Abstract

Aim: The aim of this study was to evaluate the amounts of apically extruded 3% sodium hypochlorite using two modes of Er:YAG laser-activated irrigation (LAI), super short pulse (SSP) and shock wave enhanced emission photoacoustic streaming (SWEEPS®) by combining three types of laser tips (FT) and conventional syringe needle irrigation (SNI).

Methods: Twenty extracted human maxillary central incisors were prepared using Reciproc® instruments (size 40, taper 0.06). The irrigant volumetric flow (IVF) was accurately standardized using a precision syringe pump with constant irrigant delivery through the 27G needle. The tested irrigation protocols (60 s) were groups 1: 27-G SNI with 0.05 ml/s constant IVF; group 2: SSP (10 mJ, 15 Hz, pulse duration 50 μs) + Radial SWEEPS FT; group 3: SSP + photon-induced photoacoustic streaming (PIPS) FT; group 4: SSP+SWEEPS FT; group 5: AutoSWEEPS (20 mJ, 15 Hz, pulse duration 25 µs) + Radial SWEEPS FT; group 6: AutoSWEEPS+PIPS FT; group 7: AutoSWEEPS+SWEEPS FT. Each protocol was evaluated in 10 repetitions each. Apically extruded irrigant was collected, and net weighted.

Results: There were significantly lower amounts of extruded irrigant with SNI and SSP using radial SWEEPS and PIPS FTs compared to the other tested laser protocols (p<0.05). In the AutoSWEEPS groups, all three FTs had similar amounts of extruded irrigant (p>0.05).

Conclusion: In straight root canals, the use of various fiber FTs in the AutoSWEEPS mode exhibited a higher potential for irrigant extrusion.

两种Er: YAG激光灌洗方式及三种激光针尖的根尖挤出。

目的：本研究的目的是利用Er:YAG激光激活冲洗（LAI）、超短脉冲（SSP）和冲击波增强发射光声流（sweep®）两种模式，结合三种激光尖端（FT）和传统注射器针头冲洗（SNI），评估根尖挤出3%次氯酸钠的量。方法：使用Reciproc®器械（尺寸40，锥度0.06）制备20颗拔除的人上颌中切牙。使用精密注射泵精确标准化冲洗体积流量（IVF），并通过27G针持续进行冲洗。试验灌洗方案（60 s）为1组：27-G SNI， 0.05 ml/s恒定IVF；2组：SSP (10 mJ, 15 Hz，脉冲持续时间50 μs) + Radial sweep FT；第3组：SSP +光子诱导光声流（PIPS） FT；第4组：SSP+ sweep FT；5组：autosweep (20 mJ, 15 Hz，脉冲持续时间25µs) + Radial sweep FT；第六组：autosweep +PIPS FT；第7组：autosweep + sweep FT。每种方案每10次重复评估。收集顶部挤出的灌溉水，并净称重。结果：与其他测试的激光方案相比，使用径向扫描和PIPS FTs的SNI和SSP挤出灌洗剂量显著减少（p0.05）。结论：在直根管中，在autosweep模式下使用各种纤维FTs具有更高的灌流挤出潜力。
