If you enjoyed Exercise 3, fill in an incisor next.


If you carved and restored all the teeth in your models, they should look something like the ones shown in Figure 2.5.

Figure 2.5: Dental models with missing teeth replaced


When you are finished, clean up and put away your materials, making sure they are in good condition. Tidy your work area.
How did you find this activity? Were you pleased with the final results of your carvings and restorations (fillings)? Do not worry if you found this task challenging! To do this type of work requires patience, meticulous attention to detail and good manual dexterity; however, in addition to strong technical ability, you must also have an artist’s aesthetic sense to produce the best results.

D ental records
This activity will give you the opportunity to examine the state of your dental health. You will do some of the work performed by dentists, dental hygienists and dental assistants. Rigour and precision are needed to complete this activity.
Using a dental record called an odontogram (a chart used by dentists to record your existing dental restorations11), you will make note of the distinctive features of your dentition.
What you will need to complete this activity:


  • Ivorine Dentoform® model

  • Odontogram




Exercise 1


Step 1
Wash your hands properly. Proper hand washing is essential to ensure the safety and well-being of your patients. To find out how to wash your hands properly, visit the POP Links website at http://liensppo.qc.ca and click on “Dentistry.” Scroll down to the “Files and Other Resources” section and click on “Hand Washing Poster.” Follow the instructions on this poster.
Step 2
Study your teeth using a disposable mouth mirror and the wall mirror.


PLEASE NOTE!
Make sure that the disposable mouth mirror you use has not been handled by anyone else. Ask your teacher for a new one if you are not sure.

To answer the following questions, use the Ivorine Dentoform® model as a reference tool. You can also visit the POP Links website at http://liensppo.qc.ca and click on “Dentistry” and then on “AllRefer.com Dental Anatomy” (in the “Websites for Activities” section). Finally, you can also consult Appendix A.




  1. Can you distinguish between your incisors, canines, premolars and molars? How many of each do you have?
















  1. Look up, down, front and back in your mouth. Do you have any silver or white fillings? If yes, identify which teeth they are on using either the names found on the AllRefer.com Dental Anatomy webpage or the numbering system shown in Appendix A.
















  1. Do you have all of your adult teeth? If not, which ones are you missing? Again, use either the names found on the AllRefer.com Dental Anatomy webpage or the numbering system shown in Appendix A.














Step 3
Using a pencil, do the following:


  • Record your restorations on the odontogram.




  • Cross out any teeth you are missing.




  • Circle any adult teeth that have not yet come through (such as wisdom teeth).


Step 4
When you are finished, throw out the disposable mouth mirror you used. Under no circumstances should it be reused by another person.
How did you find this exercise? Did you find it difficult to see inside your mouth using the mouth mirror? This is something you will practise a lot if you study to become a dentist or dental hygienist!

S elf-examination for dental plaque
You now have the opportunity to see how thoroughly you brush your teeth. This will test your powers of observation, a definite asset in dental professions.
What you will need to complete this activity:


  • Two (2) disclosing tablets

  • Paper cups

  • Disposable mouth mirror

  • Wall mirror

  • Blue and red coloured pencils

  • Two (2) odontograms

  • Dental floss, toothbrush and toothpaste (provided by student)




Exercise

First, wash your hands as you did before and then follow these steps:


Step 1
Chew a disclosing tablet and allow it to mix with your saliva. This tablet will indicate the presence of dental plaque12 on your teeth. Swish the mixture around in your mouth for 30 seconds.
Step 2
Spit out any excess liquid in a paper cup or nearby sink. Do not rinse your mouth! The disclosing tablet will stain old dental plaque blue and more recent plaque red.
Step 3
Use a disposable mouth mirror and the wall mirror in your classroom to examine the stains on your teeth. Again, make sure the disposable mouth mirror you use has not been handled by someone else. Ask your teacher for a new one if you are not sure.
Step 4
Using the blue and red coloured pencils, indicate where dental plaque appears on your teeth on an odontogram.
Step 5
Floss and brush your teeth, then redo the test. There should be less plaque this time!
For tips on how to floss and brush your teeth properly, visit the POP Links website at http://liensppo.qc.ca and click on “Dentistry.” Scroll down to the “Other Recommended Websites” section and click on “About.com Dental Care: How to Floss Properly” and “About.com Dental Care: How to Brush Teeth” in turn. (You should floss before you brush your teeth.)
Step 6
Using the blue and red coloured pencils, indicate on another odontogram the places where dental plaque still appears. You will need to work on getting rid of this plaque!
Step 7
Brush your teeth again and rinse your mouth well. Clean up and put away your materials, making sure they are in good condition. Tidy your work area.
Dentists may recommend this type of test to their patients so they can see if they are brushing their teeth effectively. Since plaque can contribute to tooth decay and gum disease, it is crucial for dentists to stress to their patients the importance of proper tooth cleaning.

I ndirect vision
To become a dental professional, you must learn how to use indirect vision, which allows you to work in a limited space like a patient’s mouth. In dentistry, indirect vision refers to “the capacity to see the treatment area [inside the mouth] by using an oral cavity mirror.”13 To simulate this experience, you will test your skills at drawing using a wall mirror.
What you will need to complete this activity:


  • Wall mirror

  • Laminated colour print of a cross-section of a tooth (if not available, use Appendix B)

  • Letter size paper

  • Red and blue coloured pencils




Exercise 1

The following activity will allow you to practise your indirect vision skills.


Step 1
Position yourself comfortably in front of the wall mirror, ensuring that you have an accessible flat surface to work on. With one hand, hold the laminated version of the cross-section of a tooth (or Appendix B) in front of you, facing the mirror. Using a piece of paper laid out on your work surface, outline the tooth cross-section by looking only at its reflection in the mirror. The resulting drawing should be a mirror image of the original image.
Step 2
Using the red coloured pencil and looking only into the mirror, trace the outline of your drawing in a clockwise direction.
Step 3
Using the blue coloured pencil and looking only into the mirror, trace the outline of your drawing again, this time in a counter-clockwise direction.
This exercise is not easy to do without cheating! Do not worry if you find it challenging. Your indirect vision skills will improve with practice.
