Objetivo: Determinar la actividad antibacteriana de un aceite ozonizado de girasol en Porphyromonas gingivalis agente causal de la enfermedad periodontal, 2019. Tipo y diseño: el tipo de investigación fue experimental, prospectivo, longitudinal, analítico. La población estuvo conformada por cepas de Porphyromonas gingivales (CODIGO ATCC 33277), en 10 placas Petri, conformadas por 60 unidades de muestra. La selección del número de muestra se hizo del tipo no probabilístico aleatorio simple por conveniencia, empleándose una ficha de recolección de datos elaborada y validada para la presente investigación, registrándose 30 datos a los 72 y 30 datos a las 120 horas. La actividad antibacteriana se estimó según formación del halo de inhibición y sensibilidad bacteriana en la escala de Duraffourd comparada con clorhexidina 0,12% + cetilpiridinio 0,05% y aceite de girasol 100%. Es...

   COVID-19 is a communicable disease caused by severe acute respiratory syndrome (SARS-COV-2). The oral cavity is a route of entry for SARS-COV-2. Oral epithelial cells, taste buds, and glands play an important role as they express cellular entry factors for SARS-COV-2, such as angiotensin-converting enzyme 2 (ACE2) and type 2 transmembrane serine protease (TMPRSS2).Oropharyngeal manifestations were found in the oral cavity, mainly in the tongue and hard palate. In mild cases, the use of alcohol-free mouthwash Chlorhexidine 0.12%, antibiotic therapy, and in severe cases photobiomodulation therapy was indicated, in other cases the lesions disappeared as the disease subsided.The virus can be detected in saliva, even before symptoms of COVID-19 appear. Reducing oral viral load could lead to a lower risk of transmission mainly through salivary droplets or aerosols. The use of mouthwashes...

Objectives: To determine the antifungal activity of two essential oils (EO), the EO of Cinnamomum zeylanicum (C. zeylanicum) at 100% and the EO Minthostachys mollis (M. mollis) at 100% on the strain of Candida albicans (C. albicans) ATCC 10231. Materials and Methods: The sample consisted of 45 cultures of C. albicans ATCC 10231 strains, divided into three groups: group 1: 100% C. zeylanicum EO, nystatin 100 000 IU/ml (positive control), sterile distilled water (negative control), group 2: 100% M. mollis EO, nystatin 100 000 IU/ml (positive control), sterile distilled water (negative control), and group 3: the combination of both essential oils and the corresponding positive and negative control used. The formation of growth inhibition halos was evaluated in millimeters. The Duraffourd scale was used to establish the sensitivity after 48 hours of incubation. Results: The 100% C. zeylanicu...
