Endodontic Therapy Flashcards
What is the definition of Indirect Pulp Cap?
- Single stage caries removal to hard dentine
- Biomaterial placement over thin layer of remaining dentine
What is the definition of Selective Carious Tissue Removal
- Selective caries removal to soft or firm dentine on pulpal wall
- Biomaterial placement on pulpal wall of cavity
What is the definition of Stepwise Excavation
- First stage removal of caries to soft dentine on pulpal wall and
temporisation - 6-12mths later caries removal to firm dentine, biomaterial & permanent
restoration
What is the definition of Direct Pulp Cap
- Class I: no pre-operative deep caries i.e. pulpal exposure due to trauma or
iatrogenic damage - Class II: Carious exposure, disinfectant and calcium silicate cement used
What is the definition of Partial Pulpotomy
- Removal of a small portion of coronal pulp
- Placement of biomaterial and restoration
What is the definition of Full pulpotomy
- Removal of all coronal pulp
- Placement of biomaterial and restoration
Name the 3 essential aspects for all vital pulp therapy?
- Magnification
- Aseptic technique
- Peripheral seal caries free to enable
peripheral seal
Describe the recommended treatment for pulpitis?
Vital pulp treatment or Root canal treatment
Restoration to function
Supportive postoperative care
Describe the recommended treatment for non-traumatic pulpitis with no pain or non-spontaneous pain
Selective/stepwise caries removal without pulp exposure.
If pulpal exposure direct pulp capping or pulpotomy (partial
or full)
Describe the recommneded treatment for apical periodontitis?
Root canal treatment
Restoration to function
Supportive postoperative care
Describe the recommneded treatment for emergency management of pulpitis or apical periodontitis
Vital Pulp Treatment or Root Canal Treatment
Describe the recommneded treatment for pulp necrosis +/- AP with immature permanent tooth?
Apical plug technique or revitalisation
How does CaOH, MTA and biodentine differe over post-treatment survival?
MTA performed significantly better than CaOH at all time points
No significant difference between MTA and biodentine however no
darkening with biodentine
How does pulpal bleeding infleunce the outcome of pulp therapy success?
Therefore, ensure haemostasis prior to pulp caping and ensure no
space for bleeding below cap
If not possible to cease bleeding progress from pulp capping →
partial pulpotomy → full pulpotomy → pulpectomy (i.e. RCT)
What aspect of RCT technique have the strongest evudebce for improving outcome for AP?
NiTi rotary > hand SS (weak)
NaOCl then EDTA, then NaOCl (open)
No need for intracanal medication if single visit is possible (strong)
Obturation with GP, cold lateral, with ZOE sealer (open)
No need for adjuncative therapy (weak)
