The proximity to the patient during dental care, high generation of aerosols, and the identification of SARS-CoV-2 in saliva have suggested the oral cavity as a potential reservoir for COVID-19 transmission. Mouthwashes are widely-used solutions due to their ability to reduce the number of microorganisms in the oral cavity. Although there is still no clinical evidence that they can prevent the transmission of SARS-CoV-2, preoperative antimicrobial mouth rinses with chlorhexidine gluconate (CHX), cetylpyridinium chloride (CPC), povidone-iodine (PVP-I), and hydrogen peroxide (H 2 O 2) have been recommended to reduce the number of microorganisms in aerosols and drops during oral procedures. This paper therefore aims to provide a comprehensive review of the current recommendations on the use of mouthwashes against the COVID-19 pandemic and to analyse the advantages and disadvantages of most conventional antiseptic mouthwashes used in dentistry.

With the spread of coronavirus disease 2019 (COVID-19), strict isolation strategies to limit virus transmission have been applied worldwide. The lockdown has affected and challenged different medical areas. Doctors, nurses, dentists, and other health care workers are concerned about contagion, not only for themselves, but also for their families and colleagues. Furthermore, the oral mucosa has been accepted as a high-risk route of transmission for COVID-19. In many countries, dentists have been forced to stop working during quarantine until further notification. Isolation and its financial impact have produced physical and psychological pressure, depression, social anxiety, and other mental health concerns. This article aims to provide a comprehensive review of the consequences of past epidemics on mental health and to assess possible aspects that might be associated with mental implications in dentists during the COVID-19 pandemic. Finally, some concrete actions to avoid subsequent potential consequences are recommended.

El manejo de esta afección tiene por objetivo el control del dolor durante el periodo de curación del cuadro, lo cual se logra fundamentalmente mediante medidas paliativas.El objetivo de esta revisión de la literatura es obtener suficiente información sobre las causas y otros factores que podrían estar involucrados en esta complicación postoperatoria, así como las opciones de tratamiento que existen actualmente. a b s t r a c tDry socket is the most common postoperative complication, due to problems in alveolar wound healing after tooth extraction. The management of this condition aims to control pain during the healing period, and is mainly achieved with palliative drugs.The aim of this literature review is to obtain sufficient information on the causes and any other factors that could be involved in this post-operative complication, as well as the currently available treatment options. IntroducciónLa alveolitis seca es la complicación postoperatoria más frecuente después de una extracción dental 1 , con una frecuencia de aparición comúnmente entre el 1 al 5% 2,3 , aunque existen reportes de hasta un incidencia del 70% 4 de los pacientes en la práctica dental. Se ha aceptado que la alveolitis tiene una etiología multifactorial (sistémica y local) 5 , lo que a su Correo electrónico: avergarab@outlook.com vez ha producido que se enumeren diferentes opciones de tratamiento 6 . Actualmente el manejo de la alveolitis está enfocado a aliviar la sintomatología que refiere el paciente, mediante el uso de agentes paliativos, enjuagues 7 e incluso fármacos. Sin embargo, hasta el momento no existe un consenso establecido para su manejo, pues su exacta patogénesis ha sido aún poco estudiada 8,9 .

The aim of this study was to compare the effect of the application of a flowable resin composite coating, over a collagen sponge stabilized with suture, on postoperative pain after free gingival graft harvesting. Thirty‐two free gingival grafts were harvested from the palate in 32 patients, who were subsequently randomized to have only a collagen sponge stabilized with sutures applied to the palatal wound (control), or to have the collagen sponge coated with a flowable resin composite (test). Patients were observed for 14 days, and the pain level was evaluated by using a numerical rating scale. The consumption of analgesics during the postoperative period and the characteristic of the graft were also analyzed. The patients in the test group reported having experienced significantly less pain statistically than the patients in the control group throughout the study. The consumption of analgesics was lower in the test group. The dimensions of harvested grafts in the control and test groups showed no significant differences in height, width, and thickness. In conclusion, the addition of flowable resin composite coating to the hemostatic collagen sponge on the palatal wound following free gingival graft harvesting helped to minimize postoperative pain.

Comfort and compliance with the use of facemasks during COVID -19 infection Dear Editor, I found very interesting the article wrote by Swennen et al. 1 about custom-made 3Dprinted face masks. The fabrication of this prototype is a promising idea and is a feasible alternative since medical, N95 and FFP2/3 masks are in shortage in different countries 2 .With respect to the authors, what I found essential before its massive production is its use in real-life situations. The reliability of mask not only depends on face seal leakage but also on its correct use, compliance and fitting 3 .Healthcare workers (HW) have to wear a mask for long periods and if the person feels discomfort wearing it, it would affect the compliance during its use. The discomfort experienced by HW has been associated with tight-fit models 4 It was previously demonstrated that flat fold N95 respirators offer and enhanced facial comfort without compromising its protection level 5 .In my opinion, the idea is motivating but I should recommend the fabrication of a thinner mask to enhance general comfort in HW.It isalso important toscan the face inneutral and while performing typical facial expressions as smiling, these facial movements may increase contact pressure at the chin 6 .Seal leakage, fitting, and compliance have to be validated in future studies. Since there is a lack of time to perform them, I strongly recommend the fabrication of thin-ner custom-made 3D-printed facemasks and the use of face visors as a barrier. FundingNone.
