In vitro effect of experimental nanocomposites solutions on the prevention of d...
Leite,Karla Lorene de França; Vieira,Thiago Isidro; Alexandria,Adílis Kalina; Silva,Raphael Ferreira da; Silva,Aline Saddock de Sá; Lopes,Ricardo TadeuAbstract This study aimed to evaluate the in vitro effect of a single application of experimental nanocomposite solutions on the prevention of dental caries around orthodontic brackets. The specimens were exposed to mesoporous silica (MS) nanocomposites containing fluoride by association with titanium tetrafluoride (TiF4) or sodium fluoride (NaF). Nanocomposites also could contain calcium and groups were descri...
On the Causality Between Dentinal Defects and Root Canal Preparation: A Micro-C...
De-Deus,Gustavo; Belladonna,Felipe Gonçalves; Marins,Juliana Roter; Silva,Emmanuel João Nogueira Leal; Neves,Aline de Almeida; Souza,Erick MirandaAbstract This study aimed to evaluate the cause-effect relationship between canal preparation with ProTaper Universal (PTU) system and dentinal defects formation using micro-computed tomography (micro-CT) analysis. Forty mesial canals of mandibular molars with a type II Vertucci's canal configuration were scanned at an isotropic resolution of 14.16 µm. The sample was assigned to an experimental (n = 30) and a c...
Postoperative Pain after Foraminal Instrumentation with a Reciprocating System ...
Silva,Emmanuel João Nogueira Leal da; Monteiro,Maria Rachel; Belladonna,Felipe Gonçalves; Almeida,José Flávio; De-Deus,Gustavo; Neves,Aline de AlmeidaThe aim of the present study was to evaluate and compare postoperative pain after foraminal instrumentation using 5.25% sodium hypochlorite (NaOCl) or 2% chlorhexidine (CHX) gel irrigation protocol in nonvital single-rooted teeth after reciprocating instrumentation. Sixty-two volunteers presenting a single root canal diagnosed with asymptomatic necrosis and apical periodontitis were randomized into 2 experiment...
Three-dimensional Quantitative Porosity Characterization of Syringe- versus Han...
De-Deus,Gustavo; Scelza,Miriam Z.; Neelakantan,Prasanna; Sharma,Subash; Neves,Aline de Almeida; Silva,Emmanuel João Nogueira LealThe aim of the present study was to compare the porosity characteristics of AH Plus Jet(tm) syringe-mix and the conventional hand-mixed AH Plus root canal sealers by three-dimensional quantitative high-resolution micro-computed tomography (micro-CT). Seven test specimens were prepared from each tested sealer by a single operator following the manufacturer's instructions and poured into pre-lubricated plastic sp...
Micro-CT Evaluation of Non-instrumented Canal Areas with Different Enlargements...
De-Deus,Gustavo; Belladonna,Felipe Gonçalves; Silva,Emmanuel João Nogueira Leal; Marins,Juliana Roter; Souza,Erick Miranda; Perez,RenataThe aim of this study was to compare the percentage of non-instrumented area of root canals prepared with different enlargements using single-file reciprocating systems (Reciproc and WaveOne) and a conventional multi-file rotary (BioRaCe) system by micro-computed tomographic analysis. Thirty mesial roots of mandibular molars with moderate curvature (10° to 20°) presenting a type II Vertucci canal configuration ...
Evaluation of foraminal transportation during foraminal enlargement with differ...
Silva,Diogo; Gomes,Aline Cristine; Silva,Juliana Melo da; Neves,Aline de Almeida; Zaia,Alexandre Augusto; Silva,Emmanuel João Nogueira Leal daAim: To evaluate the foraminal transportation during foraminal enlargement after manual instrumentation with stainless steel files, preparation with the Mtwo system and Reciproc R25 file. Methods: Thirty roots were selected, divided in three groups and prepared in accordance with the different instrumentation systems: Hand Files (HF); Mtwo system (MS); and Reciproc system (RS). All groups were prepared with the...
