Povidone-Iodine as a Pre-Procedural Mouthwash to Reduce the Salivary Viral Load of SARS-CoV-2: A Systematic Review of Randomized Controlled Trials.

The use of pre-procedural rinses has been investigated to reduce the number of viral particles and bacteria in aerosols, potentially decreasing the risk of cross-infection from severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) during medical and dental procedures. This review aims to confirm whether there is evidence in the literature describing a reduction in salivary load of SARS-CoV-2 when povidone-iodine (PVP-I) is used as a pre-intervention mouthwash. An search of the MEDLINE, Embase, SCOPUS, and the Cochrane library databases was conducted. The criteria used followed the PRISMA® Statement guidelines. Randomized controlled trials investigating the reduction of salivary load of SARS-CoV-2 using PVP-I were included. Ultimately, four articles were included that met the established criteria. According to the current evidence, PVP-I is effective against SARS-CoV-2 in saliva and could be implemented as a rinse before interventions to decrease the risk of cross-infection in healthcare settings.

Efficacy of Pre-Procedural Mouthwashes against SARS-CoV-2: A Systematic Review of Randomized Controlled Trials.

The oral mucosa is one of the first sites to be affected by the SARS-CoV-2. For this reason, healthcare providers performing aerosol-generating procedures (AGPs) in the oral cavity are at high risk of infection with COVID-19. The aim of this systematic review is to verify whether there is evidence in the literature describing a decrease in the salivary viral load of SARS-CoV-2 after using different mouthwashes. An electronic search of the MEDLINE database (via PubMed), Web of Science, SCOPUS, and the Cochrane library database was carried out. The criteria used were those described by the PRISMA® Statement. Randomized controlled trial studies that have used mouthwashes as a form of intervention to reduce the viral load in saliva were included. The risk of bias was analyzed using the Joanna Briggs Institute Critical Appraisal Tool. Ultimately, eight articles were included that met the established criteria. Based on the evidence currently available in the literature, PVP-I, CHX and CPC present significant virucidal activity against SARS-CoV-2 in saliva and could be used as pre-procedural mouthwashes to reduce the risk of cross-infection.

Virucidal Activity of Different Mouthwashes against the Salivary Load of SARS-CoV-2: A Narrative Review.

The saliva of COVID-19-confirmed patients presents a high viral load of the virus. Aerosols generated during medical and dental procedures can transport the virus and are a possible causative agent of cross-infection. Since the onset of the pandemic, numerous investigations have been attempting to mitigate the risk of transmission by reducing the viral load in saliva using preprocedural mouthwashes. This study aims to review the most up-to-date in vitro and in vivo studies investigating the efficacy of different mouthwashes on reducing the salivary viral load of SARS-CoV-2, giving particular attention to the most recent randomized control trials published.

Implantes cigomáticos: una puesta al día / Zygomatic implants: an up-to-datepatient

Un maxilar con reabsorción ósea moderada o severa representa un reto para la implantología contemporánea. El tratamiento convencional con implantes no puede ser realizado en situaciones de pérdida ósea avanzada, ni en situaciones que impliquen proximidad del seno maxilar al lugar de la intervención, dado que no hay suficiente hueso para anclar los implantes sin la realización de técnicas de regeneración ósea. El objetivo de este trabajo es estudiar la viabilidad de los implantes cigomáticos como alternativa a las técnicas de regeneración ósea, así como la técnica quirúrgica y sus variantes, complicaciones y la supervivencia. La evaluación clínica indica un alto índice de supervivencia. Los resultados sugieren que la rehabilitación sobre implantes cigomáticos en grandes atrofias maxilares es segura y predecible, siendo una excelente alternativa a los injertos óseos. Por este motivo los implantes cigomáticos constituyen un posible nuevo ‘Gold Standard’ para el manejo de la reabsorción ósea avanzada (AU)

The severely atrophic maxilla represents a challenge for the contemporaneous implantology. Conventional treatment using dental implants cannot be performed in situations where there is an advanced bone loss, neither in situations, involving extensive maxillary sinuses which lead to inadequate amount of bone tissue for the anchorage of implants without the performance of bone grafting techniques. The aim of this paper is to study the viability of the use of zygomatic implants as an alternative to bone augmentation procedures. A revision of surgical techniques, variations, complications and survival is included. Clinical assessment indicates a high survival rate. The reviewed results suggest that oral rehabilitation using zygomatic implants, in severely atrophic maxillas is a safe and predictable procedure. Being an excellent alternative to bone augmentation techniques, the use of zygomatic implants represents a possible new Gold Standard in the treatment of advanced bone resorption (AU)
