The aim of the study is to find the rotary instrument usage and preferred brand of rotary instrument among endodontists working in dental colleges, Chennai. A rotary instrument is used to remove or reduce tooth matter and to shape teeth during endodontic procedure. Rotary instrument includes burs and endodontic files. Various brands of rotary instruments are currently available in the market which includes dentsply protaper, Mtwo, endostar, k3 XF files, Heroshaper etc. The choice of rotary instrument by a dentist is governed by various factors like their efficiency, ductility, sharpness, cross section and flexibility. An online questionnaire based study was conducted among 97 endodontists working in dental colleges in Chennai. A total of 10 questions consisting of both open ended and close ended questions related to usage, preferred brand and properties were included in the questionnaire . Datas were collected from the filled questionnaire and analysed. Descriptive statistics was used. From the study it was reported that 88% of endodontists use rotary instruments for endodontic procedures in their clinical practice. The most preferred brand of rotary instrument used by endodontists is Mtwo (40%) because of its good cutting ability and shaping followed by 20% k3, 18% protaper, 6% heroshaper and 36% combination of different rotary instruments. Majority of the endodontists preferred using rotary instruments and nearly half of them opt to use mtwo file in their clinical practice.

Security Concerns

A password is considered to be the first line of defence in protecting online accounts, but there are problems when people handle their own passwords, for example, password reuse and difficult to memorize. Password managers appear to be a promising solution to help people handle their passwords. However, there is low adoption of password managers, even though they are widely available, and there are fewer studies on users of password managers. Therefore, the issues that cause people not to use password managers must be investigated and, more generally, what users think about them and the user interfaces of password managers. In this paper, we report three studies that we conducted: on user interfaces and the functions of three password managers; a usability test and an interview study; and an online questionnaire study about users and non-users of password managers, which also compares experts and non-experts regarding their use (or non-use) of password managers. Our findings show that usability is not a major problem, rather lack of trust and transparency are the main reasons for the low adoption of password managers. Users of password managers have trust and security concerns, while there are a few issues with the user interfaces and functions of password managers.

The Impact

PurposeGrowing evidence supports the role of student assistantships in enhancing graduates’ preparedness for practice. However, there is limited evidence concerning the impact of aligning assistantships with graduates’ first doctor post. The aims of our study were to determine newly-qualified doctors’ views on the value their assistantship experience, effects on anxiety levels, confidence and preparedness for increased responsibilities, exploring change over time and whether effects differ according to assistantship alignment.DesignWe conducted a longitudinal cross-sectional online questionnaire study examining experiences of aligned and non-aligned assistantships across the transition from medical student to newly-qualified doctor. The questionnaire was distributed to final year medical students within Wales, UK (n=351) and those commencing their first post in Wales, UK (n=150) in June 2015 at Time 1 (T1), and repeated in September 2015 (1 month following transition, T2) and January 2016 (T3).ResultsResponse rates at T1 were 50% (n=251, aligned=139, non-aligned=112), T2 36% (n=179, aligned=83, non-aligned=96) and T3 28% (n=141, aligned=69, non-aligned=72): 15% (n=73, aligned=36, non-aligned=37) completed all questionnaires. Paired longitudinal analysis was undertaken where possible. Significant differences were observed between participants on aligned and non-aligned assistantships in terms of the value they place on their assistantship experiences, their anxiety, confidence levels and preparedness for responsibility.ConclusionAlthough not sustained, aligned assistantships seem to provide graduates with additional benefits during the August transition. Further work is required to establish what it is about the aligned assistantship programme that works and why.

Background Clinical instructors (CIs) are important to the provision of real-world experiential learning because they teach, mentor, and support students in clinical practice settings in higher education programs. CIs experience tensions that influence their retention and impact the sustainability of consistent, quality education for students. Purpose The aim of this study was to examine the experiences of being a CI and how to better support them. Methods CIs in a nursing faculty at a Western Canadian university were approached to participate. Data collection included a survey ( n = 17) with questions asking about the importance of and their ability to prepare, teach, and mentor nursing students in practice. Individual interviews ( n = 6) and a focus group ( n = 3) were conducted that asked CIs about their experiences and challenges. Analysis included descriptive statistics and thematic analysis. Results Participants indicated feeling unprepared entering the instructor role. Key findings were the need to improve CI orientation so that it is more practical and meaningful, to increase peer support from other instructors, and to assist CIs’ transition into becoming educators. Conclusions Understanding CIs’ assessment of their needs can help institutions better support and retain them, promoting consistency and quality in practicum instruction.

Rotary Instrument

The frequency of separation of NiTi rotary instruments has increased with the increasing use of these instruments, and this error may result from inadequate experience of using these instruments. This iatrogenic error can complicate root canal treatment, and special experience is required to manage this problem. This case report describes the management of the separation of an F3 instrument from a ProTaper NiTi rotary system. A 30-year-old man was referred to the College of Dentistry, Taibah University (Saudi Arabia) with an intracanal separated NiTi rotary instrument (F3 of the ProTaper system; Dentsply Maillefer, Ballaigues, Switzerland) in the canal of the maxillary right canine. The separated instrument was removed by using the modified hollow tube–based extractor system. The present case revealed that sometimes a simple method can be an effective alternative of a professional method; using NiTi rotary instruments with strict adherence is important for the prevention of instrument separation.
