ABSTRACT Objective: To evaluate questions concerning oral medicineand pharmacology-related specialties of asynchronous dental teleconsulting sessions of the Telehealth Brazil Networks Program. Material and Methods: Data were collected from secondary databases of asynchronous dental teleconsulting sessions of the telehealth centers of Minas Gerais from July 2015 to July 2017. The variables for dental underlying fields and the types of questions were evaluated. Descriptive analysis was performed with the SPSS v.22.0 program. Results: 3,920 teleconsulting sessions were referred to the telehealth centers of Minas Gerais during the study period. Regarding oral medicine-related questions (n=745), most (n=469; 62.95%) addressed diagnosis, whereas the underlying field questions mostly regarded fungal, viral, and bacterial infections (17.3%), biopsies (16.4%), developmental defects and dental abnormalities (9.9%), and soft tissue tumors (9.4%). Pharmacology-related questions (n=738) mostly addressed general approaches (n=672; 91.06%), and the most common questions were about underlying fields' prescriptions (44.7%), anesthetics (17.6%), adverse effects of medications and anesthetics (10.2%), and selection of anesthetics for patients with systemic conditions (9.8%). Conclusion: Most teleconsulting sessions regarded conditions or procedures common in primary health care and essential for diagnosis and treatment planning at all care levels, which suggests a need for more academic learning processes for healthcare professionals, especially in dentistry primary fields.

Abstract Background Patients with kidney disease on Hemodialysis (HD) are susceptible to Coronavirus Disease (COVID-19) due to multiple risk factors. Aim This study aims to report the prevalence of antibodies against SARS-CoV-2 among patients on hemodialysis before vaccination in Brazil and to compare with clinical, demographic, and laboratory data. Methods Blood samples from 398 Chronic Kidney Disease (CKD) patients treated in three different private institutions in Rio de Janeiro State, Brazil were submitted to the total anti-SARS-CoV-2 testing. Kidney, liver, and hematological markers were also determined. Respiratory samples were tested by real-time PCR for SARS-CoV-2 RNA and positive samples were subjected to high-throughput sequencing on the MinION device. Results Overall, anti-SARS-CoV-2 prevalence was 54.5 % (217/398) and two individuals had SARS-CoV-2 RNA with variant B.1.1. High anti-SARS-CoV-2 seroprevalence was found in male gender and those with hospital admission in the last 3-months before the inclusion in the study. Lower red blood cell count was observed in the anti-SARS-CoV-2 seropositive group. High levels of anti-SARS-CoV-2 were found in those who reported symptoms, had low levels of eosinophils and low hematocrit, and who practiced physical activity. Conclusion High prevalence of anti-SARS-CoV-2 was found in CKD patients before the universal immunization in Brazil suggesting that dialysis patients were highly exposed to SARS-CoV-2.

Abstract This study aimed to translate and to perform the cultural adaptation of the instrument Illness Perception Questionnaire-Revised for Dental (IPQ-RD) into Brazilian Portuguese. The IPQ-RD consists of 34 items that assess the cognitive and emotional representation/perception of parents/caregivers of children with dental caries, with response options on a 5-point Likert scale, ranging from “Strongly agree” (score 1) to “Strongly disagree” (score 5). The higher the score, the lower the perception of the disease. The protocol consists of translation into Brazilian Portuguese, back-translation into English, revision by an Expert Review Committee, and pre-test (application in parents/caregivers of children in dental care). For some questions, the translated versions were identical (T1 = T2); for others, one version was preferred (T1 or T2); for still others, it was decided to modify terms to obtain greater clarity on the item (T3). In the first pre-test, three questions were misunderstood by more than 15% of the sample, after which the items were reviewed by the Expert Review Committee. In the second pre-test, the adapted version was applied to a new sample of parents/caregivers (n = 15) and the questions were understood by more than 85% of the participants. The Brazilian Portuguese version of the IPQ-RD was well understood by the evaluated population.

Abstract Behavioral characteristics may also take part in the etiology of dental caries. Sedentary behavior, especially watching television, is associated with increased intake of foods high in fat or free sugar, which could influence the occurrence of dental caries. The aim of this study was to assess the mediating effect of eating pattern on the relationship between television exposure time and the presence of dental caries in children. A cross-sectional study was conducted with a representative sample of 580 parent-child dyads with children aged 7 to 8 years in 20 public schools in Pelotas, Brazil. Parents or legal guardians were interviewed and provided information on demographic/socioeconomic data, children’s daily television exposure time, and answered the Biological Rhythms Interview for Assessment in Neuropsychiatry for Kids (BRIAN-K-eating pattern domain). Caries was evaluated through clinical examination. The mediating effect of eating pattern on the relationship between television exposure and presence of dental caries was estimated using the parametric g-formula. Prevalence of dental caries was 63%, and 22% of children watched TV 4 or more hours per day. Television exposure had no direct effect on the dental caries experience [odds ratio (OR): 1.05 (95% confidence interval (95%CI): 0.92–1.19)]. Nevertheless, difficulty maintaining regular eating pattern mediated the natural indirect effect of television exposure time (≥ 4 hours/day) on dental caries experience [OR: 1.07 (95%CI): 1.01–1.14)]. The results of this study confirm the indirect pathway between television viewing and dental caries and the role of disordered eating patterns in this association. behavior sugar crosssectional cross sectional 58 parentchild parent child 2 Pelotas Brazil demographicsocioeconomic demographic socioeconomic data childrens s BRIANKeating BRIAN K domain. domain . domain) examination gformula. gformula g formula. formula g-formula 63 63% 22 day odds OR (OR) 105 1 05 1.0 95% 95 (95 95%CI 95CI CI (95%CI) 0.92–1.19. 092119 0.92–1.19 0 92 19 0.92–1.19)] Nevertheless ≥ ( hours/day hoursday [OR 107 07 1.01–1.14. 101114 1.01–1.14 01 14 1.01–1.14)] association 5 6 (OR 10 1. 9 (9 (95%CI 09211 0.92–1.1 0.92–1.19) 10111 1.01–1.1 1.01–1.14) 0921 0.92–1. 1011 1.01–1. 092 0.92–1 101 1.01–1 09 0.92– 1.01– 0.92 1.01 0.9 0.

Abstract The perceptions of parents/caregivers regarding their children’s oral health can influence the standard of care and decision-making regarding oral health. The children’s perspective on their own oral health-related quality of life (OHRQoL) may differ from the parents/caregivers’ views. This cross-sectional study aimed to analyze the agreement between the perceptions of parents/caregivers and schoolchildren regarding OHRQoL. It was conducted with a sample of children between 8 and 11 years old and their parents/caregivers from Pelotas. Children answered the Child Perceptions Questionnaire 8-10 (CPQ), and parents/caregivers answered the short form of the Parental-Caregiver Perceptions Questionnaire (P-CPQ). Socioeconomic data were also collected. Children’s dental caries, traumatic dental injuries, and malocclusions were examined. The Spearman’s correlation test was performed. A total of 119 parents/caregivers-children pairs were included. There was an agreement between the total scores of parents/caregivers and children (0.2770; p = 0.003), in the oral symptoms (0.1907; p = 0.038), and functional limitations (0.2233; p=0.015) domains. The Bland-Altman graph showed an agreement between children’s and parents/caregivers’ OHRQoL total score, but there was an underestimation of approximately two points in the parents/caregivers’ perception compared to the children’s score. There was an agreement between the reports of parents/caregivers and children regarding children’s OHRQoL. parentscaregivers parents caregivers childrens s decisionmaking decision making healthrelated related (OHRQoL views crosssectional cross sectional 1 Pelotas 810 10 8-1 CPQ, CPQ , (CPQ) ParentalCaregiver Parental Caregiver PCPQ.

Abstract The salutogenic theory studies how and why people remain healthy even in adverse and stressful situations, having as central idea the sense of coherence (SOC). The higher the SOC, that is, the overall ability to see life, the more effectively the individual will be able to cope with the difficulties of life. This study aimed to verify the relationship between maternal SOC and behaviors related to oral health of pre-school children of the city of Pelotas/RS. A cross-sectional study was carried out on a sample of children aged 2 to 5 years old and their mothers, attending in 12 health care centers randomly selected. A total of 534 dyads participated. Demographic information, socioeconomic status, oral hygiene and feeding habits of the child, use of dental services by the child, screening of common mental disorders of the mother and evaluation of the maternal sense of coherence were collected. The associations between outcome variables (frequency of eating sweet foods and drinks between meals, how the child's teeth are brushed and experience of dental consultation of the child) and maternal demographic, socioeconomic and psychosocial characteristics were assessed by multivariate analysis using Poisson regression analysis with robust variance (p<0.05). The prevalence of inadequately brushing the teeth (the child brushes the teeth alone or never brushed) was 70% higher among children whose mothers had less SOC than in children of mothers with more SOC. The findings indicate that maternal SOC may be a psychosocial indicator in the acquisition of appropriate oral hygiene habits in preschoolers.

Resumo A teoria salutogênica estuda como e porque as pessoas permanecem saudáveis mesmo em situações adversas e estressantes, tendo como ideia central o senso de coerência (SOC). Quanto maior o SOC mais efetivamente o indivíduo será capaz de enfrentar as dificuldades da vida. Este estudo objetivou verificar a relação entre SOC materno e os comportamentos relacionados com a saúde bucal de pré-escolares da cidade de Pelotas/RS. Um estudo transversal foi realizado em uma amostra de crianças de 2 a 5 anos e suas mães em 12 Unidades Básicas de Saúde (UBS) sorteadas aleatoriamente. Participaram 534 díades. Informações demográficas, socioeconômicas, hábitos de higiene bucal e de alimentação do filho, utilização de serviços odontológicos pelo filho, rastreamento de transtornos mentais comuns da mãe e avaliação do SOC materno foram coletadas. As associações entre as variáveis de desfecho (frequência de ingestão de alimentos e bebidas doces entre as refeições, como os dentes da criança são escovados e experiência de consulta odontológica da criança) e as características demográficas, socioeconômicas e psicossociais materna foram avaliadas através de análise multivariada utilizando-se a regressão de Poisson com variância robusta (p<0,05). A prevalência de escovar os dentes de forma inadequada (a criança escova os dentes sozinha ou nunca ter escovado) foi 70% maior entre as crianças cujas mães apresentaram menor SOC quando comparadas às crianças de mães com maior SOC. Os achados indicam que o SOC materno pode ser um indicador psicossocial na aquisição de hábitos de higiene bucal adequados em pré-escolares.

Abstract The aim of this study was to evaluate the quality of curved root canal preparation, torsional fatigue, and cyclic fatigue of rotary systems manufactured with different NiTi alloys. Ninety single-rooted canals with curvatures of 15° to 30o were scanned and divided into three groups according to the rotary system used: BT-Race (BTR) – 10.06, 35.00, 35.04; SequenceRotaryFile (SRF) – 15.04, 25.06, 35.04; and ProDesignLogic (PDL) – 25.01, 25.06, 35.05. Each system was used on three specimens. The teeth were prepared, scanned, and analyzed to assess increase in volume, transportation, and centering ability of the root canal. Torsional fatigue of glide path instruments (BTR 10.06, SRF 15.04 and PDL 25.01) and cyclic fatigue of the finishing instrument (BTR 35.04, SRF 35.04 and PDL 35.05) were obtained by analyzing completely new instruments (n = 10) and instruments after they had been used three times (n = 10). After the torsional and cyclic fatigue tests, the fractured surface of the new and used instruments were examined by scanning electron microscopy. Increase in volume, canal transportation, and centering ability showed no significant differences among the groups (p > 0.05). The torsional test showed that SRF 15.04 produced the highest torque values for both new and used instruments, followed by PDL 25.01 and BTR 10.06 (p < 0.05). PDL 25.01, both new and used, exhibited higher values of angular deflection followed by SRF 15.04 and BTR 10.06 (p < 0.05). As regards cyclic fatigue, use of PDL 35.05, both new and used, required a longer time and larger number of cycles than did SRF 35.04 and BTR 35.04 (p < 0.05). Clinical use affected the torsional fatigue of BTR; however, cyclic fatigue was not significantly affected (p < 0.05). All rotary systems were able to prepare the curved canals satisfactorily and were used safely on the three specimens. Relative to torsional fatigue, SRF 15.04 exhibited a higher torque, and PDL 25.01, higher angular deflection. BTR 10.06 was the most affected by clinical use. PDL 35.05 showed greater resistance to cyclic fatigue.

Abstract This work aims to analyze and compare the sedimentological data of Ellsworth Mountains, West Antarctica: Patriot/Independence Hills and Union Glacier, and how sedimentological data can be used to infer sediment entrainment. Particular attention was concentrated on morainic deposits. Remote sensing data was used in the identification of deposits and the ice flow; granulometric, morphoscopic, and geochemical analyses were applied to investigate the sedimentary origin and transport history. Sediment rich in Si Al, Fe, and Ca predominate in Independence Hills and Rossman Cove but Ca prevails in Elephant Head. CIA indicated low values, which depict low chemical weathering processes. X-ray diffraction reveals the presence of minerals that constitute the local rocks in the Union Glacier area, and from the unexposed basement rocks in Independence Hills. Principal Component Analysis and Cluster Analysis results suggest the sediment is related to the local rocks in the Union Glacier and distinct exotic sources in Independence Hills, associated with far-traveled sediment. It is also observed the influence of distinct processes of entrainment sediment on its granulometric and morphoscopic characteristics.

Abstract Filling materials should be restricted to the root canal space. However, sometimes it is impossible to control the apical extrusion, in this case, the fate of the filling material and the result of the treatment will depend on its physicochemical properties and biocompatibility. Objective To evaluate the tissue response and bone repair capacity of endodontic sealers that were implanted in the calvaria of Wistar rats, forming the groups (n=16): AH Plus and Sealer Plus, compared to the clot group. Methodology On days 30 and 60, the animals were euthanized, the calvaria was removed and processed for hematoxylin-eosin, immunohistochemistry for collagen type I, Picrosirus red and microtomographic analysis. Data were subjected to ANOVA and Tuckey tests (p<0.05). Results At 30 days, all groups showed an intense inflammatory reaction (p>0.05). At 60 days, the AH Plus and Sealer Plus maintained an intense inflammatory infiltrate compared to the clot group (p<0.05). We observed immunopositive areas for type I collagen in all groups at 30 days and 60 days (p>0.05). We observed more red collagen fibers for the Sealer Plus compared to the clot group at 30 days (p<0.05). Considering the total fibers, the clot group at 30 days compared to 60 days after surgery showed an increase in the amount of matrix (p<0.05). There were no statistical differences between groups for green and yellow fibers (p>0.05). Regarding morphometric parameters, at 30 days, the newly formed bone volume and number of bone trabeculae were higher in the groups with sealers compared to the clot group (p<0.05). At 60 days, AH Plus and Sealer Plus showed greater bone neoformation compared to the clot group (p<0.05). Conclusions Despite AH Plus and Sealer Plus induced an intense inflammatory reaction, they can be considered biocompatible materials, since they allowed bone repair.

Abstract Objective: To translate and culturally adapt the Modified Child Dental Anxiety Scale - Faces (MCDASf) into Brazilian Portuguese. Material and Methods: The MCDASf consists of eight questions about anxiety toward dental procedures that are answered on a five-point Likert scale ranging from “not worried” (1 point) to “very worried” (5 points). The answers correspond to a scale of face drawings ranging from extremely negative to extremely positive. The process consisted of initial translation, back-translation, expert committee review, and pretesting. Results: The first revised version was applied to 32 children aged 5 to 12 years, 16 from the city of Governador Valadares, Brazil (southeastern region) and 16 from the city of Pelotas, Brazil (southern region). In the first pretest, Item 5 was misunderstood by 6.25% of children in the southern region; Item 6 by 6.25% in both regions; Items 7 and 8 by 87.5% and 100% of those from the southeastern region, respectively, and by 12.5% and 25% of those from the southern region, respectively. Items 7 and 8 were modified by the expert committee, and the second revised version was applied to 32 children, 16 from each region. The only misunderstood items were 4 and 5, both by a 7-year-old boy in Governador Valadares. Conclusion: The Brazilian Portuguese version of the MCDASf was well understood by the sample of children.

Abstract Introduction Adenotonsillectomy is the first-line treatment for obstructive sleep apnea secondary to adenotonsillar hypertrophy in children. The physical benefits of this surgery are well known as well as its impact on the quality of life (QoL), mainly according to short-term evaluations. However, the long-term effects of this surgery are still unclear. Objective To evaluate the long-term impact of adenotonsillectomy on the QoL of children with sleep-disordered breathing (SDB). Method This was a prospective non-controlled study. Children between 3 and 13 years of age with symptoms of SDB for whom adenotonsillectomy had been indicated were included. Children with comorbities were excluded. Quality of life was evaluated using the obstructive sleep apnea questionnaire (OSA-18), which was completed prior to, 10 days, 6 months, 12 months and, at least, 18 months after the procedure. For statistical analysis, p-values lower than 0.05 were defined as statistically significant. Results A total of 31 patients were enrolled in the study. The average age was 5.2 years, and 16 patients were male. The OSA-18 scores improved after the procedure in all domains, and this result was maintained until the last evaluation, done 22 ± 3 months after the procedure. Improvement in each domain was not superior to achieved in other domains. No correlation was found between tonsil or adenoid size and OSA-18 scores. Conclusion This is the largest prospective study that evaluated the long-term effects of the surgery on the QoL of children with SDB using the OSA-18. Our results show adenotonsillectomy has a positive impact in children's QoL.

Abstract This study aimed to assess the discriminant validity of the Caries Assessment Spectrum and Treatment (CAST) at different thresholds, compared with the Decayed, Missing, and Filled Teeth Index (dmf) instrument, to discriminate caries risk factors. A cross-sectional study was conducted including children aged 2-5 years from preschools in Southern Brazil. Parents answered a questionnaire, and children were clinically examined using the CAST instrument and, in the following weeks, using the dmf index. Two caries thresholds were adopted for CAST: caries in dentin (CAST4-7/CAST2,4-8) and enamel caries (CAST3-7/CAST2-8). Poisson regression was used in the analysis (p < 0.05). A total of 200 children were included. The prevalence of caries was 47.0% with dmf, 42.5% with CAST4-7, and 77.5% with CAST3-7. When the outcome was caries prevalence, CAST4-7 discriminated between sexes, household crowding, and dental pain, and CAST3-7 discriminated age and family income, while the dmf was associated with dental pain. When experience of caries was the outcome, all the criteria discriminated between sexes, age, family income, household overcrowding, visible dental plaque, and dental pain, while dmf and CAST2-8 also discriminated maternal schooling. The CAST discriminated caries risk factors similar to the dmf index when caries experience was the outcome. When prevalence was considered, CAST was able to discriminate for more individual characteristics than dmf.

ABSTRACT Objective: To evaluate and discuss the prevention and management of dental trauma in primary teeth during the COVID-19 pandemic. Material and Methods: Critic literature review, searching electronic databases and Google for articles and guidelines published in English that described prevention and management of dental trauma in primary dentition during the pandemic of COVID-19. Results: 5 publications regarding management and 1 leaflet about prevention for parents were identified. Urgent care is required when the child presents tooth fracture resulting in pain or causing soft tissue trauma and luxation affecting bite. Avulsed teeth should not be replanted and advice and self-help may be sufficient in some situations. Instructions about soft diet and hygiene must be provided. Remote consults are recommended for non-urgent situations and during follow-up to evaluate the presence of sequelae. Aerosol generating procedures should be avoided and, in cases of poor prognosis, extraction is recommended to prevent recurring visits to the dental office. Conclusion: During COVID-19 pandemic, remote consults should be recommended to evaluate traumatic dental injuries in primary dentition. Follow-up should not be neglected and may be performed through remote consultation.
