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. Periodontitis results in the loss of less than or equal to four teeth.

Exclusion Criteria:

• systemic illnesses
• pregnancy or lactation
• systemic antibiotics taken within the previous 6 months
• use of cholesterol reduction medication during the past 6 months
• subgingival scaling and root planing or surgical periodontal therapy in the last year
• chewing smokeless tobacco, smoking pipes or cigars 1 or more times per week, or smoking more than 20 cigarettes per week (1 pack per week) in the past 6 months

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
