RESUMO

BACKGROUND: To evaluate whether the prevalence of traumatic dental injuries (TDIs) in permanent anterior teeth among school children is associated with sleep behaviours and disorders. METHODS: A cross-sectional study was carried out with a representative sample of schoolchildren aged 8 to 10 years (n = 1402) from Florianopolis, Brazil. Clinical examinations for TDIs were performed according to the classification proposed by Andreasen. Parents/caregivers completed a questionnaire addressing sociodemographic characteristics and sleep behaviours/disorders (sleep duration, insomnia, sleep rhythmic movement, snoring, and signs of sleep apnoea). Descriptive analysis and Poisson regression were performed. RESULTS: The prevalence of TDIs was 10.9%. Insomnia was observed in 3.0% of the children, snoring in 42.8%, sleep rhythmic movement in 27.9%, and signs of obstructive sleep apnoea in 33.6% of the schoolchildren. Most children (75.2%) slept less than eight hours a day. The prevalence of TDIs was higher among schoolchildren with an increased overjet (PR: 1.65; 95% CI: 1.15-2.35; P < 0.01), after adjusting for monthly family income, caregiver's schooling, and sleep behaviours. The prevalence of TDIs was not associated with sleep behaviours/disorders. CONCLUSIONS: Parent-reported sleep disorders such as insomnia, sleep rhythmic movement, snoring and signs of sleep apnoea were not associated with the prevalence of TDIs in schoolchildren. © 2024 Australian Dental Association.

RESUMO

Traumatic dental injuries (TDI) are common in children due learning to walk and lack of balance that leads to falls. Luxation is the trauma that occurs most frequently in the deciduous, being that the intrusive and the avulsive are the ones that cause more damage to the permanent successors. The potential to cause disturbances to the developing permanent germ is high due to anatomical proximity and depends on age, direction of intrusion, severity and treatment. The consequences to the permanent range from hypocalcifications of enamel to retention of the permanent germ. In this case, the developmental disturbance of the tooth 21 presenting with acute dentoalveolar abscess was a result of a three-degree intrusive luxation of the deciduous predecessor. The tooth 61 was misdiagnosed initially as avulsion, but it was a total intrusion as uncovered after a radiographic examination that showed an image suggestive of the presence of the deciduous tooth. The deciduous was extracted along with his permanent successor through outpatient procedure under antibiotic coverage and local anesthesia. The macro and microscopic analysis of the piece evidenced the presence of elements 21 and 61 closely united, as well as alterations provoked in both. There was remission of the infectious process and after 7 days it was verified the correct healing of the surgical wound. The radical outcome of this case emphasizes the relevance of appropriate clinical support as soon as possible in all TDI.

RESUMO

Objective: To evaluate the quality, reliability and content of YouTube videos in Portuguese about dental trauma. Method: An infodemiological study was developed in which the first 60 videos found on YouTube with the terms "dental traumatism", "dental trauma" and "broken tooth" were analyzed. Repeated videos, longer than one hour, in a language other than Portuguese, not intended for the lay public, resolution of questions, songs, interviews, shorts, and other subjects were excluded. The content of the videos was rated using a 23-point scale that classified them into low, moderate, and high content. Reliability was assessed using the modified DISCERN scale and the overall quality was assessed using the Global Quality Score (GQS) scale. The numbers of likes, dislikes, comments and engagement were also accounted. Data were analyzed by Mann-Whitney and Spearman's correlation test (α= 5%). Result: A total of 55 videos were included in the study. Most were posted by healthcare professionals (92.7%) and just over half (63.7%) were of good overall quality. There were moderate, positive, and statistically significant correlations between DISCERN and GQS scores (r=0.454), duration (r=0.575), and trauma content (r=0.510). Overall quality correlated moderately, positively, and significantly with content scores (r=0.604) and video length (r=0.467). Conclusion: A significant proportion of Portuguese videos on YouTube about dental trauma had low content, quality and reliability information.

Objetivo: Avaliar a qualidade, a confiabilidade e o conteúdo de vídeos do YouTube na língua portuguesa sobre traumatismo dentário. Método: Um estudo infodemiológico foi desenvolvido a partir de uma busca no YouTube e os 60 primeiros vídeos encontrados com cada um dos termos "traumatismo dentário", "trauma dental" e "dente quebrado" foram analisados. Vídeos repetidos, com mais de uma hora de duração, em outro idioma, não destinados ao público leigo, resolução de questões, músicas, entrevistas, shorts, e vídeos sobre outras temáticas foram excluídos. O conteúdo dos vídeos foi avaliado usando uma escala de 23 pontos que os classificou em baixo, moderado e alto conteúdo. A confiabilidade foi avaliada utilizando a escala DISCERN modificada e a qualidade geral foi avaliada com a escala Global Quality Score (GQS). Também foram contabilizados os números de curtidas, dislikes, comentários e engajamento. Os dados foram analisados pelos testes de Mann-Whitney e correlação de Spearman (α = 5%). Resultado: 55 vídeos foram incluídos no estudo. A maioria foi postada por profissionais de saúde (92,7%) e pouco mais da metade (63,7%) foi de qualidade geral boa. Houve uma correlação moderada, positiva e estatisticamente significativa entre os escores do DISCERN e do GQS (r = 0,454), duração (r = 0,575) e conteúdo de trauma (r = 0,510). A qualidade geral se correlacionou de forma moderada, positiva e significativa com os escores de conteúdo (r = 0,604) e com a duração do vídeo (r = 0,467). Conclusão:Uma proporção de vídeos em Português presentes no YouTube sobre traumatismo dentário possui informações de baixo conteúdo, qualidade e confiabilidade.

RESUMO

BACKGROUND/AIMS: The level of knowledge about traumatic dental injuries (TDI) of lay people from a national point of view has never been studied and there is currently a lack of validated research instruments on this issue. The present study aims to develop and validate a questionnaire (TDI-Q) to assess the knowledge of lay people about TDI, including participants from the five regions of Brazil. MATERIAL AND METHODS: TDI-Q was drafted, in Brazilian Portuguese, based on the recommendations of the International Association of Dental Traumatology (IADT). Before its application, TDI-Q was evaluated by dentists, lay people, linguists, and psychometrists. The questionnaire was applied to measure temporal stability at two distinct times, with an interval of 15-20 days between the two applications: test (n = 110) and retest (n = 50). The presence of floor and ceiling effects were investigated by analyzing the frequency of responses of the questionnaire; convergent construct validity was tested through Spearman's correlation; the Mann-Whitney test was applied to discriminant construct validity. Temporal stability and internal consistency were evaluated through intraclass correlation coefficient and Cronbach's alpha, respectively. RESULTS: The floor and ceiling effects were not observed (0.9% and 2.7%, respectively); convergent validity analysis indicated a positive and strong correlation (r = 0.50; p < .001). Significant discriminant construct validity (p < .05) was observed. Satisfactory internal consistency (α = 0.7) and temporal stability (ICC = 0.82, p < .001) were also achieved. CONCLUSION: TDI-Q proved to have good psychometric properties and to be a reliable tool for evaluating the knowledge of lay people regarding TDI in the Brazilian population.

RESUMO

BACKGROUND/AIM: Childhood dental trauma poses a prevalent concern, and the limited knowledge of lay caregivers toward the needed immediate actions can adversely affect a child's well-being. This study aimed to create and validate an educational comic book for lay individuals, designed to guide immediate actions in dental trauma cases, and assess its effects toward enhancing reader knowledge. METHODOLOGY: The four-stage study involved: (1) Literature review and script development; (2) Version 1 of the comic book creation (including illustrations, layout, and design) and Flesch Readability Index (FI) calculation; (3) Version 1 validation by expert judges, assessed by the Content Validity Index (CVI); (4) Version 1 refinement based on the judges' feedback, recalculation of FI, and a pilot test (CVI) involving lay individuals who validated the final material (Version 2). The validation process involved 67 participants, including 13 specialist judges and 54 elementary school teachers. RESULTS: The CVI for Version 1 was calculated at 0.89 (89%), indicating a favorable level of agreement on the evaluated criteria. The FI was determined as 91.1%, indicating a high level of readability. The FI for Version 2 was 92.1% (indicating a very easy level of comprehension). The CVI calculated for the target audience after the pilot test was 0.99 (99%), denoting a substantial agreement among the participants. In assessing the level of knowledge, a significant increase was observed in the rate of correct answers after the comic book was read by lay individuals (p < 0.05), inasmuch as the percentage rose from 50.5% before to 81.2% after reading it. CONCLUSION: The educational comic book proved valid in terms of readability, appearance, and content. Furthermore, it had a positive impact on gaining the knowledge needed to take the appropriate actions, thus making it a valuable tool for guiding the lay population in cases of dental trauma.

RESUMO

Individuals with cerebral palsy (CP) may have cognitive, sensitive, behavioral, communicative, and convulsive disorders. Because defensive reflexes are reduced by CP, the risk of orofacial trauma is greater in these individuals. This study aimed to evaluate the prevalence of orofacial injuries resulting from trauma in patients with CP. This review was reported according to preferred reporting items for systematic reviews and meta-analyses (PRISMA) and registered in the International Prospective Register of Systematic Reviews (PROSPERO-CRD42022293570). The search was performed for articles published until January 2023 in Embase, Latin American and Caribbean Literature on Health Sciences (LILACS), PubMed/Medline, Scopus, and Web of Science databases. Gray literature was also consulted through Google Scholar, OpenGrey, ProQuest Dissertations, and Theses. Studies in which orofacial injuries due to trauma were prevalent in individuals with CP were included. The risk of bias was assessed using the Joanna Briggs Institute Critical Appraisal Tool. Additionally, a random-effects meta-analysis was conducted. Twelve studies were included in the synthesis, of which nine presented a low risk of bias and three presented a moderate risk. When considering the general prevalence of orofacial injuries in patients with CP, a prevalence of 34% [95% CI = 18%-52%; I2 = 98%] was observed, with enamel and dentin fractures being the most common orofacial injuries. Approximately one in three patients with CP showed at least one type of orofacial injury involving dental trauma. There is a lack of literature assessing the prevalence of these traumas in soft tissues and the evidence for this outcome remains uncertain.

RESUMO

Abstract This systematic review aimed to answer the following question: What is the estimated prevalence of pulp canal obliteration in subtypes of traumatic dental injury (TDI) in deciduous and permanent teeth? The searches were conducted in PubMed, Embase, Scopus, Web of Science, LILACS, Grey Literature, and Google Scholar, and complemented by a manual search, until April 16th, 2023. Observational studies were selected based on population, exposure, and outcome (PEO) (P, deciduous or permanent teeth; E, TDI; O, pulp canal obliteration). Two reviewers (kappa 0.90) applied the eligibility criteria, extracted qualitative data, and assessed the methodological quality using the Newcastle-Ottawa tool. A meta-analysis was performed using MedCalc 17.2. Thirty-four articles were selected after screening. The methodological quality was moderate to high. The estimated prevalence of pulp canal obliteration was 27.6% (95%CI: 18.7-37.7) and 21.9% (95%CI:16.0-28.4), for permanent and deciduous teeth, respectively. Considering the TDI subtypes, the prevalence of pulp canal obliteration was higher in root fractures of the permanent teeth (78.6 %, 95%CI: 62.8-90.9) and lateral luxation injuries in deciduous teeth (29.4%, 95%CI:19.1-41.0). Our review of 34 articles of moderate and high methodological quality found that the prevalence of pulpal canal obliteration ranges from 21.9% to 27.6%. Pulp canal obliteration was most frequently detected following lateral luxation injuries of the deciduous teeth and root fractures of the permanent teeth (PROSPERO CRD42020179438).

RESUMO

Abstract Objective: To evaluate the knowledge of Physical Education students about tooth avulsion (TA) in both dentitions before and after receiving an informative leaflet (IL). Material and Methods: The questionnaire contained information about TA in dentition and its management and was applied to the Physical Education students before and after reading an IL. Results: A total of 118 students, 96.61%, attended a first aid course, and 17.80% received information about TA. Most students (88.98%) never had an experience with TA, and 90.68% considered its management important. The other questions, before and after reading the IL, respectively, were: would not perform deciduous tooth replantation (42%; 88%); knew how to handle the avulsed permanent tooth (APT) (38%; 92%); knew how to clean the APT (50%; 99%); knew that permanent tooth replantation (PTR) must be immediate (15%; 95%); knew the ideal time to seek for the dentist right after TA without performing PTR (6%; 83%); knew how to store APT (31%; 97%). Conclusion: The knowledge of Physical Education students in this research revealed a limited understanding of dental tooth avulsion. After receiving an informative leaflet, the students showed a significant improvement in knowledge about traumatic avulsion management, including tooth replantation and proper actions.

RESUMO

ABSTRACT Objective: To determine the prevalence and risk factors associated with dental caries in Brazilian preschool children aged 2 to 5 years. Material and Methods: The following independent variables were evaluated: dental caries, dental trauma, and malocclusions. Data were analyzed using the Mann-Whitney test and Poisson regression (p<0.05). Results: The prevalence of dental caries in preschoolers was 55.1%. Child age, family income, maternal education, and tooth color alteration from trauma were significantly associated with dental caries (p<0.05). The final adjusted multivariate model showed a significant association between maternal education and dental caries; children of mothers with low education were 1.89 times more likely to have caries (PR: 1.89; 95%CI: 1.40-2.55) (p<0.01). Children with tooth color change from trauma were more likely to have dental caries (PR: 1.69; 95%CI: 1.22-2.34 (p=0.001). Conclusion: Child age, family income, maternal education, tooth discoloration and discoloration color are risk factors for the development of caries disease in children. Also, children of mothers with low educational levels have a higher chance of developing dental caries.

RESUMO

ABSTRACT Dental trauma can happen at any stage of life; however, it is very common in preschool and school aged children. Dislocation injuries in the primary dentition are the most commonly described traumatic dental injuries in the literature. Tooth displacement in the primary dentition is favored due to the greater porosity and resilience of the alveolar bone. Through the study of a clinical case, this article presents the clinical conduct performed in the case of trauma of lateral dislocation with involvement of a fracture of the buccal bone plate in order to assist the clinical practice of dentists who care for children. The treatment carried out in this clinical case study took into account the magnitude of the displacement, the degree of development of the tooth and its relationship with the permanent germ, the length of time since the trauma, and the degree of cooperation of the child in the face of the suggested treatment. This treatment does not only involve emergency intervention; the patient must undergo a radiographic clinical follow-up and control after 30, 60 and 120 days, as well as annually, until the Exfoliation of the deciduous tooth. The child's health was restored aesthetically and functionally.

RESUMO Traumatismos dentários podem acontecer em qualquer fase da vida, entretanto, é muito comum em crianças na idade pré-escolar e escolar. As lesões de luxação na dentição decídua são as lesões dentárias traumáticas mais comumente descritas na literatura. O deslocamento dentário na dentição decídua é favorecido devido à maior porosidade e resiliência do osso alveolar. Através do relato de caso clínico, o artigo apresenta a conduta clínica realizada diante um trauma de luxação lateral com acometimento de fratura de tábua óssea vestibular no intuito de auxiliar a prática clínica de cirurgiões-dentistas que atendem crianças. O tratamento realizado neste caso clínico levou em consideração a magnitude do deslocamento, o grau de desenvolvimento do elemento dentário e sua relação com o germe do permanente, o tempo de procura após o trauma e o grau de cooperação da criança diante o tratamento sugerido. O tratamento não envolve apenas a intervenção de urgência, o paciente deve passar por um acompanhamento e controle clínico radiográfico depois de 30, 60 e 120 dias e anualmente até a Esfoliação do dente decíduo. Pôde-se verificar que foi restabelecida a saúde da criança no aspecto estético e funcional.

RESUMO

ABSTRACT Objective: To assess dentists' knowledge from Minas Gerais, Brazil, about dentoalveolar trauma (DT) and their experiences during the COVID-19 pandemic. Material and Methods: An online questionnaire with 34 questions was applied to collect personal data, professional training, self-assessment of experience/knowledge about DT, experience in care provided during the social distancing, and knowledge/conduct. The specific responses were evaluated based on the guidelines of the International Association of Dental Traumatology (IADT). Descriptive analysis and Pearson's chi-square test were performed. The level of significance was set at p≤0.05. Results: Most professionals (97.7%) had received information on DT, and only 4.6% of the participants considered their knowledge poor or very poor. However, 92.7% felt the need for more information on the subject. Regarding experiences during the pandemic, 55.7% provided trauma care during that period. Forty percent of the consultations were performed in person, and 33.3% of the professionals noted an increase in cases during the pandemic; 56.6% reported that the frequency did not change. The overall mean number of correct answers about DT was 5.29±2.11, indicating an acceptable level of knowledge. The mean percentage of hits for the specific questions was 44.1%. Conclusion: Although the level of knowledge of the dentists evaluated was acceptable, some aspects were deficient, with the need for more information about the IADT guidelines.

RESUMO

Objetivo: O presente estudo teve como objetivo avaliar o perfil dos pacientes atendidos em um centro de referência de traumatismos dentários na dentição decídua, identificando as características sociodemográficas, frequência, tipos de lesões traumáticas e tratamentos realizados. Métodos:Trata-se de um estudo retrospectivo com prontuários odontológicos de crianças de 6 a 60 meses de idade atendidas na Clínica de Traumatismo na Dentição Decídua da FAO/UFMG no período de 2007 a 2019. Foram analisadas características das lesões traumáticas, da criança, atendimento imediato (2h após o trauma) e condições socioeconômicas. A análise dos dados foi realizada de maneira descritiva e consistiu na distribuição de frequência das variáveis. Resultados:Entre os 610 prontuários odontológicos, 365 crianças (59,8%) eram do sexo masculino; 335 (54,9%) tinham 3 anos de idade ou menos, 446 (73,1%) eram de baixa renda e 335 (54,9%) das mães estudaram até o ensino médio. Lesões aos tecidos duros dentários apresentaram a maior frequência em crianças com 3 anos de idade ou menos (60,4%), entretanto, após os 3 anos de idade, as lesões mais frequentes foram lesões aos tecidos de sustentação (48,0%). Dentre a classificação de lesões aos tecidos duros dentários, a trinca e/ou fratura de esmalte foi a lesão mais frequente (15,0%). A luxação intrusiva foi o trauma mais frequente nos tecidos de sustentação (11,2%) e lesão em gengiva foi mais frequente dentre lesões nos tecidos moles (9,5%). Em geral, 212 crianças (34,8%) buscaram atendimento em um intervalo menor ou igual a duas horas após o trauma. A exodontia foi o tratamento mais realizado: em casos de lesões aos tecidos de sustentação (47,1%), seguido do mantenedor de espaço (24,3%). Em tecidos duros dentários a exodontia também foi o tratamento mais frequente (50,7%), seguido de restauração e mantenedor de espaço (18,0%). Conclusão: Conclui-se que a maioria dos traumatismos dentários na dentição decídua foram em meninos com menos de 3 anos e as lesões mais comuns foram trincas/fratura de esmalte, seguidas das luxações intrusivas.

Aim: The aim of the present study was to evaluate the profile and characteristics of patients treated at a dental trauma reference center, and identifying frequency, types of traumatic injuries and treatments performed. Methods: This retrospective study was carried out with dental records of children aged 6 to 60 months attended at the Primary Dental Trauma Clinic of FAO/UFMG between 2007 and 2019. Characteristics of the child and traumatic dental injuries, immediate care (2 hours after the trauma) and socioeconomic status were analyzed.

RESUMO

Aim: to evaluate the cyclists' profile and the frequency of dental trauma associated with cycling in a southern city in Brazil. Materials and Methods: a questionnaire was applied to 234 cyclists with at least 18 years old. The variables of interests were: sociodemographic data, data related to the profile of users, and data on the occurrence of all traumas and dental traumas. Descriptive and inferential statistical analyses were carried out (α=5%). Results: The mean age of participants was 31.38 ± 11.6 years, ranging from 14 to 67 years. The majority of the participants were male (62.8%), had attended higher education (45.7%), and had incomes equivalent to 1 to 3 times the minimum wage (39.3%). The main reason given for riding a bicycle was leisure (35.9%). Users of their own bicycles had fewer items of mandatory safety equipment fitted to their bicycles than users of rented bicycles (Student's t test, P<0.0001). However, study participants riding their own bicycles wore personal protective equipment more frequently than renters (Student's t test, P<0.0001). Moreover, 33.7% of the respondents reported having suffered an accident, and 25% had traumatized some part of the body. Among those who reported traumas, 20% (4/20) had suffered traumas to hard dental tissues and supporting structures. Discussion: Dental trauma was not frequent in a population predominantly from an urban area that uses bicycles, especially for leisure, despite the prevalence of accidents involving bicycle use. Conclusion: Health education campaigns should emphasize the importance of personal protective equipment for cyclists and of safety items fitted to bicycles, whether cyclists' own or rented.

Objetivo: avaliar o perfil dos ciclistas e a frequência de traumatismo dentário associado ao ciclismo em uma cidade do sul do Brasil. Materiais e Métodos: aplicou-se um questionário a 234 ciclistas com idade mínima de 18 anos. As variáveis ​​de interesse foram: dados sociodemográficos, dados relacionados ao perfil dos usuários e dados sobre a ocorrência de todos os traumatismos e traumas dentários. Foram realizadas análises estatísticas descritivas e inferenciais (α=5%). Resultados: A idade média dos participantes era de 31,38 ±11,6 anos, variando de 14 a 67 anos. A maioria dos participantes era do sexo masculino (62,8%), tinha curso superior (45,7%) e renda equivalente a 1 a 3 salários mínimos (39,3%). O principal motivo para andar de bicicleta foi lazer (35,9%). Usuários de suas próprias bicicletas tinham menos itens de equipamentos de segurança obrigatórios instalados do que os usuários de bicicletas alugadas (teste t de Student, P<0,0001). Porém, participantes do estudo que andavam em sua própria bicicleta usavam equipamentos de proteção individual mais frequentemente do que os locatários (teste t de Student, P<0,0001). Ainda, 33,7% dos entrevistados relataram ter sofrido algum acidente e 25% traumatizado alguma parte do corpo. Entre os que relataram traumatismos, 20% (4/20) sofreram traumas em tecidos duros dentais e estruturas de suporte. Discussão: O traumatismo dentário não foi frequente em uma população predominantemente de área urbana que utiliza bicicletas, principalmente para lazer, apesar da prevalência de acidentes envolvendo o uso de bicicletas. Conclusão: As campanhas de educação em saúde devem enfatizar a importância dos equipamentos de proteção individual dos ciclistas e dos itens de segurança instalados nas bicicletas, sejam elas próprias ou alugadas.

RESUMO

INTRODUCTION: Knowledge of bibliometric indices on the avulsion of permanent teeth can help researchers to identify gaps in the literature. The aim of this study was to analyze the bibliometric characteristics of the 100 most-cited articles on the avulsion of permanent teeth. MATERIALS AND METHODS: Two researchers conducted an unfiltered search in the Core Collection section of the Web of Science (WoS-CC) database. The following data were extracted: position in the citation list, total number and density of citations, title, authors, institution, country, year of publication, journal, keywords, study design, tooth storage medium, and other topics of interest. Bibliometric networks were generated and analyzed using the VOSviewer software. Descriptive analysis and a Poisson regression analysis were performed (P < .05). RESULTS: The number of citations per article varied between 31 and 407. The average was 70.05, and 13 articles received more than 100 citations. J.O. Andreasen (n = 13) and M. Trope (n = 15) were the authors who contributed most often to publications. The United States was the country with the highest number of articles (n = 31). Authors associated with the University of Copenhagen, Denmark (n = 9) and University of North Carolina, USA (n = 10) showed higher productivity. In vitro/animal model studies were the most frequent study designs (n = 50), and the most-discussed topic of interest was prognosis (n = 47). There was strong clustering among 13 research groups. CONCLUSION: Observational studies, published by authors from Europe and about prognosis or treatment presented more citation ratio in WoS-CC. Clinical studies on permanent tooth avulsion are needed to increase the quality of scientific evidence and provide insights for health professionals and public policy makers.

RESUMO

O objetivo deste estudo quantitativo, transversal, retrospectivo e descritivo é conhecer a prevalência e a distribuição de traumatismo dentário (TD) em dois hospitais escola do Paraná, entre 2013 e 2021. Os dados (variáveis sociodemográficas; Classificação Internacional de Doenças; tipo e motivo do TD; número de dentes envolvidos e momento da ocorrência do trauma) foram extraídos dos prontuários eletrônicos dos pacientes com TD, por dois pesquisadores utilizando ficha padronizada, e descritos por frequências absolutas e relativas. Dentre 1.216 prontuários analisados, apenas 51 evidenciaram TD. Os homens (n=41/80,4%) representaram a maior parte dos pacientes. A fratura de coroa foi o tipo de TD mais encontrado (n=13/25,5%) e a queda, a maior motivação para os eventos (n=18/35,3%). A maior parte dos TD ocorreu antes da internação (n=46/90,2%) e 33 pacientes (64,7%) apresentaram até dois dentes acometidos por TD. Em razão do número reduzido de prontuários encontrados, sugere-se que estejam ocorrendo subnotificações dos casos de TD nos hospitais pesquisados. A inserção recente do cirurgião-dentista no ambiente hospitalar, associada à carência técnica de profissionais da equipe para a identificação de TD, e a análise específica de traumas dentários, sem a inclusão de eventos faciais, podem estar atreladas a essa subnotificação...

The objective of this quantitative, cross-sectional, retrospective and descriptive study is to know the prevalence and distribution of dental trauma (DT) in two teaching hospitals in Paraná, between 2013 and 2021. Data (sociodemographic variables; International Classification of Diseases; type and reason of the DT; number of teeth involved and time of trauma occurrence) were extracted from the electronic medical records of patients with DT, by two researchers using a standardized form, and described by absolute and relative frequencies. Among 1,216 medical records analyzed, only 51 showed DT. Men (n=41/80.4%) represented the majority of patients. Crown fracture was the most common type of DT (n=13/25.5%) and falls were the greatest motivation for the events (n=18/35.3%). Most DTs occurred before admission (n=46/90.2%) and 33 patients (64.7%) had up to two teeth affected by DTs. Due to the small number of medical records found, it is suggested that there are underreporting of DT cases in the surveyed hospitals. The recent insertion of dentists in the hospital environment, associated with the technical lack of team professionals to identify DT, and the specific analysis of dental trauma, without the inclusion of facial events, may be linked to this underreporting...

RESUMO

Objective: to analyze, through literature review, the available literature on orthodontic treatment in traumatized permanent teeth. Methods: A literature search was performed in electronic databases (PubMed and SciELO) using the descriptors [tooth injuries] OR [injuries, teeth] OR [injury, teeth] OR [teeth injury] OR [injuries, tooth] OR [injury, tooth] OR [tooth injury] OR [teeth injuries] AND [orthodontics]. Observational studies and clinical trials were included, narrative reviews, laboratory and in vitro studies, case reports and series as well as articles that presented abstracts written in languages other than Portuguese, English and Spanish were excluded from the study. Two reviewers considered the eligibility, the risk of bias of the analyzed data and the qualitative synthesis of the studies included. A total of 1,322 references were found and 4 articles met all inclusion criteria and were included in the qualitative analysis. Some consequences like pulp necrosis and root resorption have been highlighted and trauma severity should be considered when orthodontically intervening in previously traumatized teeth. Final considerations: The traumatized teeth can be orthodontically treated as long as the time of tissue reorganization is respected, and the pull and periodontal conditions are followed up.(AU)

Objetivos: analisar, por meio de revisão de literatura, a respeito do tratamento ortodôntico em dentes permanentes traumatizados. Metodologia: Uma pesquisa bibliográfica foi realizada em bancos de dados eletrônicos (PubMed e SciELO) usando os descritores [tooth injuries] ou [injuries, teeth] ou [injury, teeth] ou [teeth injury] ou [injuries, tooth] ou [injury, tooth] ou [tooth injury] ou [teeth injuries] e [orthodontics]. Foram incluídos estudos observacionais e ensaios clínicos, revisões narrativas, estudos laboratoriais e in vitro, relatos de casos e séries, bem como artigos que apresentassem resumos redigidos em idiomas diferentes do português, inglês e espanhol foram excluídos do estudo. Dois revisores consideraram a elegibilidade, o risco de viés dos dados analisados e a síntese qualitativa dos estudos incluídos. Foram encontradas 1.322 referências e 4 artigos atenderam a todos os critérios de inclusão e foram incluídos na análise qualitativa. Algumas consequências como necrose pulpar e reabsorção radicular têm sido destacadas e a gravidade do trauma deve ser considerada na intervenção ortodôntica em dentes previamente traumatizados. Considerações finais: Os estudos incluídos nesta revisão sugerem que dentes traumatizados podem ser tratados ortodônticamente desde que respeitado o tempo de reorganização tecidual e acompanhadas as condições pulpares e periodontais.(AU)

RESUMO

Objetivo: verificar o conhecimento de acadêmicos de Odontologia de uma instituição de ensino superior da Paraíba acerca da avulsão dentária. Métodos: foi realizado um estudo transversal, no qual 64 acadêmicos responderam um formulário com perguntas objetivas relativas a dados sociodemográficos, período de formação do curso e conhecimento e condutas em casos de avulsão dentária. Foi realizada análise descritiva de frequência absoluta e relativa dos dados (SPSS, v. 20.0). Resultados: a maioria dos acadêmicos recebeu informações sobre avulsão dentária em aulas ministradas no curso (86%) e indicaria a irrigação com soro fisiológico seguida de reimplante quando da ocorrência do trauma há menos de uma hora (64,1%) e há mais de uma hora (43,8%). O tratamento endodôntico foi indicado, independentemente do tempo do dente fora do alvéolo, por 34,4% da amostra. A contenção rígida foi a mais indicada para o dente reimplantado (48,4%) e seu tempo mínimo de proservação radiográfica respondido pela maioria dos pesquisados foi de 6 meses (48,4%). Conclusões: apesar de a maioria dos acadêmicos ter recebido informações acerca da temática, o conhecimento foi considerado insuficiente em relação a condutas referentes ao reimplante dentário, indicação do tratamento endodôntico, tipo de contenção e tempo de proservação.

Objective: to verify the knowledge of dental students from a Higher Education Institution of Paraíba about dental avulsion. Methods: a cross-sectional study was carried out, in which 64 students answered a form with objective questions regarding sociodemographic data, course period, knowledge and conduct in cases of tooth avulsion. Descriptive analysis of absolute and relative frequency of data was performed (SPSS, v. 20.0). Results: most students received information about dental avulsion during the graduation classes (86%) and would indicate irrigation with saline solution followed by reimplantation when the trauma occurred less than one hour (64.1%) and more than one hour (43.8%). Endodontic treatment was indicated, regardless of the time the tooth was out of the dental socket, according 34.4% of the sample. Rigid retention was the most indicated for the reimplanted tooth (48.4%) and six months was the minimum radiographic follow-up time answered by most students (48.4%). Conclusions: although most students have received information about the topic, the knowledge was considered insufficient in relation to some aspects of the protocols recommended for emergency care for dental avulsion, with emphasis on behaviors related to dental reimplantation, indication of endodontic treatment, type of containment and follow-up.

RESUMO

INTRODUCTION: Usually, orthodontic movements encompass children and young adult patients, which are more susceptible to the occurrence of traumatic dental injuries. It is necessary to understand whether the effects of orthodontic movements on traumatized teeth could induce pulp necrosis. The aim of this study was to answer the following question: "Do orthodontic movements of traumatized teeth induce dental pulp necrosis?". MATERIAL AND METHODS: Searches were performed for studies published up to May 11, 2023, in the MEDLINE/PubMed, Cochrane Library, Scopus, SciELO Citation Index, Web of Science, EMBASE, and Grey Literature Report databases, without restriction for language or year of publication. The revised Cochrane risk of bias tools for nonrandomized interventions (ROBINS-I) was used to assess the quality of the included studies. The overall quality of evidence was assessed through the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) tool. RESULTS: Of 2671 potentially relevant studies, five were included. Four were classified as having a moderate risk of bias and one as a serious risk of bias. It was reported a higher susceptibility to pulp necrosis in teeth subjected to orthodontic movements with history of trauma involving periodontal tissues. Additionally, orthodontic movements of traumatized teeth with total pulp obliteration had an increased risk of pulp necrosis. GRADE analysis presented a moderate certainty of evidence. CONCLUSIONS: An increased risk for pulp necrosis when traumatized teeth are subjected to orthodontic movements was verified. However, this is based on evaluations performed with subjective tests. Further well-designed studies are necessary to confirm this trend. CLINICAL RELEVANCE: Clinicians must be aware of the possibility of pulp necrosis. However, endodontic treatment is recommended when verified signs and symptoms of pulp necrosis.
