Experimental Study on the Effect of Apical Sealing of Different Warm Gutta Percha Root Canal Obturation in the Oblate Canal
摘要
Abstract
Objective To compare the effect of apical sealing with the different warm gutter percha obturation in the oblate canal after the post space preparation. Methods To select 90 single oblateroot canal from the first mandibular premolar,crowned the crownand unified the working length of 14mm, randomly divided into three groups of 30. The root canal preparaed with the ProTaper next nickel titanium system under the dental operating microscope. The rootcanal obtured with the warm gutta-percha vertical condensation technique, thermoplastic core-carrier technique andcold lateral condensation technique, then use 1-4#Pesso to remove the gutta percha and prepare the post space, the depth is 9mm. For the cross-sectional slice at 3mm from the apical, recorded the proportion of paste and voids in the root canal section. To analyze the effect of different obturation measure in the apical sealing after the post space preparation of the oblate root canal. Results Two kinds of warm gutta percha obturation group in the apical 3mm, the apical sealing effect is obviously better than cold lateral condensation group (P<0.05). Warm gutta-percha vertical condensation technique group is slightly better than the tthermoplastic core-carrier technique obturation group, but no statistical difference (P>0.05). Conclusion Use the warm gutta-percha vertical condensation technology in the oblatecanalobturation could get the well apical sealing effect after the post space preparation.关键词
