Effective in vitro inactivation of SARS-CoV-2 by commercially available mouthwashes.

Infectious SARS-CoV-2 can be recovered from the oral cavities and saliva of COVID-19 patients with potential implications for disease transmission. Reducing viral load in patient saliva using antiviral mouthwashes may therefore have a role as a control measure in limiting virus spread, particularly in dental settings. Here, the efficacy of SARS-CoV-2 inactivation by seven commercially available mouthwashes with a range of active ingredients were evaluated in vitro. We demonstrate ≥4.1 to ≥5.5 log10 reduction in SARS-CoV-2 titre following a 1 min treatment with commercially available mouthwashes containing 0.01-0.02 % stabilised hypochlorous acid or 0.58 % povidone iodine, and non-specialist mouthwashes with both alcohol-based and alcohol-free formulations designed for home use. In contrast, products containing 1.5 % hydrogen peroxide or 0.2 % chlorhexidine gluconate were ineffective against SARS-CoV-2 in these tests. This study contributes to the growing body of evidence surrounding virucidal efficacy of mouthwashes/oral rinses against SARS-CoV-2, and has important applications in reducing risk associated with aerosol generating procedures in dentistry and potentially for infection control more widely.

Removable partial dentures: The clinical need for innovation.

STATEMENT OF PROBLEM: The number of partially dentate adults is increasing, and many patients will require replacement of missing teeth. Although current treatment options also include fixed partial dentures and implants, removable partial dentures (RPDs) can have advantages and are widely used in clinical practice. However, a significant need exists to advance materials and fabrication technologies because of the unwanted health consequences associated with current RPDs. PURPOSE: The purpose of this review was to assess the current state of and future need for prosthetics such as RPDs for patients with partial edentulism, highlight areas of weakness, and outline possible solutions to issues that affect patient satisfaction and the use of RPDs. MATERIAL AND METHODS: The data on treatment for partial edentulism were reviewed and summarized with a focus on currently available and future RPD designs, materials, means of production, and impact on oral health. Data on patient satisfaction and compliance with RPD treatment were also reviewed to assess patient-centered care. RESULTS: Design, materials, ease of repair, patient education, and follow-up for RPD treatment all had a significant impact on treatment success. Almost 40% of patients no longer use their RPD within 5 years because of factors such as sociodemographics, pain, and esthetics. Research on RPD-based treatment for partial edentulism for both disease-oriented and patient-centered outcomes is lacking. CONCLUSIONS: Future trials should evaluate new RPD materials and design technologies and include both long-term follow-up and health-related and patient-reported outcomes. Advances in materials and digital design/production along with patient education promise to further the application of RPDs and improve the quality of life for patients requiring RPDs.

Dentinogenesis imperfecta: full-mouth rehabilitation using implants and sinus grafts--a case report.

UNLABELLED: This case report outlines one possible treatment modality to manage the developmental abnormality dentinogenesis imperfecta (DI). In this case, the patient's dentition is restored using a combination of full-coverage crowns for the remaining teeth and implant-supported crowns to replace missing teeth in a re-organized occlusal scheme. The case also demonstrates the effective use of the sinus graft procedure with simultaneous placement of dental implants. This paper also aims to make the reader aware of the current thinking behind treatment delivered to this group of patients, focusing on full-mouth rehabilitation using a combination of implant-supported and conventional metal ceramic crowns. CLINICAL RELEVANCE: For the general dental practitioner this case outlines the prevalence and cause of DI. It demonstrates how early diagnosis and appropriate referral has an impact on future treatment.

Aesthetic preview: a novel approach.

UNLABELLED: Planning the final aesthetic result of restorative treatment is a key skill needed by the clinician to ensure predictable success. This paper aims to review current techniques that may be used by clinicians for an aesthetic preview, whilst also highlighting a simple technique that may be readily utilized in practice. CLINICAL RELEVANCE: It is considered good practice to give patients an aesthetic preview of the end result prior to commencing active treatment. This article demonstrates the different techniques available and those that are easily utilized in general practice. The aesthetic preview is of benefit to both the clinician and technician in defining treatment goals and improving communication.
