Homogeenid

Homogeenid is a type of plastic or polymeric endodontic obturation material used in modern root canal therapy. Invented in the 1980s, it is designed to fill the root canal system with a light-cured, biocompatible, and radiopaque material.

Homogeenid is primarily composed of BisGMA, a synthetic resin that is combined with camphorquinone, a photoinitiator, and other additives to enhance its physical and optical properties. When exposed to light, the BisGMA initiator causes the material to polymerize, or solidify, into a hardened mass that seals the root canal.

The properties of homogeenid make it an attractive alternative to traditional gutta-percha and cement root canal fillings. It is reportedly more resistant to fracture and dimensional change than older materials, and it bonds well with tooth structure. Homogeenid is also radiopaque, which allows for easier visualization and detection of any remaining obturation material on radiographs.

Homogeenid has been endorsed by many endodontists as an effective and reliable material for root canal therapy, although its long-term durability and potential for pulpal irritation have not been extensively studied. Some studies have indicated higher marginal diameters and canal transportation when using homogeenid, which may be a limitation.

Despite some potential drawbacks, homogeenid is a cutting-edge material that offers distinct benefits in root canal therapy. Its developer posits that it is capable of forming a tight, long-lasting seal in even the most challenging anatomical settings. While further studies are necessary to fully validate its efficacy and safety, homogeenid remains a valuable tool in the modern root canal arsenal.
