Review
The fluorescence method is an innovative technique used by pathologists for examining body mucosa, and for the abnormalities tissue screening, potentially leading to the earlier discovery of pre-cancer, cancer or other disease processes. The early detection is one of the best mechanisms for enabling treatment success, increasing survival rates and maintaining a high quality of life. The purpose of this review is to evaluate the clinical efficiency of this diagnostic tool applied to the oral cavity (VELscope). A literature systematic review has been performed. The initial research provided 53 results after applying the inclusion and exclusion criteria, and after a manual screening of the abstracts by the authors, only 25 results were eligible for review. The results and data contained in all the researches, no older than 10 years, were manually evaluated, and provided useful information on this diagnostic method. The VELscope mean value about sensitivity and specificity resulted of 70.19% and 65.95%, respectively, by results analysis, but despite this some studies disagree about its clinical effectiveness, and this diagnostic method is still much debated in scientific and clinical medical literature. Surely being able to have efficient and effective tools from this point of view could help the clinician in the diagnosis, and also make timelier the pharmacological or surgical therapy, improving the quality of life of the patient, and in some cases guaranteeing a longer survival term.

Review
AIM
The aim of the present systematic review was to investigate the risk of malignant transformation of proliferative verrucous leukoplakia (PVL).
MATERIALS AND METHODS
the search was carried out using a combination of terms (leukoplakia OR leucoplakia) AND (multifocal OR proliferative) on the following databases: PubMed, Scopus, Web of Science (WOS Core Collection), Cochrane Library, selecting only articles published since 1985 and in the English language. Demographic, disease-related, and follow-up data extracted from the studies included in the qualitative synthesis were combined. Weighted means ± standard deviations were calculated for continuous variables, while categorical variables were reported as frequencies and percentages. Dichotomous outcomes were expressed as odd ratios (ORs) with 95% confidence intervals (CIs). Odd ratios for individual studies were combined using a random-effects meta-analysis, conducted using Review Manager 5.4 Software (Cochrane Community, Oxford, England).
RESULTS
twenty-two articles were included, with a total of 699 PVL patients, undergoing a mean follow-up of 7.2 years. Sixty-six percent of patients were females, with a mean age of 70.2 years, and 33.3% were males, with a mean age of 59.6 years. Most patients were non-smokers and non-alcohol users, and the gingiva/alveolar ridge mucosa was the most involved anatomical site by both PVL appearance and malignant transformation. A total of 320 PVL patients developed oral verrucous carcinoma (OVC) or conventional oral squamous cell carcinoma (OSCC) because of malignant transformation of PVL lesions (45.8%). A statistically significant 3.8-fold higher risk of progression to conventional OSCC was found compared to OVC in PVL patients, with women being 1.7 times more likely to develop oral cancer than men, as a consequence of PVL progression. Moreover, a statistically significant higher likelihood of developing conventional OSCC in female PVL patients than in males was found. In 46.5% of patients with PVL malignant transformation, multiple carcinomas, in different oral sites, occurred during follow-up.
CONCLUSIONS
PVL is an aggressive lesion, which, in a high percentage of cases (almost 50%), undergoes malignant transformation, mainly toward OSCC. The female gender is most affected, especially in the elderly, with a negative history for alcohol and tobacco consumption.

Review
BACKGROUNDS
Oral submucous fibrosis (OSMF) is a chronic, insidious disease and is said to have a multifactorial origin with varied clinical manifestation of repeated oral ulcers, intolerance to spicy food, mucosal blanching resulting in stiffness of the oral mucosa and formation of taut bands leading to reduced mouth opening. We designed this study to systematically review the literature on QOL in OSMF and hope to make recommendations for future course of QOL assessment in OSMF.
METHODS
An electronic bibliographic search of studies was done from year 1900-2019 using specified keywords. The following databases were searched: PubMed, Ovid, Google Scholar and manual search were done from references of relevant articles. Of the screened 156 articles, finally 10 studies were included after screening for inclusion/exclusion criteria. Quality assessment of studies was completed using the Effective Public Health Practice Project (EPHPP) criteria for quantitative studies.
RESULTS
Most instruments used in the studies were not disease specific for OSMF except one study. Six types of questionnaires were used. The heterogeneity in study population, study designs, QOL instruments and outcome measures made it difficult for a comparison. Therefore, a quantification analysis was not possible. Also pure OSMF data without the involvement of other lesions were less in number.
CONCLUSIONS
OSMF not only physically debilitates a patient, it has its repercussions on the social, physical, psychological domains as well. Another aspect is that apart from trismus, which is the most common and evident symptom associated with OSMF, a substantial part of the suffering that ensues is also because of the ulcerations, burning sensation and worsening of dental health. Another focus was the association of worse QOL with a higher grade of disease, longer and higher tobacco abuse contact duration. This review is unable to give a confident answer to the evidence on QOL in OSMF but definitely showers light on the evident lack of robust data on the same. Robust methodological and adequately powered studies on assessing QOL in OSMF using only a reliable disease specific questionnaire is the need of the hour.

Meta-Analysis
The objective of the present article was to qualitatively and quantitatively review the association between chronic mechanical irritation and oral squamous cell carcinoma (OSCC). PubMed, SCOPUS, and Web of Science databases were searched using the keyword combinations "chronic trauma and oral squamous cell carcinoma; chronic irritation and oral squamous cell carcinoma; chronic irritation and oral cancer; and chronic trauma and oral cancer." Duplicates and irrelevant articles were excluded after the title and abstract screening. The full texts of the remaining articles were assessed using selection criteria. A total of 375 (PubMed-126; SCOPUS-152; WOS-97) articles were screened, and 343 duplicates and irrelevant articles were excluded from the study. Only 9 of the remaining 32 articles met the selection criteria and were included in the qualitative analysis. Buccal mucosa and tongue, being highly prone to chronic irritation through the dental prosthesis, were the common sites for OSCC. Edentulous subjects with ill-fitting dentures were at a high risk of developing chronic irritation associated-OSCC. According to the Joanna Briggs Institute of risk assessment, eight of the nine included studies had a low risk of bias. The quantitative analysis showed a significant association (p < 0.00001) between the chronic oral mucosal irritation and OSCC with an overall risk ratio of 2.56 at a confidence interval of 1.96-3.35. Chronic oral mucosa irritation has a significant association with OSCC, and the nature of association could be that of a potential co-factor (dependent risk factor) rather than an independent risk factor.

Review
BACKGROUND
Lung cancer metastasis to oral region is very rare. Studies have been published analysing the cases of metastatic tumours to the oral cavity by many researchers. But very few research work has been conducted till date to analyse only the oral soft tissue metastasis from Lung cancer as the primary source. The goal of this study was to examine published cases of oral soft tissue metastasis from lung cancer as the only primary source from 1st August 1977 to 31st December 2021.
MATERIAL AND METHODS
An electronic search of the published English literature was performed in PubMed/ Medline, Scopus, Google Scholar, and Research gate databases, using keywords like 'Lung cancer', OR/ AND 'Lung carcinoma' OR/ AND 'Oral cavity', OR/AND 'Metastasis', OR/AND 'Primary', OR/AND 'Source', OR/AND 'Initial', OR/AND 'Tongue', OR/AND 'Palate', OR/ AND 'Tonsil', OR/AND 'Lip', OR/AND 'Buccal mucosa', OR/AND 'Floor of mouth', OR/AND 'Salivary glands', OR/ AND 'Parotid', OR/ AND 'Submandibular', OR/ AND 'Sublingual' OR/ AND 'Mandible', OR/AND 'Maxilla. We also searched all related journals manually. Reference list of all articles was also checked.
RESULTS
Our research revealed total 122 patients. The most prevalent diagnosed metastatic lung cancer was adenocarcinoma. Gingiva, tongue and tonsils were the most common site of metastasis. 54% patients died of metastasis with a survival time of 1 week to 2.5 years.
CONCLUSIONS
Oral soft tissue metastasis from lung cancer has a bad prognosis. More cases need to be published in order to raise awareness of these lesions and gain a better understanding of their characteristics. Lung cancer, metastasis, oral, primary, soft tissues.

Review
(1) Purpose: In this article, the authors decided to systematically review the available literature to identify potential correlations regarding secondary oral carcinoma occurring after hematological systemic treatment and oral chronic graft-versus-host disease. (2) Methods: Medline (PubMed) and Scopus (Elsevier) databases were searched, including articles from the years 2002-2022. The 33 unique results were assessed by a PRISMA flowchart, and we rejected 24 papers and included 9 articles in the review. (3) Results: The majority of patients suffered from the oral form of chronic graft-versus-host disease before the diagnosis of oral malignancy. Two common cancer sites were the tongue and buccal mucosa. The exact percentage of secondary oral carcinoma after hematopoietic stem cell transplantation could not be estimated due to a lack of data. (4) Conclusions: Every physician taking part in the follow-up of patients after hematological treatment should be aware of the possibility of secondary neoplastic disease in the oral cavity, especially in patients with oral graft-versus-host disease. Proper follow-up protocols and monitoring are needed in this patient group as the cause of these cancers appears to be multifactorial.

Review
Chronic kidney disease is classified as a civilization disease and is being diagnosed in an increasing number of patients. Hypertension and diabetes mellitus often coexist in hemodialyzed patients. The aim of the present study was to identify publications on the oral cavity status of multimorbid hemodialyzed adult patients additionally diagnosed with hypertension and/or diabetes mellitus, published between 2012 and 2022 to establish evidence of the impact of hypertension and diabetes mellitus on the oral status of hemodialyzed patients. Scopus and Web of Science databases were searched. Eight articles were included in the review. In total, 3 articles discussed oral hygiene in hemodialyzed patients, 4 discussed periodontal status, 3 discussed mucosa condition and saliva parameters, and 3 discussed the problem of Candidiasis infections. The conclusions were as follows: there is still a limited number of publications discussing the oral status of hemodialyzed patients diagnosed with hypertension; involved articles have proven that coexisting diseases can influence the oral cavity status of hemodialyzed patients and cause periodontal disorders, lower hygiene status, saliva parameters and make the risk of Candida infections higher.

INTRODUCTION
Human papillomavirus (HPV) infection is mainly a problem of the female reproductive tract. It can occur in the oral cavity as well. Commonly HPV infections are subclinical, without any visible symptoms, and last no longer than 2 years. Usually the clinical manifestation of HPV infection is benign, but in some cases it can also promote malignant transformation. In the paper we have tried to estimate the prevalence of HPV detected in samples of oral leukoplakia (OLK), the most common premalignant lesions of the oral mucosa.
AIM
To review the current literature to estimate the prevalence of HPV (HPV DNA) detected in samples of oral leukoplakia.
MATERIAL AND METHODS
We searched PubMed/Medline, Scopus, and Cochrane Library databases for studies that examined the prevalence of HPV in leukoplakia with HPV DNA detection by polymerase chain reaction.
RESULTS
HPV positive cases in OLK ranged from 0% to 100% in studies. The overall HPV prevalence in leukoplakia was 6.66%. The prevalence of HPV 16 positive cases was 2.95%. The high-risk HPV prevalence was 5.16%, when the low-risk HPV prevalence was 3.32%. When dysplasia is mentioned, HPV was detected in 19.56% of lesions with dysplasia, compared to 38.16% among non-dysplastic lesions.
CONCLUSIONS
Further studies should be extended also to include low-risk HPV and compare its prevalence with presence of dysplasia in leukoplakia. Besides, leukoplakia and other premalignant lesions can no longer be treated as one lesion.

Meta-Analysis Review
OBJECTIVE
The purpose was to describe whether there are field cancerization (FC) indicators in clinically normal mucosa opposite to primary oral squamous cell carcinoma (OSCC).
METHODS
A search of the Cochrane Library, PubMed, Embase, Web of Science, Scopus, and Livivo databases was performed on June 12, 2022, which retrieved 152 records without duplicates. Studies that analyzed FC in biopsies in clinically normal tissue opposite to primary OSCC were included. The search was conducted under the PRISMA guideline and the protocol was registered in PROSPERO (CRD42017077125).
RESULTS
Eight articles with 302 patients were included, 192 men and 110 women, mean age 57.1 years. Most patients had deleterious habits. All studies performed histopathological confirmation of OSCC and biopsies were obtained the clinically normal mirror mucosa. The meta-analysis carried out with eight studies. The studies showed 57.3 % of cases with histopathological changes of clinically normal mucosa opposite to primary OSCC (Confidence interval 95 %, 0.443-0.703; heterogeneity: Q value 18.715; I 73.284 %; n = 205). p53 and Ki-67 immunohistochemical analysis may be predictive for detecting changes. There was p53 immunoexpression in 41.3 % of cases (p = 0.872) (n = 55), ki-67 immunoexpression (< 20 %) in 68 % (p = 0.001) (n = 97) and ki-67 immunoexpression (> 20 %) in 28.4 % of cases (p = 0.000) (n = 110).
CONCLUSIONS
The findings suggest that FC can occur, and there are histopathological changes in clinically normal tissue opposite to primary OSCC. Nevertheless, the review showed that more longitudinal studies on FC are needed to draw a conclusive indication of the occurrence of FC in oral tissues opposite to OSCC.

Review
Oral candidiasis is the most common opportunistic fungal infection caused by commensal species. Since there are various local and systemic predisposing factors for the disease, the treatment also varies from topical to systemic antifungal agents. Nystatin is a common antifungal agent used topically. The aim of this systematic review was to evaluate and compare the efficacy of different antifungal agents and the safety of nystatin in the treatment of oral candidiasis. Three electronic databases were searched for randomized controlled trials comparing nystatin with other anti-fungal therapies or placebo. Clinical and/or mycological cure was the outcome evaluation. A meta-analysis and descriptive study on the efficacy, treatment protocols, and safety of nystatin was also conducted. The meta-analysis included five studies, which compared the efficacy of nystatin suspensions with photodynamic therapy. A significant difference in the colony-forming units per milliliters (CFU/mL) of species was observed at 60 days intervals for both palatal mucosa and denture surfaces, with both groups favoring nystatin with low heterogeneity at a 95% confidence interval. Nystatin and photodynamic therapy were found to be equally effective for the clinical remission of denture stomatitis as well as a significant reduction of CFU/mL of species from dentures and palatal surfaces of the patients.
