Introduction: The treatment of choice for teeth withcontaminated root portion is endodontic treatment, however,when this treatment fails, it is necessary to retreatthis portion. Paraendodontic surgery is one of the meansof retreatment, which will enable maintenance of the toothin the oral cavity. The push-out technique aims to measurethe shear strength between cement and dentin. Objective:The aim of the present study is to evaluate theadhesion of retro-obturator materials using this...

Objective: To evaluate the success rate of direct pulp capping(DPC) in permanent teeth with complete root formationof patients treated at the Faculty of Dentistry of theUniversity of the Extreme South of Santa Catarina (FOUNESC)between 2014 and 2017. Methods: After consultingthe medical records, 25 teeth with DPC were identified, ofwhich 17 met the inclusion and exclusion criteria. The followingdata were collected: age and sex of the patient, locationof the tooth in the dental arch, and...

Introduction: Scientific data suggest that normal bloodflow and dental pulp sensitivity are impaired in patientsundergoing radiotherapy (RT) to treat oral cancer. Pulseoximeter (PO) emerges as a promising alternative in thedetermination of pulp vitality, giving reliable data for acomprehensive characterization of pulpal status. Objective:The present study aimed at investigating the oxygensaturation (%SpO2) of the dental pulp in patients withoral malignant tumors immediately after RT and 6...

Objective: The aim of this study was to compare cyclic fatigueresistance of heat-treated nickel-titanium (NiTi) reciprocatinginstruments. Materials and Methods: ReciprocatingNiTi instruments with different heat-treatments,ProDesign R 25/.06 (PDR), Reciproc Blue 25/.08 (RB), X1File 25/.06 (X1), WaveOne Gold (WOG) 25/.07 and Unicone25/.06 (UN) were evaluated (n = 12). Cyclic fatigueresistance testing was performed in an artificial stainlesssteel canal with 60° angle of curvature and a 5-mm...

Introduction: Dental avulsion is a highly prevalent publichealth problem. The most predictable management is immediatere-implantation of the avulsed tooth. Objective:The aim of this study was to report a clinical case of avulsionof tooth 21 with late re-implantation within the period of 24hours. Description: The patient, a 9-year-old girl soughtdental assessment at a private clinic. The mother informedthat the child had fallen, and that the avulsed tooth was storedin physiological solution....

Introduction: Currently, a new endodontic technique allowsfor continuous apical development and thickening ofthe root walls. This effect is obtained through the adequatedisinfection of the root canal system, where a natural autologousextracellular matrix is subsequently introducedas an adjuvant to induce apical seal formation. This procedure,called Regenerative Endodontic Therapy (RET), is anoption for the treatment of necrotic teeth with interruptedapex development. Platelet concentrates...

Introduction: The orthograde endodontic retreatmentrequires removing all gutta-percha material. The use ofreciprocating or rotary file systems which has been extensivelyinvestigated in ex vivo studies, reports that it is notpossible to completely remove this material from the rootcanal system. Objective: The objective of this case seriesis to show the importance of operating microscope and ultrasoundto be able to remove the gutta-percha residualthat reciprocating files can leave behind....

Introduction: One of the most common causes thatcan compromise a root canal treatments success is rootcanal perforation. The absence of treatment allows thecontamination of the area by salivary fluids leading to aprogression of the inflammation with destruction of thealveolar bone. According to many factors like location,tooth infection, and accessibility, the dentist needs tomodify the planning and, in many cases, even considersome complementary interventions, like endodonticmicrosurgery...

Objective: The aims of this study are to measure theamount of debris extruded apically and the fracture resistanceof root canals prepared using three different filesystems. Methods and Materials: A total of 120 singlerootedmandibular premolar teeth were divided randomlyinto 4 groups (n = 30 teeth/group). Group 4 served asa positive control for part two of the study. Each groupwas instrumented using one of three different file systems:Twisted File Adaptive (TFA), TruNatomy (TRN), and...

Introduction: Mandibular molars usually have two rootsand three root canals—two in the mesial root (MB and ML)and one in the distal root. They are subject to variations inboth the number of roots and canals. The presence of aMiddle Mesial Canal (MMC), located between the mesiobuccalcanal (MB) and the mesio-lingual canal (ML), hasbeen found in 18.6% of the first mandibular molars. Objective:The present case report describes the retreatment ofa mandibular first molar with inadequate canal...
