ABSTRACT

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)

ABSTRACT

ABSTRACT Objective: To determine the awareness and sources of information on first aid management of avulsed permanent teeth in a group of South-western Nigerian mothers. Material and Methods: An 18-item interviewer-administered questionnaire was used to survey 385 mothers attending the antenatal and immunization clinics on their perception towards dental avulsion, its management, sources, and preferred mode of receiving information on first aid. The effect of all significant factors was inferred at p<0.05. Results: Mothers who had previous information on the first aid management of dental avulsion had significantly higher knowledge (p=0.000). Majority (80.8%) of the mothers did not know that an avulsed permanent tooth could be replanted, though mothers whose children had not experienced dental trauma had significantly higher knowledge (p=0.003). The knowledge of first aid management of avulsed permanent tooth was low, regardless of age, education and employment status of the respondents. Conclusion: There was low knowledge among mothers regarding the first aid measures in the management of avulsed permanent teeth. Their main preference for receiving information was through social media and television. There is a need to increase oral health educational campaigns targeted towards mothers.

ABSTRACT

Objective: To compare the accuracy of digital radiography and CBCT for the diagnosis of vertical root fractures in single root teeth. Material and Methods: For this descriptive-analytic study, 50 non-fractured, single-root teeth were selected. The teeth were randomly divided into a control and an experimental group (25 teeth in each group). The teeth in the control group did not have vertical root fractures. In the test group, after preparing the access cavity, the root canal was cleared and loosened up to No. 80 file, then a vertical root fracture was created by one of the K-Reamers Nos. 90- 130.The images were prepared by CBCT radiography in axial and cross-sectional slices and in digital radiography with PSP sensors at mesial, distal, and parallel angles. The Chi-square test was used to express the correlation of variables. Results: In the diagnosis of vertical root fractures, the sensitivity of CBCT in the axial section was 32% and in the cross-sectional slice it was 20%, whereas the specificity in both the sections was 100%. The sensitivity of the digital radiography in detecting vertical root fractures for parallel, mesial, and distal angles was 38%, 16%, and 24%, respectively. Conclusion: According to this study, the sensitivity, specificity, and accuracy of digital radiography and CBCT were not significantly different.

ABSTRACT

ABSTRACT: The aim of this study was to carry out a retrospective study of cases seen at the Child and Adult Dental Traumatology Clinic, Faculty of Dentistry, Universidad de Chile, Santiago. A retrospective study was carried out analysing the records of patients seen at the Dental Traumatology Clinic, Faculty of Dentistry, Universidad de Chile from January 2012 to March 2017. The inclusion criteria was that patient complaint was due to dental trauma. Data were tabulated indicating age and sex of the patient, cause, day, and tooth involved and the initial diagnosis of the dental trauma. Chi-square, Shapiro Wilk normality test and Mann-Whitney test were used for frequency analyses. A total of 117 dental records were analysed, 90 of these met the inclusion criteria. The age range of the sample was 5 to 60 years, and the average age was 14.3 years. Most injuries occurred in patients during the first and second decades of their life. Of the patients, 59.3 % were men and 40.7 % were women. The most frequent dental traumas were complicated and uncomplicated crown fractures, followed by root fractures. In the majority of the cases analysed, only one tooth was affected, and the tooth most frequently traumatized was the right upper central incisor, followed by the left upper central incisor. The most frequent dental trauma of the cases treated at the Child and Adult Dental Traumatology Clinic, Faculty of Dentistry, Universidad de Chile, Santiago, between 2012 and 2017 were crown fractures.

ABSTRACT

Objective: To evaluate the fracture resistance of endodontically treated teeth restored with different types of intracanal posts. Material and Methods: Sixty human upper central incisors (n = 60) were divided according to the performance of different protocols for restoration with intracanal posts. Groups without endodontic treatment (NT) and with endodontic treatment (TR) without placement of intracanal posts, served as controls. The experimental groups received endodontic treatment and were restored with: fiberglass post with composite resin filling core (PFV-NP); carbon fiber post with composite resin filling core (PFC-NP); nickel-chromium metal cast and core posts (NiCr); or copper-aluminum metal cast and core posts (CuAl). The specimens were then tested to determine the maximum fracture resistance and the failure types of fracture (infra-crestal and supra-crestal). Data were analyzed by one-way ANOVA and Tukey test (α<0.05). Results: Increased fracture resistance was observed for NT group (p<0.05). Within endodontically treated teeth groups, NiCr showed higher resistance to fracture, differing statistically from groups FV+NP and FC+NP (p<0.05). Higher frequency of infra-crestal fractures was observed in NT and TR groups. Conclusion: The installation of nickel-chromium intracanal cast and core posts contributed to higher fracture resistance and lower risk of fractures difficult to repair.

ABSTRACT

El efecto Doppler es la base científica de la flujometría láser Doppler. El efecto fue descrito por primera vez en el año de 1842 por el físico austriaco Christian Doppler en su tratado Über das farbige licht der doppelsterne und einige andere gestirne des himmels (Sobre el color de la luz en estrellas binarias y otros astros). Este principio ha permitido desarrollar técnicas y aparatos que han sido empleados en el ramo médico para medir la perfusión en diversos órganos y tejidos del cuerpo, y que han sido útiles como método diagnóstico. En la odontología, poco a poco comienza a reportarse información acerca del uso del Doppler en las diversas estructuras bucodentales, y ha demostrado ser no invasivo y de gran utilidad diagnóstica. Son pocos los estudios reportados en la rama de la odontología en cuanto a esta nueva tecnología; es importante comenzar líneas de investigación apoyadas en ella para beneficio de los pacientes.


The Doppler eff ect, the scientifi c basis of laser Doppler fl owmetry, wasfi rst described in 1842 by Austrian physicist Christian Doppler in histreatise Über das farbige Licht der doppelsterne und einige andere gestirnedes Himmels (On the Colored Light of the Binary Stars and SomeOther Stars of the Heavens). This principle has led to the developmentof techniques and devices that have been used in the fi eld of medicineto measure perfusion in various organs and tissues, and have provideda useful method of diagnosis. In dentistry, information on the use ofthis method in the various structures of the mouth has slowly begunto be published. As a result, the need for its continued use in the fi eldof oral health has become evident, given that it has proven to be noninvasiveand extremely useful in diagnosis. It is a diagnostic technique that is commonly used in healthcare and has been widely developedin the fi eld of medicine, yet there have been few reported studies of it suse in dentistry, which is an important step towards opening new linesof research based on this new technology for the benefi t of patients.

ABSTRACT

El propósito de este reporte es presentar el caso de un paciente femenino con presencia de fractura radicular vertical (FRV) de un segundopremolar superior izquierdo, remitida a la clínica de Postgrado de Endodonciade la Universidad De La Salle Bajío para remoción de poste y retratamiento dental. Una vez realizado el diagnóstico se determinó FRV mediante sondeo minucioso irregular en un solo punto con sonda flexible, ligero dolor a la masticación y pérdida ósea radiográfica en forma de halo o gota, se sugirió como tratamiento extracción dental y cirugía exploratoria a petición del paciente


The aim of this report is to present the case of a female patient with a vertical root fracture (VRF) of a maxillary second premolar who was referred to the Postgraduate Endodontic Clinic of De La Salle Bajío University in León, Guanajuato, Mexico for the removal of a metallic post and retreatment of root canals. Examination via thorough irregular periodontal probing at a single point with a fl exible probe resulted in a diagnosis of VRF, slight pain on chewing, and radiographic bone loss in the shape of a halo or droplet, for which the suggested treatment was the extraction of the tooth, a surgical procedure that was subsequently performed at the patient’s request.

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

Objetivo: presentar la resolución clínica de una fractura dentaria incompleta mediante la realización de una restauración adherida de tipo onlay. Caso clínico: un paciente de 36 años de edad consultó por dolor al masticar enl a pieza 3.7, la cual presentaba una restauración plástica oclusal. Al removerla, se observó una fractura en dirección mesiodistal, sin movilidad de ambos cabos de fractura, por lo que se realizó una incrustación adherida de tipo onlay. Conclusión: el correcto diagnóstico de una fractura dentaria incompleta y la comprensión de su etiología son fundamentales para la elección de un tratamiento conservador y con un alto grado de predictibilidad, como lo son las restauraciones adheridas tipo onlay.

ABSTRACT

Introdução: radiografias intrabucais são uma importante ajuda investigativa na detecção de alterações na raiz dentária, incluindo fraturas radiculares verticais (FRV). Objetivo: avaliar a capacidade de radiografias convencionais e digitais, ortogonais e dissociadas para detectar FRV em dentes que apresentam diferentes condições do canal radicular. Métodos: sessenta dentes foram divididos em três grupos, considerando-se a condição do canal (não obturado, obturado com guta-percha e obturado com guta-percha e pino metálico). Em cada grupo, dez dentes foram artificialmente fraturados e dez dentes (controles), não foram fraturados. Realizaram-se radiografias convencionais (Kodak), e digitais (placas de fósforo – VistaScan Durr Dental), ortogonais e horizontalmente dissociadas. Usando um teste cego, três observadores calibrados realizaram avaliações em quatro tempos distintos. Valores modais foram utilizados para calcular a sensibilidade, especificidade e acurácia. A área sob a curva ROC (aucROC), e intervalos de confiança (IC ), foram usados para comparar o desempenho entre os sistemas radiográficos, bem como a influência de imagens ortogonais e combinadas (ortogonal mais dissociadas). Resultados: radiografias combinadas (ortogonal + dissociadas), apresentaram maior aucROC para ambas as imagens convencionais e digitais. Os ICs mostraram diferenças estatisticamente significativas entre as radiografias convencionais ortogonais e digitais combinadas (IC: 0,403-0,697 e 0,767-0,967, respectivamente). Além disso, quando apenas incidências ortogonais foram consideradas, radiografias digitais proporcionaram melhores resultados do que as convencionais (IC: 0,622-0,878 e 0,403-0,697, respectivamente). Conclusão: a forte tendência de melhores resultados dos testes de diagnóstico proporcionados pelas radiografias digitais sugere que o sistema digital, utilizando projeções combinadas, é mais apropriado para investigar FRV do que o convencional

ABSTRACT

Fraturas em dentes anteriores superiores são comuns, especialmente nos incisivos centrais. Quando o fragmento dentário fraturado está presente ou não perdeu suas propriedades ópticas, pode e deve ser utilizada a técnica de colagem de fragmento. Atualmente, a técnica de colagem de fragmentos, além de ser uma forma conservadora para restabelecer a estética e função de dentes anteriores fraturados, permite a restauração da estrutura dentária com resultados ópticos excelentes e previsibilidade. Assim, o conhecimento da técnica de colagem de fragmento e dos materiais que podem ser empregados são fundamentais. Dessa forma, o objetivo do presente trabalho é apresentar, por meio de casos clínicos, a técnica de colagem de fragmento para restauração em dentes anteriores fraturados.


Fracture of anterior teeth is common especially on maxillary central incisors. When the fractured fragment is present or did not lose its optical properties, the reattachment should be indicated. Nowadays the technique for fragment reattachment besides being more conservative allows the restoration of the dental structure with excellent optical results and good long-term stability. Moreover the knowledge of fragment reattachment technique and dental materials employed plays an important role. Thus, it is the aim of the present work to demonstrate the technique for fragment reattachment in anterior fractured teeth.

ABSTRACT

O objetivo desta revisão de literatura foi analisar os principais fatores relacionados às propriedades físicas e mecânicas dos pinos resinosos reforçados por fibras, os quais apresentam elevada influência na qualidade funcional das restaurações de dentes tratados endodonticamente. Esse sistema de pinos tem experimentado uma aceitação cada vez maior como opção restauradora, pois oferece um verdadeiro biomimetismo ao dente a ser restaurado, redução do tempo clínico para confecção do núcleo e melhor uniformidade na distribuição de forças ao longo do remanescente radicular, evitando fraturas irreversíveis. Com base na literatura consultada, conclui-se que os pinos fibrorresinosos são excelentes alternativas reconstrutoras aos núcleos metálicos fundidos, frente à semelhança de suas propriedades físicas e mecânicas com as da estrutura dental


The purpose of this review was to analyze the main factors related to physical and mechanical properties of fiber reinforced resin posts, which have strongly influence the quality of functional restoration of endodontically treated teeth. This post system has experienced a growing acceptance as a restorative option because it offers a true biomimetism to the tooth to be restored, a reduced time to prepare the core and a distribution more uniform of the forces along the remaining root, avoiding irreversible fractures. Based on the literature, we concluded that the fiber reinforced resin posts are excellent alternatives to metal casting cores, when compared to their similar physical and mechanical properties with those of tooth structure

ABSTRACT

A retrospective survey was designed to identify diagnostic subgroups and clinical factors associated with odontogenic pain and discomfort in dental urgency patients. A consecutive sample of 1,765 patients seeking treatment for dental pain at the Urgency Service of the Dental School of the Federal University of Goiás, Brazil, was selected. Inclusion criteria were pulpal or periapical pain that occurred before dental treatment (minimum 6 months after the last dental appointment), and the exclusion criteria were teeth with odontogenic developmental anomalies and missing information or incomplete records. Clinical and radiographic examinations were performed to assess clinical presentation of pain complaints including origin, duration, frequency and location of pain, palpation, percussion and vitality tests, radiographic features, endodontic diagnosis and characteristics of teeth. Chi-square test and multiple logistic regression were used to analyze association between pulpal and periapical pain and independent variables. The most frequent endodontic diagnosis of pulpal pain were symptomatic pulpitis (28.3 percent) and hyperreactive pulpalgia (14.4 percent), and the most frequent periapical pain was symptomatic apical periodontitis of infectious origin (26.4 percent). Regression analysis revealed that closed pulp chamber and caries were highly associated with pulpal pain and, conversely, open pulp chamber was associated with periapical pain (p<0.001). Endodontic diagnosis and local factors associated with pulpal and periapical pain suggest that the important clinical factor of pulpal pain was closed pulp chamber and caries, and of periapical pain was open pulp chamber.


Um estudo retrospectivo foi realizado para identificar fatores clínicos e de diagnóstico associado com a dor de origem odontogênica. Foram selecionados 1765 pacientes que buscaram tratamento para dor odontogênica no Serviço de Urgência da Faculdade de Odontologia da Universidade Federal de Goiás. Os critérios de inclusão foram dor de origem pulpar ou periapical antes do tratamento dentário (mínimo de 6 meses depois da última consulta odontológica), e os critérios de exclusão foram dentes com anomalias de desenvolvimento e falta de informações ou registros incompletos. Avaliações clínicas e radiográficas foram realizadas para se obter as características clínicas de dor, incluindo origem, duração, frequência e localização da dor, testes de palpação, percussão e vitalidade pulpar, aspectos radiográficos, diagnóstico endodôntico e características dos dentes. Os testes qui-quadrado e regressão logística múltipla foram utilizados para verificar a associação entre a dor de origem pulpar e periapical e variáveis independentes. O diagnóstico endodôntico de dor de origem pulpar mais frequente foi pulpite sintomática (28,3 por cento) seguido por pulpalgia hiper-reativa (14,4 por cento), e o mais frequente de dor de origem periapical foi periodontite apical sintomática infecciosa (26,4 por cento). Análise de regressão revelou que câmaras pulpares fechadas e cáries estavam altamente associadas à dor pulpar e, inversamente, câmara pulpar aberta estava associada à dor periapical (p<0,001). O diagnóstico endodôntico e fatores locais associados com dor de origem pulpar e periapical sugerem que os fatores clínicos importantes das dores pulpares foram câmaras pulpares fechadas e cáries, e de dor periapical foi câmara pulpar aberta.

ABSTRACT

Fraturas coronárias de dentes anteriores são uma forma comum de traumatismo dentário que afeta principalmente crianças e adolescentes. A restauração adequada de dentes anteriores fraturados tem sido uma preocupação constante entre clínicos e especialistas, pois marca profundamente as pessoas envolvidas, independente da idade, do sexo e do nível socioeconômico do paciente. Uma das opções de manejo clínico das fraturas coronárias quando o fragmento do dente está disponível é a colagem do fragmento dental, que proporciona bons resultados e de longa duração estética (porque a forma original do dente, cor e textura de superfície são mantidos); também restaura a função, fornece uma resposta psicológica positiva, e é um procedimento relativamente simples. A cooperação do paciente e a compreensão das limitações do tratamento são de extrema importância para o bom prognóstico. O objetivo deste trabalho foi consultar a literatura pertinente à técnica de colagem de fragmento dental em dentes anteriores fraturados, resumindo os conhecimentos atuais, apresentando recomendações para os melhores resultados a serem obtidos com a técnica.


Coronary fractures of anterior teeth are a common form of dental trauma that mainly affects children and adolescents. The proper restoration of fractured anterior teeth has been a concern among practitioners and specialists, because it marks people deeply involved, regardless of age, sex and socioeconomic status of the patient. One of the options for clinical management of coronary fractures when the tooth fragment is available is the glue dental fragment. This procedure can give good results and long-lasting esthetics (because the original tooth shape, color and surface texture are maintained). It also restores function, provides a positive psychological response, and is a relatively simple procedure. Patient cooperation and understanding of the limitations of treatment is extremely important for good prognosis. The objective was to consult the relevant literature in the technique of bonding dental fragment in anterior teeth fractured, summarizing current knowledge; presenting recommendations for the best results are obtained with this technique.

ABSTRACT

Introdução: O presente estudo tem o objetivo de avaliar comparativamente in vitro a resistência à fratura radicular de dentes tratados endodonticamente, usando diferentes materiais obturadores: AH Plus (Dentsply/De Trey, Alemanha), Real Seal (Sybron Endo, EUA), GuttaFlow (Coltène/Whaledent, Suíça) , ActiV GP (Brasseler, EUA) e Thermafil (Dentsply-Tulsa Dental, EUA). Métodos: Sessenta e quatro pré-molares inferiores foram divididos em Grupo-controle (n=4), onde as raízes não foram nem instrumentadas nem obturadas e outros 5 grupos de acordo com os materiais obturadores empregados: Grupo AH Plus (n=12); Grupo Real Seal (n=12); Grupo GuttaFlow (n=12); Grupo ActiV GP (n=12); Grupo Thermafil (n=12). As raízes foram instrumentadas com o sistema Protaper Universal (Dentsply-Maillefer, Suíça), e em seguida foram obturadas com os respectivos materiais. Após a obturação, todos os espécimes foram armazenados a 37ºC com 100% de umidade por 72 horas e incluídos em resina acrílica. Os espécimes foram submetidos ao teste de resistência à fratura em uma máquina de ensaios triaxiais (1,0mm/min). Resultados: Os valores médios obtidos e o desvio-padrão (em Newtons) em ordem decrescente foram: Grupo-controle û 394,25 ± 56,17 N; Grupo ActiV GP û 263 ± 89,32 N; Grupo Thermafil û 198,17 ± 61,65 N; Grupo AH Plus û 158,08 ± 31,56 N; Grupo Real Seal û 154,92 ± 42,64 N e Grupo GuttaFlow û 107,92 ± 20,72 N. Os dados foram submetidos aos testes ANOVA e Dunett (5%). Conclusões: Dentre os grupos experimentais, as raízes obturadas com ActiV GP mostraram-se mais resistentesà força vertical aplicada, porém similares aos grupos controle e Thermafil. Os grupos AH Plus, RealSeal e Thermafil mostraram-se similares estatisticamente quanto à resistência à fratura. O grupo GuttaFlow apresentou menores valores médios de resistência à fratura.


Introduction: The aim of this study is to evaluate the in vitro vertical fracture resistance of endodonticallytreated teeth using different root filling materials: AH Plus (Dentsply/De Trey, Germany), Real Seal (SybronEndo, EUA), GuttaFlow (Coltène/Whaledent, Swiss) , ActiV GP (Brasseler, EUA) and Thermafil (Dentsply-Tulsa Dental, EUA). Methods: Sixty four single-rooted human lower premolar were assigned into a Control Group (n=4), where the roots were not prepared or filled, and five experimental groups (n=12) according to the root filling materials: Group AH Plus; Group Real Seal; Group GuttaFlow; Group ActiV GP; Group Thermafil. The roots were prepared using Protaper Universal system (Dentsply-Maillefer, Swiss) and filled with one of the root filling materials. Then, the specimens were stored at 37ºC at 100% humidity for 72 hours and included in acrylic resin. The specimens were submitted to a vertical fracture resistance using a triaxial testing machine (1,0mm/min). Results: The values (Newton) and standard deviations obtained were: Control Group û 394,25 ± 56,17N; Group ActiV GP û 263 ± 89,32N; Group Thermafil û 198,17 ± 61,65N; Group AH Plus û 158,08 ± 31,56N; Group Real Seal û 154,92 ± 42,64N and Group GuttaFlow û 107,92 ± 20,72N. The data were submitted to ANOVA e Dunett tests (5%). Conclusions: Among the experimental groups, roots filled with ActiV GP showed the highest values of resistance of load vertical was applied, and were similar to Control Group and Thermafil. AH Plus, Real Seal and Thermafil groups showed statistical similar fracture resistance. GuttaFlow Group showed the lowest values of fracture resistance.

ABSTRACT

Objetivo: Avaliar a utilização da tomografia computadorizada como opção para diagnosticar fraturas radiculares verticais. Métodos: Foram utilizados dez dentes humanos extraídos que apresentavam fraturas radiculares verticais sem a separação dos fragmentos. Os dentes foram previamente lavados com hipoclorito de sódio 0,5% e limpos com curetas periodontais para remoção de sujidades. As trincas radiculares foram confeccionadas baseadas na metodologia descrita por Fachin & Aun¹ e Aun & Silva². Os mesmos foram posicionados em um crânio seco, para realização das tomadas radiográficas periapicais, com a técnica do paralelismo. Para a tomada radiográfica, valendo-se da técnica do paralelismo, foi adaptado um posicionador para filmes radiográficos tipo "Hanshin" fixo ao crânio com auxílio de fita adesiva. O mesmo dente foi submetido à tomografia computadorizada. Para a comparação das técnicas, as imagens foram analisadas por três cirurgiões-dentistas endodontistas e dois radiologistas. Resultados: Observou-se que pela avaliação das radiografias periapicais, somente uma das fraturas foi detectada. Os laudos tomográficos apresentaram fraturas detectáveis em todos os dentes. Conclusão: O exame tomográfico, além de ser amplamente utilizado na implantodontia, foi o método que melhor possibilitou o diagnóstico de fraturas radiculares verticais, permitindo a detecção, localização e extensão da fratura.


Objective: Assess the use of computed tomography for the diagnosis of vertical root fractures. Methods: Ten extracted human teeth with vertical root fractures without separation of the fragments were used. The teeth were washed with a 5% sodium hypochlorite solution and cleaned with periodontal curettes to remove dirt. Root cracks were made according to the methodology described by Fachin & Aun¹ and Aun & Silva². The teeth were then placed in a dry skull for taking the periapical radiographs using the parallel technique. For the radiograph using the parallel technique, a Hanshin mounting frame for radiographic films was attached to the skull with an adhesive tape. The tooth was then subjected to computed tomography. The images were analyzed by three endodontists and two radiologists for comparison of the techniques. Results: Assessment of root radiographs allowed detection of only one of the fractures. On the other hand, fractures were detected in all teeth when computed tomography was used. Conclusion: Computed tomography is not only widely used in implantology, but is also the method that best allowed the diagnosis of vertical root fractures. In addition to detecting the fractures, it was also possible to determine their location and size.
