Efeito da ativação ultrassônica da pasta de hidróxido de cálcio na atividade metabólica de bactérias em canais radiculares: Estudo clínico randomizado

Protocolos complementares de desinfecção estão sendo investigados com o objetivo de promover uma maior redução de bactérias viáveis após o preparo químico-cirúrgico dos canais radiculares. Este estudo clínico randomizado comparou o efeito da ativação ultrassônica da pasta de hidróxido de c...

Avaliação microbiológica de um protocolo de tratamento endodôntico utilizando procedimentos complementares de desinfecção após o preparo químicocirúrgico em dentes com periodontite apical

Procedimentos clínicos complementares realizados após o preparo químico-cirúrgico de canais radiculares visam potencializar a limpeza e desinfecção após a fase de preparo. O objetivo deste trabalho foi avaliar, por métodos moleculares baseados em rDNA e rRNA, a eficácia antimicrobiana de procedi...

Root perforations: a review of diagnosis, prognosis and materials

Braz. oral res. (Online); 32 (supl.1), 2018
Abstract: Root perforation results in the communication between root canal walls and periodontal space (external tooth surface). It is commonly caused by an operative procedural accident or pathological alteration (such as extensive dental caries, and external or internal inflammatory root resorption). D...

Do different strains of E. faecalis have the same behavior towards intracanal medications in in vitro research?

Abstract: The aim of this study was to evaluate the antimicrobial action of different endodontic pastes against Enterococcus faecalis ATCC 29212, isolated from the urinary tract, and compare the action with E. faecalis ATCC 4083, isolated from the root canal. For this purpose, dentin blocks were infected...

Immediate tooth replantation: root canal filling for delayed initiation of endodontic treatment

Abstract The aim of this study is to evaluate the action of paramonochlorophenol associated with Furacin followed by calcium hydroxide (CH) dressing in the control of inflammatory root resorption in cases of immediate tooth replantation with delayed endodontic treatment. A total of 28 incisors of 3 male ...

Effects of mineral trioxide aggregate, BiodentineTM and calcium hydroxide on viability, proliferation, migration and differentiation of stem cells from human exfoliated deciduous teeth

J. appl. oral sci; 26 (), 2018
Abstract Objective: The aim of the study was to evaluate the effects of the capping materials mineral trioxide aggregate (MTA), calcium hydroxide (CH) and BiodentineTM (BD) on stem cells from human exfoliated deciduous teeth (SHED) in vitro. Material and Methods: SHED were cultured for 1 - 7 days in me...

Factors affecting the periapical healing process of endodontically treated teeth

J. appl. oral sci; 25 (5), 2017
Abstract Tissue repair is an essential process that reestablishes tissue integrity and regular function. Nevertheless, different therapeutic factors and clinical conditions may interfere in this process of periapical healing. This review aims to discuss the important therapeutic factors associated with t...

Antibacterial activity of intracanal medications based on calcium hydroxide and zinc oxide micro- or nanoparticles: an ex vivo study

Introduction: Nanoparticles and associations to calcium hydroxide can be used to increase antimicrobial activity. Objective: To evaluate antibacterial activity against Enterococcus faecalis and pH of intracanal medications (IM) based on calcium hydroxide (CH) and zinc oxide (ZnO) micro- or nanoparticles...

Effectiveness of various irrigation protocols for the removal of calcium hydroxide from artificial standardized grooves

J. appl. oral sci; 25 (3), 2017
Abstract Objective The aim of this study was to investigate the ability of laser-activated irrigation (LAI), XP-endo Finisher, CanalBrush, Vibringe, passive ultrasonic irrigation (PUI), and conventional syringe irrigation systems on the removal of calcium hydroxide (CH) from simulated root canal irregu...

Analysis of pH and release of calcium of association between melaleuca alternifolia oil and calcium hydroxide

Introduction: The use of intracanal medications with antimicrobial properties is essential for decontaminating root canals during endodontic treatment. Calcium hydroxide is used for this because of its excellent properties. Melaleuca alternifolia oil has shown medicinal importance by demonstrating antifu...
