Inflammatory mediators for predicting the risk of trauma-induced root resorption: A systematic review.

Among the three sources, the inflammatory gingival crevicular fluid appeared to be the most non-invasive source of biomarkers for predicting trauma-induced root resorption, although the evidence about this came from two studies with moderate and one study with high risk of bias. The primary studies in this systematic review showed variability in terms of the sample sizes, age of the patients, the grading/classification of trauma-induced resorption and the evaluation methods which must be addressed by future researchers.
