Studies on the Root Canal Filling Method

Physical properties of root canal filling materials.

Root canal filling materials, including sealercement and obturation points or cones, are used in root canal treatment to occlude the apical portion of the canal. These will block the dentinal tubules preventing passage of tissue fluids, toxins, and microorganisms into the root canal space. Many investigators have demonstrated the importance of a sealer cement for effective root canal obturation...

Removal of Thermafil root canal filling material.

The aim of this study was to evaluate if removal of Thermafil plastic carriers and reestablishment of working length were possible in single rooted teeth filled with the Thermafil system. Twenty freshly extracted maxillary central incisors were prepared and filled with #30 Thermafil plastic obturators according to manufacturer's recommendations. Teeth were divided in two groups: Group I: 10 tee...

Filling root canal systems: the Calamus 3-D obturation technique.

Periapical repair after root canal filling with different root canal sealers.

The aim of this study was to evaluate periapical repair after root canal filling with different endodontic sealers. Sixty-four root canals from dog s teeth were filled, divided into 4 groups (n=16). Root canals were instrumented with K-type files and irrigated with 1% sodium hypochlorite solution. Root canals were filled in the same session by active lateral condensation of the cones and sealer...

Rationale and efficacy of root canal medicaments and root filling materials with emphasis on treatment outcome

There is overwhelming evidence that endodontic diseases can be characterized as infectious diseases. There is no longer any question that microorganisms are at the center of the etiological causes of pulpal and periradicular pathological processes (1, 2). There are many secondary reasons contributing to tissue breakdown and endodontic failures, such as root perforations, instrument fractures, e...
