(PO148) Comparative Efficacy of Er:YAG Laser-Activated Triton and Traditional Irrigants in Endodontic Disinfection

Abstract:
Endodontic success relies on effective biofilm eradication. While traditional sodium hypochlorite and EDTA irrigation are standard, their efficacy in the apical region is questioned. Triton solution activated by Er:YAG laser may enhance bacterial removal. This study compares both irrigation methods to evaluate Triton’s potential advantages. To assess the effectiveness of Er:YAG laser-activated Triton solution against sodium hypochlorite and EDTA in decontaminating maxillary central incisors' apices, twelve human maxillary central incisors contaminated with E. faecalis were incubated for 28 days to create biofilm growth. Teeth were randomly assigned to three groups for treatment. Standardized instrumentation to a 30/.04 size was followed by group-specific laser-activated irrigation protocols. Laser activation, including settings and time of activation, were consistent for all teeth. Group 1 (n=5) received Triton solution, Group 2 (n=5) sodium hypochlorite and EDTA, and Group 3 (n=2) distilled water as control. All teeth were then bisected longitudinally, prepared, and examined using scanning electron microscopy and scored according to cleanliness and degree of biofilm removal in the apical 4mm. This study is currently in progress with no final data available. The results will be analyzed and presented. Upon completion, the study may provide additional insights into optimizing disinfection irrigation protocols in endodontics.
