Objective: To evaluate the effect of overfilling with zinc oxide eugenol (ZOE) on root canal therapy (RCT) for primary tooth. 观察ZOE碘仿糊剂根充超充对乳牙根管治疗疗效的影响。
Modified method of the preparation of isoeugenol through isomerization of eugenol in the presence of 4 times theoretical amount of KOH with eugenol type basil oil as the starting material is stated. 本文叙述以丁香罗勒油为原材料用4倍理论量的氢氧化钾为催化剂进行异构化制备异丁香酚的改进方法。
Eugenol/juːɡɛnɒl/ is a phenylpropene, an allyl chain-substituted guaiacol. Eugenol is a member of the phenylpropanoids class of chemical compounds. It is a colourless to pale yellow oily liquid extracted from certain essential oils especially from clove oil, nutmeg, cinnamon, basil and bay leaf. It is present in concentrations of 80–90% in clove bud oil and at 82–88% in clove leaf oil.
