Clinical Trial Summary

This study is to evaluate whether non-surgical periodontal therapy can help to control the cardiovascular risk among patients with moderate/severe periodontitis and at risk of cardiovascular disease.

Description:

Previous studies showed that the treatment of periodontitis can partially improve the control of risk factors of cardiovascular disease (e.g. blood pressure, interleukin 6), whereas the evidence is still limited. Moreover, there is currently no study reporting the impact of periodontal treatment on the overall risk of cardiovascular disease. The prevalence of periodontitis in China was 62.4%. In clinical practice, a large number of patients with moderate/severe periodontitis and at risk of cardiovascular disease seek medical advice. However, the existing guidelines lack relevant recommendations. Therefore, this study intends to evaluate whether non-surgical periodontal therapy can help to control cardiovascular risk.

376 patients with moderate/severe periodontitis and at risk of cardiovascular disease will be randomized. Those randomized to the intervention arm will receive non-surgical periodontal therapy which includes full-mouth subgingival scaling and root planing. Those randomized to the control arm will receive supragingival ultrasonic scaling. All patients were given instructions on basic oral hygiene.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change from Baseline Cardiovascular risk (Framingham risk score (FRS)) at 1 year.	Cardiovascular risk is assessed by "Framingham risk score (FRS)". (Circulation, 2008,117(6): 743-753.) Generally, the "Framingham risk score (FRS)" ranges from -4 to 33 for men and -5 to 33 for women. A higher "Framingham risk score (FRS)" means a higher risk of developing cardiovascular disease.	Baseline; 1 year
Secondary	Change from baseline systolic blood pressure at 1 year after enrollment.		Baseline; 1 year
Secondary	Change from baseline diastolic blood pressure at 1 year after enrollment.		Baseline; 1 year
Secondary	Change from baseline fasting blood glucose at 1 year after enrollment.		Baseline; 1 year
Secondary	Change from baseline glycosylated hemoglobin at 1 year after enrollment.		Baseline; 1 year
Secondary	Change from baseline total cholesterol at 1 year after enrollment.		Baseline; 1 year
Secondary	Change from baseline triglyceride at 1 year after enrollment.		Baseline; 1 year
Secondary	Change from baseline low-density lipoprotein cholesterol at 1 year after enrollment.		Baseline; 1 year
Secondary	Change from baseline high-density lipoprotein cholesterol at 1 year after enrollment.		Baseline; 1 year
Secondary	Change from baseline high sensitivity C-reactive protein at 1 year after enrollment.		Baseline; 1 year
Secondary	Change from baseline interleukin-6 at 1 year after enrollment.		Baseline; 1 year
Secondary	Change from baseline cardiovascular risk (CHINA-PAR) at 1 year after enrollment.	China-PAR is an abbreviation of "Prediction for ASCVD Risk in China". It is a prediction model developed by YANG X. (Circulation, 2016,134(19):1430-1440.) Through China-PAR, the investigators can assess one's cardiovascular risk in 10 years. The result of China-PAR is directly one's predicted cardiovascular risk in 10 years, ranging from 0% - 100%, with a higher probability meaning a higher risk of cardiovascular disease.	Baseline; 1 year
Secondary	Change from baseline community periodontal index at 1 year after enrollment.	Community periodontal index will be evaluated according to the guidelines by stomatologists. The community periodontal index ranges from 0 - 4 points for each tooth. Higher points mean more severe periodontitis.	Baseline; 1 year
Secondary	Major adverse cardiovascular event	The major adverse cardiovascular event includes acute myocardial infarction, stroke, heart failure, peripheral artery disease, and coronary heart disease.	Baseline; 3 months; 6 months; 9 months; 1 year; 2 years; 3 years;
Secondary	All-cause mortality	Defined as any death after enrollment.	Baseline; 3 months; 6 months; 9 months; 1 year; 2 years; 3 years;
Secondary	Change from baseline anxiety at 1 year after enrollment.	Anxiety will be assessed through "Self-Rating Anxiety Scale (SAS)". The SAS score range from 20 - 80 points. Higher points mean more serious anxiety.	Baseline; 1 year
Secondary	Change from baseline pain at 1 year after enrollment.	The degree of pain will be assessed through "Visual Analogue Scale (VAS)". The VAS score range from 0 - 10 points. Higher points mean more serious pain.	Baseline; 1 year
