This study aimed to evaluate the effectiveness of Calvital(®), which is a calcium hydroxide formulation, on persistent apical periodontitis caused by over-enlargement of the apical foramen. The study included patients referred to the Department of General Dentistry at Tokyo Dental College Suidobashi Hospital on a diagnosis of persistent apical periodontitis at an external dental clinic. Of them, 20 showing considerable enlargement of the apical foramina were included in the study. Complete disappearance of symptoms was observed in all patients after intracanal application of Calvital(®). We believe that this was due to effective wound-healing brought about the strong alkaline nature of this formulation. We regard Calvital(®) as a highly effective agent for root canal treatment of teeth with persistent apical periodontitis.
本研究旨在评估氢氧化钙制剂Calvital(®)对根尖孔过度扩大所致持续性根尖周炎的疗效。该研究纳入了在外部牙科诊所被诊断为持续性根尖周炎并转诊至东京齿科大学水道桥医院普通牙科的患者。其中，20例根尖孔有明显扩大的患者被纳入研究。在根管内应用Calvital(®)后，所有患者的症状均完全消失。我们认为这是由于该制剂的强碱性带来了有效的伤口愈合。我们将Calvital(®)视为治疗持续性根尖周炎牙齿根管治疗的高效药物。
