Student Learning Outcomes

  • The student will create their e-portfolio and submit a project on infection control as documentation of their competency in infection control procedures.
  • The student will explain the ethical obligations to maintain the standards of dental care adhering to infection control protocols that are consistent with current federal, state, and local laws and guidelines.

Description

The first in a three course series in dental hygiene theory and practice. Focus on the principles of assessment techniques as the first phase of the dental hygiene process of care. The rationale for collection of assessment data, and associated clinical procedures will be discussed. Analysis of current evidence based literature related to the dental hygiene patient assessment procedures. 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. Analyze the steps and considerations when preforming a medical/dental history interview.
B. Identify specific conditions that may indicate the need for a physician consultation.
C. Document the gross structures of the head, neck, and oral cavity and the normal range of clinical appearance for each.
D. Explain the procedure for the extra/intraoral examination including the normal range of clinical appearance for these structures and common abnormalities that may be associated with them.
E. Describe the five categories to be included in the description of an atypical extra/intraoral lesion and the appropriate term from the glossary of extra/intraoral lesions to describe an atypical finding.
F. Describe the roles of bacterial biofilm plaque, other soft deposits, and calculus in relation to dental health and disease.
G. Identify components of the hard tissue examination.
H. Explain the factors that are assessed to determine the level of caries risk.
I. Cite the signs and symptoms of periodontitis and assessment data gathered to determine periodontal status.
J. Examine potential sources of infection and the necessity for standard blood and body fluid precautions using current evidence based research.
K. Evaluate and apply the principles of law and ethics related to assessment procedures in dental hygiene practice.
