Abstract
Calcium hydroxide is used as a root canal medicament with its several pharmacological effects. However, it has been known that the usage of calcium hydroxide in the root canal system before canal filling with gutta-percha and zinc oxide eugenol-based cement induced change in the properties of root canal cement which might adversely affect sealing ability of the canal filling. The purpose of this study was to identify the reactivity of calcium hydroxide-eugenol compound made from chemical interaction of between calcium hydroxide and zinc oxide eugenol. Chemical properties of calcium hydroxide, eugenol, zinc oxide eugenol, calcium hydroxide-eugenol and calcium hydroxide-zinc oxide eugenol compound were analyzed using XRD. FT-IR Spectrophotometer and FT-NMR Spectrometer. The results were as follows: 1. The compound made from interaction between calcium hydroxide and zinc oxide eugenol was as follows : 2. Calcium hydroxide was shown to make chemical bond (ionic bond) with eugenol. 3. Since bonding between
수산화칼슘은 여러 약리작용으로 인해 근관소독제로 널리 사용되고 있는 약제이다. 근관 내에 수산화칼슘을 투약한 후 gutta-percha와 더불어 산화아연-유지놀계 근관시멘트로 근관을 충전하는 경우 근관시멘트의 물성에 변화가 있다는 보고가 있다. 따라서 본 연구에서는 수산화칼슘과 산화아연-유지놀 간의 반응에 의해 생성되는 수산화칼슘-유지놀 화합물의 반응성을 확인하기 위하여 수산화칼슘, 유지놀, 산화아연-유지놀, 수산화칼슘-유지놀 및 수산화칼슘-산화아연-유지놀 화합물을 XRD, FT-IR spectrophotometer 및 FT-NMR spectrometer로 분석하여 다음과 같은 결과를 얻었다. 1. 수산화칼슘과 산화아연-유지놀 간의 반응으로 생성된 화합물은 다음과 같았다. 2. 수산화칼슘은 유지놀과 화학결합(이온결합)을 하는 것으로 나타났다. 3.
