Ultradent UltraCal XS # 5117-1 is a radiopaque, premixed calcium hydroxide paste with a high pH of 12.0 to 12.5, designed for direct application in dental procedures. It comes in a 1.2 ml delivery syringe with a recommended 29 ga NaviTip™ Single Sideport tip for precise flow control, making it ideal for root resorption, pulp capping, apexification, and perforations in both primary and permanent teeth. This gluten-free paste elevates dentin pH to alkaline levels, but caution is advised to avoid extrusion into sensitive anatomical areas, and proper protective gear must be worn during application. The stepwise instructions ensure safe and effective usage, with guidelines for storage, disposal, and maintaining compliance with regulations.

Indications



direction to use 

Preparation:

  • Complete root canal instrumentation to the necessary apical enlargement.
  • Clean and dry the canal.
  • Irrigate the canal with sterile water to remove any debris.
  • Verify the working length using an apex locator.

Application:

  • Remove the Luer Lock cap from the UltraCal XS paste syringe.
  • Attach the recommended 29 ga NaviTip™ Single Sideport tip to the syringe.
  • Verify the flow consistency before intraoral expression.
  • Slowly dispense UltraCal XS paste into the canal, evaluating the rate of expression.

For Temporary Dressing, Apexification, Perforation Management, and Vital Pulp Therapy:

  • Ensure the rubber stopper on the NaviTip is 3–4 mm shy of the apex.
  • Gently and carefully deliver UltraCal XS paste into the canal without forcing it beyond the apex.
  • Take an X-ray to verify proper placement.
  • Remove excess paste from the pulp chamber and seal the coronal opening.

Monitoring and Follow-Up:

  • Leave UltraCal XS paste in the canal for 1–3 weeks.
  • Monitor closely and repeat application as necessary.
  • For apexification, change paste every 4 weeks and avoid treatment beyond 6 months.

Removal:

  • After the desired period, remove UltraCal XS paste using Citric Acid 20% with NaviTip™ FX™ Tip.
  • Rinse the area with sterile water and dry the canal.
  • Proceed with the final canal obturation using the preferred sealing system.

For Non-Vital Primary Dentition:

  • Follow similar steps but ensure the rubber stopper is shy of the apex and use extra care due to varying canal lengths.
  • Apply a thin layer of Ultra-Blend™ plus calcium hydroxide liner after paste application.

Post-Application:

  • Process the syringe with an intermediate-level disinfectant between uses.
  • Store and dispose of waste according to local regulations.
