摘要
本研究旨在利用光学热成像技术评估五种不同商业品牌的杜仲胶的热行为。研究了不同顶距下的温差和换热特性。材料和方法:测试了以下品牌的杜仲胶锥:Autofit Greater锥度,Protaper Gold F2, TruNatomy Prime, ZARC杜仲胶点# 25/0.06和Reciproc Blue R25。一个特定的加热系统被用来使锥体进行热成像。测量在1-,2-,3-和4-mm的顶端距离为5毫米和10毫米的锥体长度。统计分析包括学生t检验和方差分析,显著性水平为0.05。结果:在组内比较,我们发现在热行为的细微差别时,检查杜仲胶锥长度(5毫米与10毫米)。鼻切开术表现出统计学上显著的差异(PPPPP°C)。结论:不同牌子的杜仲胶的热行为差异显著,对根管治疗有影响。虽然在传热和最高温度方面观察到差异,但所有品牌都保持在临床使用的安全温度范围内。了解这些变化可以帮助临床医生根据具体的临床情况选择合适的杜仲胶,最终优化根管封闭质量。
Thermal Behavior Variations among Commercial Gutta-percha Brands: An Optical Thermography Study.
Introduction: This study aimed to assess the thermal behavior of five different commercial gutta-percha brands using optical thermography. We focused on temperature differences and heat transfer characteristics at different apical distances.
Materials and methods: Gutta-percha cones from the following brands were tested: Autofit Greater Taper, Protaper Gold F2, TruNatomy Prime, ZARC Gutta-percha points # 25/0.06, and Reciproc Blue R25. A specific heating system was used to subject the cones to thermal imaging. Measurements were taken at 1-, 2-, 3-, and 4-mm apical distances for 5 mm and 10 mm cone lengths. Statistical analyses included Student's t-tests and Analysis of Variance with the significance level set at 0.05.
Results: Upon intragroup comparison, we found subtle distinctions in thermal behavior when examining gutta-percha cone lengths (5 mm versus 10 mm). TruNatomy exhibited statistically significant variations (P<0.05) at 2- and 3-mm distances. Conversely, ZARC and Reciproc Blue R25 displayed notable differences (P<0.05) at 2-, 3-, and 4-mm distances. In contrast, Autofit Greater Taper and Protaper Gold F2 consistently diverged across all distances (P<0.05). In intergroup comparisons of 5 mm length, significant variances (P<0.05) emerged among brands at 1- and 2-mm distances. At 10 mm length, TruNatomy differed significantly (P<0.05) from other brands across all distances. The heat tip maintained an average maximum temperature of 154.54°C.
Conclusion: Thermal behavior of gutta-percha brands varied significantly, with implications for endodontic treatments. While differences were observed in heat transfer and maximum temperatures, all brands remained within safe temperature ranges for clinical use. Understanding these variations can aid clinicians in selecting appropriate gutta-percha for specific clinical scenarios, ultimately optimizing root canal obturation quality.
期刊介绍:
The Iranian Endodontic Journal (IEJ) is an international peer-reviewed biomedical publication, the aim of which is to provide a scientific medium of communication for researchers throughout the globe. IEJ aims to publish the highest quality articles, both clinical and scientific, on all aspects of Endodontics. The journal is an official Journal of the Iranian Center for Endodontic Research (ICER) and the Iranian Association of Endodontists (IAE). The Journal welcomes articles related to the scientific or applied aspects of endodontics e.g. original researches, systematic reviews, meta-analyses, review articles, clinical trials, case series/reports, hypotheses, letters to the editor, etc. From the beginning (i.e. since 2006), the IEJ was the first open access endodontic journal in the world, which gave readers free and instant access to published articles and enabling them faster discovery of the latest endodontic research.
