1. Fresh Frozen Amniotic Membrane and Buccal Pad of Fat for Reconstruction of Oral Mucosal Defect After Surgical Excision of Leukoplakia
Abstract Objective: To compare the use of Fresh Frozen Amniotic Membrane (FFAM) and Buccal Pad of Fat (BPF) for reconstruction of oral mucosal defect after surgical excision of leukoplakia. Material and Methods: Twenty patients were randomly selected and divided into two groups. Group 1 use amniotic membrane graft and Group 2 BPF. Both groups were evalua

2. Hairy Tongue: Differential Diagnosis by Use of Widefield Optical Fluorescence
Resumo A língua pilosa é uma patologia benigna, caracterizada clinicamente por placas hiperqueratinizadas na face dorsal da língua, semelhante a pelos, cuja coloração varia de despigmentada, esbranquiçada, amarelada, verde, acastanhada a preta. O diagnóstico é clínico, e em casos de placas esbranquiçadas, pode ser difícil diferenciar entre leucopl

3. Expression of E-cadherin and involucrin in leukoplakia and oral cancer: an immunocytochemical and immunohistochemical study
Abstract To assess the immunocytochemical and immunohistochemical correlation of adhesion (E-cadherin) and cell differentiation (involucrin) molecules in oral leukoplakia and oral squamous cell carcinoma. Cytological samples and biopsies were obtained from male and female patients aged over 30 years with oral leukoplakia (n = 30) and oral squamous cell carci

4. Retrospective analysis of the clinical behavior of oral hairy leukoplakia in 215 HIV-seropositive patients
Abstract Oral manifestations are common findings in human immunodeficiency virus (HIV) infected patients and frequently influence the overall health. Oral hairy leukoplakia (OHL) is strongly associated with HIV infection demonstrating its relationship with the individual’s immune status and progression of immunosuppression. This study aims to retrospective

5. Immunoexpression of cleaved caspase-3 shows lower apoptotic area indices in lip carcinomas than in intraoral cancer
ABSTRACT Objective This study aimed to evaluate apoptosis by assessing cleaved caspase-3 immunoexpression in hyperplastic, potentially malignant disorder (PMD), and malignant tumors in intraoral and lower lip sites. Material and Methods A retrospective study using paraffin blocks with tissues from patients with inflammatory fibrous hyperplasia (IFH), act

6. Oral manifestation of tuberculosis: a case-report
Abstract The present case-report describes tuberculosis on the oral mucosa, in a rare manifestation of the disease. The importance of appropriate diagnosis and awareness of the clinical manifestations is highlighted. Oral lesions seem to occur as chronic ulcers, nodular or granular areas, and rare, firm leukoplakia regions. Most extra-pulmonary lesions repre

7. The presence of Helicobacter pylori in oral cavities of patients with leukoplakia and oral lichen planus
ABSTRACT Objective Helicobacter pylori infection is one of the most common bacterial infections in men. This gastrointestinal pathogen is closely related to gastritis, peptic ulcers, and the increased risk of gastric cancer. Numerous studies have indicated oral cavities as possible Helicobacter pylori reservoirs. Helicobacter pylori has been detected both i

8. Altered β-catenin expression in oral mucosal dysplasia: a comparative study
Objective The current study aimed to investigate the β-catenin expression in oral leukoplakia (OL) with different degrees of epithelial dysplasia and normal oral mucosa. Material and Methods Formalin-fixed, paraffin-embedded tissue samples of 39 OL (mild dysplasia n=19, moderate dysplasia n=13, and severe dysplasia n=7), and 10 normal oral mucosa (contr

9. Oral mucosal lesions and their association with sociodemographic, behavioral, and health status factors
The aim of this study was to evaluate the frequency of oral mucosal lesions and their associations with sociodemographic, health, and behavioral factors in a southern Brazilian population. Information was collected from participants (n = 801) using a structured questionnaire during an oral cancer screening campaign held at an agribusiness show in southern Br

10. Oral potentially malignant disorders in a large dental population
Objectives Oral cancer (OC) may be preceded by clinically evident oral potentially malignant disorders (OPMDs). Oral carcinogenesis is a multistep process that begins as epithelial hyperplasia and progresses to oral epithelial dysplasia and finally to fully malignant phenotypes. The aim of our study was to estimate the prevalence of OPMDs in a large popula

11. Oral cancer from a health promotion perspective: experience of a diagnosis network in Ceará
The aim of this study is to share the experience of implementing a network for the diagnosis of oral cancer by integrating primary, secondary, and tertiary oral health care centers and identifying the possible weaknesses of the process. The study also investigated the risks of exposure to the main risk factors for oral and lip cancer and their most common po

12. Atividade gelatinolítica in situ e imuno-expressão das metaloproteinases 2 e 9 em lesões potencialmente malignas e carcinomas espinocelulares bucais / In situ gelatinolytic activity and immunoexpression of metalloproteinases 2 and 9 in oral potentially malignant lesions and squamous cell carcinomas
The transition from normal oral mucosa to invasive carcinoma has a complex and multifactorial etiology. Oral leukoplakia (OL) is regarded as the most prevalent potentially malignant oral lesion, with a higher tendency for malignant transformation if compared to normal oral mucosa. Although an increased activity of matrix metalloproteinases (MMPs) 2 and 9 in
