Technology has brought a series of advantages to contemporarylife and has simplified several daily practices, including those inthe healthcare area. In Dentistry, several resources have streamlinedprocedures and allowed for greater precision, quality andspeed when used effectively.

Florid cemento-osseous dysplasia is a sclerosing bonedisease that affects the alveolar process of the jawbones.In most cases, it involves the mandible bilaterally, but mayaffect three and even all four quadrants. If bacteria commonin the oral microbiota and in the root canals reachthe bone affected by florid cemento-osseous dysplasia,this disease may very likely progress to secondary osteomyelitisand result in extensive mandibular destructionand bone loss. Patients with florid...

Introduction: To perform endodontic treatment of adequatequality, it is necessary for professionals to have knowledge ofdental anatomy, effective techniques and filling material withchemical, physical and biological properties to provide satisfactoryprognosis. One of these properties is radiopacity. Theaim of this study was to evaluate the radiopacity of AH Plusendodontic sealer with addition of MTA or Portland cementat different proportions. Methods: The following specimenswere prepared:...

Objective: The aim of this study was to evaluate the influenceof calcium hydroxide medications on root fractureresistance of simulated immature teeth. Methods: Sixtybovine teeth were decoronated, had root canals preparedwith #45-80 K-files, and were irrigated with sodium hypochlorite(1%). Tooth apexes were amplified with type-703drills to simulate incomplete root formation, standardizingthe foramen diameter at 2.1 mm. Roots were embedded inblocks of acrylic resin and divided into three...

Objective: The aim of this study was to evaluate root canalpreparation of two nickel-titanium (NiTi) rotary systems(BioRaCe, FKG, Switzerland and AlphaKite, Komet, Germany)using micro-computed tomography (Micro-CT). Materialand Methods: A total of 20 maxillary first molars, extractedfor periodontal and prosthetic reasons, were dividedinto two groups (n = 10) and scanned by SkyScan 1172.Root canals were irrigated with 2.5% NaOCl between eachfile change, the root canal preparation was...

Introduction: Endodontic surgeries contribute to theresolution of complications resulting from conventionalendodontic treatment. Root resection, a type of endodonticsurgery, consists of partial root removal followed bycanal preparation and filling with adequate material. Incase of perforations, mineral trioxide aggregate (MTA)has often been used for retrograde sealing of the rootcanal, which prevents microorganism infiltration and byproducts.Moreover, MTA is a biocompatible materialthat adheres...

Introduction: Tooth length measure is important to endodontictreatment success. Objective: This in vitro study wasconducted to compare the ability of three electronic deviceswhen measuring foramen and apical contrition. Methods:One hundred human single-rooted teeth were used to havedirect measurement (tooth length) performed by inserting thefile into the root canal until its tip was visualized in the apicalforamen. Measurement by apex locators (Neosono Ultima EZ,Foramatron IV e Tri Auto ZX)...

Diabetes mellitus (DM) is the third most prevalent conditionin patients with systemically compromised health. Inview of the above, the objective of this study was to verifythe implications of DM in patients who require endodontictreatment. To this end, an exploratory research was carriedout through a literature review of articles publishedbetween 2003 and 2016. It can be verified that approximately3 to 4% of adults who undergo dental treatmentare diabetic. These are predisposed to chronic...

Introduction: Although we have promising methods forcleaning and disinfecting in Endodontics, none of themhave yet been able to completely eliminate microorganismspresent in the root canal system. The advent of lasertherapies, associated with specific dyes, has shown promisingresults in reducing root canal microbiota. Objective:The aim of this study was to evaluate the antimicrobial actionof photodynamic therapy (PDT) associated with methyleneblue photosensitizer, as complementary to...

Objective: To evaluate the effectiveness of complementaryprotocols of sanitization in decontamination of infectedroot canals. Methods: A total of 50 single-rooted maxilaryanterior human teeth were selected. The crowns were removedand lengths standardized at 16 mm. The specimenswere inoculated with Enterococcus faecalis and incubatedat 37 °C for 60 days. Thirty teeth were prepared with Bio-Race instruments up to diameter corresponding to #60.02,and then complemented with Self-Adjusting File...

Objective: To evaluate decontamination of root canalsinfected with reciprocating instruments, 2.5% sodium hypochloriteand apple vinegar. Methods: A total of 50 single-rooted human teeth were emptied and contaminatedwith Enterococcus faecalis for 60 days. After the periodof contamination, root canal preparation was performedwith instruments, including: 1. WaveOneTM 40.08 (n = 10);2. ReciprocTM 40.06 (n = 10); and 3. UniconeTM 40.06 (n= 10). Two control groups were used: positive control (n=...
