Evaluation of the Effects of Routine Phase I Periodontal Therapy on Clinical Parameters and Levels of Gremlin-1, CTHRC1, and Tenascin-C in Gingival Crevicular Fluid and Peri-Implant Sulcular Fluid in Individuals With Periodontitis and Peri-Implantitis

The aim of this study is to compare the mechanisms of tissue destruction between natural teeth with periodontitis and implants with peri-implantitis within the same individual, and to evaluate the effects of routine Phase I periodontal therapy (scaling and root planing, and oral hygiene instruction). In this study, the tissue biomarker levels of Gremlin-1, CTHRC1, and Tenascin-C will be investigated. Gingival crevicular fluid (GCF) and peri-implant sulcular fluid (PISF) samples will be collected from subjects concurrently diagnosed with both periodontitis and peri-implantitis.
