Dentists are health care workers with the highest risk of exposure to COVID-19, because the oral cavity is considered to be a reservoir for SARS-CoV-2 transmission. The identification of SARS-CoV-2 in saliva, the generation of aerosols, and the proximity to patients during dental procedures are conditions that have led to these health care workers implementing additional disinfection strategies for their protection. Oral antiseptics are widely used chemical substances due to their ability to reduce the number of microorganisms. Although there is still no evidence that they can prevent the transmission of SARS-CoV-2, some preoperative oral antiseptics have been recommended as control measures, by different health institutions worldwide, to reduce the number of microorganisms in aerosols and droplets during dental procedures. Therefore, this review presents the current recommendations for the use of oral antiseptics against SARS-CoV-2 and analyzes the different oral antiseptic options used in dentistry.
Revisión bibliogRáfica RESUMEN La periodontitis es una enfermedad crónica inflamatoria que produce una destrucción de las estructuras de soporte del diente, provocando su pérdida. Los agentes bacterianos organizados en forma de biofilm son clave en el desarrollo de la periodontitis pero su presencia por sí sola no siempre puede explicar las características clínico-patológicas de la enfermedad. La evidencia sugiere que los herpesvirus y las bacterias podrían cooperar de forma sinérgica en el desarrollo de la periodontitis, respaldando una asociación, ya que una infección por herpesvirus activo puede inducir la inmunosupresión, llevando a un sobrecrecimiento de bacterias patógenas, y potencialmente convertir la gingivitis en periodontitis o la periodontitis estable en enfermedad progresiva. Algunos estudios indicaron un riesgo significativamente mayor de periodontitis acompañada por una mayor prevalencia de detección de herpesvirus. Millones de copias genómicas de virus humanos se pueden alojar en lesiones periodontales, y los herpesvirus son los virus más investigados en periodontología. Los pacientes con periodontitis presentan niveles séricos elevados de anticuerpos contra el herpesvirus y mediadores inflamatorios.
