Clinical Trial Summary

This study was a single-center, non-randomized, parallel-group design clinical trial, and each group was assigned a 1:1 ratio with or without hyperlipidemia. Both groups underwent periodontal non-surgical treatment, and blood and gingival crevicular fluid were collected before surgery, 1 month and 3 months after surgery for the detection of MCP-1, IL-8, oxLDL, TNF-α, TG, LDL-C, HDL-C.


Description:

This study was a single-center, non-randomized, parallel-group design clinical trial, and each group was assigned a 1:1 ratio with or without hyperlipidemia. Both groups underwent periodontal non-surgical treatment, and blood and gingival crevicular fluid were collected before surgery, 1 month and 3 months after surgery for the detection of MCP-1, IL-8, oxLDL, TNF-α, TG, LDL-C, HDL-C.MCP-1, IL-8, oxLDL, TNF-α will be tested for concentration using ELISA.

Eligibility Inclusion Criteria: - Subjects had to meet at least one of the following criteria for the diagnosis of hyperlipidemia: triglyceride (TRG) levels >2.26 mmol/L; high density lipoprotein cholesterol (HDL-C) levels <1.04 mmol/L; or low density lipoprotein cholesterol (LDL-C) levels >4.14 mmol/L - Patients with severe periodontitis (stage III/IV) with probing depth (PD) = 6 mm at at least six sites, at least two multi-rooted or two single-rooted teeth in at least one quadrant, and extended bone loss on imaging to the middle or top third of the root.

Secondary probing depth,PD The distance (mm) from the bottom of the periodontal pocket to the gingival margin was measured with a periodontal probe (UNC-15, Hu-Friedy, Chicago, IL) parallel to the long axis of the tooth. The mesial, median and distal 6 sites of the labial (buccal) and lingual surfaces were recorded for each tooth. Before surgery

The mesial, median and distal 6 sites of the labial (buccal) and lingual surfaces were recorded for each tooth. 3 months after surgery
Secondary clinical attachment level,CAL The periodontal probe measures the distance (mm) from the bottom of the gingival sulcus or the bottom of the periodontal pocket to the cementoenamel boundary. The mesial, median and distal 6 points of the labial (buccal) and lingual surfaces were recorded for each tooth. Before surgery

Secondary percentage of bleeding on probing,BOP% Gently probe to the bottom of the bag or gingival sulcus, take out the probe and observe for 10-15 seconds to see if there is any bleeding. The mesial, median and distal 6 sites of the labial (buccal) and lingual surfaces were recorded for each tooth. Calculate the percentage of bleeding sites. Before surgery
