Evaluation of the Effect of using Electrosurgery in Pulpectomy of Deciduous Teeth on Succedaneous Teeth: An Animal Study

Abstract

Objectives: The aim of this study was to determine the probable side effects of electrosurgery in pulpectomy of deciduous teeth on succedaneous teeth in dogs. Materials and methods:In this animal study, all maxillary and mandibular teeth at one side of five puppies' mouths were treated employing electrosurgical pulpectomy and were then compared with those of the other side treated using the conventional method. The electrosurgical dental electrode was placed in canals to the point of working length for the experimental group. After pulpectomy, the canals were filled with zinc oxide eugenol paste and the access cavity was restored with amalgam. The dogs remained under care until their successor teeth erupted and clinical examination was performed. Results:The teeth treated employing electrosurgical pulpectomy presented natural appearance with no observable defects including enamel hypoplasia, diffuse opacities of enamel, demarcated opacities, and enamel discoloration. Conclusion:Electrosurgical pulpectomy can be considered as an option for pulpectomy of deciduous teeth.

Clinical and Radiographic Success of Electrosurgical Pulpectomy in Primary Teeth

“…Applying electrosurgery to a pulpectomy would also afford the aforementioned advantages, ensuring improved visualization and homeostasis among other things. In addition, electrosurgery does not seem to have any undesirable effect on the succedaneous permanent teeth 14) . The purpose of this study, therefore, was to compare the results of conventional pulpectomy with those of an electrosurgical approach in the treatment of the primary teeth by evaluating clinical and radiographic success rates over a 6-month follow-up period.…”

“…Despite all the progress that has been made in improving technology and methods aimed at improving prevention of dental caries and raising levels of awareness concerning the significance of maintaining normal dentition, teeth continue to be lost as it is too late to save them by the time the patient presents 10,14) . The removal of a diseased pulp in its entirety, including the pulp tissue in the roots, is referred to as a pulpectomy 12,13) .…”

“…Removing pulp from the root canals of the posterior primary teeth using conventional techniques can be time-consuming. One problem here, however, is that long endodontic treatment sessions are contraindicated in young children 14,16) . Moreover, shaping and cleaning the canals can also prove problematic, which has led to an extensive search for more effective instruments, materials, and techniques for this purpose.…”

“…All this effort is aimed at securing a faster and more effective way of preparing a canal for obturation. While conventional methods have insisted on using hand and rotary instruments, more recent approaches have applied laser technology, non-instrumentation techniques, and techniques employing ultrasonic or sonic equipment 9,14) . Moreover, clinicians are now interested in the biocompatibility offered by alternative approaches, as conventional treatment modalities incur significant disadvantages such as cytotoxicity, potential mutagenicity, and undesirable immune sensitization.…”

“…It also permits enhanced observation and produces results faster than conventional approaches such as formocresol pulpotomy 2,14,15) . Applying electrosurgery to a pulpectomy would also afford the aforementioned advantages, ensuring improved visualization and homeostasis among other things.…”
