Systematic review of benefits and practical challenges for application of Mohs surgery for oral tumors

Mohs micrographic surgery (MMS) may be an effective treatment modality for oral cavity cancers (OCC) due to possibility of more effective visualization of tumor margins and greater preservation of benign tissue. The objective of this study is to review the existing literature on the use of MMS for the treatment of OCC and categorize its uses and limitations. A systematic review was performed in accordance with Assessing the Methodological Quality of Systematic Reviews (AMSTAR) guidelines. PubMed, Scopus, and Google Scholar from inception of databases to January 20, 2023 identified all published studies on the use of MMS for OCC. Nine studies met inclusion criteria. Seventy-seven patients were treated with MMS for OCC, 74 of which (96%) were treated for squamous cell carcinoma (SCC). The tongue was the most common site (n = 57). Six out of seven studies showed no recurrence of disease during the follow-up periods, which ranged from 8 to 42 months, and one study reported significantly lower loco-regional recurrence over a 2-years follow-up period (10.5% vs 25.7%). Mohs technique did not cause a statistically significant increase in operating time. Applicability of MMS is limited by operator comfort with surgical technique and pathological interpretation of specimens in the oral cavity. The main limitation was that various studies did not report specific patient characteristics. In conclusion, MMS may be an effective treatment for OCC, especially for squamous cell carcinomas, and tumors involving the tongue.

Improvement of Mucosal Lesion Diagnosis with Machine Learning Based on Medical and Semiological Data: An Observational Study

Despite artificial intelligence used in skin dermatology diagnosis is booming, application in oral pathology remains to be developed. Early diagnosis and therefore early management, remain key points in the successful management of oral mucosa cancers. The objective was to develop and evaluate a machine learning algorithm that allows the prediction of oral mucosa lesions diagnosis. This cohort study included patients followed between January 2015 and December 2020 in the oral mucosal pathology consultation of the Toulouse University Hospital. Photographs and demographic and medical data were collected from each patient to constitute clinical cases. A machine learning model was then developed and optimized and compared to 5 models classically used in the field. A total of 299 patients representing 1242 records of oral mucosa lesions were used to train and evaluate machine learning models. Our model reached a mean accuracy of 0.84 for diagnostic prediction. The specificity and sensitivity range from 0.89 to 1.00 and 0.72 to 0.92, respectively. The other models were proven to be less efficient in performing this task. These results suggest the utility of machine learning-based tools in diagnosing oral mucosal lesions with high accuracy. Moreover, the results of this study confirm that the consideration of clinical data and medical history, in addition to the lesion itself, appears to play an important role.

Knowledge about oral manifestations of systemic diseases among medical and dental students from Jordan: An interdisciplinary educational gap

OBJECTIVE

To assess the ability of medical students to recognize oral manifestation of selected systemic diseases and compare their performance with dental students.

MATERIALS AND METHODS

A total of 400 senior medical and dental students were approached to participate. The study protocol involved two parts; a self-administered survey and a direct interview involving clinical photographs for oral signs of systemic diseases.

RESULTS

A total of 283 (70.8%) agreed to participate and completed the two- part study. The study population was made of 110 (38.9%) [82 females and 28 males] dental students, and 173(61.1%) [98 females and 75 males] medical students. The knowledge score regarding questions about the normal mouth and oral structures was 15.7 ± 6 out of 22. Dental students had a significantly higher knowledge score about normal mouth and oral structures (20.9 ± 4; range from 17 to 22) compared to medical students (10.6 ± 7; range from 4 to 21) (p = .029). The knowledge score regarding questions about oral manifestations of systemic diseases was 26.8 ± 6 out of 40. Dental students had a significantly higher knowledge score about oral manifestations of systemic diseases (30.8 ± 7; range from 15 to 37) compared to medical students (22.9 ± 4; range from 10 to 36) (p = .031). Only 24.3% (n = 42) medical students reported having adequate training to be able to distinguish between normal mouth and diseases. Nearly all medical students (91.3%; n = 158) felt that it is important to have more formal training in oral examination and disease diagnosis.

CONCLUSION

Medical students lack adequate knowledge, diagnostic ability, and confidence with regard to diagnosis of oral signs of systemic diseases. To ensure that medical students have necessary skills in assessing oral diseases, curricula revisions and modifications are required, and specific oral health-related learning outcomes should be introduced and reinforced through clinical training.

Medical practitioners' educational competence about oral and oropharyngeal carcinoma: a systematic review and meta-analysis

Medical practitioners' (MP) role is pivotal in primary prevention, early diagnosis, prompt referral and effective management of oral and oropharyngeal carcinomas (OC/OPC), which raises the importance of their effective OC/OPC education at all levels of medical education. The purpose of this systematic review was to summarise the available scientific evidence about their educational competence in dealing with OC/OPC. We made a systematic search of papers in the English language in MEDLINE, Scopus, Cochrane Library CENTRAL and CINAHL databases from their inception until December 2018. Overall, 23 cross-sectional and three interventional studies have been selected for the systematic review and 18 of these were included in the meta-analyses. Excluding tobacco use (synthesised estimate of 95% of respondents identified tobacco as an OC/OPC risk factor, 95% CI of synthesised estimate 92% to 97%) and alcohol consumption (65%, 95%CI 52% to 77%), less than half of MP (approximately) were knowledgeable about important OC/OPC risk factors including human papilloma virus (42%, 95% CI 30% to 54%), poor diet (34%, 95% CI 17% to 54%), and advancing age (45%, 95% CI 21% to 70%). There was a low to moderate level of awareness among MP regarding common precancerous oral lesions involving leukoplakia (56%, 95% CI 32% to 79%), erythroplakia (30%, 95% CI 8% to 58%), and oral lichen planus (13%, 95% CI 0 to 41%). Moderate knowledge was also recorded about frequent sites of OC development involving the tongue (48%, 95% CI 33% to 64%) and floor of the mouth (37%, 95% CI 19% to 57%). Most MP enquired about tobacco use (86%, 95% CI 74% to 96%), and alcohol consumption (73%, 95% CI 47% to 94%) during history taking, and expressed willingness to be given supplementary OC/OPC education (78%, 95% CI 54% to 96%), as well. With regard to the incidence of intraoral screening, 27% of MP (95% CI 12% to 46%) make an intraoral examination as a routine. Interestingly, studies from each continent yielded significantly different outcomes to some research questions in the review. From the MP's perspective, clinical time restrictions and deficiencies in organised training were recognised as the main barriers towards their OC/OPC educational competence. The findings of this systematic review indicated the existence of deficiencies in knowledge and misconceptions, neglected preventive responsibilities, and associated barriers towards OC/OPC. A need for improved OC/OPC training at all levels of medical education is required to increase competence worldwide.

Knowledge and practices of dentists in France regarding oral mucosal diseases: a national survey

Introduction:One of the dental surgeon's roles is to identify, diagnose and supervise the treatment of oral pathologies (OP), and/or to refer patients to the appropriate specialists. Today, the delay in diagnosing patients with OP is very long and may impact their prognosis.Objective:We conducted a national survey of French practitioners to estimate their knowledge and practices regarding the management of these pathologies.Methods:About 15,000 dentists were contacted by email to complete a questionnaire designed to assess the diagnoses and management of OP.Results:Overall, for 560 answers (3.8%), DS did not declare any significant difficulties in diagnosing and managing any kind of pathologies. However, we were able to distinguish statistical differences among practitioners depending on the type of lesions and between the practitioners themselves. The associated factors were gender, graduation year, mode of practice and continuing education over the last 5 years. The majority of DS justified their diagnostic difficulties by the fact that they do not encounter patients with these types of pathology frequently enough, and by insufficient education.Conclusion:According to our study, it is necessary to reinforce the training and the continuing medical education of DS regarding OP, especially through the use of practical cases.

Awareness of oral medicine among medical practitioners, evidence of the unbridged interdisciplinary gap

RATIONALE, AIMS, AND OBJECTIVES

Inadequate awareness of oral health and related disciplines appears to be common among medical practitioners. This study was designed to evaluate the awareness of oral medicine (OM) specialty and its scope of practice among Jordanian medical practitioners and to outline potential strategies for improvement where appropriate.

METHOD

A specially designed questionnaire was electronically distributed to Jordanian medical practitioners and thereafter via personal interviews to improve the response rate. The questionnaire comprised nine questions and covered demographical details and characteristics of participants, in addition to their awareness of OM and agreement to refer a group of common oral and dental conditions to OM specialists. Pearson Chi-square tests were used to examine the significance of association between the variables of respondents and awareness of OM. Significance level was set at P values < 0.05.

RESULTS

A total of 1492 respondents completed the questionnaire, of which 779 (52.2%) were aware of OM as an independent specialty. Age group, higher degrees in medicine, country of graduation, and the specialty type were significant determinants of OM awareness level. Oral ulceration and other mucosal pathology, including fungal infections, were the most likely conditions to be referred to OM specialists while participants had apparent problems separating the scope of practice of OM from other dental disciplines.

CONCLUSION

This study provides evidence on the profound interdisciplinary gap between medicine and dentistry and highlights the importance of more focused education and training in oral health-related disciplines to be provided to clinicians and medical trainees as described.
