Abstract
OBJECTIVE: This systematic review aimed to evaluate the effectiveness of current non-surgical methods in accelerating orthodontic tooth movement (OTM), focusing on low-level light therapy (LLLT) and mechanical vibration devices. The review sought to assess the current evidence regarding the efficacy of these interventions to inform clinical practice.
METHODS: The objective of this systematic review is to comprehensively assess the existing literature concerning non-surgical approaches, specifically low-level laser therapy (LLLT) and resonance vibration devices, as potential interventions for expediting orthodontic treatment. This evaluation seeks to provide valuable insights into their practicality in clinical settings.
RESULTS: Thirteen studies met the inclusion criteria, with six investigating LLLT and seven evaluating the effects of mechanical vibration devices. The findings indicate that while some studies reported reduced treatment times and enhanced rates of tooth movement with LLLT, results were inconsistent. Mechanical vibration devices did not demonstrate a significant impact on accelerating OTM in the majority of included studies. Risk of bias was variable across studies, with common issues including lack of blinding and inconsistent reporting of outcomes.
DISCUSSION: The results suggest that, although LLLT may have potential for accelerating OTM, the evidence remains inconclusive due to variability in study protocols and outcomes. Mechanical vibration devices showed no significant advantage over conventional treatment in accelerating OTM. The heterogeneity among studies, including differences in intervention protocols, outcome measures, and study populations, challenges any definitive conclusions.
CONCLUSION: Current evidence does not support a widespread adoption of LLLT or mechanical vibration devices as effective non-surgical methods for accelerating orthodontic tooth movement. Further research employing standardized intervention protocols and larger sample sizes is required to determine the clinical relevance of these technologies in orthodontic treatment planning.
