Triple antibiotic paste (TAP) is the commonly used intracanal medicament against Enterococcus faecalis. Amoxicillin clavulanate paste (ACP) is recommended as a “fall‑back” antibiotic when traditional dental antibiotics fail. Literature comparing the antimicrobial efficacy of TAP and ACP in eradicating E. faecalis from the root canal system is sparse; hence, this in vitro study was conducted to evaluate and compare the antimicrobial efficacy of TAP and ACP as an intracanal medicament for endodontic treatment of single‑rooted permanent teeth against E. faecalis.

This in vitro, experimental study evaluated 60 root samples obtained from extracted single‑rooted human permanent teeth. The canal diameter was enlarged and subsequently infected with E. faecalis for 21 days. Four groups of the contaminated samples were treated with TAP, ACP, calcium hydroxide (positive control), and saline (negative control), respectively. Dentinal shavings were collected at the end of the 1st, 7th, and 10th day and inoculated in agar plates. The number of colony‑forming units was determined, and the data were statistically analyzed using the Kolmogorov–Smirnov and Shapiro–Wilks test. P <0.05 was considered statistically significant.

The mean number of E. faecalis colony counts across all 3 test days demonstrated that TAP exhibited the highest inhibition of bacterial growth, followed by ACP which is not statistically significant (P = 1.00).

Considering the limitations of this in vitro study, the findings suggest that ACP could be an effective alternative intracanal medicament to TAP for endodontic therapy.

During endodontic treatment, the smear layer can reduce disinfectant efficacy. The aim of this study was to evaluate the antimicrobial efficacy of Er:YAG laser radiation and its combination with NaOCl and QMix against Enterococcus faecalis and Candidaalbicans and their comparison with conventional irrigation with only NaOCl and QMix.

Two hundred extracted single-rooted teeth after root canal preparation were divided into two groups and inoculated with E. faecalis and C.albicans. According to the treatment method, all samples were divided into five treatment groups: (1) Er:YAG laser, (2) NaOCl, (3) QMix, (4) Er:YAG laser plus NaOCl, and (5) Er:YAG laser plus QMix. After 24 hours of agar plate cultivation, cell viability was recorded with a flow cytometer.

All treatment modalities showed efficiency in the reduction of microbial cells. For laser treatment alone after exposure for 90 seconds, significantly fewer non-death cells were seen, compared to 30-second treatment. For both timings (30 and 90 seconds), irrigation with NaOCl or QMix after laser application resulted in significantly fewer vital cells of E. faecalis and C.albicans, compared with laser treatment alone (P < 0.001). The samples treated with only NaOCl showed a significantly higher percentage of vital E. faecalis and Candida albicans cells, compared to the samples treated with only QMix (P < 0.001).

Higher Er: YAG laser exposure time (90 seconds) after its combination with QMix and NaOCl improves the efficacy in the reduction of E. faecalis and C.albicans from the root canal, compared to 30-second laser exposure time and conventional irrigation methods with NaOCl and QMix.

 Root canal treatment failures are often attributed to incomplete removal of bacteria, particularly Enterococcus faecalis. While, chlorhexidine and sodium hypochlorite serve as conventional treatments. herbal medicine has been today considered as an alternative to synthetic medicine due to its safety. Therefore, the aim of the present study was to compare the antibactrial effect of Scrophularia Striata extract with chlorhexidine and sodium hypochlorite on Enterococcus Faecalis in the tooth root canal.

 In this study, sixty extracted teeth were examined. Following the infection of dental canals with Enterococcus faecalis, materials were tested in 3 groups: 1) chlorhexidine 2% (18 teeth), 2) sodium hypochlorite 2.5% (18 teeth), and 3) Scrophularia striata (at the concentration obtained from MIC, 20%; 18 teeth). Additionally, the positive control and negative control were included (3 teeth in each group). Samples were then cultured on bile esculin agar. After 72 hours, black colonies were eaxamined. Chi-squared test was used to analyze the results.

 Enterococcus faecalis bacteria grew in 6, 8, and 17 out of the 18 teeth within the sodium hypochlorite, chlorhexidine, and Scrophularia striata extract groups, respectively. Consequently, the bactericidal effects for sodium hypochlorite, chlorhexidine, and Scrophularia striata extract were 66.6%, 55.5%, and 5.55%, respectively.

The antibacterial effect of the Scrophularia striata extract was significantly lower than chlorhexidine and sodium hypochlorite on Enterococcus faecalis in dental canals viewed as a suitable replacement to the already in use synthetic therapeutic irrigants.

This study aimed to compare the colonization of Enterococcus faecalis (E. faecalis), Escherichia coli (E. coli), Streptococcus mutans (S. mutans) and Staphylococcus aureus (S. aureus) isolated from the oral cavity on different suture materials used in oral implantology.

Patients scheduled for implant surgery were included in this study. After flap approximation, the surgical site was sutured using silk, nylon, polyglactin 910 (Vicryl®) and triclosan-coated polyglactin 910 (Vicryl® Plus) sutures in a randomized order. Seven days after surgery, the sutures were removed and incubated in bile esculin agar (for E. faecalis), MacConkey agar (for E. coli), mitis salivarius agar (for S. mutans), and mannitol salt agar (for S. aureus) at 37°C for 24 h. The colonies were then counted. Data were analyzed using the Kruskal-Wallis and Mann-Whitney U tests.

Vicryl® sutures showed the highest accumulation of E. faecalis, followed by Vicryl® Plus, nylon, and silk. There was no significant difference between nylon and silk (P=0.5) or between Vicryl® and Vicryl® Plus (P=0.4). Vicryl® Plus sutures showed the highest accumulation of E. coli followed by Vicryl®, silk and nylon (P<0.01). Vicryl® sutures showed the highest accumulation of S. mutans, followed by Vicryl® Plus, silk, and nylon. Vicryl® Plus sutures showed the highest accumulation of S. aureus, followed by Vicryl®, nylon, and silk.

Nylon sutures showed the least microbial accumulation. Vicryl® and triclosan-coated Vicryl® Plus sutures had no advantage over the commonly used silk sutures in decreasing the number of bacteria.

The success of the endodontic treatment is closely associated with eliminating endodontic microbiota especially bacteria like Enterococcus Faecalis (E. Faecalis). Irrigation solutions are suggested for this purpose but there are contraries regarding irrigations and their concentrations. This study aimed to compare antibacterial efficacy of irrigations including 2.5% Sodium hypochlorite (NaOCl), 2% Chlorhexidine (CHX), and 1.5% Hydrogen peroxide (H2O2).  

Fifty deciduous human extracted teeth were divided into 3 groups of 15 teeth, 2.5% NaOCl, 2% CHX, 1.5% H2O2, and 5 teeth in the negative control group. Later, root canals were inoculated by E. Faecalis. After cleaning and shaping, we irrigated the root canals of the teeth in each group with NaOCl, CHX, and H2O2. Samples were obtained again and sent for microbiological evaluation. Wilcoxon signed-rank test, Paired sample T-test, and Kruskal–Wallis were used to analyze data.

All 3 groups showed significant bacterial reduction (p <0.05). NaOCl and CHX showed no significant difference (P=0.415). But the reduction of these 2 groups was higher than H2O2 (p

2.5% NaOCl and 2% Chlorhexidine showed considerable efficacy against E. Faecalis while 1.5% Hydrogen peroxide was not able to eradicate all of E. Faecalis colonies. Hence, NaOCl and CHX solutions can be used for decontamination of infected root canals

Due to the complex micro-anatomy of the root canal system, mechanical instrumentation leaves significant portions of the root canal walls untouched; therefore, complete elimination of bacteria from the root canal by cleaning with instrumentation alone is unlikely. It has long been postulated but not demonstrated, that any pulp tissue left in the root canals can serve as bacterial/fungal/viral (microorganism nutrients) nutrients. Furthermore, tissue remnants also impede the antimicrobial effects of root canal irrigants and medicaments and prevent intimate adaptation of the root canal filling to the dentin. Therefore, specific irrigation/disinfection procedures are necessary to remove tissue from the root canals and to kill microorganisms, respectively. The purpose of this paper was to review different aspects of a promising root canal irrigant; QMix. This is a relatively new root canal irrigant composed of traditional materials like chlorhexidine (CHX), ethylele diamine tetraacetic acid (EDTA), saline and a detergent. QMix is antibacterial, antifungal and has antibiofilm activities, it displays substantivity, smear layer removing ability; moreover, its effect on dentin and retention of fiber posts etc. has been reviewed. There have been strong reports that show the chemical design of QMix prevents precipitation of CHX when together with EDTA and mixing with sodium hypochlorite does not produce the orange-brown precipitate. Furthermore, the smear layer removal ability of QMix is comparable to that of 17% EDTA and the antibacterial activity of QMix was greater than 1% and 2% sodium hypochlorite (NaOCl) and 2% CHX.

 Enterococci are one of the opportunistic pathogenic microorganisms that can cause significant problems for human and animal health. Enterococcus faecium seems to be more resistant to antibiotics than E. faecalis. It is thought that pathogenic E. faecium can develop antibiotic resistance very quickly, and the ability to transfer this feature is considered to be an important health risk.

 This study aimed to determine the prevalence, biotypes, and in vitro antimicrobial susceptibility of E. faecalis and E. faecium strains isolated from 267 routine urine and stool samples that were brought to the microbiology laboratory of Regional Training and Research Hospital of Van, with permission of the patients.

 In the present study, enterococci using species-specific primers to examine E. faecalis and E. faecium multiplex PCR technique was applied. Biotyping of the isolates was used to identify them as E. faecalis and E. faecium by molecular techniques, and antibiotic susceptibility of all samples was examined, as well.

 The isolates were identified by multiplex PCR using species-specific primers for E. faecalis and E. faecium. Biotyping based on 13 biochemical tests showed that 72.5%, 12.5%, and 15% of E. faecalis strains were of biotypes I, II, and III, respectively, whereas E. faecium strains could be divided into biotype I (10%), biotype II (12.5%), biotype III (27.5%), and biotype IV (50%). Additionally, all E. faecalis strains were found to be susceptible to penicillin G and imipenem. On the other hand, 95% of the E. faecalis strains were found to be resistant to clindamycin, 77.5% to tetracycline and trimethoprim/sulfamethoxazole, 42.5% to erythromycin, 32.5% to gentamicin, and 17.5% to ciprofloxacin. Of E. faecium strains, 37.5% were found to be resistant to clindamycin, 32.5% to penicillin G, 27.5% to erythromycin and imipenem, 20% to ciprofloxacin, 17.5% to tetracycline and trimethoprim/sulfamethoxazole, 15% to gentamicin, and 5% to vancomycin.

 In conclusion, the identification of E. faecalis and E. faecium strains by PCR is reliable and faster than biochemical tests. Additionally, the results of antimicrobial susceptibility tests may provide important contributions to the clinical approach.

Because of complexity in root canals, irrigating solutions are needed in addition to mechanical instrumentation for thorough cleansing of the root canal system. This in-vitro study was designed to determine the inhibitory effect of arginine, protamine, and aqueous extracts of green tea and aloe vera against Enterococcus faecalis (E. faecalis), which causes endodontic failure. In this experimental study, aqueous extracts of green tea and aloe vera and protamine at a concentration of 400 mg/ml and arginine at a concentra-tion of 160 mg/ml were used. E. faecalis was cultured on Mueller-Hinton broth, and minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) of the test materials against these microorganisms were determined using serial dilutions and according to the microdilution test. The positive control was 2.5% sodium hypochlorite (NaOCl). Aqueous extract of aloe vera has high antibacterial activity against E. faecalis (MIC=12.5 mg/ml and MBC=100 mg/ml), and protamine had the least effect (MIC=400 mg/ml and MBC>400 mg/ml) compared to other test materials. NaOCl, with MIC and MBC of 0.25 mg/ml against E. faecalis, showed higher antibacterial activity compared to other test materials. Among the tested materials, except for NaOCl as a positive control, aqueous extract of aloe vera showed better antibacterial properties against E. faecalis.

The aim of this ex vivo study was to check the antimicrobial efficacy of silver nanoparticles with and without different antimicrobials against Enterococcus faecalis and Candida albicans.
Two-hundred and fifty two freshly extracted single-rooted human teeth were contaminated with E. faecalis and C. albicans. The teeth were randomly divided into five experimental (n = 21) and one control group (n = 21). Each subgroup was then exposed to different antimicrobials, namely calcium hydroxide (Ca(OH)2) (Group 1), 2% chlorhexidine (CHX) (Group 2), silver nanoparticles (SNP) (Group 3), SNP with Ca(OH)2 (Group 4), SNP with 2% CHX (Group 5), and saline as control group (Group 6). Cultures were made from each group after 24 h, 7 days, and 14 days, and colony forming units were counted. The Kruskal–Wallis test was used to compare the study parameters among the groups at 24 h, 7 days, and 14 days.
Significant difference was found in the antimicrobial efficacy of different intracanal medicaments against E. faecalis and C. albicans after 24 h, 7 days, and 14 days. 2% CHX was found to be the most effective medicament at 24 h, 7 days, and 14 days against E. faecalis and C. albicans. Combination of SNP with 2% CHX and Ca(OH)2 and SNP alone ranked second in their antimicrobial efficacy against E. faecalis and C. albicans at 24 h, 7 days, and 14 days, respectively.
2% CHX was more effective as intracanal medicament against E. faecalis and C. albicans biofilm in both short as well as long-term duration, i.e., at 24 h, 7 days, and 14 days.

Background & Aims of the Study: The safe drinking water providing is one of the most crucial objections in these centenaries. Bacterial water contamination and high rate of morbidity and mortality is crucial health threat. Efficiency of potassium persulfat (KPS) associated solar disinfection as a novel water disinfection technology was evaluated in batch scale experiments, using Ent. faecalis (ATTCC 29212).
Material and This research is a descriptive and experimental study which done on Tehran city, Iran. Ent. faecalis (ATTCC 29212) was provided in standard form from reference laboratory. Desired bacterial density in water was prepared by Mc Farland method. Water specimens were exhibited with solar radiations from 10 a.m to 16 p.m of Tehran local time. All experiments were conducted into 1.5 L volume of Damavand bottled water. Non-injured bacteria cells were detected by plating onto Bile Esculin azide agar media. Turbid water samples were provided by spiking of sterile slurry. Contact time (1-6 h), turbidity (30-200 NTU), KPS concentration (0.1, 0.7, 1.5 and 2 mMol/l), Ent. faecalis density(1000 and 1500 cell/ml) and UV intensity were independent and disinfection efficiency was a dependent variable, respectively.
Intensity of UVA solar irradiation varied from 3770 to 6263.3 µW/Cm2, with the highest value was measured on 13.30 p.m. In single SODIS and 1 hour contact time, increasing of bacterial closeness from 1000 to 1500 cell/ml implied disinfection performance decreasing in which, the vital bacteria was 10 and 20 cell/ml, respectively; but beyond of this contact time, a complete disinfection was occurred. Disinfection of Ent. faecalis was achieved within 2 h with single solar irradiation but KPS associated solar disinfection with applied dosage of KPS provide completely disinfection in 1 h in which the process efficiency was not influenced by increasing of bacterial density and turbidity up to 200 NTU.
Association of KPS with SODIS enhancing water disinfection which can be used in remote area and emergency status.

Aim: Most endodontic sealers show antimicrobial activity before setting, but most of them also lose this ability after setting. Addition of an antibiotic may affect the properties of sealers such as sealing ability, setting time, and so on. The aim of this study was to assess whether the addition of antibiotics (amoxicillin, doxycycline, and clindamycin) improves the sealing ability of AH 26 sealer.
Seventy extracted human mandibular premolars were used. After cleaning and shaping the canals, the teeth were divided into six groups: group 1: gutta-percha and AH 26 sealer, group 2: gutta-percha and AH 26 sealer皌牳✥詷, group 3: gutta-percha and AH 26 sealer橪ㆉ좥阩, group 4: gutta-percha and AH 26 sealer牘ꝵꦲ爩, group 5: gutta-percha without sealer (positive control), and group 6: gutta-percha and AH 26 sealer (the root surfacewere covered with nail varnish) (negative control). A microbial leakage model was used to assess the sealing ability.
Group 2 had the greatest resistance against bacterial leakage. Furthermore, combining AH 26 sealer with amoxicillin and clindamycin increased mean leakage time compared to AH 26 sealer solely. However, the differences between groups 1 and 3 as well as between groups 1 and 4 were not statistically significant.
Incorporating antibiotics especially doxycycline into AH 26 sealer increases its resistance against bacterial leakage.

The enterococci are responsible for infections including bacteremia and endocarditis which are usually resistant to multiple antibiotics. This nosocomial agent probably harbors putative virulence factors which increases their capability to colonize hospitalized patients.
This study was aimed in order to find the frequency of various virulence factors in enterococci and their relationship with multidrug resistance (MDR).
The samples were collected from different hospital wards including; Intensive care unit (ICU), cardiac care unit (CCU), pediatrics department, internal wards, and transplantation. The isolates were detected by biochemical tests and in order to determine the antibiotic susceptibility pattern, disk diffusion agar (kirby-bauer) was accomplished. Then, MICs (Minimum inhibitory concentrations) of vancomycin were determined by E-test strips. For molecular examinations and detection of drug resistance genes, the simple polymerase chain reaction was used. The multiplex PCR was used in order to detect virulence factors.
Total of 85 isolates were obtained from one university teaching hospital in southeast of Iran. Approximately 95% of isolated which were from urine specimens and 34% of isolates were collected from pediatrics units at hospital. Tetracycline resistance (48%) has been observed with a high frequency and related to the tetM gene. Furthermore, eighteen isolates were recognized as MDR strains that carried vanA, aac (6)-Ie-aph (2)-Ia, ermB, and tetM genes. Among virulence factor genes, asa1 (69%) and gelE (55%) are more frequently observed in both species. In general, we found Enterococcus faecalis strains more prevalent. Also, E. faecium was related to antibiotic resistance genes in nosocomial infection.
The data was indicated a high prevalence of multiple antibiotics resistance genes with virulence determinants in enterococci and also considered resistant isolate in pediatrics unit. The current results can be recommended in order to change new strategies for antibiotic therapy, because this serious pathogen is important for treatment and eradication in hospitals. Furthermore, the biofilm formation was regulated and constructed by virulence determinants that could be a candidate for enterococcal treatment.

Simultaneous presence of various antibiotics and bacteria in hospital wastewaters creates a suitable environment, in which the bacteria, such as enterococci become resistant to the antibiotics. The aim of this study was to evaluate the performance of different units of the hospital wastewater treatment plant (HWTP) to remove Enterococcus spp and Vancomycin-resistant Enterococcus (VRE). The study was performed on the 27 samples collected from HWTP in Hamedan, Iran during December 2014 to August 2015. Enterococcus spp and VRE were identified by biochemical tests and then the isolates were confirmed by PCR. Finally, the antibiotic susceptibility test was performed using disk diffusion methods. Of the 27 samples examined, 315 a total of enterococcal isolates were obtained. Of the 315 isolates of enterococci investigated, 162 (51.42%) were identified as E. faecium, 87 (27.61%) as E. hirae, 35 (11.11%) as E. faecalis, 11 (3.5%) as E. gallinarum, 7 (2.22%) as E. casseliflavus, 4 (1.26%) E. avium, and 9 (2.85%) isolates VR E. faecium.The results of antibiotic susceptibility testing showed that of the total 315 isolates, 146 (46.34%) were resistance to tetracycline, 9 (2.85%) were resistance to vancomycin and Teicoplanin. Lower antibiotic resistance was seen with Nitrofurantoin 2 (1.26%). This study indicates a high prevalence of multidrug resistance among E. faecium isolated from HWTP, thus, it could be considered as a threat to the health and safety of wastewater workers and even public health.

The aim of this study was to evaluate and compare the in vitro biofi lm forming capacity of Enterococcus faecalis on Gutta-percha points disinfected with four disinfectants. A total of 50 Gutta-percha points used in this study were divided into four test groups based on disinfectant (5.25% sodium hypochlorite, 2% chlorhexidine gluconate, 20% neem, 13% benzalkonium chloride [BAK]), and one control group. The Gutta-percha points were initially treated with corresponding disinfectants followed by anaerobic incubation in Brain Heart Infusion broth suspended with human serum and E. faecalis strain for 14 days. After incubation, these Gutta-percha points were stained with Acridine Orange (Sigma – Aldrich Co., St. Louis, MO, USA) and 0.5 mm thick cross section samples were prepared. The biofi lm thickness of E. faecalis was analyzed quantitatively using a confocal scanning laser microscope. Results statistically analyzed using analysis of variance. P < 0.05 was considered to be signifi cant. Confocal scanning laser microscope showed reduced amount of E. faecalis biofi lm on Guttapercha points treated with BAK and sodium hypochlorite. Post-hoc (least square differences) test revealed that there is no statistically signifi cant difference between BAK and sodium hypochlorite groups (P > 0.05). This study illustrates that the Gutta-percha points disinfected with sodium hypochlorite and BAK showed minimal biofi lm growth on its surface.

Calcium hydroxide (CH) is one of the most common intracanal medications. Corticosteroids (CS) are used in endodontics because of their anti-inflammatory activity. This study aimed to evaluate the antimicrobial effect of CH+betamethasone and CH+saline against Enterococcus faecalis (E. faecalis) using agar diffusion test and measuring the microbial zone of inhibition (ZOI). Methods and Materials: Four plates containing Mueller-Hinton broth and E. faecalis culture media, were prepared. In each plate, 5 holes (5×3 mm) were created and a creamy mixture of CH+betamethasone was inserted into the holes (10 holes for each material). Two holes with ampicillin disks and two empty holes were used as negative and positive controls, respectively. Plates were incubated for 24 h and then the diameter of microbial ZOI was measured. The pH of each mixture was measured by pH meter. Data were analyzed using the Mann-Whitney U test. The mean diameter of ZOI for CH+betamethasone and CH+saline was 3.4 and 3 mm, respectively. The difference was not significant (P=0.143). The pH was 12.5 for CH+saline and 12.3 CH+betamethasone, respectively. The mixture of CH+betamethasone had good antimicrobial effects against E. faecalis. Further studies are needed to confirm the value of this mixture in clinical settings.

Context: Biocompatible polymers are potentially effective for dental infections as delivery carriers of disinfectants or antibiotics into the root canal system (RCS). This study aimed to review polymeric microspheres enabling a controlled release of endodontic medicaments..Evidence Acquisition: A literature search was carried out in the PubMed database (May 2013) using the following keywords: “poly lactic-co-glycolic acid or PLGA”, “polymer microplate”, “encapsulate”, “drug delivery”, “controlled release”, “antibiotic”, “gentamycin”, and “amoxicillin”. We intended to find articles on the application of polymer microparticles for delivery and release of drugs in dental infections or articles discussing factors affecting the properties of these materials.. Seventeen articles were found evaluating the controlled release of the drugs for dental purposes; out of them, in 5 in vitro studies, polymer microspheres had been produced for root canal disinfection. Seven articles had investigated the properties of polymer microspheres and the factors influencing drug release by them.. Drug-loaded polymer microspheres may be used successfully as delivery carriers for controlled release of antibiotics into the root canal system. The efficacy and success rate of this method must be tested in animal models and then clinical trials..

The purpose of this in vitro study was to compare the ability of triple antibiotic paste (TAP) to calcium hydroxide (CH) in disinfecting dentinal tubules. Sixty root blocks were obtained from extracted single-rooted human teeth. The root canals were enlarged with Gates-Glidden drills up to size 3 and were contaminated with Enterococcus. faecalis (E. faecalis), and then left for 21 days. The contaminated blocks were treated with saline (as negative control), CH or TAP. Dentin debris was obtained at the end of first and 7th days, using Gates-Glidden drills sizes 4 and 5 from two different depths of 100 and 200 µm. The vital bacterial load was assessed by counting the number of colony forming units (CFUs). The data was analyzed with the Kruskal-Wallis H and Dunn Post-Hoc tests. The Wilcoxon Signed Ranks test was used to check for differences in bacterial growth at both depths (P<0.05). In comparison with CH, the TAP significantly decreased the number of CFUs in both depths and time intervals (P<0.001), while the CH group showed a moderate antibacterial effect. TAP is more effective in disinfecting the canal against E. faecalis compared to CH.

Due to their antimicrobial and dental plaque control activity, mouthwashes lead to an improvement in oral health. Although chemical mouthwashes have demonstrated the greatest antimicrobial and anti-inflammatory effects, their usage has been limited because of their numerous side effects. This study was conducted in vivo to determine the antibacterial and antifungal effects of Persica herbal mouthwash containing Salvadore persica, mint, and yarrow in comparison with a placebo. In this experimental, single-blind study, 80 dentistry students, who were eager to participate in the study, were randomly allocated into two groups of forty. One group was given Persica while the other group received a placebo. They were asked to apply the mouthwash twice a day for four weeks. The participants were unaware of the mouthwash type. Saliva sampling was conducted in all cases before and after mouthwash application and the samples were dispatched to a laboratory for microbial culture (Sabouraud and Clark-Kenner media culture). After two weeks, the washout times in groups were swapped with each other and the sampling was conducted just like before. Finally, the data were analyzed using independent and paired t-test. P values of less than 0.05 were considered significant. The mean age of participants was 23.20 ± 4.14. Persica mouthwash significantly decreased the count of Candida albicans (1.43 ± 0.15 to 0.8 ± 0.35) (P < 0.001) and Enterococcus faecalis (0.93 ± 1.76 to 0.71 ± 2.10) (P = 0.008). The statistical tests revealed that applying Persica mouthwash would result in a significant decrease in the Candida albicans and Enterococcus faecalis count. Regarding the significant and desirable effect of Persica on Candida albicans and Enterococcus faecalis, and its herbal origin, its application could be suggested to reduce oral microbes and infections from fungi and enterococci.
