“…The energy produced by ultrasonic vibration is dissipated from the device tip to the post and absorbed by dentin 16. Heat is dissipated through the periodontal tissues and bone, causing irreparable damage such as bone resorption and ankylosis 17,18,19. Ultrasonic devices produce mechanical waves at a frequency between 25 and 30 kHz 16.…”

“…Ultrasonic energy is produced by converting one form of energy into another. Magnetostrictive ultrasonic devices operate due to the application of an alternating current in the coils with ferromagnetic wire in the handpiece that cause it to vibrate 7,19. The piezoelectric devices operate due to the oscillation of quartz plates coupled to the handpiece 16,19.…”

“…Magnetostrictive ultrasonic devices operate due to the application of an alternating current in the coils with ferromagnetic wire in the handpiece that cause it to vibrate 7,19. The piezoelectric devices operate due to the oscillation of quartz plates coupled to the handpiece 16,19. The oscillation generated, irrespective of the type of device used, produces heat that frequently affects the supporting tissues 7…”

“…Besides the type of device selected, other factors also influence the effectiveness of posts removal procedure: the method of ultrasonic vibration application, the use or not of cooling during the process, diameter and height of the post, tip movement type, which may be continuous or alternating, and the design of the ultrasonic tips 1,19,22,23,24,25. Several studies have reported techniques and devices that facilitate the removal of intraradicular posts.…”

ObjectivesTo evaluate the effect of different ultrasonic tip designs on intraradicular post removal.Materials and MethodsThe crowns of forty human canine teeth were removed, and after biomechanical preparation and filling, the roots were embedded in acrylic resin blocks. The post spaces were made, and root canal molding was performed with self-cured acrylic resin. After casting (Cu-Al), the posts were cemented with zinc phosphate cement. The specimens were randomly separated into 4 groups (n = 10), as follows: G1 - no ultrasonic vibration (control); G2 - ultrasonic vibration using an elongated cylindrical-shaped and active rounded tip; G3 - ultrasonic vibration with a flattened convex and linear active tip; G4 - ultrasonic vibration with active semicircular tapered tip. Ultrasonic vibration was applied for 15 seconds on each post surface and tensile test was performed in a Universal Testing Machine (Instron 4444 - 1 mm/min).ResultsG4 presented the highest mean values, however, with no statistically significant difference in comparison to G3 (P > 0.05). G2 presented the lowest mean values with statistically significant difference to G3 and G4 (P < 0.05).ConclusionsUltrasonic vibration with elongated cylindrical-shaped and active rounded tip was most effective in reducing force required for intraradicular post removal.

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).
