Q

Why is pulpotomy prefered for developing teeth?

A

Preserve vitality, to enable apexification
This creates a more durable root and an apex that is easier to seel during obturation.

What patient information would you give to a parent of a child with an avulsed tooth over the phone?
Keep patient calm Handle tooth by crown Clean for 10 sec under cold water Try to implant the tooth and bite on tea-towel If not transport in sealed container of saliva or milk Bring to dentist within 60 minutes
43
What steps should you take for a re-implanted avulsed tooth, with a closed apex? The tooth was replanted immediately.
Leave the tooth in place Clean area with water Suture gingival lacerations Verify position of tooth Apply flexible splint Administer systemic anti-biotics
44
When should a patient be considered for a tetanus booster after replanting an avulsed tooth?
If the tooth has contacted soil, or if tetanus coverage is uncertain.
45
What steps should you take for a avulsed tooth, with a closed apex? The dry time was less than 60 minutes.
Clean tooth with saline Administer LA Re-insert tooth with gentle pressure Suture gingival lacerations Verify position of tooth Apply flexible splint Administer systemic anti-biotics

48
What are the most two common complications for a re-implanted avulsed tooth?
Ankylosis and infraposition.

50
What would a favourable outcome for a replanted tooth with an open apex be?
Asymptomatic Normal mobility Normal percussion sound Radiographic evidence of arrested or continued root formation and eruption. Pulp canal obliteration is to be expected.
51
What would a favourable outcome for a replanted tooth with an closed apex be?
Asymptomatic Normal mobility Normal percussion sound No radiographic evidence of resorption or periradicular osteitis: the lamina dura should appear normal.

54
What is the treatment for a primary tooth enamel fracture
Smooth sharp edges
55
What is the treatment for a primary enamel dentine fracture?
Seal tooth with GI to prevent microleakage. Review 3-4 weeks.
56
What is the treatment for a enamel-dentine-pulp chamber in a primary tooth?
Preserve pulp vitality with partial pulpotomy. Dress with CaOh, then restore with GI/composite. Review: - 1wk - 6-8wks - 1yr
57
What is the treatment for a crown-root fracture in a primary tooth?
If the fracture involves a small part of the root, and is suitable for restoration then remove fragment only. In all other instances extract the tooth.
58
What is the treatment for a root fracture in a primary tooth?
If the coronal fragment is not displaced, no treatment is required. If coronal fragment is displaced, then extract. Apical fragment should be left to be resorbed.
59
What treatment should be done for an alveolar fracture in a primary tooth?
Reposition the displaced segment, then place splint for four weeks. Review: - 1wk - 3-4wks - 6-8wks - 1 yr - Every year until exfoliation
60

No treatment indicated, but review 1 week and 6-8 weeks.
61
What treatment should be done for subluxation of a primary tooth?
No treatment indicated, but review 1 week and 6-8 weeks. Monitor to see if dark discoloured crown develops - if so could be a sign of infection.
62
What treatment should be done for extrusive luxation of a primary tooth?
If less than 3mm, attempt to replace the tooth carefully or leave for spontaneous realignment. Extraction if severe extrusion.
63
What treatment should be done for lateral luxation of a primary tooth?
If no occlusal interference, allow for spontaneous repositioning. If occlusal interference present, then tooth can be gently repositioned, with combined labial and palatal pressure. For severe labial displacement, extraction is indicated.
64
What treatment is indicated for intrusive luxation of a primary tooth?
If apex is displaced through bone plate, allow for spontaneous repositioning. If tooth germ compromised, then extract.
65

Do not replant, however review 1 week, 6 months, 1 year.
