The field of dentistry lacks satisfactory tools to help visualize planned procedures and their potential results to patients. Dentists struggle to provide an effective image in their patient's mind of the end results of the planned treatment only through verbal explanations. Thus, verbal explanations alone often cannot adequately help the patients make a treatment decision. Inadequate attempts are frequently made by dentists to sketch the procedure for the patient in an effort to depict the treatment. These attempts however require an artistic ability not all dentists have. Real case photographs are sometimes of help in explaining and illustrating treatments. However, particularly in implant cases, real case photographs are often ineffective and inadequate. The purpose of this study is to develop a mobile application with an effective user interface design to support the dentist–patient interaction by providing the patient with illustrative descriptions of the procedures and the end result. Sketching, paper prototyping, and wire framing were carried out with the actual user's participation. Hard and soft dental tissues were modeled using three dimensional (3D) modeling programs and real cases. The application enhances the presentation to the patients of potential implants and implant supported prosthetic treatments with rich 3D illustrative content. The application was evaluated in terms of perceived ease of use and perceived usefulness through an online survey. The application helps improve the information sharing behavior of dentists to enhance the patients' right to make informed decisions. The paper clearly demonstrates the relevance of interactive communication technologies for dentist–patient communication.

Passwords still remain a very common authentication method for online accounts. Many studies have investigated people's risky password management behaviour, including reusing passwords, writing them down, and sharing them with others. However, most studies provide limited information about the demographics of their participants. There may be substantial differences in password management behaviour between younger and older people, as they represent very different generations with different experiences of the Internet, and investigation of these differences could be a first step to helping people manage their passwords more appropriately. An online survey asked 45 younger and 47 older people about their password management behaviour. Significant generational differences were found in password behaviours including storing passwords, sharing them with others, forgetting them, and logging in from a shared computer. There were also significant differences in respondents' ratings of their password security knowledge and password strength. Finally, there was a significant social desirability bias in answers to several questions.

Passwords remain the most common form of authentication in the digital world. People have increasing numbers of passwords, and research suggests that many people undertake risky password management behaviours such as reusing passwords, writing them down and sharing them with friends and colleagues. It is not clear whether people persist in these behaviours because they do not understand the risks involved or the benefits of the behavior outweigh the risk. An online survey was undertaken with 120 MTurk workers in which they rated the risks, benefits and likelihood of undertaking 15 password management behaviours. They also completed the Marlow-Crowne Social Desirability Scale to investigate whether their responses, particularly of the likelihood ratings, were affected by social desirability. An interesting pattern of responses was found with some groups of behaviours more affected by perceptions of the benefits and others equally affected by the perceptions of the risks and the benefits. These results have implications for how information about risky password behaviours in presented to users and general education about password security.
