Desquamative gingivitis (DG) is a clinical term that describes erythema, desquamation and erosions of the gingiva, of various etiologies. Although the clinical aspect is not specific for a certain disease, an accurate diagnosis of the underlying disorder is necessary because the disease course, prognosis and treatment vary according to the cause. DG may inflict significant oral discomfort, which is why patients typically present to the dentist for a first consultation, rendering it important for these specialists to be informed about this condition. Our paper aims to review the ethiopatogenesis and diagnostic approach of DG, focusing on the most common underlying disorders (autoimmune bullous dermatoses and lichen planus) and on the management of these patients. Potential etiological agents leading to an inflammatory immune response in the oral mucosa and DG appearance include genetic predisposition, metabolic, neuropsychiatric, infectious factors, medication, dental materials, graft-versus-host reaction and autoimmunity. A thorough anamnesis, a careful clinical examination, paraclinical explorations including histopathological exam and direct immunofluorescence are necessary to formulate an appropriate diagnosis. Proper and prompt management of these patients lead to a better prognosis and improved quality of life, and must include management in the dental office with sanitizing the oral cavity, instructing the patient for rigorous oral hygiene, periodic follow-up for bacterial plaque detection and removal, as well as topical and systemic therapy depending on the underlying disorder, based on treatment algorithms. A multidisciplinary approach for the diagnosis and follow-up of DG in the context of pemphigus vulgaris, bullous pemphigoid, cicatricial pemhigoid or lichen planus is necessary, including consultations with dermatologists, oral medicine specialists and dentists.

Erosive oral lichen planus (EOLP) represents a significant challenge in dental and medical management due to its chronic inflammatory nature, painful symptoms, and impact on quality of life. This study aims to evaluate the current diagnostic approach with novel non-invasive techniques, such as dermoscopy, and also the landscape of treatment options for EOLP, focusing on its efficacy, safety, and the challenges that it present in clinical practice. Through a comprehensive literature review, we explored the use of topical corticosteroids, systemic immunosuppressants, biologics, and Janus kinase (JAK) inhibitors in treating EOLP, alongside examining patient compliance, psychological impacts, and the risk of adverse effects and recurrence. Our findings reveal that while topical corticosteroids are the cornerstone of EOLP treatment, offering symptomatic relief, their long-term use is limited by side effects and tolerance development. Systemic therapies and biologics provide alternatives for refractory cases but necessitate careful adverse effect monitoring. JAK inhibitors show promise as an innovative treatment avenue but require more evidence on long-term safety and efficacy. This study highlights the necessity of personalized treatment approaches due to the variable disease course and response to treatment, underscoring the importance of a multidisciplinary strategy in managing EOLP. The complexity of EOLP treatment, compounded by its psychological and quality of life impacts, demands ongoing research into targeted therapies, the establishment of standardized treatment protocols, and the development of effective outcome measures to improve patient care and treatment outcomes.

Background/Objectives: Climate change is a major global issue affecting all facets of society, including dentistry. In response, the idea of green dentistry has developed, prioritising the reduction in environmental damage and the protection of patient health. This scoping review seeks to assess the level of awareness, understanding and practices of oral health professionals concerning the proper management of biomed. Methods: Searches were carried out in the Medline/PubMed, Scopus, Web of Science, Embase, and Google Scholar databases, analysing studies published between 2020 and 2025. Out of a total of 822 articles, 27 met the eligibility criteria. Results: In most of these studies, the respondents’ level of knowledge was found to be unsatisfactory or average, and only 17% of the studies reported respondents having a positive attitude towards adherence to sustainability principles. Although many professionals stated they were aware that dental waste could negatively impact the environment and human health if not properly managed, some still failed to provide correct answers to all the questions. Conclusions: The synthesis results indicated that oral health professionals have significant gaps in certain aspects of biomedical waste management, highlighting the need for proper training and to supplement the undergraduate and postgraduate curricula with courses on this topic.

Background and Objectives: Oral cancer remains a critical global health concern, with oral squamous cell carcinoma (OSCC) being the most prevalent form. Oral potentially malignant disorders (OPMDs), such as oral leukoplakia (OLK), oral lichen planus (OLP), and actinic cheilitis (AC), often precede OSCC. Identifying reliable biomarkers is vital for assessing malignant transformation risk. The present study aimed to evaluate the immunohistochemical expression of differentiated embryonic chondrocyte 1 (DEC1), a marker of dysplasia severity, and cluster of differentiation 44 (CD44), which is associated with cancer progression, in OPMD and OSCC tissues. Materials and Methods: A retrospective analysis was conducted on 145 biopsy specimens from January 2015 to January 2023, comprising normal mucosa (NM), OLK, OLP, AC, and OSCC. DEC1 and CD44 expression levels were assessed using immunohistochemical staining. Positivity scores were determined based on staining intensity and extent, with statistical analyses performed using SPSS software (SPSS Inc., Chicago, IL, USA, version 29.0 for Windows). Results: It was found that CD44 expression significantly increased across OPMD and OSCC compared to NM (p < 0.001). Conversely, DEC1 expression was consistent across lesion types and dysplasia levels. CD44 expression was the highest in AC and OSCC, underscoring its potential role as a progression marker. Conclusions: The results indicate that CD44 is a more sensitive marker for assessing dysplastic severity and malignant transformation, while DEC1 may serve as a complementary marker for early-stage evaluation. Further research involving larger cohorts is needed to confirm these findings.

Background/Objectives: Oral potentially malignant disorders (OPMDs), including oral leukoplakia (OLK), oral lichen planus (OLP), and actinic cheilitis (AC), have varying risks of progression to oral squamous cell carcinoma (OSCC). Biomarkers such as aldehyde dehydrogenase 1 (ALDH1) and mammary serine protease inhibitor (Maspin) have shown potential for diagnostic and prognostic use in oral cancer. The present study aimed to evaluate the immunoexpression of aldehyde dehydrogenase 1, a cancer stem cell marker associated with aggressiveness, and the mammary serine protease inhibitor, a potential tumor suppressor, in OPMD and OSCC tissues. Methods: A retrospective analysis was performed on 145 biopsy specimens collected from January 2015 to January 2023, including normal epithelium, OPMDs (OLK, OLP, AC), and OSCC. ALDH1 and Maspin expression levels were evaluated using immunohistochemistry, considering both the percentage of positive cells and staining intensity. Statistical analyses were carried out using the Statistical Package for the Social Sciences (SPSS, version 29.0; IBM Corp., Chicago, IL, USA). Results: Normal oral epithelium showed no expression of ALDH1, whereas 40.6% of OPMDs and 44.4% of OSCC samples exhibited high cytoplasmic ALDH1 expression. Nuclear ALDH1 expression was elevated in 29.7% of OPMDs and 38.9% of OSCCs (p < 0.001). Nuclear Maspin expression was high in 95.2% of normal tissues, in 67.2% of OPMDs and in 55.6% of OSCCs (p < 0.001). Maspin showed strong nuclear and cytoplasmic expression in normal tissue, but its expression decreased in OPMDs and OSCCs, with statistically significant reductions in both compartments (p < 0.001). Conclusions: The results indicate that ALDH1 upregulation and Maspin downregulation are hallmark events in oral carcinogenesis. Their combined evaluation provides a powerful tool for assessing dysplastic severity and malignant transformation risk in OPMDs. Future studies on larger cohorts are needed to confirm the prognostic utility of this dual-marker model.

Background/Objectives: Individuals with autism spectrum disorder (ASD) represent a special population whose characteristics may adversely affect both their own and their families’ quality of life. These characteristics include poor oral health, sensory hypersensitivity, restrictive and repetitive behaviours, communication difficulties, medication-related adverse effects, and associated comorbidities. This scoping review aimed to evaluate the oral health-related quality of life (OHRQoL) of children and adolescents with ASD, as perceived by their parents/caregivers, and to identify the factors associated with these outcomes. Methods: Literature searches were conducted in the MEDLINE/PubMed, Scopus, Web of Science, Embase, and Google Scholar databases. Studies published between 2016 and May 2026 were considered for inclusion. Results: Of the 799 records identified, 23 studies met the eligibility criteria. Among these, 15 used the Parental-Caregiver Perceptions Questionnaire (P-CPQ), an instrument specifically developed for children with cognitive impairments. Most studies reported statistically significant associations between poorer OHRQoL and dental caries experience, lower household income, older age, male sex, and lower parental oral health literacy. Conversely, preventive interventions and comprehensive dental rehabilitation performed under general anaesthesia were associated with improvements in the quality of life of both children and their families. Parents of children with ASD also reported a greater emotional burden, primarily related to responsibility for toothbrushing, dental attendance, the child’s general health status, and the family’s financial situation. Conclusions: The majority of the included studies indicate that, according to parental reports, children and adolescents with ASD experience poor OHRQoL, particularly in the domains of emotional well-being, social well-being, functional limitations, and oral symptoms. These findings highlight the need for targeted preventive strategies and multidisciplinary interventions aimed at improving both oral health and overall quality of life in this vulnerable population.
