Keratinized Gingiva Determines a Homeostatic Behavior of Gingival Sulcus through Transudation of Gingival Crevice Fluid

Table 2

Parametric t-test for intergroups analysis of gingival fluid flow rate according to the different collection methods before mastication stimulus.

Position	Group 1 (𝑛=16)			Group 2 (𝑛=16)
	Before	After	𝑃	Before	After	𝑃
P1A	0.82±0.79^a	0.72±0.64^A	0.54	0.33±0.38^b	0.68±0.79^A	0.04

Equal lowercase letters mean no significant differences between groups before mastication stimulus (𝑃≥0.05); different lowercase letters mean significant differences between groups before mastication stimulus (𝑃<0.05); equal capital letters mean no significant differences between groups after mastication stimulus (𝑃≥0.05); different capital letters mean significant differences between groups after mastication stimulus (𝑃<0.05).
