Abstract

ABSTRACT Gutta-percha is commonly used in endodontic therapy for obturating root canals after cleaning and shaping procedures. Warm and cold gutta-percha techniques are two common methods employed for obturation, each with its own advantages and limitations. Twenty extracted human teeth with single-rooted canals were selected and divided into two groups: warm gutta-percha obturation and cold gutta-percha obturation. In the warm gutta-percha group, gutta-percha was heated to a predetermined temperature using a warm gutta-percha heating device and injected into the root canal using a heated carrier. In the cold gutta-percha group, gutta-percha was applied directly to the root canal without prior heating. Root canal obturation quality was assessed using radiographic imaging to evaluate the presence of voids, completeness of obturation, and adaptation to the canal walls. Micro-computed tomography (micro-CT) analysis was also performed to quantify the volume of obturating material and assess the three-dimensional distribution of gutta-percha within the root canal space. Both warm and cold gutta-percha techniques demonstrated effective obturation of root canals, with comparable outcomes in terms of void formation, completeness of obturation, and adaptation to canal walls. However, micro-CT analysis revealed differences in the volume and distribution of gutta-percha within the root canal space. Warm gutta-percha obturation exhibited more uniform distribution of gutta-percha material and higher volumetric filling compared to cold gutta-percha obturation. Additionally, the warm gutta-percha technique demonstrated superior flowability and adaptation to irregularities within the root canal system. In this in vitro study, warm gutta-percha obturation demonstrated advantages over cold gutta-percha obturation in terms of volumetric filling, distribution within the root canal space, and adaptation to canal irregularities.

比较用于根管充填的温热和冰冷 Gutta-Percha 技术:体外研究
摘要 在牙髓治疗中,在完成清洁和塑形程序后,通常会使用古塔漆来封固根管。温敷和冷敷是两种常用的灌封方法,各有其优点和局限性。 我们选择了 20 颗带有单根根管的拔牙,并将其分为两组:温热古塔漆封堵法和冷古塔漆封堵法。在温热古塔波卡组,使用温热古塔波卡加热装置将古塔波卡加热到预定温度,然后使用加热载体将古塔波卡注入根管。在冷古塔波胶组中,古塔波胶无需事先加热,直接注入根管。根管封闭质量通过放射成像进行评估,以评价是否存在空隙、封闭是否完整以及与根管壁的适应性。此外,还进行了显微计算机断层扫描(micro-CT)分析,以量化封堵材料的体积,并评估根管内古塔漆的三维分布情况。 温性和冷性古塔漆技术都能有效地封堵根管,在空隙形成、封堵的完整性和对根管壁的适应性方面效果相当。然而,显微 CT 分析表明,根管内的水门汀数量和分布存在差异。与冷古塔水门汀相比,温古塔水门汀封药的古塔水门汀材料分布更均匀,填充体积更大。此外,温热的古塔漆技术还表现出了更好的流动性和对根管系统内不规则情况的适应性。 在这项体外研究中,温热古塔漆封堵术在体积填充、根管空间内的分布以及对根管不规则的适应性方面都比冷古塔漆封堵术更有优势。
