Terapia Pulpar Vital en Diente con Fractura Coronaria Complicada

La fractura coronaria es el traumatismo dentoalveolar (TDA) más frecuente en la dentición permanente. Cuando existe exposición pulpar, se conoce como fractura coronaria complicada (FCC). Actualmente, en estos casos, se recomienda realizar terapias que permitan preservar la vitalidad del tejido pulpar, tanto en dientes maduros como inmaduros. El presente reporte describe el caso de un paciente de 9 años con FCC en diente 2.1, donde se realizó tratamiento con terapia pulpar vital (pulpotomía de Cvek), y adhesión de fragmento dentario. En los controles posteriores al TDA (1 semana, 4 meses, 1 y 2 años) el diente estaba asintomático, se observó formación de puente dentinario y continuación de desarrollo radicular con cierre apical, indicios de que el tejido pulpar se mantuvo vital. En este caso se destaca la importancia del diagnóstico, tratamiento adecuado, junto al seguimiento de un diente con desarrollo radicular incompleto.

Crown fracture is the most frequent dental traumatic injury (DTI) in permanent dentition. When there is pulp exposure, it is known as a complicated crown fracture. Currently, in these cases, it is recommended to carry out therapies that allow preserving the vitality of the pulp tissue, both in mature and immature teeth. This report describes the case of a 9-year-old patient with a complicated crown fracture in tooth 2.1, who underwent treatment with vital pulp therapy (Cvek pulpotomy), and adhesion of the dental fragment. In follow-up sessions (after 1 week, 4 months, 1 and 2 years), the tooth was asymptomatic. It was observed dentin bridge formation and the continuation of root development with apical closure, indications that the pulp tissue has remained vital. In this case, the importance of proper diagnosis and treatment is highlighted, together with the follow-up of a tooth with incomplete root development.

The outcome of partial pulpotomy in traumatized permanent anterior teeth – A systematic review and meta-analysis

Background: Partial pulpotomy is a procedural intervention that can maintain the vitality of pulp during the management of traumatized permanent teeth with pulpal involvement. Aim: To evaluate whether partial pulpotomy can be considered a reliable conservative treatment option for treating traumatized permanent anterior teeth with pulpal involvement. Methodology: A computerized systematic search was performed in PubMed, Science Direct, Cochrane, and LILACS databases from 1980 to May 2021. Five studies were included in the final analysis. Quality assessment, Meta?analysis, and Publication bias of the studies were evaluated. This systematic review was registered in PROSPERO (ID – CRD42021262031). Result: The comprehensive Meta?Analysis Software was used. The test of the heterogeneity was analysed using Cochran’s Q statistics. The Q value was 7.186 (df = 6) with a P value of 0.3 and I2 as 16.5%. The studies were considered homogenous, and the fixed?effect model showed an overall point estimate of 0.89 with a 95% confidence interval (0.86–0.91). The Begg and Egger funnel plot indicated that there was no publication bias in the included studies. Conclusion: Evidence indicates that partial pulpotomy may be considered a reliable definitive treatment option in asymptomatic traumatized permanent anterior teeth with exposed pulp rather than total pulpotomy.

Conservative and esthetic approach in crown fracture of maxillay anterior tooth: tooth fragment reattachment

Crown fractures are the most frequent traumatic injuries to permanent teeth and mainly involve the maxillary incisors due to their exposed position in the dental arch. One option for managing crown fractures, when the tooth fragment is present and in good condition, is reattachment of the fragment to its original position. This paper reports on three crown fracture cases in which successful esthetic and functional results were achieved by reattachment of the tooth fragment.

Tooth fragment re-attachment in fracture with biological width violation: case

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.

Natural Rehabilitation of Fractured Anterior Tooth Using Reattachment, a Single Visit Endo- Esthetic Approach- A Case Report.

Anterior teeth crown fracture of a growing child requires immediate attention, not only because of damage to the dentition but also due to unsightly smile and facial appearance affected by trauma to the child. Thus esthetic management of anterior tooth fracture has been one of the most important aspects of dentistry and when it has to be done using the tooth’s own structure, it sounds psychologically more acceptable. And with the development of resin-based materials that offer high bond strength values, it has made possible to undoubtedly go for reattachment technique with ease. For further simplification, single visit rotary endodontics using ProTaper Universal system is recommended as it is designed to offer better features like flexibility and less chairside time than hand instrumentation. Presented here is one such case in which a combination of single visit rotary endodontics and adhesive reattachment using flowable composites has been carried out to reframe the broken tooth and comply with the patient’s concern. The treatment was found to be successful both functionally and aesthetically at the 18-month follow-up.

Restoration of Permanent Central Incisors with Porcelain Laminate Veneers in a Paediatric Patient: A Clinical Report.

School children often encounter traumatic injuries like a crown fracture. They create serious functional, esthetic and psychological problems. Achievement of promising restoration that preserves its aesthetics and strength is the greatest desire for both children and their parents and is a challenging task for the dentist. The restorative options in these cases usually include composite resin and porcelain laminate veneers. This article describes treatment of a paediatric patient with porcelain laminate veneers for restoring unaesthetic maxillary anterior teeth.

Orthodontic Considerations for Traumatized Permanent Teeth.

Objectives: The aim of this article is to shed the light on the recommendations for orthodontic movement of traumatized teeth since traumatic dental injuries forms a challenge to the orthodontists worldwide. We tried to create a kind of treatment protocol in different kinds of traumas depending on available case reports and text books in this field. Materials and Methods: Searching included dental text books and electronic searching (pubmed, medline, embase and central databases). Inclusion criteria were: Dental, oral and maxillofacial trauma oriented articles and text books. Results: 56 articles and text books met the searching criteria. Limitation: This article is basically depending on case reports. It is obvious that there is no clinical randomized studies in third field, because it depends on accidents and trauma, thus the reader will not find a discussion or a part in this article to compare between the different findings and opinions. Conclusion: Generally, minor traumatic injuries require at least three months observation period before starting orthodontic movement. When the trauma is of greater severity at least six months observation period is needed as a minimum. Teeth with horizontal root fracture should be observed for one to two years before starting orthodontic movement. More research should be done in this field. Clinical Significance: Dental traumatic injuries have a high prevalence worldwide, and it affects children, adolescents and adults. Since orthodontic tooth movement is principally a periodontal ligament phenomenon, the orthodontist should be able to deal with the periodontal ligament injuries that might happen before or during the course of orthodontic treatment.

Avaliação dos tratamentos propostos pelos dentistas em casos de fraturas coronárias / Evaluation of treatments plans for managment of crown fractures proposed by dentists

Introdução: a odontologia prioriza a manutenção e integridade dos dentes na boca e a ocorrência de traumatismos dentais vem dificultando o cumprimento desta meta, uma vez que suas consequências envolvem danos funcionais, estéticos, psicológicos, sociais e terapêuticos, além dos altos custos para a reabilitação e acompanhamento por longos períodos de tempo. Objetivo: avaliar o conhecimento dos cirurgiões dentistas da região metropolitana de Juazeiro do Norte sobre as condutas clínicas baseadas nos planos de tratamentos propostos por estes profissionais sobre fraturas coronárias com ou sem exposição pulpar. Método: a partir de um questionário descritivo, foram abordadas questões referentes ao perfil dos profissionais entrevistados e procedimentos empregados na conduta frente a fraturas coronárias. Setenta e cinco questionários foram devidamente preenchidos, sendo 34 mulheres e 41 homens. Resultados: dos entrevistados 13 relataram nunca terem atendido casos de trauma dental, 26% relataram serem incapazes de tratar todos os casos de traumatismo dentário. E mesmo a maioria tendo formação especializada, grandes dificuldades foram encontradas nos planos de tratamento propostos em relação a fraturas mais complicadas. Discussão: as lesões dentais traumáticas envolvendo tecidos duros e de sustentação podem representar padrões de cicatrização bastante complexos. As lesões traumáticas do tipo fraturas coronárias apresentam um prognóstico favorável para a manutenção da vitalidade pulpar em relação às fraturas coronárias complicadas. As fraturas corono-radiculares com ou sem envolvimento pulpar, foram as que apresentaram mais indicações inadequadas de tratamento, provavelmente por necessitarem de uma abordagem multidisciplinar. Conclusão: considera-se primordial a multidisciplinaridade durante a formação acadêmica do clinico geral, bem como o aperfeiçoamento ao atendimento a pacientes com trauma dental. (AU)

Introduction: Dentistry prioritizes the maintenance and integrity of teeth in the mouth and the occurrence of dental trauma is hampering the achievement of this goal, since its consequences involve functional, aesthetic, psychological, social and therapeutic damage, in addition to high costs for rehabilitation and monitoring for extended periods of time. Objective: The objective of this study was to assess the knowledge of dentists in the metropolitan region of Juazeiro do Norte on the clinical management based on treatment plans proposed by these professionals on crown fractures with or without pulp exposure. Methods: For that, starting from a descriptive questionnaire, some questions regarding the profile of inquired professionals and procedures used in the performance of treatment of crown fractures. Results: Seventy-five questionnaires were fully completed, 34 women and 41 men. Only 13 reported ever having met cases of dental trauma, 26% reported being unable to deal with all cases of dental trauma. And even most having specialized training, great difficulties were encountered in the proposed treatment plans for the most complicated fractures. Discussion: Traumatic injuries involving pulp and periapical tissues can represent very complex healing patterns. The crown fractures have a favorable prognosis for the maintenance of pulpal vitality in relation to coronary complicated fractures. The corono-root fractures with or without pulp involvement, were the ones that had more inadequate treatment, probably because they require a multidisciplinary approach. Conclusion: it is essential for multidisciplinary academic training of general practitioner as well as improving service to patients with dental trauma. (AU)

Management of Crown Root Fracture by Multi-disciplinary Approach-A Case Report

Trauma to anterior tooth is a relatively common event. Crown-root fractures are often difficult to treat and are time consuming, which causes psychological trauma to the patient during that period. Fracture of tooth after trauma is distressing to a person because of the discomfort and pain due to pulpal injury. Crown root fractures of anterior teeth cause concomitant periodontal injury and there will be concern about appearance and aesthetics. Management of pulpal and periodontal tissue relieves pain and restoration of tooth form regains patient's confidence. Restoration of fractured tooth will be accepted readily if it is minimally invasive, less expensive, and aesthetically acceptable. Reattachment is an option for restoration of anterior teeth compared to other artificial replacements because of its appearance as natural. This method is favourable when the fractured fragment is intact and available. Utilization of pulp space for retention of fragment is achieved by the insertion of a dentine bonding post. This case report describes a case of tooth reattachment after trauma in which the pulp space is utilized to bond a fibre-reinforced post for retention after periodontal tissue management.

Reattachment of coronal fragment using fiber reinforced post.

Anterior crown fractures are a common form of injury that mainly affects children and adolescents due to their position in the oral cavity especially in the maxillary arch. Reattachment of original tooth fragment to the fractured tooth forms a relatively quick, biologic and esthetic restoration. A 28 years old male reported to the Department of conservative dentistry & endodontics with a complex crown fracture of 21 and 22 one day after the trauma had occurred. Following endodontic treatment, a glass fibre post was used to increase retention and distribute stresses along the tooth. The dental restoration was completed using the original fragment and a dual cure resin composite. Clinical and radiographic examination at 3, 6 & 11 months recall showed the glass fiber post and restoration was in place, indicating the success of the treatment in maintaining the fractured tooth.

Most of the patients with dental trauma assisted the consultation 24 hours after the lesion occurrence.

Frequência de reabsorção radicular inflamatória decorrente de trauma em dentes anteriores / Inflammatory root resorption frequency due to trauma in anterior teeth

Objetivo: a reabsorção radicular inflamatória é uma das consequências do traumatismo dentário, sendo a detecção e o tratamento precoces determinantes na limitação de seus danos. Assim, o objetivo deste estudo foi investigar, em dentes anteriores permanentes traumatizados, a prevalência de reabsorção radicular inflamatória, relacionando-a com os diferentes tipos de traumatismos nos tecidos de sustentação e dentários. Sujeitos e método: os dados relativos à reabsorção inflamatória foram coletados a partir de 111 dentes, nos prontuários de 74 pacientes de um serviço de tratamento de trauma dental da FO/UFPel, no período de 2005 a 2011. Foram registrados, ainda, o sexo e a idade dos pacientes, os dentes envolvidos no trauma, a presença de rizogênese completa ou não e o tempo inicial para o aparecimento da reabsorção. A avaliação dos dados foi realizada por estatística descritiva e teste qui-quadrado, com correção de Yates, ao nível de significância de 5%. Resultados: a reabsorção radicular inflamatória foi mais frequente em pacientes do sexo masculino, em incisivos superiores, em dentes com rizogênese completa e nas lesões de menor gravidade nos tecidos dentários e de sustentação. Ainda, as lesões nos tecidos de sustentação, quando não combinadas às fraturas dentárias, apresentaram maior frequência de reabsorção. O tempo inicial para o aparecimento da patologia foi dentro dos primeiros trinta dias após o trauma. Conclusão: é importante diagnosticar detalhadamente os traumas nos tecidos dentários, a fim de verificar o comprometimento dos tecidos de sustentação, devendo a proservação desses casos ser sistemática e contínua para interceptar a reabsorção radicular.

Objective: inflammatory root resorption is one of the consequences of dental trauma so its early detection and treatment are crucial in limiting their damage. Thus, this study aimed to investigate the prevalence of inflammatory root resorption in traumatized permanent anterior teeth, relating it to the different types of trauma in support and dental tissues. Subjects and method: data concerning inflammatory resorption were collected from 111 teeth, in medical records of 74 patients of a dental trauma care in UFPel’s Dentistry School, from 2005 to 2011. Gender and age of patients, teeth involved in the trauma, presence or absence of full rooting, and the initial time of root resorption emergence were also registered. Data assessment was performed by descriptive statistics and chi-square test with Yate’s correction, at significance level of 5%. Results: inflammatory root resorption was most frequent in male patients, in upper incisors, in teeth with complete root formation, and in minor injuries of dental and support tissues. Also, the supporting tissues injury presented higher resorption frequency when not combined with dental fractures. The starting time for pathology emergence was within the first thirty days after the trauma. Conclusion: it is important to thoroughly diagnose the trauma in dental tissues to verify the impairment of support tissues, since the proservation of these cases should be systematic and continuous to intercept root resorption.

Esthetic restoration of subgingival crown-root fractured maxillary anterior tooth using surgical extrusion / 대한치과보철학회지

Surgical extrusion, immediate extrusion following tooth luxation, is a method to preserve one's natural tooth and achieve esthetic restoration without additional periodontal surgery when subgingival dental caries or crown fracture occurs. A 16-year-old male was referred to the clinic from the department of operative dentistry for the esthetic restoration of maxillary left lateral incisor. Due to the crown to root fracture, the tooth was endodontically treated with a buccal crown length of 4 mm. When the palatal flap was elevated, the mesiopalatal cervical fracture area was situated 3 - 4 mm subgingivally. Crown lengthening was achieved through surgical extrusion. After 3 months of clinical observation and provisional restoration, the maxillary left central incisor was restored with all ceramic crown and obtained a satisfactory clinical result.

A Clinical Study of Reattachment of Fractured Young Permanent Anantierior Tooth Fragments / 实用口腔医学杂志

This was a restrospective clinical study of 32 children with fractured anantierior tooth fragments. The teeth was reattached by dual cured resin composite (Panavia F), 3M Z350 resin and 3M siglebond-2 bonding agent for at least 6-month recall examination. Only 2 of the restorations were lost, resulting in a 93.75% overall retention rate. The retention teeth exhibited good esthetics and normal function. The high retention rate in this study suggests that reattachment of fractured anantierior tooth fragments offers a convenient viable restorative option for the clinician.
