Background. Bacteria is main etiologycal factor of pulpo-periapical disease. Therefore, eliminating bacteria is the important part on root canal treatment. It can be obtained by using irrigation agent that has antibacterial effect and endodontic sterilization agent. Beside of its antibacterial effect, the ideal irrigation agent should has an ability to remove necrotic tissue and less toxic. Propolis is well known as a natural substain that has antibacterial effect and less toxicity. So, it has a potential use as irrigation agent compared with common root canal irrigation agent, sodium hypochloryte. Purpose. The aim of this study was to observed the difference of antibacterial effect between propolis solution and sodium hypochlorite. Method. Nine samples of Streptococcus viridans were prepared and each sample devided into three parts namely group P (propolis solution), group N (sodium hypochlorite), and control group S (saline). Each group was treated with 0,01 cc agent of root canal irrigation, then was stored in incubator 370C for 24 hours. After that, inhibition zone diameter of  each group was observed.Result. The average of inhibition zone diameters in sodium hypochlorite’s group was 23,47 mm; in propolis solution’s group was 18,70 mm. There were significant difference of antibacterial effect between propolis solution and sodium hypochlorite, against Streptococcus viridans.  Conclussion. Antibacterial effect of sodium hypochlorite is higher than propolis solution, but we should consider the potential use of natural agent-propolis solution as root canal irrigation due to its antibacterial effect.

ABSTRACT Objectives: This is an in vitro study to develop a formulation of a hypochlorite solution for root canal irrigation that lacks a chlorinated odor. The antibacterial effect, tissue dissolution efficacy, and the cytotoxicity of the solution were assessed in cell culture and were compared with those of commercial sodium hypochlorite (NaOCl) solutions. Materials and Methods: Trichloroisocyanuric acid (TCA) was used as the source of hypochlorite ions in solution. All required properties of the NaOCl irrigant were evaluated and compared with those of original 2.5% NaOCl solutions currently in use. Results: Our results revealed that a TCA 3.5% + 1/6 Buffer-1 solution passed the short-term stability test. Moreover, no odor of chlorine gas was detected by three independent observers. The hypochlorite ion content and pH were stable over an incubation period of 4 weeks. The new solution did not differ from commercial products in terms of the dissolution property on bovine pulpal tissue (P > 0.05). Moreover, the antibacterial effect of this solution on Enterococcus faecalis did not differ from that of the commercial products (P > 0.05). In addition, our biocompatibility analysis demonstrated no difference among the tested solutions (P > 0.05). Conclusions: According to the results of all properties tested, TCA 3.5% + 1/6 Buffer-1 could be considered an option for NaOCl irrigation with the benefit of no detectable chlorine odor.

The purpose of this study was to assess the effectiveness of endodontic irrigants in removing the smear layer from instrumented root canal walls using Scanning Electron Microscopy (SEM). The endodontic irrigants used were: 1% sodium hypochlorite (NaOCl); 1% NaOCl mixed to 17% EDTAC; 2% chlorhexidine gel; and Ricinus communis gel. Photomicrographs of the middle and apical thirds were evaluated with the aid of the Fotoscore - v. 2.0 software. The results indicated that the mixture of sodium hypochlorite and EDTAC completely removed the smear layer from dentinal walls. The other endodontic irrigants were not as efficient in cleansing the root canals.

Abstract Aim The aim of this in vitro study was to evaluate the cleaning capacity of different auxiliary chemical substances energized with ultrasound in radicular dentin using morphologic analysis. Methods and Materials Twenty-eight single-canal, mandibular incisors were prepared with the Hero 642 canal preparation system following the sequence: 25/12, 30/06, 35/02, and 40/02, 1 mm from the apex. The specimens were then divided into four groups of seven teeth. During biomechanical preparation the teeth were irrigated with 2 ml of distilled water between files. Each group of specimens (n=7) received a final irrigation with 100 ml of the following irrigants that were activated with ultrasound for 3 minutes: Group 1- distilled water; Group 2- 0.2% chlorhexidine digluconate (CHX); Group 3- 2.5% sodium hypochlorite (NaOCl); and Group 4-the filtrate obtained after combining 0.2% CHX and 2.5% NaOCl. The apical portions of the root canals from each group were then submitted to histological processing and analyzed using optical microscopy. Results Results showed statistical differences between the groups (p<0.01). Groups 1 and 2 (distilled water and 0.2% CHX respectively) were statistically similar in terms of a greater amount of debris, whereas 2.5% NaOCl and the filtrate were more efficient in removal of debris. Conclusion There is no additional benefit in terms of debris removal from root canal walls by irrigating with the filtrate obtained from the combination of NaOCl and CHX when compared to using NaOCl alone. Clinical Significance The findings of this study suggest the time and expense of preparing and using a combination of NaOCl and CHX is not warranted compared to using NaOCl alone for root canal irrigation.

Abstract Introduction Increase in efficacy during root canal irrigation may contribute to better treatment outcomes. This study investigated the efficacy of ultrasonic and negative pressure irrigation systems using sodium hypochlorite (NaOCl) in the reduction of bacterial load in human teeth. One hundred thirty-one single-rooted teeth were cleaned and shaped, autoclaved, and incubated with E. faecalis. Teeth were randomly assigned to three experimental groups (n = 40) and treated in the presence of 1% sodium hypochlorite using EndoUltra cordless ultrasonic, conventional ultrasonic, and Endovac negative pressure irrigation. Syringe irrigation controls were treated with 1% sodium hypochlorite and phosphate-buffered saline via side-vented needle irrigation. All groups with NaOCl received 5% sodium thiosulfate neutralization for 5 min after treatment. Samples of root canal fluid and dentin chips were acquired from canals before and after treatment, incubated on BHI agar, and colony forming units categorized according to quantity. Wilcoxon rank-sum and Bonferroni tests were used for statistical analysis. p values less than 0.05 were considered significant. Results Endovac group was significantly better in eliminating bacteria from the root canals than 1% NaOCl (p = 0.006) and PBS syringe irrigation (p = 0.015). However, it was not significantly different from the two ultrasonic groups (p > 0.05). Both ultrasonic groups showed better performance than 1% NaOCl and PBS syringe irrigation, however, not statistically significant (p < 0.03). There was no significant difference between the two ultrasonic devices (p > 0.05). Conclusion EndoVac may be an important tool for bacterial load reduction in oval canals.
