The phrase "a gcf of" is correct and usable in written English.
It is typically used in mathematical contexts to refer to the "greatest common factor" of two or more numbers.
Example: "To simplify the fraction, we need to find a gcf of the numerator and denominator."
Alternatives: "the greatest common factor of" or "the highest common factor of".
However, daily plaque control resulted in the increase of GCF TIMP-1 levels regardless of CHX usage.
The examples of Figure 3 show the -coordinate of the maximum peak of a GCF map along time when two sources are active.
Moreover, our VEGF results corroborate with a previous study which reported a non-significant trend towards increased VEGF in GCF of patients with type 2 diabetes and chronic periodontitis compared to systemically healthy individuals with chronic periodontitis [ 49].
Similar results have also been observed in levels of TNF-α where a significant increase was seen only in GCF of treatment teeth (maxillary canines) at 24 h when compared to control and implant groups.
On a concentration basis, the PAF levels in the GCF of Perio + CHD group were significantly different from the PAF levels of the CHD group (p = 0.039).
In a recent study done to determine the resistin levels in GCF of patients with chronic periodontitis and healthy controls, it was observed that there were significantly increased levels of resistin in chronic periodontitis compared with the healthy controls [ 53].
To simplify a fraction, you have to find the greatest common factor (GCF) of both the numerator and the denominator.
PGE-2 and leukotriene B-4 were found in GCF of localized juvenile periodontitis (now called localized aggressive periodontitis), suggesting a role of these molecules in periodontal disease.
The aim of the present review was to study the efficacy of scaling and root planing (SRP) with and without adjunct antibacterial photodynamic therapy (aPDT) on the expression of cytokines in the gingival crevicular fluid (GCF) of patients with periodontitis.
