Rootfilled

Rootfilled is an adjective used in dentistry to describe a tooth that has undergone root canal therapy, specifically when the root canal system has been cleaned, disinfected, and obturated to seal the canal space from bacterial reentry. The term denotes that the tooth has received endodontic treatment and has a filled root canal structure.

The canal space is typically filled with gutta-percha cones used with a dental sealer to achieve a hermetic seal. Some cases employ resin-based sealers, mineral trioxide aggregate for apical sealing, or carrier-based obturation systems. The goal is to prevent reinfection while providing a stable coronal base for restoration. Materials and techniques vary by case and practitioner preference.

Procedure and assessment: After access cavity preparation, the pulp is removed, canals are cleaned and shaped, irrigants such as sodium hypochlorite are used, the canals are dried, and then obturated. A subsequent restoration, often a crown, protects the tooth from fracture. Radiographs verify proper length and density of the fill and check for any overfill or voids. Long-term success depends on maintaining a good coronal seal and the overall condition of the tooth.

Prognosis and considerations: The success of a rootfilled tooth depends on canal system complexity, quality of obturation, and the integrity of the final restoration. Rootfilled teeth can function for many years but may have a fracture risk similar to other endodontically treated teeth; thus coronal coverage is commonly recommended, especially for posterior teeth.

Etymology and usage: The term stems from root (the anatomical root of the tooth) and filled (obturation). In clinical notes, a rootfilled tooth is distinguished from vital teeth and from teeth lacking proper canal sealing.
