Gingival Crevicular Flow (Volume) As A Biomarker Of Orthodontic Tooth Movement, Harrison Truman, Nina Stevens, Tyler Starley

Excellence Day

Tooth movement is caused by the application of force. In short, applied force strains structures present in the PDL space – cells, ligaments, blood vessels. Cells in the PDL are damaged by extension and by diminished oxygen supply due to compression of blood vessels. Compounds released from damaged or dead cells trigger an innate inflammatory response. One of the biomarkers of that response is increased formation of extracellular fluid (edema), specifically gingival crevicular fluid (GCF). Our goal is to monitor changes of GCF flow during the orthodontic treatment with Invisalign.

A Review Of External Cervical Resorption, Sarah Makkiyah, Max Kazantcev

Excellence Day

Invasive cervical resorption (ECR) is a complex form of external resorption. It is distinguished by its localization, its invasive nature, and the formation of a mineralized replacement tissue resembling cellular cementum. During initiation of ECR, the portal of entry is the cementum below the gingival epithelium, and resorption starts with localized destruction and removal of PDL. Response to PDL injury includes formation of a blood clot and inflammation, followed by granulation tissue, recruitment of macrophages, and multinucleated-cell differentiation.
