Laser Activation Irrigant Tip Position Effect Ex Vivo Study.
Objectives: Laser activated irrigation (LAI) has shown effectiveness in removing the smear layer in endodontics,This study evaluated the effectiveness of the Er,Cr:YSGG laser tip positioned in the apical and coronal segments for LAI using two irrigants.
Methods: A total of 35 single-rooted human mandibular teeth were selected for the study. Teeth were decoronated The samples were then divided into seven equal groups (n = 5). The images obtained through SEM were independently scored by two blinded observers using a 5-point scoring system.
Results: The control group demonstrated a statistically significant difference compared to the other groups (p < 0.05). with the highest presence of smear layer . The apical LAI group with 0.5% sodium hypochloriteachieved the best smear layer removal and the greatest number of open dentinal tubuli
Conclusions: Laser activation of 0.5% sodium hypochlorite demonstrates a positive effect on smear layer removal, particularly when the laser tip is positioned in the apical zone. When tip is at the coronal zone they reduced the efficacy on smear layer removal at the apical third.
