For CFU/ml analysis, eight teeth were contaminated for 1 h or 30 days (n=4). Teeth were decontaminated with 5% NaOCl, 2% CHX, or distilled water. As control, no decontamination was conducted. After decontamination, sterile paper points were used to collect samples, and CFU/ml were counted. For push-out, three groups were evaluated (n=15): irrigation with 2.5% NaOCl, 2% CHX, or sterile distilled water. A bonding agent was applied to root canal dentin, and a JODVV¿EHU SRVW ZDV FHPHQWHG ZLWK D GXDOFXUHG FHPHQW $IWHU K PPWKLFN VOLFHV RI the middle portion of root canals were obtained and submitted to the push-out evaluation. Three specimens of each group were evaluated in scanning electron microscopy (SEM). Data were analyzed with one-way ANOVA and Dunnett's T3 test (D=0.05). Results: The number of CFU/ml increased from 1 h to 30 days of contamination in control and sterile distilled water groups. Decontamination with NaOCl was effective only when teeth were contaminated for 1 h. CHX was effective at both contamination times.

Objective: To analyze the antimicrobial action of Endofill, Sealer 26, AHPlus and Acroseal endodontic sealers. Material and methods: Evaluation was made by Agar diffusion method in plates previously inoculated with the following microorganisms: E. coli, E. faecalis, B. cereus and S. aureus. The zones of inhibition were measured after 48 hours of incubation at 37°C. Results: Acroseal sealer showed no antimicrobial activity against E. coli and E. faecalis and it showed moderate activity against B. cereus and S. aureus; AHPlus and Endofill showed high activity mainly against E. coli; Sealer 26 showed moderate activity against all of the microorganisms used. Conclusion: The majority of endodontic sealers have showed antimicrobial activity against the microorganisms used. AHPlus and Endofill sealers were th...

Participaram 144 estudantes, dos turnos matutino e noturno, entre maio e junho de 2016. Destes, 80,6% eram do gênero feminino e 68,5% do turno da manhã. A média de idade foi de 22,94 anos e a mediana de notas na disciplina foi de 6,52. Os estilos predominantes foram sensorial, visual, ativo e sequencial, respectivamente. A correlação entre idade e turno, e a intensidade de cada estilo de aprendizado não tiveram diferença estatisticamente significativa (p ˃ 0,05). As mulheres foram mais sensoriais e os homens mais visuais (p = 0,010). Na correlação entre média anual e estilos, houve diferença significativa para o sensorial e o intuitivo (p < 0,001).

Methods: Hybrid ceramic (Vita Enamic, VITA - EN) and nano ceramic resin composite (Lava Ultimate, 3M/ESPE - LV) blocks of 12 x 14 x 18 mm were cut into 1 mm slices. Each slice was divided into four specimens (6 x 7 mm) that were randomly allocated into 4 groups (n=8) according to the surface finishing: CTL - without surface finish (control); DB - wear with a diamond bur; VT - polishing system for hybrid ceramic (VITA); and DD - polishing system for ceramics (Dedeco). The specimens were analyzed regarding surface roughness parameters (Ra, Rz, Rq), sterilized and subjected to bacterial adhesion. Representative specimens from each group were observed by SEM and Confocal Laser Scanning Microscopy. Data were submitted to two-way ANOVA and…

Este estudo teve o propósito de avaliar métodos de manutenção da esterilidade do órgão dental humano extraído armazenado. Foram utilizados 72 dentes incisivos humanos extraídos, obtidos em clínicas de graduação e de pós-graduação da Universidade Positivo, Curitiba, PR, Brasil. Os elementos dentários foram cedidos pelos pacientes, por meio de termo de doação devidamente assinado. Após os procedimentos de limpeza e de desinfecção, 36 dentes foram esterilizados em autoclave e 36 foram somente limpos. Os dentes foram, então, armazenados em recipientes contendo o método (autoclavagem ou limpeza) ou a solução de escolha, por um período de 15 e 120 dias. Testes microbiológicos foram realizados a fim de determinar qual método ou solução de armazenamento promove a manutenção da esterilidade no tempo d...

The amount of saliva concentration and presence of cariogenic bacteria will favor the development of caries. Because of this, the aim of this study was to collect and analyze data on oral alterations referred to tooth decay, oral pH changes, and changes of the oral microbiota in two distinct groups of workers. Material and methods: 30 individuals belonging to two different groups of workers: group A (GA) – workers who maintain daily contact with the confectionery; group B (GB) – workers who do not have such contact. Saliva collection was done by analysis of the salivary pH in both groups, as well as cultivation of Lactobacillus spp and S. mutans. We also evaluate the dental status of individuals belonging to the two groups through the DMFT index. Results: After the examinations of 30 workers (17...

The aim of this study was to assess the in vitro antibacterial activity of the concentrated crude extract (CCE) and ethyl acetate fraction (EAF) of this plant against Enterococcus faecalis and compare it with calcium hydroxide [Ca(OH) 2 ] paste and 2% chlorhexidine digluconate (CHX). Methods: The plant material was collected, and an extract was prepared according to the requirements of the study (CCE and EAF). The minimum inhibitory concentrations (MICs) of CCE, EAF, Ca(OH) 2 , Ca(OH) 2 + CCE, and CHX against E. faecalis were determined using the broth microdilution method Results: The EAF inhibited E. faecalis at concentrations of 166.50, 83.25, and 41.62 mg mL −1 , and 1.00, 0.50, and 0.25% of CHX solutions showed antimicrobial activity. The MICs of Ca(OH) 2 paste were 166.50 and 83.25 mg mL −1 , whereas Ca(OH) 2 + CCE showed antimicrobial activity only at a concentration of 166.50 mg mL −1. CCE showed no inhibitory effect at any of the concentrations tested Conclusions: The CCE did not show any antimicrobial activity against E. faecalis; however, the EAF was the most effective among the three highest concentrations tested.

The debris maintenance within the sulcus prevents the effective sterilization and may compromise the disinfection of root canal systems in endodontic therapy. However, there is neither a method nor technique that standardized the cleaning of these instruments. Objective: To evaluate the cleaning ability of four techniques used in dentistry. Material and methods: For this purpose, 30 new size #40 Flexofile were used for the preparation of the canals of mandibular molars of pigs. After instrumentation, the contamination and the presence of debris in the sulcus was confirmed and the files were randomly divided into four groups: control group (without cleaning), group 1 (enzymatic detergent + manual brushing with nylon bristle brush), group 2 (ultrasound + enzymatic detergent), group 3 (ultrasound + water) and group 4 (gauze embedded in 70% alcohol). Next, all files were photographed and photographs were printed at high quality. The spirals containing debris were counted. Results: Manual cleaning with enzymatic detergent and nylon bristle brush, ultrasound with either water or detergent showed
