This article reviews recent reports describing the aetiology of dental trauma from national and international studies as well as the different classifications currently used to report dental injuries. It also discusses possible preventive measures to reduce the increasing frequency of dental trauma. Reported studies demonstrate that males tend to experience more dental trauma in the permanent dentition than females, however, there does not appear to be a difference between the sexes in the primary dentition. Accidents within and around the home were the major sources of injury to the primary dentition, while accidents at home and school accounted for most of the injuries to the permanent dentition. The most frequent type of injury was a simple crown fracture of the maxillary central incisors in the permanent dentition while injuries to the periodontal tissues were more common in the primary dentition. When preventive measures are being planned, knowledge of aetiology is important. More prospective studies from representative populations are required to understand the complexities of dental trauma epidemiology and to allow implementation of preventive strategies to reduce the increasing frequency of dental trauma.

This article reviews empirical and theoretical studies that examined the relationship between risk perception and sexual victimization in women. Studies examining women's general perceptions of risk for sexual assault as well as their ability to identify and respond to threat in specific situations are reviewed. Theoretical discussions of the optimistic bias and cognitive-ecological models of risk recognition are discussed in order to account for findings in the literature. Implications for interventions with women as well as recommendations for future research are provided.

With the advancements of technology and its increasing use in all spheres of life, clinicians too are faced with the decision of whether to adopt or refrain from adopting certain innovations in their practice. This article discusses the process of adopting clinical innovations within a theoretical framework, namely diffusion of innovations theory (DIT; Rogers, 2003). DIT constructs are applied to the example of online therapy adoption into clinical practice. Nine adoption barriers are identified, including issues of dehumanizing the therapeutic environment, start-up cost and reimbursement, infrastructure and training, licensure and jurisdiction concerns, ethical guidelines, both client and clinician suitability factors, and professional reputation and acceptance within the field. The authors conclude with a theory-based discussion of activities that may help to accelerate the adoption of online therapy among professional psychologists.
