The investigation of thermal behaviour and physical properties of several types of contemporary gutta-percha points.

Chemical compositions and initial phase changing temperature by DSC varied according to the various brands of gutta-percha points. Conform Fit TM gutta-percha had the lowest percentage of inorganic fraction and thermal conductivity amongst these six brands of gutta-percha. Thermal conductivity had the strongest positive correlation with the percentage of inorganic components and zinc, whilst there was a negative correlation to the amount (ratio) of gutta-percha.
