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...
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...
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 ...
Effect of At-Home Bleaching on Oxygen Saturation Levels in the Dental Pulp of M...
Solda,Caroline; Barletta,Fernando Branco; Vanni,José Roberto; Lambert,Paula; Só,Marcus Vinícius Reis; Estrela,CarlosAbstract The present study assessed oxygen saturation (SaO2) levels before, during, and after at-home bleaching treatment in the pulps of healthy maxillary central incisors. SaO2 levels were measured in 136 healthy maxillary central incisors using a pulse oximeter. The bleaching protocol consisted of 10% carbamide peroxide gel placed in individual trays and used for four hours daily for 14 days. SaO2 levels wer...
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...
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...
An in vivo radiographic evaluation of the accuracy of Apex and iPex electronic ...
Paludo,Laura; Souza,Sophia Lopes de; Só,Marcus Vinícius Reis; Rosa,Ricardo Abreu da; Vier-Pelisser,Fabiana Vieira; Duarte,Marco Antônio HúngaroThe aim of this study was to evaluate in vivo the clinical applicability of two electronic apex locators (EALs) - Apex (Septodont) and iPex (NSK) - in different groups of human teeth by using radiography. The working lengths (WLs) of 100 root canals were determined electronically. The EAL to be used first was chosen randomly and a K-file was inserted into the root canal until the EAL display indicated the locat...
