Cytotoxicity and inflammatory mediators release by macrophages exposed to real seal xt and sealapex xpress

Braz. dent. j; 32 (1), 2021
Abstract This study evaluated the cytotoxicity of Sealapex Xpress and Real Seal XT and their effect on macrophage activation. J774.1 macrophages were incubated with Sealapex Xpress and Seal Real XT (0.1, 1.0, and 10 mg/mL) for 24 and 48 h. Cell viability was assessed by the MTT assay and macrophage activ...

Bond strength of experimental root canal sealers based on mta and butyl ethylene glycol disalicylate

Braz. dent. j; 29 (2), 2018
Abstract This study investigated the bond strength of two experimental root canal sealers based on MTA and butyl ethylene glycol disalicylate: MTAe and MTAe-HA. The reference materials used for comparison were AH Plus and MTA Fillapex. Twenty human upper incisors were selected and one 1 mm slice was obta...

Antiedematogenic activity of the indole derivative N-salicyloyltryptamine in animal models

An. acad. bras. ciênc; 90 (1), 2018
ABSTRACT The N-salicyloyltryptamine (NST) is an indole derivative compound analogue to the alkaloid N-benzoyltryptamine. In the present study, the antiedematogenic activity of NST was investigated in animal models. Firstly, the acute toxicity for NST was assessed according to the OECD Guideline no. 423. ...

Specific immediate early gene expression induced by high doses of salicylate in the cochlear nucleus and inferior colliculus of the rat

Abstract Introduction: Salicylate at high doses induces tinnitus in humans and experimental animals. However, the mechanisms and loci of action of salicylate in inducing tinnitus are still not well known. The expression of Immediate Early Genes (IEG) is traditionally associated with long-term neuronal m...

Efficacy and safety of superficial chemical peeling in treatment of active acne vulgaris

An. bras. dermatol; 92 (2), 2017
Abstract: Acne vulgaris is an extremely common condition affecting the pilosebaceous unit of the skin and characterized by presence of comedones, papules, pustules, nodules, cysts, which might result in permanent scars. Acne vulgaris commonly involve adolescents and young age groups. Active acne vulgaris...

1, 3, 4-Thiadiazole and 1, 2, 4-triazole-3(4 H )-thione bearing salicylate moiety: synthesis and evaluation as anti- Candida albicans

Abstract Dramatically increased occurrence of both superficial and invasive fungal infections has been observed. Candida albicans appear to be the main etiological agent of invasive fungal infections. The anti-C. albicans activity of thiosemicarbazide, 1,3,4-Thiadiazole, and 1,2,4-triazole-3(4H)-thione c...

Variabilidad de la respuesta plaquetaria a la aspirina

Introducción y objetivos: A pesar de que el estudio Antiplatelet Trialists' Collaboration demostró una reducción del 25% de los eventos mayores con el uso de aspirina en enfermos de alto riesgo, un porcentaje de pacientes presentan eventos isquémicos recurrentes. Esto ha llevado a la descripción de ...

Antimicrobial action of calcium hydroxide-based endodontic sealers after setting, against E. faecalis biofilm

Braz. oral res. (Online); 30 (1), 2016
Abstract Enterococcus faecalis are gram positive bacteria that can mostly resist endodontic therapy, inducing persistent infection in the root canal system. Endodontic sealers with antimicrobial activity may help eliminate residual microorganisms that survive endodontic treatment. The present study aimed...

Biocompatibility and biomineralization assessment of bioceramic-, epoxy-, and calcium hydroxide-based sealers

Braz. oral res. (Online); 30 (1), 2016
Abstract Obturation of the root canal system aims to fill empty spaces, promoting hermetic sealing and preventing bacterial activity in periapical tissues. This should provide optimal conditions for repair, stimulating the process of biomineralization. An endodontic sealer should be biocompatible once it...
