Abstract

Objectives

This study aimed to compare the effect of four decontamination methods on the level of residual contaminants in the re-usage of dental healing abutments.

Materials and methods

In this experimental study, 50 used healing abutments were divided into five groups of ten as follows: 1. Control group: healing abutments were submerged in the ultrasonic device then autoclaved at 121 °C for 15 min; 2. Hypochlorite group: Same procedure as the control group, but the healing abutments were additionally immersed in 3 % hypochlorite for 20 min; 3. Chlorhexidine group: Same procedure as the control group, but the healing abutments were additionally treated with 12 % chlorhexidine; 4. Air polishing group: Same procedure as the control group, but the healing abutments were subjected to air polishing; 5. Hydrogen peroxide group: Same procedure as the control group, but the healing abutments were additionally exposed to 3 % hydrogen peroxide. Then, all healing abutments were stained with a protein-specific stain, Phloxine B. Five photographs were taken of each healing abutment, with four capturing the body (shank)and one capturing the top. All images were analysed, to measure the stained (contaminated) areas of each sample. The obtained data were analysed using statistical software (significance set at p < 0.05).

Results

The one-way ANOVA test indicated that the average percentage of contamination residues on the occlusal surface did not show a significant difference among the five groups: control: 5.5 ± 2.8, sodium hypochlorite: 4.9 ± 2.5, Chlorhexidine: 5.3 ± 2.5, air polisher: 3.1 ± 1.8 and Hydrogen peroxide: 4.8 ± 3.1. (p = 0.26). The average percentage of residual contamination on the body surfaces (shank part) was significantly lower in the air polisher (1.7 ± 1.1) and sodium hypochlorite (2.4 ± 1.1) groups compared to the other three groups (Control: 6.1 ± 2.3, Hydrogen peroxide: 4.6 ± 0.7, Chlorhexidine: 5.4 ± 2.4) (p < 0.05).

Conclusion

The results of this study showed that the use of sodium hypochlorite and air polishing, alongside autoclaving and ultrasonic cleaning, effectively reduced residual contamination on the body surfaces of healing abutments.

再利用愈合基台中四种去污程序的比较：体外研究

材料和方法在这项实验研究中，50 个使用过的愈合基台被分为以下五组，每组 10 个：1.对照组：将愈合基台浸没在超声波装置中，然后在 121 °C 下高压灭菌 15 分钟；2. 次氯酸盐组：程序与对照组相同，但将愈合基台另外浸泡在 3%的次氯酸盐中 20 分钟；3.洗必泰组：程序与对照组相同，但将愈合基台另外用 12% 洗必泰处理；4.空气抛光组：程序与对照组相同，但对愈合基台进行空气抛光；5.过氧化氢组：程序与对照组相同，但将愈合基台额外暴露于 3% 过氧化氢中。然后，用蛋白特异性染色剂 Phloxine B 对所有愈合基台进行染色。对每个愈合基台拍摄五张照片，其中四张拍摄主体（柄），一张拍摄顶部。对所有图像进行分析，测量每个样本的染色（污染）区域。结果单因素方差分析结果表明，五组样本咬合面上污染残留物的平均百分比没有显著差异：对照组：5.5 ± 2.8，次氯酸钠组：4.9 ± 2.5，次氯酸钠组：4.9 ± 2.5，次氯酸钠组：4.9 ± 2.5，次氯酸钠组：4.9 ± 2.5，次氯酸钠组：4.9 ± 2.5，次氯酸钠组：4.9 ± 2.5，次氯酸钠组：4.9 ± 2.5：对照组：5.5 ± 2.8；次氯酸钠组：4.9 ± 2.5；洗必泰组：5.3 ± 2.5；空气抛光机组：3.1 ± 1.8；双氧水组：4.8 ± 3.1：4.8 ± 3.1. (p = 0.26).与其他三组相比，空气抛光剂组（1.7 ± 1.1）和次氯酸钠组（2.4 ± 1.1）体表（柄部）残留污染物的平均百分比明显较低（对照组：6.1 ± 2.3；双氧水组：4.6 ± 0.结论本研究结果表明，在高压灭菌和超声波清洗的同时使用次氯酸钠和空气抛光，可有效减少愈合基台体表面上的残留污染。
