ABSTRACT Objective: To evaluate the changes in the work routine of Brazilian pediatric dentists (PD) during the COVID-19 pandemic. Material and Methods: Dentists specializing in pediatric dentistry, working in public or private services, and attending children or adolescents were included. Data collection was performed through a self-administered online questionnaire. Demographic information such as gender, age, work experience time, city size, and place of work was collected; if specific preventive measures were adopted during the pandemic; if there was an increase in service prices and additional costs; and how did the search for urgent or elective dental care take place during 2020 and 2021. A descriptive analysis was performed. Results: A total of 270 PD answered the questionnaire, of which 52.6% interrupted elective care during the pandemic, more than half (51.1%) reduced the number of patients per shift, and more than 70% increased weekly hours. Regarding the financial aspect, 94.7% of participants reported having additional costs, and 51.8% increased the cost of their appointments. In 2020, 72.0% reported a decrease in searches for elective appointments and 58.7% an increase for urgent care. Conclusion: The COVID-19 pandemic affected the search for appointments and the routine of Brazilian PD. For many, the potential financial impact was due to additional costs, periods without patients, and price correction of appointments.

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 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 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.

Resumo Fraturas coronorradiculares em dentes decíduos são raras, com uma ampla variação de padrões que dificultam o diagnóstico e tratamento. O objetivo deste estudo foi apresentar uma série de casos de fraturas coronorradiculares na dentição decídua de crianças atendidas em um centro de referência. O estudo acompanhou 28 casos de fratura coronorradicular em 26 crianças, representando 4% do número total de participantes ao longo de 11 anos no serviço de referência na Universidade Federal de Pelotas. Na maioria dos casos, o incisivo central superior (85,7%) foi o mais envolvido. Na coroa, 57,1% dos casos tiveram linha de fratura simples, e 42,9% tiveram múltiplas linhas. As linhas simples predominaram na raiz (89,3%). Nos casos com linhas de fratura simples na coroa, 37,6% foram submetidos à extração total, 31,2% necessitaram de extração parcial e 31,2% de pulpectomia. A maioria dos dentes com múltiplas linhas de fratura na coroa, a extração total foi realizada (91,7%). Todos os casos foram acompanhados até a erupção do dente permanente sucessor, e todos os pacientes tiveram resultados favoráveis.

Abstract Crown-root fractures in primary teeth are rare, with a wide variation of patterns that make diagnosis and treatment difficult. The aim of this study was to present a case series of crown-root fractures in primary teeth of children who attended a reference center. The study followed 28 cases of crown-root fractures in 26 children, representing 4% of the total number of attendees over 11 years of reference service at the Universidade Federal de Pelotas, Pelotas, Brazil. In most cases, the maxillary central incisors (85.7%) were involved. In the crown, 57.1% of the cases had a simple line of fracture, and 42.9% had multiple lines. Simple lines predominated in the root (89.3%). In cases with simple fracture lines in the crown, 37.6% underwent a total extraction, 31.2% required a partial extraction and 31.2% underwent pulpectomy. In most teeth with multiple lines of fractures in the crown, total extraction was performed (91.7%) All cases were followed-up until the eruption of the permanent successor tooth, and all patients had favorable outcomes.
