Review
BACKGROUND AND OBJECTIVES
In order to detect genetic damage, different methods have been developed, such as micronuclei and comet assay. The comet assay presents some advantages when compared to the other aforementioned methods, including wide versatility, as any eukaryotic cell can be evaluated at an individual cellular level. In this context, the aim of this systematic review was designed to help further elucidate the following question: is the comet assay a suitable biomarker of oral carcinogenesis?
MATERIAL AND METHODS
The present systematic review was performed in accordance with the Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) guidelines. Full manuscripts from 18 studies were carefully selected in this setting.
RESULTS
A total of 15 studies demonstrated positive findings for genotoxicity in peripheral blood or oral cells in patients with pre-malignant lesions or oral cancer. In the quality assessment of studies, 1 was classified as Strong, 5 were considered as Moderate, and 12 were classified as Weak.
CONCLUSION
In summary, the comet assay can be a useful biomarker for oral carcinogenesis. However, further studies with more strict parameters are suggested (with less uncontrolled confounders) in order to increase findings reliability for diagnosis of oral potentially malignant lesions.

Meta-Analysis Review
OBJECTIVE
The objective of this study was to assess the risk and prevalence of oral cancer in patients with systemic lupus erythematosus (SLE) or discoid lupus erythematosus (DLE).
STUDY DESIGN
The review included observational cohort and cross-sectional studies that investigated the incidence or prevalence of oral cancer in adults with confirmed diagnoses of SLE or DLE. Studies were selected based on predefined eligibility criteria, including the use of specific diagnostic criteria for SLE and DLE. After searches in PubMed/MEDLINE, EMBASE, Scopus, Web of Science, LILACS, and LIVIVO databases and gray literature for relevant studies, the selection process was conducted by independent reviewers.
RESULTS
A total of 5,545 articles were identified. After screening, 8 studies met the inclusion criteria. The pooled risk estimate indicated a significantly increased risk of oral cancer in patients with SLE (risk ratio = 2.69; 95% confidence interval, 1.75 to 4.16; I = 0%; P = .78) compared with the general population. The pooled prevalence of oral cancer in patients with DLE was 10% (95% ci, 0.03 to 0.13; I = 59%; P = .12).
CONCLUSIONS
This review provides evidence supporting an elevated risk for individuals with SLE or DLE developing oral cancer. The findings highlight the importance of monitoring oral mucosa in patients with these conditions.

Meta-Analysis Review
Oral mucositis is a common and debilitating side effect induced by stem cell transplantation that is experienced by cancer patients undergoing chemotherapy or radiation therapy. This condition involves inflammation and ulceration of the oral mucosa, leading to pain, difficulty with eating and speaking, and an increased risk of infections. Mucositis not only compromises the quality of life for cancer patients, but also affects treatment outcomes and may necessitate dose reductions or treatment delays. This scientific article provides a comprehensive overview of mucositis. The purpose of this literature review with a meta-analysis is to evaluate the efficacy of laser therapy in treating post-transplant mucositis. : A search of the literature from 3 May 2023 was carried out on three online databases, PubMed, Scopus, and Web of Science. Only studies that treated patients with laser therapy were considered; only studies with the placebo-treated control group were considered. Review Manager version 5.2.8 (Cochrane Collaboration) was used for the pooled analysis. We measured the std. mean difference between the two groups (laser and placebo). : There were 230 papers included in this review. Two hundred twenty-seven were excluded. Furthermore, a manual search was performed. After the search phase, three articles were considered in the study. The overall effect showed differences in the degree of mucositis in the laser-treated patients compared with the placebo group. The meta-analysis shows a reduction in the degree of mucositis in the patients treated with laser therapy (std. mean difference -1.34 [-1.98; -0.98]; C.I. 95%). : The application of laser therapy results in decreased severity of oral mucositis from radiation and chemotherapy. Our study shows that the application of low-level laser therapy in the treatment of transplant mucositis has excellent efficacy in relieving the symptoms and severity of mucositis.

Review
BACKGROUND
Recurrent aphthous stomatitis (RAS) is the most common ulcerative disease that affects oral mucosa. The coating agents, topical analgesics, and topical steroids are usually used as treatment methods. has been used for RAS treatment based on its anti-inflammatory, antioxidant, and immunomodulatory properties. In this study, a systemic review on the therapeutic effect of topical licorice on RAS management was performed.
METHODS
Science Direct, Scopus, Cochrane databases, PubMed Google Scholar, and ResearchGate were searched up to September 2021 to find all English randomized clinical trials studying the effect of , or its compositions on RAS. Meta-analysis was not conducted because of data heterogeneity. Articles were reviewed qualitatively, and only those with a Jadad score ≥3 were included. Animal studies, , review papers, non-English papers, and case reports were excluded.
RESULTS
Six studies with 314 subjects were included after screening. The result showed licorice has significant effects on RAS pain reduction, ulcer size, and healing time. Its effectiveness is related to its dose-dependent anti-inflammatory and antioxidant effects through several mechanisms. It also has antibacterial effects against and as another mechanism of action in RAS treatment. In addition, licorice can elevate the epidermal growth factor (EGF) level compared to the control group, which has an essential role in oral mucosal tissue integrity.
CONCLUSION
Licorice extract has been used in different dosage forms, including paste, patch, and mouthwash with concentrations of 1% or 5%. The healing time after licorice therapy is expected to be within 4-8 days. Licorice did not show any adverse effect in the intervention groups, indicating its effectiveness and safety in RAS treatment.

Review
OBJECTIVE
To determine the prevalence of human papillomavirus (HPV) in oral squamous cell carcinoma (OSCC) across Asian countries, focusing on South and Southeast Asia.
METHODS
A systematic search of four databases-MEDLINE/PubMed, EMBASE, Scopus, and ProQuest-was conducted to identify observational studies published between January 2013 and December 2023. The pooled prevalence of HPV was estimated using random-effects models, and subgroup analysis was performed to investigate the source of heterogeneity.
RESULTS
A total of 77 studies were included, comprising 7289 OSCC cases from 11 countries. The pooled HPV prevalence in OSCC was 23.1% (95% CI 17.9-28.7, I = 96.7%). South Asia had the highest prevalence (27.1%), followed by East Asia (19.4%), and Southeast Asia (16.7%). Two subtypes were commonly reported: HPV-16 (9.1%) and HPV-18 (5.1%). Anatomical subsites, buccal mucosa (34.0%), and floor of the mouth (33.2%) had similar ranges of HPV prevalence. All studies exhibited a high degree of heterogeneity, with the OSCC location and risk of bias identified as potential sources of heterogeneity.
CONCLUSIONS
Due to the high HPV prevalence in OSCC in Asia, HPV detection in routine pathology practice is recommended. Future studies should be conducted in multicentre settings using similar HPV detection methods and reporting detailed demographic and clinical information on oral sub-sites.

BACKGROUND
Oral Lichen Planus is a common chronic inflammatory disease of the oral mucosa. The prevalence in adults ranges between 0.5% and 2%, while in children is reported to be about 0,03%. Clinical features of Oral Lichen Planus could be variable in both adults and children, ranging from painless white hyperkeratotic lesions to painful erythematous atrophic ones. Actually, there are no systematic reviews in the literature on OLP in children, whereby this paper aims to summarize all the pathophysiological aspects and identify all cases described in the literature of Oral Lichen Planus in children, reporting their clinical characteristics.
MATERIAL AND METHODS
A systematic review of the literature was performed in online databases including PubMed, Scopus, Web of Science, Science Direct, EMBASE. In addition, in order to identify reports not otherwise identifiable, an analysis of the gray literature was performed on google scholar and in Open Gray.
RESULTS
By literature analysis, it emerged that most cases were reported from India. The mean age at time of diagnosis of the disease was 11 years, ranging from 3 to 17 years. The most frequent pattern was the reticular pattern followed by plaque-like, erosive, atrophic, sclerosus, and bullous. The buccal mucosa was the most involved oral site, followed by the tongue, lips and gingiva.
CONCLUSIONS
Although Oral Lichen Planus in children is rare, it may cause oral discomfort and need to be differentiated from other oral white lesions and/or chronic ulcers.

UNLABELLED
Epidermolysis bullosa hereditaria (EBH) is a group of rare diseases characterized by a cutaneous-mucosal fragility with the formation of bullae, including the oral mucosa. Therapeutic choices, especially prosthetic rehabilitation, must anticipate the worsening of the limitation of oral opening while respecting the functional and aesthetic expectations of the patients. This review on the oral prosthetic rehabilitation of patients with epidermolysis bullosa hereditaria (EBH) to study the level of evidence and quality of the presented available articles and establish clinical recommendations for the prosthetic management of these patients.
MATERIALS AND METHODS
An electronic search was done in July 2022 in five databases following PICOTS elements. The quality of the reports was established using the modified Pierson, Bradford Hills, and Ottawa Newcastle scale.
RESULTS
Data extracted from 19 case reports for protocolized analysis corresponded to 64 patients and 80 dental prostheses with almost 9 out of 10 patients being completely edentulous. The distribution of EBH types was 84% dystrophic, 10.5% junctional, and 5.5% simplex. The difficulties encountered by the authors synthetized in this review characteristically reflected those most likely encountered in dental practice. Most rehabilitations were implant-supported prostheses (85%) followed by removable dentures (10%) and finally dental-supported rehabilitations (5%). Fixed full-arch implant-supported prostheses represented 76.4% of implant-supported prostheses and this last prosthetic solution described showed the highest scientific quality.
CONCLUSIONS
In an individualized approach to treatment, we recommend that in cases of total edentulism, fixed full arch implant-supported prostheses are the most appropriate, as they allow the best computer-aided planning, design, manufacture, and fitting of the prosthesis in such a complex clinical context.

BACKGROUND
Chitosan is a cheap, accessible, nontoxic, biocompatible, and biodegradable compound. Also, this polysaccharide possesses antibacterial and anti-inflammatory properties. Consequently, a wide range of chitosan applications in the dentistry field has been explored. This work aimed to conduct a systematic review to address the clinical efficacy of chitosan for the treatment of oral mucositis.
MATERIAL AND METHODS
The design of the included studies were observational studies, randomized clinical trials (RCT), and non-randomized clinical trials (non-RCT), whereas, a series of cases, in vivo, and in vitro studies were excluded. The search was performed in PubMed, Web of Science, Scopus, Dentistry and Oral Sciences Source, and ClinicalTrials. Gray literature was searched at Google Scholar. Relevant data from all included studies were recorded. The risk of bias (using RoB 2) and the quality (using Grading of Recommendations Assessment, Development, and Evaluation, GRADE) assessments were carried out.
RESULTS
From the 8413 records screened, 5 clinical trials fully met the eligibility criteria, which comprised a total of 192 participants suffering oral lesions and pain related to oral mucositis. 100% of the included studies exhibited a high risk of bias. The quality of the studies was between low and very low.
CONCLUSIONS
The results of the included studies suggest that chitosan can diminish pain and improve the healing of ulcers in oral mucositis. However, there is no conclusive evidence of chitosan as a superior treatment for oral mucositis compared with other current therapies.

Review
BACKGROUND
Intraoral adenoid cystic carcinoma (ACC) arising from minor salivary glands (MSG) is a rare malignancy associated with delayed diagnosis and unfavorable outcomes. This study aimed to comprehensively review ACC of MSGs, focusing on clinical characteristics, imaging modalities, treatment approaches, and long-term outcomes.
METHODS
A systematic search was conducted in PubMed, Web of Science, and MEDLINE databases to identify relevant articles reporting cases of ACC of MSGs between January 1997 and March 2023. The study was registered in PROSPERO (ID: CRD42023449478). A total of 10 studies that met the inclusion criteria were selected for critical review. In total, 902 patients were diagnosed with ACC of MSGs with an age range of 44.3 to 63 years, and an average age of 56.6 years. The female to male ratio ranges from 1:1 to 2.4:1. Regarding the primary site of ACC, the palate was the most common location, accounting for 30.5% to 83.3%, followed by the buccal mucosa, floor of the mouth, and lip and the retromolar area. For histology, the solid mass pattern was the most prevalent, seen in 95.2% of patients, followed by the cribriform pattern. Regarding treatment modalities, surgery was the most common approach, applied in 76.3% of cases, with a combination of surgery and radiotherapy used in 29.0% of cases. A smaller fraction, 3.2%, received a combination of surgery, chemotherapy, and radiotherapy, and 8.3% underwent radiotherapy alone. Local recurrence rates varied between 1% and 28.5%, and distant metastasis occurred in 18.2% to 33.3% of cases, predominantly to lymph nodes (14.5%). An analysis of overall survival across various stages and patient numbers indicated a 5-year survival rate of 68.0%. The findings of this study provide valuable insights for physicians in making treatment decisions and emphasize the need for ongoing research and collaborative clinical efforts to improve the management and outcomes of this challenging disease.
CONCLUSION
ACC of MSGs is a multifaceted condition typically manifesting as asymptomatic enlargement and ulceration. This disease is marked by distinct histopathological patterns and perineural invasion (PNI). Recognizing these distinctive aspects is key in shaping the treatment plan, which can range from surgical procedures to radiation therapy, chemotherapy, and evolving targeted treatments. Continuous research and collaborative clinical efforts remain critical for ongoing progress in the treatment and management of this challenging condition.

Diagnostic accuracy of artificial intelligence assisted clinical imaging in the detection of oral potentially malignant disorders and oral cancer: A systematic review and meta-analysis.
BACKGROUND
The objective of this study is to examine the application of AI algorithms in detecting OPMD and oral cancerous lesions, and to evaluate the accuracy variations among different imaging tools employed in these diagnostic processes.
MATERIALS AND METHODS
A systematic search was conducted in four databases: Embase, Web of Science, PubMed, and Scopus. The inclusion criteria included studies using machine learning algorithms to provide diagnostic information on specific oral lesions, prospective or retrospective design, and inclusion of OPMD. Sensitivity and specificity analyses were also required. Forest plots were generated to display overall diagnostic odds ratio (DOR), sensitivity, specificity, negative predictive values, and summary receiver operating characteristic (SROC) curves. Meta-regression analysis was conducted to examine potential differences among different imaging tools.
RESULTS
The overall DOR for AI-based screening of OPMD and oral mucosal cancerous lesions from normal mucosa was 68.438 (95%CI= [39.484, 118.623], I2 = 86%). The area under the SROC curve was 0.938, indicating excellent diagnostic performance. AI-assisted screening showed a sensitivity of 89.9% (95%CI= [0.866,0.925]; I2 = 81%), specificity of 89.2% (95%CI= [0.851,0.922], I2 = 79%), and a high negative predictive value of 89.5% (95%CI= [0.851; 0.927], I2 = 96%). Meta-regression analysis revealed no significant difference among the three image tools. After generating a GOSH plot, the DOR was calculated to be 49.30, and the area under the SROC curve was 0.877. Additionally, sensitivity, specificity, and negative predictive value were 90.5% (95%CI [0.873,0.929], I2=4%), 87.0% (95%CI [0.813,0.912], I2=49%) and 90.1% (95%CI [0.860,0.931], I2=57%), respectively. Subgroup analysis showed that clinical photography had the highest diagnostic accuracy.
CONCLUSIONS
AI-based detection using clinical photography shows a high diagnostic odds ratio and is easily accessible in the current era with billions of phone subscribers globally. This indicates that there is significant potential for AI to enhance the diagnostic capabilities of general practitioners to the level of specialists by utilizing clinical photographs, without the need for expensive specialized imaging equipment.
