Abstract
Oral Potentially Malignant Disorder (OPMD) is a significant concern for clinicians due to the risk of malignant transformation. Oral Squamous Cell Carcinoma (OSCC) is a common type of cancer with a low survival rate, causing over 200,000 new cases globally each year. Despite advancements in diagnosis and treatment, the five-year survival rate for OSCC patients remains under 50%. Early diagnosis can greatly improve the chances of survival. Therefore, understanding the development and transformation of OSCC and developing new diagnostic methods is crucial. The field of oral medicine has been advanced by technological and molecular innovations, leading to the integration of new medical technologies into dental practice. This study aims to outline the potential role of non-invasive imaging techniques and molecular signatures for the early detection of Oral Malignant and Potentially Malignant Disorders.

Abstract
Objective: Assess trace elements in betel leaves and slaked lime from different regions of Karnataka, India using Laser Induced Breakdown Spectroscopy (LIBS). Materials and Method: Betel leaves from six different regions of Karnataka were obtained and named (for the purpose of the study) BL1, BL2, BL3, BL4, BL5, and BL6 and they were sun-dried. A single tube of slaked lime was obtained from the local ‘paan’ shop. Each dried leaf and a single blob of slaked lime was subjected to elemental analysis using Laser-induced breakdown spectroscopy. Results: A ten-trial experiment was carried out in all six leaves and a blob of the slaked lime. The National Institute of Standards and Technology (NIST) database was used to assess the emission lines. The elements that were predominantly present in all six betel leaves from different regions of Karnataka are calcium, copper, and iron. Slaked lime showed only the presence of calcium. Conclusion: It is widely accepted that the consumption of betel quid causes various changes in the oral mucosa including oral potentially malignant disorders (OPMDs) and oral cancer. It is important to analyze each component of betel quid to understand the disease progression. Copper is found to be relatively higher in betel leaves, and it is known that copper-induced fibrogenesis via the lysyl oxidase pathway in oral submucous fibrosis.

Abstract
OBJECTIVES This study aimed to assess the impact of Continuing Education (CE) activity on junior dentists' competency to identify oral mucosal abnormalities those suggestive of oral cancer or potentially malignant disorders. MATERIALS AND METHODS This multiphase study administered a pre-validated quiz to dental interns and junior dentists. The quiz was designed to assess the respondent's competency to recognize different oral lesions and stratify their potential for malignancy. Invited candidates attempted the quiz and then attended an informative half-day workshop focused on identifying oral mucosal changes, diagnosing various oral lesions, and recognizing the risk factors and features that suggest the malignant potential of oral lesions. The post-intervention survey was sent to the workshop attendees by 7 months. RESULTS 67 out of 110 invitees attended the workshop, with an overall response rate of 60.1%. In the initial quiz, the overall accuracy of diagnosis was 55.1±9.04%. The participants correctly identified most normal variations (80.60±5.05), but less than half of the benign lesions (40.96±8.30) and potentially malignant lesions (43.62±6.02). The malignant lesions were correctly diagnosed by 55.22±3.98% of the participants. The CE intervention has improved the overall diagnostic accuracy (74.81±5.84% (p,0.015); benign to 70.18±6.68% (p,0.02), the potentially malignant lesions to 62.99±4.63% (p,0.01). CONCLUSIONS This study highlights the importance of CE activity in improving the role of dentists in the detection of oral cancer. CE activity has remarkably enhanced the junior dentists' ability to accurately diagnose various oral lesions and effectively stratify their malignant potential.

Abstract
Background The study aimed to investigate the association between socioeconomic status and severity of oral epithelial dysplasia (OED) using current data from the Taiwanese Nationwide Oral Mucosal Screening Program (TNOMSP).
Methods This retrospective analysis was conducted in the Department of Oral and Maxillofacial Surgery at a general hospital in Taipei, Taiwan. A total of 134 participants were analysed from a previous study database of 150 patients. The inclusion criteria included age > 20 years and a history of either tobacco or betel nut use. Background information, including para-habits such as betel and tobacco use, was analysed using the Pearson chi-square (χ2) test; furthermore, the correlation of background information with OED severity was investigated using logistic regression (mild or moderate/severe). Results High school education level (P < 0.001), poor self-awareness (P = 0.002), current betel use (P < 0.001), and tobacco use (P = 0.003) were highly correlated with moderate- and severe OED (P < 0.05). The odds ratio (OR) of education status above senior high school was 0.03 (95% confidence interval [CI] 0.01–0.15, P < 0.001), while that of junior high school was 1. Current betel chewing (OR 6.57 [95% CI 1.17–37.0], P = 0.033) was significantly associated with OED severity compared with never or ex-use of betel. Conclusions We found a strong correlation between the severity of OED and current betel use and low education status. The current study revealed that the socioeconomic status, poor self-awareness, and para-habit history of the patients with OED should be evaluated to identify high-risk individuals using TNOMSP.

Abstract
Backgound and Objective: Early chemoprevention in Oral Potentially Malignant Disorders (OPMDs) and Oral Cancer (OC) has been extensively researched in order to mitigate the malignant transformation and progression of the lesion. Many agents have been attempted, but their cost inefficacy and inadequate outcomes posed a major hindrance in their successful adoption. Retinoid Based Therapy (RBT) though a cheap and effective treatment option, could not achieve much clinical usage because of variable responsiveness in clinical outcomes. Such clinical response variability may be attributed to the repression of retinoid receptors by Preferentially Expressed Antigen of Melanoma (PRAME) protein molecule. Therefore, in order to make RBT successful, targeting PRAME by various immunotherapies is an exciting area of research investigation. This review provides an insight into the various immunotherapeutic strategies targeting PRAME and their usefulness in retinoid-resistant OPMD and OC. Method of data collection: An exhaustive internet-based literature search following PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines was carried out in PUBMED and Google SCHOLAR database using terms 'Anti-PRAME' OR 'PRAME Immunotherapy' OR 'PRAME Vaccines' AND 'Cancer' AND 'Retinoid resistance'. Only articles in the English language with at least 1 citation, published in a journal with impact factor ≥ 1, having relevance to the context and availability of full text were considered. Results: After an initial search, 342 articles were yielded on the basis of inclusion criteria and, by reading the abstract and availability of full text, a total of 124 articles were selected. Further reading the full texts and considering articles from the references of the selected articles, a total of 65 articles were finally included in the review. Conclusion: Our analysis of the literature suggests that PRAME screening in OC and OPMDs prior to RBT should be done. In PRAME positive cases, approaches like PRAME based immunotherapy in the form of Cancer vaccine therapy [Acellular PRAME vaccine, PRAME pulsed Dendritic Cells (DC)]; Adoptive T Cell therapy/T Cell Receptor-T Cell therapy, Antibody therapy/Chimeric Antigen Receptor-T Cell therapy along with Presented antigen modulation Therapies employing histone deacetylase inhibitors and demethylation agents seem plausible. In the future, a combination therapy employing either PRAME vaccines or antibodies or Adoptive T cell Therapy and ATRA could be used in retinoid resistant OC and OPMDs.

Abstract
Objectives: The main objectives of this study were to investigate the detection rate of high-risk human papillomavirus types 16 and 18 (high-risk HPV16/18) in oral potentially malignant disorders (OPMDs) including oral leukoplakia (OL) and oral lichen planus (OLP) in a Thai population and their associations with demographic, risk habits, and clinicopathologic features. Methods: Paraffin-embedded formalin-fixed specimens from 101 OL and 59 OLP patients with patients’ demographic, risk habits, and clinicopathologic data were collected. Conventional qualitative polymerase chain reaction was used to detect high-risk HPV16/18 DNA. Associations between high-risk HPV type 16/18 and demographic, clinicopathologic, risk factors (tobacco and alcohol uses) of OPMDs were analysed by Chi-square or Fisher’s exact test. The results with p value less than 0.05 were considered statistically significant. Results: HPV16/18 DNA was found in both OL and OLP groups with the detection rate of 19.8% and 18.6%, respectively. Approximately 90% of high-risk HPV were HPV18 subtype. Additionally, in OL group, high-risk HPV was found more frequently in patients with moderate/severe dysplasia than that in mild dysplasia. Interestingly, in OLP group, high-risk HPV was only detected in atrophic/ulcerative subtypes. None of risk factors was associated with high-risk HPV. Conclusions: Approximately 19% of OPMDs were HPV16/18-positive. HPV18 DNA was predominantly detected in both OL and OLP patients (90%). Additionally, the detection rate of high-risk HPV was higher in more severe dysplastic cases of OL and more clinically severe cases of OLP.

Abstract
OBJECTIVES Tokyo Dental College started oral cancer screening in cooperation with a local dental association in 1992. Reveal the usefulness of Countermeasure and Opportunistic Screening Systems for Oral Cancer. The actual results of countermeasure and opportunistic oral cancer screening systems are reported. MATERIALS AND METHODS Countermeasure screening for the public was performed in each region, and opportunistic screening was performed in a general dental clinic of a cooperating physician. RESULTS In countermeasure screening, 19,721 persons were checked from 1992 to 2018; the gender ratio was 1:3. The close examination rate was 4.45%. The detection rates of oral cancer and oral potentially malignant disorders were 0.13% and 1.85%, respectively. In opportunistic screening, 29,912 persons were checked from 2006 to 2018; the gender ratio was 2:3. The close examination rate was 2.33%. The detection rates of oral cancer and oral potentially malignant disorders were 0.08% and 2.15%, respectively. The close examination rate was significantly lower in opportunistic screening than in countermeasure screening. The oral cancer detection rates and the positive predictive value for cancer were equivalent. In addition, the detection rate of oral potentially malignant disorders was significantly higher in opportunistic screening than in countermeasure screening. CONCLUSION Oral cancer detection rates were equivalent between countermeasure and opportunistic screenings, and opportunistic screening were more effective on number of participants and the close examination rate, and the detection rate of oral potentially malignant disorders.

Abstract
PURPOSE The purpose is to determine the sufficient extension of margins during laser ablation of oral leukoplakia and observe its short-term recurrence rate. MATERIALS AND METHODS The study was designed as a randomized controlled clinical trial was conducted on 33 oral leukoplakia lesions diagnosed in 30 patients (16 Females and 14 Males) with an age range between 39 and 79 years. The lesions were divided into three groups; Group A: 11 lesions in 11 patients, in which the laser ablation was done for the entire lesion without extension of margins; Group B: 11 lesions in 8 patients, in which the laser ablation was done for the lesion adding at least 3mm extension of margins; and finally the Group Control: consists of 11 untreated lesions in 11 patients, in which only "wait and see" approach was done. RESULTS Complete healing of 13 lesions occurred in both groups A and B. Complete regression of 3 lesions occurred in Group Control. After 6 months of follow-up, 6 of 9 lesions in both groups A and B that showed the recurrence, had shown an initial recurrence after 3 weeks of the laser ablation. Patients with no history of smoking habits showed complete healing of 87.5%, while in ex-smokers complete healing was 42.8%. The statistical analysis was performed, and the averages of all groups are significantly different (p <0.00001). DISCUSSION The primary treatment focuses on the elimination of associated risk factors (smoking, alcohol, and local irritating factors). In the literature, the recurrence rate varies between 13.6% and 40.7%, while in our study, it was 45.5% in Group A and 36.4% in Group B. CONCLUSION The recommended extension of margins should be at least 3mm in width. Further research can be performed to evaluate the immediate re-ablation of the lesions which showed an initial recurrence after 3 weeks of laser ablation.
