Abstract
PURPOSE The extracellular polysaccharide (EPS) is produced by the bacterium Zoogloea sp. and plays a positive role in tissue repair. The purpose of this study was to clinically and histologically compare the effects of EPS in the healing of traumatic oral ulcers in rats with the effects of triamcinolone. METHODS Ulcers were induced in the oral mucous of 45 male Wistar rats, divided into three groups: control group, treated with triamcinolone, and treated with biopolymer gel. In the clinical evaluation, we considered the weight variation of the animals and the size of the lesion area, at baseline and on treatment days 1, 3 and 7. The histological parameters evaluated were the type and intensity of the inflammatory infiltration, the presence of necrosis and foreign body granuloma and the degree of re-epithelialization of the lesion. RESULTS The reduction of the lesion area was greater in the animals treated with EPS, with no difference in the intensity of the inflammatory infiltration between the groups on days 3 and 7 of treatment. CONCLUSIONS The results suggest that topical application of EPS in traumatic oral ulcers of rats promotes faster repair than triamcinolone ointment, without increasing the intensity of inflammatory infiltration under the lesion.

Abstract
BACKGROUND Temporomandibular disorders (TMD) do not only occur in adults but also in adolescents, with negative impacts on their development. AIM To propose a predictive model for TMD in adolescents using a decision tree (DT) analysis and to identify groups at high and low risk of developing TMD in the city of Recife, PE, Brazil. DESIGN This cross-sectional study was conducted in Recife on 1342 schoolchildren of both sexes aged 10-17 years. The analyses were performed using Pearson's chi-squared test and Fisher's exact test, as well as the CHAID algorithm for the construction of the DT. The SPSS statistical program was used. RESULTS The prevalence of TMD was 33.2%. Statistically significant associations were observed between TMD and sex, depression, self-reported orofacial pain, and orofacial pain on clinical examination. The DT consisted of self-reported orofacial pain, orofacial pain on physical examination, and depression, with an overall predictive power of 73.0%. CONCLUSION The proposed tree has a good predictive capacity and permits to identify groups at high risk of developing TMD among adolescents, such as those with self-reported orofacial pain or orofacial pain on examination associated with depression.

Abstract
OBJECTIVES This multicenter study aimed to evaluate cases of non-syndrome and syndromic odontogenic keratocyst, as well as cases of recurrence within these two groups. METHODS This descriptive, analytical, retrospective cross-sectional study evaluated the sex, age and presence of multiple lesions in 1,169 individuals seen at 10 Brazilian oral and maxillofacial pathology centers. Of these, 1,341 odontogenic keratocysts were analyzed regarding clinical diagnosis, size, site, imaging appearance, signs and symptoms, type of biopsy, treatment, and recurrence. RESULTS There was a similar distribution by sex. The median age of non-syndromic and syndromic patients was 32 and 17.5 years, respectively. The posterior mandible was the site most affected by small and large lesions in both groups and in recurrent cases. Unilocular lesions were more frequent, also in recurrent cases. Mainly small lesions showed this imaging appearance. Signs and symptoms were absent in most cases. Conservative treatment was the most frequent modality in all age groups, regardless of the patient's condition and recurrence. Recurrences were uncommon. CONCLUSION This study showed a higher frequency of non-syndromic keratocysts in the population. Clinicopathological features related to the involvement of multiple sites, age, and recurrence may differ between syndromic and non-syndromic cases. Furthermore, we found an association between lesion size and some clinical features and between the time interval to recurrence and the syndromic spectrum. CLINICAL RELEVANCE To contribute to a better understanding of the distribution and association between clinical, imaging, and sociodemographic characteristics in each spectrum of the lesion.

Abstract
The aim of the present study was to analyze the epidemiology of maxillofacial odontogenic and non-odontogenic cysts diagnosed for 30 years in a Brazilian population. A retrospective descriptive cross-sectional study was performed. Biopsy records were obtained from the archives of a Brazilian referral center between 1989 and 2019. Data regarding age, gender, anatomical location, and histopathological diagnosis were collected and categorized. Further, a literature search for similar studies was performed. A total of 6.994 biopsy records were evaluated, but only 367 (5.24%) cases were classified as odontogenic cysts (OC) or non-odontogenic cysts (NOC). Among all cystic lesions, 341 cases (92.9%) were OC and 26 cases (7.1%) were NOC. These lesions were more common in females (n = 208 / 56.67%) and located mostly in the mandible (n = 195 / 53.1%). In patients with OC, the radicular cyst was the most frequent (n = 134 / 36.5%), followed by the dentigerous cyst (n = 101 / 27.5%) and the odontogenic keratocyst (n = 52 / 14.2%). Patients with NOC had a higher frequency of epidermoid cyst (n = 12 / 3.3%), oral lymphoepithelial cyst (n = 7 / 1.9%), and nasopalatine duct cyst (n = 4 / 1.1%). The OCs were more prevalent than NOCs, and inflammatory cysts were the most common among all the OCs.

Abstract
BACKGROUND/AIM Due to the increase in incarceration rates, the prison community has attracted much concern in the recent past. Although people in prison are often socially disadvantaged and vulnerable to a range of health problems, there is a lack of information on the oral health conditions of prisoners. Thus, the aim of this study was to survey the oral problems of a sample of the male incarcerated population of Brazil, focusing on dental trauma. MATERIAL AND METHODS The research was undertaken over a three-month period in 2017. It was a cross-sectional study of 756 prisoners of the Curado Prison Complex, located in Recife, PE. Using a previously calibrated examiner, dental trauma was measured with the Andreasen index. Etiology of dental trauma and socio-demographic data were collected with questions developed for this survey. Standard descriptive statistics were used to report frequency estimates. The chi-square test, Fisher's exact test, and Mann-Whitney U-test were used to compare groups. In addition, a binary logistic regression was performed to identify whether the studied variables could predict the occurrence of dental trauma. RESULTS The prevalence of dental trauma in the sample was 10.8% and most of the cases (42.7%) occurred due to violent events. A higher frequency of violent etiology was observed in cases that occurred during imprisonment (p = 0.037). Individuals that suffered dental trauma during incarceration were more likely to have been incarcerated for longer periods of time (p = 0.043). The main type of injury found was enamel and dentin fracture without pulp exposure (68%). The most affected tooth was the upper right central incisor (40%). CONCLUSION These results underline the high prevalence of dental trauma experienced by men in prison.

Abstract
We evaluated the antifungal and antibiofilm potential of the hydroalcoholic extract of bark from Anadenanthera colubrina (vell.) Brenan, known as Angico, against Candida spp. Antifungal activity was evaluated using the microdilution technique through the Minimum Inhibitory and Fungicide Concentrations (MIC and MFC). The antibiofilm potential was tested in mature biofilms formed by Candida species and analyzed through the counting of CFU/mL and scanning electron micrograph (SEM). In vivo toxicity and therapeutic action was evaluated in the Galleria mellonella model. The treatment with the extract, in low doses, was able to reduce the growth of planktonic cells of Candida species. MIC values range between 19.5 and 39 µg/mL and MFC values range between 79 and 625 µg/mL. In addition was able to reduce the number of CFU/mL in biofilms and to cause structural alteration and cellular destruction, observed via SEM. A. colubrina showed low toxicity in the in vivo assay, having not affected the viability of the larvae at doses below 100mg/kg and high potential in the treatment of C. albicans infection. Considering its high antifungal potential, its low toxicity and potential to treatment of infections in in vivo model, A. colubrina extract is a strong candidate for development of a new agent for the treatment of oral candidiasis.

Abstract
PURPOSE The aim of this study was to describe the relation between occlusal features and enzyme replacement therapy in patients with mucopolysaccharidoses. MATERIALS AND METHODS A cross-sectional study was conducted. The sample consisted of 20 patients with mucopolysaccharidoses, 10 of whom were undergoing treatment at a hospital in northeast Brazil. Occlusal features were evaluated by clinical examination and panoramic radiography. A structured questionnaire was administered to evaluate the dental care of each patient. Pearson χ2, Fisher exact, and Mann-Whitney tests were used for data analysis, with a level of significance of 5%. RESULTS Marked overjet (75%) and anterior open bite (70%) were the most frequent occlusal alterations, and 15% had Class III disorders. Radiography visualized the presence of impacted teeth (75%) and prolonged retention of deciduous teeth (65%). Patients with enzyme replacement therapy had a lower average maximum protrusion (P = .033). A total of 75% of mothers said they had not been advised to take their children to the dentist and 10% of children had never been to the dentist. CONCLUSION Patients with mucopolysaccharidoses exhibited notable occlusal alterations, especially marked overjet and anterior open bite. Enzyme replacement therapy seems to influence the maximum protrusion of patients.

Abstract
The aim of this study was to determine the number of FoxP3+ regulatory T (Treg) cells in the microenvironment of lower lip squamous cell carcinomas (LLSCCs) and to correlate the findings with clinicopathological parameters (tumor size/extent, regional lymph node metastasis, clinical stage, and histopathological grade of malignancy). Fifty cases of LLSCC were selected. Lymphocytes exhibiting nuclear immunostaining for FoxP3 were quantified in 10 microscopic fields at the deep invasive front of LLSCCs. The results were analyzed statistically using the nonparametric Mann-Whitney test and Fisher's exact test. FoxP3+ lymphocytes were observed in all cases studied. The number of these cells tended to be higher in smaller tumors, tumors without regional lymph node metastasis, and tumors in early clinical stages, but the difference was not statistically significant (p > 0.05). Low-grade tumors contained a larger number of FoxP3+ lymphocytes than high-grade tumors (p = 0.019). Tumors with an intense inflammatory infiltrate exhibited a larger number of Treg cells (p = 0.035). On the other hand, the number of FoxP3+ lymphocytes was smaller in tumors arranged in small cell clusters (p = 0.003). No significant differences in the number of FoxP3+ lymphocytes were observed according to the degree of keratinization (p = 0.525) or nuclear pleomorphism (p = 0.343). The results suggest the participation of Treg cells in immune and inflammatory responses in the microenvironment of LLSCCs. These cells may play a more important role in early stages rather than in advanced stages of lip carcinogenesis.

Abstract
Background The studies found in the literature associate the immunoexpression of hMLH1
and hMSH2 proteins with histologic aspects, but do not correlate it with
clinical and epidemiological data. Objective To evaluate the immunoexpression of hMLH1 and hMSH2 in actinic cheilitis,
correlating it with clinical characteristics. Methods We analyzed 40 cases. Histological and immunohistochemical analyses were
performed. The following clinical variables were evaluated: gender, age
range, ethnicity, clinical aspect and occupational sunlight exposure.
Statistical evaluation included the Student t-test, while the significance
level was set at 5%. Results Greater immunoexpression of hMLH1 and hMSH2 was observed in females,
individuals aged over 40, and mixed-race/black patients. Furthermore, the
immunoexpression of these proteins was greater in actinic cheilitis with a
white-colored appearance and in patients without occupational sunlight
exposure. No statistical differences were observed for the variables
studied. Conclusion This study uncovered variations of hMLH1 and hMSH2 protein expression upon
evaluation of clinical aspects in actinic cheilitis.

Abstract
This research aimed to compare the efficacy of digital panoramic radiography (DPR) with that of cone beam computed tomography (CBCT) for delineation of odontogenic and nonodontogenic tumors. From November 2009 through March 2011, 23 tumors in the maxillomandibular complex were diagnosed by histopathological examination. All DPRs and CBCTs were obtained and analyzed by a single previously calibrated radiologist, who considered the following radiographic aspects: clarity of the lesion edges, relation with dental elements, involvement of adjacent anatomical structures, cortical bone expansion and disruption, and, if present, type of involved anatomical structures and site of bone expansion and disruption. Of 23 patients, 15 (65.2%) were male and 8 (34.8%) were female. The tumor was classified as odontogenic in 73.9% of patients and nonodontogenic in 26.1% of patients. Analysis revealed that 56.5% of the tumors were located in the mandible, 34.8% in the maxilla, and 8.7% in both arches. For all analyzed variables, CBCTs offered more accurate details than did DPRs. Panoramic radiography should not be the examination of choice to visualize lesions in the maxillomandibular complex.

Abstract
BACKGROUND Patients with diabetes mellitus have been associated with a number of changes in the oral cavity, such as gingivitis, periodontitis, mucosal diseases, salivary dysfunction, altered taste, and burning mouth. OBJECTIVES To determine the prevalence of oral mucosal lesions in patients with diabetes mellitus. METHODS A cross-sectional observational study between August and October 2012 with a convenience sampling was performed for 51 patients with diabetes mellitus (type 1 and type 2). The study consisted of two phases: 1) a questionnaire application; 2) intraoral clinical examination. For the analysis of data, we used descriptive statistics, Fisher's exact test in bivariate analysis (significance level of 0.05), and Poisson Regression. RESULTS The prevalence of oral lesions was 78.4%. Traumatic ulcers (16.4%) and actinic cheilitis (12.7%) were the most prevalent lesions. The lips (35.3%) and tongue (23.5%) were the most common location. The bivariate analysis showed an association with the type of diabetes, and two variables (age and comorbidity) were quite close to the significance level. In the Poisson Regression analysis, only diabetes type 2 remained significant after adjusting the model. CONCLUSIONS The results of this study show a high prevalence of oral mucosal lesions in diabetic patients. The oral mucosal lesions are mostly associated with diabetes type 2.

Abstract
An increasing incidence of oral squamous cell carcinoma (OSCC) in individuals younger than 45 years has been observed in recent years. OSCC in younger patients differs in terms of biological behavior and prognosis with the disease being more aggressive than in older patients. The aim of this study was to analyze the immunohistochemical expression of galectins-3 and -7 in 32 cases of OSCC in young patients and to correlate this expression with clinical and morphological parameters. All cases of OSCC of the sample were diagnosed at oncology referral hospitals in Paraíba, Brazil, between 2002 and 2012. Clinical data were obtained from the patient records. Histological malignancy grading systems proposed by Bryne et al. (J Pathol 166:375-381, 1992) and the World Health Organization (In: Pathology and genetics of head and neck tumours: Word Health Organization classification of tumours, 2005) were used for morphological analysis. Immunohistochemistry was performed by the streptavidin-biotin technique using anti-galectin-3 and -7 antibodies. The results were analyzed statistically by the Chi-squared and Fisher exact tests (p < 0.05). Immunoexpression of galectin-3 was observed in 65.6 % of the cases analyzed, but showed no significant association with any of the variables studied (clinical staging; histological malignancy grading systems). Immunoexpression of galectin-7 was observed in 96.9 % of cases and was significantly associated with histological malignancy grading systems (p < 0.05). In conclusion, the results suggest the use of galectin-7 as marker of biological behavior and tumor progression in OSCC in young patients.

Abstract
Osteoblastoma is a benign neoplasia and is uncommon in the jaws. In some cases, this lesion presents extremely aggressive local characteristics and is termed aggressive osteoblastoma. Because the clinical, radiographic and histopathologic characteristics are similar to those of a variety of benign and malignant tumors, it poses a diagnostic dilemma. This report presents a case of an aggressive osteoblastoma in the mandible and discusses the differential diagnosis of this lesion. A 13-year-old white male sought the Stomatology Clinic at the State University of Paraíba, Campina Grande, PB, Brazil, complaining of asymptomatic swelling on the left side of his face. Cone-beam computerized tomography showed a multilocular, hypodense bone lesion, located in the body of the left mandible and lower third of the ascending ramus. The initial diagnostic hypothesis was juvenile ossifying fibroma or osteosarcoma. After histopathologic examination, the final diagnosis was aggressive osteoblastoma. Surgical resection with a safety margin was performed. There was no evidence of recurrence after a follow-up period of 4 years.

Abstract
INTRODUÇÃO: As lesões bucais e peribucais são comuns nos pacientes infectados pelo vírus HIV e podem representar os primeiros sinais da doença, antes mesmo das manifestações sistêmicas. OBJETIVO: Este estudo objetivou estimar a prevalência de manifestações bucais em indivíduos soropositivos para o HIV, considerando aspectos sociodemográficos, imunológicos e terapêuticos. MATERIAL E MÉTODO: Foi realizado um estudo de natureza clínico-epidemiológica transversal, entre outubro de 2007 e abril de 2008, com amostra composta por 40 pacientes. Utilizou-se a técnica de observação direta intensiva por meio de exame clínico apropriado. Os dados foram registrados em fichas pré-elaboradas e analisados por estatística descritiva e inferencial. RESULTADO: Verificou-se a prevalência do gênero feminino (52,5%), na faixa etária de 40 a 49 anos (45%). O tratamento com antirretrovirais foi constatado em 85,0% dos casos, sendo todos com terapia de alta potência (HAART). Observou-se que 52,5% dos pacientes apresentaram a contagem de linfócitos TCD4+ acima de 500cél/mm³ e 50,0% apresentaram carga viral indetectável. A prevalência das manifestações bucais foi 42,5%, sendo a mais expressiva a candidose pseudomembranosa (19,23%), seguida da periodontite úlcero-necrosante (15,38%), da leucoplasia pilosa (11,54%) e da queilite angular (11,54%). Não foi verificada associação entre manifestações bucais e carga viral (p=0,1268), nem com o número de células T CD4 (p=0,3458). CONCLUSÃO: A prevalência de algumas manifestações bucais associadas à infecção pelo HIV ainda é alta, sendo a candidose pseudomembranosa a infecção mais prevalente, principalmente entre pessoas com baixo nível de escolaridade e maior tempo de infecção pelo vírus HIV, independentemente da terapia utilizada e do estado imunológico do paciente.

Abstract
BACKGROUND Actinic cheilitis (AC) is a potentially malignant disorder of the lip caused by exposure to solar radiation. OBJECTIVES This study was conducted to evaluate the clinicopathologic profile of cases of AC and to verify associations with the degree of dysplasia. METHODS This retrospective study analyzed data for 40 patients with AC. Demographic, clinical, and histopathologic data were evaluated. Sections measuring 5 μm in thickness were cut, deparaffinized, and stained with hematoxylin and eosin for histologic examination. The degree of epithelial dysplasia was graded using the criteria defined by the World Health Organization. Two calibrated oral pathologists analyzed the slides. RESULTS Analysis of the AC patients sampled showed that 75.0% were male (P=0.002), 80.0% were aged≥40 years (P<0.001), 74.3% were Caucasian (P=0.004), and 68.6% had occupational exposure to sunlight (P=0.028). The most common clinical manifestation was white lesions (55.0%), and 40.0% of patients had no dysplasia. No significant associations emerged between the histologic grading of AC and gender (P=1.000), age (P=1.000), ethnicity (P=0.416), occupational exposure to sunlight (P=1.000), and clinical presentation (P=0.467). CONCLUSIONS The degree of dysplasia in AC was not statistically associated with gender, age, ethnicity, occupational exposure to sunlight, or clinical appearance. This study provides some support for the hypothesis that clinicopathologic features are not related to the degree of dysplasia in AC.

Abstract
Introduction Adenoid cystic carcinoma (ACC) is one of the most frequent malignant salivary gland tumors, which commonly affects the minor salivary glands of the mouth and is rare in the nose and paranasal sinuses. In the maxillary sinus, ACC can mimic inflammatory diseases and has a poor prognosis. Objective To report a case of a 50-year-old man with ACC of the maxillary sinus whose clinical findings in the alveolar ridge mimicked an oroantral fistula. Case Report An excisional biopsy was performed and histopathologic analysis revealed ACC. Lung metastases and residual tumor in the maxillary sinus were detected by imaging methods. In view of the poor general health of the patient, no new surgical intervention was performed and he was only treated by radiotherapy and follow-up. Conclusion Although rare in the maxillary sinus, ACC should be included in the differential diagnosis of lesions affecting this site.

Abstract
Myofibroblasts are hybrid-phenotype differentiated cells in between fibroblasts and smooth muscle cells. Due to their contractile features and ability to synthesize extracellular matrix components, cytokines, proteases, and proangiogenic factors, myofibroblasts have been implicated in the pathogenesis of fibrocontractive diseases and in the progression of many tumors, including oral squamous cell carcinoma (SCC). Objective To perform a literature review on the origin of myofibroblasts, their main morpho-physiological and immunohistochemical aspects, and to discuss the correlations with oral SCC. Method A search was made on the PUBMED database to select the main papers in the literature in English related to the subject, published between January 1991 and December 2011. Conclusion Myofibroblasts are an important component of the stroma of oral SCCs, although they are not present in all tumors. Abundant presence of myofibroblasts may be associated with local disease recurrence and decreased patient survival. However, given the relatively limited number of studies on the subject, further research is needed to clarify the molecular mechanisms by which myofibroblasts influence the biological behavior of oral SCC.

Abstract
AIM This study investigated the immunohistochemical expression of hMLH1 and hMSH2 proteins in lower lip squamous cell carcinoma (SCC) and actinic cheilitis (AC), to contribute to the understanding of the development of lower lip cancer. METHODS AND RESULTS Forty cases of lower lip AC and SCC were studied. Quantitative immunohistochemical analysis was undertaken by counting 1000 cells (positive and negative) in each lesion. Statistical evaluation included Student's t-test and one-way ANOVA. For SCC and AC, the mean number of hMLH1- and hMSH2-positive cells decreased with advanced stage of the lesion. The largest mean number of immunostained cells was observed in AC cases without dysplasia or with mild dysplasia (hMLH1: 721.23 ± 88.116; hMHS2: 781.50 ± 156.93). Intermediate values were obtained for AC with moderate or severe dysplasia (hMLH1: 532.86 ± 197.72; hMHS2: 611.14 ± 172.48). Lower lip SSCs presented the smallest number of positive cells (hMLH1: 255.03 ± 199.47; hMHS2: 518.38 ± 265.68). A statistically significant difference was observed between groups (P < 0.001). CONCLUSIONS The results support the hypothesis that changes in the immunoexpression of these mismatch proteins are related to the process of carcinogenesis of the lower lip.

Abstract
Epithelial-myoepithelial carcinoma was first described by Danath et al. in 1972 and is classified as a rare low-grade biphasic neoplasm of the salivary glands. This case report presents a male patient who had a lesion in the oral mucosa with a history of recurrence of the tumor. The outcome resulted in a profile consistent with an epithelial-myoepithelial carcinoma with a high degree of transformation. The case highlights the importance of histopathological evaluation of oral lesions, which occasionally may not present typical clinical aspects of malignant lesion.

Abstract
Mucopolysaccharidosis (MPS) is a group of rare metabolic diseases characterized by intralysosomal accumulation of glycosaminoglycans. MPS type VI or Maroteaux-Lamy syndrome is an autosomal-recessive syndrome caused by mutations in the lysosomal enzyme arylsulfatase B. A defect in the gene leads to accumulation of nondegraded mucopolysaccharides, resulting in severe cellular dysfunction with multisystem expression. The oral manifestations of MPS VI are not well described in the literature. This paper presents a series of seven patients with MPS VI, with the description of the general clinical manifestations and focus on the still rarely studied oral manifestations of the syndrome. Among them were high palate, open bite, impacted and/or included teeth, thickening of the pericoronal follicle, and changes in the temporomandibular joint.

Abstract
It was assessed the immunohistochemical profile of CD25+ cells in cases of chronic gingivitis (CG) and chronic periodontitis (CP). Immunohistochemistry was carried out using streptoavidin-biotin complex and anti-CD25 antibody in 17 cases of CG and 25 cases of CP. Sixteen cases (94.1%) of CG were immunopositive. CD25 was focally expressed in 50% of the sample and diffusely expressed in 25%. The stained cells were localized not only beneath the epithelium, but also far from it. In relation to the cellular density quantification of CD25+ cells, score ++ was the most common. Concerning CP, all cases were immunopositive. CD25+ cells were expressed in focal or diffuse pattern either close or far from the epithelium. Diffuse distribution of positive cells throughout the connective tissue was seen in 60% of the cases and 32% showed focal or diffuse cellular pattern. Sixteen cases (64%) received score +++. It was identified that CD25+ cells are present in either a focal or a diffuse pattern in connective tissue. Significant differences in the density of cellular immunostaining between CG and CP were found. The greatest density was observed in CP cases, which suggests that the infiltrate of lymphocytes show a higher degree of cellular activation in periodontitis compared with gingivitis.

Abstract
O presente trabalho objetivou estudar a influência do processo inflamatório na expressão dos filamentos intermediários de citoqueratinas utilizando espécimes de gengivite crônica, além de traçar um perfil destes polipeptídeos na gengiva inflamada. Para tanto, foi feita uma avaliação histomorfológica, no que diz respeito ao tipo e intensidade do infiltrado inflamatório presente na gengivite crônica e a análise imuno-histoquímica da expressão das citoqueratinas 10, 13, 14 e 16, quanto à localização topográfica no epitélio em 10 casos de gengivite crônica. Constatou-se que o tipo de infiltrado inflamatório presente na gengivite crônica foi intenso e predominantemente mononuclear. Quanto aos achados imuno-histoquímicos, observou-se uma redução e até mesmo a ausência de expressão da CK 10 em cerca de 70% da amostra, a expressão da CK 13 estendendo-se por toda a camada suprabasal na grande maioria dos casos (90%), bem como expressão da CK 14 em toda a extensão do epitélio (90%) e ainda expressão variável da CK 16. A partir destes achados, concluiu-se que a expressão das citoqueratinas é alterada durante a inflamação, e que o processo inflamatório interfere na maturação epitelial, cujas evidências foram encontradas nas mudanças no perfil destas proteínas na gengiva inflamada.

Abstract
In order to contribute to the knowledge of the pathogenesis of periodontal disease, an immunohistochemical analysis of the density of inflammatory mononucleated cells and the number of dendritic cells was performed using anti-CD4, anti-CD20, anti-CD25, anti-CD68 and anti-protein S-100 antibodies in 17 cases of chronic gingivitis (CG) and 25 of chronic periodontitis (CP). The CD4+ and CD68+ cells exhibited a diffuse distribution in the connective tissue. CD20+ cell distribution was predominantly in groups and the CD25+ cells exhibited a diffuse or focal distribution. The S-100+ cells were identified in the epithelium and the lamina propria, exhibiting distinct morphology and number. The statistical analysis showed no significant differences (p>0.05) between CG and CP regarding the density of the CD4+ and CD20+ cells and the number of S-100+ cells. However, significant differences (p<0.05) were found between the groups in the density of CD25+ and CD68+ cells . The density of macrophages was greater in CG and the level of cellular activation of the lymphocyte infiltrate was greater in CP. No differences were detected between the aforementioned conditions regarding the density of the T and B lymphocytes and to the number of the dendritic cells.

Abstract
The aim of the present study was to clinically, morphologically, and immunohistochemically correlate the expression of cytokeratins (CKs) 7, 10, 13, 14, 16, and 19 in 30 cases of tongue squamous cell carcinoma (SCC) with disease outcome, metastases, clinical stage (tumor, node, metastasis [TNM]), and histological grade of malignancy proposed by Bryne. Statistical analysis (chi2 test) showed that only histological grading was not significantly correlated with the clinical variables. CK expression varied in the samples analyzed. CK 10 expression was significantly correlated with the presence of metastases, and the expression of CK 16 was related to disease outcome and also to TNM stages III and IV. These results indicate that metastases and TNM are effective prognostic indicators. The histological grading proposed by Bryne did not reflect the biological behavior of the tongue SCC cases studied. Analysis of some intermediate CK filaments can reflect the biological behavior and aggressiveness of some tongue SCCs.

Abstract
OBJECTIVE Cytokeratins (CKs) are the intermediate filament proteins of the epithelium cells, which have become important markers of normal and abnormal cell differentiation. The goal of the present study was to investigate the expression pattern of CK 10, 13, 14 and 16 in oral verrucous carcinoma (OVC) and oral squamous papilloma (OSP). MATERIAL AND METHODS Formalin-fixed paraffin-embedded sections from eight cases of each lesion were assessed. Immunohistochemistry was carried out using streptoavidin-biotin complex method. RESULTS In OVC, CK 10 was expressed in suprabasal to superficial layers whereas in OSP mainly in superficial layer. CK 13 was detected in prickle and superficial cells in most cases of OVC and in suprabasal to superficial cells of OSP. All the cell layers of OVC reacted positively for CK 14 while basal and suprabasal layers of OSP were more pronounced for CK 14. Finally, CK 16 was observed in suprabasal to superficial layer in OVC and the majority cases in OSP showed only superficial reactive cells. CONCLUSIONS CK 10, 13, 14 and 16 immunohistochemical profile emphasis the biological behavior of the studied lesions and confirm the use of these proteins as markers of differentiation.

Abstract
OBJECTIVE Investigate the immunohistochemical distribution of fibronectin, tenascin, laminin and collagen IV in syndrome (SOKC) and non-syndrome odontogenic keratocysts (NSOKC). MATERIALS AND METHODS Ten cases of SOKC and five of NSOKC were selected and streptoavidin-biotin technique was applied. The specimens were analyzed taking into account the following evaluation parameters: presence, continuity and thickness in the basement membrane and intensity, distribution and association with inflammatory cells in the cyst wall. RESULTS Differences could be detected regarding tenascin, fibronectin and collagen IV between the SOKC and NSOKC. Tenascin was present in all cases along the basement membrane in SOKC and in five cases of NSOKC predominated negative areas. Furthermore, tenascin distribution was focal in the cyst wall in SOKC whereas in NSOKC it was diffuse. Concerning fibronectin, it was detected as a discontinuous band when present in SOCK and as a continuous band in NSOKC. Collagen IV was not present in the majority of the cases in SOKC. Negative areas for laminin predominated in the basement membrane in both groups. CONCLUSIONS These findings show differences between the immunohistochemical expression of tenascin, fibronectin and collagen IV which might indicate a more aggressive biological behavior of SOKC as compared with NSOKC.
