دراسة جرثومية مقارنة بين فعالية محلول كيوميكس و محلول هيبوكلوريت الصوديوم في إنقاص التعداد الجرثومي في الأقنية الجذرية العفنة : دراسة سريرية

الملخص EN

Aim of study: It is to Compare the ability of Qmix and sodium hypochlorite 5,25% solutions on the microbial reduction in infected root canals .

Materials and methods: 40 extracted mandibular premolars with a single root canal have been chosen, the tooth was isolated, the pulp champer was opened, and the working length was measured.

After that, the bacterial swab was taken by size 15 sterilized paper points, then the root canals were prepared with rotary protaper instrument till F3 and irrigated with sodium hypochlorite 5,25%.

After preparation, the second bacterial swab was taken for each canal.

Later the whole samples were divided into two groups according the final rinse used: sodium hypochlorite 5,25%, and QMix.

Each group was divided to two sub-groups according to the incubation method in aerobic and anaerobic conditions.

Each sample was irrigated with 2ml of the examined solution at room temperature for 40 seconds and the solution was left inside the canal for 30 seconds.

After the irrigation, the third swab was taken for the whole sample.

Results: The Bacterial No Reduction Log(10) Percent in the sodium hypochlorite 5,25% group was greater than QMix group in both incubation mediums and in the whole sample; also, the percentage of full cleansing in the sodium hypochlorite group was greater than those of Qmix Solution Group.

Conclusions: Sodium hypochlorite 5,25%, showed higher effectiveness than QMix on the microbial reduction in infected root canals when it was used as a final rinse
