Maintain original arch length Prevent premature loss of primary teeth Prevent abnormal habits |
|
|
Options for pulp treatment in vital teeth?
|
Indirect pulp capping
Direct pulp capping (for permanent teeth) Pulpotomy |
|
|
Options for pulp treatment in non vital teeth?
|
- Pulpectomy
– Extraction |
|
|
Indirect pulp capping indications?
|
Deep carious lesion close to the pulp
Clnically and radiographically healthy pulp |
|
|
What are the steps for indirect pulp capping?
|
pre op radio
LA, rubber dam Remove most caries except that's closest to the pulp Place a thin layer of CaOH Place IRM, GIC and CR Review every 6 to 12 months for 2,3 years |
|
|
Direct pulp capping indications?
|
Small mechanical pinpoint pulp exposure
Asymptomatic tooth |
|
|
T/F
Direct pulp capping is indicated for a pin point exposure of the pulp due to caries |
False
Exposure due to caries is not recommended |
|
|
Steps for Direct pulp capping
|
Pre op radio
LA, rubber dam Removal of caries Wash, dry exposure point by sterile pellet CaOH, IRM, CR Review every 1-12 months for 2-3 years |
|
|
Direct pulp capping is NOT recommended on primary teeth
T/F? |
True
|
|
|
Indications for Pulpotomy?
|
Loss of marginal ridge
Asymtomatic Pulp reversably and minimally inflammed (confined to coronal pulp) Absecne of abcess No inter-radicular, apical pathology No evidence of internal resorption |
|
|
Contra indications of pulpotomy
|
Internal/external pathological resorption
Periapical and inter-radicular radiolucency Signs of acute dental infection Pulp calcification Uncontrollable haemorrhage from amputated pulp Unrestorable tooth |
|
|
What to look out for before doing pulpotomy in a radiograph?
|
Depth of caries
Furcation involvement Bone resorption Internal/external root resorption Calcified body in the pulp |
|
|
What are pulpotomy medicaments?
|
Formocresol
Ferric sulphate (15.5%) MTA |
|
|
Steps for Formocresol/ferric sulphate pulpotomy technique
|
Preop radio
LA with rubber dam Remove caries and determine site of pulp exposure Remove roof of pulp chamber Remove corornal pulp Apply formocresol with cotton pellet for 5 mins Remove cotton pellet and check haemorrhage has stopped Fill pulp chamber with ZOE Restore tooth using SSC Post op radio |
|
|
Pulpectomy indications?
|
Irreversible inflammation extending to the radicular pulp
Chronic pain Swelling, absecss, fistula, sinus tract Necrotic pulp Furcation/apical radiolucency |
|
|
Pulpectomy contraindications?
|
unrestorable crown
advanced pathological root resorption less than 2/3 root length left |
|
|
Steps of pulpectomy technique?
|
LA
Rubber dam Remove caries, determine site of pulp exposure Remove roof of pulp chamber Remove coronoal pulp to identify canal orifices Take radiograph with the files in canals Estimate the working length from the radiograph 1-2mm Remove radicular pulp tissue upto WL Debride using K File (size 15 to 30) (Typical RCT) Temporise with IRM, Obturate with ZOE, metapex, Fill pulp chamber with IRM/GIC Finish with SSC Post op radio |
