Brief Summary

The majority of previous studies for early detection of Orthodontically Induced Inflammatory Root Resorption (OIIRR) were conducted to assess individual biomarkers which are representative of single biological pathway. To our Knowledge, no studies have been employed Gingival crevicular fluid (GCF) proteomic analysis to identify potential biomarkers for OIIRR. Therefore; the aim of this study is to use the advantage of testing a package of biomarkers via doing proteomic analysis of GCF which could help in making a more precise personalize diagnosis and treatments, thereby providing orthodontists additional information that cannot be deduced from clinical parameters.

Masking Details
The GCF measures were coded by a clinician who bonded the appliance using patient ID number and the side of the arch (either right or left sides) to which orthodontic force (either heavy or light force) was allocated blindly for the investigator and outcomes assessor because the clinician could know the type of force from the shape of archwires. The surgeon who extract the teeth was also blinded. The extracted premolars were coded to be masked to the investigator who measured the root resorption areas. All outcome assessors of proteomic analysis as well as the statistician was blinded.
