The world is going through a moment of questioning in all fields, especiallyin Health, with deep changes in knowledge, teaching, and practice.If, on the one hand, we are faced with a greater demand to follow thedevelopment and the advancement of increasingly complex technologies,on the other hand, we are financially and socially deprived of usingthese resources in an orderly and oriented manner.

When not treated, root canals may affect the predictabilityof endodontic treatments directly. The second mesiobuccalroot canal (2MB) is the canal most often missed andleft untreated during endodontic treatments. The probabilityof inflammatory disease in the periapical region inthese cases is 4.5 to 6.5 times greater than in teeth thathave all canals treated. Therefore, clinical dentists shouldknow the anatomical complexities that may complicateroot canal access and exploration. As 2MB...

Introduction: Rubber dam isolation is a mandatory procedurein dental treatment, especially in Endodontics.However, some professionals still refuse to employ it.Aim: This study interviewed dental professionals, dentalstudents and patients, evaluating the perception of eachgroup concerning the efficacy and safety of rubber damby the percentage of responses to the questions. Methods:The questionnaires were responded by 50 studentsof the last year of Dentistry course at Unipar, 50...

Objective: The present study compared three systemsof thermally treated NiTi endodontic files regarding theirachieved number of prepared root canals before fracture.Methods: Two hundred and ten slightly and moderatelycurved upper and lower molars with actual length rangingfrom 19 to 21 mm and apex foramens diameters up to 200μm were used. The sample was allotted to three groupsaccording to the instrumentation system in use: Reciproc(REC; R25), ProDesign Duo Hybrid (PDH; #25/.01 and#25/.08),...

Objective: To evaluate the influence of different protectionplugs over the remaining obturation after post spacepreparation, on cast metal post retention. Methodology:Fifty bovine teeth were decoronated and root canalswere manually instrumented up to a Kerr 80 file and thenobturated. A Largo drill was used to partially clear the canalat a 10mm depth. Groups were divided, according todifferent plug materials (n=10): Group I (control, with noplug), Group II (Coltosol® plug), Group III...

Objective: The aim of present study was to evaluate theinfluence of alloy (conventional NiTi and M-Wire NiTi)and movement (reciprocating movement and continuousrotation) on resistance to cyclic fatigue. Methods: FifteenReciproc R25 files (VDW GmbH, Munich, Germany)were used in reciprocation motion (RM), while thirtyMTwo 25/.07 files (VDW GmbH, Munich, Germany) wereused either in RM (n=15) or in continuous rotation (CR)(n=15). The files were submitted to dynamic assays devicemoved by electric...

Introduction: The success of endodontic therapy dependsnot merely on their efficacy and proper completion but also onminimal patient discomfort. The purpose of this systematic reviewand meta-analysis is to evaluate the risk and intensity ofpost instrumentation endodontic pain in adult patients. Methods:A comprehensive search was performed in the MEDLINEvia PubMed, Scopus, Web of Science, LILACS, BBOand Cochrane Library and SIGLE without restrictions. Theannual conference of the IADR...

Introduction: The aim of this study was to evaluate thecyclic and torsional fatigue resistance of reciprocatingsingle-file systems W File 25.07 (WF, TDKaFile, MexicoCity, Mexico) and X1 Blue File 25.06 (X1 BF, MK Life,Porto Alegre, Brazil) at body temperature. Materials andMethods: Forty reciprocating instruments of the W File25.07 (WF 25.07) and X1 BF 25.06 (n=20) were used. Cyclicfatigue tests were performed at body temperature (36°± 1°C). The instruments were reciprocated until...

Introduction: Parendodontic surgery is an alternativeto conventional endodontic treatment, especiallyin cases involving periradicular lesions associated withosteolytic processes, in which conventional endodontictherapy or retreatment was not successful. New therapeuticmethods for the treatment of these cases haveground in clinical dentistry . For example, leukocyteandplatelet-rich fibrin which has a higher concentrationand more prolonged release of growth factors, modulatesthe repair...

Introduction: Internal root resorption is the progressivedestruction of intraradicular dentin as a result of clastic activities.It is usually asymptomatic and discovered by chance onroutine radiographic examinations. Is of vital importance tomake a correct diagnosis so that the appropriate treatmentcan be provided because in some cases can result in destructionof the dental element. Objective: The aim of this studyis to report a case of successful non-surgical management ofperforating...

Introduction: periapical cysts are classified as inflammatory,odontogenic cysts; periapical lesions are themost common lesions in the oral cavity. These lesionsare asymptomatic; radiographically, they present radiolucent,unilocular, well-defined images and they surroundthe apices of devitalized teeth. To correctly diagnosea periapical cyst it is also necessary to performa histopathological examination. Methods: the presentstudy describes the clinical case of a twelve year-old femalepatient...

Introduction: Accidents and complications may happenat any endodontic treatment stage. These are likely tochange the prognosis of treatment and can be due to factorsrelated to instrumental failure, anatomic difficulties andthe professional’s limitations. Objective: This case reportaddresses a case where a patient presenting two separatedinstruments and a root perforation in a lower molar withapical periodontitis. Case report: The separated instrumentshave been removed by mechanical and...
