Effect of Low-Intensity Electrical Stimulation on External Apical Root Resorption and Periodontal Indices Following En-Masse Retraction of Upper Anterior Teeth in Young Adults: A Randomized Controlled Trial
Objective
To evaluate external apical root resorption (EARR) and periodontal indices during en-masse retraction of maxillary anterior teeth stimulated with low-intensity electrical currents.
Trial Design
A two-arm randomized controlled trial.
Methods
Young adult patients who visited the Department of Orthodontics at Damascus University between November 2023 and March 2024 and met predefined inclusion criteria were randomly allocated into two groups using block randomization. The study included 34 patients, with 17 assigned to the electrically stimulated en-masse retraction (ESER) group and 17 to the conventional en-masse retraction (CER) group. The force for the en-masse retraction technique in both groups was 250 g per side. The force was applied through bilateral closed-coil nickel-titanium springs anchored to an orthodontic mini-screw on each side. In the ESER group, each upper anterior tooth was subjected to a continuous electrical stimulation of 15–20 µA for 5 h daily, utilizing an intraoral removable electrical stimulation device. EARR was assessed using digital panoramic radiographs. Four periodontal indices were also used to assess periodontal status. Blinding was confined to data analysis.
Results
Thirty-four patients (26 females and 8 males) were analyzed with a mean age of 21.12 ± 2.41 years. At the end of the en-masse retraction phase, no significant difference in EARR was observed between the two groups (p > 0.05). The observed root resorption in the ESER and CER ranged between 0.27 and 0.64 and 0.32 and 0.71 mm, respectively. Also, insignificant differences were found in all periodontal indices studied at all measurement points between the two groups (p > 0.05).
Conclusions
Low-intensity electrical stimulation had no significant effect on root resorption during the en-masse retraction of the six upper anterior teeth. Both groups exhibited comparable slight root resorption without any significant difference between them. Additionally, low-intensity electrical stimulation did not affect the periodontal status during en-masse retraction.
期刊介绍：
Clinical and Experimental Dental Research aims to provide open access peer-reviewed publications of high scientific quality representing original clinical, diagnostic or experimental work within all disciplines and fields of oral medicine and dentistry. The scope of Clinical and Experimental Dental Research comprises original research material on the anatomy, physiology and pathology of oro-facial, oro-pharyngeal and maxillofacial tissues, and functions and dysfunctions within the stomatognathic system, and the epidemiology, aetiology, prevention, diagnosis, prognosis and therapy of diseases and conditions that have an effect on the homeostasis of the mouth, jaws, and closely associated structures, as well as the healing and regeneration and the clinical aspects of replacement of hard and soft tissues with biomaterials, and the rehabilitation of stomatognathic functions. Studies that bring new knowledge on how to advance health on the individual or public health levels, including interactions between oral and general health and ill-health are welcome.
