Notes on Gutta Percha and Balata

Long-Retained Gutta Percha Pessary

The thermomechanical properties of gutta-percha. I. The compressibility of gutta-percha.

Sample wafers of compounded dental gutta-percha and uncompounded dental-grade gutta-percha were compression tested to 20,000 pounds in uniaxial and triaxial systerns. Unrestrained flow in the uniaxial series prevented development of stress levels sufficient to produce molecular compression. Negligible molecular compression did occur in the triaxial series but only above a stress level of approx...

Solvent capacity of different substances on gutta-percha and Resilon.

The aim of this study was to evaluate the effectiveness of 3 solvents (eucalyptol, orange oil, and xylol) on 2 types of gutta-percha (conventional and thermoplastic) and Resilon. Specimens (10 mm diameter x 1 mm thick; n=7 per condition) were prepared and maintained at 37 degrees C for 48 h. Each specimen was weighed on a precision scale every 24 h until its mass was stable, at which time the i...

Comparison between gutta-percha and Resilon retreatment.

Retreatment procedures in endodontic practice require complete removal of the original root filling materials. The aim of this study was to compare the amount of residual filling material on the walls of root canals that were obturated with gutta-percha or Resilon. Thirty extracted single-rooted human teeth were selected and instrumented by RaCe rotary instruments up to MAF #35. They were rando...
