ABSTRACT

ABSTRACT Objective To evaluate knowledge and attitudes towards biosafety recommendations during the COVID-19 pandemic at a Brazilian dental school. Material and Methods A cross-sectional study was performed in 2020 with the clinical staff of a Brazilian dental school. The whole clinical staff was sent pre-tested self-administered online questionnaires about knowledge and attitudes towards the recommendations for biosafety in dental settings in the context of the COVID-19 pandemic. Descriptive statistical analyses were carried out for proportion calculation. Results Disposable head covering caps, isolation gowns, and gloves were the most frequently reported personal protective equipment (PPE). The rates ranged from 52.9% to 88.5% for N95 respirators, from 68.6% to 92.6% for face shields, from 47.4% to 67.5% for conventional eye protection shields, and 45.1% to 77.4% for eye protection with solid side shields. Chlorhexidine gluconate was the most frequent mouthwash indicated before clinical dental care. The percentage of agreement to provide clinical care to patients with suspected COVID-19 varied from 23.5% to 50.0%. The percentage of respondents who agreed that bioaerosol-generating procedures should be avoided was higher than 74.5%. Less than 50% knew the correct sequence for doffing of PPE. Conclusion This study revealed important gaps in knowledge and attitudes towards prevention and control measures against infection in dental environments in the context of COVID-19, indicating the need for improvements.

Foram analisados os documentos publicados pelo Ministério da Educação (MEC), Conselho Federal de Odontologia (CFO) e Associação Brasileira de EnsinoOdontológico (ABENO).Os documentos foram coletados nos websitesdas entidades selecionadas. O tratamento dos dados qualitativos foi realizado por meio da análise de conteúdo temática, sendo comparadas qualitativamente as diferentes publicações, identificando-se pontos convergentes, divergentes ou ausentes entre os documentos.Combase na problematização do objeto em questão, foram emitidas sugestões a partir das fragilidades e potencialidades relacionadas à execução das recomendações. Os dados foram distribuídos nas unidades de análise "sala de espera", "clínica" e "laboratório". As principais potencialidades foram relacionadas à diminuição do risco biológico de transmissão de patógenos e à adequação de espaços físicos em ambientes mais ergonômicos de aprendizagem. Quanto às fragilidades, aponta-se o aumento de custos para discentes e instituições e a redução no número de atendimentos. Existem desafios a serem considerados em relação ao cumprimento dos novos protocolos de biossegurança no retorno das atividades práticas nos cursos deOdontologia durante a pandemia da COVID-19 (AU).


This study presents challenges related to the fulfillment of the new biosafety protocols aiming to return the face-to-face activities in higher education institutions in Dentistry considering the pandemic scenario of COVID-19. It was a qualitative, exploratory study, anchored in the technique of documentary research. We analyzed documents published by the Ministry of Education(MEC), the Federal Council of Dentistry (FCD) and the Brazilian Association for Dental Education (BADE). The documents were collected on websites of the selected entities. The treatment of qualitative data obtained was carried out by thematic content analysisto compare qualitatively the different documents by identifying convergent, divergent or absent points between them. From the problematization of the object under study, suggestions were made based on the weaknesses and potentialities related to the execution of the recommendations. Data were distributed in the analysis units "waiting room", "clinic" and "laboratory". The main potentialities were related to the reduction of the biological risk of transmission of pathogens and the adaptation of physicalspaces in more ergonomic learning environments. As for the weaknesses, there are increased costs for students and institutions and reduced number of visits. There are challenges to be considered to comply with the new biosafety protocols in the return of practical activities in Dentistry Courses during the COVID-19 pandemic (AU).

ABSTRACT

Objective:To investigate the clinical application value of montmorillonite powder combined with Kangfuxin liquid in the treatment of stomatitis complicated by oral ulcer. Methods:A total of 124 patients with stomatitis complicated by oral ulcer who received treatment in Zhoushan Women and Children Hospital, China between January 2019 and October 2020 were included in this study. They were randomly assigned to receive treatment either with montmorillonite powder alone (control group, n = 62) or montmorillonite powder and Kangfuxin liquid (observation group, n = 62). Visual Analogue Scale score before and after treatment, duration of ulcer pain and wound recovery time, curative effect and adverse reactions were compared between the two groups. Results:After treatment, Visual Analogue Scale score in each group was significantly decreased compared with before treatment ( t = 5.862, 8.223, both P < 0.05). After treatment, Visual Analogue Scale score in the observation group was significantly lower than that in the control group [(0.72 ± 0.23) points vs. (1.22 ± 0.47) points, t = 2.667, P < 0.05]. The time to ulcer pain relief and the time to wound recovery in the observation group were significantly shorter than those in the control group ( t = 3.467, 2.667, both P < 0.05). Effective rate in the observation group was significantly higher than that in the control group [96.77% (60/62) vs. 85.48% (53/62), χ2 = 4.888, P < 0.05]. There were no adverse reactions in each group. Conclusion:Combined application of montmorillonite powder and Kangfuxin liquid for the treatment of stomatitis complicated by oral ulcer can effectively mitigate wound pain, accelerate wound healing, and improve the quality of life. This study is of significant innovation and science. Therefore, the treatment method used in this study is worthy of clinical promotion.

ABSTRACT

Abstract: The objective of this review is to identify preventive measures for COVID-19 to safeguard dental professionals providing prosthodontic dental care. Electronic searches were performed in PubMed, Scopus, and Cochrane databases using the following descriptors and/or words: "COVID-19," "SARS-CoV-2," "Dental practice," "Prosthodontics," and "Dental infection control." Prosthodontists are at high risk for exposure to the novel coronavirus through aerosols and possibly contaminated surfaces and indirect contact with dental laboratories and dental technicians through impressions, dental stone casts, and fixed and removable prosthetic appliances. Therefore, preventive measures should be implemented, including performing emergency treatments only, rescheduling patients with suspected disease, disinfecting surfaces and prosthodontic materials with biocidal substances, and using protective equipment such as N95 masks, disposable gowns, and face-shields.

ABSTRACT

ABSTRACT Objective: To evaluate the dentists' knowledge about biosafety considering the SARS-CoV-2 and the risks of increasing the COVID-19 outbreak by dental practices during the pandemic in Brazil. Material and Methods: A cross-sectional study was performed by internet-based snowball sampling technique. A questionnaire with questions about different content was applied, and then analyzed the following two parameters: participants' Brazilian region and professional's specialty. Results: A total of 413 e-questionnaires from all Brazilian regions were considered valid. There were no significant differences among biosafety measures adopted by participants from different Brazilian regions (p≥0.05), except for those from North region, which have applied less previous oral antisepsis, temperature screening, and specific anamnesis tracking COVID-19 symptoms (p<0.05). The unique use of N95 mask was positively associated with North region (p<0.05). Expert participants of Groups 2 (oral surgery and correlate areas) and 4 (orthodontics, oral radiology and facial jaw orthopedics) were more updated than other ones (p<0.05). Conclusion: The biosafety protocols applied by participants were not adequate for the epidemiologic status of COVID-19 in each region of Brazil, from 13th May to 17th June 2020. Specialties linked to microbiology area or structured social networks have better applied preventive measures for COVID-19.

ABSTRACT

ABSTRACT Objective: To identify the epidemiological profile of accidents with biological material occurring in the dental clinic of a university in the southern region of the country. Methods: This is a descriptive, cross-sectional, retrospective study, which analyzed the reports of the Epidemiological Surveillance (SINAN) that occurred between March 2013 and December 2016. We analyzed the demographic variables and data related to the notification of accidents with biological material in the SINAN file, such as: age, sex, race, occupation (student, teacher, oral health technician, residents), time and place of occurrence of the accident, agent causing the perforation, total or partial use of PPE (personal protective equipment) at the time of accident, contact with organic material, contact agent and up-to-date vaccination against hepatitis B and treatment withdrawal. The data obtained were analyzed in EpiInfo Software. Statistical analysis included descriptive and inferential analysis, with significance level of p?0.05 and confidence interval (CI) of 95%. Results: In total there were 55 reports of accidents with piercing-cutting materials, of which 12 were men (21.82%) and 43 were women (78.18%). The mean age of the sample population was 24.2 (± 6.3) years. Regarding the occupation, 80% (n = 44) were undergraduate students, 12.72% were residents, 5.45%, teachers and 1.82%, oral health technicians. The majority (61.8%) were perforated during the dental procedure, 21.82% during material washing and 16.36% during surgery, but 20% claimed that they did not use any personal protective equipment. Regarding the organic material, there was a high prevalence of contact with blood, 70.9%, the needle was the main agent (n = 26; 47.3%). Still, 3.7% stated that they were not vaccinated against hepatitis B. In the bivariate analysis, the site of the accident was associated with the use of personal protective equipment (p = 0.01). Conclusion: The results showed that the number of incidents is high and can be attributed to several factors, such as lack of experience of students and the non-use of personal protective equipment. As a result, it is necessary to establish a permanent education program focused on education and accident prevention strategies to minimize these problems.


RESUMO Objetivo: Identificar o perfil epidemiológico dos acidentes com material biológico ocorridos na clínica odontológica de uma universidade na região sul do país Métodos: Foi realizado um estudo descritivo, transversal, retrospectivo, analisando as notificações da Vigilância Epidemiológica (SINAN) ocorridas entre março de 2013 a dezembro de 2016. Foram analisadas as variáveis demográficas e os dados referentes a notificação de acidentes com material biológico contidas na ficha do SINAN, tais como: idade, sexo, raça, ocupação (estudante, professor, técnico em saúde bucal, residentes), momento e local da ocorrência do acidente, agente causador da perfuração, uso total ou parcial de EPI no momento do acidente, contato com material orgânico, agente do contato e vacinação em dia contra hepatite B e abandono do tratamento. Os dados obtidos foram analisados pelo Software EpiInfo. A análise estatística incluiu a análise descritiva e inferencial, com nível de significância de p?0,05 e intervalo de confiança (IC) de 95%. Resultados: No total houve 55 notificações de acidentes com materiais pérfuro-cortantes, sendo doze homens (21,82%) e 43 mulheres (78,18%). A idade média da população amostral era de 24,2 (±6,3) anos. Quanto à ocupação, 80% (n=44) eram estudantes de graduação, 12,72% residentes, 5,45% professores e 1,82% técnico em saúde bucal. A maioria (61,8%) se perfurou durante o procedimento odontológico, 21,82% durante a lavagem dos materiais e 16,36% durante uma cirurgia, porém 20% alegaram que não utilizavam o equipamento de proteção individual. Em relação ao material orgânico, houve grande prevalência do contato com o sangue 70,9%, sendo a agulha o principal agente (n=26; 47,3%). Ainda, 3,7% afirmaram não estavam vacinados contra hepatite B. Na análise bivariada, o local do acidente esteve associado com o uso do equipamento de proteção individual (p=0,01). Conclusão: Os resultados mostraram que o número de incidentes é elevado e podem ser atribuídos a diversos fatores, como a falta de experiência dos estudantes e a não utilização de equipamentos de proteção individual. Em decorrência disso, é necessário estabelecer um programa de educação permanente focado em estratégias de educação e prevenção de acidentes para minimizar esses agravos.

ABSTRACT

PURPOSE: To evaluate the effect of surgical treatment of ligature-induced peri-implantitis in dogs using fractal analysis. Also, the capabilities of fractal analysis as bone analysis techniques were compared with those of histomorphometric analysis. MATERIALS AND METHODS: A total of 24 implants were inserted in 6 dogs. After a 3-months, experimental periimplantitis characterized by a bone loss of about 3 mm was established by inducing with wires. Surgical treatment involving flap procedure, debridement of implants surface with chlorhexidine and saline (group 1), guided bone regeneration (GBR) with absorbable collagen membrane and mineralized bone graft (group 2), and CO2 laser application with GBR (group 3) were performed. After animals were sacrificed in 8 and 16 weeks respectively, bone sections including implants were made. Fractal dimensions were calculated by box-counting method on the skeletonized images, made from each region of interest, including five screws at medial and distal aspects of implant, were selected. RESULTS: Statistically significant differences in the fractal dimensions between the group 1 (0.9340+/-0.0126) and group 3 (0.9783+/-0.0118) at 16 weeks were found (P<0.05). The fractal dimension was statistically significant different between 8 (0.9395+/-0.0283) and 16 weeks in group 3 (P<0.05). These results were similar with the result of the evaluation of new bone formation in histomorphometric analysis. CONCLUSION: Treatment of experimental peri-implantitis by using CO2 laser with GBR is more useful than other treatments in the formation of new bone and also the tendency of fractal dimension to increase relative to healing time may be a useful means of evaluating.

ABSTRACT

Este estudo objetivou avaliar a eficácia do uso da estufa de Pasteur, como equipamento esterilizante, em consultórios odontológicos, por meio de monitoramento biológico. Para esta avaliação foram consideradas: adequação no carregamento dos materiais no equipamento, tempo/temperatura utilizados e manutenção preventiva da estufa. Os dados foram coletados em 101 consultórios odontológicos, no Distrito Central de Goiânia-GO, Brasil, por meio de observação, entrevista e realização de teste com indicador biológico. Os resultados demonstraram não-padronização de algumas condutas preconizadas pelo Ministério da Saúde (MS), para esterilização dos artigos em estufa, e positividade do teste biológico em 46 (45,5 por cento) dos ciclos testados. Os fatores intervenientes, com maior significância, relativos às falhas da esterilização foram: ausência do termômetro acessório para o controle da temperatura dos ciclos e a inobservância das relações tempo/temperatura recomendados para o ciclo de esterilização, por calor seco.


This study was aimed at assessing the efficacy of the use of the Pasteur oven as sterilization equipment in dental offices through biological monitoring. For this assessment were taken into account how adequately the material is loaded into the equipment; time/temperature used; and preventive maintenance of the oven. The data were collected in 101 dental offices in the Central District of Goiânia, in the State of Goiás, through observation, interviews and performance of tests with biological indicator. The results showed a lack of standardization of some of the procedures recommended by the Ministry of Health for sterilization of items in the oven, and positive results of the biological test in 46 (45.5 percent) of the tested cycles. The intervening factors with most significance regarding sterilization problems were: absence of an accessory thermometer to control the cycles' temperature and non-observance of the time/temperature relations recommended for the sterilization cycle through dry heat.

ABSTRACT

Objective To observe the antibacterial activity of artificial antimicrobial peptides (AMPs) to Blastomyces albicans, E. coli and Staphylococcus aureus in oral infection in vitro. Methods The AMPs were dissolved into PBS or sterilized saliva, then the inhibi-tion of different concentration AMPs to E. coil was evaluated by tube testing. The inhibition effect of different concentration of AMPs to Staph-ylococcus aureus and Blastomyces albicans were evaluated by antibiotic-susceptive test paper. Results When the concentration of AMPs added to broth of E. coli is from 150μmol/L to 300μmol/L , the bacterium count is 0 while the number in control is 6700 ~ 9200cfu/ml. At 100μg/tablet AMPs, the diameter of inhibitor zones of Staphylococcus aureus and Blastomyces albicans are 13mm and 11 mm. At 300μg/ tablet, the diameter are 16 mm and 17mm. AMPs dissolved in PBS and saliva have similar antimicrobial activity. Gonclusions The AMPs is effective to prevent Blastomyces albicans, E. coli and Staphylococcus aurcus in oral infection in vitro.
