Madarati AA, Qualtrough AJE, Watts DC. Endodontists experience using ultrasonics for removal of intra‐canal fractured instruments. International Endodontic Journal 43 , 301–305, 2010. Abstract Aim To investigate the experience of UK endodontists with aspects of ultrasonic use for removal of intra‐canal fractured instruments. Methodology A questionnaire form comprising both close‐ended and partially close‐ended questions with a covering letter explaining the aims of the study and indicating that all information would remain confidential and anonymous were sent to 180 endodontists working in the UK. Non respondents received a reminder with a differently worded covering letter. After collecting the responses, data were entered into SPSS software through which frequencies were determined and the chi‐square test at the 0.05 level of significance, when required, was applied. Results Overall, 97% of endodontists reported the use of ultrasonics for removal of fractured instruments. The majority of them (78%) used ultrasonics with a coolant at least some of the time. Forty‐seven per cent of users activated tips at medium to maximum power settings. The greatest proportion (53%) activated the tips for approximately 10 s. Conclusions Endodontists reported different techniques when using ultrasonics for removal of fractured instruments.
