Hard tissue debris removal from the mesial root canal system of mandibular molars with ultrasonically and laser-activated irrigation: a micro-computed tomography study
This study is to investigate the efficacy of different irrigant activation techniques on removal of accumulated hard tissue debris ( AHTD ) in mesial roots of human m and ibular molars . Extracted human m and ibular molars with an isthmus between the mesial root canals were selected based on micro-CT ( μCT ) scans . The mesial canals were instrumented to an apical diameter ISO30 using ProTaper rotary files . Teeth were r and omly assigned to three irrigant activation groups ( n = 10 ) : ultrasonically activated irrigation ( UAI ) using a size 20 Irrisafe for 3 × 20 s , laser-activated irrigation ( LAI ) with an Er : YAG laser ( 2940 nm ) and plain 300 μm fiber tip inside the canal ( 20 mJ , 20 Hz , 3 × 20 s ) , and laser-activated irrigation with identical parameters with a 400 μm photon-induced photoacoustic streaming ( PIPS ) tip held at the canal entrance . All teeth were scanned with μCT before and after instrumentation and after irrigant activation . After reconstruction and image processing , the canal system volume filled with hard tissue debris before and after irrigant activation was calculated . Changes in hard tissue debris volumes were compared between groups using one-way ANOVA . The percentage volume of hard tissue debris ( vol% ) was significantly lower after irrigant activation in all groups . Although the lowest debris values were observed in the laser groups , no significant differences in the vol% of accumulated hard tissue debris after activation were observed between groups . Accumulated hard tissue debris was reduced significantly in all activation groups . Ultrasonically and laser-activated irrigation regimens performed similarly in this respect . None of the tested methods was able to render the root canal systems free of debris
