Objective

To evaluate the effectiveness of photon-induced photoacoustic streaming (PIPS), a laser-activated irrigation system, in removing organic tissue and debris from root canal isthmuses, using high-resolution micro-computed tomography (micro-CT).

Materials and Methods

  • : 14 extracted human mandibular molars; mesial canals prepared to size 30/.06.

  • :

    • Standard needle irrigation (SNI) (n = 7)

    • Laser-activated PIPS irrigation (n = 7)

  • :

    • Canals scanned with micro-CT before and after irrigation.

    • Quantitative analysis of canal volume changes and debris removal by superimposing pre- and post-irrigation scans.

  • : 2-way ANOVA and Tukey method; significance set at α = 0.05.

Key Results

  • PIPS irrigation resulted in a significantly greater increase in canal volume and debris removal compared to SNI (P < .001 vs. P = .04).

  • PIPS eliminated debris 2.6 times more effectively than SNI.

Conclusions

Laser-activated PIPS irrigation is significantly more effective than standard needle irrigation in removing organic tissue and debris from complex root canal systems in mandibular molars, as demonstrated by high-resolution micro-CT analysis.
