Resumen
Objetivo: Comparar la efectividad del hipoclorito de sodio al 5,25% sólo y activado ultrasónicamente, para remover el dressing de hidróxido de calcio de conductos laterales simulados.Materiales y métodos: Se realizó un estudio experimental in vitro con 24 dientes humanos uniradiculares recién extraídos, a los que se les realizaron conductos laterales simulados; fueron instrumentados y obturados con un dressing de hidróxido de calcio y almacenados por siete días a 37ºC en 100% de humedad. Los dientes se asignaron mediante una aleatorización por bloques para ser irrigados con NaOCl al 5,25% (grupo 0) y con NaOCl al 5,25% activado ultrasónicamente (grupo 1). Se usó la misma técnica para obturar ambos grupos. Se tomó radiografía y se evaluó cada diente, identificando el número de conductos simulados obturados. Para el plan de análisis se consideró aplicar el test de chi2, test de rangos de Wilcoxon o prueba t según la naturaleza y la distribución de las variables.Resultados: No se encontraron diferencias estadísticamente significativas entre los dos procedimientos.Conclusiones: El hipoclorito de sodio al 5,25% sólo o activado con ultrasonido remueve igual el dressing de hidróxido de calcio de conductos laterales simulados de diámetro pequeño.[Gómez PA, Ojeda CA, Rincón ML. Efectividad de la limpieza ultrasónica de conductos laterales simulados posterior a la utilización de un dressing de hidróxido de calcio. Ustasalud Odontología 2006; 5: 9 - 14]
Purpose: To compare the effectiveness of sodium hypochlorite 5,25% alone and ultrasonically activated on the calcium hydroxide dressing elimination from simulated lateral canals.Material and methods: An experimental, in vitro study with 24 recently extracted single root human teeth were created simulate lateral canals and instrumented to the working length, each tooth was filled with a calcium hydroxide paste and incubated at 37ºC, 100% humidity for seven days. Teeth were randomly divided in to groups, in group 0 the dressing was removed using sodium hypochlorite irrigation and master file, and group 1 the dressing was removed using sodium hypochlorite irrigation and a # 15 activated U file during one minute. Both groups were obturated using termomechanical compaction. Postoperative radiographs were taken and evaluated; data were analyzed statistically using Mann Whitney or T student and chi square test.Results: No statistically significant differences were found between both groups 0 and 1.Conclusions: The sodium hypochlorite 5.25% alone or activated with ultrasound don’t remove completely dressing of hydroxide of calcium of simulated lateral canals of small diameter.
