Aim: To compare antimicrobial efficacy of QMix 2 in 1, 908 nm diode laser and their combination against E.faecalis.

Methodology: 49 single rooted extracted premolars were divided into five groups – positive control group (n=12), Group I (QMix 2 in 1) (n=12),

Group II (908 nm laser) (n=12), Group III (QMix 2in 1+Laser (n=12), negative control group (n=1). Root canal was performed. Teeth were

autoclaved and inoculated with E.faecalis infected nutrient broth except for negative control group. All groups were treated with respective

antimicrobial solutions except for positive control group. Dentin shavings were collected with paper points and CFU/mL was counted for each

group.

Results: Group I was found to be significant than Group II. Group I and Group III showed non–significant results and highest antimicrobial activity

was observed with combination.

Conclusions: QMix 2 in 1 with or without use of laser has the ability to disinfect root canal.
