Aim of this trial was to evaluate the combined clinical and radiographic success rate of endodontic treatment using passive ultrasonic irrigation (PUI) and laser activated irrigation (LAI) as compared to conventional syringe irrigation.
Permanent incisors and single rooted premolars were assessed for eligibility and 69 patients were randomly divided into three treatment groups (n=23) by allocation concealment method and irrigation was performed in accordance with the allocated group. Teeth were evaluated clinically and radiographically with CBCT after 6 months and 12 months of the treatment.
A significant difference was observed in the radiographic healing rates among three groups (χ2=12.29, =0.05). On comparing the final outcome among the three groups (n=19), it was found that 2 (10.5%) cases of group I(Conventional Syringe irrigation), 7 (36.8%) cases of group II (Passive ultrasonic irrigation) and 8 (42.1%) cases of group III(Laser activated irrigation) were healed while under healing category 13 (68.4%) cases of group I, 12 (63.2%) cases of group II and 11 (57.9%) of group III were observed whereas 4 (21.1%) cases were categorised as diseased in group I only.

本试验的目的是评估与传统注射器冲洗相比，使用被动超声冲洗（PUI）和激光激活冲洗（LAI）进行根管治疗的临床和影像学成功率。
评估恒切牙和单根前磨牙是否符合纳入标准，采用分配隐藏法将69例患者随机分为三个治疗组（n = 23），并根据分配的组进行冲洗。治疗6个月和12个月后，对牙齿进行临床和CBCT影像学评估。
三组间影像学愈合率存在显著差异（χ2 = 12.29，P = 0.05）。比较三组（n = 19）的最终结果发现，I组（传统注射器冲洗）有2例（10.5%）愈合，II组（被动超声冲洗）有7例（36.8%）愈合，III组（激光激活冲洗）有8例（42.1%）愈合；而在愈合类别方面，I组有13例（68.4%），II组有12例（63.2%），III组有11例（57.9%）；仅I组有4例（21.1%）被归类为患病。
