Student Learning Outcomes

  • The student will assess anatomical features of the teeth and apply appropriate advanced instrumetation techniques for effective root surface debridement.
  • The student will evaluate gingival health and assimilate soft tissue curettage into dental hygiene treatment plan. (This will be evaluated with a written exam.)


Discussion and demonstration of advanced and supplemental dental hygiene functions: digital intraoral photography, dental hygiene instrumentation, ultrasonic scaling techniques, soft tissue curettage and locally delivered antimicrobials. Supportive course to reinforce and amplify the knowledge and skills needed to perform dental hygiene procedures in the clinical setting for D H 320B. 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. Integrate the technique of digital intraoral imaging into dental hygiene practice.
B. Assess patient oral conditions and determine appropriate instruments for effective advanced dental hygiene instrumentation.
C. Demonstrate appropriate advanced ultrasonic techniques for dental hygiene treatment based on individualized patient needs.
D. Evaluate patient periodontal status and administer locally delivered antimicrobials when appropriate.
E. Analyze gingival health and integrate soft tissue curettage into dental hygiene treatment as needed.
F. Discuss procedures and post-operative instructions with patients.
G. Adhere to standard infection and hazard control protocols during all procedures.
H. Apply the principles of law and ethics to the practice of dental hygiene.
