulate the innate and specific immune responses of host cells by participating in antigen presentation for activation of immune cells and stimulating the release of inflammatory factors and the expression of immune molecules. Also, mesenchymal stromal/stem cells (MSCs)-derived exosomes participate in immunomodulation by different mechanisms. Ease of expansion and immunotherapeutic capabilities of MSCs, develop their applications in hundreds of clinical trials. Recently, it has been shown that cell-free therapies, like exosome therapies, by having more advantages than previous treatment methods are emerging as a promising strategy for the treatment of several diseases, in particular inflammatory conditions. In orodental infectious disease, exosomes can also play an important role by modulating immunoinflammatory responses. Therefore, MSCs-derived exosomes may have potential therapeutic effects to be a choice for controlling and treatment of orodental infectious diseases.

Abstract
Notch signaling involves cell to cell contact. It is an ancient signaling mechanism that is conserved throughout the animal kingdom. The basic function of Notch signaling is to decide cell fate and execute asymmetrical division. Notch signaling is indispensable for embryo growth. Aberrant Notch signaling involves in cancer progression by altering cell proliferation rate, tumor micro-environment, stem cell activities. The role of Notch signaling in cancer progression is context-dependent. In breast cancer and T cell lymphoma Notch signaling is highly active, whereas in squamous cell carcinoma (SCC) as oral and skin cancer, the signaling is suppressed. It is believed that in SCC, Notch-mediated tumor growth is due to the cell non-autonomous function. Oral cancer is the 6th most risky cancer worldwide. In many patients, oral cancer is preceded by pre-cancer conditions. In this review, we have summarized the research knowledge related to the role of Notch signaling in oral cancer and pre-cancer conditions and the therapeutic options available targeting different components of Notch pathways.

[PMID: 35153425 PMCID: PMC8820305 DOI: 10.4103/njms.njms_324_21] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/19/2021] [Revised: 03/29/2021] [Accepted: 04/26/2021] [Indexed: 11/26/2022] Open
Abstract
The purpose of the current article was to evaluate the recently published researches on the use of lycopene and curcumin in oral leukoplakia (OL) and oral submucous fibrosis (OSF). A comprehensive review of the current researches enveloping PubMed, Ovid, and Cochrane was made using the keywords [(Lycopene) OR (Curcumin) AND (Leukoplakia OR OL OR OSF OR OSMF OR OSF OR Submucous Fibrosis)]. We included only randomized control trials and in the English language. The search covers the data from 1994 to August 2020. Six studies (2 of OL and 4 of OSF) finally qualified are included in the study for the qualitative analysis of the result. Out of these six studies, four were found having high risk, one with unclear risk and one with low risk. Only one study came out as finally suitable for the quantitative analysis of the result. A total of 90 participants were included in this review, with a mean age of 32 with a range of 17–60 years. Out of 90 participants, 70 were male and 20 were female. It is evident from the result of this study that the use of oral curcumin and lycopene has significant improvement in the mouth opening, burning sensation, and cheek flexibility in comparison to the placebo. The use of oral curcumin and lycopene appears to be effective and safe in the treatment of OL and OSF but to read the result of use of oral curcumin and lycopene in OL caution should be taken because of bias.

Abstract
The diagnosis of oral white lesions might be quite challenging. White lesions are only 5% of all oral pathologies. Smokeless tobacco (ST), also known as tobacco chewing, spit tobacco, dip, plug, or chew, is one of the well-documented agents that causes white lesions. The use of ST is associated with a variety of oral cavity lesions, including tooth decay, periodontal disease, tooth loss, leukoplakia, keratosis, oral cancers such as carcinoma-in situ, verrucous carcinoma, and invasive squamous cell carcinoma. The prevalence and severity of lesions are dose related. Therefore, it can be best predicted by the amount, frequency, and duration of ST used. This case report highlights an unusual presentation of an adolescent child presenting in the orthodontic retention phase that was originally misdiagnosed as gingival recession due to treatment. A clinical examination of the oral cavity and careful history taken should be routinely performed in every patient presenting at a dental office.

Abstract
Examination of the oral cavity can provide significant diagnostic information regarding the general health of the patient. The oral cavity is affected by a multitude of pathologic conditions of variable cause and significance; however, there are numerous normal variations of oral soft tissue structures that may resemble a pathologic state. Understanding these variations assists practitioners to discriminate between normal versus abnormal findings and determine the appropriate course of management, if necessary.

Abstract
Leukoplakia has evolved as a clinico-pathologic concept over many years, with the current clinical designation being accepted worldwide. Reflective of the biology of leukoplakia is the concept of cellular atypia and epithelial dysplasia. Adding to a better understanding of leukoplakia in general has been the definition of relevant clinical subsets which, in some cases, includes etiology (snuff), while in other cases a verrucous clinical appearance will suggest a more aggressive anticipated behavior pattern. Tobacco usage, in many of its forms, remains the prime etiologic factor; however, other considerations also apply. More recently, the potential etiologic role of Candida albicans has been stressed, as well as its possible role in carcinogenesis. So-called oral hairy leukoplakia has been defined in relation to a possible Epstein-Barr viral infection, usually in the immunosuppressed patient. Other viruses, human papilloma virus in particular, have been implicated in leukoplakia, while genetic alterations involving tumor suppressor elements (p53) have also been investigated. Finally, the management of this common condition remains a variable and includes local, topical, and systemic therapies such as anti-oxidants, carotenoids, and retinoids.
