1 NEW YORK CITY COLLEGE OF TECHNOLOGY THE CITY UNIVERSITY OF NEW YORK DEPARTMENT OF RESTORATIVE DENTISTRY DEPARTMENT: COURSE CODE: COURSE TITLE: CONTACT INFORMATION: COURSE DESCRIPTION: CLASS HOURS & CREDITS: NUMBER OF WEEKS: CURRICULUM LEVEL: PREREQUISITES: TEXTBOOKS: Restorative Dentistry RESD 1107 Prof. Norman Russell INTRODUCTION TO NON-METALLIC DENTAL MATERIALS Prof. Norman Russell Office Hours Room P- 409 TBD Phone (718) Fax (718) This course introduces the student to the procedures of infection control and proper safety precautions in the Dental Laboratory. It will also introduce the student to non-metallic dental materials they will be using in the dental laboratory. The inherent characteristics, uses, and limitations of dental laboratory materials will be demonstrated and the student will practice the proper techniques of manipulating the materials in uncomplicated exercises. This ground work in familiarization with dental materials will facilitate the development of psychomotor skills in subsequent dental technology courses. 2 lecture hours per week; 2 credits 15 Weeks First Semester CUNY Certification in reading, writing and math or permission of chairperson.

As a community of intellectual and professional workers, the College recognizes its responsibility for providing instruction in information literacy and academic integrity, offering models of good practice, and responding vigilantly and appropriately to infractions of academic integrity. Accordingly, academic dishonesty is prohibited in The City University of New York and at New York City College of Technology and is punishable by penalties, including failing grades, suspension, and expulsion. The complete text of the College policy on Academic Integrity may be found in the college catalog. Academic dishonesty is prohibited in the City University of New York and is punishable by penalties, including failing grades, suspension and expulsion. Cheating is the unauthorized use or attempted use of material, information, notes, study aids, devices or communication during an academic exercise. Copying from another student during an examination or allowing another to copy your work. Cheating will not be tolerated during quizzes or exams, communication with anyone other than the instructor will be considered cheating. If you have a question during an examination quietly raise your hand and the instructor will come to your desk. There may be more than one version of an examination; the questions of the examinations will be the same but in different order. Students are responsible for completing their own laboratory projects, allowing others to complete your laboratory project is not permitted. Each student should clearly identify all work.
