Abstract
One of the most important reasons of endodontic treatment failure is the persistence or survival of microorganisms in the complex root canal system or periapical area; therefore, the success of endodontic treatment depends, to a great degree, on the elimination of microorganisms from the root canal system through mechanical instrumentation and chemical irrigation. Profound irrigation of the canals with antimicrobial solutions is an important step to decrease the number of microorganisms or eliminate them from the root canal system. E.s faecalis has been reported in high prevalence in primary endodontic infections affecting children.
The purpose of this study was to compare the antimicrobial effect of Allium sativum oil with chlorhexidine 2% when used as root canal irrigants in extracted primary teeth contaminated with E. faecalis bacteria.
Forty extracted primary teeth were decoronated and only the roots were used in this study, randomly divided into two experimental groups, one positive control group and one negative control group as follows: group I: consisted of 15 roots that were irrigated with 2% Chlorhexidine digluconate solution, group II: consisted of 15 roots that were irrigated with Allium sativum oil, group III (positive control): consisted of 5 roots that were contaminated and irrigated with sterile saline and group IV (negative control): consisted of 5 roots that were not contaminated nor irrigated.
After mechanical preparation of the root canals employing the step back preparation technique reaching master apical file size #40 to standardize the diameter of all the canals, sterilization of all samples were carried out using Andromeda vacuum xp autoclave at 121 degree °C and 15 PSI pressure for 15 minutes.Bacterial contamination with the E. feacalis of the first three groups were carried out, assigning each group to its selected irrigation solution for 5 minutes then samples were collected from the canals using sterile paper points and colony-forming units of bacteria were enumerated.
There was a significant difference between the three tested groups. Positive control group had the highest (Mean±SD) bacterial count followed by the Allium sativum group while CHX group had the lowest (Mean±SD).
For the reduction percentage change, CHX group showed a significantly higher (Mean±SD) value than Allium sativum group which indicates that a 2% CHX irrigation has a higher bacterial efficacy against E. faecalis than Allium sativum irrigation solution.
Within the limitations of this study, it was concluded that antibacterial properties of allium sativum irrigation is effective but not as effective as CHX irrigation in treating infected primary teeth.
