Q

Properties within formocresol?

A
  1. Tricesol - antiseptic
  2. Formalin - tissue fixative
  3. Acts by binding with bacterial and pulp tissue proteins
17
Q

Formocresol side effects?

A
  1. Carcinogenic properties
  2. If extruded via apical foramen results in damage to permanent tooth germ
18
Q

Using formocresol?

A
  1. Use small amount
  2. Blot
  3. Isolation important
  4. We’ll sealed margins to prevent leakage
19
Q

What is ferric sulphate?

A
  1. Great haemostatic agent
  2. Alternative to formocresol
  3. NOT a fixative agent
  4. Applied to pulp stump for 15 seconds
20
Q

What is Gluteraldehyde?

A
  1. Aqueous solution
  2. Fixative agent
  3. Toxic effects discovered
  4. Ineffective compared to formocresol
  5. Unlikely to be used
21
Q

What is calcium hydroxide?

A

1.Ruled out for primary teeth due to the effect of internal resorption
2. Equal efficiency with formocresol
3. No toxic side affects known

22
Q

Properties of calcium hydroxide?

A
  1. Encourages new dentine
  2. Dentine bridge is formed
  3. Pulp now has effective barrier against bacterial invasion
  4. Heals the pulp
23
Q

How to carry out pulpotomy?

A
  1. LA + isolate
  2. Outline form + remove caries
  3. Large access cavity to access pulp horns
  4. Remove entire roof of pulp chamber
  5. Remove contents with excavator
  6. Once pulp tissue exposed do not use 3 in 1 (emphysema)
  7. Irrigation
  8. Apply medicament 15 seconds
  9. Restore
24
Q

What is desensitising pulpotomy?

A

Reduces pulpal inflammation

25
Q

Desensitising pulpotomy technique?

A
  1. Open and gain access to pulp chamber
  2. Cotton pledger with ledermix directly over exposed site
  3. Place a well sealed temp dressing
  4. Review in 2 weeks
26
Q

After desensitising?

A

Extraction or pulpectomy
