1. The mechanism: how dental resorptions occur in ameloblastoma
RESUMO As reabsorções radiculares “em plano” ou “em corte” são características do ameloblastoma e foram consideradas patognomônicas dessa lesão, diferenciando-o do cisto ósseo simples, queratocisto odontogênico e do cisto nasopalatino - nos quais elas estão ausentes, nos dentes envolvidos. Apesar dessa frequência elevadíssima e importante

2. Macrophages subpopulations in chronic periapical lesions according to clinical and morphological aspects
Abstract: The aim of this study was to evaluate macrophage M1 and M2 subpopulations in radicular cysts (RCs) and periapical granulomas (PGs) and relate them to clinical and morphological aspects. M1 macrophages were evaluated by the percentage of CD68 immunostaining associated with the inflammatory cytokine TNF-α, and M2 macrophages, by its specific CD163 a

3. Analysis of CD57+ natural killer cells and CD8+ T lymphocytes in periapical granulomas and radicular cysts
Abstract: The aim of this study was to compare the number of CD57+ natural killer (NK) cells and CD8+ T lymphocytes between periapical granulomas (PGs) and radicular cysts (RCs). Twenty-fives cases of PGs and 25 of RCs were submitted to histological analysis and immunohistochemistry using anti-CD57 and anti-CD8 biomarkers. Positive cells were counted in 10 f

4. Treg and Th17 cells in inflammatory periapical disease: a systematic review
Abstract: The process involved in periapical lesions, which occur as an outcome of pulpal necrosis, is regulated by the immune system including regulatory T cells (Treg) and T helper 17 cell (Th17) responses. The objective of this study was to conduct a frequency systematic review to determine the presence of Treg/Th17 responses and the influence of these ce

5. Immunohistochemical expression of TGF-β1 and MMP-9 in periapical lesions
Abstract The objective of this study was to evaluate the expression of matrix metalloproteinase 9 (MMP-9) and transforming growth factor beta (TGF-β1) in periapical lesion samples correlated with the intensity of the inflammatory infiltrate and thickness of the epithelial lining. Forty-five cases of periapical lesions (23 periapical granulomas and 22 radicu

6. Analysis of 153 cases of odontogenic cysts in a South Indian sample population: a retrospective study over a decade
The purpose of this study was to determine the prevalence of odontogenic cysts and to identify their clinico-pathological features among patients by studying biopsy specimens obtained from the archives of the Department of Oral and Maxillofacial Pathology, College of Dental Sciences, Davangere, Karnataka, India, during the past 10 years. Data for the study w

7. Immunohistochemical expression of p63, epidermal growth factor receptor (EGFR) and notch-1 in radicular cysts, dentigerous cysts and keratocystic odontogenic tumors
O objetivo deste estudo foi avaliar a expressão imunoistoquímica da proteína p63, receptor do fator de crescimento epidérmico (EGFR) e Notch-1 no revestimento epitelial de cistos radiculares (CR), cistos dentígeros (CD) e tumores odontogênicos queratocísticos (TOQ). Para este estudo, 35 CR, 22 CD e 17 TOQ foram utilizados. Os dados clínicos e epidemi

8. Histopathological study of radicular cysts diagnosed in a Brazilian population
O propósito desse estudo foi investigar os aspectos histopatológicos de cistos radiculares diagnosticados em uma população brasileira. Setenta e três casos de cistos radiculares entre 1480 biópsias diagnosticadas na Faculdade de Odontologia da Universidade Federal da Bahia, entre 2001 e 2008, foram investigados, considerando os seus aspectos histopatol

9. Immunohistochemical expression of vascular endothelial growth factor and matrix metalloproteinase-9 in radicular and residual radicular cysts
OBJECTIVE: This study assessed and compared the immunoexpression of vascular endothelial growth factor (VEGF) and matrix metalloproteinase-9 (MMP-9) in radicular cysts (RCs) and residual radicular cysts (RRCs), relating them to the angiogenic index and the intensity of the inflammatory infiltrate. MATERIAL AND METHODS: Twenty RCs and 10 RRCs were evaluated b

10. Perfil imunoistoquímico de citoqueratinas em cistos radiculares / Immunohistochemical profile of cytokeratins in radicular cysts
O objetivo deste estudo foi determinar o perfil de citoqueratinas (CKs) em cistos radiculares por meio da expressão imunoistoquímica das citoqueratinas 34BE12, 5, 8, 10, 14, 16 e 19 e correlacioná-la com a intensidade do infiltrado inflamatório presente na cápsula conjuntiva e a espessura do revestimento epitelial. Para o estudo, foram analisados 56 cas

11. Avaliação histopatológica e expressão imunoistoquímica de PTHrP e receptor de PTH/PTHrP tipo I em cistos radiculares, cistos dentígeros e tumores odontogênicos queratocísticos / Histopathological evaluation and immunohistochemical expression of PTHrP and receptor of PTH / PTHrP type I in radicular cysts, dentigerous cysts and odontogenic tumors keratocystic
O objetivo deste estudo foi analisar as características histopatológicas e expressão imunoistoquímica comparativa de PTHrP e seu receptor PTH/PTHrP tipo I no revestimento epitelial e na cápsula fibrosa de cistos radiculares, cistos dentígeros e tumores odontogênicos queratocísticos. Para tanto, foram analisados 35 casos de cisto radicular, 22 de cist
