COURSE DESCRIPTION:

This course covers the concept of dental practice clinical chairside assisting.  Emphasis will be place on chairside assisting in dental restorative procedures, coronal polishing skills, fluoride treatment application, and hands-on manipulation of dental materials will be preformed in a preclinical, clinical and/or laboratory situation.  Student learning will center on enhancing the students’ procedure anticipation, dexterity and skills of chairside assisting, and dental laboratory procedures.

5.

COURSE GOAL:

In a clinic or laboratory setting, using all safety procedures, the cognitive of dental materials will be applied during the manipulations of impression materials, gypsum products, restorative materials, acrylic resins and dental waxes.  Emphasis will be placed on using manufacturer's instruction and specifications.  Some proficiency tasks and/or clinical observations must be performed and completed within set clinical/laboratory dates.

This course carries two credits for a total of 45 contact hours.

6.

EVALUATION PROCEDURES:

40%

The student’s grade will be based on the scores received on unit tests. 30% is applied to quizzes, unit tests, and the final examination and 10% is applied to worksheets and assignments.

20%

Will be based on student’s attendance and tardiness (3 pts per session = 45 pts. per semester), clinic team rotation participation (5 pts per session = 75 pts per semester), and professional behavior/ work ethic (See Student Handbook - ex. respectable, team player, responsible patient care, dependable, etc.).  3 tardy equate to 1 absence.

40%

The student's grade will be based on scores received by the student on skills performed based on the rating scale value of the Proficiency Task sheets in a preclinical, clinical and dental laboratory setting.
