“…An in vitro research conducted by Souza et al was also focused on the effectiveness of a high-power diode laser in association with chemical auxiliary substances on bacterial decontamination of root canal system. 29 A total power of 3 W was applied in 4 short cycles of 6 s each. Four cycles of laser radiation were able to reduce 65.4% of E. faecalis colonies.…”

AIM: To evaluate antimicrobial effect of diode laser when used adjunctively with sodium hypochlorite, methylene blue or toluidine blue in Enterococcus faecalis inoculated root canals. METHODOLOGY: 70 extracted uniradicular premolars were prepared with ProTaper files and sterilized. 5 were kept aside as negative control (G1) and the remaining 65 were inoculated with Enterococcus faecalis and incubated for 7 days. Following this, 5 were kept as positive control (G2) and the other 60 were randomly distributed into six groups: G3, diode laser irradiation (1.5W) with sodium hypochlorite; G4, diode laser (3W) with sodium hypochlorite; G5, diode laser (1.5W) with methylene blue; G6, diode laser (3W) with methylene blue; G7, diode laser (1.5W) with toluidine blue; G8, diode laser (3W) with toluidine blue. Subsequently, turbidity was assessed and CFU count determined following intracanal sampling and plating. RESULTS: G4 exhibited significantly lower mean CFUs/mL (P˂0.001) among the experimental groups. G4 demonstrated the most (98.8%) while G7 exhibited the least antibacterial effect (28.66%). Highest turbidity was observed in G5 (0.1310) while the lowest was noted in G4 (0.0287). CONCLUSION: Diode laser used adjunctively with sodium hypochlorite exhibited superior antibacterial efficacy when compared to its use with photosensitizer dyes like methylene blue and toluidine blue.
