Comparison of conventional root canal obturation techniques with thermafil obturators

Journal of Endodontics, 1992
This study compared microleakage of Thermafil Obturators to the single cone technique in Lexan blocks simulating root canals (n = 20) stained with Prussian blue dye. The microleakage of Thermafil and laterally condensed extracted human teeth was also investigated after the teeth were stained with India ink or Prussian blue dye over 1- or 2-wk dye ...

‘Simultaneous technique’ and a hybrid microseal/pacmac obturation

Dental Update, 2011
In these endodontic case reports we present a root canal preparation protocol using the Mtwo Ni-Ti rotary files according to the ‘simultaneous technique’ which is a ‘crown-down’ approach, where every instrument in the sequence is used to the full working length. A hybrid Microseal/PacMac obturation (consisting of three stages: master cone compaction,

Comparison of the sealing ability of four obturation techniques

Journal of Endodontics, 1990
This 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.

Technique for quick conversion of an obturator into a hollow bulb

The Journal of Prosthetic Dentistry, 2001
SUMMARY A technique for the quick fabrication of a hollowobturator bulb for patients with maxillary resectionhas been described. The prosthesis is simple to con-struct, lightweight, and easy to clean; it has no directjunction between the oral, nasal, or antral environ-ments and the interior of the obturator.

Root strains associated with different obturation techniques

Journal of Endodontics, 1995
The influence of different obturation techniques (lateral condensation, Obtura, and Thermafil) on root strains was assessed in 27 upper central incisors using strain gauges mounted on the coronal and apical one-thirds of the root surface. The vertical load applied with each obturation technique was also measured. Comparison of the strains was conducted

Apical sealing efficacy of endodontic obturation techniques

International Endodontic Journal, 1986
Summary. This study in vitro utilized methylene blue dye to evaluate root canal apical leakage after maxillary central incisors were serially instrumented and obturated with laterally condensed guta‐percha and sealer, a single fitted gutta‐percha master cone and sealer, sealer alone or paste alone.

A technique for fabrication of polydimethylsiloxane-acrylic resin obturators

The Journal of Prosthetic Dentistry, 1983
A flexible silicone obturator is an alternative to the acrylic resin obturator. It can be useful for patients with severe trismus who cannot insert a large prosthesis, as the flexibility of the hollow silicone section allows easy placement and removal (Fig. 9).

Comparison of the obturation of lateral canals by six techniques

Journal of Endodontics, 1999
The following obturation techniques were compared on their ability to obturate lateral canals in vitro, lateral condensation (LC), continuous wave of condensation (CW), warm vertical condensation (WV), carrier-based thermoplasticized gutta-percha (CB), warm lateral condensation (WL), and vertically condensed high-temperature gutta-percha (HT).
