One case of complicated crown root fracture of upper anterior teeth managed by multidisciplinary joint approaches.

Complicated crown root fracture is a serious combined fracture of the enamel, dentin, and cementum in dental trauma. The treatment method is complicated. During the procedure, the condition of pulp, periodontal, and tooth body should be thoroughly evaluated, and a multidisciplinary approach combined with sequential treatment is recommended. This case reported the different treatment and repair processes of one case of two affected teeth after complicated crown root fracture of upper anterior teeth, including regrafting of broken crown after flap surgery at the first visit, direct resin repair to remove broken fragments, and pulp treatment and post-crown repair at the second visit. After 18 months of follow-up, the preservation treatment of the affected teeth with complicated crown root fracture was achieved. Therefore, fragment reattachment and post-crown restoration are feasible treatment options for children with complicated crown root fracture.

Traumatic dental injuries over an 8-year period at a German dental center: a retrospective overview and cross-sectional analysis.

BACKGROUND/AIM: The aim of this study was to analyze a population of patients who had suffered from traumatic dental injuries (TDIs) by using different patient-, trauma- and treatment-related parameters. MATERIAL AND METHODS: All dental records of patients ≥ 3 years old who had presented at the dental emergency service between Jan 1, 2009 and Dec 31, 2016 for the treatment of dental trauma were analyzed. A total of 2758 patients were invited for a recall examination at the Department for Dental Surgery and Implantology, ZZMK Carolinum, Goethe University Frankfurt, Germany; of these, 269 patients attended their recall appointments. RESULTS: The enrolled patient population consisted of 1718 males and 1040 females, with a mean age of 19.63 years (median 12.00 ± 17.354 years). A total of 4909 injured teeth were assessed, with a mean of 1.78 injured teeth per patient (median 2.00 ± 1.279). Males were found to be more frequently affected by TDIs compared to females (1.65:1). The majority of these injuries occurred in the first two decades of life (66.1%; n = 1824). The majority of the patients presented for initial treatment within 24 h of their accident (95.7%). The most frequent TDIs were isolated luxation injuries 49.4% (n = 2426) and isolated crown fractures 30% (n = 1472). Combination injuries were diagnosed in 20.6% of the cases (n = 1011). CONCLUSIONS: Based on the findings of the present analysis, it can be concluded that males were more frequently affected by TDIs than females. Most patients had suffered from TDI before they had turned 10 years of age. Overall, the enamel-dentin fracture was found to be the most frequent injury, followed by concussions and lateral luxations.

Dental and Dentoalveolar Injuries in the Pediatric Patient.

Dental and dentoalveolar injuries are common in the pediatric population. Management is predicated on the type of tooth injured (primary or permanent), extent of injury, the dental and behavioral age of the patient, and ability of the patient to tolerate treatment. Although many dental injuries occur in isolation, a systematic evaluation of the patient is mandatory to confirm the absence of basal bone fractures of the maxilla or mandible, traumatic brain injury, cervical spine injury, and/or facial soft tissue injury. Long-term follow-up is paramount to achieving a functional occlusion and optimal dental health following injury.

Management of transverse root fractures in dental trauma.

The management of complex dental trauma can be modulated according to the emergencies that may arise over time. Clinical management of transverse root fractures may require different therapies based on situations, such as delay and error in the treatment of an avulsion trauma associated with apical third root fracture, patient's poor compliance, or external and internal root resorption. The primary aim of this article was to review studies regarding root fractures in the permanent dentition and root fracture management. The secondary aim was to present the inflammatory reaction and the complications (i.e., infections) that may occur if the International Association for Dental Traumatology (IADT) guidelines are not followed. In addition, a scenario is devised in which endodontic surgery, despite the baseline patient's conditions and negative prognosis, can help to inhibit the inflammatory root resorption and allow the preservation of soft and hard tissues within a long follow-up from the injury, for the purpose of demonstrating the next possible implant-prosthetic rehabilitation.

Abordagem multidisciplinar no tratamento de incisivo lateral com fratura oblíqua e lesão periapical: relato de caso clínico / Multidisciplinary approach in the treatment of lateral incisor with oblique fracture and periapical injury: clinical case report

Casos de fraturas dentárias oblíquas muitas vezes possuem um prognóstico desfavorável, geralmente com indicação da extração do elemento dental. O presente artigo visou relatar o tratamento do caso clínico de um paciente do sexo masculino, 12 anos, que compareceu à Unidade de Saúde Bucal do Hospital Universitário de Brasília com encaminhamento de extração do dente 12, apresentando fratura oblíqua que se estendia subgengivalmente na face vestibular. O trauma havia ocorrido há três anos e o paciente havia sido submetido a diversas intervenções endodônticas, apresentando no momento da consulta inicial por nossa equipe uma lesão periapical extensa. Após a realização da anamnese, exame clínico e radiográfico, foi adotada uma abordagem multidisciplinar conservadora com a manutenção do dente e a realização da enucleação da lesão periapical por meio de intervenção cirúrgica e posterior reabilitação. Em uma mesma sessão, foi realizada a obturação do conduto com cone de guta percha e cimento sealer 26 e a cirurgia parendodôntica juntamente com a apicoplastia. Uma semana após a intervenção cirúrgica foi realizada restauração classe IV com resina composta baseada no enceramento dos modelos de diagnóstico montados em articulador. Com base em uma avaliação criteriosa e multidisciplinar, foi possível adotar uma abordagem conservadora no caso em questão, com a manutenção e reabilitação de um dente permanente em um paciente jovem, evitando a indicação de exodontia(AU)

Cases of oblique dental fractures often have an unfavorable prognosis, usually with the indication of extraction of the dental element. The present article aimed to report the treatment of the clinical case of a 12-year-old male patient, who attended the Oral Health Unit of the Hospital Universitário de Brasília with a referral for extraction of tooth 7, presenting an oblique fracture that extended subgingivally on the labial surface. The trauma had occurred three years ago and the patient had undergone several endodontic interventions, presenting an extensive periapical lesion at the time of the initial consultation by our team. After anamnesis, clinical and radiographic examination, a conservative multidisciplinar approach was adopted with the maintenance of the tooth and the enucleation of the periapical lesion through surgical intervention and subsequente rehabilitation. In the same session, the conduit was filled with gutta-percha cone and sealer cement 26 and parendodontic surgery was performed together with apicoplasty. One week after the surgical intervention, class IV restoration was performed with composite resin based on the waxing of the diagnostic models mounted on an articulator. Based on a careful and multidisciplinary evaluation, it was possible to adopt a conservative approach in the case in question, with the maintenance and rehabilitation of a permanent tooth in a young patient, avoiding the indication of extraction(AU)

Protección pulpar directa y posterior apexogénesis: informe de un caso clínico / Direct pulp capping followed by apexogenesis: a clinical case report

Objetivo: Describir el tratamiento de un paciente que pre- sentó un incisivo superior permanente con exposición pulpar y desarrollo radicular incompleto utilizando Biodentine como material para la protección pulpar directa. Caso clínico: Un paciente de 9 años fue derivado para la evaluación y el tratamiento del diente 11. El examen clínico y radiográfico reveló la presencia de una fractura amelodentinaria, con exposición pulpar y desarrollo radicular incompleto. Luego de lavar y desinfectar el área de la fractura, se protegió la pulpa expuesta con Biodentine y se restauró la cavidad. El paciente fue citado para control a los 18 y 25 meses. En los controles se comprobó que el diente se mantuvo asintomático y funcional. Luego de 25 meses, el examen clínico y radiográfico confirmó la presencia de pulpa vital y el completo desarrollo del remanente radicular. Los resultados obtenidos en el presente caso clínico sugieren que el empleo de Biodentine puede ser considerado como una valiosa alternativa para la protección de la pulpa ex- puesta en dientes con desarrollo radicular incompleto (AU)

Aim: To describe the treatment of a patient that presented a permanent maxillary central incisor with pulp exposure and incomplete root formation, using Biodoentine as the material for direct pulp protection. Clinical case A 9-year-old male patient was referred for evaluation and treatment of tooth 11. The clinical and radio-graphic examination revealed the presence of a dentinoe- namel fracture, with pulp exposure and incomplete root for- mation. After cleaning and disinfecting the area, the exposed pulp was protected with Biodentine and the cavity was re- stored. The patient was scheduled for control after 18 and 25 months. In these evaluations, it was confirmed that the tooth remained asymptomatic and functional. After 25 months, the clinical and radiographic examination showed the presence of vital pulp and a completed development of the root. The obtained results of this clinical case suggest that Biodentine can be considered a valuable alternative for pulp capping in teeth with incomplete root formation (AU)

Effects of irradiation, restoration and crown fracture type on the maximum load to fracture traumatized incisors: An ex vivo study.

BACKGROUND/AIMS: Radiotherapy makes teeth prone to tooth fractures. However, the relationship between radiotherapy and maximum load to fracture teeth that suffered a crown fracture is not fully understood. The aim of this study was to evaluate the influence of fracture type, radiation dose, fracture time, and their interactions on maximum load to fracture irradiated teeth. MATERIAL AND METHODS: A total of 140 permanent incisors were divided into two fracture type groups (uncomplicated and complicated) each of which included seven radiation dose subgroups (0, 10, 20, 30, 40, 50, and 60). The test groups were exposed to high-energy X-ray at 2 Gy/day, 5 days/week for a total dose of 10-60 Gy. Control groups were not irradiated. The load where the specimen started to break was obtained two different times. The 1st fracture was performed after radiation therapy, and the 2nd fracture was performed after the restoration of these samples. RESULTS: Fracture type had no effect on the maximum load to fracture. In contrast, the maximum load to fracture teeth decreased with increasing radiation doses. Maximum load to fracture the restored teeth was lower than the 1st fracture results. The general linear model procedure revealed a significant interaction between radiation dose and fracture time. Similarly, there was a significant interaction between the fracture type, radiotherapy dose, and fracture time. Maximum load values of teeth with complicated crown fractures restored with fiber posts and composite were not affected by radiation. CONCLUSION: Teeth that have been subjected to radiotherapy have an increased risk of fracture during dental trauma. However, restoration of the irradiated teeth with fiber posts and composite resin did not affect the maximum load required to fracture them.

Orthograde apical plug in a traumatized tooth with necrotic pulp and immature apex using calcium silicate cement: A case report.

This case report describes dental management of a 15- year-old boy, undergoing treatment for Thalassaemia Major and Acute Myeloid Leukaemia with bone marrow transplant and immuno-suppressants. During the course of his treatment the patient developed a swelling in anterior maxilla and therefore was referred by the primary physician for evaluation. This case report highlights the management of medically compromised patients in a tertiary care hospital in which apexification was carried out in a permanent immature tooth utilizing MTA as an immediate apical plug.

Management of a Subgingivally Fractured Maxillary Central Incisor by Reattachment Technique.

Reattachment of a fractured fragment to the remaining tooth is challenging but one of the best treatment protocols in regards to aesthetics, function as well as patients acceptance. If the original tooth fragment is retained following fracture, the natural tooth structures can be reattached using adhesive protocols to ensure reliable strength, durability and aesthetics. This case report will discuss a 13 years old boy with a complicated crown-root fracture of maxillary right central incisor tooth. The procedure used to repair the fracture regarding this case including flap surgery with endodontic treatment. The root canal was filled with a root canal sealer and gutta-percha. After root canal obturation, fragment was reattached with an adhesive tooth reattachment technique. After 6 months evaluation, clinical and radiographic examinations showed a stable re-attachment, good aesthetic and healthy periodontium.

Dental Injuries and Management.

Traumatic dental injuries affect 1 to 3% of the population, and disproportionately affect children and adolescents. The management of these injuries incorporates the age of patients, as children between 6 and 13 years of age have a mixed dentition. This helps to preserve the vitality of teeth that may be salvaged after a traumatic event. The clinical examination of these cases involves a thorough examination of the maxilla and mandible for associated fractures and any lodged debris and dislodged teeth or tooth fragments. The objective is to rule out any accidental aspiration or displacement into the nose, sinuses, or soft tissue. After ruling out any complications, the focus is on determining the type of injury to the tooth or teeth involved. These include clinical examination for any color change in the teeth, mobility testing, and testing for pulp vitality. Radiographic evaluation using periapical, occlusal, panoramic radiographs, and cone beam computed tomography is performed to view the effect of trauma on the tooth, root, periodontal ligament, and adjoining bone. The most commonly used classification system for dental trauma is Andreasen's classification and is applied to both deciduous and permanent teeth. Managing dental trauma is based on the type of injury, such as hard tissue and pulp injuries, injuries to periodontal tissue, injuries of the supporting bone, and injuries of the gingiva and oral mucosa. Hard-tissue injuries without the involvement of the pulp typically require restoration only. Any pulp involvement may require endodontic treatment. Fractures involving the alveolar bone or luxation of the tooth require stabilization which is typically achieved with flexible splints. The most common procedures employed in managing dental injuries include root canal/endodontics, surgical tooth repositioning, and flexible splinting. Recognition and treatment of these injuries are necessary to facilitate proper healing and salvage of a patient's natural dentition, reducing future complications to patients.

Surgical Treatment of a Cemental Tear-Associated Bony Defect Using Hyaluronic Acid and a Resorbable Collagen Membrane: A 2-Year Follow-Up.

INTRODUCTION: A cemental tear (CeT) is a special type of surface root fracture that may cause periodontal and even periapical tissue destruction. Unfortunately, there is limited knowledge as to how these rare cases can effectively be treated. The present case is believed to be the first reported in the literature treating a bony defect caused by a cemental tear with hyaluronic acid (HA) and a collagen membrane. The aim of this case report is to present a regenerative surgical approach with clinical and tomographic success and stability at 2-year follow-up. CASE PRESENTATION: A 61-year-old patient presented with spontaneous pain and gingival swelling over his right central maxillary incisor. Radiographically, a radiolucent area was observed in the medial third between both central incisors. The tomographic evaluation showed a buccal bone dehiscence and a bony defect. Once the differential diagnosis with an endodontic-periodontal lesion and root fracture was performed, CeT was the presumptive diagnosis. During the exploratory flap surgery, a small root fragment (CeT) on the mesial side of the tooth was founded and removed. The bony lesion was treated with hyaluronic acid (HA) and a resorbable collagen membrane. At 2-year follow-up clinical, radiographic, and tomographic success was observed. CONCLUSION: A CeT-associated bony defect could be successfully treated after removing cemental fragments and performing a regenerative approach using HA and a resorbable collagen membrane.

Fractura radicular de tercio medio: tratamiento y cinco años de seguimiento / Treatment and 5-year follow-up of root fractures in the middle third

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)

Extrusión: una alternativa de tratamiento de la fractura corono-radicular / Extrusion: an alternative for the treatment of crown-root fracture

La extrusión dentaria o erupción forzada es una opción de tratamiento con enormes ventajas cuando nos vemos obligados a tratar fracturas corono-radiculares. Se define como el movimiento en dirección coronal a través de la aplicación de fuerzas ligeras y continuas para provocar cambios en los tejidos blandos y hueso. La extrusión dental forzada amplía las alternativas en cuanto a la rehabilitación futura del paciente, ya que se puede optar por la restauración periférica total con anclaje del resto radicular, o bien por la exodoncia posterior a la extrusión, con la consecuente mejoría de las condiciones del tejido óseo para una posterior rehabilitación implanto-asistida. Presentación de caso clínico, pieza dentaria 2.2 con fractura corono-radicular en la cual se realizó tratamiento de erupción forzada y rehabilitación protésica (AU)

Extrusion or forced eruption es a treatment option with enormous advantages when we are forced to treat crown-root fractures. It is defined as the movement in the coronal direction through the application of light and continuous forces to cause changes in the soft tissues and bone. Forced dental extrusion expands the alternatives regarding the future rehabilitation of the patient, since it is possible to choose either total peripheral restoration with anchoring of the radicular rest of the post-extrusion extraction, with the consequent improvement of bone tissue conditions for subsequent implant-assissted rehabilitation. Presentation of a case report: tooth 2.2 with a crown-root fracture in which forced eruption and prosthetic rehabilitation were performed (AU)

Reabilitação em dentes anteriores com pinos de fibra de vidro e coroas metal free: relato de caso / Rehabilitation on previous teeth with glass fiber pins and metal free crowns: case report

Objetivo: descrever uma reabilitação em incisivos superiores por meio da associação de coroas totais de cerâmica e retentor intrarradicular de fibra de vidro. Caso clínico: paciente P. C. G., gênero masculino, de 49 anos de idade, leucoderma, insatisfeito com a estética dos dentes anteriores devido a traumatismo dentário e fraturas recorrentes das restaurações. Após a realização de anamnese, exames clínico e radiográfico, contataram-se restaurações de resina composta insatisfatórias nos dentes anteriores, grandes diastemas entre os dentes e leve inflamação gengival. Para o plano de tratamento, optou-se por realização do tratamento endodôntico dos elementos 12 e 22, pino de fibra de vidro no dente 21, e coroas totais de dissilicato de lítio em todos os incisivos superiores. Considerações finais: com a finalização do tratamento e o retorno do paciente à clínica após seis meses, pode-se observar um tecido gengival sadio e o paciente muito satisfeito com os resultados obtidos. (AU)

Objective: to describe a rehabilitation in upper incisors through the association of total ceramic crowns and intra-radicular fiberglass retainer. Clinical case: patient P. C. G. male sex, 49 years old, leucoderma, dissatisfied with the aesthetics of the anterior teeth due to dental traumatism and recurrent fractures of the restorations. After anamnesis, clinical and radiographic examination, unsatisfactory composite resin restorations on anterior teeth, large diastema between teeth and mild gingival inflammation were contacted. For the treatment plan, we chose to perform endodontic treatment of elements 12 and 22, glass fiber pin on tooth 21, and total crowns of lithium disilicate on all upper incisors. Final considerations: with the completion of the treatment and return of the patient to the clinic after six months, a healthy gingival tissue can be observed and the patient very satisfied with the results obtained.

Combined orthodontic, surgical, and restorative approach to treat a complicated crown-root fracture in a maxillary central incisor.

This case report shows the treatment of a severe traumatic tooth injury. For the maxillary right central incisor, the trauma was considered a complicated crown-root fracture. The level of the fracture line, the length of the remaining root segment, and the presence and condition of the tooth fragment determined the type of therapy. Traumatized teeth with fractures below the alveolar crest are often considered hopeless. As this report shows, the treatment of a complicated crown-root fracture in the esthetic region can be challenging. Orthodontic extrusion and crown-length surgery were performed to bring the fracture line above the alveolar bone crest. A multidisciplinary approach was required for complete rehabilitation of the traumatized maxillary incisor. Suggestions are made to improve treatment planning of complicated crown-root fractures.

Direct resin composite restoration of maxillary central incisors using a 3D-printed template: two clinical cases.

BACKGROUND: Three-dimensional (3D) printing technology is used widely in dentistry for applications including implant surgery, oral and maxillofacial surgery, orthognathic surgery, endodontics and prosthodontics. Using a 3D-printed template makes performing the repair procedure faster and more convenient. The aesthetic restoration of anterior teeth can recover facial beauty, enhance speaking and chewing functions and improve the quality of life of the patient. CASE PRESENTATION: This article describes two kinds of clinical cases including fractured teeth and dental caries. In both, a 3D-printed template was used for direct resin composite restoration of maxillary central incisors. A 3D-printed template was built using the following 3-step process: data acquisition was conducted via intra-oral scanning, virtual modeling was performed using an imaging process, and manufacturing was performed using a 3D printer. Aesthetically restoring the maxillary incisors with the assistance of the 3D-printed template achieved the anticipated results, and the patients were very satisfied with the effect. CONCLUSIONS: The direct resin composite restoration of maxillary central incisors using a 3D-printed template represents a rapid, convenient, aesthetic and functional option for treating maxillary central incisors. A 3D-printed template is therefore an acceptable and reliable alternative to traditional direct composite restoration of maxillary central incisors including fractured teeth and dental caries.

Bones heal, teeth don't! The involvement of dentists in the acute and long-term management of patients injured in the Manchester Arena Bomb.

This paper outlines the involvement of dentists in the treatment of patients following the terror attack at Manchester Arena on 22 May 2017. It predominantly describes the role of the authors - a paediatric dental consultant and maxillofacial surgery dental core trainee (DCT). As a result of the incident a number of patients suffered oro-facial injuries, with many treated at Central Manchester Foundation Trust Hospitals' Manchester Royal Infirmary and Royal Manchester Children's Hospital. The major incident response of the trust is discussed, as are the presentation of blast injuries and corresponding NHS guidance. Two paediatric cases present the role of the paediatric dental consultant in the acute, intermediate and long-term management of these patients. The presentation of unique dento-alveolar injuries in the context of other trauma and their subsequent treatment demanded true multidisciplinary management. The importance of teeth and oral health to physical and psycho-social wellbeing and recovery was clear and recognised by other teams involved in the patients' management. The experience reinforced the overall impact dental health has on physical and psycho-social health, and how a holistic approach is integral to treatment of major trauma.

Importance of knowledge of the management of traumatic dental injuries in emergency departments.

BACKGROUND: Hospital emergency departments (EDs) are confronted with managing dental emergencies of both traumatic and non-traumatic origin. However, the literature suggests inadequate knowledge of the management of traumatic dental injuries (TDIs) among medical professionals. The aim of this study was to investigate the knowledge and attitudes regarding management of TDIs among Istanbul ED physicians. METHODS: Surveys were distributed to emergency departments (ED) directors and their physicians. The survey contained questions about their characteristics and tested their knowledge of managing dental trauma. RESULTS: A total of 126 surveys (13 ED directors and 113 physicians) were returned and included in the analysis. ED physician's knowledge of the appropriate management of crown fractures and avulsion was generally good (p=0.221), but poor for luxation injuries (p=0.0001). Physicians were more likely to have a better knowledge about permanent teeth than about primary teeth (p=0.027). CONCLUSION: Education, monitoring, improved availability of resources, and disciplinary measures in cases of poor compliance are necessary to improve TDI management in hospitals, especially among physicians.
