Variability in the Epithelial Expression of Ki67 and Polarization Characteristics of Collagen in Odontogenic Cysts and Tumours

ABSTRACT Objective: To assess the proliferation of epithelium (using the Ki67 index) and the polarization pattern of collagen in selected odontogenic cysts and tumours. In addition, an exploratory analysis of the effect of inflammation on the proliferation rate was done. Material and Methods: Following...

¿Los Quistes Periradiculares Dependen de la Infección Endodóntica?

Los quistes periradiculares, tanto los de bolsillo como los verdaderos, son de origen inflamatorio; sin embargo, en la literatura ha existido una gran controversia asociada, en primer lugar, a la dependencia de la infección contenida dentro del sistema de conductos radiculares y, en segundo lugar, al ti...

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 cytok...

Periodontitis apical: caracterización histológica y morfométrica de quistes radiculares y granulomas periapicales

Int. j. morphol; 36 (4), 2018
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...

Pro-inflammatory and anti-inflammatory cytokine expression in post-treatment apical periodontitis

J. appl. oral sci; 26 (), 2018
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...

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...

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 a...

Lesöes periapicais crônicas: inter-relacionamento histopatológico, radiográfico e clínico dos insucessos endodônticos

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...

Estudo histolatológico e radiográfico de lesöes apicais
Histopathological and radiographical study of apical lesions

CCS; 7 (1), 1985
Apresenta-se o estudo histopatológico e análise radiográfico de lesöes apensas aos ápices, quando da exodontia do elemento dentário. Por meio do exame microscópico, foram diagnosticados granulomas e cistos periapicais. Os granulomas apresentaram modificaçöes nos seus caracteres histopatológicos...
