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 Purpose To associate maternal anxiety with sociodemographic factors, breastfeeding practices, oral habits, and the child’s entry into daycare among deaf and hearing (non-deaf) mothers. Methods This retrospective comparative cross-sectional study included 116 mothers (29 deaf and 87 hearing) of children aged between two and five years. Deaf mothers belonged to a reference center in the city, while hearing mothers were contacted in public daycares where their children were enrolled. Mothers underwent interviews covering socio-economic factors and child development-related aspects. Additionally, they completed the Brazilian Beck Anxiety Inventory, adapted for both deaf and hearing individuals, serving as instruments to assess anxiety. The Kolmogorov-Smirnov normality test, Kruskal Wallis test, Mann-Whitney test, and Poisson Regression were employed for statistical analyses (p<0.05). Results Deaf mothers exhibited anxiety scores one and a half times higher than hearing mothers. Moreover, mothers of children with thumb-sucking habits showed higher anxiety scores, while mothers whose children started attending daycare as infants demonstrated lower anxiety scores compared to mothers of children without such habits and who did not attend daycare. Conclusion Deaf mothers displayed higher anxiety levels when compared to hearing mothers. Children’s behaviors, such as thumb-sucking habits, and early enrollment in daycare during the first year of life influenced maternal anxiety. practices childs s nondeaf non (non-deaf crosssectional cross sectional 11 29 (2 8 years city enrolled socioeconomic socio economic developmentrelated development related aspects Additionally Inventory individuals KolmogorovSmirnov Kolmogorov Smirnov test MannWhitney Mann Whitney p<0.05. p005 p p<0.05 . 0 05 (p<0.05) Moreover thumbsucking thumb sucking Childrens Children behaviors 1 2 ( p00 p<0.0 (p<0.05 p0 p<0.

RESUMO Objetivo Associar a ansiedade materna aos fatores sociodemográficos, pratica de aleitamento, hábitos bucais e ingresso da criança em creche entre mulheres surdas e ouvintes. Método Participaram deste estudo transversal retrospectivo comparativo, 116 mães (29 surdas e 87 ouvintes) de crianças na faixa etária entre dois e cinco anos. As mães surdas pertenciam a um centro de referência da cidade e as mães ouvintes foram contatadas em creches públicas, onde seus filhos estavam matriculados. As mães foram submetidas a entrevista sobre fatores socioeconômicos e relacionados ao desenvolvimento dos filhos, além de realizarem o preenchimento do Inventário Brasileiro de Ansiedade de Beck, nas versões para surdos e ouvintes, que foram instrumentos usados para avaliar a ansiedade. O teste de normalidade de Kolmogorov-Smirnov, os testes de Kruskal Wallis, Mann-Whitney e Regressão de Poisson foram utilizados para análises estatísticas (p &lt;0,05). Resultados Mães surdas apresentaram escore de ansiedade uma vez e meia maior que mães ouvintes. Além disso, mães de crianças com hábito de sucção de dedo apresentaram maior escore de ansiedade e mães cujos filhos começaram a frequentar a creche ainda bebês apresentaram menor escore de ansiedade, quando comparados a crianças sem o hábito e que não frequentavam a creche. Conclusão Mães surdas apresentaram maior ansiedade quando comparadas às ouvintes.

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 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 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 .

RESUMO A trissomia 21 (síndrome de Down) é uma condição genética decorrente da presença de três cromossomos 21. Indivíduos diagnosticados com essa síndrome apresentam maior probabilidade de desenvolver problemas sistêmicos, além de distúrbios cognitivos, de desenvolvimento e psiquiátricos. Este artigo relata o caso de uma criança com síndrome de Down em tratamento para leucemia mieloide aguda, enfatizando seu impacto na qualidade de vida. A percepção da mãe sobre a qualidade de vida relacionada à saúde (QVRS) foi mensurada pelo Pediatric Quality of Life Inventory (PedsQL), Escalas Genéricas Core e Módulo Câncer. A percepção da mãe mostrou que o funcionamento físico e funcional indicava maior impacto negativo na vida da criança. Os menores escores foram nos domínios náusea e ansiedade em relação ao procedimento. O exame intraoral revelou dentição decídua incompleta com erupção ectópica. A criança teve abordagem multidisciplinar de saúde (pediatra, hematologista, gastroenterologista, cardiologista, fisioterapeuta e dentista). Portanto, é fundamental que os profissionais de saúde, inclusive os cirurgiões-dentistas, incorporem em sua prática o conhecimento sobre as dificuldades e aspectos emocionais dessa população, proporcionando um cuidado humanizado centrado no paciente. 2 sistêmicos cognitivos psiquiátricos aguda QVRS (QVRS PedsQL, PedsQL , (PedsQL) Câncer procedimento ectópica pediatra, pediatra (pediatra hematologista gastroenterologista cardiologista dentista. dentista . dentista) Portanto cirurgiõesdentistas, cirurgiõesdentistas cirurgiões dentistas, dentistas cirurgiões-dentistas população paciente (PedsQL

ABSTRACT Trisomy 21 (Down syndrome) is a genetic condition arising from the presence of three chromosomes at position 21. Individuals diagnosed with this syndrome have a greater likelihood of developing systemic problems, as well as cognitive, developmental, and psychiatric disorders. This paper reports a case of a child with Down syndrome under treatment for acute myeloid leukemia, emphasizing its impact on quality of life. The mother’ perception on health-related quality of life (HRQoL) was measuredby the Pediatric Quality of Life Inventory (PedsQL), Generic Core and Cancer Module Scales. The mother’s perception shown that physical and functional functioning indicated a higher negative impact on the child’s life. The lowest scores were in the domains nausea and anxiety about the procedure. Intraoral examination revealed an incomplete primary dentition with ectopic eruption. The child has had a multidisciplinary health care approach (pediatrician, hematologist, gastroenterologist, cardiologist, physiotherapist and dentist). Therefore, it is essential that health professionals, including dentists, to incorporateinto their practice the knowledge on the difficulties and emotional aspects of this population, providinga patient-centered humanized care. 2 problems cognitive developmental disorders leukemia mother healthrelated related HRQoL (HRQoL PedsQL, PedsQL , (PedsQL) Scales mothers s childs procedure eruption pediatrician, pediatrician (pediatrician hematologist gastroenterologist cardiologist dentist. dentist . dentist) Therefore professionals dentists population patientcentered patient centered (PedsQL

Resumo Investigar determinantes individuais e contextuais associados ao bullying em escolares de 8 a 10 anos. Foi realizado estudo transversal com 739 crianças. As crianças responderam uma pergunta sobre episódios de bullying relacionado a saúde bucal, um questionário sobre ansiedade infantil e disfunção orofacial. Os responsáveis forneceram informações sobre características sociodemográficas, distúrbios do sono e alfabetismo em saúde bucal. Examinadores treinados avaliaram as crianças para diagnóstico da cárie dentária pelo International Caries Detection and Assessment System, má oclusão por meio do Dental Aesthetic Index, disfunção orofacial pelo Nordic Orofacial Test-Screening e traumatismo dentário (Critério de Andreasen) (Kappa>0,80). As variáveis contextuais foram tipo de escola e renda mensal do bairro escolar. Estatística descritiva foi utilizada para caracterização da amostra. Modelos de regressão de Poisson multinível não ajustados e ajustados (p<0,05) foram usados. A prevalência do bullying foi 13,3%. Após análise ajustada a má oclusão (RP=1.59; IC95%:1.03-2.44) e a ansiedade (RP=1.79; IC95%:1.10-2.93) permaneceram associados ao bullying. Em relação ao contexto, a menor renda mensal do bairro da escola foi associada ao bullying (RP=1.75; IC95%:1.12-2.72). Má oclusão e ansiedade influenciaram a presença do bullying. A menor renda mensal do bairro escolar foi um determinante contextual importante para o aumento da prevalência de bullying. 1 anos 73 bucal sociodemográficas System Index TestScreening Test Screening Critério Andreasen Kappa>0,80.

Abstract Investigate individual and contextual determinants associated with bullying in schoolchildren eight to ten years of age. A cross-sectional study was conducted with 739 schoolchildren, who answered a question about episodes of bullying related to oral health and questionnaires addressing childhood anxiety and orofacial dysfunction. The guardians provided information on sociodemographic characteristics, sleep disorders, and oral health literacy. Trained examiners assessed the children for the diagnosis of dental caries using the International Caries Detection and Assessment System, malocclusion using the Dental Aesthetic Index, orofacial dysfunction using the Nordic Orofacial Test-Screening and traumatic dental injury (Andreasen criteria) (Kappa> 0.80). The contextual variables were the type of school and the monthly income of the school neighborhood. Descriptive statistics was performed to characterize the sample and unadjusted and adjusted (p <0.05) multilevel Poisson regression models were run. The prevalence of bullying was 13.3%. After the adjusted analysis, malocclusion (PR=1.59; 95%CI:1.03-2.44) and anxiety (PR=1.79; 95%CI:1.10-2.93) remained associated with bullying. In terms of context, the monthly income of the neighborhood of the school was associated with bullying (PR=1.75; 95%CI:1.12-2.72). Malocclusion and anxiety influenced the occurrence of bullying.

ABSTRACT The aim of this study was to undertake a cross-cultural adaptation of the eHealth Literacy Scale (eHEALS) instrument to measure digital health literacy of Brazilian adolescents. eHEALS is a scale consisting of 8 items that measure self-perception related to the consumption of electronic health information. This is a methodological study of cross-cultural adaptation, conducted out from February 2022 to June 2022. The following steps were carried out: a) assessment and adequacy of cultural equivalence by a committee of experts; b) back-translation; c) synthesis of back-translations; d) cognitive testing with 42 Brazilian adolescents, using cognitive interviews with probing questions. All items that were difficult to understand were adapted to the (language) context of Brazilian adolescents. Cronbach’s alpha coefficient for eHEALS-BrA was 0.81 and, if one of the items were excluded from the instrument, it ranged from 0.75-0.81. This version of the eHEALS proved to be culturally well-adapted to the context of Brazilian adolescents, and has the potential to measure digital health literacy in this population after having its validation confirmed through psychometric analyses. crosscultural cross (eHEALS adolescents selfperception self perception information 202 experts b backtranslation back translation back-translation c backtranslations translations back-translations d 4 questions language (language Cronbachs Cronbach s eHEALSBrA BrA 081 0 81 0.8 0.750.81. 075081 0.75 0.81. 75 0.75-0.81 welladapted well analyses 20 08 0. 750 0.750.81 07508 075 0.7 7 0.75-0.8 2 0.750.8 0750 07 0.75-0. 0.750. 0.75-0 0.750 0.75-

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.

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.

Resumo Os objetivos deste estudo foram realizar uma análise exploratória da prevalência de provável bruxismo em vigília (BV)e do sono (BS) utilizando diferentes critérios de diagnóstico baseados no Consenso Internacional; avaliar a associação entre o autorrelato e os sinais/sintomas clínicos em adolescentes. Participaram deste estudo transversal 403 adolescentes de 12 a 19 anos de idade matriculados em escolas públicas e privadas de Belo Horizonte, Brasil. Os pais/responsáveis responderam um questionário sobre dados sociodemográficos e estado de saúde dos adolescentes. Os adolescentes relataram atividades do BV (ranger e apertar) e BS (ranger, bracing e thrusting) e dores de cabeça frequentes. Um exame clínico foi realizado nos adolescentes para avaliar os sinais/sintomas clínicos do bruxismo (dor à palpação nos músculos masseter e temporal, marcas de endentação na língua e linha alba, desgaste dentário por atrição). Análises descritiva e teste Qui-quadrado de Pearson foram realizados (P≤0,05). A média de idade dos adolescentes foi de 14,3±1,5 anos e 58,1% eram do sexo feminino. O autorrelato de BS foi identificado em 31% dos participantes e o autorrelato do BV em 51,6%. Quase a totalidade dos adolescentes (99%) apresentaram pelo menos um dente com desgaste dentário (98,5% em esmalte; 0,5% em dentina), com média de 12,4±5,7 dentes acometidos. Dependendo do critério de diagnóstico, a prevalência do provável BS e BV variou de 0- 99% e 0,2- 99%, respectivamente. Uma grande inconsistência foi identificada na prevalência de provável BV e BS em adolescentes, que foram influenciadas pelos diferentes sinais/sintomas usados como critério de diagnóstico.

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.
