【摘要】 目的通过临床和实验研究,确定氢氧化钙牙胶尖的杀菌作用和临床应用效果,并通过对比研究,找出其适应证。方法选取乳牙慢性牙髓炎、乳牙慢性根尖周炎和年轻恒牙外伤露髓病例进行根管封药,观察临床效果,并在临床上比较氢氧化钙牙胶尖、樟脑酚(CP)、甲醛甲酚(Fc)根管封药效果。结果乳牙慢性牙髓炎和年轻恒牙露髓患儿,封药一周后原有症状基本消失,对慢性根失周炎也有一定疗效。氢氧化钙牙胶尖封药后效果强于CP,根尖反应小于Fc。结论氢氧化钙牙胶尖适用于乳牙、年轻恒牙根管内封药,可以推广使用。更多还原

【Abstract】 Objective To determine the bactericidal ability and effectiveness of Ca(OH)2 percha and clinical application criteria. Methods Patients with chronic pulpitis or chronic apical disease in primary teeth or pulp exposure after trauma in young permanent teeth were included in the study. Three (3) bactericides were used for root canal disinfection including Ca(OH)2 percha, camphophenic (CP) , and formocresol (FC) . The antibacterial effectiveness of the three (3) reagents was evaluated. Results For primary teeth with chronic pulpitis and the young permanent teeth with pulp exposure after trauma, the original symptoms usually disappear one week after the root canal disinfection. All of the three (3) bactericides showed partially curative effect in chronic apical disease. The treatment with Ca(OH)2 percha demonstrated a significantly better effect than the CP, with less apical reaction than FC. Conclusion Ca(OH)2 percha is appropriate for primary and young permanent teeth as root canal disinfection and could be widely use in pediatric dentistry.更多还原
