ABSTRACT Objective: To assess the impact of Molar Incisor Hypomineralization (MIH) and confounding factors on oral health-related quality of life (OHRQoL) according to the perception of 8 to 10-year-old children and their parents/caregivers. Material and Methods: A cross-sectional study including 403 students aged 8-10 years was carried out, in which OHRQoL was measured using the Child Perceptions Questionnaire administered to both children and parents/caregivers. The diagnosis of MIH was performed according to the previously proposed index. Dental caries experience, malocclusion, and sociodemographic factors were evaluated as confounders. Cluster analysis and Poisson regression with robust variance (p<0.05) were performed. Results: The prevalence of MIH was 13.4%. Parents/caregivers of children with MIH in incisors showed a higher impact prevalence in the emotional well-being domain (PR=1.92; 95%CI=1.16-3.19). Children with hypoplasia had a higher prevalence of negative impact on OHRQoL in the oral symptoms domain (PR=1.51; 95%CI=1.03-2.23). According to the perception of parents/caregivers, dental caries experience had a negative impact on the quality of life of students in the emotional well-being domain (PR=4.19; 95%CI=1.06-16.49) and in the total questionnaire score (PR=3.21; 95%CI=1.06-9.71). Conclusion: According to the perception of parents/caregivers, children with MIH in incisors showed a greater impact on OHRQoL. Additionally, the presence of hypoplasia affected the self-perception of OHRQoL in children, and caries experience influenced the OHRQoL of children, as perceived by parents/caregivers.

ABSTRACT Objective: To assess the influence of perceived stress during the COVID-19 pandemic over awake bruxism (AB) and sleep bruxism (SB). Material and Methods: Observational web-based research carried out in a state in the Brazilian Northeast. The sample was composed of dental students from seven faculties, divided into three groups: beginning (1-4 semesters), middle (5-7), and end (8-10). An online questionnaire was constructed: Socio-demographic, Perceived Stress Scale (PSS-10), Self-reported AB and SB, and COVID-19 Fear Scale. Data were collected from April to June 2021 by sending the questionnaire through WhatsApp®, e-mail, and Instagram®. After bivariate analyses, a multiple logistic regression model was performed to discriminate variables for perceived stress and AB and SB. Hosmer and Lemeshow and chi-square tests were used to check the model's goodness of fit. Results: A total of 391 dental students participated in this research - most women (69.8%), unmarried (69.8%), family income less than three minimum wages (60.9%), self-reported physical activity (63.3%). Perceived stress was low to moderate (72.1%), SB was 39.6%, AB was 49.6%, and low COVID-19 fear was 81.1%. COVID-19 fear (3.03), being female (2.47), and using psychotropic (2.53) increases the chance of being stressed. Perceived stress can predict AB in models 1 (p=0.008) and 4 (p=0.039). There was no significance for perceived stress and SB. Conclusion: Perceived stress during the COVID-19 pandemic influenced awake bruxism. Objective COVID19 COVID 19 COVID-1 (AB .

Abstract In dentistry, most equipment is designed for right-handed (RH) individuals. Thus, left-handed (LH) individuals are often forced to adapt to demanding RH working conditions, and therefore, experience difficulties in their practice. The objective of this study was to determine the prevalence of left handedness among dental students at the Dental Clinic of Monastir, Tunisia, and to investigate the difficulties for LH individuals during clinical practice. A cross-sectional study was conducted among dental students during the academic year from September 2019 to March 2020. An adaptation of the Grad-Corllet Diagram and a specific questionnaire on clinical practices were administered to 221 participants. Data were analyzed using SPSS 24.0 statistical software for descriptive statistics and the chi-square test was performed (with a 5% significance level). The study revealed that 18.1% of dental students were LH. Among which, 82.5% of LH students had difficulties using instruments designed for RH dentists, 47.5% of LH students preferred the 3 o’clock working position, and 77.5% of LH students preferred to work in a sitting position. Most LH students (70%) reported that endodontic treatment was the most difficult procedure to perform. All students, whether RH or LH, presented a higher percentage of pain in the lumbar and neck/cervical regions; however, LH students presented higher values (77.5%) with statistically significant differences being reported for lower back pain (p = 0.026) and neck pain (p = 0.012). This study highlights the difficulties that LH dental students face in performing dental work. Dental Schools should provide LH students with appropriate equipment and a proper learning environment. dentistry righthanded right handed (RH Thus lefthanded (LH conditions therefore practice Monastir Tunisia crosssectional cross sectional 201 2020 GradCorllet Grad Corllet 22 participants 240 24 0 24. chisquare chi square 5 level. level . level) 181 18 1 18.1 which 825 82 82.5 dentists 475 47 47.5 oclock o clock position 775 77 77.5 70% 70 (70% perform neckcervical cervical regions however (77.5% p 0.026 0026 026 0.012. 0012 0.012 012 0.012) environment 20 202 2 18. 8 82. 4 47. 7 77.

Abstract Objective: To present the profile of hospitalizations due to transport accidents in individuals aged 0-19 years in a reference hospital for urgent and emergency traumatology care. Material and Methods: This retrospective study is grounded on analyzing medical records of children and adolescents hospitalized due to transport accidents in 2016 and 2017. The bivariate analyses included Chi-square and Fischer’s exact tests and binary logistic regression, with a 5% significance level. Results: Four hundred and seventy-five (43.7%) of the 1,088 medical records investigated corresponded to transport accidents, and accidents involving motorcycles were the most frequent (68.3%), affecting adolescents (81.3%), while children were more involved in accidents as pedestrians (57.1%). Advancing age increases the likelihood of the outcome, with a significant association in the multivariate analysis (p<0.001). The mandible was most frequently affected in maxillofacial fractures. Conclusion: Transport accidents predominantly affect male adolescents, involving motorcycles, and the lower limbs are the most affected. The mandible was the most affected bone in maxillofacial fractures.

ABSTRACT Objective: To estimate the prevalence of dental fear and evaluate its association with dental caries and with Molar Incisor Hypomineralization (MIH) in schoolchildren aged 11-14 years. Material and Methods: A cross-sectional study was conducted with 375 adolescents in Campina Grande, Brazil. Socioeconomic and oral health information was collected, while dental fear was measured using the Children’s Fear Survey Schedule-Dental Subscale (CFSS-DS). The diagnosis of dental caries and MIH was performed by three trained examiners (κ ≥ 0.61) using the International Caries Detection & Assessment System – ICDAS II and a previously validated index, respectively. Data were descriptively analyzed using the Chi-Square, Fisher's Exact, and Poisson regression tests with robust variance (p<0.05). Results: The prevalence of dental fear was 18.4%, and the mean CFSS-DS total score was 28.96 ± 8.92. After adjusting for covariates family structure, schooling of parents/guardians, type of dental health service and dental pain in the last six months, the prevalence of dental fear was associated with dental pain in the last six months (PR=2.03; 95%CI=1.31-3.16; p=0.002). Conclusion: Although no association was found between dental fear, dental caries and MIH in adolescents, those who experienced dental pain in the last six months had a higher prevalence of dental fear.

Abstract Objective: To describe systemic manifestations, the characteristics related to tooth eruption, and the occurrence of enamel defects in children with Congenital Zika Virus Syndrome (CZS). Material and Methods: Prospective case series based on nine children with confirmed CZS diagnosis assisted at a reference center in a municipality in the Northeast Region of Brazil. Through a structured interview directed to mothers, information related to prenatal, delivery, and postpartum periods was collected. Tooth eruption was monitored through clinical examinations for 36 months. The modified developmental defect of enamel index (DDE) was used to identify opacities and hypoplasia. Data were presented using descriptive statistics. Results: A high proportion (77.8%) had microcephaly, and 55.5% had low birth weight. Musculoskeletal disorders, swallowing difficulty, and self-injury practices were present in all children. Among the systemic findings, visual impairment (77.8%) and seizures (77.8%) were widely reported. Concerning disorders related to the stomatognathic system, bruxism (66.7%) and difficulty in sucking (33.3%) were present. For most children (77.8%), the deciduous right lower central incisor was the first tooth to erupt (minimum 8 months and maximum 17 months). Enamel defects were diagnosed in only two children (22.2%). Conclusion: A wide range of systemic manifestations was observed in children with CZS, including visual impairment and musculoskeletal disorders. Delayed eruption of the first deciduous tooth was also observed. Enamel defects were present in a small proportion of children.

Abstract Limited research attention has been paid to Turkish dentists’ perceptions of child abuse and neglect (CA/N). This study aimed to examine Turkish dentists’ knowledge about, attitudes toward, and perceptions of CA/N. A total of 229 Turkish dentists responded to the self-administered, valid and reliable questionnaire. It consisted of 34 questions that could be classified into the following conceptual categories: a) sociodemographic data, b) knowledge about legal procedures and the orofacial characteristics and findings that are indicative of CA/N, and c) self-efficacy and attitudes toward CA/N. Multivariate analysis of variance was conducted and partial eta squared coefficients were used statistically. Knowledge about legal obligations was associated with occupational experience, highest CA/N education, frequency of child dental treatment. Prior experience with case of suspected CA/N demonstrated the greatest effects. Knowledge about the orofacial characteristics and findings that are indicative of CA/N was associated with prior experience with at least one case of suspected CA/N. The most frequently provided reasons for failure to report cases of suspected CA/N were fear that the child would be harmed. Turkish dentists demonstrated moderate levels of knowledge about their legal obligations and the orofacial characteristics and findings that are indicative of CA/N. Dentists should receive detailed education on CA/N in their undergraduate and postgraduate education. In addition, it is necessary to increase awareness and knowledge about CA/N by providing in-service trainings at the institutions where they work.

According to the CFSS-DS, 53.5% of children had high dental fear. Items “Injections,” “Having a stranger touch you,” “The dentist drilling,” “Having somebody put instruments in your mouth,” “Choking,” and “Having to go to the hospital” had the highest median values. A significant difference was observed between ages for the item “Having a stranger touch you” (p=0.001). Conclusion: The item “Having a stranger touch you” in the CFSS-DS questionnaire showed a statistically significant difference with age, while no differences were found regarding sex.

Introduction: The COVID-19 pandemic brought changes in all segments of society, including with impact on dental education. Objective: To evaluate the fear of COVID-19 in dental students. Methodology: Cross-sectional study composed of 40 dental students from a private university. Data were collected regarding sociodemographic issues and the Fear of COVID-19 Scale (FCV-19S) was applied. The data were tabulated using the IBM SPSS software and analyzed descriptively (absolute and percentage frequencies, measures of central tendency and variability). Results: Most students were female (60.0%), between 16 and 20 years old (50.0%) and 45.0% had a monthly family income of more than one and less than three minimum wages. The average of the total score on the FCV-19S was 18.45 (SD = 6.08), with a minimum score of 7 and a maximum of 30. Most students showed “little fear” of COVID-19 (55.0 %). The items “I am very afraid of COVID-19”, “I am afraid of dying because of COVID-19”, and “I get nervous or anxious when I see news in the newspapers and on social media about COVID-19” obtained the highest average values. Conclusion: Most students showed little fear of COVID-19, despite the items “I am very afraid of COVID-19”, “I am afraid of dying because of COVID-19” and “I get nervous or anxious when I see news in newspapers and social media about COVID-19” having obtained the highest average values.

Abstract This study aimed to identify the prevalence of molar-incisor hypomineralization (MIH) in schoolchildren and its association with dental caries experience. This was a cross-sectional study with a sample of 471 children aged 8 to 10 years. Data were collected via a sociodemographic questionnaire. Intra-oral clinical examination was done to identify and diagnose MIH (EAPD Criteria) as well as dental caries (ICDAS Index). Statistical analyses were performed with Person’s Chi-square, Fisher’s exact, and Mann-Whitney tests, and Poisson regression models were built. Statistical significance was set at an alpha-level of 0.05. The prevalence of MIH in our participants was 9.8%, with lesions being mostly of the mild form (65.2%) and affecting the first permanent molars but not the incisors in 54.2% of the children. Dental caries was observed in 88.1% of subjects. We observed a significant association between dental caries and the following variables: presence of MIH (p < 0.01; PR = 1.13), dental visit (p < 0.02; PR=0.92), and parents or legal guardians’ education level (p < 0.05; PR = 1.07). A MIH diagnosis was also significantly associated with family income (p < 0.05; PR = 4.09). Children with MIH had more caries lesions on molar surfaces (p < 0.01; PR = 4.05). The prevalence of MIH was found to be moderate, based on previous studies, and the presence of enamel defect was associated with dental caries. The teeth most affected by MIH lesions were the first permanent molars.

ABSTRACT Objective: To evaluate the quality of life of mothers of Brazilian children with congenital Zika virus syndrome (CZS) and associated factors. Material and Methods: This cross-sectional study assessed the quality of life (QoL) of 65 mothers of children diagnosed with CZS using the WHOQOL-bref questionnaire. Information related to mothers and children's characteristics and aspects of QoL (physical, psychological, social and environment domains) was collected. Data were presented using descriptive and inferential statistics. Associations between independent variables and quality of life outcome were carried out through bivariate analyses, adopting a 5% significance level. Results: The “physical” domain showed the highest score (65.98 ± 17.62), while the “environment” domain showed the lowest score (48.55 ± 14.75). The quality of life for the physical domain was associated with maternal schooling and child's sex, while the psychological domain was associated with family income and child's sucking difficulty. Conclusion: Socioeconomic characteristics and comorbidities were associated with mothers' QoL. Knowledge of QoL determinants and their impact on different dimensions of life can serve as a guide for interventions aimed at improving the QoL of this population.

RESUMO A síndrome respiratória aguda grave do novo coronavírus, SARS CoV-2, que se tornou uma pandemia, foi relatada pela primeira vez em Wuhan, Hubei, China em dezembro 2019. Pode acarretar sintomas leves, porém em alguns casos pode provocar graves complicações levando o indivíduo ao óbito. A doença se espalha através de gotículas de aerossol e tem um período de incubação do coronavírus estimado entre 2 e 14 dias (período este no qual o paciente tem alto potencial de infectar outras pessoas). Os endodontistas apresentam alto risco de exposição ao COVID-19 quando comparado a outros profissionais de saúde, pois a maior parte do trabalho envolve a geração de aerossóis e os atendimentos a pacientes em situações emergentes, como pulpite irreversível sintomática, periodontite apical sintomática, abscesso apical agudo e lesões dentárias traumáticas são imperativos. Dessa forma, essa revisão crítica aborda considerações sobre o atendimento endodôntico, nesta época de pandemia, cujas emergências imprimem necessidade real de tratamento, bem como os cuidados que devem ser adotados visando minimizar riscos tanto para o profissional quanto para os pacientes que buscam a resolução dos seus quadros clínicos de dor.

ABSTRACT The severe acute respiratory syndrome of the new coronavirus, SARS CoV-2, which became a pandemic, was first reported in Wuhan, Hubei, China, in December 2019. It can cause mild symptoms, but in some cases, it can cause serious complications, leading to death. The disease spreads through aerosol droplets and has an estimated incubation period between 2 and 14 days (a period in which the patient has high potential to infect other people). Endodontists have a high risk of exposure to COVID-19 when compared to other health professionals, since most of the work involves the generation of aerosols and care for patients in emergency situations, such as symptomatic irreversible pulpitis, symptomatic apical periodontitis, acute apical abscess and traumatic dental injuries, is imperative. Thus, this critical review addresses considerations about endodontic care in times of pandemic, whose emergencies imply a real need for treatment, as well as the care that must be adopted to minimize risks for both professionals and patients who seek the resolution of their clinical pain conditions.

Resumo O objetivo deste estudo foi investigar a prevalência de medo odontológico e avaliar sua associação com a cárie dentária e a Hipomineralização molar-incisivo (HMI), em escolares de 8 a 10 anos, em um município da região Nordeste do Brasil. Foram coletados dados de 466 estudantes matriculados em escolas públicas urbanas, em um estudo transversal. Os pais/responsáveis responderam a um questionário abordando características sociodemográficas, o medo odontológico foi mensurado por meio do Children’s Fear Survey Schedule-Dental Subscale (CFSS-DS), e os exames clínicos foram realizados por três examinadores calibrados para o diagnóstico de cárie dentária, utilizando o índice International Caries Detection & Assessment System (ICDAS II) e, por um índice previamente validado, para HMI. Foi realizada a análise descritiva dos dados e as associações entre medo odontológico, cárie dentária e HMI foram avaliadas pela regressão robusta de Poisson para amostras complexas (p<0,05). A prevalência de medo odontológico foi de 21,6%, e o escore médio total do CFSS-DS foi de 29,97 (IC 95%=29,05-30,89). No modelo multivariado ajustado, a prevalência de medo odontológico esteve associada à renda familiar (RP=1,78; IC 95%=1,02-3,08; p= 0,041). A renda familiar mensal foi associada ao medo odontológico em crianças, enquanto a cárie dentária e a HMI não foram associadas ao medo odontológico.

Abstract The aim of this study was to investigate the prevalence of dental fear and to evaluate its association with dental caries and molar incisor hypomineralization (MIH) in schoolchildren aged 8-10 years from a municipality in Northeastern Brazil. Data from 466 students enrolled in urban public schools in a cross-sectional study were collected. Parents/guardians answered a questionnaire addressing sociodemographic characteristics, dental fear was measured by means of the Children’s Fear Survey Schedule-Dental Subscale (CFSS-DS) and clinical examinations were performed by three calibrated examiners for diagnosis of dental caries, using the International Caries Detection & Assessment System - ICDAS II and a previously validated index for MIH. Descriptive data analysis was performed, and associations between dental fear, dental caries and MIH were analyzed using robust Poisson regression for complex samples (p<0,05). The prevalence of dental fear was 21.6%, and the mean total CFSS-DS score was 29.97 (CI 95%=29.05-30.89). In the multivariate adjusted model, the prevalence of dental fear was associated to family income (PR=1.78; CI 95%=1.02-3.08; p= 0.041). Monthly family income was associated with dental fear in children, whereas dental caries and MIH were not associated with dental fear.

A new Coronavirus (2019-nCov, renamed SARS-CoV-2) was identified in the Chinese city of Wuhan in late 2019, and was declared a pandemic by the World Health Organization, on March 11, 2020. As it is a highly infectious disease, major regional and national changes have been made,nbsp;social isolation was recommended, which led to the interruption of various services, including elective dental treatments. This review aimed to identify the changes that occurred in the post-COVID-19 orthodontic practice scenario. For such, a search was made for articles published in the bibliographic bases PubMed, Scopus and SciELO, using the keywords “Orthodontics” and “Covid-19”. From the eligibility criteria, 11 articles were selected for analysis. It was found that social isolation impacted the scheduling of orthodontic appointments and patient’s anxiety about the duration of treatments. The use of teleodontology proved to be an ally in screening and in patient care. Preventive infection control must be adopted for safe orthodontic practice.

The effects of the Coronavirus Disease 2019 (COVID-19) pandemic on the mental health of healthcare professionals has become a concern, particularly among those who are in close contact with infected patients, including dentists. The aim of this critical literature review was to analyze the possible implications of the COVID-19 pandemic on the mental health of dentists. This bibliographic search was carried out in the PubMed, Web of Science and Scopus databases, using the following search keywords “Psychiatry OR anxiety OR fear OR depression OR psychological distress OR mental health” AND “COVID-19 OR SARS-CoV-2” AND “Dentists OR dental practice. Original research publications that included data on the mental health status of dentists during the COVID-19 pandemic were included. Data were tabulated in Microsoft Excel 2016 for Windows and descriptively presented. Eleven publications were eligible for this review. All studies had cross-sectional design. Most of them used questionnaires created by study researchers (81.8%) and were carried out in Italy (45.5%). The number of participants ranged from 14 to 1,500. Effects on the mental health of dentists during the COVID-19 pandemic were observed, regarding fear of contamination, anxiety, concerns, stress, depression, job insecurity, subjective overload, perceived risk and feelings and emotions. It was concluded that the COVID-19 pandemic had negative impact on the mental health of dentists, with high prevalence of fear, anxiety and concern, among other psychological symptoms.
