Many viral infections cause oral manifestations, including disorders in odontogenesis, resulting in dental malformations. In this review, based on current knowledge, we will discuss the likely dental and oral consequences of COVID-19. In this article, we review currently available data associated with vertical transmission of COVID-19 and odontogenesis, oral manifestations, and the impact of COVID-19 pandemic on a diagnosis of oral diseases. Owing to the severity of the pandemic, the population's anxiety and fear of becoming infected with COVID-19 may underestimate the signs and symptoms of serious illnesses, besides discourage patients from seeking health, medical or dental services to determine the diagnosis of oral lesions. Thus, the COVID-19 pandemic could be an additional and aggravating factor for the delay of serious illness diagnosis, such as oral squamous cell carcinoma resulting in higher morbidity and worse prognosis. Several changes and oral lesions have been described as oral manifestations of COVID-19, such as dysgeusia, oral ulcers, petechiae, reddish macules, desquamative gingivitis, among others. Besides, it can cause major systemic changes and predispose opportunistic infections. As with other viral infections, oral manifestations, including dental anomalies, can occur as a direct result of SARS-CoV-2 infection. However, further studies are needed to guide and clarify possible oral changes.

The ability to infiltrate various molecules and resins into dental enamel is highly desirable in dentistry, yet transporting materials into dental enamel is limited by the nanometric scale of their pores. Materials that cannot be infiltrated into enamel by diffusion/capillarity are often considered molecules with sizes above a critical threshold, which are often considered to be larger than the pores of enamel. We challenge this notion by reporting the use of electrokinetic flow to transport solutions with molecules with sizes above a critical threshold-namely, an aqueous solution with a high refractive index (Thoulet's solution) and a curable fluid resin infiltrant (without acid etching)-deep into the normal enamel layer. Volume infiltration by Thoulet's solution is increased by 5- to 6-fold, and resin infiltration depths as large as 600 to 2,000 µm were achieved, in contrast to ~10 µm resulting from diffusion/capillarity. Incubation with demineralization solution for 192 h resulted in significant demineralization at noninfiltrated histologic points but not at resin infiltrated. These results open new avenues for the transport of materials in dental enamel.

Este artigo tem como objetivo revisar a literatura acerca da importância da equipe multidisciplinar no cuidado e atenção à saúde bucal do idoso. Foram realizadas buscas bibliográficas nas seguintes bases de dados: Bireme, SciELO, LILACS, PubMed e MedLine utilizando os seguintes descritores: “Odontologia geriátrica”, “Assistência integral à saúde do idoso” e “Reabilitação bucal”, assim como os respectivos termos em inglês: “Geriatric dentistry”, “Comprehensive health care” e “Mouth reabilitation”. Foram incluídos artigos científicos em inglês e português, bem como documentos de entidades públicas nacionais e internacionais, publicados entre 2000 e 2016. Foram excluídas as teses, dissertações e estudos que não abordavam a temática principal da presente pesquisa. Como resultado, a partir da revisão de literatura realizada, verificou-se que os idosos fazem parte de um grupo populacional que apresenta, frequentemente, alterações fisiológicas e patológicas diversas, tanto relacionadas à saúde geral como à saúde bucal, podendo estar associadas ao uso crônico de medicamentos, aos hábitos de alimentação e higiene e à própria motivação do paciente. Portanto, conclui-se ser necessária uma abordagem multidisciplinar em todas as fases de atendimento do idoso, desde o diagnóstico precoce, assim como durante o planejamento e tratamento integrado, para contribuir na melhoria de sua qualidade de vida.

is study aimed to evaluate the efficacy of different concentrations of essential oils combined with calcium hydroxide against Enterococcus faecalis. irteen experimental groups were formed: NC (negative control); PC (positive control); GC (growth control); SC (sterilization control); RO (Rosmarinus officinalis); ROH (calcium hydroxide + RO); ZO (Zingiber officinale); ZOH (calcium hydroxide + ZO); AB (Citrus aurantium bergamia); ABH (calcium hydroxide + AB); CO (Copaifera officinalis); COH (calcium hydroxide + CO); DWH (calcium hydroxide and distilled water). After reconstitution of the E. faecalis strain, microdilution testing was performed to define the minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC). e data were tabulated in an Excel spreadsheet, and the MIC and MBC were calculated in accordance with the Bacteriological Analytical Handbook. MICs in the range of 0 to 100 mg/ml were only observed in the ROH group. e RO, ROH, AB, ZO, and ZOH presented absolute data for MBC. Bacterial growth was detected in the DWH group at all concentrations tested. e combination of the essential oils tested here with calcium hydroxide appears promising as an intracanal medication in endodontic treatment because of its effectiveness against Enterococcus faecalis. Essential oils are important in endodontic therapy since calcium hydroxide, the gold standard intracanal medication, is not effective against E. faecalis.

Aim: It was analyzed the efficacy of mouthwash and spray containing essential oil (EO) of Cinnamomum zeylanicum Blume for the treatment of oral candidiasis. Methods and results: A randomized, controlled, and blinded clinical trial was conducted with 36 individuals (probabilistic sample) with oral candidiasis who were divided into two treatment groups: C. zeylanicum (0.5 mg/mL), n = 18; nystatin (100,000IU/mL), n = 18. The efficacy of the products was evaluated by two parameters: (a) clinical evolution recorded by calibrated examiners (Kappa = 0.822) according to Newton's classification and (b) reduction of colonyforming units/mL. Mycological and clinical parameters were analyzed before and at 15 days after treatment. Clinical examination of the mucosa showed that C. zeylanicum (p < 0.0339) and nystatin (p < .0139) had efficacy, resulting in a reduction of signs and symptoms (Mann-Whitney test). Mycological analysis showed that C. zeylanicum caused a reduction of 61% and 33% of Candida spp., isolates oral mucosa and dentures, respectively. Candida tropicalis strains were eliminated after C. zeylanicum, in both sites. The participants reported a pleasant taste and few product-related complaints. Conclusion: C. zeylanicum EO and nystatin exhibited clinical efficacy, accordingto the Newton classification, and reducing in Candida spp. The clinical trial has been registered (Registration number: NBR-33s6 × 5, ensaiosclinicos.gov.br).
