Although foods are considered enhancing factors for dental caries and periodontitis, laboratory researches indicate that several foods and beverages contain components endowed with antimicrobial and antiplaque activities. A low molecular mass (LMM) fraction of an aqueous mushroom extract has been found to exert these activities inin vitroexperiments against potential oral pathogens. We therefore conducted a clinical trial in which we tested an LMM fraction of shiitake mushroom extract formulated in a mouthrinse in 30 young volunteers, comparing the results with those obtained in two identical cohorts, one of which received water (placebo) and the other Listerine. Plaque index, gingival index and bacterial counts in plaque samples were determined in all volunteers over the 11 days of the clinical trial. Statistically significant differences (P<0.05) were obtained for the plaque index on day 12 in subjects treated with mushroom versus placebo, while for the gingival index significant differences were found for both mushroom versus placebo and mushroom versus Listerine. Decreases in total bacterial counts and in counts of specific oral pathogens were observed for both mushroom extract and Listerine in comparison with placebo. The data suggest that a mushroom extract may prove beneficial in controlling dental caries and/or gingivitis/periodontitis.

Introduction: The purpose of this study was to evaluate and compare the effects of composition of aloe vera-green tea, matrica, and chlorhexidine on gingival inflammatory indices and dental stain index. Materials & Methods: In this double-blinded placebo-controlled clinical trial, anti-inflammatory, anti-plaque formation, and dental staining effects of two herbal mouthwashes, including aloe vera-green tea and matrica in comparison with chlorhexidine in 60 patients with plaque induced gingivitis referring to Isfahan University of Medical Sciences, School of Dentistry were evaluated. The indices evaluated in this study were plaque index (Silness and Loe), gingival index (Loe and Silness), bleeding on probing index (Ainamo and Bay) and dental stain index (Lobene stain index). They were evaluated on the first day of using mouthwashes and two weeks later. The obtained data were analyzed using SPSS software version 22. One-way ANOVA, Tukey post hoc, and paired t and Chi-square tests (α=0.05) were used as appropriate. Results: There was no significant difference between the four groups in terms of the mean values of plaque index, gingival index, BOP index, and stain index before the application of mouthwash. However, after mouthwash application, the mean values of indices were significantly different between the four groups. Aloe vera-green tea and chlorhexidine mouthwashes reduced plaque index, gingival index, and bleeding on probing index significantly and there was no significant difference between these two mouthwashes (P>0.05). The effect of matrica mouthwash on plaque index and gingival index was significantly lower than aloe vera-green tea and chlorhexidine (P<0.05). The mean reduction in BOP index was not significantly different between the aloe vera-green tea, chlorhexidine, and matrica groups. Regarding dental stain index, both herbal mouthwashes caused significantly lower dental stain in comparison with chlorhexidine (P<0.05). Conclusion: The results of the present study show that aloe vera-green tea mouthwash may be an effective mouthwash owing to its antiplaque and anti-inflammatory properties and may be an ideal substitute for chlorhexidine.

The increasing prevalence of dental caries is still as a major world health problem. Caries is the direct result of acid production by cariogenic oral pathogens, especially Streptococcus mutans. New and better antimicrobial agents active against cariogenic bacteria with minimal side effects on the oral tissues are much needed, especially natural agents derived directly from plants. Phytochemical studies have shown that the extracts from various parts of mangosteen or Garciniamangostana Linn tree contain varieties of secondary metabolites such as prenylated and oxygenated xanthones, many of which have been found in vitro to have antimicrobial properties against oral pathogens. Several studies which examined the eficacy of herbal for human health have shown that xanthones from mangosteen have remarkable biological activities such as antioxidant, antimicrobial, anticancer etc, and had no cytotoxic effects on human gingival fibroblasts. Their results showed that among these xanthone derivatives obtain from pericarp extract of mangosteen, α-mangostin has the most potent antimicrobial activity against cariogenic Streptococcus mutans. It can be concluded that the strong antimicrobial activity of the pericarp extract of mangosteen is a good drug of choice that might be helpful in preventing the dental caries.

Back ground: Dental caries and periodontal disease were the most common andwidely spread diseases affecting children. The nutrition may be one of the factorsaffecting the severity of the oral diseases. The Aims of this study was theassessment of the following oral diseases (dental caries, gingivitis) in addition toassessment of oral hygiene among 4-5 years old children in Karbala city –Iraq.Furthermore, nutritional status was assessed in relation to oral diseases.Materials and methods: A sample of 658 children (350 males, 308 females) agedfour and five years old was selected randomly from the fourteenth kindergartensin Karbala city. Diagnosis and recording of dental caries was followed the criteriaof WHO 1987. Dental plaque was assessed using plaque index of Silness and Loe,1964. Gingival health condition was assessed using gingival index of Loe andSilness, 1963. The assessment of nutritional status was performed usinganthropometric measurement (height and weight) according to Body mass indexindicator with -2SD cutoff point.Results: Caries prevalence was found to be (83%) of the total sample the mean rankvalue of dmfs was higher among boys in comparison to girls with statistically nosignificant difference (P>0.05). The value of dmfs increased with age withstatistically highly significant difference (p<0.01).The mean rank values of dentalplaque and gingival indices for total boys were found to be higher than total girlswith statistically highly significant differences (P<0.01). Recording of this studydemonstrated that 100% of children had dental plaque and gingival inflammation.Positive highly significant correlations were recorded between dental caries withdental plaque and gingival indices. The prevalence of malnutrition described byBody mass index indicator was (3.2%). According to nutritional status indicatorBody mass index-for-age, it was found that the wasted children had higher valueof dmfs than well nourished children with statistically no significant differences(P>0.05). The plaque and gingival indices were higher among well nourishedchildren than among wasted children with statistically highly significantdifferences (P<0.01).The correlation coefficient between body mass index withdental caries, plaque index and gingival index were very weak and statistically notsignificant (p>0.05).Conclusions: High prevalence of dental caries and gingivitis was recorded indicatingthe need of public and preventive programs among kindergarten children.

To clinically evaluate & compare the efficacy of 4% Mangosteen Gel and 1% chlorhexidine digluconate gel in managing patients with chronic gingivitis. Materials and Methods: A total of 50 patients with an age group of 20-45 years diagnosed with generalized plaque-induced gingivitis were selected for this clinical trial once attaining their informed consent. A thorough case history was chronicled comprising plaque index (P.I.), gingival index (G.I.) and Sulcus bleeding index (SBI) at baseline; then full-mouth scaling and polishing (SAP) was performed by a solitary attuned examiner. Patients were then randomly assigned into two groups using a computer-generated random numbering sequence system. Patients in group A received 4% Mangosteen Gel, and group B received 1% chlorhexidine digluconate gel for home application. The post-treatment follow-up examination for P.I., G.I. and SBI changes were assessed after 14 days and 21 days and compared with baseline data. Results: In both the groups, the mean plaque index, gingival index and sulcus bleeding index scores were significantly decreased after the 14th and 21st day compared to baseline scores. There was no significant difference between the groups, but only in group B, there was a substantial difference in SBI scores observed on day 21. Conclusion: 4% Mangosteen Gel and 1% chlorhexidine digluconate gel were clinically effective when used as an adjunct to SAP in managing patients with gingivitis. Hence, 4% Mangosteen Gel can be considered an alternative to 1% chlorhexidine digluconate gel without any side effects in managing generalized plaque-induced gingivitis.

Original article Article History: Received: 23 April 2018 Revised: 20 July 2018 Accepted: 06 August 2018 * Corresponding author:Batool Sadeghi-NejadAbadan School of Medical Sciences, Abadan, Iran.Email: [email protected] Introduction One of the most common chronic oral infections in the world is dental caries [1]. Oral pathogenic microorganisms have been the cause of dental plaques, dental caries, as well as gingival and periodontal diseases [2]. Streptococcus mutans is one of the main opportunistic pathogens of dental caries, which is responsible for the formation of dental plaque and caries [3]. Other microorganisms associated with this oral condition include Escherichia coli, S. aureus [4], and Candida species. C. albicans is the most frequent yeast isolated from the oral cavities with poor oral hygiene [2]. The formulation ingredients of commercial toothpastes are mostly chemical substances, such as fluoride and whitening agents [2]. The literature contains evidence regarding the adverse effects of fluoride and bleaching agents (e.g., peroxide-based agents) used in the commercial toothpastes [5]. With this background in mind, the present study aimed to formulate a polyherbal toothpaste without any A B S T RA C TBackground and Purpose: Herbal toothpastes are more secure and efficacious and less poisonous due to containing natural chemicals as compared with the synthetic toothpastes. The present study aimed to formulate a polyherbal toothpaste using accessible medicinal plants in Iran and evaluate its efficiency in the protection of oral hygiene and prevention of dental caries. Materials and Methods: The developed toothpaste was made of the leaf extracts of Artemisia dracunculus, Satureja khuzestanica (Jamzad), and Myrtus communis (Linn), combined at four different dilutions, namely 1:4 (25%), 1:1 (50%), 3:4 (75%), and (100%), with sterile distilled water. The product was tested against five microorganisms, including Streptococcus mutans, Lactobaccilus caseie, S. sanguis, S. salivarius, and Candida albicans, using agar well diffusion method. Results: After 24 h of incubation, the maximum mean diameters of inhibition zone against L. caseie and C. albicans were obtained as 17-30 and 10-25 mm, respectively. Furthermore, the minimum mean diameter of inhibition zone against S. salivarious was estimated as 15-20 mm. Conclusion: The formulated toothpaste showed potent inhibitory activities against Gram-positive bacteria and C. albicans. Therefore, more studies are required to accurately investigate the efficacy of the formulated toothpaste. Keywords: Antibacterial, Antifungal, Oral pathogens, Polyherbal toothpaste, Yeast

Objectives: This study aimed to determine the minimum inhibitory concentration (MIC) of mouthwashes prepared from neem and mango extracts against Streptococcus mutans (S. mutans) in vitro. Their taste acceptability and effects on plaque index (PI), gingival index (GI) and salivary pH were also evaluated and compared with chlorhexidine (CHX) in children. Materials and Methods: Dry extracts of neem and mango twigs were prepared and their MIC against S. mutans was determined. The effective MIC was used to prepare mouthwashes from the two extracts. Three parallel groups of children (n=30) used either neem, mango or 0.2% CHX mouthwash for 21 days. The PI and GI were recorded at baseline and at 7 and 21 days. The salivary pH and taste acceptability were also assessed. Results: The MIC of both extracts was achieved at 25% concentration. There was a significant difference between the GI score of mango group compared with neem and CHX at the three time points (P<0.001). There was no significant difference between the neem and mango groups in PI (P=0.674). There was no significant difference among the three groups in salivary pH either (P=0.817). Intragroup comparison showed significant reductions in PI, GI and salivary pH in all the three groups after 21 days (P<0.001). Conclusion: Neem and mango mouthwashes can be used as effective alternatives to CHX in children.

Abstract Purpose Coronavirus disease 19 (COVID-19) has, to date, been diagnosed in over 130 million persons worldwide and is caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Several variants of concern have emerged including those in the United Kingdom, South Africa, and Brazil. SARS-CoV-2 can cause a dysregulated inflammatory response known as a cytokine storm, which can progress rapidly to acute respiratory distress syndrome (ARDS), multi-organ failure, and death. Suppressing these cytokine elevations may be key to improving outcomes. Remote ischemic conditioning (RIC) is a simple, non-invasive procedure whereby a blood pressure cuff is inflated and deflated on the upper arm for several cycles. “RIC in COVID-19” is a pilot, multi-center, randomized clinical trial, designed to ascertain whether RIC suppresses inflammatory cytokine production. Methods A minimum of 55 adult patients with diagnosed COVID-19, but not of critical status, will be enrolled from centers in the United Kingdom, Brazil, and South Africa. RIC will be administered daily for up to 15 days. The primary outcome is the level of inflammatory cytokines that are involved in the cytokine storm that can occur following SARS-CoV-2 infection. The secondary endpoint is the time between admission and until intensive care admission or death. The in vitro cytotoxicity of patient blood will also be assessed using primary human cardiac endothelial cells. Conclusions The results of this pilot study will provide initial evidence on the ability of RIC to suppress the production of inflammatory cytokines in the setting of COVID-19. Trial Registration NCT04699227, registered January 7th, 2021.

Abstract Background The rapid emergence and the high disease burden of the novel coronavirus SARS-CoV-2 have created a medical need for readily available drugs that can decrease viral replication or blunt the hyperinflammatory state leading to severe COVID-19 disease. Azithromycin is a macrolide antibiotic, known for its immunomodulatory properties. It has shown antiviral effect specifically against SARS-CoV-2 in vitro and acts on cytokine signaling pathways that have been implicated in COVID-19. Methods DAWn-AZITHRO is a randomized, open-label, phase 2 proof-of-concept, multicenter clinical trial, evaluating the safety and efficacy of azithromycin for treating hospitalized patients with COVID-19. It is part of a series of trials testing promising interventions for COVID-19, running in parallel and grouped under the name DAWn-studies. Patients hospitalized on dedicated COVID wards are eligible for study inclusion when they are symptomatic (i.e., clinical or radiological signs) and have been diagnosed with COVID-19 within the last 72 h through PCR (nasopharyngeal swab or bronchoalveolar lavage) or chest CT scan showing typical features of COVID-19 and without alternate diagnosis. Patients are block-randomized (9 patients) with a 2:1 allocation to receive azithromycin plus standard of care versus standard of care alone. Standard of care is mostly supportive, but may comprise hydroxychloroquine, up to the treating physician’s discretion and depending on local policy and national health regulations. The treatment group receives azithromycin qd 500 mg during the first 5 consecutive days after inclusion. The trial will include 284 patients and recruits from 15 centers across Belgium. The primary outcome is time from admission (day 0) to life discharge or to sustained clinical improvement, defined as an improvement of two points on the WHO 7-category ordinal scale sustained for at least 3 days. Discussion The trial investigates the urgent and still unmet global need for drugs that may impact the disease course of COVID-19. It will either provide support or else justify the discouragement of the current widespread, uncontrolled use of azithromycin in patients with COVID-19. The analogous design of other parallel trials of the DAWN consortium will amplify the chance of identifying successful treatment strategies and allow comparison of treatment effects within an identical clinical context.
