Course Description

This preclinical course includes a theoretical and practical component. The theoretical

component is designed to give the third year students basic cognitive knowledge of theprincipals, terminology, instruments, materials and techniques utilized in the practice of

Operative Dentistry. The practical component provides the student with the initial

experience in the application of restorative procedures for managing the carious process

on phantom heads. The student should perform a series of clinical exercises utilizingcurrent instrumentation, materials, and techniques.
