During which stage of gingivitis does neutrophil infiltration and increased GCF happen?

Initial
Early
Established
Advanced

The correct answer is: Initial

During the initial stage of gingivitis, there is an accumulation of bacterial plaque that triggers an inflammatory response in the gingival tissues. Neutrophils are the first responders to the inflammatory process, and their infiltration into the gingival tissues increases during this stage. Additionally, there is an increase in Gingival Crevicular Fluid (GCF) production as a result of the inflammatory response. This indicates that the correct answer is the initial stage of gingivitis. In the early, established, and advanced stages of gingivitis, there is usually a progression of the disease with more severe inflammation, tissue damage, and involvement of other immune cells. These stages may present with different characteristics and levels of tissue involvement compared to the initial stage where neutrophils infiltration and increased GCF predominantly occur.
