RESUMO
OBJECTIVE: The aim of this study was to assess the quality of free-to-access videos on oral biopsy procedures on the YouTube platform. MATERIALS AND METHODS: We conducted a search on YouTube using the term "oral biopsy" and selected the first 100 videos in order of relevance. The following exclusion criteria were applied: language other than English, videos that did not cover oral biopsy techniques, videos on nonhuman specimens, postoperative instructions, personal experiences, exfoliative cytology, or "brush biopsy." Forty-seven selected videos were classified based on their duration, country of origin, date of upload to the system, author, information source and number of views, and likes and dislikes. Video quality was analyzed using DISCERN, the Global Quality Scale (GQS), and the Video Information and Quality Index (VIQI). RESULTS: The majority (78.7%) of analyzed videos were uploaded by dentists, originating from India (48.9%), with a mean duration of 11.8 min (SD, 20.4), with 104.5 likes (SD, 186.4) and 7.1 dislikes (SD, 10.55). The mean values for DISCERN, GQS, and VIQI were 1.3 (SD, 0.52), 2.1 (SD, 1.04), and 9.62 (SD, 1.69), respectively. CONCLUSION: The majority of videos on oral biopsy published on YouTube are of low quality.
RESUMO
INTRODUCTION: Oral lichen is a chronic inflammatory disease for which diagnostic management and follow-up are heterogeneous given the absence of specific guidelines in France. Our objective was to develop French multidisciplinary guidelines for the management of oral lichen. MATERIALS AND METHODS: Working groups from the Groupe d'Etude de la Muqueuse Buccale (GEMUB) formulated a list of research questions and the corresponding recommendations according to the "formal consensus" method for developing practice guidelines. These recommendations were submitted to a group of experts and the degree of agreement for each recommendation was assessed by a scoring group. RESULTS: Twenty-two research questions, divided into 3 themes (nosological classification and initial assessment, induced oral lichenoid lesions, and follow-up) resulted in 22 recommendations. Initial biopsy for histology is recommended in the absence of reticulated lesions. Biopsy for direct immunofluorescence is recommended for ulcerated, erosive, bullous types and for diffuse erythematous gingivitis. Management should include a periodontal and dental check-up, and investigation for extra-oral lesions. Hepatitis C testing is recommended only if risk factors are present. Definitions, triggering factors and the management of "induced oral lichenoid lesions" were clarified. Oral lichen must be monitored by a practitioner familiar with the disease at least once a year, using objective tools. CONCLUSION: This formalised consensus of multidisciplinary experts provides clinical practice guidelines on the management and monitoring of oral lichen.

BACKGROUND: Although superpotent topical corticosteroids are the first-line treatment for oral erosive lichen planus (OELP), topical rapamycin was found efficient in a previous case series. OBJECTIVES: To compare the efficacy and safety of topical rapamycin and betamethasone dipropionate ointment for OELP in a randomized, double-blind trial. METHODS: Patients were randomized to receive treatment with betamethasone dipropionate ointment 0.05% in Orabase® or topical rapamycin solution (1 mg/mL) on lesions twice daily for 3 months, followed by 3 months of observation. The primary outcome was clinical remission after 3 months of treatment. Secondary outcomes were clinical remission after 1 and 2 months, reduced oral pain and reduced impact on food intake after 3 months, clinical recurrence after treatment withdrawal, and adverse events. RESULTS: During a 4-year period, 76 patients were randomized and 75 received treatment (rapamycin, n = 39; betamethasone, n = 36). At 3 months, 39.4% of patients with betamethasone and 27.3% with rapamycin showed clinical remission (odds ratio 0.68, 95% CI [0.24; 1.89]; P = 0.46). Rates of remission after 1 and 2 months, reduction in pain and impact on food intake after 3 months, were higher with betamethasone than rapamycin. Recurrence of oral erosions was similar between groups. Adverse events occurred in 43.6% of patients with rapamycin (mostly burning sensation, impaired taste) and 27.8% with betamethasone (mostly oral candidiasis). CONCLUSION: Although the study was limited by insufficient recruitment, we did not find any superiority of topical rapamycin over betamethasone dipropionate ointment for OELP. Given the rapid remission and pain improvement in the betamethasone group, it appears that superpotent topical corticosteroids should remain the first-line treatment for OELP.

BACKGROUND: Older persons comprise a growing proportion of the European population and may have a distinct epidemiological oral profile requiring specific preventive and curative care poorly documented. The objectives of this study were to assess the oral health status of people ≥90 years of age in France, to compare their perceived and observed oral care needs and to investigate the oral problems associated with a low oral health-related quality-of-life (OHRQoL). METHODS: An oral cross-sectional study was performed during the 25th follow-up of a cohort of older persons being followed up prospectively for screening of dementia over a 15-year period in Gironde and Dordogne, France. Clinical oral indices were determined by oral examinations conducted at the participants' place of living. Cohen's Kappa coefficient was used to assess the agreement between perceived and observed oral care needs. Oral problems associated with a low OHRQoL, measured with the Geriatric Oral Health Assessment Index (GOHAI<50) were investigated with logistic regression. Odds ratios (OR) were estimated with their 95% confidence intervals (CI). RESULTS: Data from 90 persons were analysed (76% female; median age=93 years; 20% living in an institution). Plaque and calculus were present in 93% and 58% respectively, of the 74 dentate participants. The mean number of decayed, missing, and filled teeth was 26.5 (±5.3); 66% of the participants had at least one untreated decayed tooth. Among the 85 participants with tooth loss not replaced by a fixed denture, two thirds had a removable dental prosthesis; 84% of these prostheses were considered to be maladapted. Among the 39 participants who felt unable to consult a dentist (43%), lack of transportation was the most frequently cited reason. Although 88% of the participants needed oral care, only 26% perceived that they had such a need (Kappa=0.06). Oral problems associated with a GOHAI<50 were the absence of posterior occluding teeth (OR=7.15; 95%CI=1.53-33.35; P=0.012), feeling of dry mouth (OR=11.94; 95%CI=3.21-44.39; P=0.0002) and oral pain (OR=9.06; 95%CI=1.91-69.00; P=0.033). CONCLUSIONS: Persons ≥90 years of age have considerable preventive and curative dental care needs that impact their quality-of-life but they are rarely aware and lack transportation. NCT04065828.

OBJECTIVES: Since its first use for the reconstruction of tissue defects in the oral cavity in 1985, human amniotic membrane (hAM) has been widely studied in the field of oral surgery. Despite the growing number of publications in this field, there is no systematic review or meta-analysis concerning its clinical applications, outcome assessments, and relevance in oral surgery. The aim of this review is to provide a thorough understanding of the potential use of hAM for soft and hard tissue reconstruction in the oral cavity. MATERIALS AND METHODS: A systematic electronic and a manual literature search of the MEDLINE-PubMed database and Scopus database was completed. Patient, Intervention, Comparison and Outcomes (PICO) technique was used to select the relevant articles to meet the objective. Studies using hAM for oral reconstruction, and conducted on human subjects, were included in this survey. RESULTS: A total of 17 articles were analyzed. Five areas of interest were identified as potential clinical application: periodontal surgery, cleft palate and tumor reconstruction, prosthodontics and peri-implant surgery. Overall, periodontal surgery was the only discipline to assess the efficacy of hAM with randomized clinical trials. The wide variability of preservation methods of hAM and the lack of objective measurements were observed in this study. CONCLUSION: hAM is already used in the field of oral surgery. Despite this, there is weak clinical evidence demonstrating convincingly the benefit of hAM in this area compared to standard surgery. CLINICAL RELEVANCE: Several studies now suggest the interest of hAM for periodontal tissue repair. Due to its biological and mechanical properties, hAM seems to be a promising treatment for wound healing in various areas of oral reconstruction. However, further randomized clinical trials are needed to confirm these preliminary results.

BACKGROUND: Oral cancer is a public health issue worldwide. Oral potentially malignant disorders (OMPDs) are lesions of the oral mucosa that are predisposed to malignant transformation. The mainstay of OMPDs treatment around the world is now the carbon dioxide (CO2) laser but the reported recurrence and malignant transformation rates vary widely in the literature. We aimed to estimate the recurrence and the malignant transformation rates of OPMDs treated with CO2 laser at the University Hospital of Bordeaux, in France, from 2010 to 2014, and to identify associated factors with recurrence or malignant transformation. MATERIAL AND METHODS: We conducted a retrospective study in patients with a minimum follow-up of 12 months. Collected variables included characteristics of the patients (gender, age, alcohol and tobacco consumption, previous diagnosis of graft-versus-host disease, previous treatments for OPMD or for upper aerodigestive tract cancers and human immunodeficiency virus infection), characteristics of the lesions (form, colour, size, location, degree of dysplasia), laser treatment outcome (complications, recurrence, malignant transformation). RESULTS: Twenty-five patients were included. Mean follow-up was 28.9 months. Recurrence was observed in 11 patients (44%). Annual recurrence rate was 18.3% and annual malignant transformation rate was 1.7%. Hyperplasia without dysplasia was the only factor found to be statistically associated with recurrence. CONCLUSIONS: Our results suggest that OMPDs treated by CO2 laser vaporization have high recurrence rates, particularly those presenting hyperplasia. A standardized definition of recurrence would be necessary for inter-study comparisons. Long-term follow-up is recommended in order to detect and treat squamous cell carcinoma in its early stages.

BACKGROUND: Regular cannabis use may be associated with several oral changes not usually identified by dermatologists: xerostomia, increased risk of caries, periodontitis, leukoedema, gingival hyperplasia, and higher prevalence and density of Candida albicans, leukoplakia or gingivitis. PATIENTS AND METHODS: We report herein the appearance of a characteristic green tongue in a patient following intensive marijuana inhalation. DISCUSSION: This complication has rarely been reported in the medical literature. Paradoxically, it is clearly described in different Internet search engines, particularly Google.

AIM: To develop a biological scaffold that could be moulded to reproduce the geometry of a gutta-percha point with precision and allow the differentiation of mesenchymal stem cells into osteoblasts to be used as a regenerative endodontic material. METHODOLOGY: A collagen/alginate composite scaffold was cast into a sodium alginate mould to produce a gutta-percha point-like cone. Prior to gelation, the cone was seeded with human stem cells from the apical papilla (SCAPs) to evaluate cell/scaffold interactions. The reconstructed tissue was characterized after 8 days in culture. Elastic modulus, tissue compaction and cell differentiation were assessed. Student t-tests and the Mann-Whitney U test were performed. RESULTS: The fabrication method developed enabled the shape of a gutta-percha point to be mimicked with great accuracy and reproducibility (P = 0.31). Stem cells seeded into this composite scaffold were able to spread, survive and proliferate (P < 0.001). Moreover, they were able to differentiate into osteoblasts and produce calcified osseous extracellular matrix (P < 0.001). The construct showed no significant contraction after 8 days, preserving its shape and tip diameter (P = 0.58). CONCLUSIONS: The composite scaffold could present substantial benefits compared to synthetic materials. It could provide a favourable healing environment in the root canal conducive for regenerative endodontics and is therefore appropriate to be evaluated in vivo in further studies.

BACKGROUND: Oral hairy leukoplakia (OHL) is an EBV-associated condition of the oral mucosa, which is often painless. It is found predominantly in HIV-positive patients and is considered a clinical indicator of immunosuppression. OHL has rarely been described in HIV-negative patients, being found most often in association with iatrogenic immunosuppression. OHL induced by topical steroids remains extremely rare. PATIENTS AND METHODS: An 81-year-old HIV-negative woman, treated for 3 months with topical steroids for oral lichen planus, developed an asymptomatic white, corrugated, non-removable plaque with vertical folds on the lateral edge of the tongue. Associated oral candidiasis was noted. Based upon histological findings and in situ hybridisation showing numerous EBV-infected epithelial cells, a diagnosis of oral hairy leucoplakia was made. DISCUSSION AND CONCLUSION: To our knowledge, we report herein only the second recorded case of OHL induced strictly by topical steroids. Self-medication and poor adherence to dosage recommendations were noted in the patient's medical history. Physicians must be aware of the rare but nevertheless possible adverse events associated with topical steroid use, particularly when such medication is prescribed over a long period for inflammatory diseases of the oral mucosa.

While toxicity of targeted anticancer therapies on the oral mucosa seems relatively frequent in clinical practice, it has not been properly characterized to date, apart from aphthous-like lesions due to mTOR inhibitors. Herein, we report the main oral lesions associated with these new therapies, with a description of the most frequent but also the most characteristic clinical manifestations of these drugs, such as anti-EGFR-induced mucositis, BRAF-inhibitor-associated hyperkeratosis, benign migratory glossitis and osteonecrosis of the jaw observed with angiogenesis inhibitors, as well as lesions more specifically linked with imatinib.

The occurrence of hyperpigmentation during chemotherapy is one of the most frequent dermatological adverse events observed with these drugs. It may arise with numerous anticancer agents, and can be either localized or diffuse, occurring either immediately or after inflammatory dermatological lesions. Nails, mucosa and skin may all be affected. Though the incidence is high in clinical practice, such drug-induced hyperpigmentation has been only rarely individualized and characterized. Herein we describe the main clinical, histological and pathophysiological characteristics of these lesions and the most frequently incriminated chemotherapeutic agents, as well as the anatomical areas involved and the most specific clinical patterns such as flagellate dermatitis, reticulate or serpentine supravenous hyperpigmentation and eruptive naevi.

INTRODUCTION: Riga-Fede disease is a benign affection of the oral mucosa which has been poorly described in the literature. This entity of unknown ethiopathogenicity is sometimes revealing of dysautonomic or neuropsychic disorders. We report a new case. CASE REPORT: A 10-month-old girl was referred to us for a unique deep ulceration of the lower lingual apex, in a context of right basal pneumopathy. Samples were negative for bacteriological, virological and mycological analysis. After successful treatment of the pneumopathy, the ulceration was unchanged and we diagnosed Riga-Fede disease. DISCUSSION: Our observation is representative of the Riga-Fede cases previously described in the literature, comparing the age of onset, the topography and the ulceration type. We did not diagnose any dysautonomic or neuropsychic disorder as reported in some cases. Suppression of the lingual trauma resulted in healing of the ulceration.

Maxillofacial defects reconstruction represents a formidable challenge to achieve both functional and aesthetic goals. To succeed, numerous parameters must be taken into account: patient's general conditions, defect's location, width and type of the defect and eventual donor sites which can provide the tissues. Routine reconstructions include bone transplantation (autologous, homologous or heterologous), implantation of biomaterials and osteogenic distraction. The advantages of these techniques are evident, but they are usually limited by their complexity in patients with bad general health. The technique of induced membranes needs to be more known in maxillofacial surgery.

For bone tissue engineering, human Adipose Derived Stem Cells (hADSCs) are proposed to be associated with a scaffold for promoting bone regeneration. After implantation, cellularised scaffolds require a non-invasive method for monitoring their fate in vivo. The purpose of this study was to use Magnetic Resonance Imaging (MRI)-based tracking of these cells, labelled with magnetic agents for in vivo longitudinal assessment. hADSCs were isolated from adipose tissue and labelled with USPIO-rhodamine (Ultrasmall SuperParamagnetic Iron Oxide). USPIO internalisation, absence of toxicity towards hADSCs, and osteogenic differentiation of the labelled cells were evaluated in standard culture conditions. Labelled cells were then seeded within a 3D porous polysaccharide-based scaffold and imaged in vitro using fluorescence microscopy and MRI. Cellularised scaffolds were implanted subcutaneously in nude mice and MRI analyses were performed from 1 to 28 d after implantation. In vitro, no effect of USPIO labelling on cell viability and osteogenic differentiation was found. USPIO were efficiently internalised by hADSCs and generated a high T2* contrast. In vivo MRI revealed that hADSCs remain detectable until 28 d after implantation and could migrate from the scaffold and colonise the area around it. These data suggested that this scaffold might behave as a cell carrier capable of both holding a cell fraction and delivering cells to the site of implantation. In addition, the present findings evidenced that MRI is a reliable technique to validate cell-seeding procedures in 3D porous scaffolds, and to assess the fate of hADSCs transplanted in vivo.

INTRODUCTION: The sensitivity of visual examination for the diagnosis of oral cancers is estimated at 85% and its specificity at 97%. However, it is likely that numerous lesions remain undetected. The objective of this article was to review literature on the contribution of tissular autofluorescence to detect potentially malignant and malignant lesions of the oral cavity. MATERIAL AND METHOD: The Medline database was consulted using the following keywords: fluorescence and cancer; autofluorescence and cancer; fluorescence and oral cancer; autofluorescence and oral cancer; Velscope(®) and oral cancer. Only original articles and clinical case reports on the oral cavity published in English since 1999 were considered. RESULTS: Twenty-three publications were analyzed. Twelve studies concerned spectroscopy and 14 direct autofluorescence. The specificity of AF ranged between 75 and 100% in spectroscopy and between 39 and 100% in direct vision. The sensibility of the AF varied between 78 and 100% in spectroscopy and between 50 and 100% in direct vision. DISCUSSION: The variability of results may be explained by selection bias. The main contribution of fluorescence is to highlight oral mucous membrane lesions and to help physicians to better locate them. The lack of AF specificity supports the contribution of histological examination which remains the reference examination for the diagnosis of potentially malignant lesions and cancers of the oral cavity.
