AH Plus® Root Canal Sealing Material is a two-component paste/paste root canal sealer based on epoxy-amine resin, offering the following features: Long term sealing properties Outstanding dimensional stability Self-adhesive properties To be used with hot or cold technique. AH Plus® achieves a tight seal due to its self-adhesive properties and dimensional stability. It is biocompatible and exhibits moderate anti-microbial properties and therefore has the potential to significantly reduce the germ load in the canal. It is extremely radio-opaque so it is clearly visible on radiographs. AH Plus® is a good sealer choice for use with ProTaper Thermafil® obturators as the setting reaction is not adversely affected by thermoplastic obturation.
