A biocomplex to repair experimental critical size defects associated with photo...
Buchaim,Daniela Vieira; Andreo,Jesus Carlos; Pomini,Karina Torres; Barraviera,Benedito; Ferreira Júnior,Rui Seabra; Duarte,Marco Antonio HungaroAbstract Background: The association of scaffolds to repair extensive bone defects can contribute to their evolution and morphophysiological recomposition. The incorporation of particulate biomaterials into three-dimensional fibrin bioproducts together with photobiomodulation therapy (PBM) has potential and can improve regenerative medicine procedures. The objective of this experiment was to evaluate the effect...
Prevalence of root canal system configurations in the brazilian population anal...
Silva,Emmanuel J.N.L.; Prado,Marina Carvalho; Duarte,Marco Antonio Hungaro; Versiani,Marco Aurelio; Marques,Duarte; Martins,Jorge N.R.Abstract Objectives: This study performed a systematic review of anatomy prevalence studies using cone-beam computed tomography to comprehend the root and root canal configuration types in Brazilian sub-populations. Methods: This systematic review followed PRISMA’s statements. Four electronic databases (PubMed, ScienceDirect, Lilacs, and Cochrane Collaboration) were accessed using MeSH terms and free-text keywo...
Profile of host cell responses to exposure to stressed bacteria in planktonic; ...
Zancan,Rafaela Fernandes; Ponce,José Burgos; Dionisio,Thiago José; Oliveira,Rodrigo Cardoso de; Silva,Rafaela Alves da; Duque,Jussaro AlvesAbstract The host defense response to microbial challenge emerging from the root canal system leads to apical periodontitis. The aim of this study was to evaluate the expression of inflammatory cytokines and Nitric Oxide (NO) by macrophages after interaction with Enterococcus faecalis in the: plankton and dislodged biofilm mode; intact biofilm mode stimulated by calcium hydroxide (CH), CH and chlorhexidine (CHX...
Can kinematics, file diameter, and PUI influence the intracanal decontamination...
Cuellar,Maricel Rosario Cardenas; Velásquez-Espedilla,Evelyn Giuliana; Pedrinha,Victor Feliz; Vivan,Rodrigo Ricci; Duarte,Marco Antonio HungaroAbstract: The present study investigated the intracanal decontamination and apical extrusion of bacteria and debris from root canals instrumented with rotary and reciprocating systems (ProDesign Logic or ProDesign R), with different file diameters and using conventional syringe irrigation (CSI) or passive ultrasonic irrigation (PUI). Eighty extracted mandibular premolars were contaminated with Enterococcus faec...
Evaluation of type of kinematics on glide path procedures and torsional fatigue...
Alcalde,Murilo Priori; Duarte,Marco Antonio Hungaro; Calefi,Pedro Henrique Souza; Cruz,Victor de Moraes; Vasconcelos,Bruno Carvalho deAbstract: Sixty moderately curved canals of mandibular molars classified as Vertucci’s type IV canal configuration were selected by micro-CT 1174. The teeth were divided into two groups according to the kinematics used, whether reciprocating or rotary motion (n=30, totaling 60 mesial root canals). The instruments used to perform the glide path procedures had identical features (0.15 mm of tip size, 0.04 mm/mm t...
Impact of irrigation protocols with some chelators and mechanical agitation on ...
Pedrinha,Victor Feliz; Cardenas Cuellar,Maricel Rosario; Velásquez-Espedilla,Evelyn Giuliana; Duarte,Marco Antonio Hungaro; Andrade,Flaviana Bombarda deAbstract: This study evaluated main canal and intratubular decontamination using different irrigation solutions followed by adjunctive agitation steps for infected root canals. Sixty-eight lower incisors were contaminated with Enterococcus faecalis and allocated to groups according to canal treatment (n = 10): G1, NaOCl followed by ethylenediaminetetraacetic acid (EDTA); G2, a mixture of NaOCl with hydroxyethyl...
Antimicrobial Activity and Physicochemical Properties of Antibiotic Pastes Used...
Zancan,Rafaela Fernandes; Cavenago,Bruno Cavalini; Oda,Denise Ferracioli; Bramante,Clovis Monteiro; Andrade,Flaviana Bombarda deAbstract: The purpose of this study was to evaluate the pH, solubility and antimicrobial action of Calcium Hydroxide Paste (CH), Double Antibiotic Paste (metronidazole+ciprofloxacin-DAP), calcium hydroxide added to DAP (CH/DAP) and Triple Antibiotic Paste (metronidazole + ciprofloxacin+minocycline-TAP). pH (n=10) were measured by pHmeter. Root canals of acrylic teeth (n=10) were filled with the above-mentioned ...
Debris extrusion and foraminal deformation produced by reciprocating instrument...
Frota,Myrna Maria Arcanjo; Bernardes,Ricardo Affonso; Vivan,Rodrigo Ricci; Vivacqua-Gomes,Nilton; Duarte,Marco Antonio HungaroAbstract Objective To evaluate the amount of apically extruded debris, percentage of foraminal enlargement and apical foramen (AF) deformation that occurred during root canal preparation with different reciprocation systems: Reciproc, WaveOne (M-Wire), and ProDesign R (Shape Memory Technology Wire) at two different working lengths (WLs): 0.0 and 1.0 mm beyond the AF. Material and methods The AF of 120 root cana...
Physicochemical properties of calcium silicate-based formulations MTA Repair HP...
Guimarães,Bruno Martini; Prati,Carlo; Duarte,Marco Antonio Hungaro; Bramante,Clovis Monteiro; Gandolfi,Maria GiovannaAbstract Objective This study aimed to analyze the following physicochemical properties: radiopacity, final setting time, calcium release, pH change, solubility, water sorption, porosity, surface morphology, and apatite-forming ability of two calcium silicate-based materials. Material and methods We tested MTA Repair HP and MTA Vitalcem in comparison with conventional MTA, analyzing radiopacity and final settin...
Do different strains of E. faecalis have the same behavior towards intracanal m...
Zancan,Rafaela Fernandes; Canali,Lyz Cristina Furquim; Tartari,Talita; Andrade,Flaviana Bombarda de; Vivan,Rodrigo Ricci; Duarte,Marco Antonio HungaroAbstract: 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 for 21 days with both bacteria at different time-intervals to ensure there would be no cross contamination. ...
