Abstract

AIM

To compare the antimicrobial effects of two different irrigation solutions activated with erbium, chromium-doped yttrium, scandium, gallium and garnet (Er,Cr:YSGG) laser or an ultrasonic system and a photodynamic therapy (PDT) on ().

MATERIALS AND METHODS

The root canals of 72 single-rooted human permanent incisors were prepared with ProTaper Universal rotary instruments and incubated with (ATCC 29212) for 4 weeks. Then the teeth were randomly divided into seven experimental groups with 10 specimens for canal disinfection procedures. Group I, standard needle irrigation (SNI) with 2.5% sodium hypochlorite (NaOCl); group II, SNI with 2% chlorhexidine gluconate (CHX); group III, laser-activated irrigation (LAI) by Er,Cr:YSGG of NaOCl; group IV, LAI of CHX; and group V, passive ultrasonic irrigation (PUI) of NaOCl; group VI, PUI of CHX; group VII, PDT. The remaining two teeth were used as the control group. After the disinfection procedures were completed, the root canals were filled with phosphate-buffered saline and bacterial samples were taken with sterile paper cones. The cultivation was performed on Mueller-Hinton agar (MHA) plates. The live bacteria were calculated by counting the colonies on these plaques. The statistical analysis was performed using Kruskal-Wallis test and Miller's multiple comparison technique.

RESULTS

Both LAI and PUI of NaOCl and PUI of CHX were more successful than the PDT on root canal disinfection ( < 0.05).

CONCLUSION

Within the limitation of the present study, the activation of NaOCl solution by Er,Cr:YSGG laser or an ultrasonic system can be useful in the elimination of the from the canal. The PUI of CHX also has similar results. Photodynamic therapy showed a lower performance compared to these methods.

CLINICAL SIGNIFICANCE

The activation of the sodium hypochlorite with Er,Cr:YSGG laser or PUI may be useful for removal of the biofilm layer in the root canal.

摘要

目的

比较两种不同冲洗液在掺铒、铬的钇、钪、镓石榴石（Er,Cr:YSGG）激光或超声系统激活下以及光动力疗法（PDT）对（）的抗菌效果。

材料与方法

用ProTaper通用旋转器械预备72颗单根人恒牙切牙的根管，并用（美国典型培养物保藏中心29212）孵育4周。然后将牙齿随机分为7个实验组，每组10个样本用于根管消毒程序。第一组，用2.5%次氯酸钠（NaOCl）进行标准针管冲洗（SNI）；第二组，用2%葡萄糖酸氯己定（CHX）进行SNI；第三组，用Er,Cr:YSGG激光激活NaOCl进行激光激活冲洗（LAI）；第四组，用Er,Cr:YSGG激光激活CHX进行LAI；第五组，用NaOCl进行被动超声冲洗（PUI）；第六组，用CHX进行PUI；第七组，进行PDT。其余两颗牙齿作为对照组。消毒程序完成后，用磷酸盐缓冲盐水填充根管，并用无菌纸尖采集细菌样本。在穆勒-欣顿琼脂（MHA）平板上进行培养。通过计算这些菌斑上的菌落数来计算活菌数。采用Kruskal-Wallis检验和米勒多重比较技术进行统计分析。
