Objetivos: Identificar y determinar la prevalencia de
cristales de colesterol (CRCo) en granulomas perirradiculares
de origen endodóntico y el tipo de reacción que provocan en
los tejidos circundantes.
Material y métodos: Se estudiaron con microscopía
óptica 75 preparados histológicos de...
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 cytok...
La periodontitis apical es una patología inflamatoria que afecta los tejidos periapicales de un diente desvitalizado. El objetivo de este estudio fue caracterizar histológica y morfométricamente las lesiones de quistes y granulomas utilizando microscopía óptica. Se analizaron seis biopsias obtenidas...
Abstract Objective: This study evaluated the expression of pro-inflammatory (IL-1β, IL-6, IFN-γ and TNF-α) and anti-inflammatory (IL-4 and TGF-β) cytokines in apical periodontitis lesions. Correlations between these cytokines and clinical and cone-beam computed tomographic (CBCT) dat...
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...
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 a...
Abstract Interleukin 17A (IL-17A) is a proinflammatory cytokine responsible for the initiation and propagation of inflammation. One of its actions is the recruitment of neutrophils to the site of infection. The aim of this study was to investigate whether there is association between IL-17A expression an...
As periapicopatias, decorrentes dos insucessos endodônticos, foram estudadas através dos exames clínico, radiográfico e histopatológico de 150 lesöes periapicais. O estudo inter-relaciona os dados obtidos entre si e com os diagnósticos histopatológicos. Parâmetros como dor, tumefaçäo, fístula...
Las células plasmáticas por lo general representan el estado final de diferenciación de los linfocitos B y por lo tanto no sufren una división. Sin embargo, formas binucleadas y ocasionalmente multinucleadas de células plasmáticas se han registrado dentro de los materiales histológicos que contien...
