Advance in Foot Function Enhancement Based on Foot Core System (review) / 中国康复理论与实践

Foot core system comprises active subsystem, passive subsystem and neural subsystem, which complement each other and provide different function for foot. Insufficient foot function (weak muscle strength, hypoesthesia of foot) is an important cause of foot injury, and aging, obesity and abnormal foot type are also possible factors of foot injury. At present, special foot strength enhancement methods, minimalist shoes training, and even the means of muscle/brain stimulation, can strengthen the intrinsic muscle strength of foot, improve the stability of the foot, increase the plantar sensory inputs, thereby enhance the core system, raise the foot function performance, and prevent sports injury.

Evaluación de la resistencia a la tensión entre diferentes sistemas de pernos intrarradiculares: estudio in vitro / Evaluation of tensile strength between different intraradicular bolt systems: in vitro study

La reconstrucción de los dientes tratados endodónticamente juega un papel importante en el pronóstico, ya que el 60% de los fracasos endodónticos se relacionan con la rehabilitación. Diversos sistemas y materiales se han utilizado en la reconstrucción de los dientes, alternando el diseño, material del perno, agente cementante y el tipo de muñón utilizado, evidenciando resultados contradictorios. Evaluar la resistencia a la tensión (RT) entre tres diferentes sistemas de pernos intrarradiculares. Se incluyeron 45 premolares monorradiculares, los cuales fueron instrumentados y preparados para ser reconstruidos con diversos sistemas de pernos. Estos fueron divididos en tres grupos: 1.-Sistema Perno-Muñón Colado (PMC), 2.-Sistema Para-Post Acero (PPA) y 3.-Sistema Para-Post Fiber-Lux (PPFL), cementados uniformemente con un cemento resinoso y sometido a RT en una máquina Instrom. La máxima RT fue para el sistema PMC (11.11 Mp), seguido por PPFL (3.42 Mp) y PPA con (3.14 Mp). La prueba de ANOVA complementada con el Post-Hoc DSH de Tukey reveló diferencias significativas entre PMC vs PPA y PPFL (p<0.05), entre PPA vs PPFL no hubo diferencias significativas. Ningún sistema prefabricado se desalojó a la prueba de tensión y los muñones se fracturaron. El sistema de PMC registró mayor RT que los sistemas PPA y PPFL (p<0.05) entre los prefabricados no existieron diferencias significativas

The reconstruction of teeth endodontically treated represents an important role, since the 60% of the endodontic failures relate to the rehabilitation. Diverse technical and material they have been utilized in the reconstruction of the posts, alternating the design, material, luting agent and the type of core utilized, showing contradictory results. Evaluating the tensional resistance (TR) of three post-endodontical reconstruction systems.Forty-five human premolars were used for this study, which were instrumented and prepared for receiving a post. They were divided into three groups: l. - casted post and core system (CPC), 2. - Steel Para-Post system (SPP) and 3. - Para-Post Fiber-Lux system (PPFL), which they were cemented with resinous cement and submitted to TR in Instrom machine. The maximum TR was for CPC (11.11 Mp), followed by PPFL (3.42 Mp) and SPP with (3.14 Mp). The ANOVA test supplemented with Post-Hoc HSD de Tukey´s revealed statistically differences significantly between CPC vs SPP and PPFL (p<0.05), among SPP vs PPFL do not there was statistically differences significantly. The prefabricated post, not there was dislocated and the cores were fractured. The CPC registered the higher TR that the prefabricated post (p<0.05) and among the prefabricated post did not exist differences significantly

Fatores determinantes na seleção de pinos intra-radiculares / Factors determining of intraradicular post selection

A reconstrução de dentes tratados endodonticamente freqüentemente requer a utilização de pinos e núcleos para o restabelecimento da estética e da função. A seleção de um apropriado sistema pino/núcleo é um dilema clínico, visto as amplas variedades disponíveis. O propósito deste artigo foi discutir os vários fatores que influenciam na seleção do pino e do núcleo, tais como comprimento da raiz, anatomia do dente, largura da raiz, configuração do canal, quantidade de estrutura dental coronária, força de torção, stress, desenvolvimento da pressão hidrostática, design e material do pino, compatibilidade do material, capacidade de adesão e retenção do núcleo, versibilidade, estética e material da coroa. Assim, baseadas na literatura consultada, algumas recomendações clínicas foram propostas no intuito de orientar o clínico na seleção do sistema pino/núcleo mais adequado para cada caso: 1) conservar o máximo de estrutura dental possível durante o preparo do conduto radicular; 2) pino e núcleo fundido personalizado são recomendados para canais radiculares não-circulares e quando se tem moderada a severa perda de estrutura dentária coronal; 3) pinos pré-fabricados paralelo, passivo, serrilhado e com auto-escape são recomendados para canais circulares pequenos; 4) pinos com fator anti-rotacional devem ser utilizados em situações com canais circulares; 5) adequado selamento apical deve ser mantido sem comprometer o comprimento do pino; 6) mais de um pino deve ser usado para dente curto multirradicular; 7) pinos paralelos passivos são preconizados pela adequada retenção, mas, quando a espessura de dentina apical é mínima, um pino com design paralelo-cônico deve ser indicado; 8) a capacidade retentiva da cabeça do pino facilita a retenção do material para o núcleo; 9) o pino deve assegurar compatibilidade do material, capacidade adesiva, adequada rigidez e compatibilidade estética com a restauração definitiva; 10) reversibilidade, em casos de falha, deve ser considerada; 11) o sistema deve ser de fácil uso e custo viável

The reconstruction of teeth treated endodontically frequently requests the use of post and core for the aesthetics and function restoration. The selection of an appropriate post-core system can be a clinical dilemma, seen the wide variety available. The purpose of this article was to discuss the several factors that influence in the selection of the post and core, such as root length, tooth anatomy, root width, canal configuration, amount of coronal tooth structure, torquing force, stresses, development of hidrostatic pressure, post design and material, material compatibility, bonding capacity, core retention, retrievability, esthetics and crown material. As it is, this article can serve as a guide to help the clinical in the selection of the post-core system. This way, based on the consulted literature, some clinical recommendations were proposed with the intention of guiding the clinical in the selection of the post-core system more appropriate for each case, being: 1) conserve as much remaining tooth structure as possible during the post space preparation, 2) custom-cast post and cores are recommended for noncircular root canals and when coronal tooth structure loss is moderate to severe, 3) parallel-sided, passive, serrated and self-venting prefabricated posts are recommended for small circular canals, 4) posts with an antirotational feature should be used in circular canals situations, 5) adequate apical seal must be maintained without compromising the post length, 6) more than one post must be used for multirooted short teeth, 7) passive parallel posts are advocated for adequate retention but when the apical thickness of dentin is minimal, a parallel-tapered combination post design may be preferred, 8) retentive qualities of the post head may facilitate firm retention of core material, 9) the post should ensure material compatibility, bonding ability, adequate rigidity, and esthetic compatibility with permanent restoration, 10) retrievability in the event of failure should be considered, and 11) the system should be easy to use and cost effective
