ABSTRACT Introduction: the aim of this study is to evaluate the antimicrobial capacity of silver nanoparticles immobilized in a zinc oxide-eugenol (ZOE) cement against Enterococcus faecalis for potential use in endodontic treatments. Method: experimental in vitro study, performing synthesis of silver...
ABSTRACT BACKGROUND: Colorectal cancer is one of the most commonly diagnosed cancers around the world. One of the factors involved in the development of colorectal cancer is the changes in the normal flora of the intestine. OBJECTIVE: In this study, the mean copy number of Enterococcus faecalis in pe...
Objective: to evaluate antimicrobial action, pH, and tissue dissolution capacity of 2.5% sodium hypochlorite (NaOCl) gel and solution. Methods: The 2.5% NaOCl gel was produced from a colloidal base. The test groups included 2.5% NaOCl gel and solution and the control groups included gel base and distille...
Resumo Introdução O tratamento endodôntico tem como objetivo erradicar microrganismos bacterianos e fúngicos do canal radicular, ou pelo menos possibilitar sua redução para níveis compatíveis com a saúde do tecido perirradicular, uma vez que, após o tratamento endodôntico, colônias de micror...
Resumo Introdução O preparo do canal radicular, em especial o terço apical, é fundamental para o sucesso da terapia endodôntica, pois abriga o forame radicular, local que comunica o endodonto com os tecidos perirradiculares. Objetivo A presente pesquisa avaliou a contaminação do terço apical ap...
O presente estudo teve como objetivo avaliar a atividade antimicrobiana dos cimentos endodônticos, com ou sem associação do uso prévio de hidróxido de cálcio em um modelo “in vitro” de biofilme. Espécimes de dentina bovina (240) foram colocadas e deixas em contato direto com inoculo de E. faec...
Abstract: This study investigated the effectiveness of XP-Endo Finisher (XPF) associated with XP-Endo Shaper (XPS) or Reciproc Blue (RB) files in reducing bacterial load in oval-shaped root canals (RC) during chemomechanical preparation (CMP) using 0.9% saline solution (NaCl) or 2.5% sodium hypochlorite ...

Abstract Objective: To compare the antibacterial efficacy of Cuminum cyminum (cumin) extract and 2% chlorhexidine. Material and Methods: E. faecalis was isolated from non-vital teeth with chronic apical abscess. Samples were then bred in the ChromAgar medium. Subsequently, E. faecalis bacteria's DNA ex...
Abstract Objective The aim of this study was to investigate the cytotoxic effects of modified triple antibiotic paste and an experimental composition using calcium hydroxide on lipoteichoic acid (LTA)-primed apical papilla cells (APC). Material and Methods Human APC were tested for in vitro cytotoxic...
