dc.description.abstractSince its introduction into dentistry last year, there have been only a few articles published about Hydron[R], the root canal filling material, and none specifically related to the composition and physical characteristics of the material. The purpose of this study was to investigate the general composition of Hydron[R] and to investigate some basic properties of Hydron[R] which are related to the permanent success of a root canal filling material. The investigative methods included data derived from infrared spectroscopy, high performance liquid chromatography, linear and volumetric measurements, and water-soluble dye solutions. From the experimental methods in the study most of the basic components of Hydron[R] were identified and some physical characteristics were described. In attempting to correlate clinical observations from the experimental results, it appears that the polymeration of Hydron[R] in a moist environment like a root canal system could affect the final physical structure of the gel and also result in more residual impurities which could leach out of the hydrogel. Lastly, it appears that the final apical extent of Hydron[R] from the root canal would be difficult to manage since controlling the polymer during injection is not easy and controlling the amount of extension of polymer outside the terminus of the root canal during swelling is not easy.en_US
