ABSTRACT

Objetivo: Presentar la terapia regenerativa como una al- ternativa para la resolución de un caso de traumatismo denta- rio en un diente permanente incompletamente desarrollado. Caso clínico: Se realizó el tratamiento de un incisivo central superior con mortificación pulpar y periodontitis api- cal aguda subsecuente a trauma dental en un paciente de 8 años de edad. Se aplicó el protocolo de regeneración pulpar recomendado por la Asociación Americana de Endodoncia. Se estimuló la formación de un coágulo en el interior del con- ducto a partir de los tejidos periapicales, previa desinfección con la pasta triple antibiótica, y finalmente se colocó mineral trióxido agregado coronal a este. Se obtuvo así una matriz es- teril que permitió el crecimiento de nuevo tejido y se realiza- ron controles periódicos durante 4 años. Se constató silencio clínico. Radiográficamente, se observó la formación de tejido sobre las paredes del conducto y el cierre apical. Conclusión: La terapia regenerativa como alternativa de tratamiento, en este caso, permitió la disminución de la luz del conducto por el depósito de tejidos calcificados y el cierre del foramen apical, mejorando el pronóstico de la pieza dentaria (AU)


Aim: To present pulp regeneration therapy as an alter- native to resolve dental trauma in immature permanent teeth. Clinical case: We report a clinical case of an immature central superior incisor with pulp mortification and acute api- cal periodontitis subsequent to dental trauma, in an 8 year old patient. The pulp Regeneration protocol recommended by the American Endodontics Association was applied. We stimulated a clot formation inside the duct from periapical tissues and after disinfection with a mixture of three antibi- otics mineral trioxide aggregated was finally place coronal to the clot. Thus a sterile matrix was obtained that allowed new tissue's growth. Periodic check-up visits were carried out over a 4 years period. Clinical silence was observed. Tissue formation on duct walls and apical closure were radiograph- ically detected (AU) Conclusion: Regenerative therapy is an alternative for the treatment of immature permanent teeth, in ths clinical case it allowed the reduction of the width of the duct by the opposition of hard tissues and the closure of the apical fora- men improving the forecast of these teeth.

ABSTRACT

Abstract Objective: To evaluate the factors associated with the occurrence of dental trauma in children up to six years of age and describe the results of clinical follow-up and possible sequelae. Material and Methods: A retrospective study was carried out with data collected from the dental records of 96 pediatric patients up to 6 years old with traumatized primary teeth who sought care from the. Pediatric Dental Trauma project of a private university in the city of Rio de Janeiro from July 2014 to July 2017, and who had clinical and radiographic follow-up for up to three months as of their initial visit. Results: 96 children (58.3% boys and 41.7% girls) included who presented 166 traumatized primary teeth. Intrusion was the most observed type of trauma and in 45.8% of cases, the care occurred one-week post trauma. The maxillary central incisors were the most affected teeth (97.6%). The prognosis of the dental elements with more than 3 months of follow-up was considered favorable, and 59.6% of the teeth did not present any clinical or radiological sequelae. Oral hygiene instruction and monitoring were the most common approaches. Conclusion: The prevalence of dental trauma in the present study was high and occurred mainly in domestic settings. The upper central incisors were the teeth that suffered the most injuries. The presence of patients at follow-up visits was an important factor for the positive result in most cases.

ABSTRACT

Objetivo: Informar el tratamiento de dos piezas con fractura radicular horizontal del tercio medio, patrones de curación y seguimiento por cinco años. Caso clínico: Se presentó a la consulta una niña de 9 años de edad con traumatismo de 10 días de evolución. Examen clínico: fractura amelodentinaria restaurada en la pieza 2.2, movilidad y sensibilidad a la percusión y palpación en ambos incisivos centrales superiores. Examen radiográfico: fractura radicular horizontal de tercio medio en piezas 1.1 y 2.1. Tratamiento: inmovilización con placa removible durante 4 semanas, indicaciones de higiene y uso, y controles de seguimiento. Al primero y al cuarto mes, ambos incisivos mostraron ausencia de movilidad, reacción positiva de sensibilidad y signos radiográficos de reabsorción superficial interna y externa. A los 6 meses, el 1.1 evidenció signos de reparación con tejido conectivo, y el 2.1, signos clínicos y radiográficos de necrosis pulpar del fragmento coronario. Se realizó el tratamiento endodóntico de la pieza 2.1 hasta el nivel de la fractura con pasta a base de hidróxido de calcio, y luego de la comprobación de la formación de una barrera de tejido duro, se obturó definitivamente con gutapercha y sellador endodóntico. Cinco años después del traumatismo, ambos incisivos se mostraron asintomáticos y los estudios por imágenes evidenciaron una completa consolidación de las fracturas. Conclusión: Un diagnóstico temprano, procedimientos apropiados de tratamiento, el conocimiento de los procesos curativos y un monitoreo cuidadoso de todos los parámetros clínicos y radiográficos son claves para un enfoque correcto y conservador de las piezas dentarias con fractura radicular (AU)


Aim: To report the treatment, healing patterns and fiveyear follow-up of two permanent incisors with horizontal root fracture located in the middle third. Case report: A 9-year-old girl who came to our consultation 10 days after a dental trauma. Clinical examination: restored enamel-dentin fracture in upper left lateral incisor; mobility and sensitivity to percussion and palpation in both upper central incisors. Radiographic examination: horizontal root fracture in the middle third of both upper central incisors. Treatment: stabilization with a removable splint for 4 weeks, indications for hygiene, use of the splint and follow-up controls. At first and fourth month, central incisors presented absence of mobility, positive response to pulp testing and radiographic signs of internal and external superficial resorption. At sixth month, signs of healing with connective tissue were found on the right central incisor, while the left one showed clinical and radiographic signs of necrosis of the coronal fragment. The root canal of this segment was treated initially with a calcium hydroxide paste and, after verifying the formation of a hard tissue barrier, it was filled with gutta- percha and endodontic sealer. Five years after the trauma, both central incisors were asymptomatic and imaging studies showed complete healing of the fractures. Conclusion: Early diagnosis, appropriate treatment procedures, knowledge of healing patterns and careful monitoring of clinical and radiographic parameters are key factors for a proper and conservative approach of injured tooth with root fracture (AU)

ABSTRACT

ABSTRACT: Dento-alveolar traumas are one of the most frequent injuries to teeth, mainly affecting the upper incisors due to their exposed position in the dental arch. In such cases, esthetics, function and phonetics of anterior teeth may be compromised. Furthermore, when there is involvement of the biological width, there is often a poor prognosis. This case report describes the multidisciplinary approach to tooth fragment re-attachment in a fracture with biological width violation. The patient presented with an oblique crown fracture in the maxillary right lateral incisor, extending from the buccal to palatal side, as well as a biological width invasion. The re-establishment of the biological width was obtained by periodontal surgery to achieve clinical-crown lengthening and tooth fragment re-attachment with a glass fiber post to increase retention. After 3 years of follow-up, the rehabilitated lateral incisor remains in good condition, with satisfactory esthetic and periodontal health.

ABSTRACT

Abstract Objective To compare periapical radiograph (PR) and cone-beam computed tomography (CBCT) in the diagnosis of alveolar and root fractures. Material and Methods Sixty incisor teeth (20 higid and 40 with root fracture) from dogs were inserted in 60 anterior alveolar sockets (40 higid and 20 with alveolar fracture) of 15 macerated canine maxillae. Each fractured socket had a root fractured tooth inserted in it. Afterwards, each maxilla was submitted to PR in two different vertical angulation incidences, and to CBCT imaging with a small field of view (FOV) and high-definition protocol. Images were randomized and posteriorly analyzed by two oral and maxillofacial radiologists two times, with a two-week interval between observations. Results Sensitivity and specificity values were good for root fractures for PR and CBCT. For alveolar fractures, sensitivity ranged from 0.10 to 0.90 for PR and from 0.50 to 0.65 for CBCT. Specificity for alveolar fractures showed lower results than for root fractures for PR and CBCT. Areas under the ROC curve showed good results for both PR and CBCT for root fractures. However, results were fair for both PR and CBCT for alveolar fractures. When submitted to repeated measures ANOVA tests, there was a statistically significant difference between PR and CBCT for root fractures. Root fracture intraobserver agreement ranged from 0.90 to 0.93, and alveolar fracture intraobserver agreement ranged from 0.30 to 0.57. Interobserver agreement results were substantial for root fractures and poor/fair for alveolar fractures (0.11 for PR and 0.30 for CBCT). Conclusion Periapical radiograph with two different vertical angulations may be considered an accurate method to detect root fractures. However, PR showed poorer results than CBCT for the diagnosis of alveolar fractures. When no fractures are diagnosed in PR and the patient describes pain symptoms, the subsequent exam of choice is CBCT.

ABSTRACT

To present an uncommon disturbance of root development with ingrowth of bone and periodontal tissue into the pulp space in a delayed replanted immature permanent incisor at five years of follow-up. Severe arrest of root formation with uncommon healing of an immature permanent maxillary incisor after delayed replantation is reported. Continued development of a tooth root separate from the body of the tooth was not observed. A 6-year-old girl sustained an avulsion injury to her upper left central permanent incisor. The tooth was replanted and splinted 2 hours after the accident. Patient has been monitored clinically and with radiography for 5 years. The periodontal tissues presented good healing without replacement resorption. However, severe arrest of root formation with development of hard-like tissue and internal periodontal ligament inside the pulp canal have been observed. Despite being a delayed tooth replantation, the patient has been asymptomatic, and has maintained alveolar bone volume. Clinicians must be vigilant and monitor traumatized immature teeth closely.


El objetivo de este trabajo fue presentar una alteración poco frecuente del desarrollo de la raíz con el crecimiento del tejido óseo y periodontal en el espacio pulpar en un incisivo permanente inmaduro reimplantado de manera tardía, a los cinco años de seguimiento.Se observó una suspensión severa de la formación de raíces con cicatrización poco común, de un incisivo maxilar permanente inmaduro después de una reimplantación tardía. No se observó el desarrollo continuo de la raíz dentaria separada del diente. Una niña de 6 años de edad sufrió una lesión por avulsión en su incisivo central superior izquierdo. El diente fue replantado dos horas después del accidente. La paciente ha sido monitoreada clínicamente y con exámenes radiológicos durante 5 años. Los tejidos periodontales presentaron buena cicatrización sin reabsorción de reemplazo. Sin embargo, se ha observado una detención severa de la formación de las raíces, con desarrollo de tejido duro y ligamento periodontal interno dentro del canal pulpar. A pesar de ser una reimplantación tardía del diente, la paciente presenta asintomática, y ha mantenido el volumen del hueso alveolar. Los médicos deben estar atentos y mantener en observación los dientes inmaduros traumatizados.

ABSTRACT

Objetivo: informar el tratamiento de un diente avulsionado con reabsorción radicular y obturado únicamente con compuesto de mineral trióxido (MTA, Angelus, Londrina, Brasil). Caso clínico: en un paciente de 17 años que presentó avulsión del 11, con tiemop extraoral mayor a 60 minutos, 6 meses después se observó reabsorción radicular externa inflamatoria comunicante con ligamento periodontal, pérdida de cresta ósea, tracto sinuoso y movilidad dental. A pesar de no haber buen pronóstico, se realizó el tratamiento de la reabsorción con medicación con hidróxido de calcio y obturación única del conducto con MTA. Se efectuó un control con tomografía de cono a los 2 años y 10 meses, el cual mostró la no continuación de la reabsorción de cresta ósea. Conclusión: el tratamiento adecuado y la obturación con MTA ofrecen la oportunidad de lograr una buena cicatrización de los tejidos perirradiculares y preservar dientes comprometidos.

ABSTRACT

Los traumatismos dentarios constituyen uno de los motivos más frecuentes en la consulta odontopediátrica. Si bien las fracturas radiculares en dentición primaria son las lesiones traumáticas menos prevalentes (2-4 por ciento), son de difícil resolución y ocasionan la pérdida de dichas piezas en la mayoría de los casos. Objetivo: describir la resolución del traumatismo con fractura radicular en ambos incisivos centrales superiores primarios. Diagnóstico de la situación inicial: paciente masculino de 4 años que acude con su madre a la Cátedra de Odontología Integral Niños de la FOUBA presentando un traumatismo dental de 2 horas de evolución. Diagnóstico clínico-radiográfico: fractura radicular horizontal de tercio medio del 5.1 y 6.1 (sin reabsorción fisiológica radicular), sin desplazamiento del fragmento coronario, con laceración de labio superior y encía marginal. Secuencia de procedimientos operatorios: historia clínica con consentimiento informado; anamnesis médica y odontológica; examen clínico y radiográfico de 5.1 y 6.1 y antagonistas; limpieza de tejidos blandos con clorhexidina; impresión con alginato; confección de placa posicionadora para ferulización; prueba e instalación de la placa; indicaciones al paciente y a su madre: uso permanente durante 45 días y uso nocturno, para comer y hacer deportes 45 días más. Recomendaciones de higiene; controles inmediatos: 30 y 45 días y 3 y 6 meses. Resolución del caso: en todos los controles, ambas piezas se presentaron asintomáticas. A los 6 meses se observa la correcta cicatrización radicular y la presencia de vitalidad en ambos incisivos. Conclusiones: el tratamiento temprano y los controles posteriores son fundamentales para preservar la salud pulpar y conseguir la reparación de los tejidos duros afectados.

ABSTRACT

Horizontal root fractures are a type of traumatic dental injury. Horizontal root fractures are classified as apical third, middle third, and cervical third of the root based on the fracture line and on the degree of dislocation of the coronal fragment. The prognosis of the tooth depends on the patient’s age, stage of root growth, mobility of the coronal fragment and diastasis of the fragments. Proper clinical and radiographic examination should be done to reveal apical root fractures. Hence, the treatment plan can be decided depending on the type of fracture and extent of fracture line. This review was conducted to evaluate the apical third horizontal root fractures in order to determine the appropriate therapy.

ABSTRACT

Restoration of a traumatically injured tooth presents a clinical challenge for a predictable aesthetic outcome. This case report describes a multidisciplinary approach of a subgingivally fractured permanent maxillary central incisor. A removable orthodontic appliance was used for orthodontic extrusion of root, and surgical gingival recontouring was done with electrocautery to reestablish the biological width. Form and function were restored establishing biological width and esthetics was repaired with porcelain fused to metal crown.

ABSTRACT

La reimplantación dentaria ha sido uno de los procedimientos más exigente de rigor y precisión en cuanto a las condiciones que deben existir para lograr el éxito esperado. El propósito de esta presentaciòn es mostrar la evolución y tratamiento del auto-implante del incisivo lateral superior izquierdo, 72 horas después de avulsionado. Se trata de paciente masculino de 18 años de edad, con antecedentes de salud. Acude a consulta luego de tres días de avulsionado el incisivo lateral superior izquierdo por trauma. Se le explicó al paciente el posible fracaso del tratamiento por el tiempo transcurrido, puesto que la inmediatez con que sea tratado favorece el éxito. Se le realizó el reimplante dentario y ferulizó. Se realizó el tratamiento endodóntico al diente en dos sesiones de una semana entre ellas. Se realizaron evoluciones trimestrales y luego semestrales. Casi cinco años después, la evidencia radiográfica no muestra complicaciones existentes y clínicamente presenta una apariencia normal. Los resultados obtenidos fueron satisfactorios y después de cinco años el paciente se mantiene con su diente en boca completamente asintomático(AU)


The dental re-implantation is one of the procedures demanding most rigor and precision in terms of the conditions required to achieve the expected success. Our purpose is to present the evolution and treatment of a case of auto-implantation of the upper left lateral incisor 72 hours after avulsion. The patient was a male 18 year-old with a history of ill health presents three days after avulsion of the upper left lateral incisor as a result of trauma. The patient was informed of the possible failure of the treatment due to the time elapsed. In cases such as this one, immediate treatment is essential to achieve success. Dental re-implantation and ferulization were performed. The tooth was treated endodontically on two visits one week apart. Checkups were conducted which were quarterly at first and then biannual. Almost five years later, radiographic evidence shows no complications and clinical appearance is normal. The results were satisfactory. The patient has preserved his tooth for five years and his status is totally asymptomatic(AU)

ABSTRACT

The aim of this study was to determine the prevalence of sequelae in permanent teeth that had their predecessors traumatized and investigate associated factors. The study was carried out with clinical and radiographic data from 137 patient charts of the Traumatized Patient Care Program, Federal University of Santa Catarina (Brazil), totalizing 253 teeth. Data were gathered on gender, age at the time of trauma, type of trauma, type of post-trauma sequelae, trauma recurrence and crown alteration in the permanent successors. No statistically significant associations were found between permanent successor's crown alteration and gender, age at the time of trauma, post-trauma sequelae or trauma recurrence (p>0.05). Significant associations were found between severe trauma (crown fracture with pulp exposure, lateral luxation, intrusion and extrusion) in the primary incisors and permanent successor's crown alteration (p<0.05). Multivariate analysis revealed an association between severe trauma to the primary incisors and permanent successor's crown alteration (OR: 4.1 - IC: 1.7-10.1). Alterations in the crown of permanent successors are associated with severe trauma to the primary incisors, as primary teeth affected by severe trauma have a fourfold greater chance of exhibiting permanent successor crown alteration in comparison to primary teeth that had minor trauma.


O objetivo deste estudo foi determinar a prevalência de sequelas nos dentes permanentes, em crianças que tiveram o seu antecessor traumatizado e os fatores associados. O estudo foi realizado com dados clínicos e radiográficos de 173 prontuários de pacientes do Programa de Assistência ao Paciente Traumatizado, Universidade Federal de Santa Catarina (Brasil), totalizando 253 dentes. Os dados coletados foram: gênero, idade no momento do trauma, tipo de trauma, tipo de sequelas pós-trauma, recorrência de trauma e alteração na coroa dos sucessores permanentes. Não houve associação estatisticamente significativa entre alteração na coroa do sucessor permanente e gênero, idade no momento do trauma, sequela pós-trauma e recorrência de trauma (p>0,05). Foram encontradas associações significativas entre trauma grave (fratura coronária com exposição pulpar, luxação lateral, intrusão e extrusão) nos incisivos decíduos e o sucessor permanente com alteração na coroa (p<0,05). A análise multivariada revelou uma associação entre trauma grave nos incisivos decíduos e alteração no sucessor permanente (OR: 4.1- IC: 1,7-10,1). Alterações na coroa dos sucessores permanentes estão associadas com trauma grave nos incisivos decíduos. Dentes decíduos acometidos por trauma grave têm quatro vezes mais chance de apresentar alteração na coroa do permanente em comparação com trauma leve.

ABSTRACT

Introducción: los traumatismos de los dientes anteriores son eventos que suceden con frecuencia, por su gran impacto social y psicológico deben ser considerados como un tema de trascendental importancia, lo cual motivó realizar el estudio. Objetivo: identificar características asociadas con las fracturas dentarias en incisivos superiores permanentes en estudiantes que asistieron al servicio estomatológico de la escuela primaria Lazo de la Vega del municipio Marianao en el año 2009. Método: Se realizó un estudio analítico, en el que se incluyeron los 235 escolares matriculados en la escuela del mismo nombre, entre 7 y 12 años de edad que asistieron a consulta. Se estudiaron las variables edad, sexo, presencia de hábitos bucales deformantes, tipo de fractura dentaria e incisivo traumatizado. Se calculó la frecuencia absoluta, el riesgo a través de la tasa por 100, el riesgo relativo (RR) a través de la razón entre riesgos y se aplicó el estadígrafo X² de Pearson para la asociación entre variables. Resultados: el grupo de edad más afectado es el de 10 a 12 años con un 23,4 por ciento, con predominio del sexo masculino dado por un RR de 2,47 veces más que el femenino. La fractura no complicada de corona aparece con mayor frecuencia con un 61,8 por ciento, el diente mayormente afectado es el incisivo central superior izquierdo con un 51,4 por ciento. La diferencia de riesgo entre los grupos de edades no son significativas, aunque en relación con el sexo las diferencias son muy significativas. Conclusiones: Hubo franco predominio de las fracturas no complicadas y de los incisivos centrales superiores, en particular el izquierdo(AU)


Introduction: traumas of front teeth are frequent events which, because of their social and psychological impact, should be considered a topic of paramount importance. This fact motivated the authors to conduct the study. Objectives: to identify the characteristics associated with dental fractures in permanent upper incisors in students who went to the Stomatology Service of Lazo de la Vega Primary School in Marianao Municipality in the year 2009. Method: an analytical study was conducted in 235 students from 7 to 12 years of age who were enrolled in the school mentioned above who presented to the consultation. The variables studied were: age, sex, presence of deforming buccal habits, type of dental fracture and traumatized incisor teeth. Absolute frequency, the rate/100 risk, and the relative risk (RR) through the ratio among risks were calculated and the Pearson's X2 statistics was applied for the association among variables. Results: the most affected age group was from 10 to 12 years with a 23.4 por ciento, predominating the male sex due to a RR 2.47 times higher than the female sex. The non complicated crown fracture was the most frequent one with a 61.8 por ciento, the most affected tooth is the left upper central incisive, with a 51.4 por ciento. The risk difference between the age groups was not significant, although in relation to the sex, the differences are highly significant. Conclusions: there was a marked predominance of the uncomplicated fractures and the upper central incisors, particularly the left ones(AU)

ABSTRACT

Two cases are reported in which incomplete placement of 4 mm mineral trioxide aggregate (MTA) plug was performed unintentionally at the apical third of permanent immature teeth with open apex and apical periodontitis. As confirmed radiographically, there were gaps between MTA and dentinal walls along the MTA-dentin interface. After setting of MTA was confirmed, endodontic treatment was completed and access was sealed with composite resin. At 6 to 16 months follow-up examinations, formation of dentin in contact with the MTA surface, as well as apical closure and periapical healing were ideied radiographically for both cases. The results of these cases showed that apical barrier formation and complete periapical healing is possible despite the incomplete apical placement of the MTA plug. This might be due to the biological properties of the MTA. Even so, an incomplete three-dimensional placement of the filling material is not advocated.

ABSTRACT

Introdução: apesar do traumatismo dentário ser uma das principais causas de perda de dentes permanentes, fraturas radiculares são relativamente incomuns nessas situações. Objetivo: esse trabalho tem por objetivo relatar um caso clínico de fratura radicular horizontal decorrente de traumatismo dentário e discutir suas implicações clínicas. Métodos: a fratura radicular horizontal ocorreu no terço médio do incisivo central superior com afastamento dos fragmentos. O dente foi diagnosticado com necrose pulpar, sendo, então, realizado o tratamento endodôntico. Resultados: após dois anos de proservação, por meio de tomadas radiográficas e tomográficas, não foram constatadas complicações radiculares, ou sintomatologia dolorosa, demonstrando a importância de um diagnóstico correto, que resulte num bom prognóstico, preservando a estética e a integridade psicológica do paciente.
