Sažetak
Aim: To evaluate the amount of apically extruded 3% sodium hypochlorite (NaOCl) using two modes of Er:YAG laser activated irrigation (LAI) i.e. Super Short Pulse (SSP) and Shock Wave Enhanced Emission Photo- acoustic Streaming (SWEEPS®) combining three types of laser tips (LT), and conventional needle irrigation (NI). Methodology: Twenty extracted human maxillary central incisors, which had been previously prepared with Reciproc® instruments (size 40, taper 0.06) with standardized working length were selected. Irrigant volumetric flow rate (VFR) was accurately standardized using a precision syringe pump (PSP) with constant irrigant delivery through the 27gauge (G) needle. The tested irrigation protocols (duration 60s) were: Group 1. SSP (Er:YAG laser, LightWalker AT, Fotona):10 mJ, 15 Hz, pulse duration 50 μs ; Group 2. AutoSWEEPS (ASWEEPS, Er:YAG laser, LightWalker, AT, Fotona): 20 mJ, 15 Hz, pulse duration 25 µs ; Group 3. 27 G NI constant VFR 0.05 ml/s. In the SSP and ASWEEPS groups, three LT-s were used: X-Pulse 600/14 cylindrical ; SWEEPS 600 saphire ; PIPS 600/9 quartz tapered. Each protocol with three types of LT-s was evaluated in 20 teeth (10 repetitions on each). Apically extruded irrigant was collected and net weighed for each protocol. Data were analyzed by Friedman's Two-Way Analysis of Variance and Dunn’s Pairwise test with the significance level was set at p ≤ .05. Results: Significantly lower amounts of extruded irrigant during NI and SSP mode using X-Pulse and PIPS LT-s compared to other tested LAI protocols (p<0.05) were found. In the ASWEEPS group, all three LT-s resulted in similar amounts of extruded irrigant (p>0.05). Conclusion: In straight root canals, the amount of irrigant extrusion with X-Pulse and PIPS LT-s used with SSP mode of Er:YAG LAI was at the same level of needle-syringe irrigation and can be considered a safe technique.
