AH Plus®

AH Plus® builds on decades of clinical success with over 800 million root canal fillings performed with the AH Plus product family*. The sealer provides excellent long-term sealing,1 outstanding adhesion to gutta-percha2 and exceptional radiopacity3 and is designed for cold and warm obturation techniques4— especially in single-cone workflows. 

Why choose AH Plus?

Improved consistency & adhesion

Next generation of AH Plus with improved paste consistency and improved adhesion to gutta-percha support overall success of root canal treatment.2

Excellent long-term sealing

Significantly lower short-term and long-term leakage profiles compared to evaluated bioceramic sealers.1

Exceptional radiopacity

Easy identification of the sealer on radiographs. The radiopacity of AH Plus (next gen) is first-rate compared to other resin and bioceramic sealers.3

Designed for all obturation techniques

Ideal for cold and warm techniques—especially for single-cone obturation thanks to favorable dimensional stability by slight expansion.4

Combine the performance of AH Plus  (next gen)

AH Temp™ combines high pH level with easy handling

Effective disinfection of root canal with AH Temp, a highly alkaline paste with a pH level of 12 based on calcium hydroxide that allows direct and precise application into the root canal.

  • Reduced desiccation (less blocking of cannulas during application and of syringes over time as well as less waste of desiccated syringes)
  • Excellent radiopacity enables reliable x-ray control5
AH Plus Cleaner for the removal of excess unset AH Plus (next gen)

AH Plus Cleaner is a proprietary mixture designed to effectively remove mixed amines and epoxy pastes from natural tooth surface.

  • Allows for immediate direct restorative procedure after the root canal obturation with AH Plus (next gen)

Enhanced endodontic sealing performance

Excellent long-term sealing properties 

AH Plus (next gen) provides excellent long-term sealing properties. Low leakage values indicate tight sealing and provide evidence of high-quality obturation performance.1

Significantly lower short-term and long-term leakage profiles compared to evaluated bioceramic sealers.1
Adhesion to gutta-percha

Outstanding adhesion to gutta-percha compared to bioceramic root canal sealers.2 This promotes the seal’s integrity and reduces the risk of leakage, supporting the overall success of the root canal treatment.
Exceptional radiopacity

Easy identification of the sealer on radiographs. The radiopacity of AH Plus (next gen) is first-rate compared to other resin and bioceramic sealers.3
Designed for all techniques — excellent for single-cone obturation

With its favorable dimensional stability by slight expansion,4 AH Plus (next gen) is an excellent choice for any technique, especially single-cone obturation.

How to

Step 1:

Remove the cap by turning it 90° counter-clockwise and pulling it.

Step 2:

To ensure an appropriate mixing ratio, dispense a small amount of paste from the syringe prior to the first clinical application.

Step 3:

Attach the mixing tip to the syringe, aligning the notch. Then turn the tip 90° clock-wise.

Step 4:

The intraoral tip can be rotated and the angle adjusted.

Step 5:

For intraoral use, it is recommended to cover AH Plus Mixing Syringe with the Disposa-Shield® Sleeve.

Step 6:

The sealer can be applied directly to the root canal orifices or extruded conventionally on a mixing pad.

Step 7:

After the sealer application, mixing tip and intraoral tip must be discarded. Replace the cap on the syringe head.
