The condition of the oral mucosa in somatic pathology

Lesions of the oral mucosa (SOPR) are often the primary pronounced clinical symptom of somatic diseases. It is possible to find out which pathogenetic mechanisms and links of somatic pathology create conditions for the implementation of risk factors, the implementation and development of structural and functional disorders in the oral mucosa, with the aim of targeted therapeutic effects on changes in the SOPR and the general condition of the body as a whole. The purpose of the study was to establish the structure of diseases of the oral mucosa depending on gender and age in patients with various somatic pathology. Materials and methods: A survey was conducted of 164 patients who sought advice from the Dental Hospital of Khabarovsk. Between the ages of 18 and 89. The average age of patients was (55.7 ± 1.38) years. All the subjects were divided into 4 groups depending on their age and the presence of diseases of internal organs. The comparison group included 30 somatically preserved patients of similar age and gender, by random sampling. Results: It was found that with pathology of the oral mucosa, women out of the total number of cases were 2.5 times more than men. The greatest number of patients’ complaints about the diseases of COPD was in the age group of 60-74 years, unlike other age groups: 18-44 years by 1.8 times; 45–59 years by 1.2 times; 75–89 years by 2.7 times, respectively. Most diseases of the oral mucosa are manifested in the presence of systemic pathology. Somatic diseases were detected in 62.2 % of patients with COPD. Pathology of internal organs and systems affects 70.42 % of patients with lichen planus, 50 % of patients with leukoplakia, 80 % of patients with candidiasis, 26.32 % of patients with chronic aphthous stomatitis and 79.17 % of patients with glossitis. Diseases of the gastrointestinal tract are 1.2 and 2.8 times more dominant in the structure of the lesions of the SOPR compared to the pathology of the cardiovascular and endocrine system. Findings: The revealed pattern of manifestations of pathological changes in the oral mucosa against the background of somatic pathology is of great diagnostic importance not only for dentists of various profiles, but also for clinicians of specialized departments, since ultimately all this affects the timeliness and quality of medical and diagnostic care for this category of patients.

Lack of oral involvement in a large cohort of women with vulvar lichen sclerosus - a multicenter prospective study.

We assessed the prevalence of oral lichen sclerosus in a cohort of women affected with vulvar lichen sclerosus (VLS). This prospective, observational study included adult female patients with a histologically proven VLS who attended the Vulva Clinics of three Dermatology Units from January 2020 to July 2023. During this period, all VLS patients were asked to be examined in their oral cavities in order to detect any possible sign of oral diseases, which were then biopsied. Three hundred women (mean age 64.5 ±13.0years) were included, of whom 21 (7%) had a concurrent extragenital LS. In six (2%) patients, white, non-removable lesions were found at oral inspection and biopsied. All cases were histologically lichen planus. No other clinically relevant oral lesions were found. The six women with histologically proven oral lichen planus had more frequent periodontal and autoimmune diseases than the other included subjects. Our findings confirm the absolute rarity of oral involvement in patients with VLS. They suggest that the oral mucosa, unlike the genitals, is a setting which weakly leads to development of LS, also in predisposed subjects.

Immunohistochemical Expression of Immune Regulatory Proteins in Interface Dermatoses.

Cutaneous immune-related adverse events (irAEs) of immunotherapies, such as anti-programmed cell death protein-1 (PD-1), suggest that immune checkpoint factors may contribute to the pathobiology of lichenoid interface dermatitis in immunotherapy-naïve patients. Our study aimed to describe innate and adaptive immune markers via immunohistochemical (IHC) staining of lichenoid interface dermatoses. We studied the staining patterns of PD-L1, STING, IL-36 gamma, CD8, PD-1, and LAG-3 in five interface dermatoses: oral lichen planus (LP) (n = 10), cutaneous LP (n = 10), chronic cutaneous lupus erythematosus (CLE) (n = 11), erythema multiforme (EM) (n = 11), and toxic epidermal necrolysis (TEN) (n = 13), by immunohistochemistry (IHC) analysis. Expression was evaluated semi-quantitively according to the percentage of keratinocytes and dermal lymphocytes stained compared to keratinocytes and resident pericapillary lymphocytes in normal human skin. All interface dermatoses evaluated showed increased expression of PD-L1 on keratinocytes and LAG-3 in lymphocytes. STING was increased on the keratinocytes of most specimens. Expression of IL-36 gamma, in basal layer keratinocytes was more extensive in oral LP and cutaneous LP and varied in CLE, EM, and TEN. Lymphocytic infiltration expressing PD-1 was elevated in oral LP, cutaneous LP, and CLE. Current thinking is that interface dermatitis is the result of a cell-mediated immune reaction involving cytotoxic CD8+ T-cell-mediated apoptosis of keratinocytes. The findings of this study suggest that in addition to cell-mediated immunity, innate immune factors may contribute to pathobiology.

Sexual Distress and Quality of Life in Women With Genital Erosive Lichen Planus-A Cross-sectional Study.

The study aimed to assess sexual distress and quality of life in women with moderate-to-severe genital erosive lichen planus (GELP). Thirty-six women with GELP were recruited at the Oslo University Hospital in Norway. The diagnosis was confirmed by a dermatologist with experience in vulvovaginal disease and based on characteristic clinical changes in the vulva and/or vagina, and biopsy results if available. Clinical severity was measured using the GELP score with a score ≥5 required for inclusion. Sexual distress was measured using the revised Female Sexual Distress Scale (FSDS-R), and quality of life was measured using the Dermatology Life Quality Index (DLQI). Topical steroid treatment was allowed. The mean FSDS-R score was 22.7 (range 0-45) with 27 women reporting high scores for sexual distress (FSDS-R score >15). The mean DLQI score was 8.8 (range 1-19) with 15 women reporting a moderate impact (DLQI score 6-10), and 12 women reporting a very large impact (DLQI score 11-20) of GELP on their quality of life. No clear correlations were found between disease severity assessed by GELP scores and FSDS-R or DLQI scores. Age was not correlated with FSDS-R or DLQI scores. These results demonstrate that a substantial number of women with GELP experience sexual distress and a reduced quality of life.

Facial dyschromias: A review of clinical and dermoscopic features

Facial dyschromias are a common complaint among individuals with skin of color. Until the advent of dermoscopy, clinical examination and histopathology were used to arrive at a definitive diagnosis. Dermoscopy is an emerging tool used to diagnose various pigmentary conditions. It may be used to diagnose various facial dyschromias, including melasma, lichen planus pigmentosus, facial acanthosis nigricans, post-inflammatory pigmentation, maturational dyschromia, vitiligo, and salt and pepper pigmentation, to name a few. Some of these conditions show characteristic dermoscopic features, thereby obviating the need for a skin biopsy for confirmation of diagnosis. Dermoscopy is, therefore, a reliable, non-invasive tool which can be used to diagnose various facial dyschromias.

Utilizing laser therapy to manage oral potentially malignant disorders in older adults at the primary care level.

Oral lesions are a significant concern among older adults because they can progress to oral cancer if not diagnosed and treated promptly and effectively. Transportation to the hospital is a major barrier to oral healthcare for many older adults. The purpose of this editorial is to address the challenges of managing oral potentially malignant disorders in the older population, highlighting the barriers they face in accessing healthcare services, the potential use of laser therapy for management, and the direction of research in this area. Due to the limited access of the older to healthcare services, primary healthcare facilities within communities serve as their primary providers. Laser therapy is recommended for the management of oral potentially malignant disorders due to its favorable outcomes. This approach has been tested in several primary healthcare centers in Thailand. In our project, laser therapy was used to treat oral potentially malignant disorders in primary and secondary healthcare services. This includes photodynamic therapy for older patients with extensive lesions, as well as individuals with oral leukoplakia and erythroplakia who have declined curative surgery. It has also been used in cases of recalcitrant lichen planus to steroid or photobiomodulation therapy. This approach has been well accepted by both oral healthcare providers and patients. To expand access to these treatment options in such settings, it is critical to empower healthcare professionals, particularly dentists and dental nurses, to integrate laser techniques into geriatric care and oral cancer screening. Establishing a network foundation for orofacial laserology would also enhance the potential of such settings.

Clinical Improvement and P63-Deficiency Correction in OLP Patients After Photobiomodulation

Background: Oral lichen planus (OLP) is a chronic inflammatory disease associated with the formation of symptomatic lesions in the mouth. P63 is essential for epidermal development and regeneration. Weak expression of this protein has been shown in OLP lesions. Photobiomodulation (PBM) therapy has been reported to reduce OLP symptoms, but its ability to correct the molecular perturbations of the disease has not been studied. This study aimed to evaluate the efficacy of PBM in OLP treatment by evaluating changes in p63 expression and their association with clinical response. Methods: Twenty OLP patients underwent PBM with a diode laser (810 nm), (0.50 W, 30 s, 1.2 J/cm2), 3 times weekly for a month. The treatment efficacy index (EI) was calculated based on pain-level values and clinical scores of lesions before and after therapy. Biopsies were taken before and after therapy, analyzed immunohistochemically for p63 expression, and compared with 10 healthy controls. Results: P63 levels in OLP lesions were significantly lower than those in normal oral mucosa. After treatment, the pain level and clinical scores of the lesions decreased significantly. The calculated EI showed PBM effectiveness in 90% of cases. Increased p63 positivity and staining intensity were observed after therapy. Conclusions: The established p63 deficiency in OLP lesions is likely an important molecular mechanism in the pathogenesis of the disease. Laser irradiation at 810 nm increased p63 expression to a level close to that found in the healthy epithelium and significantly improved the symptoms and clinical signs of OLP. All of this determines the effectiveness of PBM therapy in the management of OLP.

Perturbed saliva microbiome is gender-specific in patients with oral lichen planus

ObjectiveTo understand the gender characteristics of oral lichen planus (OLP) by identifying the gender-specific salivary microbiome and its potential biomarkers. MethodsA gender-based study was undertaken, commencing with the collection of saliva samples, followed by 16S rRNA gene sequencing, to explore the differences in the composition of saliva microbiome in OLP patients (40 males and 56 females) and healthy controls (40 males and 56 females), respectively. ResultsBoth male and female OLP patients had significant differences in saliva microbiome composition from healthy controls, especially in female patients. Notably, Pseudomonas was only enriched in female patients. Rhodococcus (AUC: 0.91) and Pseudomonas (AUC: 0.97) had great potential as diagnostic biomarkers in male and female patients, respectively. The KEGG results showed metabolic dysfunction was more pronounced in female patients and a high level of microbial metabolism in diverse environments, ABC transporters, Quorum sensing and Two-component system. Capnocytophaga was negatively correlated with the erosion area in male patients. Neisseria was negatively correlated with the erosion area and Rothia was positively correlated with the pain level in female patients. ConclusionsOur study revealed gender-specific perturbation in salivary microbiome within OLP patients, suggesting that the male and female patients with OLP may have different pathogenesis.

Efficacy of Combined vs. Monotherapy in Oral Lichen Planus: A Randomized Clinical Trial.

The aim of this study was to compare the topical therapeutic efficacy of triamcinolone acetonide (TA) (0.2%) plus hyaluronic acid (HA) (0.1%) versus monotherapy in patients with symptomatic oral lichen planus (OLP), as well as to investigate the oxidative stress of saliva under the different treatments. Sixty OLP patients were included in a randomized, double-blind, singlecenter study with a treatment duration of 28 days and 3-month follow-up period. Participants were randomized into three groups: Group I (TA + HA), Group II (TA), and Group III (HA). Treatment efficacy was assessed by means of Thongprasom scale, Oral Health Impact Profile-14 (OHIP-14), and visual analog scale (VAS). In addition, biochemical analyses were performed in order to determine the level of antioxidant biomarkers in saliva, including superoxide dismutase (SOD), glutathione (GSH), and total antioxidant capacity (TAC). All treatments seem to exhibit a significant effect in accordance with Thongprasom scale (p < 0.001), VAS reduction (p < 0.001), and OHIP14 (p < 0.05), which maintains over time. No significant changes in salivary oxidative stress in any of the three groups occurred. The results exhibited a significant improvement in the treated patients in all three groups. There were no significant changes in salivary stress biomarkers under treatment condition.

Genetic and therapeutic for oral lichen planus and diabetes mellitus: a comprehensive study

BackgroundThis study employed a bidirectional Mendelian Randomization (MR) approach to explore the causal relationships between Oral Lichen Planus (OLP), diabetes mellitus (DM), and glycemic control. It also aims to identify potential pharmacological and herbal treatments that effectively address both OLP and the metabolic dysfunctions associated with DM.MethodsThis study employs a two-way MR approach to investigate the potential causal relationships between diabetes type and glycated hemoglobin (HbA1c) levels, and the risk of OLP. We analyzed differentially expressed genes from the OLP dataset in the Genomics Expression Omnibus (GEO) database, cross-referencing these with HbA1c-related genes for enrichment analysis. Additionally, the Drug-Gene Interaction Database (DGIdb) and Traditional Chinese Medicine Systems Pharmacology Database (TCMSP) were utilized to assess the effectiveness of specific drugs, herbs, and ingredients in treating OLP while managing blood glucose levels.ResultsThe MR analysis revealed a significant association between Type 1 Diabetes mellitus (T1DM) and an increased risk of OLP, unlike Type 2 Diabetes mellitus (T2DM). This finding indicates a unique immunological interaction in T1DM that may predispose individuals to OLP. The drug prediction analysis focused on core targets linked to OLP and HbA1c, evaluating the therapeutic potential of retinoic acid, prednisone, and thalidomide for treating OLP and regulating blood glucose levels. Additionally, herbal medicines such as Ecliptae herbaand Amygdalus communis vas, along with herbal ingredients like quercetin, luteolin, and 17-beta-estradiol, were identified for their anti-inflammatory properties and potential to mitigate metabolic dysfunction in diabetes.ConclusionThe study highlighted a complex interplay between diabetes and OLP, underscoring the efficacy of integrated therapeutic strategies that target both conditions. The findings suggest that both pharmaceutical and herbal treatments can effectively manage the clinical manifestations of OLP and associated metabolic challenges. This holistic approach to treatment could significantly enhance patient outcomes by addressing the interconnected aspects of these chronic conditions.

Expression of neutrophil extracellular trap-related proteins and its correlation with IL-17 and TNF-α in patients with oral lichen planus.

Neutrophil extracellular traps (NETs) are produced by polymorphonuclear neutrophils (PMNs) stimulated by interleukin-17 (IL-17) and tumor necrosis factor α (TNF-α). However, the level and role of NETs in oral lichen planus (OLP) remain poorly understood. This study aimed to investigate the expression of NETs in OLP and explore the correlation between NETs and the levels of IL-17 and TNF-α. The expression and distribution of NET-related proteins in tissue samples from each group were assessed using hematoxylin-eosin (HE) staining and immunofluorescence (IF). Additionally, the expression of NET-related proteins in peripheral blood samples from each group was evaluated using cell IF technique and fluorescence spectrophotometry. The relative formation level of NETs in each group was determined by fluorescence spectrophotometry via plasma co-culture. Furthermore, the levels of inflammatory cytokines IL-17 and TNF-α in plasma and culture supernatant were measured using enzyme-linked immunosorbent assay (ELISA). NET-related proteins were located in the subepithelial and lamina propria layers of OLP lesions. OLP had significantly higher expression of NET-related proteins in lesion tissues and peripheral blood compared to the healthy control (HC) group (p < 0.05). The rate of NETs formation in the erosive-stage OLP (EOLP) group was significantly higher than that in the HC group (p < 0.05), in contrast, no significant increase was observed in the non-erosive OLP (NEOLP) group (p > 0.05). Furthermore, the levels of IL-17 and TNF-α in the EOLP group were significantly elevated compared to those in the NEOLP group and HC group (p < 0.05), while the levels in the NEOLP group did not significantly differ from those in the HC group (p > 0.05). The rate of NETs formation showed a positive correlation with the levels of IL-17 and TNF-α in plasma. The expression of NET-related proteins was upregulated in OLP lesion tissues and peripheral blood. Elevated levels of IL-17 and TNF-α in peripheral blood plasma positively correlated with the rate of NETs formation, suggesting that IL-17 and TNF-α mediate the formation of NETs in OLP patients, and may thereby contribute to the development of OLP.

Psychiatric Symptoms in Patients with Immune-Related Mucocutaneous Lichen Planus

Background: Lichen planus (LP) is one of the most common chronic mucocutaneous diseases with an underlying immunological component. Although the pathogenesis of this condition is not exactly known, numerous studies have been conducted due to the significance of this disease and its high prevalence. Several risk factors and various contexts have been identified for this condition; however, the primary cause is still not fully understood. Some genetic and environmental factors may be involved in the development of the disease. The present study was conducted to examine psychiatric symptoms in patients with cutaneous-oral LP (COLP) referred to the dermatology clinic of Sina Hospital of Tabriz city, northwest of Iran. Methods: This descriptive study was conducted on 31 patients with LP and 31 healthy individuals referred to the dermatology clinic of Sina Hospital in Tabriz. The information required was collected using the SCL-90-R standard questionnaire, and the data were analyzed using descriptive and inferential statistics with the help of SPSS v.23 and multivariate analysis of variance (MANOVA). Results: The results showed that people with COLP do not suffer from serious psychiatric conditions but may have merely mild to moderate psychiatric symptoms. However, the MANOVA test indicated that the symptoms had a significantly higher incidence in patients with oral LP compared to matched control subjects (F (12,47)=13.86, P&lt;0.05). Conclusion: As shown by the SCL-90-R standard checklist, patients with oral LP expressed significantly more psychiatric symptoms than normal individuals, reflecting the need for these patients for more regular assessments.

Histopathological study of scaly plaque over palm and sole in patients attending a tertiary care Hospital in Kathmandu

Background: Dermatoses of palms and soles are frequently encountered as palms and soles have non-hairy skin. Scaling skin could be a symptom of many medical conditions including psoriasis, eczema, contact dermatitis, ichthyosis, actinic keratosis, lichen planus, tinea, etc. Psoriasis must be differentiated from its non-psoriatic lesions. Histopathological examination often serves as a confirmative part of the diagnosis. Materials and methods: This was a hospital-based retrospective study carried out in the Department of Pathology and Department of Dermatology of Nepal Medical College Teaching Hospital. A total of 139 cases of scaly plaque skin lesions of the palm and sole from January 2020 to December 2022 were included in the study. The histopathological diagnosis was correlated with the clinical diagnosis. Results: Among 139 persons presenting with scaly lesions, the median age was 36 years with an age range from 15 years to 80 years. A female preponderance (59%) was observed. The odds of Psoriasis were 2.5 times higher (OR CI: 1.21 to 5.17) among those aged 36 years and above (P value 0.011). There was a significant association between age categories and histological diagnosis of scaly lesions. The agreement was significant between the clinical and histological diagnosis for psoriatic (63.0%) and non-psoriatic lesions (76.3%) with a Cohen’s kappa coefficient of 0.38 (SE: 0.084), P value &lt; 0.0001. Conclusions: Both psoriatic and non-psoriatic lesions can present as scaly plaque skin lesions, hence the knowledge of these clinical mimickers is important for the proper diagnosis. The histopathological examination will give the confirmatory diagnosis.

Impact of Topical Fluocinonide on Oral Lichen Planus Evolution: Randomized Controlled Clinical Trial.

To examine the impact of fluocinonide 0.05% gel formulation for the topical treatment of oral lichen planus (OLP). Through an RCT design, 47 patients with OLP were randomly allocated for topical OLP treatment with fluocinonide 0.05% (n = 23) or placebo (n = 24). Patients were examined for OLP symptoms, signs, disease severity, and extension score changes over 6-month follow-up. After 6 months, in comparison with placebo, patients treated with fluocinonide experienced a significant reduction of OLP symptoms (p = 0.024), signs (p = 0.014), and OLP extension score (p = 0.028). The two-way ANOVA estimation models revealed that treatment with fluocinonide determined, at 6 months, a positive significant effect on the reduced OLP signs (p = 0.017), OLP symptoms (p = 0.026), and OLP extension score (p = 0.028). The multivariate regression analysis highlighted that anxiety, stress, and depression were significant predictors of every analyzed OLP outcome (p < 0.05 for each parameter) and that patients who had baseline anxiety, depression, and stress gained more benefits from fluocinonide at 6-month follow-up. Topical fluocinonide 0.05% was more efficacious compared to placebo in reducing OLP outcomes at 6-month follow-up. Anxiety, depression, and stress were significant predictors of OLP outcomes and positively impacted the treatment with fluocinonide at 6 months.

Immunohistochemical examination of immunoreactivity of transient receptor potential melastatin 2, glutathione peroxidase 4 and spexin in lichen planus.

In this study, we aimed to investigate the potential contributions to the disease by examining the immunoreactivities of SPX in LP-affected skin tissue using immunohistochemical methods, in light of its recent prominence as a molecule related to diabetes mellitus, along with apoptosis and ferroptosis mediated by GPX4 and TRPM2 channels facilitating oxidative stress-induced cell death. This research explored the immunohistochemical expressions of TRPM2, GPX4, and SPX in Lichen Planus (LP) patients compared to healthy individuals. Forty skin samples were collected, split equally between LP patients and healthy controls, excluding those with other conditions. Samples underwent immunohistochemical staining for TRPM2, SPX, and GPX4, using secondary antibodies and chromogens AEC or DAB. Histoscores were calculated based on staining diffusiveness and severity. Statistical analyses were performed with SPSS 22.0, using t-tests and ANOVA, with significance set at p < 0.05. There were no demographic differences between groups (p > 0.05). LP patients showed significantly lower TRPM2 and GPX4 histoscores and higher SPX histoscores compared to controls (TRPM2 and GPX4: p < 0.001, SPX: p < 0.001). Gender and age did not affect histoscores significantly. Findings suggest TRPM2, GPX4, and SPX play roles in LP pathogenesis, indicating a need for further molecular studies to clarify their involvement. This contributes to understanding LP beyond the traditional apoptosis perspective.

A Comparison of Traditional Chinese Medicine and Multiple Conventional Therapy in Treating Oral Lichen Planus: A Network Meta-analysis.

To evaluate and compare the efficacy of seven conventional treatments and traditional Chinese medicine (TCM) combined therapies for oral lichen planus. This study employs PubMed, Web of Science, Cochrane Library, and Cnki to collect studies. After evaluating the quality and bias risk, RevMan 5.4.1 and R Gemtc package was utilised with a visual analogue scale and side effects as outcomes, to compare the efficacy of the seven treatments. This study included 20 studies, with a sample size of 1669. Our results suggest that photodynamic therapy and TCM demonstrate the most significant decrease in visual analogue scale and the rank is as follows: photodynamic therapy > TCM > TCM combined with non-hormonal immunosuppressive drugs > TCM combined with glucocorticoids > chloroquine combined with glucocorticoids > non-hormonal immunosuppressive drugs > glucocorticoids. Among them, compared to glucocorticoids, photodynamic therapy (-1.55, 95% CI: (-3.09, -0.02)), TCM (-1.25, 95% CI: (-2.46, -0.06)) significantly outperform in statistics. Moreover, no side effects were reported by the photodynamic therapy treatment. In the comparison with non-hormonal immunosuppressive drugs, the result indicates TCM (-4.17, 95% CI (-8.24, -0.34)), glucocorticoids (-2.78, 95% CI (-5.69, -0.17)) and their combination (-2.83, 95% CI (-5.93, -0.05)) have a significantly lower probability of the appearance of side effects. This study indicates that TCM, from the perspectives of efficacy and the likelihood of side effects, outperforms all other common therapies, besides photodynamic therapy, in treating oral lichen planus.

Demographic and Clinical Characteristics of Pre-Malignant Oral Lesions and their Related Factors in an Iranian Population: A Registry-Based Study

Background: Oral Potentially Malignant Disorders (OPMDs) can lead to Oral Squamous Cell Carcinoma (OSCC). The sixth most common cancer in the world is OSCC. This study aimed to describe the demographical and clinical characteristics of OPMD patients and their risk factors registered at the Oral Medicine Department of Shahid Beheshti Dental School in 2019-2021. Methods: The observational-analytical study was conducted using the dental records of 96 consecutive patients using a web-based registration software (OPMDs registry). Information including demographics and clinical features, the type of OPMD, and risk factors were extracted. Data were analyzed using the Chi-square test, T-test, and Fisher’s exact test with SPSS version 21. Results: In this study, 96 patients (average age: 52.41±14.87) including 52 women and 44 men, participated. The most common OPMDs comprised 69 Oral Lichen Planus (OLP) and 15 leukoplakia. The most common location of lesions was the buccal mucosa (74%) with erosions and plaques being the most common morphology types. Most patients with leukoplakia were male, however, majority of the patients with OLP were female (p=0.001). In patients with leukoplakia, 66.5% were smokers; hence, a significant relationship between smoking and OPMD was observed (p=0.001). Patients with OLP commonly presented with burning symptoms, while patients with leukoplakia were mostly asymptomatic (p=0.004). Conclusion: A significant relationship was observed between gender, clinical symptoms, location of lesions, morphology, and type of OPMDs. Most patients with OPMDs were women with OLP in their buccal mucosa, suffering from burning sensation.
