Introduction: Acute Renal Failure (ARF) occurs in about5% of hospitalizations and up to 30% of ICU admissions,with mortality rates between 15% and 60%. The objectiveof this study was to analyze different protocols forthe induction of IRA in an animal model, seeking thestandardization of the model for the study of bidirectionalrelationship with apical periodontitis (AP). Methods:Twenty-four rats were divided into three groups (n = 8):G1 - Administration of Gentamicin at a dose of 80mg/kg/day...
In the last 50 years of endodontics life, significant changes occurred towardshealth promotion for patients, with elimination of infections, and at the same time,maintaining teeth in the oral cavity. This fact represents an important judgment withinthe analysis of factors for the evolution of a specialty in the area of human health.Scientific advances in basic areas have allowed deeper and better understandingof the phenomena that involve the processes of aggression and defense withinthe...
What led you to doing your Master’s Degreein Oral Physiology, and more specifically, specializingin the area of TMD and Orofacial Pain?In December 1997, after concluding my graduation inDentistry, still a little “lost” and insecure with regard tomy professional future, one of my mother’s sisters (AuntSilvinha) and her husband (Uncle Douglas), residentsin Piracicaba, sparked in me the idea of transferringresidence to their home, as there were greater possibilitiesof continuing and...
Introduction: The maintenance of natural dentition ispreferable in most of cases. However, nowadays it ispossible to use dental implants in cases where prognosisis very limited. Endodontics and all of its therapeutic modalitiesplay an important role, which has, in principle, toprevent or eliminate apical periodontitis providing betterconditions for wound healing of periapical and bone tissues.In the past few years, with technological advances,root canal treatment became more predictable and...
Introduction: Root canal fillings and intraradicular postsoften create white contrast artifacts and possible volumetricchanges on CBCT scans known as blooming artifacts.These alterations could lead to the incorrect interpretationsreducing the diagnostic of an acquired CBCT volume,particularly when evaluating potential root fracturesand root perforations. Methods and Results: In sixclinical cases, the positive and negative effects of beamhardening artifacts on the diagnosis of root fractures,...
Introduction: Intraradicular posts are recommended toimprove the retention of artificial crowns and to distributeintraoral forces along the root. If the space created bypartially removing the obturation is not adequately filled,it can lead to a massive infiltration of microorganismsfrom the oral cavity. Aim: The aim of this study was toassess the influence on bacterial infiltration of an intracanalbarrier placed directly over the remaining root canalfilling following post space preparation....
Background: The elimination of Enterococcus faecalisof the root canals is fundamental for endodontic success,since these microorganisms are difficult to killed, especiallywhen organized in biofilms. The search for drugsor their combinations that can eliminate these microorganismsis one of the main therapeutic aim. This studyevaluated the antimicrobial action of experimental intracanalmedications on Enterococcus faecalis biofilms.Methods: Forty uniradicular bovine teeth were used;their crowns...
Objective: This study used micro-CT to evaluate theamount of remaining filling material in curved root canalsobturated with Endosequence BC Sealer/Cpoint orAH/gutta-percha after a rotary or reciprocating retreatment.Methods: Sixty mesiobuccal canals of maxillarymolars were instrumented up to MTwo #35.04. Sampleswere randomly assigned to four groups (n=15): canalsfrom G1 and G2 were filled with AH/gutta-percha, andcanals from G3 and G4 were filled with BC/Cpoint. Fillingmaterial was removed...
Objective: To identify the main causes of odontogenicpain that lead to people search for care in the UrgencyService of the School of Dentistry of University, PassoFundo/RS/Brazil (SPAOH), localized in the Hospital SãoVicente de Paulo. Methodology: A cross-sectional andretrospective study, carried out between the period fromNovember 1, 2016 to October 31, 2017, when data fromdental care records were collected and tabulated. Thedata were analyzed looking for the prevalence of severalcauses of...
This study aimed to assess three final irrigation protocolson debris and filling removal from simulated irregularities.Methods: Seventy-eight mandibular premolarswere prepared with WaveOne Gold system 45.05, splittedlongitudinally, and a standardized groove was performedin the apical portion of the canals. Six roots served asnegative control. The roots were randomly divided intotwo main groups (n = 36). The grooves were filled withdentin debris in thirty six roots. The others thirty-six...
Introduction: Glass fiber posts are widely used whenendodontically treated teeth present great structural lossand require support for coronal reconstruction. Completeadhesion of the post to the root canal wall is fundamentalfor the success of this restoration. Endodontic sealerresidues that remain on the dentin walls, even after preparationfor cementation, may negatively interfere with theadhesion and contribute for post displacement. This literaturereview evaluated the effect of different...
Introduction: Identification of possible anatomical variationsis crucial for the correct diagnosis and planning ofendodontic therapy. Objective: To report the endodontictreatment of tooth #37, in which a third canal was locatedin the mesial root (middle mesial canal - MMC).Methods: Tooth #37 was diagnosed with symptomaticirreversible pulpitis and referred for endodontic treatment.Coronary cracks were found during coronal access usinga dental operating microscope (DOM). A cone-beamcomputed...
Introduction: The aim of this study was to evaluate thecrown discoloration after root canal filling with differentendodontic cements clinically. Methods: Thirty-two teethwere endodontically treated and filled with AH Plus (AHP),Endofill (END), MTA Fillapex (MTA), or Sealer 26 (SEA),divided into eight patients per group. Color recording wasperformed with a spectrophotometer before the intervention(T0) and at 30 (T1) and 90 days post-intervention (T2).The evaluations were done in the center of...
