摘要

背景:氢氧化钙(Ca(OH)2)因其生物相容性和刺激硬组织形成的能力以及抗菌作用而成为盖髓治疗的金标准。然而，这种化合物的缺点是容易溶解在唾液中，这将增加在腔内泄漏的风险。另一种替代的髓盖材料是从血蛤壳中提取的碳酸钙。血蛤壳含有98%的CaCO3, CaCO3溶解度低，很难溶于水，因为Ca2+和CO32-上的离子很大，所以这些离子之间的吸引力很强，最终H2O无法分解CaCO3化合物被溶解。目的:探讨血蛤壳碳酸钙与氢氧化钙作为牙髓封盖材料的溶解度差异。方法:本研究采用前测后测对照组设计方法进行实验室实验研究。样品为12片Ca(OH)2和CaCO3，分为2组进行处理。第1组CaCO3浸泡1天，第2组Ca(OH)2浸泡1天，第3组CaCO3浸泡7天，第4组Ca(OH)2浸泡7天。溶解度根据溶解度公式计算。用Anova-Welch进行数据测试。结果:浸泡1 d和7 d的CaCO3和Ca(OH)2组溶解度差异有统计学意义(p<0.05)。结论:CaCO3在血蛤壳中的溶解度低于在Ca(OH)2中的溶解度。

Differences in the solubility of CaCO3 from blood clam shells and Ca(OH)2 as a candidate pulp capping material

Background: Calcium hydroxide (Ca(OH)2) is the gold standar in pulp capping treatment because the biocompatibility and capability to stimulate hard tissue formation and also antibacterial effect. However, this compound has the disadvantage of being easily soluble in saliva which will increase the risk of leakage in the cavity. Another alternative pulp capping material is calcium carbonate from blood clam shells. Blood clam shells contain 98% CaCO3, CaCO3 has low solubility and is difficult to dissolve in water due to the large ions on Ca2+ and CO32- so that the attractive force between these ions is very strong and finally H2O is not able to break down the CaCO3 compound to be dissolved. Purpose: Explained the differences in the solubility of calcium carbonate from blood clam shells and calcium hydroxide as candidates pulp capping materials. Methods: This research is a laboratory experimental study with a pretest-posttest control group design method. The samples consisted of 12 pieces of Ca(OH)2 and CaCO3 then divided into 2 groups and given treatment. Group 1 CaCO3 immersed in 1 day, group 2 Ca(OH)2 immersed in 1 day, group 3 CaCO3 immersed in 7 days, and group 4 Ca(OH)2 immersed in 7 days. Solubility is calculated according to the solubility formula. Data testing with Anova-Welch. Results: There was a significanly difference in the solubility rate between the CaCO3 dan Ca(OH)2 groups immersed for 1 day and 7 days on the Anova-Welch results (p<0.05). Conclusion: The solubility of CaCO3 in blood clam shells is lower than the solubility in Ca(OH)2.)
