At the conclusion of this course, the student should be able to:
1. Identify the physical, mechanical, chemical and biological properties of dental materials and their biocompatibility with the oral tissues.
2. Perform selective coronal polish procedures for the removal of stains and soft deposits.
3. Identify the components of polishing and abrasives in dentistry and distinguish between finishing, polishing, and cleansing.
4. Describe the advantages and disadvantages of the different impression materials and demonstrate the clinical technique on taking alginate impressions.
5. Describe the physical properties important to model and die materials and demonstrate proper pouring and separation of a cast using gypsum material.
6. Describe the uses, properties, and manipulation of direct metal and esthetic restorative materials, and identify their components including composites, and dental amalgam, advantages and disadvantages.
7. Compare the ingredients of in-office and home whitening agents and indicate the type of dental stains for which whitening techniques may be effective.
8. Demonstrate the method of whitening tray fabrication including patient instructions.
9. Describe the clinical success of sealants, list the steps involved, and demonstrate application of sealants on student partner.
10. Identify the uses of cements in dentistry for medication, bases, luting agents, restorative agents, and build-up.
11. Describe the difference between metals, alloys, and ceramics used in dentistry today, and how they differ in composition, physical properties, optical properties, and clinical applications.
12. Identify materials used in dental implants, as well as types, and the use of digital imaging technology.
13. Identify components and materials used for fixed and removable restorations and orthodontic appliances including polymers and indications for their use.
14. Discuss the science behind partial caries removal and minimal invasive dentistry as it relates to the placement of interim therapeutic restorations.
