The aim and objective of this study was to compare the antimicrobial efficacy of 0.2% chitosan, 3% sodium hypochlorite, 2% chlorhexidine against alone and in conjunction with diode laser.
The root canals of 72 extracted intact human single-rooted teeth with single canals were prepared, and was incubated in the root canals for 7 days. The teeth were then randomly divided into the following four experimental groups: group I: Saline, group II: 0.2% Chitosan, group III: 3% Sodium hypochlorite, and group IV: 2% Chlorhexidine. These groups were further subdivided into three groups: (1) 10 mL irrigant only, (2) 10 mL irrigant, dried and irradiation with diode laser, (3) Diode laser was used for activation of irrigant solution. Samples were obtained from subgroups in each group and checked for turbidity. The effect of each irrigant was evaluated by counting the number of colony-forming units observed on inoculation with samples taken from the irrigated canal on bile esculin azide agar. The data thus obtained was recorded and put to statistical analysis.
Significant reductions were noted in colony counts in all groups ( < 0.05). The greatest reduction in colony count (0%) was noted in group IV followed by group II. Also, samples disinfected with diode laser after root canal irrigation showed less number of colony-forming units per mL as compared to the samples irrigated with root canal solutions alone or diode laser alone.
Chitosan has the capability for use as an accessory for disinfection of the root canal system. The application of an 810-nm diode laser by itself did not have the adequate antimicrobial activity to be used as an adjunct in root canal therapy. Irradiation with diode laser ought to be used in conjunction with the irrigant to gain maximum antibacterial effect against .

本研究的目的是比较0.2%壳聚糖、3%次氯酸钠、2%氯己定单独使用以及与二极管激光联合使用时的抗菌效果。
制备72颗完整拔除的人单根管单根牙的根管,并在根管中孵育7天。然后将牙齿随机分为以下四个实验组:第一组:生理盐水,第二组:0.2%壳聚糖,第三组:3%次氯酸钠,第四组:2%氯己定。这些组进一步细分为三组:(1)仅10 mL冲洗液,(2)10 mL冲洗液,干燥后用二极管激光照射,(3)用二极管激光激活冲洗液。从每组的亚组中获取样本并检查浊度。通过计算接种从冲洗后的根管中取出的样本在胆汁七叶苷叠氮化物琼脂上观察到的菌落形成单位数量来评估每种冲洗液的效果。将由此获得的数据进行记录并进行统计分析。
所有组的菌落计数均显著降低(P < 0.05)。菌落计数降低最大(0%)的是第四组,其次是第二组。此外,与仅用根管冲洗液或仅用二极管激光冲洗的样本相比,根管冲洗后用二极管激光消毒的样本每毫升的菌落形成单位数量更少。
壳聚糖有能力用作根管系统消毒的辅助剂。810纳米二极管激光自身的应用没有足够的抗菌活性用作根管治疗的辅助手段。二极管激光照射应与冲洗液联合使用,以获得对[具体细菌名称未给出]的最大抗菌效果。
