Abstract
OBJECTIVE Carcinoma ex-pleomorphic adenoma (CEXPA) represents a malignant transformation from a recurrent or primary pleomorphic adenoma (PA), and the immune response may be essential in this process. Therefore, in this study, we aimed to identify and quantify subpopulations of dendritic cells (DCs) in CEXPA, residual PA in CEXPA (rPA), and PA. MATERIALS AND METHODS A multicenter study was performed collecting salivary gland tumor (SGT) samples from three Oral and Maxillofacial Pathology Centers. A tissue microarray containing 41 samples of CEXPA and 22 samples of PA was included in this study and submitted to immunohistochemical reactions against CD1a, CD83, CD207, and Ki67 antibodies. RESULTS Both PA and rPA showed a higher quantification of CD207+ and CD83+ cells when compared to CEXPA (p < 0.001 and p < 0.01, respectively). There was also a difference when comparing the cell proliferation index between PA/rPA and CEXPA using the Ki-67 marker (p = 0.043). However, there was no difference in the DC population regarding clinical parameters such as sex, anatomical location, size, and metastases (p > 0.06). CONCLUSIONS Immunohistochemical profile of DC subpopulations and cell proliferation biomarkers in SGTs can contribute as an important tool in the differentiation of benign and malignant tumors or detection of initial areas with malignant transformation.

Abstract
BACKGROUND The differentiation between primary and metastatic salivary gland neoplasms (SGNs) helps in determining appropriate management strategies, including the need for additional diagnostic tests, surveillance, or aggressive treatment. The purpose of this study was to identify and quantify the immature and mature dendritic cells (DCs) in metastatic and no metastatic SGNs and determine its association with clinicopathological findings. MATERIAL AND METHODS Cross-sectional, observational, and descriptive study that includes 33 malignant salivary gland neoplasms [MSGN (6, 18.1% metastatic)], and 22 pleomorphic adenomas (PA), as a control group. Clinical and histopathological characteristics were obtained. Immunohistochemistry for human leukocyte antigen D-related (HLA-DR), CD1a, CD83, and Ki-67 proteins was done. Positive intra- and peritumoral DCs were counted. RESULTS Individuals with MSGN had a lower density of intratumoral HLA-DR+ cells than those with PA (p=0.001), Ki-67 immunostaining was significantly higher in MSGN than in PA (6% vs. 1.4%, p<0.001). Metastatic MSGN showed less intratumoral CD1a+ than non-metastatic (3.2 vs. 165.1, p=0.001). No differences in intra- and peritumoral CD83+ cells were found between benign and malignant SGN. CONCLUSIONS These results suggest that the immune-protective function of intratumoral DCs is compromised in MSGNs. DCs markers may represent useful prediction tools for metastases in salivary gland malignancies, with crucial implications in the implementation of appropriate disease management strategies.

Abstract
Traumatic ulcerative granuloma with stromal eosinophilia (TUGSE) is a rare lesion of a traumatic-reactive nature of the oral mucosa that can clinically mimic an oral carcinoma. A 59-year-old male patient presented painful ulceration with indurated margins on the base of the tongue, extending to the floor of the mouth. The use of ill-fitting denture hurting the mucosa of the region was reported by the patient. The evolution time was 45 days. The presumptive diagnoses were oral squamous cell carcinoma and chronic ulcer. An incisional biopsy revealed an ulceration associated with an eosinophil-rich inflammatory infiltrate and a bed of proliferating histiocyte-like cells in either diffuse or fasciculate arrangement. There was diffuse immunopositivity for CD3, but focal for CD68 and α-SMA, and negativity for CD30. The final diagnosis was TUGSE. The use of the ill-fitting dental prosthesis was suspended and the lesion had complete spontaneous remission three weeks later. TUGSE is an uncommon traumatic self-limiting lesion that must be included in the differential diagnosis of ulcerative lesions resembling oral cancer. The correlation of clinical and histopathological findings is pivotal for a proper diagnosis, avoiding unnecessary aggressive surgical approaches. Key words:Oral ulcer, eosinophilia, immunohistochemical, differential diagnosis.

Abstract
Gelatin-based photopolymerizable methacrylate hydrogel (GelMA) is a promising biomaterial for in situ drug delivery, while aqueous extract of Punica granatum (AEPG) peel fruit rich in gallic acid and ellagic acid is used to improve wound healing. The aim of this study was to develop and analyze the healing properties of GelMA containing AEPG, gallic acid, or ellagic acid in a rodent model. GelMA hydrogels containing 5% AEPG (GelMA-PG), 1.6% gallic acid (GelMA-GA), or 2.1% ellagic acid (GelMA-EA) were produced and their mechanical properties, enzymatic degradation, and thermogravimetric profile determined. Wound closure rates, healing histological grading, and immunohistochemical counts of myofibroblasts were assessed over time. The swelling of hydrogels varied between 50 and 90%, and GelMA exhibited a higher swelling than the other groups. The GPG samples showed higher compression and Young's moduli than GelMA, GGA, and GAE. All samples degraded around 95% in 48 h. GPG and GGA significantly accelerated wound closure, improved collagenization, increased histological grading, and hastened myofibroblast differentiation in comparison to the control, GelMA, and GEA. GelMA containing AEPG (GPG) improved wound healing, and although gallic acid is the major responsible for such biological activity, a potential synergic effect played by other polyphenols present in the extract is evident.

Abstract
BACKGROUND This study aimed to investigate the clinicopathological features of metastases in the oral and maxillofacial regions. METHODS In this retrospective study, biopsy records were obtained from referral centers for oral and maxillofacial diagnosis in Brazil, Guatemala, Mexico, and South Africa. RESULTS A total of 120 cases were evaluated. Of these, 53.78% affected female patients, with a mean age of 57.64 years. Intraosseous lesions were more frequent, particularly in the posterior region of the mandible (49.58%). Clinically, most cases presented with symptomatic swelling, with an average evolution time of 25 months. The clinical diagnostic hypothesis in most instances was that of a malignant lesion. Breast cancer was the most common primary tumor location in females, while lung origin was most common in males. In most cases, the primary cancer was an adenocarcinoma (44.73%). The follow-up period was available for 29 cases, and out of these, 20 had died due to the disease. CONCLUSION Although this is a rare condition, clinicians should be aware that any oral lesions have the possibility of being metastatic, particularly in individuals with a previous history of cancer. The findings from this study could assist clinicians in prompt diagnosing these lesions and subsequent conducting oncologic assessments and treatment.

Abstract
This systematic review aimed to estimate the prevalence and describe dentoalveolar lesions associated with bisphosphonates therapy. A systematic review of the literature was conducted using the following databases: PubMed, Embase, Cochrane, CINAHL, Scopus, Web of Science, Lilacs, SciElo, and Grey Literature. Quality of individual studies analysis was performed by using Newcastle-Ottawa Scale. Certainty of cumulative evidence was achieved by applying Grading of Recommendations Assessment, Development, and Evaluation (GRADE) criteria. The software R Statistics version 4.0.5 (The R Foundation) was used for proportion estimations per study and corresponding confidence intervals were estimated through the Clopper-Pearson method. Four articles were included for the qualitative synthesis. Two studies were considered of good quality, one of fair, and one of poor quality. A total of 231 patients were encompassed. Widening of the periodontal ligament space (22.2-39.7%), periradicular radiolucencies (20-22.9%), and pulp calcifications (33.3-69.2%) were the most frequent alterations. Certainty of evidence was rated as very low. Based on limited evidence, this systematic review reports a variety of dentoalveolar alterations in patients under bisphosphonate therapy. These features might impact on dental clinical practice. However, the level of evidence is considered very low due to important limitations.

Abstract
Considering the side effects in the oral cavity and dental structures of radiotherapy (RDT) for head and neck cancer, this study aimed to evaluate the effects of RDT on the root dentin concerning the obliteration of dentinal tubules, the inorganic composition of intra-radicular dentin, and the integrity of collagen fibers. Thirty human canines were selected from a biobank and randomly divided into two groups (n=15). The samples were sectioned buccolingually, and a hemisection was used for structural analysis by scanning electron microscopy (SEM) and energy-dispersive X-ray spectrometer (EDS). Low-vacuum SEM images were obtained at 2000-x magnification to observe the obliteration of the dentinal tubules. Moreover, compositional evaluation was performed using EDS. After RDT, the SEM and EDS analyses were repeated using the same methodology. RDT was applied fractionally at 2 Gy per day, 5 days per week, for 7 weeks, resulting in a total dose of 70 Gy. The collagen integrity of the irradiated and non-irradiated samples was analyzed using Masson's trichrome and picrosirius red staining polarization microscopy. Samples subjected to RDT exhibited dentinal tubule obliteration (p < 0.001); low integrity of type I and III collagen fibers (p < 0.05); compositional reduction of calcium (p = 0.012), phosphorus (p = 0.001), and magnesium (p < 0.001); an increased Ca/P ratio (p < 0.001). RDT affects the structure of dentinal tubules, the inorganic composition of intra-radicular dentin, and the collagen fiber integrity in the root dentin, which may interfere with the effectiveness and durability of dental procedures.

Abstract
Fibrous dysplasia is a developmental abnormality characterized by the replacement of normal bone tissue by fibrous connective tissue with poorly organized bone trabeculae. This disorder rarely occurs in the craniofacial region, but in such cases it causes facial asymmetries and has severe clinical implications for the patient. This case report describes the treatment of an 18-year-old man who presented with complaints of facial deformity and decreased visual acuity. Cone beam computed tomography revealed a diffuse bone lesion affecting the region of the maxillary, frontal, and nasal bones on the left side of the face. After microscopic examination, the diagnosis of craniofacial fibrous dysplasia was made. The patient underwent a bilateral temporal craniotomy to perform decompression of the orbital apices and correct the loss of visual acuity. In addition, surgical cosmetic contouring of the facial bones was performed. The patient has been followed up by a multidisciplinary team; at his most recent examination, 18 months after the last surgical intervention, his clinical condition remained stable.

Abstract
OBJECTIVE To compare the proportion of young (up to 45 years of age) and older (over 45 years of age) oral squamous cell carcinoma (OSCC) patients who report tobacco and alcohol consumption. METHODS Observational studies reporting tobacco and alcohol consumption among young and older OSCC patients were selected in a two-phase process. Search strategies were conducted on five main electronic databases and complemented by grey literature. The risk of bias was assessed using the Joanna Briggs Institute's Critical Appraisal Checklist for Studies Reporting Prevalence Data. Synthesis of results was calculated with the software R Statistics version 4.0.2 (The R Foundation). RESULTS From 6675 records identified, 38 studies met the eligibility criteria and were selected for qualitative synthesis and meta-analysis, encompassing 2439 young and 13,393 older patients. Tobacco smoking was reported by 39.5% (confidence interval (CI) = 31.7% to 47.9%, I2 = 78%) of the young patients and 48.4% (CI = 37.8% to 59.2%, I2 = 94%) of the older patients. Alcohol consumption was reported by 30.9% (CI = 22.7% to 40.5%, I2 = 83%) of the young and 45.8% (CI = 35.6% to 56.5%, I2 = 95%) of the older patients (P < 0.05). CONCLUSION The comparison in the proportion of individuals reporting tobacco and alcohol consumption demonstrated that these habits were more prevalent in the older group (48.4% and 45.8% respectively) than in the young group (39.5% and 30.9%, respectively). CLINICAL RELEVANCE As a significant proportion of patients with OSCC reported no habits, novel risk factors for OSCC need to be investigated in further research.

Abstract
A solitary fibrous tumor (SFT) is an uncommon mesenchymal tumor characterized by spindle cell proliferation that rarely affects the oral cavity. The clinical and histopathologic features of an oral SFT are described for the benefit of dental practitioners who may encounter one of these rare cases. A 25-year-old man presented with a slow-growing swelling in the left buccal mucosa. A painless, exophytic, and well-circumscribed submucosal lesion was detected, and an excisional biopsy was performed. The biopsy specimen was submitted for histologic and immunohistochemical staining and subsequent microscopic analysis. The histopathologic examination revealed variable cellularity areas that included spindle- and star-shaped cell proliferation. These cells were immersed in a collagenized stroma containing branching vessels with a staghorn arrangement. According to immunohistochemical analysis, the tumor was characterized by STAT6, CD34, β-catenin, and Bcl-2 expression. Diagnosis of oral SFTs is challenging given that their microscopic characteristics can mimic those of malignant mesenchymal neoplasms.

Abstract
Smoking has been shown to alter innate and adaptive immune responses and is directly associated with the onset of oral squamous cell carcinoma (OSCC). The purpose of this study was to evaluate the effect of cigarette smoke exposure on dendritic cells (DCs) from OSCC patients. CD1a and CD83 antibodies were used to identify immature and mature DCs, respectively, by immunohistochemistry in OSCC samples of 24 smokers and 24 non-smokers. Density of DCs was calculated in intra and peritumoral areas. Clinical and microscopic findings were reviewed and analyzed for all patients. Smokers with OSCC had a lower density of intra and peritumoral DCs when compared to non-smokers. Tumors classified as moderately/poorly differentiated had lower peritumoral CD1a+ DCs than well-differentiated tumors (p < 0.001). Smoking contributed to a depletion of immature and mature DCs in the OSCC.

Abstract
BACKGROUND Although new digital pathology tools have improved the positive cell quantification, there is a heterogeneity of the quantification methods in the literature. The aim of this study was to evaluate and propose a novel dendritic cells quantification method in squamous cell carcinoma comparing it with a conventional quantification method. MATERIAL AND METHODS Twenty-six squamous cell carcinomas HIV-positive cases affecting the oropharynx, lips and oral cavity were selected. Immunohistochemistry for CD1a, CD83, and CD207 was performed. The immunohistochemical stains were evaluated by automated examination using a positive pixel count algorithm. A conventional quantification method (unspecific area method; UA) and a novel method (specific area method; SA) were performed obtaining the corresponding density of positive dendritic cells for the intratumoral and peritumoral regions. The Mann-Whitney U test was used to verify the influence of the quantification methods on the positive cell counting according to the evaluated regions. Data were subjected to the ANOVA and Student's t-test to verify the influence of the tumour location, stage, histological grade, and amount of inflammation on the dendritic cells density counting. RESULTS The cell quantification method affected the dendritic cells counting independently of the evaluated region (P-value <0.05). Significant differences between methods were also observed according to the tumour features evaluations. CONCLUSIONS The positive cell quantification method influences the dendritic cells density results. Unlike the conventional method (UA method), the novel SA method avoids non-target areas included in the hotspots improving the reliability and reproducibility of the density cell quantification.

Abstract
Hybrid lesions encompass the occurrence of different entities in one lesion. A 67-year-old woman was referred to the Oral and Maxillofacial Surgery Service for treatment of mandibular Central Giant Cell Lesion (CGCL) previously diagnosed. Intraoral examination revealed edentulism and a painless swelling extending from the alveolar ridge to the buccal vestibule with hard consistency covered by normal mucosae, with unknown duration. Panoramic radiograph revealed a large, multilocular and well-defined radiolucent lesion extending from the region of left mandibular lateral incisor teeth to right mandibular first molar with no evidence of osseous perforation. Initially, a treatment with intralesional injection of corticosteroids was performed. After 18 months of treatment, an increase in size of the osteolytic lesion was noted. An incisional biopsy was carried out and the microscopic examination revealed a unicystic ameloblastoma associated to CGCL. It was performed marsupialization and later the enucleation of residual lesion. The follow-up remains being performed. Key words:Hybrid lesion, central giant cell lesion, ameloblastoma.

Abstract
OBJECTIVES The aim of this study was to investigate the prevalence of oral sarcomas from geographic regions of Brazil. MATERIALS AND METHODS A cross-sectional study was conducted on biopsies obtained from January 2007 to December 2016 at twelve Brazilian oral and maxillofacial pathology centres. Gender, age, evolution time, clinical aspects, tumour location, tumour size at diagnosis, radiographic aspects and histopathological diagnosis were evaluated. Data were analysed using descriptive statistical methods. RESULTS From 176,537, a total of 200 (0.11%) oral sarcomas were reported, and the most prevalent were osteosarcomas (74 cases; 37%) and Kaposi's sarcomas (52 cases; 26%). Males were more affected than females at a mean age of 32.2 years old (range of 3-87 years). The most common symptoms were swelling¸ localised pain and bleeding at a mean evolution time of 5.14 months (range <1-156 months). The lesions were mostly observed in the mandible (90 cases; 45%), with a mean tumour size of 3.4 cm (range of 0.3-15 cm). Radiographically, the lesions presented a radiolucent aspect showing cortical bone destruction and ill-defined limits. CONCLUSIONS Oral sarcomas are rare lesions with more than 50 described subtypes. Osteosarcomas and Kaposi's sarcomas were the main sarcomas of the oral cavity in Brazil.

Abstract
A 47-year-old man was referred for treatment of a painful lesion of 5 months' duration located on the left side of the maxilla. A small perforation in the buccal cortex was observed during the intraoral examination. Cone beam computed tomography (CBCT) showed an extensive, well-delimited radiolucent lesion extending from the alveolar ridge to the nasal cavity. An incisional biopsy was performed, and a cystic lesion consistent with an odontogenic keratocyst (OKC) was observed microscopically. The initial treatment option was decompression to be followed by enucleation. However, 3 months after decompression of the lesion, the patient returned because there was a significant increase in the size of the perforation. A destructive lytic lesion that involved the left side of the maxilla and crossed the midline was evident in the CBCT. The examination of a second incisional biopsy specimen showed epithelial neoplasia comprising islands and projections toward the surface. There was abundant keratin deposition, resulting in the formation of pearls and plugs. A diagnosis of primary intraosseous carcinoma arising from an OKC was confirmed, and the patient underwent a maxillectomy. After 1 year of follow-up, there were no signs of recurrence.

Abstract
BACKGROUND Fatty acid synthase (FASN) is the key molecule for catalyzing fatty acid synthesis and have been associated with several malignant tumors. METHODS We analyzed the expression of FASN and Ki-67, by immunohistochemistry on 29 carcinomas ex-pleomorphic adenoma (CXPAs) and 25 pleomorphic adenomas (PAs). RESULTS Ki-67 proliferation index and FASN expression were significantly higher in patients with CXPA than patients with PA (P < 0.001). We found intense immunoreactivity for FASN in the malignant component of CXPAs, and these malignant areas also had intense nuclear immunoreactivity for Ki-67. CONCLUSIONS The present results suggest that overexpression of FASN in CXPAs might be associated with malignant transformation of ductal epithelial cells and/or myoepithelial cells from PA. FASN associated with Ki-67 may be useful diagnostic markers for CXPA.

Abstract
AIMS Dendritic cells (DCs) are known to play a central role in the regulation of both innate and adaptive immunological responses, including antitumour immunity. The aim of this study was to evaluate the prognostic impact of intratumoral and peritumoral DCs in oral squamous cell carcinoma (OSCC) affecting the tongue and floor of the mouth. METHODS AND RESULTS Immunohistochemistry for CD1a and CD83 was performed in 53 patients with OSCC in the tongue and floor of the mouth. The markers were evaluated by automated examination in intratumoral and peritumoral compartments, and the results were expressed as density of cells/mm2 . Correlations between these data and clinicopathological and survival outcomes were investigated. Depletion of peritumoral CD1a+ cells was associated with lymph node metastasis (P = 0.05), whereas depletion of peritumoral CD83+ cells was correlated with smoking history (P = 0.04), lymph node metastasis (P = 0.015), and extracapsular spread of lymph nodes (P = 0.018). Peritumoral CD1a+ was correlated with recurrence (P = 0.007) and overall survival (P = 0.03). The results of the survival analysis with the Cox proportional hazard model showed that depletion of peritumoral CD1a+ cells is an independent factor associated with overall survival and disease-free survival. CONCLUSION Our results suggest that depletion of peritumoral CD1a+ cells is a strong independent prognostic factor, predicting a higher recurrence rates and worse survival outcomes.

Abstract
AIMS The purpose of this study was to quantify and compare the density of dendritic cells (DCs) in cervical lymph nodes (LNs) and palatine tonsils (PTs) of AIDS and non-AIDS patients. METHODS AND RESULTS Factor XIIIa, CD1a and CD83 antibodies were used to identify migratory DCs by immunohistochemistry in LNs and PTs of 32 AIDS patients and 21 HIV-negative control patients. Quantification was performed by the positive pixel count analytical method. AIDS patients presented a lower density of factor XIIIa(+) cells (P < 0.001), CD1a(+) cells (P < 0.05) and CD83(+) cells (P < 0.001) in cervical LNs and PTs compared to the non-AIDS control group. CONCLUSION Overall depletion of DCs in lymphoid tissues of AIDS patients may be predictive of the immune system's loss of disease control.

Abstract
OBJECTIVE The aim of this study was to quantify the presence of Langerhans cells (LC) in oral lichen planus (OLP) and oral lichenoid lesions (OLL), comparing them with normal epithelium. STUDY DESIGN Thirty-six patients with biopsy-proven OLP or OLL were selected for the study, as well as 23 control subjects free of inflammatory conditions. Immunohistochemical reactions were performed using the streptavidin-biotin peroxidase complex method with CD1a and CD83 primary antibodies. Densities were compared between groups and correlated with microscopic findings. RESULTS Patients with lichenoid conditions (OLP + OLL) presented higher densities of CD1a(+) cells than the control subjects (P = .03). Higher densities of CD1a were associated with a thinner layer of inflammatory cells (P = .02). CONCLUSIONS This study indicates that OLP and OLL are characterized by the recruitment of LC, which may play a significant role on its pathogenesis.
