Salivary S100A8, S100A9, S100A8/A9, and MMP-9 may be used for the screening of periodontitis in dogs, but with caution of other conditions that can affect their levels in saliva.
The highest values of sensitivity for the diagnosis of periodontitis were obtained for IL1beta (78.7%), followed by MMP8 (72.5%), IL6 and haemoglobin (72.0% for both molecules); the lowest sensitivity value was for MMP9 (70.3%).
To determine whether circulating levels of two matrix metalloproteinases, MMP-2 and MMP-9, are associated with loss of alveolar bone density (ABD) or height (ABH), or with progression of periodontitis (relative clinical attachment level [RCAL]), among postmenopausal women with local and systemic bone loss.
After adjusting for age, waist-to-hip ratio (WHR), glycated hemoglobin, smoking, education, and grip strength, the opposite sex role of periodontitis and obesity on CRP levels were confirmed.
The results of the meta-analysis revealed statistically significant differences in the MMP-9 levels in serum and GCF between patients with periodontitis and periodontally healthy control participants.
The present study aimed to compare levels of matrix metalloproteinase-9 (MMP-9) and myeloperoxidase (MPO) in gingival crevicular fluid (GCF) from subjects with controlled and noncontrolled Type 2 Diabetes Mellitus (T2D), with and without stage 2 grade B periodontitis (POD2B) versus healthy (H) subjects.
Matrix metallopeptidase-9 (MMP-9), which is known to be able to detect the progression of periodontitis in general, was not significantly different between OVX and Sham groups.
However, patients in the PD+RA+ group had significantly higher levels of rheumatologic parameters such as C-reactive protein (CRP), anti-cyclic citrulline peptide antibody (ACPA), erythrocyte sedimentation rate (ESR), and Disease Activity Score 28 (DAS28) than those in the PD-RA+ group.
Whereas the wGS<sub>CRP</sub> was not a modifier ( P<sub>interaction</sub> = 0.8) on the multiplicative scale, serum CRP modified the relationship between periodontitis and NAFLD ( P<sub>interaction</sub> = 0.01).
C-reactive protein (CRP) was significantly (<i>P</i> < 0.05) higher in the GCF of the periodontitis group while interleukin (IL)-8 was significantly (<i>P</i> < 0.01) higher in the GCF of the healthy group.
In summary, current evidence demonstrated that MMP-9-753 C/T polymorphism reduced the risk of periodontitis, MMP-3-1171 5A/6A and MMP-8-799 C/T polymorphisms increased the risk of periodontitis, and MMP-2-753 C/T was not associated with risk of periodontitis.
We have previously suggested that the Pro12Ala polymorphism represents a susceptibility factor for periodontitis, which is a known risk factor for increased CRP level.
Our results revealed that although studies of the association between MMP-8 -799 C/T variant and the susceptibility to periodontitis have not yielded consistent results, MMP-1 (-1607 1G/2G, -519 A/G, and -422 A/T), MMP-2 (-1575 G/A, -1306 C/T, -790 T/G, and -735 C/T), MMP-3 (-1171 5A/6A), MMP-8 (-381 A/G and +17 C/G), MMP-9 (-1562 C/T and +279 R/Q), and MMP-12 (-357 Asn/Ser), as well as MMP-13 (-77 A/G, 11A/12A) SNPs are not related to periodontitis risk.Conclusions.
This study aimed at investigating the association between interleukin-6 (IL-6), interleukin-12 (IL-12), C-reactive protein (CRP), vascular endothelial growth factor (VEGF) and β-defensin-1<sup> </sup>polymorphisms and the susceptibility to periodontitis in the Chinese population.
