RESUMO

Background: Many antimicrobial compounds in mouthwashes can have a negative impact on the oral microbiome. O-cymen-5-ol, a compound derived from a phytochemical, has a targeted mode of action and is being used as an alternative. However, its effect on the native oral microbiome is unknown. Aim: To assess the effect of a mouthwash formulated with o-cymen-5-ol and zinc chloride on the oral microbiome of healthy individuals. Methods: A mouthwash formulated with o-cymen-5-ol and zinc chloride was administered to a cohort of 51 volunteers for 14 days, while another cohort of 49 volunteers received a placebo. The evolution of the oral microbiome in both groups was analysed using a metataxonomic approach. Results: Analysis of the oral microbiome showed that the mouthwash selectively targeted potential oral pathogens while maintaining the integrity of the rest of the microbiome. Specifically, the relative abundance of several potentially pathogenic bacterial taxa, namely Fusobacteriota, Prevotella, Actinomyces, Granulicatella, Abiotrophia, Lautropia, Lachnoanaerobaculum, Eubacterium (nodatum group) and Absconditabacteriales (SR1) decreased, while the growth of Rothia, a nitrate-reducing bacterium beneficial for blood pressure, was stimulated. Conclusions: The use of o-cymen-5-ol and zinc chloride as antimicrobial agents in oral mouthwashes is a valuable alternative to classical antimicrobial agents.

RESUMO

Chlorhexidine (CHX) is one of the most widely used antiseptics in the oral cavity due to its high antimicrobial potential. However, many authors have stated that the effect of CHX in nonsurgical periodontal therapy is hampered by its rapid elimination from the oral environment. The aim of this study was to determine the antibacterial efficacy of a new compound of chlorhexidine 0.20% + cymenol (CYM) 0.10% on a multispecies biofilm. For this, an in vitro study was designed using a multispecies biofilm model of Streptococcus mutans, Fusobacterium nucleatum, Prevotella intermedia, and Porphyromonas gingivalis. Quantification of the microbial viability of the biofilm was performed using 5-cyano-2,3-ditolyl tetrazolium-chloride (CTC) to calculate the percentage of survival, and the biofilms were observed using a a confocal laser scanning microscopy (CLSM). It was observed that the bactericidal activity of the CHX + cymenol bioadhesive gel was superior to that of the CHX bioadhesive gel, in addition to higher penetrability into the biofilm. Therefore, there was greater elimination of bacterial biofilm with the new compound of chlorhexidine 0.2% plus cymenol 0.1% in a bioadhesive gel form compared to the formulation with only chlorhexidine 0.2% in a bioadhesive gel form.

RESUMO

Introducción: la hiperestesia dentinaria se caracteriza por un dolor intenso y breve asociado a la exposición de estímulos térmicos, táctiles, osmóticos o químicos. De prevalencia creciente, reduce la calidad de vida del paciente. Objetivo: evaluar la eficacia, aceptabilidad y tolerancia de un dentífrico con dióxido de silicio obliterante, nitrato potásico y monofluorofosfato sódico en pacientes con hiperestesia dentinaria. Métodos: estudio observacional y longitudinal (n= 22) en el que se aplicó el dentífrico 3 veces/día durante 28 días. Se realizó una evaluación clínica, antes y después de la aplicación, a las 48 horas, a las 96 horas y los días 7, 14, 21 y 28 del estudio. Se evaluó su eficacia en términos de reducción de la hipersensibilidad dental determinada mediante técnica táctil (escala de calificación verbal) y de chorro de aire (escala de Schiff). En cada visita se valoró la tolerancia del producto. Los pacientes valoraron el grado de hipersensibilidad y su percepción del producto mediante un cuestionario de evaluación subjetiva. El estudio se realizó bajo los principios de Buena Práctica Clínica. Resultados: la hipersensibilidad dental se redujo en todos los puntos temporales del estudio y fue significativa (p< 0,05) a partir del día 5. Esta mejoría fue sostenida y aumentó a medida que avanzó el tratamiento. El día 29 la hipersensibilidad media se redujo en un 85 por ciento respecto al valor basal en todos los pacientes. El 91 por ciento de los participantes opinó que el dentífrico había cumplido sus expectativas. No se observó ninguna reacción adversa derivada del uso del producto. Conclusiones: el dentífrico, administrado 3 veces/día, consiguió una reducción de la hipersensibilidad dental, significativa a partir del día 5, que fue aumentando con el tiempo. El producto presentó muy buena aceptabilidad y tolerancia(AU)


Introduction: dentin hypersensitivity is characterized by sharp pain of short duration associated with exposure to thermal, tactile, osmotic or chemical stimuli. Dentin hypersensitivity is a disorder of growing prevalence which reduces the quality of life of patients. Objective: evaluate the efficacy, acceptability and tolerance of a toothpaste with precipitated silica, potassium nitrate and sodium monofluorophosphate in patients with dentin hypersensitivity. Methods: an observational longitudinal study was conducted (n= 22) in which the toothpaste was applied 3 times a day for 28 days. Clinical assessment was performed before and after the application, at 48 hours, at 96 hours and on days 7, 14, 21 and 28 of the study. Efficacy was evaluated in terms of dental hypersensitivity reduction as determined by tactile (Verbal Rating Scale) and air jet (Schiff scale) techniques. Tolerance to the product was assessed in every visit. Patients ranked the degree of hypersensitivity and their perception of the product by means of a subjective assessment questionnaire. The study complied with Good Clinical Practice principles. Results: areduction was observed in dental hypersensitivity at all time points throughout the study, and it was significant (p< 0,05) as of day 5. This improvement was sustained and increased as treatment progressed. On day 29 mean hypersensitivity had reduced 85 percent with respect to baseline value in all patients. 91 percent of the patients stated that the toothpaste had met their expectations. No adverse reaction attributable to the product was observed. Conclusions: applied 3 times/day, the toothpaste obtained a reduction in dental hypersensitivity, which was significant as of day 5. This improvement increased over time. The product had very good acceptability and tolerance(AU)

RESUMO

Introducción: La hiperestesia dentinaria se caracteriza por un dolor intenso, de corta duración, asociado a la exposición de la dentina en respuesta a estímulos térmicos, táctiles, osmóticos o químicos. De prevalencia creciente, reduce la calidad de vida del paciente. El objetivo principal fue evaluar la eficacia de un gel bioadhesivo dental con dióxido de silicio obliterante, nitrato potásico y monofluorofosfato sódico en pacientes con hiperestesia dentinaria. Como objetivo secundario se valoraron su aceptabilidad y tolerancia. Métodos: El producto se aplicó durante 14 días, 3 veces/día, después de la limpieza dental y se mantuvo sin aclarar 30 minutos (n=19). Se evaluó su eficacia mediante exploración odontológica por técnica táctil y de chorro de aire. Al finalizar el estudio los pacientes completaron un cuestionario de percepción del producto. Resultados: La evaluación odontológica mostró una reducción significativa de la hipersensibilidad dental en todos los puntos temporales del estudio (p<0,05) mediante técnica táctil y de chorro de aire. Esta mejoría fue sostenida y aumentó a medida que avanzó el tratamiento. Todas las preguntas sobre la eficacia del producto y sus características organolépticas percibidas tuvieron una respuesta positiva. Los resultados del tratamiento fueron considerados muy satisfactorios/satisfactorios por un 95% de los pacientes. No se observó ninguna reacción adversa significativa derivada del uso del producto. Conclusiones: El gel bioadhesivo dental con dióxido de silicio obliterante, nitrato potásico y monofluorofosfato sódico, administrado 3 veces/día, consiguió una reducción significativa de la hipersensibilidad dental, mejoría que fue aumentando con el tiempo.

Introduction: Dentin hypersensitivity is characterized by an acute pain of short duration associated with exposure of dentin to thermal, tactile, osmotic or chemical stimuli. It shows increasing prevalence and reduces the quality of life of patients. The main objective was to evaluate the effectiveness of a dental bio-adhesive gel with precipitated amorphous silica, potassium nitrate, and sodium monofluorophosphate in patients with dentin hypersensitivity. The secondary objective was to evaluate acceptability and tolerance of the product. Methods: The product was applied for 14 days, 3 times / day after habitual cleanliness routine and was not rinsed for 30 minutes. Its efficacy was evaluated by sensitive touch and air jet techniques. At the end of the study the patients filled a subjective questionnaire about the perception of the product. Results: The dental evaluation showed a significant reduction of dental hypersensitivity at all time points of the study (p<0.05) according to the sensitive touch and air jet technique results. This improvement increased as the treatment progressed. All questions about the effectiveness of the product and its organoleptic characteristics received a positive answer. Treatment results were considered very satisfactory or satisfactory by 95% of patients. No significant adverse reactions associated to the product were observed. Conclusions: Dental bio-adhesive gel with precipitated amorphous silica, potassium nitrate, and sodium monofluorophosphate, administered 3 times / day resulted in a significant reduction of dental hypersensitivity, and this improvement increased with time. The product showed very good acceptability and tolerance (AU)
