The clinic based on scientific evidences has never been so mentioned as it is nowadays. Frequently, we testify circumstances in which professionals assume this sort of stance in conferences, courses, classes or even in social media. The platforms, categorized by the number of “followers” and traded “likes”, are dangerously used as means of teaching and learning, as well as sources of conduct establishment. This understanding, however, goes beyond the pertinent speech under the pretext...

My mom was a Normal School (secondary school with teacher training programs) teacher and my father was a farmer, so I learned from a young age to appreciate studying. I was taught to read and write by my mother, Maria Silveira Estrela, who was also my teacher. I attended elementary and high school at Marista School, where I have great memories. I started my academic activities working as a tutor in college, in a tutoring program at the João Paulino Dentistry College, currently...

The achievements incorporated into endodontics, resulting from new information technologies allowed advances that impacted prognosis and clinical success. These new acquisitions have influenced the contemporary world, that is witnessing a profound change brought about by the speed and quality of information, investment savings and time, thus benefiting the health areas. A revolution in contemporary thinking and living that is being experienced today is biotechnology. The impact of cone beam...

Introduction: This study aim to review the literature about the physicochemical and biological characteristics of Biodentine, a cement used in endodontics, and discussed whether this material might be an alternative to MTA according to the scientific evidence found in the literature. Methods: A literature search was performed on PubMed using the following terms: Biodentine, calcium silicate, MTA, properties, setting time, radiopacity, solubility, physicochemical properties, porosity,...

Introduction: Reciprocating system can prepare the root canal using only one instrument. However, to ensure successful endodontic treatment, it must result in high-quality root canal filling. In this regard, several techniques can be used, and it is important that their efficiency is determined. This study analyzed three different techniques in terms of their ability to fill root canal. Material and Methods: The study involved 30 extracted human mandibular molars. Mesial canals of these...

Introduction: The mandibular premolars represent a challenge in endodontic treatment due to their anatomical variations. Thus, cone-beam computed tomography (CBCT) is used for the detailed study of the dental anatomy. Objective: To evaluate dental anatomy of the mandibular premolars using CBCT. Methods: The sample included CBCT images in the coronal, sagittal and axial sections of 200 mandibular premolars. The number of roots, root canals and configuration according to Vertucci were...

Introduction: The practice of endodontics involves of long sessions and repetitive movements during the execution of maneuvers that require considerable effort often in an uncomfortable position. Such factors exert a significant influence on the emergence of symptoms related to musculoskeletal disorders. Methods: Two questionnaires were administered to 25 endodontists in the city of Maringá, Brazil. Data analysis involved Fisher’s exact test with the aid of Statistica 8.0. Results: Pain...

Introduction: Obturation consists of the three-dimensional filling of the root canal system and requires good sealing by the endodontic sealer. In the search for an ideal material the MTA Fillapex has been introduced in the market, which is an MTA-based biocompatible endodontic sealer that still lacks analysis of its physicochemical properties. This study analyzed and compared the sealing provided by sealers MTA Fillapex and AH Plus. Material and method: The study was conducted on 20 human...

Objective: The aim of this study was to characterize the dimensions of the Reciproc R25 and X1 Blue File instruments and the gutta-percha points of Mk Life R25, Reciproc R25 and DiaDent R25 to verify which gutta-percha point better fits to the instruments preparation. Material and methods: Ten Reciproc R25 25/0.08v and X1Blue File 25/0.06 instruments; and ten DiaDent R25, Mk Life R25 and Reciproc R25 gutta-percha points were used. The images were obtained through a stereomicroscopic with a...

Introduction: Endodontic science aims to maintain the dental element in function in the stomatognathic system, through procedures of sanification, modeling and obturation of the root conduits. However, the success of the treatment may be compromised due to the presence of partial or total obliterations of the pulp cavity, which hinder and even impede the procedure. Recently, the technological advance made it possible to transpose these barriers with the creation of a guide that allows...

The aim of this case report was to describe the use of ultrasonic in several endodontics steps during root canal treatment of second C-shaped mandibular molar, favoring more predictable outcome of endodontic treatment of teeth with complex anatomy. A male patient reported painful symptoms on the right and lower side of the face. Clinical examination revealed absence of pulp vitality of tooth 47 and the radiographic examination showed carious lesion, apical periodontitis and C-shaped anatomy....

Objective: This case report shows a successful viable treatment for an endodontically treated permanent mandibular molar which presented clinical symptoms 6 months after the endodontic treatment. Since endodontic retreatment or paraendodontic surgery were not indicated, the chosen technique was intentional replantation. Case Report: One hour before the procedure, the patient rinsed his mouth with chlorhexidine gluconate 0.12%. The patient was prepared for surgery and profound inferior...

Introduction: Immature teeth with pulp necrosis constitute a challenge to endodontic therapy. Our objective was to describe the management of a tooth case of with incomplete rizogenesis and pulp necrosis. Methods: Patient, male, 13-years-old, with a history of dental trauma in the maxillary central incisors. After confirmation of pulp necrosis, the teeth were submitted to calcium hydroxide intracanal and, posteriorly, apicification with MTA and obturation with gutta-percha. Results: After...
