Dentsply Ah plus root canal sealant

“Radio opacity
Depending on the condensation technique used, thicker layers (master point technique) down to very thin layers (lateral condensation technique) can be achieved. In order to ensure adequate visibility of the filling material even in these thin layers, the radio-opacity has further been increased in AH Plus. This was possible due to using new fillers with a greater absorption capacity.
Shrinkage, Solubility, and Expansion

The main objective of this AH Plus root canal filling is to achieve a high degree of tightness. The quality of the root canal filling directly depends on the shrinkage upon setting and the solubility of the material used, as these properties are decisive for the impermeability of the treated root canal.
Film Thickness
AH Plus has a film thickness of 26µm, which is clearly below the value of less than 50µm required by the ISO standard for root canal sealing materials.
Flow Behavior

The flow behavior of dental material is one of the most important handling properties. Firstly, favorable flow behavior results in easy mixing. Secondly, the filling material must be able to be introduced easily into the root canal and exhibit a certain stability there. Therefore, AH Plus has been designed to be slightly thixotropic. A flow of 36 mm also perfectly meets the requirements of the ISO standard (> 25 mm).
Sealing Abilities

AH Plus has an excellent ability to seal root canals and make them impermeable.
Adhesion to dentin

It gets easily adhered to the dentine and results in reducing the risk of root canal microleakage and maintaining a cohesive filling mass.”

“STEP 1

Preparation of the Root Canal
Prior to the application of AH Plus, prepare, clean, and dry the root canals to be filled using state-of-the-art endodontic techniques.
STEP 2

Dosage and Mixing
Using AH Plus in tubes: Mix equal volume units (1:1) of Paste A and Paste B on a glass slab or a mixing pad using a metal spatula.
Mix to a homogeneous consistency.”
