Dentsply Sirona's AH Plus Jet® automix syringe for conventient intra oral application
Dentsply Sirona's AH Plus®, introduced in 1995 in EU, is the most researched endodontic sealer in the world(1). In more than 800 million root canal fillings, it has proven itself to be effective and is now considered the benchmark for newer product developments but still remains the “Gold Standard”. To celebrate its 30th anniversary, Dentsply Sirona is publishing an updated, comprehensive scientific manual featuring selected clinical studies. These clearly validate the clinical evidence of the effectiveness and reliability of AH Plus® and demonstrate its consistent performance in various treatment scenarios.
Charlotte. Endodontic sealers are essential as part of the final step in endodontic treatment: obturation, in which it is important to seal the canal permanently and effectively to prevent reinfection. AH Plus® from Dentsply Sirona has a proven 30-year track record and is now the world's most extensively researched brand of endodontic sealers.
Chemically stable for a long-term, reliable sealing
This success was preceded by extensive product development, led by Prof. Joachim E. Klee in his former role in the R&D department at Dentsply Sirona. Klee describes the unique technology behind AH Plus® as follows: “The material is based on linear epoxy-amine addition polymers, these ensure a certain degree of flexibility. In addition, it has high adhesion to dentin and gutta-percha(2), extremely low solubility and outstanding dimensional stability(3). This enables long-term, reliable sealing.”
Studies provide clinical evidence
Over the years, AH Plus® endodontic sealer has become a “Gold Standard” in obturation in the scientific literature thanks to its properties. This is supported by an extensive study evaluation in the scientific manual published by Dentsply Sirona to celebrate the 30th anniversary of AH Plus®. The selected and peer-reviewed clinical studies were published between 2007 and 2024 and cover a total of 3,407 patients and 3,735 treated teeth. One of the key findings: High treatment success rates were observed with the use of AH Plus® regardless of the obturation technique (including single cone obturation) and type of treatment (primary or secondary).
Beth Ann Damas, DDS, MS, from Orland Park (IL), is convinced of the qualities of the product: “AH Plus sealer is my go-to and has been since residency. It is consistent and reliable. I have had a lot of success with this product. I can recommend AH Plus to my colleagues: Time tested, proven by research, consistent and reliable.”
AH Plus® is one of Dentsply Sirona's top brands within its endodontics portfolio and offers instruments and workflows for all aspects of endodontic treatment: “We know that dentists want to have a sealer that delivers reliability and durability over the long term,” explains Arjan de Roy, Group Vice President Essential Dental Solutions at Dentsply Sirona. “We are convinced that our updated, comprehensive scientific manual will help boost trust in AH Plus® and give dentists the confidence they need to deliver successful endodontic treatments.”
