Journal ArticleDOI
The thermomechanical properties of gutta-percha. 3. Determination of phase transition temperatures for gutta-percha.
TL;DR: Thesis (M.Sc.D.)--Boston University School of Graduate Dentistry, Dept. of Endodontics, 1973.
Journal ArticleDOI
The thermomechanical properties of gutta-percha: II. The history and molecular chemistry of gutta-percha
TL;DR: The various early uses of gutta-percha are reviewed, its molecular chemistry is discussed, and its molecular Chemistry is discussed.
Journal ArticleDOI
The thermomechanical properties of gutta-percha. Part V. Volume changes in bulk gutta-percha as a function of temperature and its relationship to molecular phase tranformation
TL;DR: If the gutta-percha in the apical segment is not elevated above 45 degrees C, molecular transformation is avoided and the ultimate volume changes which accompany temperature cycling are small, predictable, and controllable.
Journal ArticleDOI
The thermomechanical properties of gutta-percha. Part IV. A thermal profile of the warm gutta-percha packing procedure.
TL;DR: A thermal profile of the warm gutta-percha technique was produced by the thermocouple instrumentation of natural teeth and the subsequent monitoring of intraradicular temperature changes during the packing procedure, which produced consistent, representative temperature ranges.
Journal ArticleDOI
The thermomechanical properties of gutta-percha: I. The compressibility of gutta-percha
TL;DR: Compressibility values for compounded dental gutta-percha proved to be less than that of water, considered for all practical purposes to be incompressible, and no molecular “spring-back” can be expected to assist in the seal at the dentin-gutta- percha interface.
