Evaluation of internal sealing ability of three materials
Journal of Endodontics, 1992Thirty-six maxillary central incisors were prepared in a manner similar to nonvital bleaching procedures. They were examined with respect to the degree of procion green dye penetration of dentin with and without heating. Cavit, IRM, and zinc phosphate cement were used to evaluate their sealing ability.

Postrelease dive ability in rehabilitated harbor seals
Marine Mammal Science, 2011AbstractThe efficacy of seal rehabilitation is examined in a postrelease study of dive ability in harbor seal pups (Phoca vitulina) in the Wash, United Kingdom. Six rehabilitated seals were fitted with Sea Mammal Research Unit (SMRU) Argos Satellite Relay Data Logger tags and their individual dive behavior was monitored for an average of 122 d.

Sealing ability of spherical hull transfer skirts
Journal of Marine Science and Application, 2010An improved spherical, movable transfer skirt for autonomous submersibles has been devised. It was designed to permit the transfer of equipment and personnel from a submersible to the pressure chamber of an oil storage sea-bed structure. It also allowed mating at large vertical angles while the submersible remained horizontal.

The relative sealing ability of paste-type filling materials
Journal of Endodontics, 1982The sealing ability of four types of syringeable paste filling materials was compared with laterally condensed gutta-percha with Tancredi sealer. Eight groups with ten extracted human single-rooted anterior teeth in each group were uniformly prepared and obturated with PCA Sealer, ZOE, Endo Fill, Hydron, gutta-percha with Tancredi sealer, and gutta ...

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.

Long-term sealing ability of a calcium hydroxide sealer
Journal of Endodontics, 1991A calcium hydroxide sealer (Sealapex) was compared with a zinc oxide and eugenol sealer (Tubli-Seal) over a 32-wk interval to examine solubility in an in vitro simulation. After obturation with gutta-percha and the appropriate sealer, specimens were immediately immersed in a saline solution to challenge the sealers' solubility.

Comparison of the sealing ability of four obturation techniques
Journal of Endodontics, 1990This study compared the apical seal produced by four obturation techniques. The Canal Finder system was compared with lateral condensation, the Ultrafil system, and the sectional warm gutta-percha techniques. Forty-two anterior single-rooted teeth were instrumented. Ten teeth were not obturated and served as positive and negative controls.

An evaluation of sealing ability of calcium hydroxide sealers
Oral Surgery, Oral Medicine, Oral Pathology, 1989Solid core filling material such as gutta-percha has been used to fill the root canal in conjunction with a sealer to prevent apical leakage. The purpose of this study was to compare apical seal of five different root canal sealers. Sixty roots of maxillary central incisors were cleansed and shaped and randomly assigned to one of six groups of ten ...

Bonding effectiveness and sealing ability of fiber-post bonding
Dental Materials, 2008To evaluate the push-out bond strength and the sealing ability of five adhesive cements routinely used for fiber-post bonding.Fifty extracted single-rooted teeth were randomly divided in five groups and restored using Parapost FiberLux and the following luting agents: Panavia 21 (PAN), Clearfil Esthetic Cement (CLF), Variolink II (VAR), RelyX Unicem ...

The sealing ability of injection‐moulded thermoplasticized gutta‐percha
International Endodontic Journal, 1989Summary. The root canals of 120 single rooted teeth were prepared with files and then divided randomly into twelve subgroups. Four operators each filled three of these subgroups, one group with laterally condensed gutta‐percha, one group with thermoplasticized gutta‐percha with sealer and one group with thermoplasticized gutta‐percha without sealer ...
