Sponsored by Second Affiliated Hospital, School of Medicine, Zhejiang University · Observational
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.

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.

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.

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.
