Workshop Plan for Digitally Recorded Lesson:

Maintaining a Chain of Asepsis in the Dental Office
Instructor: Kathryn Truant CDA
Total time:
30 min.
Workshop Outcomes: The student will identify the lifespan of pathogens on hard surfaces, apply new knowledge in a simulated clinical environment, and create a strategy for clinical application.
Prior Learning: Certified Dental Assistant or Certified Dental Assisting Student
Instructor Activities Student Activities Resources Time
Opening Strategies:LOCATION: Classroom

– Introduce topic

 – State the facts: How long infectious pathogens live on hard surfaces and how to prevent cross contamination


– Introduce relatable experience to encourage dialogue and to help learners identify with lesson

•An infectious pathogen can be transferred to a hard surface when an assistant touches an object outside of the treatment area (e.g. a drawer handle)
•An infectious pathogen (Hepatitis B) can affect a patient with a weakened immune system
•An infectious pathogen can be transferred when an assistant leaves the treatment area with treatment gloves on

 Encourage students to share prior experiences

– Listen

– Ask questions and participate in discussion

– Share prior experience if applicable

5 min.
Presentation – Lecture, Demonstration, and Practice: – Explain best practices regarding gloves

 – Solicit volunteers to participate in demonstration at the front of the class

 – Direct the remaining students to participate from their seats

 – Demonstrate the opening of a surgical tray for an aseptic dental procedure e.g. frenectomy

 – Direct participants to ‘blow the whistle’ when instructor breaks the chain of asepsis

– Make mistakes!
Examples: (SF= sterile field)
•Don’t wash hands before putting on setup gloves
•Don Mask after gloving
•Gloves on before opening tray
•Outer package of forcep or mirror touches SF
•Suture package on SF
•Lean into sterile drape
•Adjust safety glasses
•Touch computer mouse
•Open drawer with treatment gloves on

– Listen

– Volunteer

– Participate

– Pay attention to demonstration

– Indicate when instructor breaks the chain of asepsis

– whistles, party horns

– masks, gloves, safety glasses, sterile surgical tray, sterile disposables

15 min.
Post-Assessment: – Ask learners:
Can you think of items that cannot be touched with your treatment gloves?
•Outer packaging
•Lead apron, x-ray equipment
•Bare surfaces (drawer handles, cupboards, light handles, unit handles, the chair!!!)
•Personal belongings of patient
•Safety glasses
•Anything outside treatment area!

– Ask learners:
•How they will assert themselves with this information in a real setting

– Participate in discussion 5 min.
Summarize:– Summarize the importance of maintaining a chain of asepsis in the dental office

 – Encourage final questions

 – Distribute handout:

 “10 Things to Do Before Gloving” (includes a summary of the lifespan of infectious pathogens on hard surfaces, and links to applicable research)

– Listen

– Ask questions and participate in discussion

– Review handout

5 min.
