Filling of root canals with adhesive materials
Journal of Endodontics, 1975A cyanoacrylate, a polycarboxylate cement, and a silicone adhesive, used in conjunction with specially devised endodontic cones fabricated of silicone rubber, were tested for their suitability as root canal filling materials. A standard endodontic technique with gutta-percha cones and zinc oxide and eugenol was used as a control.

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 ...

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.

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.

Physical properties of root canal filling materials
The Journal of the American Dental Association, 1955The process o f calcification is depend ent on the formation of a protein mat rix. This matrix serves as the ground substance within which the mineral salts are deposited. The failure to calcify in these experiments appears to be largely the result of inadequate matrix synthesis.

Sealing ability of a new root canal filling material
Journal of Endodontics, 1982Summary An in vitro study was made to test the adaptation of a new material designed to be used with the pressure syringe. The study used the dye penetration technique, gutta-percha was used as a control material. It was found that the adaptation and sealing ability of both materials were the same for 1 day, 1 week, and 3 weeks.

The chilled silver cone as a root canal filling material
Oral Surgery, Oral Medicine, Oral Pathology, 1969Abstract In an effort to improve the existing silver cone method of filling root canals, we have presented a chilled silver cone technique that relies on the malleability of silver, on silver's contraction and expansion with temperature change, and on the elasticity of dentine. A preliminary in vitro study was conducted on forty-two freshly extracted

Use of a hydrophilic plastic as a root canal filling material
Journal of Endodontics, 1976Hydron was used as a filling material in the anterior teeth of monkeys. The material showed that at periods of 103 to 348 days there was, in the majority of cases, complete healing of both vital and pulpless cases; biocompatibility with tissue; complete filling of all irregularities; and calcification of excess material in the periapical areas.
