ABSTRACT

Biomaterial de tercera generación con una tasa de degradabilidad en la zona perirradicular y del foramen apical, con una velocidad similar a la que emplea el organismo para formar tejido calcificado y sellar biológicamente el extremo apical del diente. Mediante el recurso tecnológico de la microencapsulación se produce la liberación lenta y controlada de Ca2+ retenido en la superficie y en el interior de las microesferas de alginato de calcio, sin que se modifique de manera significativa las propiedades reológicas básicas del biomaterial de obturación de conductos, tales como la compresibilidad, plasticidad, extensibilidad, fluidez, viscosidad cinemática, viscosidad de compresión y endurecimiento por trabajo (AU)


Third-generation biomaterial with a degradability rate in the periradicular area and the apical foramen, with a speed similar to that used by the body to form calcified tissue and biologically seal the apical end of the tooth. Through the technological resource of microencapsulation, the slow and controlled release of Ca2+ retained on the surface and inside the calcium alginate microspheres is produced, without significantly modifying the basic rheological properties of the duct sealing biomaterial, such as compressibility, plasticity, extensibility, flowability, kinematic viscosity, compression viscosity, and work hardening (AU)

ABSTRACT

Se analizan aspectos fármaco-tecnológicos y clínicos de biocerámicos bioabsorbibles compuestos por biovidrios con capacidad osteogénica y microbicida, para ser utilizados como relleno bioactivo en el conducto radicular y como tratamiento terapéutico en el sitio de a lesión apicoperirradicular de origen endodóntico. Mediante un diagrama ternario se consideraron las diversas variables cuyos valores determinan las diferentes fases de los vidrios bioactivos, hasta alcanzar la formación de hidroxiapatita, cuando se someten a un medio biológico. Se analizaron composición y mecanismo de acción en la reparación posendodóntica, que parte de la integración del biomaterial al tejido duro sano, sin formación de fibrosis o proceso inflamatorio inmune (AU)


Pharmacotechnological and clinical aspects of bioabsorbable bioceramics composed of bioglasses with osteogenic and microbicidal capacity are analyzed, to be used as a bioactive filler in the root canal and as a therapeutic treatment at the site of an apicoperiradicular lesion of endodontic origin. By means of a ternary diagram, the various variables whose values determine the different phases of the bioactive glasses were considered, until reaching the formation of hydroxyapatite, when subjected to a biological medium. Composition and mechanism of action were analyzed in post-endodontic repair, which starts from the integration of the biomaterial into healthy hard tissue, without the formation of fibrosis or an immune inflammatory process (AU)

ABSTRACT

En la actualidad existe un nuevo paradigma en el tratamiento de piezas dentales con grandes lesiones periapicales. Ello tiene como principal propósito la conservación de dichas piezas, la regeneración de su sistema de inserción y hueso alveolar. Todo esto es posible gracias a la innovación científico-tecnológica que plantea como alternativa, la utilización de una terapéutica dinámica, mínimamente invasiva intralesional, destinada a erradicar los microorganismos que conforman el biofilm periapical e inducir la capacidad autorreparativa del sistema inmune mediante el uso de un biomaterial de tercera generación (Licon-D) (AU)


Currently there is a new paradigm in the treatment of dental pieces with large periapical lesions. The main purpose is the conservation of these pieces, the regeneration of their insertion system and alveolar bone. All this is possible thanks to the scientific and technological innovation that poses as an alternative, the use of a dynamic, minimally invasive intralesional therapy, designed to eradicate the microorganisms that make up the periapical biofilm and induce the autoreparative capacity of the immune system through the use of a third generation biomaterial (Licon-D) (AU)

ABSTRACT

Chronic pulpal inflammation and infection are the main predisposing factors for internal and external root resorption (IRR & ERR); however, merging of IRR and ERR is a rare lesion which rigorously alters the anatomy of root canals. this study reports a case of merged IRR and ERR in an asymptomatic maxillary left central incisor in a 33-year old caucasian woman that was managed by one-visit root canal therapy (RCT) using calcium-enriched mixture (CEM) cement. radiographic examination showed a short root with under-filled root canal obturation associated with ERR/IRR and an apical lesion. after thorough chemo-mechanical preparation, the root canal was obturated with CEM cement; one week later, the access cavity was permanently restored. clinical/radiographic examinations at 1-year follow-up revealed uneventful healing, reestablishment of lamina dura and stabilization of the resorptive defects. the treatment outcome demonstrates that one-visit RCT using CEM cement may be a viable treatment option in cases with merged external/internal root resorption. further clinical trials with a larger number of cases are suggested to document a higher level of evidence.

ABSTRACT

Introducción: el accidente con hipoclorito de sodio es una de las complicaciones que pueden presentarse durante la terapia endodóntica convencional. Constituye el sobrepaso del irrigante a los tejidos periapicales ya sea durante la irrigación de los conductos radiculares o por medio de la inyección accidental en los tejidos blandos. Produce al paciente una sintomatología dolorosa inmediata, con una respuesta inmunológica exacerbada y necrosis hística. Objetivo: determinar las posibles causas del accidente con hipoclorito de sodio y exponer el protocolo de manejo clínico y farmacológico establecido para esta eventualidad. Caso clínico: se informa el caso de un sobrepaso accidental de hipoclorito de sodio hacia el periápice en la raíz distovestibular del diente 17 en un paciente de 67 años de edad, con hipertensión arterial controlada, diagnóstico de pulpa sana y requerimiento de realización de endodoncia preprotésica. Se exponen la toma de medidas clínicas y farmacológicas posterior al accidente con hipoclorito de sodio, así como el suministro de corticoterapia inmediata, analgesia, manejo del dolor por bloqueo anestésico del área comprometida y para disolución del hipoclorito de sodio, para completar el esquema de manejo medicación antibiótica profiláctica. Conclusiones: los factores predisponentes para la generación de un accidente con hipoclorito son: enfermedades que causen resorción periapical, selección inadecuada del tipo de jeringa y aguja con la que se realiza la irrigación y la no determinación adecuada de la longitud radicular. El manejo de estos accidentes con corticoides y analgesia reduce la agresividad de la sintomatología presentada por el paciente, así como la profilaxis antibiótica, disminuye el riesgo de daño hístico(AU)


Introduction: sodium hypochlorite accidents are one of the complications that may arise during conventional endodontic therapy. In hypochlorite accidents, the irrigant flows into the periapical tissue either during irrigation of root canals or by accidental injection into soft tissue. This situation causes immediate pain symptoms in the patient, with an exacerbated immune response and tissue necrosis. Objective: determine the possible causes of sodium hypochlorite accidents and present the clinical and pharmacological management protocol established for these events. Clinical case: a case is reported of accidental flowing of sodium hypochlorite to the apex of the distovestibular root of tooth 17 in a 67-year-old male patient with controlled hypertension and a diagnosis of healthy pulp requiring preprosthetic endodontic therapy. A description is provided of the clinical and pharmacological actions taken after the sodium hypochlorite accident, as well as the immediate application of corticotherapy, analgesia, pain management by anesthetic block of the compromised area and for dissolution of the sodium hypochlorite, to complete the management scheme with prophylactic antibiotic medication. Conclusions: the following are predisposing factors for the occurrence of a hypochlorite accident: conditions that cause periapical resorption, inadequate choice of the type of syringe and needle to perform the irrigation, and incorrect determination of the root length. Management of these accidents with corticosteroids and analgesia reduces the aggressiveness of symptoms, whereas antibiotic prophylaxis lessens the risk of tissue damage(AU)

ABSTRACT

Muitos profissionais ficam confusos quando um dente tem lesão periapical e mantém a vitalidade pulpar. Muitas lesões imitam imagiologicamente as lesões periapicais crônicas inflamatórias e os dentes permanecem com vitalidade pulpar. Sempre devemos lembrar que: 1) dentes com vitalidade pulpar não devem ser abertos sem um diagnóstico prévio das lesões que são portadores; tratamento endodôntico não deve ser aplicado como meio de diagnóstico ou teste terapêutico de lesões periapicais em dentes com vitalidade pulpar. 2) Realizar tratamentos endodônticos em dentes com vitalidade pulpar e com lesões que imitam periapicopatias pode prolongar o tempo de uma abordagem adequada e piorar em muito o prognóstico da lesão. 3) Em dentes com vitalidade pulpar e lesões periapicais de origem a determinar, é muito importante a inter-relação clínica, imagiológica e microscópica para a troca de experiências e conhecimento, visando um diagnóstico seguro e terapêutica eficaz. 4) As lesões relacionadas devem ser mentalizadas ou anotadas para que se aplique sempre frente a dentes com lesões periapicais e com vitalidade pulpar!

ABSTRACT

Esta Tese reporta dois estudos distintos relacionados à terapia de manutenção periodontal (TMP): achados microbiológicos longitudinais de 6 anos relacionados à cooperação dos indivíduos e efeito do tabagismo na perda dental. A justificativa para estes estudos é baseada em dois aspectos pontuais: (1) Embora a associação do tabagismo como fator de risco para a periodontite e pior resposta à TMP tenha sido demonstrada em muitos estudos, o efeito isolado deste sobre a perda dental em indivíduos submetidos a TMP ainda não foi reportado em revisões sistemáticas; (2) Poucos estudos têm sido conduzidos avaliando mudanças longitudinais na microbiota subgengival de indivíduos em TMP e, até o momento, nenhum estudo relacionou níveis de bactérias associadas à periodontite com o grau de cooperação dos indivíduos em TMP. Neste sentido, os objetivos deste estudo são apresentados em dois artigos científicos: (1) realizar uma revisão sistemática e meta-análise do efeito do tabagismo na perda dental em indivíduos em TMP, com a seguinte questão focal: ¿Qual é o efeito do tabagismo na perda dental em indivíduos em terapia de manutenção periodontal?¿; (2) avaliar longitudinalmente, durante 6 anos, o efeito da cooperação em TMP na frequência das bactérias Actinomyces naeslundii, Porphyromonas gingivalis, Tanerella forsythia e Treponema dentícola. Na revisão sistemática as bases de dados MEDLINE, WEB OF SCIENCE, COCHRANE LIBRARY e SCOPUS foram pesquisadas, incluindo artigos até fevereiro de 2017. A estratégia de busca identificou 728 referências. Após a remoção das duplicatas, restaram 591 para a seleção baseada nos títulos e resumos, e desses, foram selecionados 36 para leitura completa do texto. Após a leitura, foram incluídos 10 artigos para revisão sistemática e 3 artigos para meta-análise. A qualidade da evidência científica foi moderada para indivíduos tabagistas em TMP apresentarem maior chance de perda dental que indivíduos não tabagistas. A metodologia do estudo microbiológico englobou um total de 56 indivíduos, todos recrutados de um coorte prospectivo com 212 participantes de um programa de TMP. Estes indivíduos foram acompanhados durante 6 anos, em 5 tempos de avaliações: T1 (anterior à terapia periodontal ativa), T2 (após a terapia periodontal ativa), T3 (última visita à TMP em 2 anos), T4 (última visita à TMP em 4 anos) e T5 (última visita à TMP em 6 anos). Assim, 28 indivíduos cooperadores regulares (CR) foram randomizados e pareados, pelo gênero e idade, a 28 indivíduos cooperadores irregulares (CI). Durante a TMP, os exames periodontais avaliaram os parâmetros clínicos: índice de placa (IP), profundidade de sondagem (PS), nível clínico de inserção (NCI) e sangramento à sondagem (SS). A quantificação de bactérias em carga total e dos níveis de A. naeslundii, P. gingivalis, T. forsythia e T. dentícola foi executada pela reação em cadeia da polimerase quantitativa (qPCR). Este estudo concluiu que CI apresentaram piores parâmetros clínicos periodontais e maiores níveis de carga bacteriana total que CR, refletindo o papel benéfico da cooperação na TMP em manter a estabilidade da condição periodontal


This Thesis report two distinct issues related to periodontal maintenance therapy (PMT): microbiological findings of 6 years related to compliance of individuas and effect of smoking on tooth loss. The rattionale for these studies is based on two specific aspects: (1) Although the association of smoking as a risk factor for periodontitis and worse response to PMT has been demonstrated in many studies, the isolated effect of smoking on tooth loss in patients undergiong PMT has not been reported in systematic reviews; (2) Few studies have been conducted on longitudinal changes in the subgingival microbiota of individuals in PMT and to date, no study related levels of bacteria to the degree of cooperation of individuls in PMT...

ABSTRACT

Abstract Great attention has been given to the study of radiolucent periapical lesions to avert possible misdiagnosis of apical periodontitis associated with certain radiolucent non-endodontic lesions. However, there are a significant number of radiopaque lesions found in the periapical region, which could be equally relevant to endodontic practice. The diagnosis and management of these radiopaque/hyperdense lesions could be challenging to the endodontist. These bone alterations could be neoplastic, dysplastic or of metabolic origin. In the context of the more widespread use of cone-beam CT, a detailed review of radiopaque inflammatory and non-inflammatory lesions is timely and may aid clinicians perform a differential diagnosis of these lesions. Distinguishing between inflammatory and non-inflammatory lesions simplifies diagnosis and consequently aids in choosing the correct therapeutic regimen. This review discusses the literature regarding the clinical, radiographic, histological and management aspects of radiopaque/hyperdense lesions, and illustrates the differential diagnoses of these lesions.

ABSTRACT

Often there is the need of moving teeth endodontically treated or teeth still in endodontic treatment. In order to collaborate with the comprehension and substantiation of the following subjects will be discussed: 1) Orthodontic movement in endodontically treated teeth without periapical lesion, 2) Orthodontic movement in endodontically treated teeth with inflammatory periapical lesion, and 3) Orthodontic movement in teeth endodontically treated due to aseptic pulp necrosis by dental trauma. In practically all situations, endodontically treated teeth to be orthodontically moved must be subjected to a careful evaluation by the endodontist about the conditions, adequate or not, of the endodontic treatment. Then, in this paper it was sought to induce an insight for new clinical researches about the theme that may definitely prove the information obtained by interrelations of information in parallel to clinical practice.


Com frequência, há a necessidade de movimentar-se dentes endodonticamente tratados ou ainda em tratamento endodôntico. Para colaborar com a compreensão e fundamentação do assunto, abordaremos: 1) a movimentação ortodôntica em dentes endodonticamente tratados sem lesão periapical; 2) a movimentação ortodôntica em dentes endodonticamente tratados com lesão periapical inflamatória; e 3) a movimentação ortodôntica em dentes endodonticamente tratados de necrose pulpar asséptica por traumatismo dentário. Em praticamente todas as situações, dentes endodonticamente tratados a serem movimentados ortodonticamente devem ser submetidos a uma avaliação criteriosa, por parte do endodontista, sobre as condições adequadas ou não do tratamento endodôntico. Em seguida, no presente trabalho procurou-se, singelamente, induzir um insight para novas pesquisas clínicas sobre o tema, que possam definitivamente comprovar os conhecimentos obtidos pela inter-relação de conhecimentos em paralelo à prática clínica.

ABSTRACT

Objetivo: luego de la extirpación de la pulpa, el procedimiento de regeneración pulpar, inducido por un coágulo sanguíneo apical dentro de los conductos radicualres con ápices incompletamente formados, ha sido experimentado. El objetivo de este estudio piloto fue investigar si este mismo proceso se produce al utilizar el conducto distal del primer molar inferior de la rata como modelo experimental. Materiales y métodos: se realizaron biopulpectomías totales en el conducto distal del primer molar inferior derecho en diez ratas Wistar macho que presentaban sus ápices incompletamente calcificados. El primer molar inferior izquierdo no fue intervenido y se utilizó como control negativo. Se provocó una hemorragia apical con el objeto de inducir la formación de un coágulo sanguíneo. El acceso coronario se obturó con resina compuesta y se obtuvieron radiografías posoperatorias inmediatas. Las mandíbulas fueron resecadas y posteriormente radiografiadas. Los primeros molares, junto con las estructuras periodontales y óseas que los rodean, fueron removidos, fijados y procesados para estudio histológico. A las 96 horas, los ápices de los dientes experimentales permanecían aún incompletamente calcificados y se observó dentro de los conductos la invaginación de un tejido de aspecto similar al periodontal, muy celular y con gran cantidad de vasos sanguíneos. Los controles revelaron un desarrollo radicular más extenso, donde se podía apreciar la presencia de la pulpa, la papila dental y numerosos odontoblastos jóvenes. A los treinta días, se observó en los dientes experimentales un desarrollo radicular casi completo y que el conducto se encontraba ocupado por tejido fibroso maduro con vasos sanguíneos. Los dientes de control presentaron un desarrollo radicular completo, con tejido pulpar normal muy vascularizado y paredes dentinarias más espesas. Conclusión: los resultados sugieren que el primer molar inferior de la rata podría constituir un modelo adecuado.

ABSTRACT

OBJECTIVE: The presence of periapical radiolucency has been used as a criterion for endodontic treatment failure. However, in addition to the inherent limitations of radiographic examinations, radiographic interpretations are extremely subjective. Thus, this study investigated the effect of partial analysis of root filling quality and periapical status on retreatment decisions by general dentists. MATERIAL AND METHODS: Twelve digitalized periapical radiographs were analyzed by 10 observers. The study was conducted at three time points at 1-week intervals. Radiographs edited with the Adobe Photoshop CS4 software were analyzed at three time points: first, only root filling quality was analyzed; second, only the periapical areas of the teeth under study were visualized; finally, observers analyzed the unedited radiographic image. Spearman ’s coefficient was used to analyze the correlations between the scores assigned when the periapical area was not visible and when the unedited radiograph was analyzed, as well as between the scores assigned when root fillings where not visible and when the unedited radiograph was analyzed. Sensitivity, specificity, positive and negative predictive values between partial images and unedited radiographs were also used to analyze retreatment decisions. The level of significance was set at 5%. RESULTS: The visualization of the root filling on the unedited radiograph affected the interpretation of the periapical status and the technical quality of the fillings has a greater influence on the general dentist’s decision to prescribe endodontic retreatment than the periapical condition. CONCLUSION: In order to make endodontic diagnosis, radiographic interpretation process should not only emphasize technical aspects, but also consider biological factors.

ABSTRACT

La reparación postendodóntica es una respuesta muy compleja que requiere para su comprensión y análisis, un minucioso diagnóstico clínico-radiológico, un detallado conocimiento de su fisiopatología y unpreciso estudio de las posibles interacciones actuantes en el sistema endodóntico bacteriano. El comportamiento y las estructuras de las lesiones a tratar, responden a funciones generadas por mecanismos a nivel de la biología molecular, para lograr la reparación por regeneración de los tejidos que la componen. Contamos para ello con biomateriales de tercera generación, cuyo objetivo es estimular a nivel molecular la proliferación y diferenciación celular y dirigir la producción y organización de la matriz extracelular

ABSTRACT

Se realizó un estudio experimental, prospectivo y de control en un grupo de pacientes de ambos sexos, mayores de 15 años con procesos crónicos periapicales, que fueron atendidos en el departamento de Endodoncia de la Clínica Estomatológica Docente Severino Rossel González del municipio Artemisa, en el período comprendido desde junio de 2010 hasta junio de 2011 que constituyó el universo del estudio, con el objetivo de evaluar la aplicación de la laserterapia en la reparación ósea periapical, tomándose una muestra no probabilística de sujetos voluntarios de 50 pacientes, de los cuales se tomó un grupo de control al que se le realizó el tratamiento de endodoncia convencional y otro grupo experimento, al que además de la endodoncia se le aplicaron 10 sesiones de laserterapia. La información fue procesada en el software estadístico SPSS 11,5, utilizando como medida el porcentaje, la prueba de Chi cuadrado. Los pacientes fueron examinados a los tres y seis meses, y al año de haber recibido el tratamiento se evaluó el grado de reparación ósea y tamaño de la lesión en ambos grupos constatando de que a pesar de que existía independencia entre las variables analizadas en el grupo que se empleo la laserterapia se obtuvo una más rápida regeneración ósea periapical; las lesiones pequeñas y moderadas se regeneraron totalmente en su gran mayoría en ambos grupos. Se concluye que la laserterapia resultó ser más efectiva que el proceder acostumbrado y no desencadenó reacciones adversas en ninguno de los casos


It was carried out an experimental, prospective and control study in a group of patients of both sexes, older than 15 years with chronic periapical processes that were assisted at the Endodontics Department of Severino Rossel González Teaching Stomatologic Clinic of Artemisa municipality, in the period from June 2010 to June 2011 which constituted the universe of the study, with the aim of evaluating the application of laser therapy in periapical bone repair, it was taken a non probabilistic sample of volunteer subjects of 50 patients, out of whom it was taken a control group that underwent conventional endodontic treatment and another experiment group to which in addition to endodontics, it was applied 10 sessions of laser therapy. The information was processed using SPSS 11,5 statistical software, using percentage as measurement the Chi-squared test. Patients were examined at three and six months, and one year after receiving the treatment it was assessed the degree of bone repair and lesion size in both groups noting that although there was independence between the variables analyzed in the group in which was used the laser therapy, a faster bone periapical regeneration was obtained; small to moderate lesions fully regenerated mostly in both groups. Concluding that laser therapy was more effective than the usual procedure and did not trigger adverse reactions in any of the cases

ABSTRACT

El dolor postoperatorio después del tratamiento de conductos de una sola sesión es una complicación conocida por el clínico. El propósito de este trabajo fue revisar los resultados de investigaciones previas sobre la prevalencia del dolor postoperatorio después de un tratamiento de conductos en una cita. Esta revisión pretende proporcionar apoyo al clínico para la toma de decisiones durante el tratamiento de los dientes con pulpas vitales o necróticas, en forma manual o mecánica, mediante instrumentos rotatorios.

ABSTRACT

A 24-year-old female patient reported with a mutilated maxillary left central incisor. The coronal tooth structure remaining was very less, discolored, and brittle. She gave history of trauma about 15 years back when the tooth got fractured. An intraoral periapical radiograph revealed an open apex and a large periapical lesion. The case was managed successfully by conservative means using intracanal calcium hydroxide and mineral trioxide aggregate (MTA) apical barrier followed by a fiber post and a core. The final crown restored back esthetics and function. A 6-month follow-up demonstrated a clinically asymptomatic and adequately functional tooth, with radiological signs of healing.
