Intended for students in the Dental Hygiene Baccalaureate Degree Program; enrollment is limited to students accepted in the program.

Course Objectives

The student will be able to:
A. Describe the elements of a extraoral and intraoral exam or oral cancer screening.
B. Compare and contrast the clinical presentation of five different lesions that have vesicular appearance.
C. Compare and contrast the clinical presentation of five different ulcerative lesions.
D. Discuss the similarities and differences between ecchymoses, petechiae, and purpura in the red and purple lesions.
E. Identify the etiology, method of transmission, and pathogenesis of white lesions in the oral cavity.
F. Describe three factors that contribute to the pigmentation of the oral tissues.
G. Discuss the characteristics of the human papillomaviruses (HPV) and differentiate between the the high risk and low risk types.
H. Identify the different types of processes associated with the development of soft tissue enlargements.
I. Describe the three clinical signs that may be associated with each of the following hard tissue lesions: osteosarcoma, chondrosarcoma, and Ewing sarcoma.
J. Describe several ways a dental hygienist or dentist can be instrumental in determining the origins of skins lesions and discuss why that is important.
