Question 10

Describe the end of a Periotomes

Answer 10

Sharp

Question 11

Describe how to use a Periotomes

Answer 11

1. Insert blade path the long axis of the tooth
2. Tip of the peristome should be located within the crest of the alveolar bone
3. Push instrument deeper into PDL space
4. Wait 10-20 secs in situ to allow for bone expansion
5. Gently push the Periotome down the PDL towards the apex

Size

Angle

How do we use luxators

Answer 13

1. Insert towards root surface to the apex
2. Apply axial pressure as you work down the root surface
3. Gently rock to sever the PDL- this creates space to create an ai gap
