Novel management of internal root resorption with vertical root fracture using mineral trioxide aggregate - A case report

Introduction: This case report presents the diagnosis and management of extensive internal root resorption (IRR) in a 17?year?old male patient, with a 9?year?old history of trauma. Method: The affected tooth 21 was associated with vertical root fracture (VRF) and incomplete apex closure with a substantial loss of tooth structure, including dentin and cementum. Encouraged by a healthy periodontal condition, the choice was made to use mineral trioxide aggregate (MTA) to reconstruct and reinforce the resorptive defect and the fractured segment. A composite veneer was placed to enhance the aesthetics. Result: A follow?up of the patient after 2 years revealed healing with a resolution of the lesion. Conclusion: This case report highlights the use of MTA as a lone?standing filling material for the treatment of IRR with VRF in a non?vital immature tooth

A micro-computed tomography evaluation of voids using calcium silicate-based materials in teeth with simulated internal root resorption

OBJECTIVES: The obturation quality of MTA, Biodentine, Total Fill BC root canal sealer (RCS), and warm gutta-percha (WGP) in teeth with simulated internal root resorption (IRR) was evaluated by using micro-computed tomography.MATERIALS AND METHODS: Standardized IRR cavities were created using 40 extracted maxillary central incisor teeth and randomly assigned into 4 groups (n = 10). IRR cavities were filled with MTA, Biodentine, Total Fill BC RCS (bulk-fill form) and WGP + Total Fill BC RCS. Percentage of voids between resorptive cavity walls and obturation material (external void), and inside the filling materials (internal voids) were measured.RESULTS: Total Fill BC sealer in the bulk-fill form presented significantly highest values of external and internal void percentages (p < 0.05). Biodentine showed a significantly lowest external void percentage (p < 0.05). WGP + Total Fill BC RCS presented significantly lower values of internal void percentages than all groups (p < 0.05), except Biodentine (p > 0.05).CONCLUSION: None of the filling materials were created void-free obturation in resorption cavities. Biodentine may favor its application in teeth with IRR over Angelus MTA and bulk-fill form of Total Fill BC.

Treatment of inflammatory internal root resorption with biodentine: a case report

Internal root resorption has been described as a resorptive defect of the internal aspect of the root following necrosis of odontoblasts as a result of chronic inflammation and bacterial invasion of the pulp tissue. Successful treatment outcome depends on early diagnosis, removal of the cause, proper treatment of the resorbed root. The present case report demonstrates the use of biodentine for the management of internal resorption.he aim of this study was to evaluate the efficacy of different lengths of time of passive ultrasonic irrigation (PUI) in removing calcium hydroxide (CH) paste from root canal, using scanning electron microscopy and energy dispersive spectrometry (SEM/EDS).

Management of an internal root resorption on a permanent tooth: a case report / Manejo de una reabsorción radicular interna en una pieza permanente: reporte de caso

Internal root resorption (IRR) is a rare pulp disease. Its etiology involves late pulpal inflammations and trauma, among others. IRR may also show some symptoms, and is usually detected by X-rays. However, its diagnosis is significantly improved by the use of cone beam computed tomography (CBCT). The objective of this case report was to account for the diagnosis and management of an internal root resorption without perforation. The patient, a 26-year-old male, went to the School of Dentistry at Universidad Andres Bello, Concepción, without having symptoms in the tooth 1.1. Anamnesis revealed the presence of previous symptoms. CBCT examination showed absence of bowl-shaped calcified dentin tissue on the inner walls of the root canal with apical lesion but without perforation of surrounding tissues. Endodontic treatment was performed using the following methods: irrigation of the root canal with 2 percent chlorhexidine (CHX) using a Max-i-probe cannula and simultaneous cavitation of the irrigant Then calcium hydroxide (CH) was applied as intracanal medication for a week and Schilder’s technique for vertical compaction was used. The patient was checked after one week and then after six months. He did not have any symptoms. Early diagnosis using modern imaging equipment, appropriate use of ultrasound for chemomechanical debridement and thermoplastic filling techniques contribute to a more favorable prognosis of patients with internal root resorption...

La reabsorción radicular interna (RRI) es una condición pulpar poco común, cuyo origen etiológico incluye procesos inflamatorios tardíos de la pulpa, traumatismos, entre otros; por otra parte ésta podría presentar sintomatología. Generalmente es detectada por hallazgo radiográfico, sin embargo, requiere de un mejor método de diagnóstico por imagen como es la tomografía computarizada cone beam (TCCB). El objetivo de este reporte de caso fue detallar el diagnóstico y manejo de una reabsorción radicular interna sin perforación. El paciente de sexo masculino, 26 años de edad acudió a la Facultad de Odontología de la Universidad Andrés Bello sede Concepción, sin presentar síntomas en el diente 1.1. La anamnesis refirió presencia de sintomatología con anterioridad. La evaluación mediante la TCCB demostró ausencia de tejido dentinario calcificado en forma de cuenco en las paredes internas del conducto radicular con presencia de lesión apical sin evidenciar perforación hacia tejidos circundantes. Se realizó el tratamiento endodóntico, usando los siguientes métodos: el conducto radicular se irrigó con Clorhexidina (CHX) al 2 por ciento usando cánula Max-i-probe y simultáneamente fue realizada la cavitación del irrigante, luego se colocó Hidróxido de Calcio (HC) como medicación intraconducto por una semana. Se usó la técnica de compactación vertical de Schilder más un control del paciente a la semana y a los 6 meses. El paciente no presentó sintomatología. El diagnóstico temprano mediante herramientas imaginológicas contemporáneas, la utilización del ultrasonido para el desbridamiento químico-mecánico y las técnicas de obturación termoplásticas usadas acorde al caso hacen que las piezas con reabsorción radicular interna tengan un pronóstico más favorable...

Endoperiodontal lesion due to communication internal root resorption / Lesão endoperiodontal decorrente de reabsorção radicular interna comunicante

Internal root resorptions are usually non-symptomatic and are discovered occasionally throughperiapical radiographs, revealing a very defined and regular outline. These resorptions are progressive,and eventually perforate the periodontium. The present work describes the treatment of a clinicalcase of internal root resorption with periodontal communication, outlining the interrelation betweenperiodontal surgery and endodontic therapy.

As reabsorções internas são normalmente assintomáticas e descobertas ocasionalmente atravésde radiografias periapicais, onde revelam um contorno bem definido e regular. Estasreabsorções são progressivas e eventualmente perfuram o periodonto. O presente trabalhodescreve o tratamento de um caso clínico de reabsorção radicular interna com comunicaçãoperiodontal onde se fizeram necessárias a inter-relação entre a cirurgia periodontal e a terapiaendodôntica convencional.

Estudio piloto de microfiltración in vitro de dos materiales selladores para blanqueamiento en dientes no vitales / Microfiltration on two sealing materials used for non vital teeth withening

El Blanqueamiento Dental Interno es un procedimiento que busca mejorar la estética del paciente al aclarar el esmalte de dientes que presenten una cantidad considerable de pigmentos debidos a diversas causas tanto intrínsecas como extrínsecas. La reabsorción cervical externa es una de las desventajas del procedimiento utilizado para hacer más claro el esmalte dental y su mayor factor desencadenante son las acciones química y física de los materiales utilizados durante el procedimiento. Este estudio piloto y experimental tuvo como objetivo observar una posible vía de comunicación entre la cámara pulpar y la raíz dental y se realizó midiendo la microfiltración del agente blanqueador ocurrida a través de dos materiales selladores del tratamiento de conductos. Se realizó un procedimiento endodóntico convencional y estandarizado a 16 premolares uniradiculares, los cuales fueron divididos en 3 grupos experimentales; Grupo I: 4 dientes control (2 sellados con resina fluida y 2 con un ionómero de vidrio) Grupo II: 6 dientes sellados inmediatamente después de la endodoncia (3 sellados con resina fluida y 3 con un ionómero de vidrio), Grupo III: 6 dientes sellados una semana después de la endodoncia (3 sellados con resina fluida y 3 con un ionómero de vidrio). A los Grupos II y III se les realizó un procedimiento de blanqueamiento interno con Perborato de Sodio y Peróxido de Hidrógeno al 30, al cabo del mismo, todos los dientes fueron teñidos con Azul de Metileno, inmersos en resina epóxica, cortados longitudinalmente con un micrótomo para, finalmente, analizar la mitad más conveniente en un microscopio estereoscópico. Se encontró que a través de todos los dientes hubo microfiltración del agente blanqueador hacia la raíz, excepto en un diente que fue sellado con ionómero pero ocho días después de terminada la endodoncia.

Internal dental whitening is a procedure to improve patient´s aestethetic through removal of crown surface stains. External cervical resorption is one of the main disadventages and consequence of dental withening. This pilot study looked for a possible communication between the pulpar camera and the root surface by measuring microfiltration of the bleaching agent among two endodontic sealing materials.16 single rooted premolars were studied using standard and conventional endodontic treatment. There was tree experimental groups. Group 1 was a 4 teeth sealed 2 with glass ionomer and the rest (2 teeth) with fluid resin. Group 2 contained 6 teeth sealed inmediately after endodontic treatment, 3 with fluid resin and the rest with galls ionomer. Group 3 was composed by 6 teeth sealed one week after endodontic treatment sealed 3 with fluid resin ans another 3 with glass ionomer. Teeth groups 2 and 3 were exposed to internal bleaching with sodium perborate and 30 hydrogen peroxide all teeth specimens were stained with methylene blue and after embebed under epoxic resin and cotted with microtome and analised under the stereoscophic microscope. The conclusion, all teeth showed dye percolation of the bleachy agent towards the root, with one tooth exception sealend with glass ionomer belong to the group in wich the procedure was performed one week after endodontic treatment.
