RESUMEN
OBJECTIVE: The study aimed to investigate the potential beneficial role of hydrogen peroxide (H2O2) and hyaluronic acid (HA) combination formulation in socket healing after third molar surgery. Biomaterials, including mouthwash formulations, were hypothesized to contribute to improved socket healing and reduced post-operative complications. PATIENTS AND METHODS: A triple-blinded parallel randomized controlled clinical trial was conducted at a single-center dental hospital in Milan, Italy. The trial included 114 patients who underwent extraction of impacted, partially erupted, and completely erupted third molars. Patients were randomly assigned to three parallel groups: Group 1 (H2O2 and HA), Group 2 (placebo), and Group 3 (0.2% chlorhexidine). The trial was registered at ClinicalTrial.gov (registration number NCT04438434). The main outcome measures included various parameters related to socket healing, such as pain, inflammation, swelling, plaque index, bleeding index, granulation tissue, suppuration, re-epithelialization, bleeding upon palpation, odor, and taste alteration. Patients were followed up for 7 days. RESULTS: All 114 enrolled patients completed the study, with no dropouts or loss to follow-up. The mean age of patients in the three groups differed (H2O2 and HA: 30.9±14.9; placebo: 27.6±13.1; 0.2% chlorhexidine: 23.05±10.16). Significant reductions (p<0.001) in visual analog scale (VAS) pain levels and other outcome measures were observed in the H2O2 and HA group compared to the placebo group. These findings suggest a positive effect of the H2O2 and HA combination on socket healing after the third molar surgery. CONCLUSIONS: The study concludes that the combination of hydrogen peroxide and hyaluronic acid can be considered a potential mouthwash with beneficial effects on socket healing following third molar surgery. However, additional clinical trials are recommended to validate its effectiveness further and provide additional evidence supporting its use in clinical settings. CLINICALTRIAL: gov: NCT04438434.

OBJECTIVES: Helicobacter pylori gastric infection strongly correlates with gastric diseases such as chronic gastritis, functional dyspepsia, and complications such as peptic ulcers and gastric cancer. In developing countries, systemic therapies are not usually successful due to elevated antibiotic resistance. Additionally, oral H. pylori infection and periodontal disease correlate with gastric treatment failures. This study aimed to explore the effect of an integral therapy, comprising oral hygiene and concomitant systemic treatment, to increase the eradication of gastric infection and recurrences. MATERIALS AND METHODS: A prospective, randomized, four-arm, parallel-group, open-label clinical trial was conducted to investigate the efficacy of integral therapy to eradicate gastric H. pylori infection and avoid recurrences in double-positive (real-time PCR oral and gastric infection) patients. Oral hygiene involved mouthwash with neutral electrolyzed water (NEW), with or without periodontal treatment. One hundred patients were equally distributed into four groups: NS, NS-PT, NEW, and NEW-PT. All patients had concomitant systemic therapy and additionally, the following oral treatments: mouthwash with normal saline (NS), periodontal treatment and mouthwash with normal saline (NS-PT), mouthwash with NEW (NEW), and periodontal treatment and mouthwash with NEW (NEW-PT). Gastric and oral infection and symptoms were evaluated one and four months after treatments. RESULTS: Integral therapy with NEW-PT increased gastric eradication rates compared with NS or NS-PT (84%-96% vs. 20%-56%; p < 0.001). Even more, a protective effect of 81.2% (RR = 0.1877; 95% CI: 0.0658-0.5355; p = 0.0018) against recurrences and 76.6% (RR = 0.2439; 95% CI: 0.1380-0.4310; p < 0.001) against treatment failure (eradication of infection and associated symptoms) was observed in patients from the NEW and NEW-PT groups. CONCLUSIONS: Implementation of oral hygiene and systemic treatment can increase the eradication of gastric infection, associated symptoms, and recurrences. NEW is recommended as an antiseptic mouthwash due to its efficacy and short- and long-term safety.

Asthma is an airways inflammatory disease and the most common chronic disease of childhood, which causes most hospital visits and placing a heavy financial burden on families and communities. Interleukins 4, 5 and 13, play a central role in the pathogenesis of asthma. Given the importance of oral hygiene in asthmatic patients and IL-4 and 5 are involved in the inflammatory process of periodontitis, the effect of chlorhexidine as mouthwash on asthma attacks in children on serum cytokines is necessary. In this study, 375 children with asthma were divided into two groups using or non-using chlorhexidine. Blood samples were taken and cytokines were measured by ELISA. From 375 patients, 17 patients were excluded. In this study, 171 males and 187 females participated and there were 180 patients in asthma group and 178 patients in asthma/Chlorhexidine group. The levels of IL-4, IL-5 and IL-13 had no significant difference (p > 0.05) between Asthma and Asthma/Chlorhexidine groups. Using chlorhexidine as mouthwash in children with asthma had no effect on the type 2 cytokines and may not trigger an asthma attack via allergo-inflammatory mechanism.

Introduction. ListerineÒ is a bactericidal mouthwash widely used to prevent oral health problems such as dental plaque and gingivitis. However, whether it promotes or undermines a healthy oral microbiome is unclear.Hypothesis/Gap Statement. We hypothesized that the daily use of Listerine Cool Mint would have a significant impact on the oropharyngeal microbiome.Aim. We aimed to assess if daily usage of Listerine Cool Mint influenced the composition of the pharyngeal microbiome.Methodology. The current microbiome substudy is part of the Preventing Resistance in Gonorrhoea trial. This was a double-blind single-centre, crossover, randomized controlled trial of antibacterial versus placebo mouthwash to reduce the incidence of gonorrhoea/chlamydia/syphilis in men who have sex with men (MSM) taking HIV pre-exposure prophylaxis (PrEP). Fifty-nine MSM taking HIV PrEP were enrolled. In this crossover trial, participants received 3 months of daily Listerine followed by 3 months of placebo mouthwash or vice versa. Oropharyngeal swabs were taken at baseline and after 3 months use of each mouthwash. DNA was extracted for shotgun metagenomic sequencing (Illumina Inc.). Non-host reads were taxonomically classified with MiniKraken and Bracken. The alpha and beta diversity indices were compared between baseline and after each mouthwash use. Differentially abundant bacterial taxa were identified using ANOVA-like differential expression analysis.Results. Streptococcus was the most abundant genus in most samples (n = 103, 61.7â%) with a median relative abundance of 31.5% (IQR 20.6-44.8), followed by Prevotella [13.5% (IQR 4.8-22.6)] and Veillonella [10.0% (IQR 4.0-16.8)]. Compared to baseline, the composition of the oral microbiome at the genus level (beta diversity) was significantly different after 3 months of Listerine (P = 0.006, pseudo-F = 2.29) or placebo (P = 0.003, pseudo-F = 2.49, permutational multivariate analysis of variance) use. Fusobacterium nucleatum and Streptococcus anginosus were significantly more abundant after Listerine use compared to baseline.Conclusion. Listerine use was associated with an increased abundance of common oral opportunistic bacteria previously reported to be enriched in periodontal diseases, oesophageal and colorectal cancer, and systemic diseases. These findings suggest that the regular use of Listerine mouthwash should be carefully considered.

(1) Background: This study compared the effects of mouth rinsing with a carbohydrate trial (CMR) and a placebo trial (PL) on concentric and eccentric contraction strength in multi-joint resistance exercise performance. (2) Methods: Twenty healthy adult men (age: 22.4 ± 3.7 years, body mass index: 26 ± 3.8, peak power: 378.3 ± 138.7 W) were recruited in this study. Participants were employed in a double-blind, randomized crossover design to divide participants into carbohydrate mouth rinsing trial (CMR) and placebo trial (PL). After warming up, participants used 6.6% maltodextrin (CMR) or mineral water (PL) to rinse their mouth for 20 s. Next, the participants underwent tests of maximum inertial Romanian deadlift resistance exercise comprising five sets of six reps, with 3 min rests between sets. After deducting the first repetition of each set, the mean values from the five sets were analyzed. (3) Results: The concentric peak power of the CMR trial was significantly higher than that of the PL trial (p = 0.001, Cohen's d = 0.46), the eccentric peak power of the CMR trial was significantly higher than that of the PL trial (p = 0.008, Cohen's d = 0.56), and the total work of the CMR trial was significantly higher than that of PL trial (p = 0.002, Cohen's d = 0.51). (4) Conclusions: These findings demonstrate that mouth rinsing with carbohydrates before exercise can improve concentric and eccentric contraction strength in multi-joint resistance exercise performance.

Introduction: Periodontitis is a pandemic, with about 14 percent of people worldwide already suffering from severe periodontitis. Early intervention in the disease could probably reduce its progression and eliminate the need for the extraction of affected teeth. Quercetin is a probable candidate as it has exemplary anti-inflammatory properties. The presence of phenolic hydroxyl groups in them greatly contributes to their antioxidant and anti-inflammatory activities. Objectives: The study introduces the formulation of Quercetin mouthwash and assesses its anti-inflammatory properties in comparison to Diclofenac sodium. Methods: Quercetin mouthwash was prepared using a commercially procured bioactive agent. One standard nonsteroidal anti-inflammatory drug, Diclofenac was used as a reference drug. The percentage inhibition of protein denaturation was calculated and its anti-inflammatory properties were evaluated through Bovine Serum Albumin Assay and Egg Albumin Assay. Results: Quercetin mouthwash showed parallel anti-inflammatory properties and showed a proportionate increase in anti-inflammatory properties with the increase in the concentration of the mouthwash. Comparable inhibition of protein denaturation at 10µl and 50µl concentrations with a proportionate variation of 1 percent (p>0.05) to the control in Egg Albumin Assay and 47 percent and 83 percent denaturation at 10µl and 50µl of Bovine Serum Albumin Assay were observed. Conclusion: Quercetin mouthwash has shown significant anti-inflammatory activity and hence is considered a potent anti-inflammatory agent comparable to Diclofenac sodium. It is found to be a suitable agent as an oral formulation for reducing the progression of inflammatory conditions(AU)
Introducción: La periodontitis es una pandemia, ya que alrededor del 14 por ciento de las personas en todo el mundo padecen periodontitis grave. Una intervención precoz en la enfermedad podría, probablemente, reducir su progresión y eliminar la necesidad de extraer los dientes afectados. La quercetina es un candidato probable, ya que tiene propiedades antiinflamatorias ejemplares. Su presencia de grupos hidroxilos fenólicos contribuye en gran medida a sus actividades antioxidantes y antiinflamatorias. Objetivos: El estudio presenta la formulación del colutorio de quercetina y evalúa sus propiedades antiinflamatorias en comparación con el diclofenaco sódico. Métodos: Se preparó un colutorio de quercetina, utilizando un agente bioactivo obtenido comercialmente. Se utilizó como fármaco de referencia un antiinflamatorio no esteroideo estándar, el diclofenaco. Se calculó el porcentaje de inhibición de la desnaturalización de proteínas y se evaluaron sus propiedades antiinflamatorias mediante ensayo con albúmina de suero bovino y con albúmina de huevo. Resultados: El colutorio de quercetina mostró propiedades antiinflamatorias paralelas y mostró un aumento proporcional de las propiedades antiinflamatorias con el aumento de la concentración del colutorio. Se observó una inhibición comparable de la desnaturalización de proteínas a concentraciones de 10µl y 50µl con una variación proporcional del 1 por ciento (p > 0,05), respecto al control en el ensayo de albúmina de huevo y una desnaturalización del 47 por ciento y 83 por ciento a 10µl y 50µl del ensayo de albúmina de suero bovino. Conclusiones: El enjuague bucal de quercetina ha mostrado una actividad antiinflamatoria significativa, por lo que se considera un potente agente antiinflamatorio comparable al diclofenaco sódico. Se considera un agente adecuado como formulación oral para reducir la progresión de las afecciones inflamatorias(AU)

BACKGROUND: The separators are a preliminary step for band insertion, but there is a potential risk of bacteraemia during their placement, particularly in susceptible patients. The objective of the study is to determine the effect of separators on the bacterial count in gingival crevicular fluid (GCF) and to assess the efficacy of chlorhexidine mouth rinse and saline irrigation in the reduction of the bacterial count. METHODS: This randomized controlled trial was conducted on 51 participants who were divided into three equal g roups randomly (brushing only/control, saline irrigation, and 2% chlorhexidine mouthwash rinse). The inclusion criteria were age between 18-25 years, good oral hygiene, gingival and plaque index <1, no previous orthodontic treatment, and healthy individuals. The bacterial count was obtained from GCF samples after two hours, on the third day, and on the seventh day. Kruskal Wallis test was used to compare the bacterial count among the three groups, and post hoc analysis was done using Dunn's test. Friedman test was applied to see the difference at three-time points in each group. RESULTS: In both saline and chlorhexidine groups the mean bacterial count decreased significantly from baseline to 3rd day and 7th day after separator placement (p<0.001). For the third day, a significant difference was found in control versus saline and control versus chlorhexidine. No significant difference was found between saline and chlorhexidine on the third day. Similar results were found on the 7 thday. For controls, the bacterial count increased with time and for both saline and chlorhexidine groups the bacterial count decreased. The highest decrease in the bacterial count was found for the chlorhexidine group. CONCLUSIONS: After the placement of separators, there was an increase in the bacterial count in GCF. Notably, chlorhexidine was found to be more effective than saline irrigation in reducing the bacterial count.

Introducción: Los enjuagues bucales contribuyen a la inhibición de la formación de la placa bacteriana y, por tanto, pueden ayudar a mantener el pH salival cercano a neutro. Objetivo: Identificar cambios en el pH salival de pacientes portadores de aparatología ortodóncica fija, después del enjuague con una solución de Stevia rebaudiana Bertoni y un enjuague comercial de aceites esenciales. Métodos: Se realizó un experimento clínico con un diseño factorial mixto en pacientes portadores de aparatología ortodóncica fija. Una vez firmado el consentimiento informado, treinta y dos pacientes fueron asignados aleatoriamente a uno de 2 grupos: la solución de S. rebaudiana B. al 2 por ciento o un enjuague comercial de aceites esenciales. Se utilizaron 15 ml de enjuague durante 60 s en todos los pacientes. El pH salival fue medido por dos observadores independientes calibrados, utilizando papel medidor de pH antes del enjuague (medición basal) y después del enjuague, a los 5 y 20 min. Los datos fueron analizados mediante el ANOVA mixto. Resultados: Se encontró una interacción estadísticamente significativa entre el tipo de tratamiento y el momento de medición del pH. Los pH medio de los grupos S. rebaudiana y aceites esenciales fueron respectivamente en la medición basal: 6,61 y 6,52 (p = 0,72); a los 5 min: 7,61 y 7,77 (p = 0,40); y a los 20 min: 7,72 y 6,82 (p < 0,001). Conclusiones: Ambos enjuagues tenían el efecto de aumentar el pH salival a niveles alcalinos a los 5 min, pero solo el enjuague de S. rebaudiana B. al 2 por ciento mantuvo el pH básico a los 20 min(AU)
Introduction: Mouthwashes contribute to the inhibition of bacterial plaque formation and, therefore, may help to maintain salivary pH close to neutral. Objective: To identify changes in salivary pH in patients with fixed orthodontics after using a Stevia rebaudiana Bertoni solution and a commercial essential oil mouthwash. Methods: A clinical experiment with a mixed factorial design was carried out in patients with fixed orthodontic appliances. Once informed consent was signed, thirty-two patients were randomly assigned to one of 2 groups: 2 % S. rebaudiana B. solution or a commercial essential oil mouthwash. Fifteen ml of mouthwash was used for 60 s in all patients. Salivary pH was measured by two independent calibrated observers using pH-measuring paper before rinsing (basal measurement) and after rinsing, after 5 and 20 min. The data were analyzed by mixed ANOVA. Results: A statistically significant interaction was found between the type of treatment and the time of pH measurement. The medium pH of the S. rebaudiana and essential oil groups were respectively as per basal measurement: 6.61 and 6.52 (p = 0.72); after 5 min: 7.61 and 7.77 (p = 0.40); and after 20 min: 7.72 and 6.82 (p < 0.001). Conclusions: Both mouthwashes had the effect of increasing salivary pH to alkaline levels after 5 min, but only the 2 percent S. rebaudiana B. mouthwash maintained the basic pH after 20 min(AU)

Ventilator-associated pneumonia (VAP) is related with high mortality, duration of mechanical ventilation and costs. Recent studies have questioned the safety and effectiveness of oral chlorhexidine to prevent VAP. We sought to verify whether the adverse effects of this substance outweigh its benefits. We searched several databases and selected studies that investigated the use of oral chlorhexidine and its impact on mortality. No association between oral chlorhexidine and lower VAP rates was found on meta-analyses of double-blind randomized trials, however significant increase in mortality was reported. It is speculated that chlorhexidine can cause damage to several organic sectors and cytotoxicity. Although it still can be beneficial in specific settings, robust evidence to recommend its routine application for all mechanically ventilated patients is lacking; therefore, given the possibility of harm, it would be better to follow the principle of non-maleficence until more studies becomes available.

ETHNOPHARMACOLOGICAL RELEVANCE: In modern medicine, some traditional remedies are introduced to be effective in treatment. Accordingly, the henna plant (Lawsonia inermis L.) is studied more than before. Previous studies have shown many medical properties for henna, such as anti-inflammatory and anti-fungal properties. AIM OF THE STUDY: Oral lichen planus (OLP) is a common mucocutaneous disease with chronic immunomodulatory disruptions. Topical corticosteroids are the first line of OLP treatment. Previous studies have suggested different adjunctive therapies for preventing the side effects of corticosteroids overuse. This study aimed to compare the effects of henna and chlorhexidine mouthwashes as adjunctive therapy. MATERIALS AND METHODS: This parallel-group, double-blind, randomized controlled study was conducted on forty OLP patients. Luteolin content was determined in Henna mouthwash composed of 2% aqueous extract of henna, 2% ethanol, 10% glycerol, and 0.1% methylparaben distilled water. Henna or chlorhexidine mouthwashes were prescribed twice daily as an adjuvant to the topical corticosteroid treatment. Visual analog scale (VAS) index and Thongprasom rating were used to measure pain intensity and clinical signs of patients at days 0,7, and 14. The collected data were analyzed using SPSS software (version 26.0; SPSS). Ordinal logistic regression was used to investigate the effect of independent variables on Thongprasom and VAS scores. RESULTS: In this clinical trial, 82.6% of the participants were women. There was no difference between the two study groups in terms of VAS scores (p = 0.404) and clinical features (p = 0.305) in the second follow-up visit. All drug regimens caused clinical signs and symptoms relief. CONCLUSIONS: There was no significant difference between the groups receiving topical corticosteroid supplementation, neither henna mouthwash nor chlorhexidine mouthwash. The therapeutic effects of henna mouthwash in the main or adjuvant treatment of OLP need more evaluation in future research. Henna mouthwash can be a good alternative to chlorhexidine mouthwash if no side effects are reported.

The current study compared mouth swills containing carbohydrate (CHO), menthol (MEN) or a combination (BOTH) on 40 km cycling time trial (TT) performance in the heat (32 °C, 40% humidity, 1000 W radiant load) and investigates associated physiological (rectal temperature (Trec), heart rate (HR)) and subjective measures (thermal comfort (TC), thermal sensation (TS), thirst, oral cooling (OC) and RPE (legs and lungs)). Eight recreationally trained male cyclists (32 ± 9 y; height: 180.9 ± 7.0 cm; weight: 76.3 ± 10.4 kg) completed familiarisation and three experimental trials, swilling either MEN, CHO or BOTH at 10 km intervals (5, 15, 25, 35 km). The 40 km TT performance did not differ significantly between conditions (F2,14 = 0.343; p = 0.715; η2 = 0.047), yet post-hoc testing indicated small differences between MEN and CHO (d = 0.225) and MEN and BOTH (d = 0.275). Subjective measures (TC, TS, RPE) were significantly affected by distance but showed no significant differences between solutions. Within-subject analysis found significant interactions between solution and location upon OC intensity (F28,196 = 2.577; p < 0.001; η2 = 0.269). While solutions containing MEN resulted in a greater sensation of OC, solutions containing CHO experienced small improvements in TT performance. Stimulation of central CHO pathways during self-paced cycling TT in the heat may be of more importance to performance than perceptual cooling interventions. However, no detrimental effects are seen when interventions are combined.

INTRODUCTION: Oral mucositis is inflammation of the mucosa of the mouth which ranges from redness to severe ulceration. It results from the local effects of radiation to the oral mucosa. OBJECTIVES: The study is cumulative analysis of two studies (one comparative and the other open labeled) evaluated in individuals with oral mucositis during cancer radiotherapy and/or chemotherapy for the safety and efficacy of Oro-T mouthwash in a comparative design with normal saline. METHODOLOGY: Both the studies were similar with respect to clinical and laboratory parameters for analysis. The participants were advised to use 10 ml of Oro-T for 1 min 4 times daily for 6 weeks starting from day 1 of standard care. Patients were followed up, and the results were assessed from baseline on visit days: At entry and at the end of every week for 6 weeks. Clinical assessment of oral condition was done objectively (by the investigator) and also subjectively. Clinical symptoms such as sore throat, number of ulcer, burning sensation, pain, difficulty in chewing, difficulty in drinking, and mucositis grading along with Patient Reported Outcome Measures Scale were evaluated at each interval. Data was available for 40 subjects in Oro-T and 15 subjects in NS groups respectively. RESULTS AND CONCLUSION: The significant positive outcome was reported both subjectively and objectively in Oro-T group as compared to NS group with the delay in the onset of symptoms and less severe manifestation of oral mucositis with an improvement in quality of life. No adverse effects were reported that prompted discontinuation of study medication. Overall compliance to study medication was good.

OBJECTIVE: Face masks help contain the aerosol-mediated transmission of infectious viral particles released from individuals via cough and sneezes. However, the prolonged use of face masks has raised concerns regarding oral hygiene. Here, we present a mouthwash formulation based on α-cyclodextrin and hydroxytyrosol that can maintain healthy oral microbiota. MATERIALS AND METHODS: We isolated and cultured Candida albicans, Staphylococcus aureus, and a mix of Streptococcus sp., Staphylococcus sp. and Neisseria sp. from oral and throat swabs. The microorganisms were cultured in a standard medium with or without the mouthwash. To evaluate the effect of the mouthwash on the oral microbiota, the DNA from the saliva of 3 volunteers that used the mouthwash was extracted. Then, the DNA was amplified using primer pairs specific for bacterial and fungal DNA. Twelve further volunteers were offered to use the mouthwash and a questionnaire was submitted to them to assess the possible beneficial effects of mouthwash on halitosis and other oral disturbances. RESULTS: The bacteria and fungi cultured in media containing the mouthwash showed a growth reduction ranging from 20 to 80%. The PCR amplification of fungal and bacterial DNA extracted from volunteers that used the mouthwash showed a reduction of both bacteria and fungi. Volunteers that used the mouthwash reported a tendency towards a reduction of halitosis, gingival and mouth inflammation, and dry mouth. CONCLUSIONS: The use of a mouthwash containing α-cyclodextrin and hydroxytyrosol is not aggressive against oral mucosa; it is safe and effective to reduce the bacterial and fungal load due to the continuous use of face masks.

INTRODUCCIÓN: El virus SARS-CoV-2, sigue presentando múltiples variantes, las cuales en muchos casos han tomado el nombre de la ciudad o país donde fueron detectados, la Organización Mundial de la Salud (OMS) ha estandarizado dichas variantes según el interés y preocupación que ocasionan, a continuación se detalla (2). El espectro de la enfermedad es amplio e incluye desde cuadros leves y autolimitados hasta neumonía atípica severa y progresiva, falla multiorgánica y muerte (3,4). El SARS-CoV-2, se detecta en la saliva de pacientes con enfermedad por coronavirus (COVID-19) ha sido que este fluido biológico fuera relevante en términos del diagnóstico y transmisión de la infección (5). Se cree que el virus se replica en la nariz y la garganta, como se evidencia por la alta carga viral en la etapa temprana de infección en estas áreas (6). Dada la patogenia de la enfermedad, hacer gárgaras o enjuagues bucales con un antiséptico que tiene actividad viricida contra el SARS-CoV-2 podría ayudar en el tratamiento y prevención de COVID-19, o suprimir la carga viral y reducir la propagación del virus (7,8). Existen vacunas eficaces para prevenir COVID-19, y algunos medicamentos muestran resultados promisorios; su disponibilidad en países en desarrollo aún es baja; por lo que es necesario evaluar alternativas que sean de bajo costo y alta disponibilidad. Esta revisión fue hecha para actualizar la evidencia científica disponible sobre la eficacia de los enjuagues naso-oro-faríngeos reduciendo la carga viral de SARS-CoV-2, mejorando los desenlaces de los pacientes, y/o previniendo la enfermedad COVID-19. OBJETIVO: El objetivo de esta revisión es actualizar la evidencia disponible sobre la eficacia de los enjuagues orales y/o lavados naso-oro-faríngeos reduciendo la carga viral, mejorando los desenlaces de los pacientes, y/o previniendo la enfermedad COVID-19 causada por el virus SARS-CoV-2. METODOLOGÍA: En la SRR N° 02-2021, se realizó una búsqueda sistemática hasta el 26 de abril de 2021 en las bases de datos MEDLINE (a través de PubMed), EMBASE/Ovid, LILACS/Biblioteca virtual en salud (BVS), y Cochrane Library, incluyendo términos en lenguaje natural y lenguaje estructurado (Tesauros, MeSH terms, DeCS terms) según cada base de datos para los términos de la pregunta PICO. Se revisaron también las referencias de los estudios incluidos y estudios sugeridos por los solicitantes de esta revisión. No se hizo búsqueda en la literatura gris. RESULTADOS: En la SRR N° 02-2021, se identificaron 15 estudios in vitro, 3 ensayos no controlados, 6 ensayos clínicos aleatorizados abiertos, y 2 revisiones sistemáticas relacionada a alguna de las 3 preguntas PICO. Los estudios hallados evaluaron diferentes enjuagues bucales, gárgaras faríngeas, lavados nasales, y espráis nasales/orales. Los componentes incluyeron Iodo-povidona (PVP-I), Clorhexidina (CHX), Peróxido de hidrogeno (H2O2), Dióxido de Cloro, los amonios cuaternarios Cetilpiridinio (CPC) y Decualinio, Iota y Kappa-carragenina, Xylitol, Octenidina, Polihexanida, Xylometazolina, Tramazolina, Oxymetazolina, Metilcelulosa, Delmopinol, Timol, Mentol, Eucaliptol, y combinaciones comerciales que además pueden incluir Etanol, Bicarbonato, y Cloruro de Sodio. Además de ellas, los estudios encontrados evaluaron otras 16 sustancias; así como preparados comerciales combinando dichas sustancias con Etanol, Bicarbonato, y/o Cloruro de Sodio. La PVP-I parece ser eficaz eliminando partículas virales en cultivos celulares; mientras que la evidencia para CHX y H2O2 es variable. No hubo suficiente evidencia para otras sustancias. Un solo estudio mostró que los Enjuagues de CHX son eficaces reduciendo el porcentaje de pacientes con virus detectable en la orofaringe. La evidencia para PVP-I, dióxido de cloro, y peróxido de hidrogeno fue insuficiente; y no se encontraron estudios para las otras sustancias. Según un solo estudio, el número de hospitalizaciones fue igual entre los que usaron o no enjuagues naso-oro-faríngeos de PVP-I; aunque su uso se asoció a supresión tiroidea. No hubo estudios para las otras sustancias, ni tampoco estudios evaluando ingreso a UCI o mortalidad. Para esta actualización de esta Nota Técnica, se identificaron 6 estudios de los cuales 2 revisiones sistemáticas, 1 estudio piloto clínico y 3 ensayos clínicos aleatorizados, entre las fechas 27 de abril hasta el 3 de diciembre de 2021. Los estudios hallados evaluaron diferentes enjuagues bucales, gárgaras faríngeas, lavados nasales, y espráis nasales/orales. Las sustancias más comúnmente estudiadas fueron Iodo-povidona (PVP-I), Clorhexidina (CHX), y Peróxido de hidrogeno (H2O2). CONCLUSIONES: De la SRR N° 02-2021, se identificaron 15 estudios in vitro, 3 ensayos no controlados, 6 ensayos clínicos aleatorizados (ECA) abiertos, y 2 revisiones sistemáticas relacionadas a alguna de las tres preguntas PICO. Para la actualización de esta Nota Técnica, se seleccionó estudios desde el 27 de abril hasta el 3 de diciembre de 2021 y se identificó 6 estudios de los cuales 2 revisiones sistemáticas, 2 estudios piloto clínico y 2 ensayos clínicos aleatorizados. Los estudios evaluaron diferentes preparaciones acuosas de enjuagues bucales, gárgaras faríngeas, lavados nasales, y espráis nasales/orales. Los componentes incluyeron Iodo-povidona (PVP-I), Clorhexidina (CHX), Peróxido de hidrogeno (H2O2), Dióxido de Cloro, los amonios cuaternarios, Cloruro de cetilpiridinio (CPC) y Decualinio, Iota y Kappa-carragenina, Octenidina, Polihexanida, Xylometazolina, Tramazolina, Oxymetazolina, Metilcelulosa, Xylitol, Delmopinol, Timol, Mentol, Eucaliptol, Dexpantenol, Zinc y combinaciones comerciales que además pueden incluir Etanol, Bicarbonato, y Cloruro de Sodio. En el estudio de Matthias Schürmann, et al., demostró que la solución de enjuague bucal (dexpantenol y zinc) puede reducir la carga viral tras la ejecución del procedimiento de enjuague bucal, pero está disminución de carga viral solo persiste hasta 6 horas. El enjuague bucal (dexpantenol y zinc), in vitro, disminuyeron la expresión de las citoquinas inflamatorias, mientras que en la muestra antiviral no se vio alterada de manera significativa. El gluconato de clorhexidina al 0,12%, dan como resultado una disminución de su carga viral del SARS-CoV-2 hasta 60 min en comparación con los que usaron placebo. Una limitación es que el ensayo semicuantitativo de RT-PCR mide las diferencias relativas de ARNm y no en la infectividad o viabilidad viral. De los estudios encontrados muestran resultados relacionados a la reducción de la carga viral en cultivos In vitro y en orofaringe de pacientes conCOVID-19, sin embargo, no hay evidencia que muestren la eficacia de estas sustancias en la prevención del COVID-19. De acuerdo a los estudios de las revisiones sistemáticas, concluye que no hay pruebas relacionadas con los beneficios y los riesgos del uso de antimicrobianos por parte del personal sanitario para protegerse cuando tratan a personas con COVID-19 o por parte de los pacientes. Además, advierten que es importante que los futuros estudios recojan y analicen la información sobre los efectos adversos y que se tenga en cuenta que los antisépticos también pueden eliminar los microorganismos de la boca o la nariz que son útiles para proteger el organismo contra las infecciones.

BACKGROUND: Antimicrobial agents are considered valuable adjuncts to mechanical methods of plaque control. However, their long-term use can be limited because of side effects. Therefore, using physiological substances is promising due to no risk of development, for example, of microbial resistances, allergies or DNA damaging. The lactoperoxidase-thiocyanate-hydrogen peroxide system (LPO-system) is a highly effective antimicrobial system. This study aimed to evaluate in a randomized study with a four-replicate cross-over design the effectiveness of two oral hygiene lozenges containing LPO-system in oral hygiene. RESULTS: After using the mouth rinse as positive control (A) and allocated test lozenges (B) (0.083% H2O2) & (C) (0.04% H2O2) for 4 days instead of the normal oral hygiene procedures (tooth brushing etc.), Listerine rinse (A) was statistically significantly more effective than the LPO-system-lozenge with 0.083% H2O2, the LPO-system-lozenge with 0.04% H2O2, and the placebo lozenge (D) in inhibiting plaque. Lozenges B and C were statistically significantly more effective than the placebo lozenge, but no statistically significant differences could be observed between them. The LPO-system-lozenge (B) reduced statistically significantly more S. mutans than the LPO-system-lozenge with (C) and the placebo lozenge (D). The LPO-system-lozenge (C) reduced statistically significantly more Lactobacilli than Listerine (A), the LPO-system-lozenge (B) and the placebo lozenge (D). There were no statistically significant differences in the total CFUs between Listerine rinse, the LPO-system-lozenge with 0.083% H2O2 (B), the LPO-system-lozenge with 0.04% H2O2 (C), and the placebo lozenge (D). On day 5 there were no differences of the OSCN--values between all A, B, C, and D. However, the SCN--values increased over the days in both LPO-system-lozenges (B/C). The statistically significant differences between B/C and A/D on day 5 were as followed: A to B p = 0.0268; A to C p = 0.0035; B to D p = 0.0051; C to D p = 0.0007. Only in the group of Listerine (A) increased the NO3-/NO2--quotient over the test time, which indicates a reduction of nitrate-reducing bacteria. On Day 5 the statistically significant difference between A and B was p = 0.0123. CONCLUSIONS: The results indicate that lozenges containing a complete LPO-system, inhibiting plaque regrowth and reducing cariogenic bacteria, may be used in the daily oral hygiene.

Caffeine mouth rinsing (CMR) has been shown to enhance exercise performance. However, no studies have analyzed the effects of different dosages of CMR on muscular performance. Therefore, the purpose of this study was to examine the effects of different dosages of CMR on strength (bench press 1 repetition maximum (1-RM)) and muscular endurance (60% of 1-RM repetitions to failure) in resistance-trained males. Fourteen resistance-trained males (age: 23 ± 2 years, height: 179 ± 3 cm, body mass: 83 ± 4 kg, BMI: 17 ± 2 kg/m2) completed four conditions in random order. The four conditions consisted of a mouth rinse with 25 mL solutions containing either 1% (250 mg) of CMR (low dose of CMR: LCMR), 2% (500 mg) of CMR (moderate dose of CMR: MCMR), 3% (750 mg) of CMR (high dose of CMR: HCMR) and sweetened water (placebo: PLA) for 5 s prior to a bench press strength and muscular endurance test. Maximal strength, muscular endurance, heart rate (HR) and ratings of perceived exertion (RPE) were recorded for each condition. There were no significant differences in strength (p = 0.30) and HR (p = 0.83) between conditions. HCMR significantly increased muscular endurance performance (p = 0.01) and decreased RPE values (p = 0.01). In conclusion, CMR did not affect bench press 1-RM strength performance, but muscular endurance responses to CMR seems to be dose-dependent.

A 50-year-old woman was referred to the clinic reporting oral discomfort during the previous month and plaques of a white removable slough. Diagnosis of pseudomembranous oral candidiasis was clinically confirmed. When the tongue and palatal mucosa were wiped with gauze, the soft yellowish-white slough detached revealing the erythematous surface beneath. The patient also presented paranoid schizophrenia and severe depression, pulmonary emphysema, and two vertebral hernias. She was a smoker (10 cigarettes per day) with xerostomia that was being treated with: bupropion, reboxetine, quetiapine, trazadone clotiapine, pregabalin, fentanyl (patches), and alprazolam. To minimize the risk of potential drug interactions, a mouthwash containing 0.05% chlorhexidine + 0.05% cetylpyridinium chloride was prescribed three times a day for two weeks. At the end of the two weeks, the candidiasis had abated.

SARS-CoV-2 infection in hospital areas is of a particular concern, since the close interaction between health care personnel and patients diagnosed with COVID-19, which allows virus to be easily spread between them and subsequently to their families and communities. Preventing SARS-CoV-2 infection among healthcare personnel is essential to reduce the frequency of infections and outbreaks during the pandemic considering that they work in high-risk areas. In this research, silver nanoparticles (AgNPs) were tested in vitro and shown to have an inhibitory effect on SARS-CoV-2 infection in cultured cells. Subsequently, we assess the effects of mouthwash and nose rinse with ARGOVIT® silver nanoparticles (AgNPs), in the prevention of SARS-CoV-2 contagion in health workers consider as high-risk group of acquiring the infection in the General Tijuana Hospital, Mexico, a hospital for the exclusive recruitment of patients diagnosed with COVID-19. We present a prospective randomized study of 231 participants that was carried out for 9 weeks (during the declaration of a pandemic). The "experimental" group was instructed to do mouthwash and nose rinse with the AgNPs solution; the "control" group was instructed to do mouthwashes and nose rinse in a conventional way. The incidence of SARS-CoV-2 infection was significantly lower in the "experimental" group (two participants of 114, 1.8%) compared to the "control" group (thirty-three participants of 117, 28.2%), with an 84.8% efficiency. We conclude that the mouth and nasal rinse with AgNPs helps in the prevention of SARS-CoV-2 infection in health personnel who are exposed to patients diagnosed with COVID-19.

The idea of the local drug delivery system is getting popular nowadays to treat gingivitis and periodontitis. The method of delivering the drug locally is quite easy and requires minimal intervention. This delivery system not only treats the periodontal diseases effectively but also prevents the side effects linked with the use of the drugs which are used orally for longer periods to cure these diseases. Chlorhexidine (CHX) is being widely used to treat these conditions because of its broad spectrum anti-bacterial effect and is found to be more effective in lowering plaque formation. The aim of this study was to appraise the effect of the local drug delivery system by using 1% CHX gel in patients with periodontal diseases. 1% CHX gel was prepared and its physicochemical characteristics were then assessed. Clinical parameters and inflammatory salivary biomarkers were evaluated in two groups of patients. Group I: standard treatment group. Group II: gel treatment group. These parameters were evaluated before treatment and after 4 weeks of treatment. 1% CHX gel was highly effective in reducing gingivitis and periodontitis by using the local drug delivery system which allowed the drug to retain into the periodontal pocket for prolong period of time.

OBJECTIVES: To evaluate the effectiveness of hydrogen peroxide (H2O2) in the form of mouthwash and nasal spray as an auxiliary treatment for coronavirus disease 2019 (COVID-19). METHODS: Forty hospitalized patients who tested positive for severe acute respiratory syndrome coronavirus 2 using a reverse-transcription polymerase chain reaction test were evaluated. They were randomly divided into an experimental group (n= 20; gargling with 1.0% H2O2 and nasal wash with 0.5% H2O2) or a control group (n= 20). The solutions were used for 7 days and the patients were monitored every 2 days, for a total of 8 days. At check-ups, patients were asked about their symptoms and possible adverse effects of the solutions. The presence and severity (mild, moderate, or severe) of symptoms were recorded. Data were compared using the Student test and the Fisher exact test (α= 0.05). RESULTS: There was no significant difference between the 2 groups in the length of hospital stay (p= 0.65). The most frequent symptom on day 0 was coughing (72.0% in the experimental group and 76.5% in the control group), which abated over time. There was no significant difference between the groups in the evaluated symptoms. Most (75.0%) of the patients in the experimental group presented a reduction in dyspnea between days 0 and 2. Few patients reported adverse effects from the use of the solutions. CONCLUSIONS: H2O2 as a mouthwash and nasal spray is safe to use. There is insufficient evidence to demonstrate that H2O2 is effective as an auxiliary treatment for hospitalized COVID-19 patients.
