Periodontal therapy offers an excellent opportunity for the dental team to deliver patient care (Fig. 42.1). All members of the team need to be clear about their roles within the team and good communication is required so that health messages and practice policies are consistent (Figs. 42.2, 42.3). Additional training, duties that can be undertaken, and the registration of qualifications continue to change with time and differ across the world.
