Sealing Ability of Dentin Adhesives/Desensitizer
Operative Dentistry, 2007Clinical Relevance Depending on the application of the individual adhesives used, dentin adhesives seal dentin surfaces and reduce dentinal permeability. Dentin adhesives possessing a high sealing ability for dentin surfaces are suggested for the treatment of dentin hypersensitivity.

Sealing Ability of a New Polydimethylsiloxane-based Root Canal Filling Material
Journal of Endodontics, 2008 We tested the null hypothesis that there is no difference in the sealing ability of GuttaFlow, RoekoSeal, and AH26 in root canals. Sixty extracted mandibular premolars were filled with AH26 (lateral compaction), RoekoSeal, or GuttaFlow (modified single ...

Sealing Ability of Three Fiber Dowel Systems
Journal of Prosthodontics, 2009Abstract Purpose: To study the sealing ability of two new fiber dowel systems. Materials and Methods: Thirty‐six extracted single‐rooted teeth were endodontically treated and randomly assigned to two new fiber dowel systems and a control group: (1) an E‐glass‐based dowel, everStick‐POST, cemented with ParaCem Universal DC resin cement (EV); (2) a glass‐

Effect of intracanal medicaments on the sealing ability of TERM
Journal of Endodontics, 1990An in vitro leakage study was performed to determine the effect of intracanal medicaments on the sealing ability of Temporary Endodontic Restorative Material (TERM). Fifty extracted mandibular molars with uniform access preparations were restored with TERM after placement of either a dry cotton pellet (control) or a pellet moistened with eugenol ...

Apical Sealing Ability Of Five Endodontic Sealers
Australian Endodontic Journal, 2001ABSTRACTBecause apical leakage may be a cause of failure of endodontic treatment, the purpose of this study was to compare the apical seal provided by five endodontic sealers. After cleaning and shaping procedures, the root canals of 75 human cuspids were obturated by lateral condensation using guttapercha and the following sealers: Kerr Pulp Canal ...

Intracoronal Sealing Ability of Two Dental Cements
Journal of Endodontics, 2002The purpose of this study was to compare the efficacy of sealing the coronal 2-mm of the root canals versus covering the entire pulpal floor with one of two dental-resin cements (Principle or C&B Metabond). Sixty-two molars with the occlusal half of the crowns and the apical half of the roots removed were used.

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.

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.

Effect of restoration thickness on the sealing ability of TERM
Journal of Endodontics, 1993An in vitro study was done using a fluid filtration device to compare microleakage of Temporary Endodontic Restorative Material (TERM) at various thicknesses. Forty-four extracted mandibular molars had their roots removed at the cementoenamel junction, occlusal table flattened, and a standardized endodontic access made in the crown.

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 ...
