Influence of operator proficiency on the sealing ability of the vertical condensation
Journal of Endodontics, 1995This study sought to evaluate on a long-term basis the quality of the apical seal of the vertical condensation performed by three operators with different levels of proficiency in vertical compaction. Ninety anterior teeth were used. After cleaning and shaping to a size 30 file, the teeth were divided into three equal groups.

Sealing ability of five different retrograde filling materials
Journal of Endodontics, 1996The sealing ability of Amalgam, Harvard-Cement, Diaket, gold-leaf, and Ketac-Endo as retrofilling materials was investigated. Paper cones were fixed with Harvard-Cement in the instrumented roots of 100 extracted human incisors. Apicectomy was performed and a 2-mm-deep retrograde cavity was prepared.

An electrochemical study of the sealing ability of different retrofilling materials
Journal of Endodontics, 1993Eighty-eight extracted mandibular and maxillary cuspids were selected for this study. Eighty cuspids were used as experimental groups and eight were used as controls. Anatomical crowns were resected, root canals were prepared, and the apical 2 mm of the roots were removed.

Sealing ability of potential retrograde root filling materials
Dental Traumatology, 1995Abstract The sealing ability of two potential retrograde root filling materials, a light‐cured glass ionomer cement (Vitrebond) and a reinforced zinc oxide‐eugenol cement (Kalzinol) was compared with that of amalgam using three methods of assessment: bacterial leakage, confocal microscopy and Indian ink leakage.

Sealing ability of cavit and TERM as intermediate restorative materials
Journal of Endodontics, 1988The purpose of this study was to compare the ability of temporary endodontic restorative material (TERM) and Cavit to seal endodontic access cavity margins. Forty-eight extracted human teeth were divided into four groups of 12. After endodontic access, the teeth were filled with either Cavit (24 teeth) or TERM (24 teeth).

In Vitro Study of the Sealing Ability of Cements for Zirconia Restorations
Journal of Prosthodontics, 2016AbstractPurposeThe micropercolation testing of dental materials is currently used to evaluate the sealing ability. The aim of the present study is to compare the sealing ability of distinct assembling materials for zirconium oxide peripheric crowns.Materials and MethodsOne hundred teeth were prepared to be thermocycled after being distributed at random

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 ...

The sealing ability of injection-molded thermoplasticized gutta-percha
Journal of Endodontics, 1985The quality of the apical seal obtained with laterally condensed gutta-percha with sealer and injectionmolded thermoplasticized gutta-percha with and without sealer was assessed in 60 recently extracted maxillary canines. The frequency of guttapercha extension through the apex was also studied.
