RESUMO
Introduction: the aim of this study is to determine the current trends of irrigation during root canal therapy by specialists who are members of the Chilean Endodontic Society. materials and method: a survey (survey monkey -SurveyMonkey.com) was e-mailed to the 485 members of the Chilean Endodontic Society. the instrument was translated and adapted from the survey "irrigation trends among American Association of Endodontists members: a web-based survey" applied in the USA in 2012. participants answered a set of 16 questions that included irrigant selection, irrigant concentration, the adopted protocol, techniques or devices for irrigant activation. results: 99 percent of respondents use sodium hypochlorite as the main irrigant. data indicate that 74 percent of respondents use hypochlorite at a concentration of 5 percent. most respondents (94 percent) also include EDTA in their usual practice. In addition, 90 percent of respondents reported that they activate the irrigating agent, and 94 percent confirmed that they perform a final irrigation protocol. conclusion: the majority of respondents use sodium hypochlorite as the main irrigant at a concentration of 5 percent, use ethylenediaminetetraacetic acid (EDTA) as a smear removal agent, activate the irrigant, and perform a final irrigation protocol.

El Síndrome de Waardenburg representa la forma más común de sordera congénita; es una condición pleitrópica, autosómica dominante, con penetrancia y expresividad variable. Se describen dos casos clínicos de Síndrome de Waardenburg tipo II. Las principales manifestaciones son la sordera sensorioneural congénita, alteraciones de la pigmentación pilosa y cutánea, puente nasal ancho, hipertricosis de las cejas, mandíbula cuadrada, encanecimiento prematuro y alteraciones neurológicas. Se revisan los criterios de diagnóstico de la enfermedad y los hallazgos asociados descritos de la literatura
