While dental hygiene and dental assisting students learn oral radiographic theory in the classroom, it is through laboratory practice that students perfect the skills necessary to assume professional roles. This laboratory manual challenges students to link theory with clinical practice. Designed to complement Essentials of Dental Radiography for Dental Assistants and Hygienists, 10th Edition, Exercises in Oral Radiography Techniques: A Laboratory Manual serves as a workbook to guide a student in the practice of radiographic techniques with ready-made exercises, which include mounting diagrams to attach finished radiographs and pages that allow a student to turn in assignments for instructor evaluation. Each of the student-centered activities requires minimal preparation by an instructor, and explicit directions guide independent, self-paced practice. Providing students with guided exercises that facilitate the development of dental radiographic skills, while providing instructors of oral radiology with a resource for meaningful laboratory activities, continues to be the goal of the fourth edition of Exercises in Oral Radiography Techniques: A Laboratory Manual. A thorough revision, in combination with a reorganization of topic presentation, reflects the educational recommendations of dental hygiene and dental assisting curriculum guidelines.
