Dr. med. dent. Sebastian Zorn

Your specialist for Endodontology


Regular root canal treatments are performed by almost every general dentist. A meta analysis done by a leading german university unfortunately showed a success rate of less than 50% in these cases.
The success rate is directly connected to the ability of the dentist to clean all areas inside of an infected tooth. Cleaning these tiny, sometimes smaller than 0.1mm, root canals is almost impossible if you cannot localize them. The human eye is usually not able to detect all infected areas inside of a tooth, that’s why the operating microscope plays a crucial role in modern root canal treatment.
In the last decades some groundbreaking inventions like the operating microscope, special nickel-titanium instruments, electronic lenght measuring, ultrasonic irrigation, and special biocompatible filling cements enabled much better outcomes than before.
Modern endodontics should be performed by an endodontic specialist using all these inventions to increase the success rate up 85% to more than 90%.

„You can’t treat what you can’t see“

Following the quote of my mentor Prof. Syngcuk Kim, one of the founders of microscopic endodontics, the access to the root canals perfectly illuminated and magnified is the key to a successful treatment.
Only in a setting like this you can find all hidden canals and treat them successfully. In magnification you can also remove previously fractured instruments, repair iatrogenic perforations of the root or detect micro-cracks of the tooth.
To achieve the best results every time we are using top of the notch ZEISS dental microscopes in every root canal treatment.

To get high success rates in root canal treatment the major aim is to create a bacteria free situation.
Because of that it is crucial to perform all treatments under a so called rubber dam or dental dam. That simple trick enables the secure isolation of the treated tooth from the bacteria in the patients mouth. Sometimes, if the defect of the tooth does not allow the placement of a dental dam a stable composite build up should be placed on the tooth at first. That build up also secures the root canals between the appointments from reinfection and the tooth at all from fracture.
Some studies showed, even after regular sterilization process, that used intruments can still contain bacterial priones.
Because of that we only work with single-use nickel-titanium intruments to avoid the transfer of bacteria from one patient to the other.

During the last years, our root canal specialist Dr. Sebastian Zorn, exclusively performed root canal treatments and microscopic root end surgery with a magnification up to 30x.
After years of attending national and international continuing education programs he successfully took part of the „International program in endodontics and endodontic microsurgery“ at the Ivy league University of Pennsylvania/USA from 2011 to 2013.

With high technical effort and a lot of experience and passion we are nowadays able to successfully treat even „hopeless“ teeth, to keep them for very long periods of time.

According to ESE (European Society of Endodontology) guidelines all root canal treatments in our office are performed with rubber dam, under dental microscopes, electronic lenght measuring and ultrasonic/sonic driven rinsing protocol. The filling of the root canals is either performed in warm vertical compacted Guttapercha technique or with biocompatible cement like MTA (MineralTrioxidAggregat).
If needed glassfiber posts are placed right after the root filling.

Following procedures are performed:

  • root canal treatments on teeth with complex anatomy
  • retreatments of previously treated teeth
  • removal of posts and fracured instruments
  • repair of iatrogenic perforations
  • retreatment of teeth after apicoectomy
  • treatment after dental trauma (revascularisation therapy)
  • microscopic root end surgery
  • intentional replantation

Dr. Sebastian Zorn also works on a referrer base. Patients who are referred to our office for special treatments are only treated on the mandate and will be sent to the general dentist after performed therapy. The referrer will be informed about the whole procedure and will be supported in decision making, if needed.
