Gutta-percha (GP) gets contaminated during handling. It becomes imperative to ensure GP is sterile before placement in root canal space.
The aim of the study was to evaluate and compare the tensile strength of GP treated with four different disinfectant solutions: 3% sodium hypochlorite (NaOCl), amla juice (AJ), (AV) juice, and pancha tulsi (PT).
The study design was an study.
Fifty GP cones with a size of 30 were procured from sealed packages in five different groups. Experimental groups were disinfected for 1 min with 3% NaOCl, AJ, AV, and PT except the control group. Tensile and Brinell Testing Machine is used to measure the tensile strengths of GP.
Results were subjected to statistical analysis using the Kruskal-Wallis test followed by Dunn's test.
The mean tensile strength values for Groups A, B, C, D, and E are 9.49 Mpa, 13.33 Mpa, 12.58 Mpa, 12.69 MPa, and 13.56 MPa, respectively. In the herbal disinfectant group, such as AJ, AV, and PT, the tensile strength was not significantly altered, whereas in the 3% NaOCl group, it was reduced considerably.
AJ, AV juice, and PT as a GP disinfectant do not alter the tensile strength of GP cones.
牙胶尖（GP）在操作过程中会被污染。在将牙胶尖放置于根管空间之前确保其无菌变得至关重要。
本研究的目的是评估和比较用四种不同消毒溶液处理后的牙胶尖的拉伸强度：3%次氯酸钠（NaOCl）、印度醋栗汁（AJ）、芦荟汁（AV）和五味草（PT）。
本研究设计为一项……研究。
从密封包装中采购五十个尺寸为30的牙胶尖，分为五个不同组。除对照组外，实验组分别用3% NaOCl、AJ、AV和PT消毒1分钟。使用拉伸和布氏试验机测量牙胶尖的拉伸强度。
结果采用Kruskal-Wallis检验，随后进行Dunn检验进行统计分析。
A组、B组、C组、D组和E组的平均拉伸强度值分别为9.49兆帕、13.33兆帕、12.58兆帕、12.69兆帕和13.56兆帕。在草药消毒组，如AJ、AV和PT组，拉伸强度没有显著改变，而在3% NaOCl组，拉伸强度显著降低。
AJ、AV汁和PT作为牙胶尖消毒剂不会改变牙胶尖的拉伸强度。
