“…In addition to removing fiber posts effectively from the root canal, the time required for disassembly is important. In a study comparing diamond burs, ultrasonic tools, and ultrasonic tools/carbide burs, the fiber post removal speed was found to be fastest for ultrasonic tools and carbide burs used together (Abe, da Silveira Bueno, De Martin, Davini, & Cunha, ). Aydemir et al () removed quartz fiber posts from root canals with the removal kit recommended by the manufacturer and with a stainless‐steel ultrasonic tip; they reported that use of the removal kit was significantly faster.…”

The aim of this in vitro study was to compare the efficacies of two different fiber post‐removal systems. Thirty extracted single‐rooted mandibular premolar teeth were used. After RelyX fiber posts were cemented, the teeth were divided into two groups with regard to the post removal techniques: ultrasonic vibration and D.T. Light‐Post removal kit. Residual material, tooth volume changes, working time and micro‐crack formation were assessed using micro‐computed tomography. All data were analyzed using Wilcoxon signed‐rank and Mann–Whitney U tests. There was significantly more tooth root volume change in the ultrasonic group than removal kit group (p < .05). Fiber post removal time for the ultrasonic group was significantly longer than the removal kit group (p < .01).

“…The sample size for this study was determined based on previous studies[ 1 3 , 14 ] using a power analysis program (G*Power Version 3.1.9.6, universitat kiel, Germany), which was determined to be 80 with a 0.5% confidence interval. A total of 80 extracted single-rooted human mandibular first premolar teeth of similar root diameter and length were selected.…”

“…[ 1 9 ] Although studies have evaluated the influence of post or cement types on bond strength or fracture resistance after post placement,[ 3 10 11 12 13 ] only few studies have evaluated the influence of fiber post and cement type on ease of removal (time) or fracture resistance after post removal. [ 1 8 , 9 14 ] Due to the ease of manipulation, self-adhesive resin cements are advocated for fiber post cementation as compared with regular self-etch adhesive technique, which is a sensitive as well as time-consuming procedure.

A BSTRACT Aims and Objectives: The aim of this study was to evaluate the time needed to remove two types of glass fiber posts cemented with two different cements and removed with two different techniques and to evaluate the fracture strength of teeth after post removal. Materials and Methods: Root canal treatment was completed in 80 extracted single-rooted premolars and the teeth were decoronated. Following canal preparation, the roots were coated with polysiloxane impression material and embedded in acrylic resin cubes. The specimens were randomly divided into eight experimental groups ( n = 10) based on the type of fiber post inserted: Reforpost (R) or Contec Blanco (C); luting cement: Multilink-N/self-etch (M) or G-Cem/self-adhesive (G); technique of removal: Peeso reamer (P); or ultrasonic (U). The posts were removed with respective technique under magnification and the time (in seconds) of post removal was determined. Following post removal, the fracture strength of the specimens was determined using a universal testing machine. The mode of failure was also determined. Data were analyzed by three-way analysis of variance (ANOVA), one-way ANOVA, Tukey’s post hoc test, t test, and correlation. Chi-square analysis was performed to compare the failure mode. Statistical significance was set at P < 0.05. Results: The post and cement types had an influence in post removal time ( P < 0.05). There was no role of post or cement types on the fracture strength of teeth after post removal with either technique ( P > 0.05). A weak negative correlation was found between the post removal time and fracture resistance for both Peeso reamer ( r = –0.373) and ultrasonic ( r = –0.177) techniques. Both techniques of post removal produced a majority of favorable failures ( P > 0.05). Conclusion: The type of post and luting cement plays a significant role in ease of post removal by Peeso reamer or ultrasonic technique. Post-removal technique had no effect on the fracture strength of teeth. Parallel serrated fiber post luted with self-etch resin cements was difficult to remove as compared with parallel smooth surface post luted with self-etch or self-adhesive resin cement.

“…Com a utilização ou não de ultrassom, sempre haverá presença de cimento aderente aos pinos e às paredes do canal (AGUIAR et al, 2014), embora a presença de agente de cimentação remanescente após a remoção dos pinos seja maior quando não é utilizada a vibração ultrassônica (ABE et al, 2014).…”

“…Uma cavidade pequena é feita no centro do pino utilizando broca diamantada número 1012 em alta rotação para permitir a introdução de uma broca Largo em baixa rotação. Essa cavidade no centro do pino pode ser feita até a metade do comprimento protético com broca de haste longa carbide esférica e posterior inserção ultrassônica (ABE et al, 2014). Uma lima ProFile 25/0.04 (Dentsply Maillefer ® ) no centro do pino e uma broca Largo número 2 (Dentsply Maillefer ® ) podem ser utilizadas na remoção do resto do pino e do cimento resinoso remanescente (SCOTTI et al, 2013).…”

Introdução: O retratamento não cirúrgico é uma opção de tratamento quando ocorre o insucesso no tratamento endodôntico, porém, em muitos casos, há necessidade da remoção prévia de pinos intrarradiculares. Objetivo: Esta revisão de literatura tem como objetivo citar os riscos e os benefícios da opção pelo retratamento endodôntico não cirúrgico na presença de pinos intrarradiculares, bem como citar materiais e técnicas para a remoção de diferentes tipos de pinos. Conclusão: A opção pelo retratamento endodôntico não cirúrgico, em casos em que há necessidade de remoção de pinos, é segura e de índice de sucesso considerável, por isso, deve-se levar em conta o conhecimento de técnicas e os fatores que podem influenciar durante o processo, a fim de prevenir acidentes, bem como saber que apenas a presença do pino intrarradicular não é indicação para o tratamento cirúrgico.
