Materijali i metode: Odabrano je 40 meziobukalnih korijena. Podijeljeni su u četiri skupine po 10 uzoraka: I. skupina – punjenje je uklonjeno sustavom ProTaper Universal RetreatmentTM i otapalom Orange Oilom; II. skupina – korijeni su očišćeni sustavom ProTaper Universal RetreatmentTM i otapalom Eukaliptolom; III. skupina – uporabljene su pilice Hedström i K-proširivači te otapalo Orange Oil; IV. skupna – punjenje je uklonjeno pilicama Hedström i K-proširivačima te otapalom Eukaliptolom. Uzorke su pregledala tri endodonta ne bi li pronašli ostatke materijala za punjenje. Statistička analiza obavljena...

Aim: The purpose of this study was to compare the effectiveness of Ultrasound, CanalBrush and LASER with that of 17% EDTA in the removal of smear layer in the apical third. Methodology: 50 distal roots of the first mandibulars molars with concluded rooting process were accessed and instrumented with the ProTaper Universal System until F5 file. Specimens were assigned to 5 groups (n = 10) and submitted to the following irrigation agitation techniques: control, ProTaper Universal TM files, Ultrasonic, CanalBrushTM and LASER. Root canals were split longitudinally and subjected to scanning electron microscopy. A score system was used to evaluate the images. Data were tabulated and a statistical analysis was realized by using Kruskal Wallis and Mann-Whitney tests with a significance level of 5%. Results: the ultrasound technique showed 56.6% of the specimens with complete removal of the smear layer, and presented the most efficient technique (p<0,005). LASER was less efficient than ul...

INTRODUCTION The aim of this study was to compare the efficacy of the Nd:YAG laser, ultrasound, the ProTaper Universal system (Dentsply Maillefer, Ballaigues, Switzerland), and the CanalBrush (Coltene Whaledent, Langenau, Germany) methods for the removal of the smear layer from the apical third of root canals. METHODS Fifty distal root canals from extracted human mandibular first molars were instrumented up to ProTaper Universal F5 and divided randomly into 5 groups (n = 10) according to the following final irrigation agitation techniques: no agitation (control), ProTaper Universal file, ultrasound, CanalBrush, and Nd:YAG laser. Specimens were observed under a scanning electron microscope. The presence of the smear layer was evaluated using a 3-grade scoring system. The data were analyzed with Cohen kappa, Kruskal-Wallis, and Mann-Whitney U tests. A level of significance of .05 was adopted. RESULTS The ultrasound group performed significantly better than the rest of the groups; 56.6...

Objetivo: relatar a experiencia de institucionalizacao das acoes de integracao entre a formacao para o trabalho do curso de odontologia da UFPE atraves da implantacao do Nucleo de Integracao Ensino Servico-NIES. Metodo: Trata-se de uma analise quanti-qualitativa das acoes referentes a estruturacao do estagio obrigatorio e  preparacao dos alunos, a capacitacao de preceptores, analise de situacao de saude  e intervencao nas comunidades. Resultado: Com o novo perfil implantado em 2010.1, o curso ampliou a carga horaria reservada ao estagio curricular de 150 horas para um cenario de 840 horas divididos em estagio no sistema publico de saude na atencao basica e em servicos especializados. Sobre a insercao de alunos por semestre, nos servicos da rede SUS, houve uma mudanca de 20 alunos no perfil anterior, para 70 nos primeiros momentos da implantacao do perfil; e projecao de 560 quando o novo perfil estiver totalmente implantado. Para viabilizar essa nova dimensao foi proposto e aprovado ...

The objective of this study was to evaluate the influence of Passive Ultrasonic Irrigation (PUI) and Photodynamic Therapy (PDT) on root fracture after root canal filling with AH Plus TM and MTA Fillapex® sealers. Seventy five mandibulars premolars were used, which were instrumented with the Primary file of the Wave One Gold System. The specimens were randomly divided into 3 groups according to the final irrigation technique: 1) EDTA; 2) PUI; 3) PDT. The groups were divided into 3 subgroups, according to the obturator cement used: a) Control; b) AH Plus and c) MTA Fillapex. After filling, the specimens were placed in blocks of acrylic resin and submitted to the compression test. Thus, the maximum compression force of each specimen was recorded, and the data were submitted to ANOVA and Tukey tests. According to the tests, the highest resistance was found in the EDTA + AH Plus association, with an average of 2095N. PDT showed the lowest fracture resistance among the control groups (679...
