Evaluation of the irrigation efficacy of chlorhexidine gel in disinfection necrotic pulp root canals of anterior primary teeth(Clinical comparative bacteriological study)

Abstract

Objectives: The study aimed to compare Qmix2in1 and sodium hypochlorite solution in eliminating Enterococcus faecalis bacteria within root canals of primary teeth.

Materials and Methods: The study sample consisted of 30 extracted primary molars, which were divided into two groups: Group 1 experimental

 (n=15) Qmix²ⁱⁿ¹, Group 2 control (n=15) 5.25% sodium hypochlorite. The root canals were prepared using Kedo-S file rotary then sterilized within autoclave and then contaminated with Enterococcus faecalis bacteria. The root canals were irrigated for 5 minutes in a quantity of 3 ml using a 31-gauge irrigation needle and then bacterial sample were taken then  the bacterial colonies were counted and converted  to logarithmic numbers..

Results: Both sodium hypochlorite and Qmix²ⁱⁿ¹ reduced the bacterial count of Enterococcus within root canals of primary molars. When comparing the two irrigant, significant statistically differences were observed (P-value = 0.001) in favor of Qmix²ⁱⁿ¹ group.

Conclusion:  : Qmix²ⁱⁿ¹ can be considered as a good alternative to sodium hypochlorite in irrigation root canals of primary teeth.
