The information and examples in this book are designed to orient dental hygiene students to clinical practice and its many applications in an office setting. Although dentists, dental practices, and dental hygiene can be generalized, each practice will be unique in its daily operations and policies. As you read and participate in the exercises, keep in mind that experiences will be unique. In this new millennium, the art and science of dental hygiene continues to progress and evolve. More states have entered into independent or alternative practice settings for experienced dental hygienists. Upon becoming a registered or licensed dental hygienist, you are encouraged to actively participate in furthering the development of patient education and dental hygiene research as well as your own education. Reach out to communities that are not able to access dental care in a traditional setting and continually stay abreast of the link between periodontal disease and total body health, as patients see the dental hygienist as the oral health care specialist. The knowledge and relationships that build from networking with other professionals will be invaluable. We hope that you find personal and professional satisfaction in your dental hygiene career and as a member of the dental hygiene profession. Thank you to the reviewers of this manuscript: W.
