Safety protocols for dental care during the COVID-19 pandemic: the experience of a Brazilian hospital service.

The coronavirus disease (COVID-19) has been prioritized in relation to other illnesses considered critical, such as cancer, cardiovascular diseases/stroke, diabetes, and autoimmune diseases. The management of patients with these diseases involves dental care to reduce systemic complications caused by odontogenic infections, and/or to treat oral manifestations of systemic comorbidities. In this regard, the dental care of these individuals must be guaranteed during the pandemic. Although a high risk of exposure to and catching of COVID-19 is expected to befall dental professionals, biosafety guidelines reduce the likelihood of infection. Thus, the current scenario poses challenges, and offers decision-making approaches and tools that facilitate the management of individuals with oral manifestations of chronic and/or critical diseases, using hospital-based services. This article presents an overview for hospital service providers who are at the forefront of COVID-19 care, including a secure protocol, and clinical guidelines based on the experience of the Hospital das Clínicas in Belo Horizonte, a public referral service, supported by the Brazilian National Health System.

Abstract The coronavirus disease (COVID-19) has been prioritized in relation to other illnesses considered critical, such as cancer, cardiovascular diseases/stroke, diabetes, and autoimmune diseases.

In this regard, the dental care of these individuals must be guaranteed during the pandemic. Although a high risk of exposure to and catching of COVID-19 is expected to befall dental professionals, biosafety guidelines reduce the likelihood of infection.

Medial canthal region as an external reference point in orthognathic surgery.

PURPOSE: The aim of this investigation was to evaluate the effectiveness of using the medial canthal region (MCR) as an external reference point to determine the vertical dimension during maxillary repositioning as planned in model surgery and predictive tracing. MATERIALS AND METHODS: The analyzed group consisted of 43 consecutive patients who underwent maxillary or bimaxillary orthognathic surgery. Before downfracture, the vertical height was established from the distance of the MCR to the incisal edge of the right upper central incisor (UCI). The vertical dimension was obtained with frequent measurements by use of calipers as desired during cephalometric tracing and model surgery. After rigid fixation, the vertical height was verified again. The UCI was traced from the postoperative cephalogram and predictive tracing onto a preoperative tracing. Repositioning of the maxilla and postsurgical movements of the UCI were registered at the horizontal and vertical planes. Comparison was made between the predicted maxillary position on the cephalometric tracing and the actual position, as well as between the planned maxillary position in model surgery and the actual position. RESULTS: The mean difference between the planned UCI position on predictive tracing and postsurgical position was 0.30 mm (SD, 0.21 mm; P > .05) in the vertical plane. The variation between the planned maxillary position in model surgery and the actual position was 0.37 mm (SD, 0.31 mm; P > .05) in the vertical plane. CONCLUSIONS: Good surgical accuracy in positioning the mobilized maxilla can be achieved by use of the MCR as an external reference point.

Manejo gengival em maxilas totalmente reconstruídas por enxertos e implantes / Gingival management in totally reconstructed maxilla by grafts and implants-case report

Os tecidos moles desempenham um importante papel para o resultado das cirurgias com implantes. Várias técnicas estão reportadas na literatura para aumentar a quantidade de gengiva ceratinizada ao redor dos implantes. Este artigo apresenta uma técnica de avanço do retalho palatal realizada durante a cirurgia de reabertura dos implantes em maxilas totalmente edêntulas reconstruídas com blocos de crista ilíaca.
