The management of oral potentially malignant disorders (OPMD) including oral leukoplakia (OL) is not currently structured according to agreed guidelines. The current report presents survey data gathered from Oral Medicine Practitioners (OMPs) in Europe and Australia and is aimed to investigate attitudes and practice in the diagnosis, risk stratification and treatment of OL. In the presence of a clinical provisional diagnosis of OL, respondents reported always undertaking biopsy in 83% of cases, with most OMPs also relying on diagnostic adjuncts. The potential for malignant transformation is almost invariably assessed through epithelial dysplasia status, with other biomarkers described in the literature used less often. Active treatment of OL was considered mandatory by 20% of OMPs, while others reserve treatment for selected cases only. OMPs are mostly driven to active treatment by lesion‐related features which are frequently jointly considered including lesion site, clinical appearance and dysplasia status. Inconsistent assessment was observed regarding mild dysplasia, lesion size, presence of unavoidable trauma, exposure to tobacco and patient age. Frequently observed geographical variations were seldom statistically significant. In agreement with previous surveys, a lack of consensus around the management of OL was observed, supporting claims from learned academies and societies for treatment guidelines aiming to reduce inter‐practitioner variability.

Oral Medicine (OM) is a young dental specialty born almost a century ago in the United States treating patients with complex oral mucosal manifestations. Such demanding clinical conditions lead to the combination of knowledge in general medicine, dermatology and pathology to provide care to such patients (Shklar & McCarthy, 2008).Briefly, it could be stated that OM practice includes diagnosis and management of orofacial conditions not directly attributable to the most prevalent tooth-related pathologies such as dental caries or periodontal diseases. Presentations may reflect specific mouth disease or orofacial manifestations of systemic multifocal conditions.Nevertheless, the scope, definition and academic education vary significantly across the world (Bez et al., 2017;Scully et al., 2016). The field of Oral Medicine independently developed across the globe and the young age of this discipline, jointly with diversity of cultures and heterogeneity of global settings and healthcare systems, has led to differences in its practice (Bez et al., 2017;Scully et al., 2016).

Objectives Oral lichen planus with exclusive keratotic reticular, papular, and/or plaque-like lesions (K-OLP) is a clinical pattern of OLP that may be associated with a complex symptomatology and psychological alteration. The aim of the study was to evaluate the prevalence of anxiety (A) and depression (D) in patients with K-OLP, analyzing the potential predictors which can affect mental health status. Methods Three hundred K-OLP patients versus 300 healthy controls (HC) were recruited in 15 Italian universities. The Numeric Rating Scale (NRS), Total Pain Rating Index (T-PRI), and Hamilton Rating Scales for Depression and for Anxiety (HAM-D and HAM-A) were administered. Results The K-OLP patients showed statistically higher scores in the NRS, T-PRI, HAM-D, and HAM-A compared with the HC (p-value < 0.001**). A and D were found in 158 (52.7%) and 148 (49.3%) K-OLP patients. Strong linear correlations were identified between HAM-A, HAM-D, NRS, T-PRI, and employment status and between HAM-D, HAM-A, NRS, T-PRI, employment status, and female gender. Multivariate logistic regression revealed that HAM-D and HAM-A showed the greatest increase in the R2 value for A and D in the K-OLP patients, respectively (DR2 = 55.5% p-value < 0.001**; DR2 = 56.5% p-value < 0.001**). Conclusions The prevalence of A and D is higher in the K-OLP patients compared with the HC, also found in K-OLP subjects without pain, suggesting that the processing of pain may be in a certain way independent of the processing of mood. Clinical relevance Mood disorders and pain assessment should be carefully performed in relation to K-OLP to obtain a complete analysis of the patients.

Background Oral lichen planus (OLP) is an immune-mediated inflammatory chronic disease of the oral mucosa, with different patterns of clinical manifestations which range from keratotic manifestations (K-OLP) to predominantly non-keratotic lesions (nK-OLP). The aim of the study was to analyze the differences in the clinical, psychological profile and symptoms between Italian patients of the North and Central-South with K-OLP and nK-OLP. Methods 270 K-OLP and 270 nK-OLP patients were recruited in 15 Italian universities. The Numeric Rating Scale (NRS), Total Pain Rating Index (T-PRI), Hamilton Rating Scales for Depression and for Anxiety (HAM-D and HAM-A), Pittsburgh Sleep Quality Index (PSQI), and Epworth Sleepiness Scale (ESS) were administered. Results The Central-South K-OLP (CS-K-OLP) patients reported a higher frequency of pain/burning compared with the K-OLP patients of the North (N-K-OLP) with higher scores in the NRS and T-PRI (p value < 0.001**). The CS-K-OLP and the CS-nK-OLP patients showed higher scores in the HAM-D, HAM-A, PSQI and ESS compared with the Northern patients (p value < 0.001**). Multivariate logistic regression revealed that the NRS and T-PRI showed the greatest increase in the R2 value for the CS-K-OLP (DR2 = 9.6%; p value < 0.001**; DR2 = 9.7% p value < 0.001**; respectively) and that the oral symptoms (globus, itching and intraoral foreign body sensation) and PSQI showed the greatest increase in the R2 value for the CS-nK-OLP (DR2 = 5.6%; p value < 0.001**; DR2 = 4.5% p value < 0.001** respectively). Conclusions Pain and mood disorders are predominant in patients with OLP in the Central-South of Italy. Clinicians should consider that the geographical living area may explain the differences in oral symptoms and psychological profile in OLP.

Oral lichen planus (OLP) is an immune-mediated inflammatory disease of the oral mucosa characterized by a chronic condition. 1 It may appear with different clinical patterns ranging from keratotic manifestations (K-OLP, white reticular, papular, and/or plaque-like lesions), generally asymptomatic, to predominantly non-keratotic lesions (nK-OLP, atrophic, erythematous, erosive, ulcerative, and/or bullous lesions), 2 which may be symptomatic and impair quality of sleep (QoS), mood, and subsequently the quality of life of the affected patients.The occurrence of two most common sleep disturbances (SDs), insomnia, and daytime sleepiness, with or without mood disorders such as anxiety and depression, has been previously reported in OLP patients (OLPs). 3 However, only a few single center studies have investigated QoS, 4,5 this research based on limited samples, and no data are available in relation to the OLPs with different clinical patterns. Therefore, we aimed to perform a multicenter study in order to further analyze QoS, in a large cohort of OLPs analyzing differences between K-OLP and nK-OLP patterns. Moreover, to the best of our knowledge, this is the first study, which has assessed QoS in such a wide number of OLPs.The objectives of the present study were as follows:• to analyze the prevalence of insomnia and daytime sleepiness and their association with anxiety and depression in patients with keratotic OLP (K-OLPs) and patients with predominant non-keratotic OLP (nK-OLPs), in comparison with a control group of healthy subjects;• to investigate the correlation between poor sleep, anxiety and depression with the oral symptomatology of K-OLP and nK-OLP;• to validate the use of the Pittsburgh Sleep Quality Index (PSQI) in the screening of insomnia in OLPs. | ME THODS | ParticipantsAn observational multicenter case-control study was carried out between December 2018 and January 2020, in accordance with the ethical principles of the World Medical Association Declaration of
