Root canal irrigation with citric acid solution

Calcium hydroxide has been widely used as intracanal medicament recently. However, removing calcium hydroxide accumulated in the apical foramen was difficult, and there is a risk of overflowing outside of the apical foramen during removing procedure. In this study, we investigated (1) the status of overflow from root apex foramen in each removal method using hand file or ultrasonic scaler, (2) possibility of reducing overflow in combination with citric acid solution or EDTA solution. Twenty-four maxillary premolar artificial teeth were performed root canal enlargement using K-fail until No.25 or No.30 size of thickness in each 12 teeth. After finishing root canal enlargement, calcium hydroxide was filled within root canal apex completely. Then calcium hydroxide was removed using ultrasonic scaler or hand file. Furthermore purified water, citric acid solution or EDTA solution was prepared as auxiliary agents respectively. After removing calcium hydroxide from each root canal was finished, the condition of calcium hydroxide overflowing from root apex was observed using stereomicroscope. Calcium hydroxide in the root canal was sufficiently removed from root canals in the groups using ultrasonic scaler. However slighted calcium hydroxide was remained around root apex in the groups using hand file. Overflow of calcium hydroxide to outside around root apex was observed both using ultrasonic scaler and hand file. The tendency of calcium hydroxide overflowing was higher in the case of using ultrasonic scaler than using hand file. In the groups of using hand file, no significant difference was observed for the different size of root canal enlargement, however overflow of calcium hydroxide was clearly higher in 30 size of root canal enlargement using ultrasonic scaler. The use of citric acid solution and EDTA solution as auxiliary agents showed that overflow of calcium hydroxide was decreased compared without using them. In particular, the decrease of overflowing was more clearly using citric acid solution than using EDTA solution. It is recommended that using hand file on removal apex areas of calcium hydroxide to reduce amount of overflowing and improve the removal efficiency. Moreover reducing the risk of calcium hydroxide overflowing are expected using citric acid solution or EDTA solution.

The aim of this study was to evaluate efficacy in smear layer removal of 17% EDTA and 10% citric acid, using SEM. Material and method: Twenty human, extracted teeth with a single root canal were examined. Whilst instrumentation with step-back technique and manual K files, root canals were irrigated with 2 ml of 2.5% NaOCl, between each file size. After instrumentatio n, specimens were divided into two groups. The first group was irrigated with a final flush of 17% EDTA, during one minute, and the second group was irrigated with a 10% citric acid. Results: Irrigation with 17% EDTA and 10% citric acid removed smear layer from the root canals walls. There was not statistically significant differences (p>0.05) in cleaning ability between EDTA and citric acid groups.

ABSTRACT Microorganisms and their by-products play a critical role in pulp and periradicular pathosis. Therefore, one of the main purposes of root canal treatment is disinfection of the entire system of the canal. This aim may be obtained using mechanical preparation, chemical irrigation, and temporary medication of the canal. For this purpose, various irrigation solutions have been advocated. Common root canal irrigants, such as sodium hypochlorite, chlorhexidine, and a mixture of tetracycline, acid, and detergent have been extensively reviewed. The aim of this review was to address the less common newer root canal irrigation solutions, such as citric acid, maleic acid, electrochemically activated water, green tea, ozonated water, and SmearClear.

Abstract Background This study aimed to compare the use of photon-initiated photoacoustic streaming (PIPS) and conventional needle irrigation (CNI) in conjunction with different concentrations of sodium hypochlorite (NaOCl) to remove Enterococcus faecalis (E. faecalis) suspended bacteria and biofilms from root canal systems with different diameters or tapers. Methods Artificial root canal samples (n = 480) were randomly divided into three groups (n = 160/group). The canals were prepared to fit file sizes #10/.02, #25/.02, or #25/.06. The size #10/.02 group was incubated for seven days. The size #25/.02 or #25/.06 group was incubated for 2 days. A stable biological model of E. faecalis infection was established. The root canals were washed with distilled water or with 1%, 2%, or 5.25% NaOCl combined with CNI or PIPS. Bacterial suspensions and biofilms were assessed using an ATP assay kit and fluorescence microscopy. Image-Pro Plus was used to analyse the average fluorescence intensity to determine the most suitable root canal irrigation solution. Results In the CNI and PIPS groups, the ATP value of the 5.25% NaOCl subgroup was the lowest, followed by that of the 2% and 1% NaOCl subgroups. The ATP value of the distilled water subgroup was the highest (P < 0.05). When the root canal taper was 0.02, the ATP value of the #10/.02 + PIPS group was significantly lower than that of the #25/.02 + CNI group (P < 0.05). The average fluorescence intensity of the #10/.02 + PIPS group was lower than that of the #25/.02 + CNI group (P < 0.05). When the apical diameter was #25, the ATP value of the 0.02 taper in the PIPS group was lower than that of the 0.06 taper in the CNI group (P < 0.05), and the average fluorescence intensity of the 0.02 taper + PIPS group was lower than that of the 0.06 taper + CNI group (P < 0.05). PIPS combined with 2% and 5.25% NaOCl effectively improved the long-term antibacterial effect after irrigation and re-culture for 6 h. Conclusions Compared with CNI, PIPS has greater ability to remove bacteria in root canals with a small preparation diameter and a small taper. PIPS with 2% and 5.25% NaOCl exhibited superior antibacterial and bacteriostatic effects.
