Dental technician John Sjöding founded Sendoline in 1917. Having initially concentrated on manufacturing dental gold alloys and dental laboratory products, he soon realized the need to extend the scope of the operations to include endodontic products.
Since 2005 Sendoline AB is a part of the Austrian W & H Group.

Sendoline develops, markets and sells root canal files, as well as motors for mechanical cleaning of root canals for dental care.
The head office is located in Arninge / Täby, in the region of Stockholm, involving 10 employees. Sendoline’s market is international and the company has sales units in Scandinavia, England, France and the Middle East.

  • In 1980 the S-file® was introduced. The cylindrical core design of the S-file® provides perfect flexibility and excellent debris transportation. In addition, the double cutting edges provide an even greater cutting ability than the traditional H- or K-files.
  • In 1990 Sendoline launched its first Nickel Titanium files along with the NiTi-TEE® Rotary file system, used for mechanical cleaning. The unique features of this material are flexibility, safety and durability – major innovations for both dentists and patients.
  • The S5 concept including the cordless S5 Endo Motor and S5 Rotary Files was launched in 2007 facilitating endodontics with its five preset torque settings. From 2016 the S5 Endo Motor is provided with an apex clip for easy connection to an apex locator.
  • In 2016 Sendoline decided to switch the labelling from re-usable to single-use root with the purpose to ensure safer, time saving and more efficient root canal treatments.
  • In the same year Sendoline’s first pre-sterilized root canal instruments were put on the market: The S5 Rotary Files STERILE, K-File STERILE followed by the unique S1 concept including pre-sterilized S1 Files for reciprocating use with the S1 contra-angle handpiece with integrated gearbox for connection directly to the dental unit.
  • The latest achievement of Sendoline are the pre-sterilized S1 Plus instruments launched in December 2017 providing further elasticity and flexibility to the reciprocating S1 concept.
