DNTA 1100 - Dental Science I
Credits: 3
Catalog Description
Dental Science I covers the anatomy and physiology of the teeth, oral structures, and head and neck structures. Emphasis will be given to their anatomical parts, shape and form, clinical characteristics, development, and physiology. Dental Science I provides the student with the foundational information required to communicate effectively and perform in multicultural and diverse dental settings. This course is a prerequisite for all clinical dental assisting courses and Dental Science II.
Prerequisite(s) (must have a grade of C or better): CMST 2220 and Admission to the Dental Assisting Program
Corequisite(s): This course serves as a corequisite for the following courses:
Recommended Skills, Abilities, or Coursework: Must be able to read and write at a college level as demonstrated by meeting enrollment requirements for ENGL 1120 /ENGL 1121 .
Additional fee to student: No
