Effects of Synthetic Toll-Like Receptor 9 Ligand Molecules on Pulpal Immunomodulatory Response and Repair after Injuries.

Synthetic oligodeoxynucleotides (ODNs) containing unmethylated cytosine-phosphate-guanine (CpG) motifs (CpG-ODNs) are ligand molecules for Toll-like receptor 9 (TLR9), which is expressed by odontoblasts in vitro and dental pulp cells. This study determined the effects of CpG-ODNs on pulpal immunomodulatory response and repair following injury. Briefly, the upper right first molars of three-week-old mice were extracted, immersed in Type A (D35) or B (K3) CpG-ODN solutions (0.1 or 0.8 mM) for 30 min, and then replanted. Pulpal healing and immunomodulatory activity were assessed by hematoxylin-eosin and AZAN staining, as well as immunohistochemistry. One week following the operation, inflammatory reactions occurred in all of the experimental groups; however, re-revascularization and newly formed hard tissue deposition were observed in the pulp chamber of all groups at week 2. A positive trend in the expression of immune cell markers was observed toward the CpG-ODN groups at 0.1 mM. Our data suggest that synthetic CpG-ODN solutions at low concentrations may evoke a long-lasting macrophage-TLR9-mediated pro-inflammatory, rather than anti-inflammatory, response in the dental pulp to modulate the repair process and hard tissue formation. Further studies are needed to determine the effects of current immunomodulatory agents in vitro and in vivo and develop treatment strategies for dental tissue regeneration.

Union between deciduous and permanent as intrusive luxation sequelae: A case report.

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.

Evidence-based management of isolated dentoalveolar fractures: a systematic review.

Dentoalveolar (DA) trauma, which can involve tooth, alveolar bone, and surrounding soft tissues, is a significant dentofacial emergency. In emergency settings, physicians might lack comprehensive knowledge of timely procedures, causing delays for specialist referral. This systematic review assesses the literature on isolated DA fractures, emphasizing intervention timing and splinting techniques and duration in both children and adults. This systematic review adhered to PRISMA guidelines and involved a thorough search across PubMed, Google Scholar, Semantic Scholar, and the Cochrane Library from January 1980 to December 2022. Inclusion and exclusion criteria guided study selection, with data extraction and analysis centered on demographics, etiology, injury site, diagnostics, treatment timelines, and outcomes in pediatric (2-12 years) and adult (>12 years) populations. This review analyzed 26 studies, categorized by age into pediatrics (2-12 years) and adults (>12 years). Falls were a common etiology, primarily affecting the anterior maxilla. Immediate management involved replantation, repositioning, and splinting within 24 hours (pediatric) or 48 hours (adult). Composite resin-bonded splints were common. Endodontic treatment was done within a timeframe of 3 days to 12 weeks for children and 2-12 weeks for adults. Tailored management based on patient age, tooth development stage, time elapsed, and resource availability is essential.

Are sleep disorders associated with traumatic dental injuries in school children? A cross-sectional study.

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.

Management of traumatic dental injuries in a hemophiliac patient: A challenge! Case report with nine years follow-up.

Traumatic dental injuries (TDIs) are frequently associated with an injury pattern that requires accurate diagnosis for developing the appropriate treatment plan. When children with special healthcare needs, i.e., Hemophilia experience TDIs, managing the situation becomes a challenging task for pediatric dentists due to the requirement of a multidisciplinary approach in their care. This case report highlights the successful management of extrusive luxation injury of a young permanent tooth with an open apex in an eight-year-old male child with severe Hemophilia A. After a follow-up of nine years, the pulp showed significant healing with physiological closure of the apical foramen. The study further emphasizes that timely management of such injuries can lead to improved tooth prognosis.

Occlusal Radiographs in a Turkish Pediatric Subpopulation.

Objectives: Dental radiographs are a useful diagnostic aid in the oral health care and dental treatment of children. The most commonly used radiographs are periapical and panoramic radiographs. Occlusal radiographs are preferred in more specific cases. The aim of this study was to retrospectively evaluate the reasons for obtaining occlusal radiographs in pediatric patients. Material and methods: Occlusal radiographs of patients aged 1-13 years who attended the Pediatric Dentistry Clinic of Ondokuz Mayis University Faculty of Dentistry between 01 August 2015 and 01 August 2020 were retrospectively evaluated. Patients with syndromes and diseases that could cause cleft lip and palate and dental anomalies were not included in the study. The medical history of the 354 patients who were included in the study was provided by the automated system. Results: A total of 359 occlusal radiographs from these patients were analysed. The number of male patients included in the study was 208 and the number of female patients was 146. Occlusal radiographs of the maxilla of 312 patients were taken, of the mandible of 37 patients, and both the upper and lower jaws of 5 patients. It was found that occlusal radiographs were taken mostly for dental trauma in the permanent dentition (156), injuries in the primary dentition (68) and for the diagnosis of dental anomalies (57). Conclusions: Occlusal radiographs are taken for specific situations in pediatric dentistry and are particularly useful in the detection and diagnosis of primary and permanent tooth injuries.

Awareness about emergency management of avulsed tooth among intern dentists-a cross-sectional observational study.

Tooth avulsion is a frequently encountered dental emergency. Children are commonly reported group due to frequent sports activities, trauma, accidents and falls. Prompt emergency management is vital for long term success and to avoid morbidity. The study was aimed to assess the understanding of intern dentists about the emergency handling of avulsed teeth cases as mostly they are first responders among health care personnel. In this study a fourteen-item questionnaire with predefined responses was shared as online Google survey form with intern dentists of 5 different dental teaching hospitals of Islamabad, Pakistan. The duration of the study was 6 months (01 March 2022 to 31 August 2022). The questions were intended to collect personal information and to check level of knowledge and awareness about the management of avulsed tooth among the dental interns. The data was analyzed by statistical methods and is presented through tables and descriptive methods. In total, 152 participants completed the shared questionnaire. The vast majority (71%) of them were aware of the initial management of avulsed teeth, 49% were aware of the ideal transport medium for an avulsed tooth, (43%) were aware of the critical time for successful replantation, while (62%) had knowledge of the multiple factors responsible for the outcome of the tooth replantation. For majority of the statements, female participants had better knowledge as compared to their male counterparts. Statistically significant difference was noted for the statement "If you found the knocked-out tooth and it is dirty what will be your initial approach?" with female participants having better knowledge as compared to the male (p value = 0.005). Based on our study results, generally dental interns are well-informed but still lack expected level of awareness regarding the proper management protocol for avulsed tooth. Hence, improvement is needed regarding the effective handling of avulsed teeth cases.

Quality, reliability, and content of YouTube videos in Portuguese language about dental trauma / Qualidade, confiabilidade e conteúdo de vídeos do Youtube na língua Portuguesa sobre traumatismo dentário

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.

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.

Prevalence of orofacial injuries resulting from trauma in individuals with cerebral palsy: A systematic review and meta-analysis.

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.

Development and psychometric properties of a questionnaire about knowledge of lay people about traumatic dental injury.

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.

Validation of an educational comic book to guide conducts in situations of dental trauma.

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.

Reducing the risk of tooth injury in anterior maxillary interdental osteotomy for cleft lip and palate patients using a surgical navigation technique.

The aim of this study was to investigate the clinical feasibility of preventing tooth injury from anterior maxillary interdental osteotomy by using a surgical navigation technique. A retrospective review was conducted on cleft lip and palate patients treated with anterior maxillary osteotomy followed by distraction osteogenesis between August 2019 and May 2022. Patients operated on through image guidance were enrolled in the navigation group, while those who were operated on freehand were enrolled in the freehand group. Tooth injuries were identified on postoperative images. Linear and angular deviations of the osteotomy line were measured. Twelve patients were enrolled in the study, seven in the navigation group and five in the freehand group. Altogether, 24 osteotomy lines and 53 adjacent teeth were evaluated. The dental injury rate was 3% in the navigation group and 27% in the freehand group (P = 0.016). The average linear deviations (mean ± standard deviation) were 0.67 ± 0.30 mm and 2.05 ± 1.33 mm, respectively (P < 0.001), while the average angular deviations were 1.67 ± 0.68° and 11.41 ± 7.46°, respectively (P < 0.001). The results suggest that navigation was able to reduce the tooth injury risk compared with freehand interdental osteotomies in crowded dental arches.

Knowledge of Brazilian Dentists about Dentoalveolar Trauma Care and their Experiences during the COVID-19 Pandemic

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.

Knowledge of Physical Education Students about Tooth Avulsion Before and After Receiving an Informative Leaflet

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.

Lateral dislocation with occurrence of buccal bone plate fracture in a deciduous tooth: clinical case study / Luxação lateral com ocorrência de fratura de tábua óssea vestibular em dente decíduo: relato de caso clínico

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.

Maternal Education Level as a Risk Factor for Early Childhood Caries / Maternal Education Level as a Risk Factor for Early Childhood Caries

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.

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. Data analysis was performed descriptively using frequency distribution. Results:Of the total of 610 dental records, 365 children (59.8%) were male; 335 (54.9%) were up to 3 years old, 446 (73.1%) were low-income and 335 (54.9%) had mothers who studied up to high school. Dental hard tissue injuries were more frequent in children aged 3 years or less (60.4%), but after 3 years of age, the most frequent injuries were supporting tissue injuries (48.0%). Among dental hard tissue injuries, enamel crack and/or fracture was the most frequent injury (15.0%). Intrusive luxation was the most frequent lesion in supporting tissues injuries (11.2%) and gingival lesions was the most frequent soft tissue injuries (9.5%). Overall, 212 children (34.8%) sought care within two hours of the injury. Extraction was the most common treatment for supporting tissue injuries (44.3%), followed by space maintainers (22.8%). In dental hard tissues injuries, extraction was also the most frequent treatment (35.8%), followed by restoration (30.2%). Conclusion: In conclusion, most traumatic dental injuries in the primary dentition occurred in boys under 3 years of age, and the most common injuries were enamel cracks/fractures, followed by intrusive luxation.

Evaluation of dental trauma associated with cycling accidents in a city in the south of Brazil: an observational study / Avaliação de traumatismos dentários associados a acidentes com bicicletas em uma cidade do sul do Brasil: um estudo observacional

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.

Dental trauma trends in emergency care:a comparative analysis before, during, and after COVID-19.

Objectives: This analysis details the characteristics of dental trauma in South Korea during the coronavirus disease 2019 (COVID-19) (DC) pandemic and compares them in patients before and after COVID-19 (BC and AC, respectively). Materials and Methods: Data were collected from medical records of patients who visited Seoul National University Bundang Hospital's Emergency Dental Care Center during three 12-month periods: BC, DC, and AC (BC from March 1, 2019 to February 29, 2020; DC from March 1, 2020 to February 28, 2021; AC from March 1, 2022 to February 28, 2023). A retrospective review was conducted to investigate patient age, sex, time of visit, cause, and diagnosis. The study included 1,544 patients: 660 BC, 374 DC, and 510 AC. Results: Significant difference in age and sex was not observed among the three periods; 1-9 years of age was the largest group (38.3% in BC, 29.6% in DC, and 27.8% in AC), and the percentage of male patients was greater than of female patients (male proportion as 63.5% in BC, 67.4% in DC, and 64.9% in AC). The number of patients generally peaked at a Saturday night in spring (for BC: May, Saturday, 18:00-19:59; for DC: March, Saturday, 18:00-19:59; for AC: April as the second most (October as the most peaked), Saturday, 20:00-21:59). The primary etiology of the dental trauma was identical in the three periods: falls, followed by sports. The most frequent diagnosis was laceration, followed by tooth avulsion and jaw fracture. Conclusion: Significant differences were not found between the characteristics and patterns of dental trauma in the BC, DC, and AC periods. However, due to the pandemic and social distancing, activities decreased and associated dental trauma-related incidents declined.
