The pace of change and innovation in dentistry is high and dentists and dental care professionals must keep abreast of developments. Mandatory continuing professional development for dentists was introduced in 2000 and for dental care professionals in 2008. E-learning has become an important part of an individual's personal development portfolio as it allows dentists to study at a convenient time, while establishing a record of their continuing professional development. Dental professionals can pay to access a wealth of learning material provided by the Dental Channel both online and on CD, but despite a wide range of products and a user base of 7,000 dental professionals -- not just dentists but hygienists, therapists, nurses and technicians as well -- the Dental Channel found there was still something missing. The WebEx Training Centre combines media support for PowerPoint and other media, such as video, with the opportunity for dentists to talk to each other and to experts.
