Pulp exposure caused by caries occur more frequent in primary than permanent teeth?! |
because primary teeth have relatively 1.large pulp chambers , 2.more prominent pulp horns and 3.thinner enamel and dentin |
|
definition of pain type of pain |
unpleasant sensation 1.somatic pain 2.psychogenic pain 3.neurogenic pain |
|
pain in sound tooth |
odontolgya D.M Hypertension sickle cell anemia leukemia |
|
favorable condition for pulp therapy |
1.Small controllable amount of bleeding 2.Small pin - point exposure surrounded by sound dentine |
|
unfavorable condition for pulp therapy |
1.Excessive uncontrollable bleeding 2.Large exposure with watery exudate or pus |
|

|
pulpotomy indication 5 contraindications 5 |
1. Deep caries , with vital pulp exposure of primary teeth 2. No history of spontaneous pain 3. Where extraction is contraindication 4. Slight amount of bleeding at exposure site 5. Normal clinical and radiographic signs 1.Radicular pulp involvement 2.Abnormal mobility 3.History of unprovoked pain 4.Presence of fistula or swelling 5.necrotic / irreversible damage pulp 6.Uncontrolled pulp hemorrhage 7.Pathological resorption of pulp |

|
Formocresol pulpotomy : It is recommended for |
primary teeth with carious exposure |
|
chemical composition Formocresol pulpotomy : |
19 % formalin , 35 % cresol in a vehicle of 15 % glycerin and distilled water . |
|
Formocresol & gluteraldehyde |
1.reversible due to week tissue fixative antimicrobial action low toxicity
2.irreversible due to strong tissue fixative bactericidal effect high toxicity root resorption |
|
There are two methods for formocresol pulpotomy : |
The one step technique ( one visit technique ) The tow steps technique ( 2 visit technique , Devitalization ) |
|
Pulp capping agents have developed along three main lines |
1- Devitalization Formocresol 19,35,15 Electro surgery Laser :
2- Preservation Glutaraldhyde 2-5% Ferric sulphate15.5%
3- Regeneration ca hydroxide 12 MTA 12.5 |
|
Formocresol another type |
Glutaraldhyde Ferric sulphate |
|
Failures following vital pulp therapy : |
1- Internal resorption : 2 - Alveolar abscess : |
|

|
histological change of place ca hydroxide |
★first day -» necrotic zone. ★after week -» fibroblasts. ★after 14 -» odontoblast. ★28 day -» reprative dentine or secondary dentine |

why we don't Place calcium hydroxide primary teeth?? |
high vascularity |
|
used for cutting cavity preparation |
rounded end high speed carbide burs no 329,330,256 245 |
|
Treatment is judged successful if there is: |
1- No sensitivity to percussion 2- No history of pain following treatment 3- No radiographic evidence of periapical pathosis or root resorption 4- No clinical evidence of pulp exposure if the tooth was re-entered |
|
Direct pulp capping is not encourage in primary teeth because |
pulp tissue ages early and less active undifferentiated mesenchyme cells less active umscs |
|
partial pulpotomy It is indicated in primary molars as it is impractical to perform complete pulpectomy in such teeth |
1.difficulty to obtain adequate access to the root canals in the small mouth of children and due to the 2.complexity in morphology of root canals having lateral branching and apical ramifications where removal of all radicular pulp content is impossible. |
|

2.low systemic toxicity.
3.short time of onset.
4.long duration of action .
5.It should not cause any permanent alternation of nerve structure |
|
composition of a local anesthesia agent |
1 - Local anesthesia 2 - Vasoconstrictor 3 - Preservative 4 - Isotonic solution 5 - Preservative 6 - Sterile water |
|
commonly used local anesthesia- |
1 ) -2 % lidocaine with 1 : 100,000 epinephrine , most commonly used 2 ) -4 % articaine with 1 : 100,000 epinephrine 3 ) -0.5 % bupivacaine with 1 : 200,000 epinephrine- long acting 4 ) -3 % mepivacaine with 1 : 20,000 levonordefrin . |
