Abstract


Background: It is known that no specific antifungal agent exists at present for irrigation of infected root canals. QMix 2in1 was investigated to determine whether they could be an alternative for sodium hypochlorite (NaOCl), chlorhexidine gluconate (CHX), and ethylenediaminetetraacetic acid (EDTA).

Objective: The aim of this in vitro study was to evaluate and compare the antifungal efficacy of QMix 2in1, 5.25% NaOCl, 2% CHX, and 17% EDTA as a final rinse against Candida albicans (C. albicans).

Materials and Methods: Ninety single‑rooted mandibular premolar teeth were randomly divided into four experimental (n = 20) and two control (n = 5) groups. All root canals were instrumented with Mtwo rotary file system using crown‑down technique to an apical size 40. Following root canal preparation, teeth were inoculated with C. albicans and incubated for 72 h. Teeth were irrigated with one of the following solutions as a final irrigant: (1) 5.25% NaOCl, (2) 2% CHX, (3) QMix 2in1, and (4) 17% EDTA. Aliquots from the samples were plated on 4% Sabouraud Agar, and colony‑forming units were counted.

Results: QMix 2in1, 5.25% NaOCl, and 2% CHX were equally effective (P > 0.05) and significantly superior to 17% EDTA in eradicating C. albicans (P < 0.05).

Conclusion: QMix 2in1 proved to be effective against C. albicans when used as a final rinse. According to the findings of the present study, QMix 2in1 may be recommended as an alternative final rinse solution.
