Use of electrical stimulation for accelerated orthodontics in humans: a systematic review and meta-analysis.

Aim: The main objective of this systematic review is to comprehensively evaluate all the relevant studies to evaluate the effectiveness of electrical stimulation to accelerate orthodontic tooth movement in human patients.

Methods: Using a suitable search strategy, various databases like PubMed, CENTRAL, Scopus and Google Scholar were surveyed for relevant randomized controlled trials (RCTs); after which a hand search of related orthodontic journals was completed. The risk of bias of studies was checked using Cochrane's ROB-2 tool.
