Resumo O objetivo deste estudo foi avaliar os aspectos comportamentais e as crenças da população cearense frente à pandemia de COVID-19. Foi realizado um questionário “on line” sobre aspectos sociodemográficos e crenças relacionados à pandemia. Foram calculadas frequências absoluta e relativa, a associação entre variáveis foi realizada com Qui-quadrado e o nível de significância foi de 5%. A amostra final contou com 2.259 participantes e foi observada associação entre o gênero feminino e se perceber com um alto risco de contaminação (p = 0,044) e o gênero masculino com a não realização voluntária da quarentena (p < 0,001). Pessoas com 80 anos ou mais realizaram quarentena parcialmente devido ao fluxo de pessoas em casa (p < 0,001). Os participantes com o ensino fundamental se perceberam com um risco menor de contaminação que aqueles com grau de escolaridade mais elevado (p < 0,001). Neste grupo estão as pessoas que menos fizeram quarentena voluntária (p < 0,001). Os participantes que moram no interior do estado, tiveram menos contato direto com alguém testado positivamente para o coronavírus (p = 0,031) e estão menos reclusos (p < 0,001). É possível concluir que a abordagem frente à pandemia de COVID-19 varia de acordo com aspectos sociais, como gênero, idade, escolaridade e local de residência, assim como o sistema de crenças da população do estado do Ceará.

Objective: This systematic review aimed to determine whether the use of photobiomodulation (PBM) with low-level laser therapy prevents tooth sensitivity induced by in-office tooth bleaching with hydrogen. Methods: Placebo-controlled clinical trials were included to evaluate the efficacy of PBM with low-level laser therapy in the prevention of tooth sensitivity after in-office tooth bleaching. Searches were conducted on the Medline database via PubMed, Scopus, Web of Science, EBSCO, SciELO, LILACS, Cochrane, DOSS, and Google Scholar until July 2020, and fixed-effects meta-analysis was performed for tooth sensitivity [standardized mean differences (MDs)] and color changes (MDs). Results: Five studies were included in this systematic review and meta-analysis, with a total of 288 patients, 123 patients in the PBM group and 165 patients in the placebo group. In the meta-analysis, despite high heterogeneity, PBM significantly reduced the tooth sensitivity after the first [p < 0.001; Cohen's d = −0.32, 95% confidence interval (CI) = −0.46 to −0.18], second (p < 0.001; Cohen's d = −0.30, 95% CI = −0.46 to −0.15), and third (p < 0.001; Cohen's d = −0.82, 95% CI = −1.06 to −0.58) sessions of in-office tooth bleaching, without impairing the ΔE (p = 0.300). Conclusions: The results of this systematic review and meta-analysis suggest that PBM significantly prevents pain-related symptoms after the first three weekly sessions of in-office tooth bleaching with hydrogen.

Universal adhesive systems used for restorative clinical procedures are like orthodontics and may be a viable option. This study evaluated the effectiveness of universal adhesive systems in enhancing the durability of the shear bond strength (SBS) and adhesive remnant index (ARI) of orthodontic brackets to enamel. 100 bovine incisors were divided into five groups (n=20), according to the applied adhesive systems: Primer Transbond XT; Ambar; Ambar Universal; Single Bond Universal; Adper Single Bond 2. Bracket from each tooth were submitted to SBS test after 24 hours, and 12 months later. The amount of remaining adhesive was evaluated through ARI. After 24 hours, there was no difference in BS between the control and the other groups (p>0.05). However, there were difference between TOTALETCHING1 group and the Ambar Universal (p=0.015) and Single Bond Universal groups (p=0.011). After 12 months, Primer Transbond XT, Ambar, Ambar Universal and Adper Single Bond 2 showed no differences in the SBS (p>0.05). Nonetheless, Single Bond Universal presented superior result when compared to Primer Transbond XT (p=0.046) and Ambar (p=0.011) groups. The SBS of all groups reduced significantly after 12 months (p<0.05). There was no difference between ARI scores in each individually assessed group (p>0.05), for both periods. Following 24 hours, a difference was observed between the groups (p=0.043), fact that didn’t occur after 12 months (p=0.109). Adhesive systems, such as Ambar Universal and Single Bond Universal are efficient in bonding orthodontic brackets to enamel when associated with Transbond XT adhesive paste. Key words:Bond strength; Primer Transbond XT, orthodontic brackets, adhesive systems.

This study evaluated the repercussions of coronavirus disease-2019 (COVID-19) in Brazilian dentists' personal and professional routines. Brazilian dentists were invited to participate in an online survey with questions pertaining to COVID-19 and its repercussions in dental practice. Sample calculation was performed using the Survey Monkey software (www.surveymonkey.com). The minimum sample required to obtain a 95% confidence level (CI) and 1% margin of error was 4,214. The eligibility criteria were dental professionals, of any gender and age, who were working in dentistry in a public, private, or university environment, regardless of the time of experience in the profession, and agreed to participate in the study. The survey was structured such that all the Brazilian regions were touched upon, thereby aiming at covering and collecting the representative data of the region. Responses were analyzed using chi-square tests, t-tests, and one-way analysis of variance, with statistical significance at p <0.05. A total of 15,813 dentists responded to the survey, representing all Brazilian regions. Complete social isolation was practiced by 96.21% of the respondents, and approximately 25% knew someone who had contracted COVID-19. Public health specialists were the most likely to provide emergency treatment (71.90%, p <0.001). In the Northeast region, 79.80% of respondents agreed that conventional personal protective equipment (PPE) was insufficient to prevent COVID-19 transmission, and 79.10% considered their biosecurity measures insufficient (p <0.001). In the North region, most dentists continued to perform elective dental procedures (p <0.001). It is possible to conclude that Brazilian dentists demonstrated high knowledge of COVID-19's main symptoms and the risks of transmission through dental procedures. Most respondents practiced social isolation, although some did continue to provide emergency dental care. To improve infection control in dental care settings against COVID-19, it is necessary to educate and raise awareness among professionals.
