Instruction and practice using the extension cone paralleling radiographic technique including patient management, radiation safety, use of equipment, film placement, exposure, identification and mounting, and correction of technical error. (20 hours lab/clinic. Quarter 4.).

DS 200. Practice Management I. 1 Unit.

Introduces students to the study of fundamental concepts and terminology of the art and science of practice management as a basis for leadership and decisions in dental practice. Students will learn to track and evaluate key practice indicators, read financial reports, understand the importance of leading a team for efficient delivery of patient care, track and control overhead expenses, and set goals. (10 hours. Quarter 5.).

DS 201. Integrated Clinical Sciences II: Application of Foundational Knowledge. 6 Units.

This course continues the horizontal and vertical integration of content within the ICS strand and across other clinical disciplines. Seminars include assignments tailored to prepare students to treat patients with a wide variety of conditions including medical and developmental disabilties, psychological problems, and phobias. (Quarters 5-6.).

DS 202. Integrated Clinical Sciences II: Application of Foundational Knowledge. 4 Units.

This course builds on foundational clinical and biomedical material presented in first-year studies and in DS 201 through a multidisciplinary approach to basic science principles and clinical application. Topics will be presented in a lecture format as well as smaller seminar sessions, many of which are focused on case scenarios. There is also independent study time to prepare for these activities. Emphasis is placed on the integration of dental concepts, evidence, and critical thinking to deliver accurate diagnoses, prepare customized treatment plans and consider the need for inter-professional collaboration in the delivery of oral health care. Topics include advanced endodontic content, orofacial pain, ethics, patient management, community oral health and various clinical topics. (Quarter 7.).

DS 203. Integrated Clinical Sciences II: Application of Foundational Knowledge. 3 or 4 Units.

This course continues the multidisciplinary and active learning approach used in DS 201 and DS 202. Topics include advanced content in oral surgery and sedation, endodontics, regenerative dentistry, orofacial pain, ethics, and the management of complex cases. Students are also introduced to resume and professional electronic portfolio development as they ready themselves for professional careers. (Quarter 8).

DS 211. Ethics and Professionalism Interactive Seminar. 1 Unit.

The goal of this curriculum time is to provide students the opportunity to analyze, discuss, and manage real life ethical challenges. Students will learn a systematic approach to these dilemmas applying foundational ethical and professional principles presented in their first year of dental school. Students will be assessed as follows: cases will be assigned ahead of seminar time - students must turn in a written structured report of the assigned cases for which points will be assigned. Attendance at the seminars is mandatory (roll will be taken). Students will be called on during seminar to discuss their critical analysis and justify their management decisions with the class. Student participation and involvement will be an element of assessment as well.

DS 217. Clinical Oral Diagnosis and Treatment Planning. 3-4 Units.

The diagnosis and communication to the patient of the need for dental treatment; recognizing medical, oral, physical, emotional, and economic factors that modify or complicate dental treatment; and development of comprehensive dental treatment plans suitable for patients' needs in accordance with identified modifying and complicating factors. (Quarters 5-8).

DS 266. Clinical Dental Radiology. 2 Units.

Study of preparation, evaluation, and interpretation of diagnostically acceptable intraoral radiographic and panographic surveys for comprehensive care and emergency clinic patients. (Quarters 5-8.).

DS 300. Practice Management II. 3 Units.

Challenges students to apply knowledge of practice management concepts through utilization of a computerized business simulation. Includes preparation for career decisions in dentistry with a focus on practice transitions, associateships, dental benefit plan participation, marketing, debt management, retirement planning, patient billing and collections, scheduling for efficiency, basic accounting, tax planning, and development of business plans.
