effect of mouthwashes on viable viral load of SARS-CoV-2 in saliva: a pilot study.

Current data on the efficacy of antiseptic mouthwashes to reduce viral load are contradictory. Firstly, data indicate very strong virucidal effects that are not replicated in clinical studies. Secondly, most clinical studies identify a limited effect, do not include a control/placebo group, or do not evaluate viral viability in an infection model.

Clinical evaluation of antiseptic mouth rinses to reduce salivary load of SARS-CoV-2.

Most public health measures to contain the COVID-19 pandemic are based on preventing the pathogen spread, and the use of oral antiseptics has been proposed as a strategy to reduce transmission risk. The aim of this manuscript is to test the efficacy of mouthwashes to reduce salivary viral load in vivo. This is a multi-centre, blinded, parallel-group, placebo-controlled randomised clinical trial that tests the effect of four mouthwashes (cetylpyridinium chloride, chlorhexidine, povidone-iodine and hydrogen peroxide) in SARS-CoV-2 salivary load measured by qPCR at baseline and 30, 60 and 120 min after the mouthrinse.

Delivery of Health Care by Spanish Dental Hygienists in Private and Public Dental Services during the COVID-19 De-Escalation Phase (June 2020): A Cross-Sectional Study.

Background: The first wave of the COVID-19 pandemic in Spain posed a major challenge for Spanish dental professionals. The objective of this work is to describe the dental hygienists' work status and employment patterns during the de-escalation phase in order to analyse the standards of knowledge, compliance with official recommendations, and dental activities both in the public health service and in the private sector.

Material And Methods: A cross-sectional questionnaire was answered by Spanish dental hygienists via WhatsApp, Facebook, and Instagram.

Preventive Antibiotic Prescribing Habits among Professionals Dedicated to Oral Implantology: An Observational Study.

The prescription of preventive antibiotics (PA) in oral implantology is a controversial issue. The study aimed to determine the prescribing habits of PA in professionals dedicated to oral implantology in various treatments in healthy and at-risk patients. This is a cross-sectional observational study based on the STROBE (Strengthening the Reporting of Observational Studies in Epidemiology) guidelines.

The COVID-19 respiratory manifestations go from mild symptoms similar to those of a common cold to severe pneumonia with respiratory distress syndrome, septic shock and multiorgan failure. The disease is caused by the SARS-CoV-2 virus, whose transmission mechanism most relevant to dentistry is through respiratory droplets and possibly also aerosols, as well as direct contact with mucous membranes of the nose, mouth or eye via contaminated hands or objects. The professionals of the dental health units have a high risk exposure since they work at short distances (less than 1 m from the head of the patient) in the oral cavity, where a maximal expression of possible cell receptors for the virus has been reported.
