Biocompatibility Of Root Canal Filling Materials
Australian Endodontic Journal, 2001Results of in vitro and in vivo studies clearly indicate that some endodontic sealers may cause local and systemic adverse effects. Though occasionally contradictory data has been reported from various authors, it may be concluded that zinc-oxide-eugenol sealers possess a marked cytotoxic and tissue-irritating potency.

Removal of thermafil root canal filling material
Journal of Endodontics, 1997The 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.

Impact of cross‐sectional root canal shape on filled canal volume and remaining root filling material after retreatment [PDF]
International Endodontic Journal, 2012 AbstractAimTo assess the impact of cross‐sectional root canal shape (CSRCS) on the canal volume that can be filled and the root filling material that remains following a subsequent retreatment procedure.MethodologyA total of 15 extracted two‐rooted human maxillary premolars and 15 mandibular first molars were used. Both root canals in the premolars (N =

DNA analysis of root canal-filled teeth
Legal Medicine, 2017Teeth are markedly useful as samples for DNA analysis; however, intact teeth are not always available. This study examined the possibility of identifying autosomal and Y-chromosome short tandem repeat (STR) types in samples from 34 teeth (15 intact and 19 root canal filled) that had been preserved for 10-33years after dental extraction.

The goal of root canal treatment is the healing of the inflamed apical periodontium or the prevention of inflammation. Sufficient biocompatibility of materials used in the course of treatment is considered as a prime prerequisite for an undisturbed healing, in addition to other factors such as tight sealing of the root canal.

Study on the cytotoxicity of root canal filling materials
Journal of Endodontics, 1986The purpose of this study was to evaluate the cytotoxicity in tissue cultures of six root canal sealers: Canals, Neodyne, FR, AH26, Tubli-Seal, and Nogenol. Nogenol showed mild cytotoxicity in 1-, 2-, and 3-wk test solutions at 1 and 2 days. Moderate cytotoxicity was observed in the 1- and 3-wk test solutions of Canals for all experimental days ...

[Difficulties and misunderstandings of root canal filling].
Hua xi kou qiang yi xue za zhi = Huaxi kouqiang yixue zazhi = West China journal of stomatology, 2017Root canal filling is performed as the final and most important procedure of root canal treatment. The superior 3D filling is the key determinant of endodontic success. However, such procedure remains a challenge because of the complexity of the root canal system and the limitation of root canal filling materials and methods.
