gutta-percha baseplate
1.a whitish rubber derived from the coagulated milky latex of the gutta-percha tree.
2.Group 1: filled with zinc oxide-eugenol sealer and gutta-percha (ZOE) (the control group);
5.The effect of different fungi on the decomposition of cellulose in the leaves of Eucommla ulmoides were studied to select suitable ones for the extraction of gutta-percha.
6.There were significant differences between the single thermoplasticized gutta-percha filling group and the other three groups with paste (P < 0.05), but no significant differences between ZOE, Vitapex and AHplus paste (P >0.05).
7.Class 17 Rubber, gutta-percha, gum, asbestos, mica and goods made from these materials and not included in other classes; plastics in extruded form for use in manufacture; packing, stopping and insulating materials; flexible pipes, not of metal.
8.The apex micro effusion and micro-chink of lateral condensation group are significantly larger than the other two groups (P<0.05). However, there was no statistical difference between the two injection thermoplasticized gutta-percha technique groups (p>0.05).
10.The result shows that the formula (NR 50phr, BR 30phr, Gutta-Percha 20phr, stearic acid 5phr, magnesia 2phr, zinc oxide 2phr, antioxidant D 1phr, high abrasion fine furnace black 50phr, aromatic oil 5phr, sulfur 2phr, accelerant DM 2phr) is the most excellent.
