Abstract
The gingival crevicular fluid (GCF) represents a valuable biological source for
understanding tissue responses during orthodontic tooth movement (OTM). While
traditional biochemical assays have provided insight into GCF composition, these methods are often labor-intensive, time-consuming, and require complex sample handling.
In recent years, vibrational spectroscopies, including Raman and infrared (IR) techniques, have emerged as innovative, noninvasive tools capable of detecting subtle biochemical and structural changes in biological fluids with minimal preparation.
This presentation explores the current knowledge and future potential of applying
vibrational spectroscopy to monitor individual biological responses during orthodontic
treatment with fixed appliances in permanent dentition.
Clinically, this research highlights the prospect of using GCF as a rapid, noninvasive
biomarker for treatment monitoring, particularly in adult patients at higher risk of root
resorption, such as those affected by periodontal disease, cleft lip and palate, arthritis, or systemic conditions. By reducing the need for multiple radiographs and invasive
assessments, this approach could pave the way for personalized, safer, and more efficient orthodontic care.


Learning Objectives
