“…However, when combined with a final rinse with CHX, the whole approach was significantly effective. A variation in PUI with the irrigant being pumped under a high flow rate through a needle attached to an ultrasonic handpiece has been proposed (19,33) and shown to improve cleaning (19) and disinfection (33,34). The antibacterial effects of the PUI approach with constant irrigation remain to be evaluated in oval-shaped canals.…”

“…Bhardwaj et al [34] reported that passive ultrasonic irrigation with1% sodium hypochlorite was effective to completely remove E. faecalis biofilms compared to natural substances (Aloe Vera, Nona juice and propolis). Whereas, Harrison et al [35] showed that 1% sodium hypochlorite with passive ultrasonic irrigation was effective, but not completely removed E. faecalis from infected radicular canals. Our results also showed that the irrigant solutions (30% red propolis alcoholic extract, 40% green propolis alcoholic extract and 2.5% sodium hypochlorite) and the irrigation protocols (conventional and passive ultrasonic irrigation) were not able to kill E. faecallis in infected root canals.…”

OBJECTIVE: This study investigated the antibacterial action of 30% red propolis, 40% green propolis and 2.5% sodium hypochlorite with irrigation protocols in infected root canals. METHODS: During 60 days, twenty-four root canals were inoculated with E. faecalis. In all experimental groups were performed root canal preparation and two irrigation protocols -passive ultrasonic irrigation and conventional irrigation. In the groups 1, 3, 5 and 7 it were made root canal preparation associated to conventional irrigation with 30% propolis, 40% propolis, 2.5% sodium hypochlorite and distilled water, respectively. In groups 2, 4, 6 and 8 it was made root canal preparation associated with passive ultrasonic irrigation with the solutions described above. The groups 9 and 10 were the controls (negative and positive). Samples of the root canals were collected and immersed in 7 mL of BHI, for 48 hours, at 37ºC. Bacterial growth was analyzed by turbidity of the culture medium. RESULTS: Antibacterial action was observed of 30% red propolis and 2.5% sodium hypochlorite when used passive ultrasonic irrigation and conventional irrigation after 20 minutes, but in 72 hours it was not effective. CONCLUSION: The irrigating agents and protocols were not effective to eliminate the microorganisms of the infected root canals. Clinical Significance: Propolis presents potential for clinical application due to its antimicrobial, anti-inflammatory, antioxidant and low toxicity properties.

MÉTODOS: Durante 60 dias, vinte e quatro canais radiculares foram inoculados com E. faecalis. Em todos os grupos experimentais foi realizado o preparo do canal radicular e dois protocolos de irrigação -irrigação ultra-sônica passiva e irrigação convencional. Nos grupos 1, 3, 5 e 7 foi feito o preparo do canal radicular associado à irrigação convencional com própolis 30%, própolis 40%, hipoclorito de sódio 2,5% e água destilada, respectivamente. Nos grupos 2, 4, 6 e 8 foi feito o preparo do canal radicular associado à irrigação ultra-sônica passiva com as soluções descritas acima. Os grupos 9 e 10 foram os controles (negativos e positivos). Amostras dos canais radiculares foram coletadas e imersas em 7 mL de BHI, durante 48 horas, a 37ºC. O crescimento bacteriano foi analisado por turvação do meio de cultura. RESULTADOS: Ação antibacteriana foi observada com própolis vermelho 30% e hipoclorito de sódio 2,5% quando utilizado irrigação ultra-sônica passiva e irrigação convencional após 20 minutos, porém, após 72 horas as substâncias não foram efetivas. CONCLUSÃO: Os agentes de irrigação e os protocolos não foram efetivos para eliminar os microorganismos dos canais radiculares infectados.

“…Por otro lado, si bien la mayoría de los estudios avalan la eficacia de este método, un único artículo de los 9 analizados afirma que la agitación con PUI resultó igual de efectiva que la jeringa convencional (15) pero, como se dijo al comentar dicho estudio, sólo se aplicó la irrigación ultrasónica durante 40 segundos, frente a los 2 minutos durante los que se irrigó con la jeringa convencional en otro grupo. A pesar de la importante efectividad de los ultrasonidos para eliminar las bacterias, algunos reivindican que la erradicación de las mismas de las paredes del conducto no es completa (11,13,14).…”

RESUMENLa eliminación de los restos de tejido pulpar vital y necrótico y de los microorganismos del sistema de conductos radiculares, es esencial para el éxito en endodoncia. La desinfección del canal radicular mediante la irrigación e instrumentación es el factor más importante en la prevención y tratamiento de la periodontitis apical. Al ser imposible con la instrumentación llegar a todas las áreas del sistema de conductos, la irrigación cobra especial importancia. Por este motivo, en la última década se han desarrollado una serie de sistemas de dispensación y agitación de irrigantes, tales como los ultrasonidos. En concreto, en este artículo de revisión se evalúa la información disponible de los diez últimos años sobre la efectividad de los sistemas ultrasónicos para eliminar bacterias, tejido pulpar, restos de dentina y barrillo dentinario, la capacidad de estos dispositivos para hacer que el irrigante penetre en el sistema de conductos radiculares y la seguridad en su uso. Los resultados de la revisión muestran que los sistemas ultrasónicos son más eficaces en el desbridamiento químico, bioló-gico y físico del sistema de conductos radiculares que los sistemas de irrigación convencional, a la vez que son seguros.Palabras clave: Ultrasonidos, irrigación ultrasónica, PUI, CUI, endodoncia. SUMMARYRemoval of vital and necrotic remnants of pulp tissues and microorganisms from the root canal system is essential for endodontic success. Disinfection of the root canal by irrigation and instrumentation are the most important factors in the prevention and treatment of apical periodontitis. As it is impossible for the instruments to reach all the areas of the root canal system, the irrigation has gained special importance. Due to this fact, technological advances during the last decade have brought new delivery and agitation devices, such as ultrasonic devices. Particularly, this review article assesses the available information from the last ten years about the effectiveness of ultrasonic devices to remove bacteria, pulp tissue, dentin debris and smear layer, and the ability of these devices to make the irrigant solution penetrate into the root canal system and the safety of its use. Nowadays scientific literature reveals that ultrasonic devices are more effective on chemical, biological and physical debridement of the root canal system than conventional technique and being safety devices at the same time.Key words: Ultrasound, ultrasonic irrigation, PUI, CUI, endodontics.

The effect of ultrasonically activated irrigation on reduction of Enterococcus faecalis in experimentally infected root canals

Abstract: Ultrasonically activated irrigation for 1 min with 1% NaOCl after canal preparation in straight root canals is potentially an effective supplementary step in microbial control.
