Abstract Objective: To investigate the usefulness, reliability, quality, and content of Portuguese-language YouTube videos on COVID-19. Material and Methods: Three keywords selected on Google Trends were searched on YouTube, and the 60 first videos listed with each term were analyzed. Two calibrated researchers evaluated the reliability (DISCERN Modified Scale), the quality (Global Quality Score - GQS), and the usefulness of videos for the users (COVID-19 Specific Score - CSS). The number of views, likes, and engagement were also analyzed. The data were evaluated by the Mann-Whitney test and Spearman correlation (α=5%). Results: 59 videos were included. The average scores of quality, reliability, and usefulness were 3.0 (±1.1), 3.2 (± 0.8), and 1.5 (± 0.9), respectively. Two-thirds of the videos (64.4%) had low/moderate quality, and the majority (76.2%) were about signs and symptoms. The numbers of views (p=0.005), likes (p=0.006), and engagement (p=0.014) were significantly higher in moderate/good quality videos. The number of comments (p=0.007), duration of videos (p=0.004), and the DISCERN score (p<0.001) were significantly higher in videos made by health professionals. The general quality of the videos was positively correlated to the CSS scores, number of views, likes, and engagement (p<0.05). Conclusion: Most videos had moderate quality and reliability and low usefulness for the users. Objective Portugueselanguage Portuguese language COVID19.

Abstract This study aimed to develop and validate a self-administered questionnaire in Brazilian Portuguese to verify the level of knowledge of orthodontists in the care of pregnant, lactating, and postmenopausal women, named “Considerations on Orthodontic Treatment during Pregnancy, Lactation, and Postmenopausal Periods.” The development and validation of the questionnaire consisted of the following steps: a) item generation; b) item reduction; c) questionnaire design; and d) validity and reliability tests in a cross-sectional study with 258 orthodontists working in the field from different Brazilian states. A total of 60 orthodontists participated in test-retest over a mean period of 45 days. The preliminary questionnaire consisted of a total of 60 questions. After item reduction, 40 questions were selected for the final version of the questionnaire, with eight questions about pregnant women; six about lactating women; 18 about postmenopausal women, and eight about general knowledge in dentistry. Each item had three response options in the Likert scale format. Face and content validity analysis, reliability assessment through internal consistency (Cronbach’s alpha and McDonald’s omega), and test-retest reliability through the intraclass correlation coefficient (ICC) and Spearman’s correlation coefficient were performed. Face and content validity indicated that the questionnaire was considered valid, objective, and easily understandable. The questionnaire had good internal consistency (Cronbach’s alpha = 0.77; McDonald’s omega = 0.78) and good test-retest reliability (ICC = 0.71; Spearman’s correlation coefficient = 0.51). The questionnaire was considered valid and reliable to assess the level of knowledge of orthodontists in the care of pregnant, lactating, and postmenopausal women. selfadministered self administered women Considerations Pregnancy Lactation Periods.

ABSTRACT Objective: To assess changes in oral health-related behavior and oral health status in Brazilian children in early childhood perceived by their parents/caregivers during social isolation caused by COVID-19. Material and Methods: A cross-sectional study with parents/caregivers of children in southeastern Brazil aged 0-5 years who responded to an online questionnaire about sociodemographic data, dietary changes, oral hygiene, and oral health status of children during the COVID-19 pandemic. Results: Of the 119 parents/caregivers, 54.60% did not observe any changes in eating habits, and 81.50% maintained their children's oral hygiene. Associations were observed between the impact of the pandemic on the family income and changes in eating habits (p=0.02) and between lower family income and dental caries perceived by parents/caregivers (p=0.05). Z tests with Bonferroni correction showed that families with drastic income reduction were more likely to consume lower-cost foods (62.50%) than families with no impact or slight reduction on family income. Parents/caregivers did not identify dental caries (89.10%), toothache (92.40%), and dental trauma (92.40%) in their children. Conclusion: Parents/caregivers of children in southeastern Brazil aged 0-5 years observed behavioral changes in the dietary habits of families whose income was impacted by the pandemic, and their perception of dental caries was significantly associated with family income.

Abstract The aim of this study was to identify and describe the characteristics of coronavirus (COVID-19)-disease related dental research in Brazil presented at the 38th Annual Meeting of the Brazilian Division of the International Association for Dental Research (SBPqO). A search was carried out in the proceedings of the meeting to retrieve all abstracts. Those containing the term “COVID-19” in titles, abstracts, or keywords, and/or those of which the scope approached a COVID-19-related topic were included. The variables extracted from abstracts were: presenter category, field of study, design, data collection method, population, affiliation, and authors’ gender. Descriptive and inferential statistics were used, with a significance level of α = 0.05. The search retrieved 185 abstracts, 5 did not meet study eligibility criteria and were excluded. COVID-19-related research was presented by either aspiring/associate members (67.8%) or beginner members (32.2%). Data collection methods were predominantly digitally mediated (65%), followed by secondary data use (25%), and in-person data collection (7.2%). Irrespective of the role of authorship, there were a ratio of two female authors to each male. Among the last authors, the ratio was three females to each male. Female lead authors more frequently came from the Southeast region (71.8%; p = 0.470). There was an association between presenter category and study design (p = 0.012), clinical and epidemiological studies were more concentrated among experienced presenters. In conclusion, female dental researchers affiliated to southeastern institutions approached the topic of pandemic more frequently than male colleagues. The use of digital technology for data collection may have long-lasting impacts on the teaching and publication of dental research. COVID19disease COVIDdisease COVID 19 disease th SBPqO. SBPqO .

ABSTRACT Objective: To evaluate the prevalence of dental caries in children from 18 months to 5 years of age in eastern (near urban centers) and western (far from urban centers) Parakanã, verify the influence of proximity to non-indigenous cultures, and compare with other ethnicities and non-indigenous. Material and Methods: The universe of children was examined by one researcher in a cross-sectional study. Descriptive analysis and the Mann-Whitney test (p<0.05) were performed. Results: It was observed that 68.8% (N = 53) of children from 18 to 36 months of age presented dmft = 0 (without caries), while 12.5% (N = 6) of children of five years of age presented this condition. For children between 18 and 36 months, the average dmft values were 0.74 (SD=1.91) for eastern children and 1.25 (SD=1.65) for western children. At five years of age, the average dmft values were 4.35 (SD=3.29) and 3.75 (SD=2.05) for eastern and western, respectively. Mann-Whitney test (p<0.05) showed no difference between East and Western children. When compared with non-indigenous Brazilian children, the values behaved similarly. Conclusion: Knowledge of the epidemiological profile of dental caries in Indigenous Parakanã children is relevant both in planning oral health actions for this population and for aggregating information, which is still scarce for Indigenous.

Abstract The present study aimed to perform the cross-cultural adaptation of the Digital Health Literacy Instrument (DHLI) for native Brazilian Portuguese-speaking adolescents (DHLI-BrA). Cross-cultural adaptation consisted of the following steps: translation, assessment, and adjustments by the expert committee to ensure cultural equivalence; back-translation, and synthesis of back-translations. Cognitive testing was then performed in a pretest with adolescents using cognitive interviews with probing questions on the item's understanding interpretation and response options. Cronbach’s alpha coefficient and McDonald’s omega were used to estimate the instrument’s reliability. Forty-two Brazilian adolescents participated in the study (mean age: 16.0 ± 2.0 years; range: 13 to 19 years). Items that were difficult to understand were adapted to the context of Brazilian adolescents. Cronbach’s alpha coefficient and McDonald’s omega for the 21 items of the DHLI-BrA were, respectively, 0.79 and 0.80. Cronbach’s alpha coefficient for the subscales of the self-report instrument was 0.53-0.79 (range), demonstrating good reliability in the total instrument and moderate reliability in the subscales. This study provides the cross-cultural adapted version of the Digital Health Literacy Instrument (DHLI), which is an instrument for measuring digital Health literacy, for use in Brazilian adolescents (DHLI-BrA). crosscultural cross DHLI (DHLI Portuguesespeaking Portuguese speaking DHLIBrA.

Abstract The aims of this study were to perform an exploratory analysis of probable awake (AB) and sleep bruxism (SB) prevalence using of different diagnosis criteria based on the International Consensus; evaluate the associations between self-report and clinical signs/symptoms in adolescents. Participated in this cross-sectional study 403 adolescents aged 12- to 19-years-old enrolled in public and private schools from Belo Horizonte, Brazil. Parents/caregivers answered a questionnaire about sociodemographic status and adolescents’ health status. Adolescents answered a questionnaire evaluating AB (e.g., grinding and clenching) and SB (e.g., grinding, bracing, and thrusting) activities and frequent headaches. A clinical examination was performed on adolescents to evaluate bruxism clinical signs/symptoms (pain upon palpation on masseter and temporal, linea alba, indentation on the tongue and attrition wear severity). Descriptive statistics and Pearson’s Qui-square test were performed (P≤0.05). Adolescents mean age was 14.3±1.5 years, and 58.1% were female. Self-report of SB was identified in 31% of participants and self-report of AB in 51.6%. Almost all adolescents (99%) presented at least one tooth with attrition wear (98.5% on enamel and 0.5% on dentin), with a mean number of 12.4±5.7 teeth. Depending on the diagnosis criteria, the prevalence of probable SB and AB varied from 0- 99% and 0.2- 99%, respectively. A high inconsistency was found for the prevalence of probable AB and SB in adolescents, which were influenced by the different clinical sings/symptoms used as diagnosis criteria. Frequent headaches and pain upon palpation on masseter and temporal muscle were associated to self-report of AB and SB among adolescents.

Abstract The Patient Satisfaction Questionnaire (PSQ) is a self-administered instrument to assess adolescent patients' satisfaction with orthodontic treatment. A pre-existing North American instrument was further explored in the Netherlands. Semantic equivalence is part of cross-cultural adaptation and is necessary to achieve a valid and reliable instrument for a specific culture. The present study aimed to evaluate the semantic equivalence of the items, subscales, and overall PSQ between the original English version and the Brazilian Portuguese language version (B-PSQ). The PSQ has 58 items, distributed across 6 subscales: doctor-patient relationship, situational aspects of the clinic, dentofacial improvement, psychosocial improvement, dental function, and a residual category. Semantic equivalence was evaluated according to the following methods: (1) independent translations to Portuguese by two translators, both native in Brazilian Portuguese and fluent in English; (2) an expert committee drafted the first summarized version in Portuguese; (3) two independent back-translations into English by two native English-speaking translators fluent in Portuguese; (4) committee review; (5) committee drafted a summarized version of the back-translations; (6) expert committee drafted the second summarized version in Portuguese; (7) pre-test of the instrument using individual semi-structured interviews with 10 adolescents; (8) review and final version of the B-PSQ. Semantic equivalence between the original and the Brazilian versions of the questionnaire was achieved through diligent and rigorous methods, with effective translation and expert evaluations, incorporating the opinions of the target population.

ABSTRACT Objective: The purpose of the present in vitro study was to evaluate the efficiency of three different instruments in the root canals of artificial primary molars as well as the quality of the fillings. Methods: Sixty artificial primary molars were divided into three groups of 20 teeth. Each group was submitted to a different technique: Group 1 - conventional manual technique using Kerr files; Group 2 - manual technique with nickel-titanium files; Group 3 - NiTi rotary technique. The root canals were filled with calcium hydroxide paste. Aspects such as homogeneity of the fillings, taper and flowability of the preparations were considered comparatively to assess the quality of the instrumentations. The non-parametric Kruskal-Wallis and Mann-Whitney tests were used to compare the efficiency of the preparation of the root canal considering the preparation times of them. Results: All three techniques were equally effective at shaping the root canals of primary teeth. The working time was shorter with the rotary instrument (p=0.000). In the pairwise comparisons, working time was shorter with the rotary instrument compared to the manual techniques with steel files (p=0.000) and NiTi files (p=0.000). Comparing the manual techniques, the working time was shorter with NiTi files compared to steel files (p=0.011). Moreover, less variability in the preparation time was found when the rotary instrument was used. Conclusions: The mechanized rotary method led to a shorter operating time in comparison to the manual techniques and is therefore a preferable option for the preparation of the root canals of primary teeth.

RESUMO Objetivo: Avaliar a eficiência de três instrumentos diferentes nos canais radiculares de molares decíduos artificiais, bem como a qualidade das obturações. Métodos: Sessenta molares decíduos artificiais foram divididos em três grupos de 20 dentes. Cada grupo foi submetido a uma técnica diferente: Grupo 1 - técnica manual convencional com limas Kerr; Grupo 2 - técnica manual com limas de níquel-titânio; Grupo 3 - Técnica rotatória de níquel-titânio. Os canais radiculares foram preenchidos com pasta de hidróxido de cálcio. Aspectos como homogeneidade das obturações, conicidade e fluidez das preparações foram considerados comparativamente para avaliar a qualidade das instrumentações. Os testes não paramétricos de Kruskal-Wallis e Mann-Whitney foram utilizados para comparar a eficiência do preparo do canal radicular considerando os tempos de preparo dos mesmos. Resultados: Todas as três técnicas foram igualmente eficazes na modelagem dos canais radiculares. O tempo de trabalho foi menor com o instrumento rotatório (p=0,000). Nas comparações pareadas, o tempo de trabalho foi menor com o instrumento rotatório em comparação com as técnicas manuais com limas de aço (p=0,000) e limas de NiTi (p=0,000). Comparando as técnicas manuais, o tempo de trabalho foi menor com as limas de NiTi em comparação com as limas de aço (p=0,011). Além disso, foi encontrada menor variabilidade no tempo de preparo quando o instrumento rotatório foi utilizado. Conclusão: O método rotatório levou um menor tempo operatório em comparação com as técnicas manuais e, portanto, é uma opção preferível para o preparo dos canais radiculares de dentes decíduos.

ABSTRACT Background Sleep bruxism (BS) is defined as involuntary jaw movements characterized by grinding and clenching teeth. Objective To verify the association between chronotype, sleep quality, and self-reporting of BS in dental students. Method A cross-sectional study was conducted with 214 undergraduate dental students at a public university in northeast Brazil. The participants answered the Munich Chronotype Questionnaire for the identification of chronotype and another questionnaire regarding daily aspects to collect information about sleep quality, self-reported sleep bruxism, the use of sleeping pills, snoring, concentration during daily activities and energy upon waking. Results The prevalence of self-reported sleep bruxism was 11.0%. In the final model, the eveningness chronotype (OR = 23.00; 95% CI: 2.36-223.84, p = 0.007), habitual snoring (OR = 3.12; 95% CI: 1.31-7.39, p = 0.01) and low energy upon waking in the morning (OR = 2.37; 95% CI: 1.96-5.58, p = 0.040) were associated with self-reported sleep bruxism. Conclusion The evening chronotype, presence of snoring, and low energy when waking up in the morning influenced self-reporting of sleep bruxism among undergraduate dental students.

Abstract The aim of this multicenter study was to explore the early-life sugar consumption and dietary practices in Latin America as well as to investigate the association between breastfeeding duration and the age at which foods and beverages with added sugars are introduced. A cross-sectional study was conducted with 805 1- to 3-year-old children from 10 Latin American countries, as a complementary study to the Research Observatory for Dental Caries of the Latin American Region (OICAL). A Food Frequency Questionnaire previously tested in different countries was applied to children’s mothers and data on breastfeeding and age at introduction of sugary foods and beverages was collected. Statistical analysis included the Kruskal-Wallis test and Poisson regression with robust variance, with the calculation of crude and adjusted mean ratios (MR) and 95% of confidence intervals (CI). The average age at introduction of sugary foods and beverages was 10.1 months (95%CI 9.7–10.4) and 9.6 (95%CI 9.2–9.9) months, respectively, with a significant variation between countries (p < 0.001). The average daily frequency of sugary foods-beverages was 3.3 times per day (95%CI 3.1–3.5) and varied significantly between countries (p = 0.004). Breastfeeding duration of over six months was associated with an increase in the age of introduction of sweet drinks (16%; MR 1.16; 95%CI 1.05–1.28) and foods (21%; MR 1.21; 95%CI 1.10–1.33). In conclusion, most children from vulnerable settings in Latin America start consuming sugary products in the first year of life and a high frequency of consumption was reported through early childhood. Additionally, breastfeeding contributes to a delay in the introduction of sugary products. earlylife introduced crosssectional cross sectional 80 1 3yearold yearold 3 old OICAL. OICAL .

Abstract The aim of this paper was to present a summary of the process of developing and preparing the final documents of the national consensus for teaching undergraduate Brazilian dental students the dental caries curriculum in the Portuguese language. The final document was developed in three steps: a) The ABENO and LAOHA cariology group invited experts from all five regions of Brazil to participate in the discussion. The theoretical support for crafting the first draft of the consensus was based on two publications: National Curriculum Guidelines of the Dentistry graduation in Brazil, Ministry of Education (2021) and the competences described in the European Core Curriculum for Cariology (ORCA-ADEE, 2011); b) The group of experts was divided into 5 working groups: G1-Domain, Main and Specific Competences, G2-Essential knowledge, G3-Life course perspective, G4-Social determinants and dental caries, G5- Glossary. The document was finalized by thoroughly reviewing the process using Delphi methodology; c) The 5-chapter document (one from each working group) was submitted to three open public consultations in 2022 (May-June, August, and October) using Google-forms. The suggestions (content/wording) were discussed within the group as: totally accepted, partially accepted, and rejected. A total of 192 suggestions were registered from 31 dental schools in all regions of Brazil. The number of suggestions received per Group were: 84, 28, 26, 24, 30 suggestions for G1, G2, G3, G4 and G5, respectively. The majority of suggestions were totally accepted by the group of experts (n = 172, 89.6%), 15 were partially accepted (7.8%), and 5 were rejected. Conclusion The final document could be considered to be the first national consensus for teaching the dental caries curriculum in Brazil. language steps discussion publications 2021 (2021 ORCAADEE, ORCAADEE ORCA ADEE, ADEE (ORCA-ADEE 2011 2011) b groups G1Domain, G1Domain GDomain G1 Domain, Domain G G1-Domain Competences G2Essential GEssential G2 Essential knowledge G3Life GLife G3 Life perspective G4Social GSocial Social G5 Glossary methodology c 5chapter chapter one 202 MayJune, MayJune May June, June (May-June August October Googleforms.
