RESUMEN

BACKGROUND: Dental trauma (DT) and falls have shown to be associated. On the other hand, postural balance is associated with falls and depends on the integration of the body's regulatory systems. The aim of this study was to investigate the potential relationship between DT and alteration of orthostatic balance in children. METHODS: This was a population-based case-control study involving 296 six-year-old schoolchildren. The case group included children with previous history of DT. The control group included children with no previous history of DT. Stabilometric measurements were the main exposure of this study. Logistic regression analyzes were performed to estimate potential differences in terms of chance of occurrence. RESULTS: The cases reviewed showed a 4.37 times chance of reduced balance in the measurement of the anteroposterior trajectory speed of the orthostatic center of pressure (COP), when children had their eyes closed. It also presented a chance of 3.06 times reduced balance in the measurement of the orthostatic center of pressure latero-lateral sway, with children with open eyes and stepping on a foam pad, and 4.00 times of reduced balance in the width of the latero-lateral sway of the orthostatic center of pressure, with children with open eyes and stepping on a foam pad. CONCLUSION: Children with previous history of DT showed a higher chance of experiencing a reduced orthostatic balance in different conditions when compared to children without the occurrence of trauma.

RESUMEN

BACKGROUND/OBJECTIVES: The use of different models for the fabrication of custom-fit mouthguards (MTGs) can affect their final thickness, adaptation, and shock-absorption properties. This study aimed to evaluate the adaptation, thickness, and shock absorption of ethylene-vinyl acetate (EVA) thermoplastic MTGs produced using conventional plaster or three-dimensional (3D) printed models. MATERIALS AND METHODS: A typical model with simulated soft gum tissue was used as the reference model to produce MTGs with the following two different protocols: plast-MTG using a conventional impression and plaster model (n = 10) and 3DPr-MTG using a digital scanning and 3D printed model (n = 10). A custom-fit MTG was fabricated using EVA sheets (Bioart) plasticized over different models. The MTG thickness (mm), internal adaptation (mm) to the typodontic model, and voids in the area (mm2) between the two EVA layers were measured using cone-beam computed tomography images and Mimics software (Materialize). The shock absorption of the MTG was measured using a strain-gauge test with a pendulum impact at 30° with a steel ball over the typodont model with and without MTGs. Data were analyzed using one-way analysis of variance with repeated measurements, followed by Tukey's post hoc tests. RESULTS: The 3DPr-MTG showed better adaptation than that of the Plast-MTG at the incisal/occlusal and lingual tooth surfaces (p < 0.001). The 3DPr-MTG showed a thickness similar to that of the Plast-MTG, irrespective of the measured location. MTGs produced using both model types significantly reduced the strain values during horizontal impact (3DPr-MTG 86.2% and Plast-MTG 87.0%) compared with the control group without MTG (p < 0.001). CONCLUSION: The MTGs showed the required standards regarding thickness, adaptation, and biomechanical performance, suggesting that the number and volume of voids had no significant impact on their functionality. Three-dimensional printed models are a viable alternative for MTG production, providing better adaptation than the Plast-MTG at the incisal/occlusal and lingual tooth surfaces and similar performance as the MTG produced with the conventional protocol.

RESUMEN

Immediate care and accurate diagnosis are essential for treating dental trauma. This report presents a 7-year-old boy suffered a bicycle accident with direct trauma to the mouth and extrusive luxation of teeth #11 and #21. The emergency treatment was performed within the first hour. Clinical examinations showed that both teeth exhibited 3 mm extrusion from comparing their incisal edges to their neighboring teeth, had edematous gingiva, showed grade 3 mobility and were painful to percussion. Radiographic exams showed incomplete root formation, widened periodontal spaces along their entire lengths and absence of bone or root fractures. The treatment consisted of immediate repositioning and semi-rigid splinting. After 15 days, tooth #11 exhibited no clinical signor symptom and tooth #21 was diagnosed with pulp necrosis, with an acute dentoalveolar abscess and intraoral edema. Immediate endodontic treatment was initiated (intracanal dressing with calcium hydroxide paste). At 30 days, another pulp sensibility test was performed on tooth #11, which had a negative response. In the same visit, the intracanal dressing of tooth #21 was replaced. The Ca(OH)2 medication was replaced every 6 months until the formation of an apical barrier. The final dressing consisted of gutta-percha and Grossman's sealer and was placed two and a half years after the first dressing appointment. The extrusive luxation resulted in two different sequelae: complete root obliteration in tooth #11 and anomalous root development after the formation of an apical barrier in tooth #21. The patient received orthodontic treatment after 6 years from the initial treatment with no negative outcome. After 18 years follow-up, both teeth were stabilized with no symptom or sign. It's important to follow the evolution of every trauma case continuously because the sequelae can be unpredictable.

RESUMEN

OBJECTIVE: To investigate the associations between family structure and social vulnerability with TDIs in children and adolescents. METHODS: An electronic search was conducted in seven databases (PubMed, Scopus, LILACS, Embase, Web of Science, ProQuest, and Google Scholar) to retrieve observational studies that evaluated the prevalence of TDIs. The risk of bias was assessed using the JBI Critical Appraisal Tools. Meta-analyses were also conducted using odds ratios (ORs) and 95% confidence intervals (CIs). The certainty of evidence was evaluated using the GRADE approach. RESULTS: Out of 7,424 records, seventeen articles were included (n = 18,806 children and adolescents aged between 0 and 19 years). Only two studies had a low risk of bias. Children and adolescents from nonnuclear families were more likely to suffer from TDIs (OR: 1.39; 95% CI: 1.17; 1.66). On the other hand, the level of social vulnerability did not show a positive association with TDIs (OR - 1.21; 95% CI: 1.00; 1.47). The GRADE approach assessed the certainty of evidence as low. CONCLUSION: Despite the uncertainty of the evidence, children and adolescents from nonnuclear families are more likely to have TDIs than are those from nuclear families. On the other hand, social vulnerability does not seem to be associated with episodes of TDIs in children and adolescents. CLINICAL RELEVANCE: Through knowledge of the risk factors for TDIs, it is possible to develop public policies for their prevention.

RESUMEN

El objetivo de este estudio fue determinar el conocimiento de profesores pertenecientes a establecimientos educacionales particulares subvencionados de Osorno con respecto al trauma dentoalveolar. Estudio de corte transversal, donde se realizó una encuesta presencial o en línea basada en un cuestionario con el fin de determinar el conocimiento sobre trauma dentoalveolar en profesores de enseñanza básica y media, pertenecientes a establecimientos educacionales de la comuna de Osorno, Chile. Los criterios de inclusión fueron, empleo a tiempo completo en el momento de la recolección de datos con al menos 1 año de experiencia docente. La jubilación, docentes con edad mayor o igual a 65 años y la falta de voluntad para participar en la encuesta, fueron considerados como criterios de exclusión. Para evaluar los resultados obtenidos se utilizó la prueba de la t de Student o ANOVA de una vía, con post hoc de Tukey. El nivel de significancia se fijó en p ≤ 0,05. Los profesores tuvieron un promedio de conocimiento sobre trauma dental de 5,0 ±3,0 puntos, de un puntaje máximo posible de 14, sin diferencias estadísticamente significativas entre el nivel de enseñanza donde ejerce la docencia (5,2±2,8, 4,9±3,3 y 4,9±3,3 puntos, p=0,88). El conocimiento sobre traumatismo dentoalveolar entre los profesores es deficiente. Se recomienda implementar programas educativos para el manejo de traumas dentales.


The aim of this study was to determine the knowledge of teachers affiliated to private subsidized schools in Osorno regarding dentoalveolar trauma. Cross-sectional study, where a survey was carried out face-to-face or online, based on a questionnaire to determine the knowledge about dentoalveolar trauma in elementary and middle school teachers, affiliated with educational establishments in the commune of Osorno, Chile. Inclusion criteria were full-time employment at the time of data collection, with at least one year of experience. Retirement, teachers aged 65 or older, and unwillingness to participate in the survey were considered exclusion criteria. The data were analyzed using the R software, Student's t test or one- way ANOVA, Tukey's post hoc. The significance level was set at p < 0.05. Teachers had an average knowledge of dental trauma of 5.0±3.0 points, out of a maximum possible score of 14, without statistically significant differences between the level of education where they teach (5.2±2.8, 4.9±3.3 and 4.9±3.3 points, p = 0.88). Knowledge regarding dentoalveolar traumatism among teachers of private subsidized schools in Osorno is deficient. It is recommended to implement educational programs for the management of dental trauma.

RESUMEN

BACKGROUND/AIM: The International Association of Dental Traumatology (IADT) is considered the foremost authority in Dental Traumatology. Fellowship status was introduced in 2015 and is considered an international standard of excellence. The Fellowship Committee of the IADT believed it was essential to survey members seeking information on the benefits of the IADT Fellowship and potential considerations for future development. This survey aimed to explore the perceptions of members of IADT surrounding the fellowship process in terms of interest, accessibility, equality, perceived prestige, and value to the membership. MATERIAL AND METHODS: The survey was sent to 546 IADT members, of whom 89 were fellows (as of 31 July 2022) from 74 countries via an email invitation. Answers were analysed using the Chi2 and Fisher's exact test (p < .05). RESULTS: The response rate to the survey was 20.69% (n = 113), including 28 fellows (24.78%). Forty-six respondents (40.71%) were female, and 67 (59.30%) were male. Dentists identified as specialists were significantly more likely to be involved in teaching dental trauma (p = .000008). A majority of respondents (87.76%; 86/98) expressed interest in obtaining fellowship, with increased interest from more recent graduates. Learning opportunities, obtaining expertise, networking and a sense of community and prestige, were key factors in considering fellowship. There was interest in alternate pathways other than examination alone, with 60.2% of 98 respondents suggesting a combination of publications /service to IADT/ reviewer for Dental Traumatology, 57.14% suggesting the submission of case reports, and 42.86% suggesting Honorary Fellowship. Respondents (73%) were willing to participate in online discussion forums and other professional development opportunities. This preference was more notable among non-fellows (75.29%) than fellows (67.85%). CONCLUSIONS: The survey indicates the diverse motivations and perceptions regarding the IADT Fellowship, despite the low participation of IADT members. Achieving fellowship status is desired by 87.7% of non-fellows. The majority of respondents were aware of the process, but main concerns were identified as eligibility criteria and examination difficulty. Options for alternate pathways and other initiatives promoting engagement were identified. Further exploration of these issues is required to be representative of the entire IADT membership. Addressing these obstacles could significantly enhance fellowship participation and overall member satisfaction within the IADT community.

RESUMEN

Dental traumas in sports are common and have physical, social, psychological, and economic impacts. The aim of this study was to determine, through a systematic review, the prevalence of dental trauma in contact and non-contact sports. This review was submitted to PROSPERO (CRD42023421206). Included studies addressed the prevalence of dental trauma in young athletes and adults above 18 years, excluding reviews, editorials, symposiums, or those evaluating athletes under 18 years. A literature search was conducted using the databases PubMed, Web of Science, Scopus, Embase, LIVIVO, SPORTDiscus, Dentistry & Oral Sciences Source (via EBSCO), and Lilacs and BBO, as well as gray literature. Bias risk was assessed using the Joanna Briggs Institute's Critical Appraisal Checklist. Data were synthesized considering study characteristics, population, sport, and outcomes. R Statistics software was used for all meta-analyses. A total of 1707 articles were identified. After applying eligibility criteria, eight were selected. Three studies, not previously observed, were later added after reading four systematic reviews on a similar topic. Fourteen contact sports and five non-contact sports were analyzed. The prevalence of dental trauma was 11.38% in contact sports and 5.24% in non-contact sports. Regardless of the type of sport, athletes face risks of dental trauma, with contact sports showing higher prevalence. The use of mouthguards is essential across all contact and non-contact sports as a preventive measure.

RESUMEN

AIM: The present retrospective cohort study aimed to evaluate luxated permanent teeth for pulp prognosis and risk factors. METHODOLOGY: Case records and radiographs of 224 patients, involving 427 luxated permanent teeth, referred for treatment at the Dental Trauma Center-School of Dentistry, Universidade Federal de Minas Gerais, (DTC-SD-UFMG) from 2014 to 2022, were assessed for pulp prognosis classified as vitality, necrosis and pulp canal obliteration (PCO). A competing risk survival analysis estimated the hazards of the three outcomes, and the effect of demographic, clinical and treatment variables was tested using a cause specific Cox regression model. RESULTS: Pulp vitality was found in163 teeth (38.2%), pulp necrosis in 120 teeth (28.1%) and 55 teeth (12.9%) developed PCO. Pulp vitality decreased in the presence of concomitant crown fractures (HR 0.38 95% CI [0.2-0.8] p = 0.006). The risk of pulp necrosis (HR 0.62 95% CI [0.4-0.96] p = 0.03) was lower in cases with open apices but increased with concomitant crown fractures (HR 4.0 95% CI [2.6-6.1] p = 0.001) and intrusions (HR 2.3 95% CI [1.2-4.1] p = 0.007). Lateral or extrusive luxations (HR 3.0 95% CI [1.3-6.9] p = 0.001) and open apices (HR 2.4 95% CI [1.2-4.7] p = 0.01) showed higher rates of PCO. CONCLUSION: Type of luxation, the diameter of the apical foramen, and the presence of concomitant crown fractures were main determinants of pulp prognosis after luxation injuries in permanent teeth. CLINICAL RELEVANCE: Pulp prognosis after tooth luxation is dependent on the presence and direction of tooth displacement together with infection control. CLINICAL TRIAL REGISTRATION: Not applicable.

RESUMEN

This systematic review evaluated preclinical studies to assess whether PBM has a more favorable histological response than other treatments used before delayed replantation of avulsed teeth. This review followed the PRISMA checklist and was registered in PROSPERO. MEDLINE (PubMed), Embase, Scopus and Web of Science were searched from their inception to July 14, 2022. Data were independently extracted by two reviewers. Data were collected about species, number of animals, number and type of teeth, groups evaluated, extra-alveolar time, parameters for PBM and other study groups, presence and characteristics of containment, observation time points, evaluation methods, characteristics evaluated, and significant results. The ARRIVE and SYRCLE tools were used to assess the methodological quality and risk of bias (RoB) of the studies. After screening, six studies were included in the review synthesis. Three of the four studies that evaluated root resorption as an outcome found that PBM decreases its occurrence after delayed tooth replantation. A meta-analysis was not conducted because some data were missing in the included studies. Half of the studies evaluating ankylosis found an increase in its occurrence after PBM. Two studies evaluated inflammatory responses and found a reduction of inflammation after PBM. In general, studies had high methodological heterogeneity, intermediate reporting quality and high RoB. Despite the methodological quality and RoB limitations of the studies, the histological responses after delayed tooth replantation were more favourable in the PBM groups. Preclinical studies supported by guidelines should define laser parameters for future clinical studies.

RESUMEN

RESUMEN Los traumatismos en la dentición primaria a menudo requieren un manejo diferente al que se hace en la dentición permanente. Se presenta el caso de una paciente mujer de 18 meses de edad, en aparente buen estado general, sin antecedentes médicos, que acude al servicio de Odontopediatría del Centro Dental Docente de la Universidad Peruana Cayetano Heredia a razón de que «se le ha incrustado un diente al caerse¼. Luego del examen extraoral, se observa un edema en el labio inferior; e intraoralmente se muestra un desplazamiento apical de la pieza 61. Radiográficamente, se observa que la pieza 61 se encuentra giroversada con desplazamiento apical. Diagnóstico: Luxación intrusiva de la pieza 61 y contusión del labio inferior. Tratamiento: Se realiza lavado con suero fisiológico; se le indica dieta blanda y que use cepillo de cerdas suaves; se mantiene en observación. Controles: Se realizó seguimiento durante siete meses, tiempo en el que se observó la reerupción espontánea del diente afectado. Por tanto, la reerupción espontánea es una opción de tratamiento en dientes primarios intruidos después de un traumatismo.


ABSTRACT Trauma in the primary dentition often requires different management than in the permanent dentition. We present the case of an 18-month-old female patient, in apparent good general condition, with no medical history, who came to the pediatric dentistry service of the Teaching Dental Center of the Universidad Peruana Cayetano Heredia because "a tooth had become incrusted when it fell out". After the extraoral examination, edema was observed in the lower lip and intraorally there was an apical displacement of tooth 61. Radiographically, it is observed that tooth 61 is rotated with apical displacement. Diagnosis: Intrusive dislocation of tooth 61 and contusion of the lower lip. Treatment: Washing with physiological saline solution, soft diet, and use of a soft bristle toothbrush; she was kept under observation. Controls: Follow-up was carried out for seven months, during which time spontaneous re-eruption of the affected tooth was observed. Therefore, spontaneous re-eruption is a treatment option in intruded primary teeth after trauma.


RESUMO Os traumatismos na dentição decídua requerem frequentemente um tratamento diferente do que na dentição permanente. Apresentamos o caso de uma paciente do sexo feminino, com 18 meses de idade, em aparente bom estado geral, sem antecedentes médicos, que compareceu ao serviço de odontopediatria do Centro Dental Docente da Universidad Peruana Cayetano Heredia porque "um dente tinha ficado incrustado ao cair". Após o exame extraoral, observou-se edema no lábio inferior e, intraoralmente, um deslocamento apical do dente 61. Radiograficamente, verificou-se que o dente 61 estava rodado com deslocamento apical. Diagnóstico: Deslocamento intrusivo do dente 61 e contusão do lábio inferior. Tratamento: lavagem com soro fisiológico, dieta branda e uso de escova de dente de cerdas macias; o paciente foi mantido em observação. Controlos: O acompanhamento foi realizado durante sete meses, período durante o qual se observou a reerupção espontânea do dente afetado. Portanto, a reerupção espontânea é uma opção de tratamento em dentes decíduos instruídos após trauma.

RESUMEN

BACKGROUND/AIMS: The recommended treatment for uncomplicated crown fractures is bonding the fractured fragment or the fragment reattachment. A paucity was identified regarding the studies comparing the efficacy of micro-hybrid and nanohybrid composites in fragment reattachment. Hence, the present study aimed to evaluate and compare three materials for bonding of fragments rehydrated by humidification in teeth with uncomplicated crown fractures. MATERIAL AND METHODS: Eighty mandibular bovine incisors with similar dimensions and free of any structural deformities were fractured similar to the technique followed in previous studies. Fracture was simulated, fragments, and stumps were coded, stumps were stored in artificial saliva and the fragments were dehydrated at room temperature and pressure. They were randomly assigned to Group-1 (no rehydration), Group-2 (rehydrated and bonded by flowable nanohybrid composite-3M Filtek Supreme Syringe Flowable Composite Resin-A2, Sao Paulo, Brazil), Group-3 (rehydrated and bonded by flowable micro-hybrid composite- Ruby Flow, InciDental, England, United Kingdom), and Group-4 (rehydrated and bonded by light-cured Glass-Ionomer-Cement-Voco Ionoseal, Cuxhaven, Germany). The samples were subjected to a universal testing machine to evaluate the force required to fracture the bonded fragments. RESULTS: The highest median value of the force required to fracture was recorded for Group 2 (208.4 N) followed by Group 3 (195.2). The force required to fracture the bonded fragments was lowest in Group 4 (67.2 N) which was lower than the negative control (131.4 N). The differences between the observations in Groups 2 and 3 were not found to be statistically significant. CONCLUSION: The nano and micro-hybrid composites showed greater force required to fracture than fragments bonded by LC-GIC. Dehydrated fragments bonded using nanocomposites performed better than rehydrated fragments bonded by using LC-GIC.

RESUMEN

Aging may increase the risk of maxillofacial and dentoalveolar trauma (MDT). This review assessed global trends in scientific publications on MDT in the elderly. Six databases were searched. Studies about MDT in the elderly (≥60 years old) were included in two text mining stages (S1 and S2). In S1, all studies with elderly subjects were included, while in S2 only studies in which the elderly were assessed in a separate set of data or in a subanalysis by age groups were included. In S1, relevant data were mined using VantagePoint™ software. In S2, data were descriptively analyzed. There were 2265 studies at S1 and 110 at S2. The publication dates spanned from 1963 to 2023. In S1, the most cited keywords and terms were aged (n = 1872), male (n = 1839), female (n = 1777), "mandible fracture" (n = 460), "orbit fracture" (n = 362), and "maxilla fracture" (n = 118). Thirty authors published 10 or more articles with visible collaboration networks. There was a progressive increase in publications, especially in Europe (n = 150). In S2, most studies were case reports/case series (n = 62). The primary etiology was accidental falls (n = 84), the most affected region was the middle third of the face (n = 65), and dental trauma was rarely reported (n = 15). Cone Beam computed tomography was the most used diagnostic tool (n = 67). Of the 81 articles that addressed therapy, 52 opted for surgical treatment. Although there has been an increase in the number of articles on MDT over the years, studies with the elderly population as a specific study group are still needed. Accidental falls were the most reported etiology, while the middle third of the face and the mandible were the anatomic region and bone most affected, respectively. The high number of case reports indicates the need for improvement in the available scientific evidence about MDT in the elderly.

RESUMEN

Abstract The objective of this study is to determine the impact of oral conditions on the quality of life related to the oral health of preschool children in a rural and urban area of Cusco. The study was descriptive and cross-sectional, from a population of 179 preschoolers aged 3 to 5 years, from two public early childhood education institutions, and their respective parents or caregivers in the department of Cusco, Peru. We worked with the entire population that met the inclusion and exclusion criteria, seventy-four preschool children were selected for each area, deciding to have the same amount of children per group based on the smallest group. A clinical odonto-stomatological examination was carried out for oral conditions (dental caries, malocclusion, and dental trauma) according to the WHO's criteria and a survey that was used for sociodemographic characteristics. In addition, a validated Peruvian version of the ECOHIS questionnaire was used to obtain data on the impact on quality of life. All the variables of the total and individual scores of the ECOHIS domains were analyzed individually and the Kruskal-Wallis test was used to determine the association between variables. The oral conditions prevalence in preschool children in rural areas referring to dental caries was 100% (dmft index > 6), dental trauma 10.8%, and malocclusions 60.8%; for the urban area dental caries was 93.2% (dmft index > 6), dental trauma 9.5% and malocclusions 36.5%. Of the three oral conditions only the experience of dental caries was related to the OHRQOL of preschoolers in urban and rural areas.


Resumen El objetivo de este estudio es determinar el impacto de las alteraciones bucales en la calidad de vida relacionada con la salud bucal de niños preescolares de una zona rural y urbana de Cusco. El estudio fue descriptivo y transversal, de una población de 179 preescolares de 3 a 5 años de edad, de dos instituciones públicas de educación inicial, y sus respectivos padres o cuidadores en el departamento de Cusco, Perú. Se trabajó con toda la población que cumplió con los criterios de inclusión y exclusión, se seleccionaron setenta y cuatro niños preescolares por cada área, decidiendo tener la misma cantidad de niños por grupo en base al grupo más pequeño. Se realizó un examen clínico odonto-estomatológico para detectar alteraciones bucales (caries dental, maloclusión y trauma dental) según los criterios de la OMS y una encuesta que se utilizó para las características sociodemográficas. Además, se utilizó una versión peruana validada del cuestionario ECOHIS para obtener datos sobre el impacto en la calidad de vida. Todas las variables de los puntajes totales e individuales de los dominios ECOHIS fueron analizadas individualmente y se utilizó la prueba de Kruskal-Wallis para determinar la asociación entre variables. La prevalencia de alteraciones bucales en niños preescolares de zonas rurales referida a caries dental fue del 100% (índice dmft > 6), traumatismo dental 10,8% y maloclusiones 60,8%; para la zona urbana la caries dental fue del 93,2% (índice dmft > 6), el traumatismo dental 9,5% y las maloclusiones 36,5%. De las tres alteraciones bucales, sólo la experiencia de caries dental se relacionó con la OHRQOL de los preescolares de las zonas urbana y rural.

RESUMEN

Las armas de aire comprimido son utilizadas desde hace muchos años con distintos usos que van desde el tiro recreativo hasta el control de plagas. Las más comunes son aquellas que disparan ''balines" o esferas metálicas que pueden llegar a tener capacidad de penetrar tejidos dependiendo del tipo de carga y de la longitud del cañón. Se presenta un caso clínico de un masculino que fue agredido con un arma tipo pistola con carga de CO2 que recibió un impacto a nivel facial y sufrió laceración en piel de labio y fractura dental complicada.


Air guns have been used for many years for a variety of purposes ranging from recreational shooting to pest control. The most common are those that shoot "pellets" or metallic spheres that can penetrate tissues depending on the type of load and the length of the barrel. A clinical case is presented of a male who was assaulted with a CO2-loaded pistol-type weapon, hit at facial level, and suffered laceration of the lip's skin and complicated dental fracture.

RESUMEN

BACKGROUND/AIM: The interaction between the ethylene-vinyl acetate (EVA) with distinct materials utilized for obtaining dental models can affect the performance of resulting mouthguards. This study attempted to evaluate the effect of different materials for conventional (dental stone) or 3D-printed (resin) models on EVA's physical and mechanical properties and surface characteristics. MATERIAL AND METHODS: EVA sheets (Bioart) were laminated over four model types: GIV, conventional Type IV dental stone model (Zhermak); ReG, resin-reinforced Type IV dental stone model (Zero Stone); 3DnT, 3D resin printed model (Anycubic) without surface treatment; 3DT, 3D-printed model (Anycubic) with water-soluble gel (KY Jelly Lubricant, Johnson & Johnson) coating during post-curing process. The EVA specimens were cut following the ISO 37-II standard (n = 30). Shore A hardness was measured before and after plasticization on the contact (internal) or opposite (external) surfaces with the model. The breaking force (F, N), elongation (EL, mm), and ultimate tensile strength (UTS, MPa) were measured using a universal testing machine. Macro-photography and scanning electron microscopy were adopted for classifying the EVA surface alteration. Data were analyzed by one-way ANOVA with repeated measures, followed by Tukey's test (α = .05). RESULTS: Plasticization significantly decreased Shore A values for the tested EVA regardless of the model type (p < .001). Higher F, El, and UTS values were verified for the EVA with 3DT and GIV models compared to ReG and 3DnT (p < .001). 3DnT models resulted in severe surface alteration and a greater reduction of the mechanical properties of the EVA. CONCLUSION: The interaction of EVA with 3D resin-printed models without surface treatment or resin-reinforced Type IV dental stone models significantly affected the physical and mechanical properties of this material. The utilization of water-soluble gel coating during the post-curing process of 3D resin printed models improved the mechanical properties of the EVA, similarly when this material was plasticized over conventional Type IV dental stone model.

RESUMEN

RESUMEN Objetivo: Describir las lesiones en tejidos dentarios y trastornos de la salud bucal encontradas durante el examen médico ocupacional en trabajadores del sector construcción de Lima, Perú. Material y métodos: Estudio epidemiológico transversal realizado en 150 trabajadores del sector construcción, seleccionados mediante muestreo aleatorio simple. Se realizó una evaluación estomatológica mediante observación directa y se empleó un instrumento de evaluación odontológico-ocupacional con índices para caries dental, severidad de caries y traumatismos dentales e indicadores de consecuencias clínicas de caries no tratada (patología pulpar) y lesiones no cariosas. Resultados: La experiencia de caries de los operadores sin estudio superior (CPOD = 14,99) y con estudio superior (CPOD = 13,06) fue superior frente a los supervisores (CPOD = 8,23) y administrativos (CPOD = 5,08). Los trabajadores operadores sin estudio superior (SiC = 18,04) y con estudio superior (SiC = 17,17) presentaron peores indicadores de significancia de caries frente a los supervisores (SiC = 13,67) y administrativos (SiC = 8,25). Además, los operadores sin estudio superior presentaron mayor carga de consecuencias clínicas de caries no tratada (PUFA = 2,35; severidad = 9,2%) en comparación con los operativos con estudio superior (PUFA = 1,91; severidad = 8,4%), los supervisores (PUFA = 0,53; severidad = 2,1%) y los administrativos (PUFA = 0,46; severidad = 1,8%), así como mayor frecuencia de lesiones no cariosas (47,3 %) y traumatismos dentales (21,3 %). Conclusiones: La salud dental, sus consecuencias clínicas y la estructura de los tejidos dentarios de los trabajadores operativos de una empresa constructora se encuentran más afectadas en comparación con los otros grupos laborales de la misma empresa.


ABSTRACT Objective: To describe the lesions in dental tissues and oral health disorders found during the occupational medical examination of workers in the construction sector in Lima, Peru. Material and methods: A cross-sectional epidemiological study was carried out on 150 workers in the construction sector, selected by simple random sampling. A stomatological evaluation was carried out by direct observation, and a dental-occupational evaluation instrument was used with indexes for dental caries, caries severity and dental trauma, and indicators of clinical consequences of untreated caries (pulp pathology) and non-carious lesions. Results: The caries experience of operators without higher education (CPOD = 14.99) and with higher education (CPOD = 13.06) was higher than that of supervisors (CPOD = 8.23) and administrative workers (CPOD = 5.08). The operators without higher education (SiC = 18.04) and with higher education (SiC = 17.17) presented worse caries significance indicators compared to supervisors (SiC = 13.67) and administrative workers (SiC = 8.25). In addition, operators without higher education had a higher burden of clinical consequences of untreated caries (PUFA = 2.35; severity = 9.2%) compared to operators with higher education (PUFA = 1.91; severity = 8.4%), supervisors (PUFA = 0.53; severity = 2.1%) and administrators (PUFA = 0.46; severity = 1.8%), as well as a higher frequency of non-carious lesions (47.3%) and dental trauma (21.3%). Conclusions: Dental health, its clinical consequences, and the structure of the dental tissues of the operative workers of a construction company are more affected compared to the other labor groups of the same company.

RESUMEN

BACKGROUND/AIM: Evaluate the informative content in tooth avulsion videos intended for dentists available on YouTube™ and analyse their compliance with the International Association of Dental Traumatology (IADT) guidelines 2020. MATERIALS AND METHODS: Google Trends was used to identify the most searched term for tooth avulsion. Tooth avulsion-related videos in Brazilian Portuguese intended for dentists were searched on YouTube™ with a 12-month filter. Two raters reviewed these videos to extract their features and evaluate and qualify them with two 9-point checklists based on the IADT 2020 guidelines. The emergency steps for tooth avulsion at the accident site were assessed before, during and after clinical management; each step received 1 point if present and 0 points if absent. The final score ranged from 0 to 9 points on each checklist (18 points total), and the total score was used to classify the videos as having poor, moderate or rich content. Reliability and video quality were evaluated by an adapted version of the DISCERN tool and global quality scale (GQS), respectively. The data were analysed with the Mann-Whitney U-test, Pearson chi-square test, and the Kappa statistic (p < .05). RESULTS: Of 60 videos, 8 were included. All were uploaded by dental professionals or undergraduate students; the average duration was 11 min (range: 0.40-65 min), and the average number of views was 56.75. Half the videos (50%) had maximum completeness scores for questions about emergency dentist referral before clinical management, and more than half (75%) had maximum completeness regarding the steps required during and after treatment. Rich videos had higher GQS scores (p = .049) without significant correlation. CONCLUSIONS: Although most videos in Brazilian Portuguese were considered high-quality according to the IADT checklist, half of them presented partial absence of information regarding orientations at the accident site.

RESUMEN

Introdução: O traumatismo dentário é uma ocorrência frequente durante a infância e adolescência. Geralmente, o diagnóstico acontece de forma tardia, devido à falta de conhecimento da população. Cada tipo de trauma necessita de uma conduta única e especializada. Nos casos de comprometimento pulpar, é necessário cuidado quanto à escolha da técnica a ser empregada, bem como a seleção da medicação intracanal que, por sua vez, apresenta grande interferência no sucesso do tratamento. Não obstante o avanço das técnicas de instrumentação, a troca da medicação entre as sessões nesses casos é mandatória. Relato de caso: Um paciente, sexo masculino, em idade escolar (15 anos) apresentou-se ao serviço de saúde bucal com relato de escurecimento e dores na mastigação após trauma dentário durante a infância. Os testes de vitalidade pulpar revelaram necrose pulpar, com resultado negativo no teste térmico e positivo na percussão. O exame radiológico evidenciou uma lesão apical, juntamente com reabsorção externa no elemento 21, confirmado em tomografia. O paciente foi submetido a um tratamento endodôntico. Resultado: Após o tratamento, foi solicitado novo exame tomográfico, em que se evidenciou um processo de cicatrização óssea no periápice e reabsorção por substituição na lesão cervical. Conclusão: A partir deste caso clínico, pôde-se evidenciar a importância do diagnóstico adequado, do manejo e da técnica endodôntica eficaz na resolução de problemas decorrentes de traumas dentários em pacientes jovens.


Introduction: Dental trauma is a frequent occurrence during childhood and adolescence. Generally, diagnosis happens late, due to lack of knowledge among the population. Each type of trauma requires a unique and specialized approach. In cases of pulp involvement, care must be taken when choosing the technique to be used, as well as the selection of intracanal medication, which, in turn, has a major impact on the success of the treatment. Despite advances in instrumentation techniques, changing medication between sessions in these cases is mandatory. Case report: A male patient of school age (15 years old) presented to the oral health service with reports of darkening and pain when chewing following dental trauma during childhood. Pulp vitality tests revealed pulp necrosis, with a negative result in the thermal test and positive in percussion. The radiological examination showed an apical lesion, together with external resorption in element 21, confirmed on tomography. The patient underwent endodontic treatment. Result: After treatment, a new tomographic examination was requested, which showed a process of bone healing in the periapex and resorption by replacement in the cervical lesion. Conclusion: From this clinical case, it was possible to highlight the importance of adequate diagnosis, management, and effective endodontic technique in solving problems arising from dental trauma in young patients.

RESUMEN

BACKGROUND/AIM: Removing resin composites used for bonding dental trauma splints may result in irreversible damage to the enamel. This in vitro study evaluated the influence of additional violet illumination and different bur types on damage caused to tooth enamel. MATERIALS AND METHODS: Fifteen maxillary models with four bovine incisor teeth were prepared. All models were scanned using a laboratory scanning system (s600 ARTI; Zirkonzahn). Six experimental groups (n = 10) were generated by two study factors: lighting type (three levels), (1) low-cost (5-7 US$) violet LED flashlight (LUATEK, LT 408); (2) VALO Cordless light curing unit (Ultradent) with black lens; or (3) without additional illumination; and rotatory instrument (two levels), (1) diamond bur or (2) multifluted tungsten-carbide bur. New scanning was performed after splint removal, and the generated files were superimposed on the initial scans using Cumulus software. The light emitted by both violet light sources was characterized by using integrating sphere and beam profile. A qualitative and quantitative analysis of enamel damage and two-way ANOVA followed by Tukey's post hoc was used at an α = 0.05. RESULTS: The use of low-cost violet flashlight that emitted the violet peak light at 385 nm and VALO Cordless with black lens at 396 nm resulted in significantly lower damage to the enamel surface than those in the groups without additional violet light (p < .001). An interaction between rotatory instruments and lighting was found. When no additional violet lighting was used, the diamond bur presented higher mean and maximum depth values. CONCLUSIONS: Fluorescence lighting facilitated the removal of remnant resin composite dental trauma splints, leading to less invasive treatment. The diamond bur resulted in higher enamel damage than that affected by the multifluted bur when no violet lighting was used. A low-cost violet flashlight is a useful fluorescence-aided identification technique for removing resin composite dental trauma splints.

RESUMEN

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.
