Dentinal Tubule Penetration of a Calcium Silicate-Based Root Canal Sealer Using...
Coronas,Viviane Siqueira; Villa,Natália; Nascimento,Angela Longo do; Duarte,Pedro Henrique Marks; Rosa,Ricardo Abreu da; Só,Marcus Vinícius ReisAbstract This study aimed to evaluate penetrability on dentinal tubule of a new bioceramic sealer through confocal laser scanning microscopy (CLSM). A specific fluorophore (Fluo-3) was mixed with the sealer. Forty distobuccal roots from maxillary molars were selected, and root canal preparation was carried out with Wave One Gold # 35.06 instruments. Roots were randomly assigned to 4 groups according to the fill...
A New Calcium Silicate-Based Root Canal Dressing: Physical and Chemical Propert...
Villa,Natália; Santos,Vanessa Valgas Dos; Costa,Ubirajara Maciel da; Mendes,Aline Teixeira; Duarte,Pedro Henrique Marks; Rosa,Ricardo Abreu daAbstract The aims of this study were to evaluate the physical and chemical properties, cytotoxicity and dentinal tubule penetration of a new calcium silicate-based root canal dressing. For pH and calcium ion release evaluation (1, 24, 72 and 168 h) were used a pH meter and colorimetric spectrophotometer, respectively. Radiopacity evaluation followed the ISO 6876:2012. Cytotoxicity was evaluated by the percentag...
Effect of Post-Space Irrigation with NaOCl And CaOCl at Different Concentration...
Seballos,Vivian Gehm; Barreto,Mirela Sangoi; Rosa,Ricardo Abreu da; Machado,Eduardo; Valandro,Luiz Felipe; Kaizer,Osvaldo BazzanAbstract The aim of this study was to evaluate the effect of post-space irrigation with NaOCl and CaOCl at different concentrations on the bond strength of posts cemented with a self-adhesive resin cement. Eighty premolars were sectioned 14 mm from the apex, and endodontically treated. The root canal filling was partially removed. Specimens were randomly assigned into 8 groups (n=10), according to the irrigant ...
Evaluation of Physicochemical Properties of New Calcium Silicate-Based Sealer
Mendes,Aline Teixeira; Silva,Paula Barcellos da; Só,Bruna Barcelos; Hashizume,Lina Naomi; Vivan,Rodrigo Ricci; Rosa,Ricardo Abreu daAbstract This study aimed to evaluate the physicochemical properties of a calcium silicate-based sealer (Sealer Plus BC; MK Life, Porto Alegre, Brazil) compared with an epoxy-resin sealer (AH Plus; Dentsply DeTrey GmbH, Konstanz, Germany). Initial and final setting time was assessed based on ISO 6876:2012 and ASTM C266:03. Calcium ion release and pH were evaluated by filling polyethylene tubes with sealers and ...
Comparison of two combinations of opioid and non-opioid analgesics for acute pe...
Santini,Manuela Favarin; Rosa,Ricardo Abreu da; Ferreira,Maria Beatriz Cardoso; Fischer,Maria Isabel; Souza,Erick Miranda; Só,Marcus Vinícius ReisAbstract Acute periradicular abscess is a condition characterized by the formation and propagation of pus in the periapical tissues and generally associated with debilitating pain. Objective: The aim of this study was to compare the overall analgesic effectiveness of two combinations of opioid and non-opioid analgesics for acute periradicular abscess. Material and Methods: This study included 26 patients who so...
Micro-CT Evaluation of Root Filling Removal after Three Stages of Retreatment P...
Rosa,Ricardo Abreu da; Santini,Manuela Favarin; Cavenago,Bruno Cavalini; Pereira,Jefferson Ricardo; Duarte,Marco Antônio HúngaroThe aim of this study was to quantify the residual filling material after filling removal, re-preparation with rotary or reciprocating files and passive ultrasonic irrigation (PUI). Twenty maxillary molars were prepared using ProTaper instruments up to F1. The teeth were filled with AH Plus and ProTaper gutta-percha points using the single-cone technique. Thereafter, the specimens were scanned using a micro-com...
Canal Preparation and Filling Techniques do not Influence the Fracture Resistan...
Santini,Manuela Favarin; Rippe,Marília Pivetta; Franciscatto,Gisele Jung; Rosa,Ricardo Abreu da; Valandro,Luiz Felipe; Só,Marcus Vinícius ReisThe purpose of this study was to assess the fracture resistance of extensively damaged teeth after two root canal preparation techniques (hand and rotary files) and after two filling techniques (active and passive compaction). Sixty-eight maxillary canines roots with an apical diameter equal to that of a #25 K-file were embedded in acrylic resin and the periodontal ligament was simulated by using a polyether im...
Influence of Endodontic Sealer Composition and Time of Fiber Post Cementation o...
Rosa,Ricardo Abreu da; Barreto,Mirela Sangoi; Moraes,Rafael do Amaral; Broch,Juliana; Bier,Carlos Alexandre Souza; So,Marcus Vinicius ReisThis study aimed to assess the influence of the type of endodontic sealer (salicylate resin-based sealer vs. two endodontic sealers) and the time of fiber post cementation after root filling on the post adhesion to bovine root dentin. Sixty bovine roots were assigned to six groups (n=10), considering an experimental design with two factors (factorial 3x2): endodontic sealer factor in three levels [epoxy resin-b...
Wizard CD Plus and ProTaper Universal: analysis of apical transportation using ...
Giannastasio,Daiana; Rosa,Ricardo Abreu da; Peres,Bernardo Urbanetto; Barreto,Mirela Sangoi; Dotto,Gustavo Nogara; Kuga,Milton CarlosOBJECTIVE: This study has two aims: 1) to evaluate the apical transportation of the Wizard CD Plus and ProTaper Universal after preparation of simulated root canals; 2) to compare, with Adobe Photoshop, the ability of a new software (Regeemy) in superposing and subtracting images. MATERIAL AND METHODS: Twenty five simulated root canals in acrylic-resin blocks (with 20º curvature) underwent cone beam computed to...
Adhesion of real seal to human root dentin treated with different solutions
Baldissera,Renata; Rosa,Ricardo Abreu da; Wagner,Márcia Helena; Kuga,Milton Carlos; Grecca,Fabiana Soares; Bodanezi,AugustoThe aim of this study was to evaluate the effects of different irrigants on sealer-dentin bond strength when using Real Seal. Thirty single-rooted teeth were divided into 3 groups. In one group, the teeth were irrigated with 3 mL of 2.5% NaOCl after each file change, flushed with 17% EDTA for 3 min and finally rinsed with 3 mL of 2.5% NaOCl. In the other two groups, rinse with NaOCl was replaced with 2% chlorhe...
