gutta
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);
3.The results showed aspergillus niger BN was the optimal fungus, and the productive rate of gutta-perch increased 13.3%.
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.The result indicated that the irritation of the MPU 03 material on periapical tissue was less than the root canal sealer and Gutta percha( P < 0.01).
7.All the root canal in the experimental groups were obturated with ObturaⅡthermoplasticized gutta - percha injection technique. The root canals in the group A, B, C were separately sealed with ZOE, Vitapex and AHplus paste, and the specimens in the group D were filled without any paste.
8.In high,middle and low dose of Qixuanyixin Capsules groups,the levels of NF-κBp50,IκBαand IL-1β protein and mRNA were lower than in the model group(P<0.05),and the effect of Qixuanyixin Capsules was better than that of Danshen Gutta Pills and Minidiab(P<0.05).
9.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.
10.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).
