摘 要
钙化根管是根管治疗中的常见难题，传统方法常难以有效疏通。显微根管治疗术通过高倍放大与精准操作显著提升了处理钙化根管的能力。研究基于显微根管治疗技术基础，系统分析钙化根管的临床特征、治疗原理、器械选择及操作流程，明确其适应证与临床难点。采用回顾性病例分析方法，纳入符合标准的钙化根管患者，记录治疗过程与随访结果，评估临床疗效。统计显示，总体治疗成功率达89.3%，并发症发生率控制在合理范围。进一步分析表明，根管钙化程度、医源性操作失误及患者个体差异是影响预后的主要因素。重度钙化病例需结合超声器械与导航技术以提高通畅率。针对操作相关风险，规范流程与术者经验至关重要。患者年龄、牙位分布及既往治疗史亦对结局产生一定影响。通过优化显微技术路径，可显著提升治疗可预测性与安全性。该研究验证了显微根管治疗在复杂钙化病例中的有效性，并提出针对性干预策略，为临床实践提供可靠依据。

Abstract
Calcified root canals represent a common challenge in endodontic treatment, often difficult to negotiate using conventional methods. Microscopic endodontic treatment significantly enhances the ability to manage calcified canals through high-magnification visualization and precise instrumentation. This study systematically analyzes the clinical characteristics, therapeutic principles, instrument selection, and procedural protocols of calcified root canals based on microscopic techniques, clarifying their indications and clinical challenges. A retrospective case analysis was conducted by enrolling patients with calcified root canals who met inclusion criteria, documenting treatment procedures and follow-up outcomes to evaluate clinical efficacy. Statistical results showed an overall treatment success rate of 89.3%, with complication rates maintained within acceptable limits. Further analysis revealed that the degree of root canal calcification, iatrogenic procedural errors, and patient-specific factors were the primary determinants affecting prognosis. Severe calcification cases require integration of ultrasonic instruments and navigational technologies to improve canal patency. Standardized procedural protocols and operator experience are critical in mitigating procedure-related risks. Patient age, tooth location distribution, and prior treatment history also exerted notable influence on treatment outcomes. Optimization of microscopic technical approaches can significantly enhance predictability and safety in treatment. This study confirms the effectiveness of microscopic endodontic treatment in managing complex calcified cases and proposes targeted intervention strategies, providing reliable evidence for clinical practice.
