Analysis of pH and antimicrobial activity of a new bioceramic intracanal medica...
Viana, Francisca Lívia Parente; Sampieri, Marcelo Bonifácio da Silva; Viana, Priscilla Parente; Cruz, Suyane Maria Luna; Vivan, Rodrigo RicciIntracanals medications with antimicrobial activity are important as adjuvants in disinfecting the root canal system. Therefore, this study evaluated, in vitro, the pH and antimicrobial activity of a new bioceramic intracanal medication (Bio-C Temp) compared to calcium hydroxide (HC) medications. The determination of pH was carried out by means of a pH meter in the periods of 30 minutes, 3, 24, 72 and 168 hours...

Penetration of bioceramic and epoxy-resin endodontic cements into lateral canals
Candeiro, George Táccio de Miranda; Lavor, Amanda Bezerra; Lima, Ilana Thaís de Freitas; Vasconcelos, Bruno Carvalho de; Gomes, Nilton VivacquaThe aim of the present study was to assess the penetration capacity of two endodontic cements, Endosequence BC Sealer and AH Plus, in artificial lateral canals. Twenty-six two-rooted, maxillary first premolars were instrumented to size 40.06 using K3 files. In each root, six lateral canals of two diameters (0.06 and 0.10 mm) were created with a working length of 2, 4, and 6 mm. The specimens were randomly divid...

Frota, Myrna Maria Arcanjo; Bernardes, Ricardo Affonso; Vivan, Rodrigo Ricci; Vivacqua-Gomes, Nilton; Duarte, Marco Antonio HungaroObjective: 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 canals in 6...

Influence of NiTi alloy on the root canal shaping capabilities of the ProTaper ...
Duque, Jussaro Alves; Vivan, Rodrigo Ricci; Cavenago, Bruno Cavalini; Amoroso-Silva, Pablo Andrés; Duarte, Marco Antonio HungaroObjective This study aimed to evaluate the influence of the NiTi wire in Conventional NiTi (ProTaper Universal PTU) and Controlled Memory NiTi (ProTaper Gold PTG) instrument systems on the quality of root canal preparation. Material and Methods Twelve mandibular molars with separate mesial canals were scanned using a high-definition microcomputed tomography system. The PTU and PTG instruments were used to shape...
Root ZX electronic foramen locator: an ex vivo study of Its three models’ preci...
Aguiar, Bernardo Almeida; Reinaldo, Rafael Santos; Frota, Luciana Maria Arcanjo; Vale, Mônica Sampaio do; Vasconcelos, Bruno Carvalho deAlthough Root ZX is considered the gold standard electronic foramen locator (EFL), two variations of this device were launched, however without different operating mechanisms.This investigation aims to evaluate the precision of Root ZX (RZX), Root ZX II (RII), and Root ZXMini (RM) EFLs. After access cavity preparation, 32 mandibular single rooted human premolars had their real length measured with the aid of a ...
