Characteristics Of Gingival Crevicular Fluid Flow During Orthodontic Treatment With Invisalign, Nina Stevens

Orthodontics and Endodontics Theses

OBJECTIVES. Studies on quantitative relationships between magnitude of force applied to a tooth root and formation of gingival crevicular fluid (GCF) biomarkers (volume, concentrations of cytokines, enzymes, etc.) in clinical settings are lacking. This study aims to answer the question: What can analysis of GCF flow dynamic characteristics inform us about orthodontic tooth movement in a patient treated by Invisalign? METHODS. In three participants, two GCF samples were collected from five maxillary and five mandibular teeth during start, middle and end of Invisalign treatment. Plaque index and pocket depths were determined. Periopaper strips (Oraflow) were used for collection of GCF, …
