Full textAbstract:
The prognosis of endodontically treated teeth depends not only on the success of the endodontic treatment, but also on the type of reconstruction. The use of fiber-reinforced resin (FRR) posts to restore endodontically treated teeth has gained popularity due to its mechanical and esthetic characteristics as well as properties of modern adhesive systems. The aim of this article was to show a clinical technique to reconstruct endodontically treated teeth with great loss of tooth structure using direct fiber-reinforced post systems and direct composite restorations. The first case was a patient with the fractured right second lower premolar. The tooth was endodontically treated and reconstructed thereafter. After the preparation of the root canal and cementation of a FRR post, particular attention was paid to the incremental and curing techniques adopted to reconstruct coronal part of the tooth. The second case was a patient with the fractured first right lower incisor. This tooth was treated in the same way. Direct composite reconstruction of endodontically treated teeth is an alternative to the prosthodontic therapy and can postpone prosthodontic therapy for a long time.

Structure of the anterior teeth after endodontic treatment usually become weak because of the extensive loss of toothstructure. It causes a big problem to an endodontically treatment tooth when considering its restoration, examplereduced strength of the remaining tooth structure. Restoration that covers the tooth crown can be used if aesthetic andfunctional problems factors have been considered. However, composite resins are also often the treatment of choice forthe restoration of endodontically treated tooth. In this literature review, it will be discussed the selection of the properrestoration of the anterior teeth that have been endodontically treated.

ABSTRACT Pulpal pain does not refer to an endodontically treated tooth. Nevertheless, such a potential may exist based on a learned phenomenon due to previous treatment experiences but is rarely reported. Further, it is seldom reported to occur with atypical features. This case report is on a patient who was presented with pain in endodontically treated lower first molar (36) and recommended to undergo retreatment. However, endodontic treatment in 26 relieved the pain showing occurrence of referred pulpal pain in 36. But due to atypical referral and unknown endodontic status in 36, only uneventful follow-up confirmed the retrospective diagnosis of referred pulpal pain in 36. Pulpal pain can refer to an endodontically treated tooth based on learned phenomenon. Such a referral can also occur with atypical features and pose a diagnostic dilemma. Therefore, referred pulpal pain should be considered in the differential diagnosis of pain in an endodontically treated tooth. How to cite this article Pai ARV, Vikram M, Jain R.

A tooth can be broken due to many reasons, out of which deep cervical caries can be the one leading to destruction of the whole buccal surface of the tooth. So, to preserve such kind of tooth, root canal treatment is the ultimate treatment option followed by proper selection of the restorative means of such endodontically treated tooth. endodontically treated tooth (ETT) has loss of tooth structure and changes in physical characteristics. Therefore, proper selection of restoration for ETT is mandatory to maintain almost the same level of strength and regaining its functional abilities. The decision of doing restoration of endodontically treated teeth depends on many factors like the amount of tooth structure remaining, condition of the opposing tooth, etc. In cases of less than 50 % tooth structure remaining post and core followed by crown is the best treatment option. This article showcases a case report of treatment of anterior teeth with deep cervical caries. The posts used in these cases were fiber post which were luted and the core build up was done with ParaCore, which is a glassreinforced composite by Coltene. Deep cervical caries can lead to destruction of the whole buccal surface of the tooth. So, to preserve such kind of tooth, root canal treatment followed by proper selection of restoration for endodontically treated tooth is mandatory to maintain almost the same level of strength and to regain its functional abilities. This article showcases a case report of treatment of anterior teeth with deep cervical caries.

Neste estudo, foi avaliada a resistência à fratura de dentes que, já tratados endodonticamente, foram reconstruídos proteticamente com uma coroa de liga de NiCr (Verabond II), a qual era apoiada sobre núcleos compostos por diferentes materiais, obtidos por diferentes técnicas, cimentados no remanescente radicular com o ionômero de vidro Rely X Lutting 2, o qual é acrescido de resina composta. Esses núcleos eram do tipo metálico fundido, no grupo NMF; no grupo ANATO, a resina composta Filtek Z250 (3M ESPE, St. Paul-MN, USA) constituía o núcleo, contendo um pino de fibra de vidro (Reforpost Fibra de Vidro RX, Ângelus Indústria de Produtos Odontológicos Ltda.,Londrina-PR); este mesmo tipo de pino era utilizado no grupo PFFV, sendo diretamente cimentado, sem acréscimo de resina; finalmente, no grupo PFM, um pino metálico (no 064, FKG Dentaire S. A., La Chaux-de-Fonds, Swiss) era cimentado da mesma maneira descrita para o grupo anterior. Os remanescentes radiculares eram provenientes de dentes caninos superiores humanos, distribuídos aleatoriamente, compondo assim os quatro grupos, cada um com 10 espécimes: Os espécimes, após 24 horas da cimentação, foram submetidos a esforços cíclicos, em uma Máquina Eletro-Mecânica de Fadiga, aplicados no sentido do longo eixo dental, com carga de 20 N, na freqüência de 2,0 Hz, assim perfazendo um total de 250.000 ciclos. Excetuando-se 2 corpos-de-prova cujos núcleos soltaram-se da raiz, durante a carga cíclica, todos os demais foram submetidos a uma carga de compressão, numa máquina universal de ensaios (Kratos - Dinamômetros Ltda. São Paulo-SP), regulada na velocidade de 0,5 mm/min, com a força aplicada na face palatina da coroa, num ângulo de 45º em relação ao longo eixo dental, até a ocorrência da fratura radicular. Os valores de resistência encontrados foram os seguintes, em ordem decrescente: 47,677 kgf para o grupo NMF, 34,921 kgf para o PFM, 31,354 kgf para o PFFV e, 27,172 kgf para o ANATO. A análise de variância aplicada aos valores originais apontou diferença entre os grupos estudados e um subseqüente teste de Tukey (p<0,05) permitiu verificar semelhanças entre todos eles, com diferença significante apenas entre os grupos NMF e ANATO.In this study, was evaluated the strength of endodontically treated teeth, had been reconstructed with a crown of NiCr alloy (Verabond II), which was supported by a post and core for different materials, gotten for different techniques, cemented in the root with the glass ionomer Rely X Lutting 2, which is increased of composed resin. These diferents post and cores were of the casting metallic type, in group NMF; in group ANATO, the composed resin Filtek Z250 (3M ESPE, St. Paul-MN, USA) was the core, contend a glass fiber post (Reforpost Fibra de Vidro RX, Ângelus Indústria de Produtos Odontológicos Ltda., Londrina - PR); this exactly type of post was used in group PFFV, being directly cemented, without resin addition on the core; finally, in group PFM, a metallic post (064, FKG Dentaire S. , La Chaux-of-Fonds, Swiss) were cemented in the same way described for the previous group. All the roots were proceeding from maxillary human canines, randomly distributed, thus composing the four groups, each one with 10 specimens: The specimens, after 24 hours of the cimentation, had been submitted the cyclical efforts, in an Electromechanical Machine of Fatigue, applied in the direction of the long dental axle, with load of 20 N, in the frequency of 2 Hz, thus occuring a total of 250.000 cycles. Excepting 2 body-of-test whose post and cores had been freed of the root, during the cyclical load, all excessively had been submitted to a compression load, in a universal machine of assays (Kratos - Ltda. Dinamômetros. São Paulo - SP), regulated in the speed of 0,5 mm/min, with the force applied in the lingual face of the crown, in an angle of 45º in relation to the long dental axle, until the occurrence of the any root fracture. The joined values of resistance had been following, orderly the decreasing one: 47,677 kgf for group NMF, 34.921 kgf for the PFM, 31,354 kgf for the PFFV and, 27,172 kgf for the ANATO. The analysis of variance applied to the original values pointed difference between the studied groups and a subsequent Tukey test (p<0,05) it allowed to verify similarities between all they, with significant difference only between groups NMF and ANATO.

Facto este, devido à vasta quantidade de soluções existentes, que tornam mais difícil a escolha do plano de tratamento mais adequado, que tenha os máximos benefícios funcionais, biológicos e estéticos. Objetivo: Demonstrar, de uma forma muito sucinta as várias modalidades existentes para restauração de dentes endodonciados, nomeadamente as suas indicações, vantagens e desvantagens e o seu prognóstico, e, por outro lado, mostrar soluções para resolver problemas extremamente comuns inerentes a este tratamento, tais como, o escurecimento do dente em comparação com os seus adjacentes. Materiais e Métodos: Revisão bibliográfica tendo por base as palavras-chave delineadas e critérios de inclusão e exclusão específicos, com o objetivo de angariar e debater o máximo de informação acerca desta grande controvérsia da Medicina Dentária. Resultados e Conclusões: Existem inúmeras soluções para restaurar dentes endodonticamente tratados. Todas estas apresentam vantagens, desvantagens e indicações bastante específicas. Assim, é de extrema importância ter um profundo conhecimento acerca das mesmas, a fim de escolher a melhor modalidade de tratamento, com os melhores resultados funcionais, biológicos e estéticos. Visto, atualmente, a vertente estética dos tratamentos revela-se equiparadamente importante. Também, é relevante referir que existem soluções para dentes endodonciados que apresentam o problema mais frequente decorrente do tratamento, o escurecimento do dente em comparação com os adjacentes. A fim de solucionar este problema, defende-se o branqueamento interno do dente, que tem vindo a demonstrar ótimos resultados e excelentes prognósticos.
Introduction: The restoration of the teeth that went through endodontic treatment is one of the subjects that generate controversy in Dentistry. This happens because there’s a lot of solutions that make harder choosing the most suitable treatment plan. It has to include the most functional, biological and aesthetic benefits. Objective: To show, briefly, the many existing modalities to endodontic teeth restauration; namely its indications, advantages and disadvantages and its prognosis. On the other hand, to show solutions to solve extremely common problems due to this treatment. An example of this is the tooth darkening in comparison to its adjacent. Materials and Methods: Bibliographic review based on outlined keywords and specific inclusion and exclusion cryteria, with the objective of raising and debating as many information about this huge controversy as possible. Results and Conclusions: There are countless solutions to restore endodontically treated teeth. All of these have advantages, disadvantages and very specific indications. So, it’s really important to have a deep knowledge about them, in order to choose the best treatment modality, with the best functional, biological and aesthetic results. Currently, the aesthetic slope of the treatments is indeed considerable, so it’s also important to refer that there are solutions for endodontic teeth that feature its darkening in comparison to its adjacent (the most frequent disadvantage during the treatment). To solve this problem, it is advocated the internal teeth bleaching, which has been showing great results and excellent prognosis.

Conselho Nacional de Desenvolvimento Científico e TecnológicoThe aim of this study was to evaluate the biomechanical effect of the presence and number of fibreglass post in endodontically treated molars restored with composite resin. 45 human molars were selected, included in polystyrene resin cylinders with simulation of the periodontal ligament and endodontically treated. These teeth were randomized into three groups (n = 15): Wfgp, without fibreglass post and restored with Filtek Z350 XT; 1fgp, 1 fiberglass post Exact #2 cemented in the distal root with RelyX U200 and restored with Z350XT; and 2fgp, 2 fiberglass posts cemented with RelyX U200, one in the distal root and the other in the mesiobuccal root, restored with Z350XT. The specimens were submitted to mechanical fatigue with axial load of 50N. The tooth remaining deformation was measured using extensometers (n = 10) during occlusal loading of 100N and then until fracture. The other teeth (n = 5) were used to calculate the modulus of elasticity (GPa) and Vickers hardness (VH, N/mm2) of the enamel, dentin composite resin and fiberglass post in two positions: parallelly and transversally to the long axis of the post. The stress distribution was analyzed using three dimensional finite elements model, generated from micro-CT image of an intact tooth with its geometry similar of those used in the in vitro study. The calculated mechanical properties were used to characterize models of finite element analysis. The data of deformation and fracture resistance were tested for normality (Shapiro-Wilk) and equivalence of variances (test Levene), followed by parametric statistical tests appropriated for each test. One way Anova was performed for the axial compressive strength values, tooth remaining deformation and fracture resistance. Multiple comparisons were performed using Tukey test. The mean fracture data were submitted to the Chi-square test. Factorial analysis of variance on two factors was carried out considering as factors in study: the tooth surface deformation (B and L) and rehabilitation technique. All tests done had significance level α = 0.05 and all analyses were performed with the statistical program Sigma Plot version 13.1 (Systat Software, San Jose, CA, USA). The use of two fiber glass posts resulted in lower fracture resistance than the groups without fiber glass - 22 - post and with one fiber glass post. During occlusal loading of 100N lingual surface of the remaining tooth showed higher deformation for all groups. The absence of fiber glass post resulted in significantly higher values of stress in the root and more irreparable fracture modes than the other groups. The use of a fiber glass post resulted in better ratio deformation/fracture resistance. The concentration of stress in the furcation area was slightly reduced with use of fiber glass post. It is concluded that the use of one fiber glass post to rehabilitated molars with direct composite resin showed higher resistance to fracture than the use of two fiberglass posts, lower tooth remaining deformation, better stress distribution and failure pat more repairable when compared to molars restored without use of fiber-glass post
O objetivo deste trabalho foi avaliar o efeito biomecânico da presença e do número de pinos de fibra de vidro em molares tratados endodonticamente e restaurados de forma direta com resina composta. Quarenta e cinco molares humanos foram selecionados, incluídos em cilindros de resina de poliestireno com simulação do ligamento periodontal e tratados endodonticamente. Estes dentes foram randomizados em três grupos (n=15): Spfv, sem pino de fibra de vidro, restaurado com Filtek Z350XT; 1pfv, 1 pino de fibra de vidro Exacto Nº 2 cimentado no canal distal com RelyX U200 restaurado com Z350XT; e 2pfv, 2 pinos de fibra de vidro Exacto Nº 2 cimentados com RelyX U200, um no canal distal e o outro no mesio-vestibular restaurado com Z350XT. As amostras foram submetidas à fadiga mecânica com carregamento axial de 50N. A deformação do remanescente foi mensurada usando extensômetros (n=10) durante o carregamento oclusal de 100N e em seguida até o momento de fratura. Os demais dentes (n=5) foram usados para calcular o módulo de elasticidade (E, GPa) e dureza Vickers (VH, N/mm2) do esmalte, dentina, resina composta e pino de fibra de vidro em duas posições: paralelamente e transversalmente ao longo eixo do pino. A distribuição de tensões foi analisada usando modelo tridimensional de elementos finitos gerado a partir de imagem de micro-CT de um dente hígido com medidas e geometrias representativo das amostras usadas na etapa experimental. Às propriedades mecânicas calculadas foram utilizadas para caracterizar os modelos da análise por elementos finitos. Os dados de deformação e resistência à fratura foram submetidos à teste de normalidade (Shapiro-Wilk) e equivalência de variâncias (teste de Levene), seguido por testes estatísticos paramétricos adequados para cada tipo de ensaio. Análise de variância em fator único foi realizada para os valores de resistência à compressão axial, deformação do remanescente e resistência à fratura. Comparações múltiplas foram realizadas usando teste de Tukey. Os dados de padrão de fratura foram submetidos ao teste Quiquadrado. Análise de variância fatorial em dois fatores foi realizada considerando como fatores em estudo: deformação da superfície do remanescente (V e L) e a técnica de reabilitação. Todos os testes empregados - 19 - tiveram nível de significância α=0,05 e todas as análises foram realizadas com o programa estatístico Sigma Plot versão 13.1 (Systat Software Ins, San Jose, CA, USA). O uso de dois pinos de fibra de vidro resultou em menor resistência à fratura que os grupos sem pino de fibra de vidro e com um pino de fibra de vidro. Durante o carregamento oclusal de 100N a superfície lingual do remanescente demonstrou maior deformação para todos os grupos. A ausência de pino de fibra de vidro resultou em valores significativamente mais elevados de tensões na dentina radicular e modos de fratura irreparáveis significativamente maiores que os outros grupos. O uso de um pino de fibra de vidro resultou em melhor razão deformação/resistência fratura. A concentração de tensão na área de furca foi ligeiramente reduzida com uso de pino de fibra de vidro. Conclui-se que o uso de um pino de fibra de vidro para reabilitar molares inferiores com resina composta direta mostrou maior resistência à fratura que o uso de dois pinos de fibra de vidro, menor deformação do remanescente, melhor distribuição de tensões e padrão de falha com maior número de fraturas reparáveis quando comparado a molares restaurados sem uso de pino de fibra de vidro

O tratamento endodôntico associado à restauração direta com resina composta tem sido utilizado para restaurar molares severamente destruídos em pacientes jovens. O objetivo deste estudo foi avaliar o efeito de diferentes níveis de perda de estrutura dentária antes e após a realização de tratamento endodôntico e restauração com resina composta bulk fill na distribuição de tensões e magnitude da força de mordida. Foram selecionados três pacientes jovens (9, 10 and 12 anos de idade) com primeiros molares com cárie extensa e envolvimento pulpar com diferentes níveis de perdas de estrutura dentária: PI, manutenção das duas cristas marginais e de todas as cúspides; PII, manutenção de pelo menos uma crista marginal e perda mínima de uma cúspide; e PIII, perda de ambas as cristas marginais, mantendo apenas as cúspides vestibulares. Os molares foram tratados endodonticamente utilizando técnica de instrumentação rotatória e obturados com guta-percha e cimento AHPlus (Dentsply) e em seguida foram restaurados com Filtek Bulk Fill Posterior (3M ESPE). A força de mordida em Newtons (N) foi mensurada antes e após a intervenção endodôntica e restauradora na posição habitual de oclusal usando aparelho de força de mordida por meio de uma célula de carga (Kratos). Tomografias computadorizadas cone beam foram realizadas antes e após o procedimento endodôntico/restaurador, e arquivos DICOM (.dcm) foram exportados para o software Mimics, 3-Matic (Materialize) e Patran (MSC Software) para criação dos modelos específicos dos pacientes nos dois momentos experimentais. A aplicação de carga foi simulada por contato oclusal dos dentes antagonistas nas cargas mensuradas clinicamente em cada momento. Nos modelos que representam as condições iniciais foram aplicados tanto os valores de força de mordida (N) mensurados no momento inicial quanto após o procedimento reabilitador: PI. 30,1/136,6; PII. 34,3/133,4 e PIII. 47,9/124,1 e para os modelos que representam a condição final foram utilizados os valores obtidos após a intervenção endodôntica e restauradora: PI. 136,6; PII. 133,4 e PIII. 124,1. As restaurações foram avaliadas após 2 anos. Após intervenção endodôntica e restauradora a força de mordida aumentou em 260% (de 36,7±11,6 para 12 131,9±17,8). Antes da intervenção endodôntica e restauradora, as tensões se concentraram na estrutura coronal e, após a reabilitação foram transferidas de forma homogênea para a dentina radicular, independente do nível de perda de estrutura dentária. Quando a carga final foi aplicada nos modelos de condições iniciais, evidenciou-se elevada concentração de tensão em áreas enfraquecidas e na região de furca. As restaurações apresentaram desempenho adequado após 2 anos. A presença de cárie extensa com envolvimento pulpar afetou negativamente a carga de mordida e aumentou a concentração de tensão na estrutura frágil o que pode favorecer à ocorrência de fratura dental. O tratamento endodôntico associado à restauração direta em resina composta bulk fill demonstrou ser um método eficiente para restabelecer o desempenho mastigatório e a eficiência biomecânica dos molares jovens com comprometimento severo da estrutura coronária.
Endodontic treatment (ETT) followed by direct composite resin restoration has been used for rehabilitating the severely damage molar teeth in young patients. The aim of this study was to evaluate the effect of the molar teeth with different levels of the dental structure loss before and after the ETT and direct restoration with bulk fill resin composite on the stress distribution and the bite force magnitude. Three young patients (with 9, 10 and 12 years old), with the first mandibular molar teeth with deep occlusal caries with pulp involvement were selected attending with different levels of the dental structure loss: PI, both marginal ridge and all cusps; PII, maintenance of one marginal ridge and loss of one cusp; and PIII, loss of both marginal ridge, maintaining only buccal cusps. ETT was restored using Filtek Bulk Fill Posterior (3M ESPE). The bite forces in Newtons were measured initially and postoperatively for all teeth in habitual bite force using a miniload cell. Cone-beam tomography imaging was performed, and the Digital Imaging and Communication in Medice (.dcm) files were exported to Mimics, 3-Matic (Materialise) and Patran (MSC Software) software to create a patient-specific FEA models. Bite load was carry out using contact load applied by antagonist teeth in two moments: without ETT and restoration: PI. 30.1/136.6; PII. 34.3/133.4 and PIII. 47.9/124.1; and after restorative procedure: PI. 136.6; PII. 133.4 and PIII. 124.1 N. Performing ETT and bulk fill resin composite restoration the bite load increased 260% (36.7±11.6) to 131.9±17.8). The restorations were evaluated after 2 years. Before rehabilitation the stresses concentrated on weakened coronal dental structure and after rehabilitation they were homogeneously transferred to root dentin, irrespective of the level of the tooth structure loss. When the postoperatively bite load was applied on nontreated tooth models, high stress concentration on weakened areas was verified. The restorations performed perfectly after 2 years. The extensive caries with pulp involvement affected negatively the bite load and increased the stress concentration on weakened areas and at furcation favoring the tooth fracture. The ETT and bulk fill resin composite restoration showed to be an efficient method for rehabilitate the biomechanical performance of molar teeth of young patients severely compromised structurally.

Previous issue date: 2010-04-16Os estudos clínicos de dentes desvitalizados e restaurados com pinos mostram resultados semelhantes no que diz respeito ao percentual de falhas ou insucessos, apesar de tantas variações técnicas, metodológicas e operatórias entre eles. Os insucessos são maiores quando se tratam de elementos dentais coronariamente destruídos ou comprometidos periapicalmente. Com o objetivo de identificar o efeito das variações clínicas que influenciam na longevidade do tratamento e a prevalência de descimentação de pinos, cárie marginal, fraturas radiculares e de lesões periapicais, foi realizada uma análise retrospectiva do desempenho clínico de dentes restaurados com pino de fibra de carbono. Foram avaliados 139 dentes em 75 pacientes, três anos após a data de cimentação dos pinos. Os dentes foram submetidos a tratamentos endodônticos, incluindo preparos dos condutos para pino, e tratamentos restauradores, realizados pelo mesmo endodontista e protesista, respectivamente, segundo protocolos padronizados. Através de exame clínico, radiográfico, fotográfico, laudos endodônticos e informações obtidas de prontuários, os dentes foram classificados de acordo com: grupos dentais, modalidade de tratamento endodôntico recebida, intervalo decorrido entre a última sessão endodôntica e a cimentação do pino, morfologia do pino, quantidade de remanescente dentinário coronário após preparo protético e sistema da coroa protética utilizado. Não foram constatadas descimentações de pinos, fraturas radiculares, ou cáries, e a classificação foi favorável para 99,3% (138 dentes) dos tratamentos endodônticos realizados. De acordo com os parâmetros analisados, os resultados desse estudo revelaram que as variações clínicas identificadas, consideradas desfavoráveis, não foram fatores determinantes para o insucesso, partindo-se do conjunto de procedimentos e materiais utilizados para o tratamento dos dentes desses pacientes
Clinical studies of devitalized teeth restored with posts show similar outcomes with regard to the percentage of faults or failures, despite many technical variations, methodological and operative between them. The failures are greater when dealing with teeth coronally destroyed or periapically compromised. The aim of this study was identify the effect of clinical variants that influence the longevity of treatment and prevalence of dislodgment of post, marginal caries, root fracture and periapical lesions was performed a retrospective analysis of clinical performance of teeth restored with carbon fiber post. 139 teeth were evaluated in 75 patients, three years after the date of cementing the posts. The teeth were root canal treatments, including preparations of the conduits to posts, and restorative treatments, performed by the same endodontist and prosthetics, respectively, according to standardized protocols. Through clinical, radiographic, photographic, endodontic reports and information obtained from medical records, the teeth were classified according to: tooth groups, type of endodontic treatment received, time span between the last endodontic session and bonded post, morphology of the post, amount of remaining dentin after crown preparation and prosthetic crown system used. There were no dislodgment of post, root fractures, or caries, and the rank was favorably for 99.3% (138 teeth) of endodontic treatment. According to these parameters, the outcomes of this study revealed that the clinical variations identified, that are considered unfavourable, were not determining for the failure, starting from the set of procedures and materials used for dental treatment of these patients

Structure strength is a major complication for endodontically treated teeth that usually restored with post and core to recover its function. While endodontically treated tooth is splinted to an implant in edentulous region for some clinical situations, complex biomechanical aspects of an endodontically treated tooth/implant-supported system are derived from the dissimilar mobility between the osseointegrated implant and the tooth and the weak structure strength of endodontically abutment tooth. Significant problems such as, loss of osseointegration, abutment screw loosening, prosthesis fracture and adhesive interface debonding between tooth and post arise due to the higher bending moment caused by the cantilever effect especially for the case of compromised periodontal support (not enough post length in alveolar bone). The aim of this study was to investigate the biomechanical aspects for endodontically treated tooth splinted to different implant system (ITI, Prima and Frialit-2 implant system) under four loading conditions: (1)OTOI: 100N oblique load (45o) on tooth and 200N oblique load on implant, (2)OT: 100N oblique load (45o) on tooth, (3)ATAI: 100N axial load on tooth and 200N axial load on implant, (4)AT: 100N axial load on tooth, using non-linear finite element (FE) approach. Moreover, to simulation the crack propagation of the cement, element birth and death technique and parametric design language provided in FE method was then adopted. The results showed the higher stability of the system after endodontically treated tooth splinted to the implant system but the stress values of the implant system, alveolar bone, and adhesive cement also increased. In addition, the stress values in the remaining dentin, post and core, implant system, alveolar bone and adhesive cement increased significantly for splinted system with receiving oblique load. On the other hand, the stress values of bone and cement increased when splinting to ITI implant, and the stress values of dentin, post, and implant system itself increased when splinting to Frialit-2 implant system . As for the crack propagation of the cement, the results showed that the initial crack of the cement lied on the bottom between the prosthesis and abutment, and the crack grew upward along the abutment, then turn toward to the cement between prosthesis and remaining tooth. On the whole, occlusal adjustments need to perform to reduce lateral load for decreasing the stress distribution in different components (bone, adhesive cement, prosthesis and implant) of the splinted system. Moreover, in choosing the implant, the Prima system is recommended.

The system of computer aided design (CAD)/computer aided manufacture (CAM) of ceramic restoration has been generally used in dental restoration. Its main advantage is reducing time that takes in treatment. Performing restoration of crown is the main clinical treatment of cracked tooth in patients who already received endodontic treatment. However, preparation of using crown restoration would wear more remaining tooth. If we use inlay in restoration only, the fracture resistance of restored teeth are still based on clinical trials. Thus, it generates the question that how to make a balance between the resistances of restored tooth and the remaining tooth in treatment ofcracked tooth. The aim of this study were to compare the probability of survival of endodontically treated cracked tooth premolar in different crack depth with different CAD/CAM restoration configurations. Three dimensional finite element (FE) premolar model with five cracked tooth depth(upper periodontal bone margin (UB):1 mm,2 mm; below periodontal bone margin (BB): 1 mm,2 mm,3 mm) and eight different CAD/CAM restorations (inlay (with/without post), onlay (2 cusp coverage range, with/without post), endo-crown, crown) constructed by combining Micro-CT and CAE. Cracked tooth symptoms were created by using contact element to perform simulations. The rationality of FE model was validated by in vitro experiment and FE convergence test. The Weibull function was incorporated with FE analysis to calculate the long-term failure probability relative to different load conditions. The statics stress results indicated that the stress value on cement of inlay restorations were 9 times higher than the value of the other three restorations. The stress value of each material of endo-crown or crown were lower than inlay/onlay restorations 40% to 60%. Post design decreased the stress value of dentin, however as crack depth increased the decrease value of stress grew negative (from -8.5% to +20%). Weibull analysis revealed that the overall failure probability in the onlay endo-crown and crown were 30%, 2%, 1% respectively in normal occulsual condition (average 325N). The failure probability were 80% on onlay, 50% on endo-crown, 10% on crown when tooth under bruxim condition (average 660N). According to this study, tooth restored with inlay system were easily found fracture at cement layer. Onlay restoration system could provide 30% survival rate in normal occlusal condition, however it is not proper in bruxim condition. The numerical investigation suggests that crown restorations could provide more safy for endodontically cracked tooth than other indirect restorations.

Full textAbstract:
A tooth that has been properly treated endodontically should have a good prognosis. It can resume full function and if necessary serve satisfactory as an abutment for a fixed and removable partial denture. However special techniques are needed to restore such a tooth. Traditionally, a pulpless tooth received a dowel or post to “reinforce” it and a crown to “protect” it. Until the introduction of ZnPO4 cement in the last century. The major problem with their use was that of post retention. Currently, the clinician can use a variety of port and core systems for the different endodontic and restorative requirements. However, no single system provides the perfect restorative solution for every clinical circumstance, and each situation requires individual evaluation.

Full textAbstract:
Endodontics remains a rapidly advancing branch of restorative dentistry. It is highly likely that, by the time this book is published, several new or updated endodontic file systems will have been released. Despite the fairly rapid technological advances that the profession has seen, the key principles of endodontic treatment remain the same: 1. Eliminate microorganisms from the root canal system 2. Prevent reinfection of the root canal system 3. Retain a functional natural tooth. Whilst these principles are easy to discuss, they are consistently difficult to perform, due, in large part, to the complexity of the root canal system. Multiple theories, principles, and approaches have been discussed to help achieve an optimal technical and clinical outcome. However, evidence to favour one specific stage or system over another is lacking, and as such, a large degree of operator preference and experience will ultimately influence the treatment planning and technical strategy. Much like baking a cake, endodontic treatment relies upon a series of procedural steps to achieve a desirable outcome, which, for the patient, often equates to a functional, pain-free natural tooth. Good- quality magnification remains a key component of an endodontist’s armamentarium, and dental loupes or a dental operating microscope could not be recommended more highly. Key topics include: ● Endodontic case assessment, including root canal anatomy ● Pain management, including local anaesthesia ● Access and canal identification ● Vital pulp therapy, including caries management ● Canal negotiation and instrumentation ● Root canal irrigation ● Root canal obturation ● Restoration of the endodontically treated tooth.

Full textAbstract:
This textbook has covered the common causes of broken down teeth: dental caries, tooth wear, and trauma. In addition, long-term failure of parts, or all, of the existing tooth–restoration complex can be significant and may require further operative intervention for its successful management (see Chapter 9). Many intra-coronal defects can be repaired with direct adhesive restorations, as discussed in Chapters 5 and 9. However, the situation can be complicated by the loss of significant portions of existing restoration or tooth structure (e.g. cusps, buccal/lingual walls), which influence the restorative procedures used in an attempt to maintain the tooth longevity, as well as pulp viability, for as long as possible. For direct restorations to succeed clinically, they require healthy dental tissues to aid support, retention, and ideally provide an element of protection from excessive occlusal loads. With diminishing amounts of tooth structure to work with, greater thought and care are required to manage and prepare the remaining viable hard tissues to support and retain the larger restoration. The core restoration describes the often large direct plastic restoration used to build up the clinically broken down crown. It is retained and supported by remaining tooth structure wherever possible (sometimes including the pulp chamber and posts in root canals of endodontically treated teeth). These large restorations often benefit from further overlying protection to secure their clinical longevity, by means of indirect onlays, and partial or full coverage crowns. Before carrying out a detailed clinical examination of the individual tooth and the related oral cavity, it is always important to justify your clinical decisions, for both operative and non-operative preventive interventions. The five key reasons for minimally invasive (MI) operative intervention are:… • to repair hard tissue damage/cavitation caused by the active, progressing caries/tooth-wear process (where non-operative prevention has failed repeatedly) • to remove plaque stagnation areas within cavities/defects which will increase the risk of caries activity due to the lack of effective plaque removal by the patient • to help to manage acute pulpitic pain caused by active caries by removing the bacterial biomass and sealing the defect, thereby protecting the pulp • to restore the tooth to maintain structure and function in the dental arch • aesthetics.

The aim of the present study is to obtain the stress distribution pattern on the different domains of the tooth in the oral cavity, taking into account non linear properties of the periodontal ligaments (PDL)surrounding the tooth. The stresses and deformation under the action of chewing forces are studied to estimate the risk of tooth fractures. Initially, linear stress and deformation analysis is carried out with three posts different in constitution. However, considering the role of periodontal ligaments, which ensures uniform stress distribution in tooth structure, due to its elastic and non-linear properties, it is felt necessary to simulate the model for non linear analysis. The study reveals that non-linear analysis gives more realistic results as compared to linear analysis. It is observed that under similar loading conditions, the stresses are approximately 25% less in case of non linear analysis and the deformation is 50% more as compared to linear static analysis for an endodontically treated maxillary central incisor. The Dentist can do selection of optimum post core system with better accuracy.
