Schools of Dentistry are responsible for the scientific, clinical and humanistic education, training and preparation of students to work as confident and responsible dentists. In the last decades, several instruments and materials have been developed to facilitate endodontic treatments. Changes have been drastic, and a very large knowledge base has been built for the dental student. However, these developments have not been accompanied by changes in Endodontics curricula or the number of...

I was born in Lins, SP. I am the son of Mario Tanomaru (in memoriam) and Hissae Tanomaru. I studied at a public school up to high school level, and then at the Objective College. I graduated at the School of Dentistry of Bauru - USP (1984 – 1987). Soon after graduation, I was approved for Endodontic Residency at the Hospital for Rehabilitation of Craniofacial Anomalies (HRAC / Centrinho), USP / Bauru. In 1989, I started the Master’s program in the area of Endodontics at Bauru School of...

Introduction: Even when the most stringent endodontic treatment and/or retreatment are followed, apical periodontitis can persist, leading to periodontal ligament (PDL), cementum, alveolar bone and dentine destruction. In these cases, surgical endodontic treatment, if performed using the operating microscope (OM), minimal root resection, ultrasonic root end preparation and biocompatible root end filling materials, can achieve a success rate of more than 90%. Endodontic surgical procedures...

Introduction: Traumatic injuries may result in pulp necrosis in immature permanent teeth. Objective: This study aimed at evaluating the clinical and radiographic procedures for treatment of the non-vital immature teeth after apexification. Material and Method: This is a cross-sectional study that used the medical records of a center of reference in dental trauma, from 2005 to 2015. Thirty permanent teeth with pulp necrosis and open apex were included in this study whose treatment adopted was...

Introduction: The aim of the present study was to evaluate the cyclic and torsional fatigue resistance of WA1 and WaveOne Gold instruments. Methods: Twenty instruments of the WA1 system (25/0.07v) and twenty instruments of the WaveOne Gold system (25/0.07v) were used. The cyclic fatigue resistance was tested by measuring the time to fracture in a stainless steel curved artificial canal with an angle of 80° and a radius of curvature of 3 mm (n = 10). The maximum torque and rotation angle at...

Introduction: This study evaluated the effect of different final irrigation protocols using EDTA and QMix on smear layer removal. Methods: The root canals of 40 single-rooted human teeth were prepared with ProTaper Universal SX - F3. The substances used were 5.25% sodium hypochlorite (NaOCl), 2% chlorhexidine gel (chlorhexidine), 2% chlorhexidine solution and distilled water. The teeth were divided into 8 groups, according to the irrigant used: G1: 5.25% NaOCl + 17% EDTA + 5.25% NaOCl; G2:...

Objective: The present study evaluated the residues (debris) incidence in dentin fiber post space submitted to irrigation protocols using distilled water (DW), 2.5% sodium hypochlorite (HS), 2.5 % sodium hypochlorite and 17% EDTA (HSE), or 2.5% sodium hypochlorite energized by passive ultrasonic irrigation (HSUS). Methods: Forty bovine incisors root canals with standardized root length (17.0 mm) were obturated using single cone technique and epoxy resin sealer. After 7 days, the fiber post...

Introduction: Chlorhexidine demonstrates effective results in endodontics as an irrigation substance, or as an intra-canal medication. Aim: The aim of this study is to review the literature about the properties of chlorhexidine, emphasizing new findings about the use of this substance as an intra-canal medication, and as an irrigation substance. Methods: Thus, a search was performed on the online databases Bireme and Google Scholar using the keywords irrigation substances, chlorhexidine, and...

Introduction: Endodontic treatment aims to clean and shape the root canal system. Chemomechanical preparation and tridimensional (3D) filling of the root canal system are based on knowledge of internal dental anatomy. Conventional and periapical digital radiographs present limitations in image definition due to the tridimensional anatomy of the tooth to be treated. The 3D anatomy is compressed in a two-dimensional image. Cone-beam computed tomography (CBCT) is currently an interesting tool...

The objective of this article was to report a clinical case of finding a fractured instrument and over-extended guttapercha of a tooth, which were removed via the canal. The patient, a 38-year-old man, was referred for treatment of the right maxillary lateral incisor (tooth 7). The patient presented pain on palpation at the apical level and absence of spontaneous symptomatology. Radiographic examination revealed the presence of a over-extended gutta-percha cone, a fractured Lentulo spiral...

Introduction: Photodynamic therapy appears in endodontics as a treatment method that uses low level laser therapy with analgesic, anti-inflammatory and antibacterial. Goal: This paper aims to present and discuss through an endodontic treatment using photodynamic therapy as an ally against persistent bacteria after chemical-mechanical canal preparation. Case report: GR patient, 40, appeared in private practice, with throbbing pain, sensitive to shock, with acute apical periodontitis, the...

Introduction: Endodontic treatment in teeth with calcified root canals is extremely challenging. During the procedure of locating the root canal, an excessive amount of residual dentin can be removed, which may lead to a greater risk of tooth fracture. In addition, pulp calcification is the most common reason for root perforation during endodontic treatment. Methods: Considering the importance of developing safe and efficient techniques for endodontic treatment of partially or completely...

Introduction: Dens invaginatus is a rare dental anomaly characterized by invagination of dental tissues, which may be from a slight increase in the pit of the cingulum to a deep groove that may extend to the tooth apex. This report describes clinical and radiographic findings and the morphology of a completely atypical and unique anomaly, and discusses the difficulties in the diagnosis and endodontic treatment of the root canal of teeth with this complex anatomy. Clinical case: Patient seen...
