Unique in content and approach, this text is devoted entirely to case situations that provide opportunities for problem-based learning in multiple dental hygiene sciences at any point along the learning continuum—from beginning to advanced. The text's 10 diverse case-based learning scenarios help students learn to apply basic knowledge to client care, develop critical thinking skills, and link their classroom learning to real-world experiences they may encounter in clinical practice. Case study work will also prepare them for success on national, regional and state examinations which have a client care focus. Each chapter contains one complete case scenario with accompanying questions categorized both by difficulty (basic or complex) and by dental hygiene discipline—making it a complete module that may be introduced or revisited in any order and at any time during the curriculum.
