“…In this way, an adequate fluidity is necessary to facilitate penetration and draining of the radicular canal (24). Yamazaki et al (25) studied dentin permeability and efficiency of Endo-PTC (which is utilized as a lubricant in endodontic instrumentation) in semi-solid pharmaceutical forms with different excipients as hydroxyethylcellulose or carbomer polymeric gels and associations of polyethylene glycol and surfactants. The results did not show differences between the evaluated preparations in terms of penetration capacity into dentin tubules or efficiency.…”

This study aimed to synthetize, characterize and evaluate the antimicrobial properties of silver nanoparticles to be used in the development of a root intracanal formulation. Silver nanoparticles (AgNPs) were obtained by reduction of silver nitrate with sodium borohydride and characterized by UV-Visible spectrophotometry, scanning electron microscopy (SEM) and dynamic light scattering (DLS). The antimicrobial activity of nanoparticle formulation was evaluated by determinations of the minimum inhibitory concentration (MIC) and minimal bactericidal concentration (MBC) against different bacterial species by the microdilution method, according to recommendations of the Clinical and Laboratory Standards Institute (CLSI). Three potential vehicles, hydroxyethylcellulose, Carbomer and polyethylene glycol were tested as carriers for formulations containing AgNPs. The efficiency of the synthesis method chosen to produce AgNPs was demonstrated by four characterization techniques. The nanoparticles showed antibacterial activity against all species tested. Incorporation of AgNPs into all experimental vehicles produced stable formulations but the one in hydroxyethylcellulose presented better physical proprieties. The results indicate that silver nanoparticles are potential antiseptic agents to be used in root canals and incorporation in adequate vehicles may favor a broader application.

Purpose: To evaluate the bond strength of a total-etching adhesive system to dentin irrigated with 1% sodium hypochlorite (NaOCl) and ethylenediaminetetraacetic acid 17% (EDTA).Methods: Thirty human molars were sectioned 3mm below the oclusal surface and were randomly divided into 3 groups (n=10): G1, no treatment (control); G2, 1% NaOCl; G3, NaOCl followed by EDTA. The specimens received the total-etching adhesive system, restored with microhybrid composite resin, sectioned and trimmed to create 4 hourglass-shaped slabs of each tooth. The slabs were tested in microtensile bond strength in a universal testing machine (Emic DL 2000) at a crosshead speed of 0.5 mm/min until fracture. The results were analyzed statistically by ANOVA and Newman-Keuls test. G2 samples were not submitted to the test because they fractured just before testing, and its values were considered zero to the statistical analysis.Results: The means and standard deviations (MPa) were: G1, 8.41 (±3.51); G2, 0.0 (±0.00); G3, 8.47 (±3.53).Conclusion: It was concluded that the application of the NaOCl irrigating solution significantly decreased the bond strength values. The use of NaOCl followed by EDTA resulted in bond strength values not statistically different from control group.Key words: Adhesives; dentin; root canal irrigants ResumoObjetivo: Avaliar a resistência de união de um sistema adesivo condicione-e-lave à dentina irrigada com hipoclorito de sódio 1% (NaOCl) e ácido etilenodiaminotetracético 17% (EDTA).Metodologia: Trinta molares humanos foram seccionados 3mm abaixo da superficie oclusal e aleatoriamente divididos em 3 grupos (n=10): G1 (controle), nenhum tratamento; G2, NaOCl; G3, NaOCl seguido por EDTA. Os especimes foram hibridizados com um sistema adesivo condicione-e-lave, foram restaurados com resino composta microhibrida e seccionados de forma a originar 4 amplulhetas de cada dente. As fatias foram submetidas ao teste de resistência de união à microtraçnao em máquina universal de ensaios (EMIC DL 2000) à uma velocidade de 0,5 mm/min até o momento da fratura. Os resultados foram analisados estatisticamente por ANOVA seguido por Newman-Keuls. As amostras do G2 não foram submetidas aos testes de resistência de união pois fraturaram antes dos testes, e seus valores foram considerados zero para análise estatística.Resultados: A média e desvios-padrão foram (MPa): G1 -8,41 (±3,51); G2 -0,0 (±0,00); e G3 -8,47 (±3,53).Conclusão: Pode-se concluir que a irrigação com NaOCl diminui significativamente os valores de resistência de união. O uso de NaOCl seguido por EDTA resultaram em valores de resistência de união sem diferença estatística com o grupo controle.
