pathways of the pulp - 10th edition 625~630

Vital pulp therapy: Requirements for Success

• Treatment of a noninflammed pulp

• Bacteria-tight seal

• Pulp dressing

MTA as a capping agent• high pH similar to calcium hydroxide when unset

• after setting, will create an excellent bacteria-tight seal

• hard enough to act as a base for a final restoration

• need a moist environment for at least 6 hours to set properly—> two step procedure

• cause discoloration in the tooth crown

• high cost

partial pulpotomy technique• anesthesia,possibly without a vasoconstrictor

• rubber dam

• superficial disinfection

• 1-to 2-mm deep cavity into the pulp using a high-speed hand piece with a sterile diamond bur

• If bleeding is excessive, the pulp is amputated deeper until only moderate hemorrhage is seen

• excess blood is carefully removed by rinsing with sterile saline and the area is dried with a sterile cotton pellet

• 5% NaOCl is recommended to rinse the plural wound

• chemical amputation of the blood coagulum

• remove damaged pulp cells, dentin chips, and other debris

• provide hemorrhage control with minimal damage the normal pulp tissue underneath

• do not allow blood clot to develop

partial pulpotomy technique

• 1-to 2-mm deep cavity into the pulp

• using a high-speed hand piece with a sterile diamond bur

• until only moderate hemorrhage is seen

• excess blood is carefully removed

• 5% NaOCl

• do not allow blood clot

• little or no history of pain

• absence of radiographic signs, percussion sensitivity, swelling, or mobility

• exposures exceeding 2mm, bleeding could not controlled within 1~2minutes excluded

• 93.5%, 91.4% healing

Partial pulpotomy on asymptomatic young permanent posterior teeth(calcium hydroxide)

pulpotomy on symptomatic young permanent (calcium hydroxide)

• 6 teeth

pulpotomy on symptomatic young permanent teeth(calcium hydroxide)

• 26 permanent vital molars with caries pulp exposures and apical periodontitis

• 16~ 72 months observed

• 24 teeth (92.3%)

methods

• 40 patients (7~45 years)

• pulp-capping treatment

• no more than reversible pulpits (cold test, radiographic examination)

first visit

• remove caries using a caries detector

• hemostasis using NaOCl

• place Pro-root MTA over the exposures and all surrounding dentin

• restore provisionally with un-bonded Clearfil Photocore

second visit

• sensibility test

• confirm MTA curing

• restore with bonded composite

results

• observation period: 9 years

• followed : 49/53 teeth

• favorable outcome: 97.96%

• all teeth having open apexes showed completed root formation(15/15)

• Odontogenicity

• Sealing effect

• Anti-bacterial effect

Our results indicate that ProRoot and Endocem have similar biocompatibility and odontogenic effects. Therefore, Endocem is as effective a pulp capping material as ProRoot. (J Endod

conclusion

• decrease the risk of endodontic treatment

• shorten chair time of removing infected dentin

• safer material in deciduous teeth pulpotomy than FC

• reduce treatment expenses

• improve treated tooth’s prognosis

discussion

• long-term follow-up

• need to examine cytotoxity and calcinogenicity over longer duration

• need to study treating inflamed pulp tissue
