Résumé
OBJECTIVE@#To evaluate the effect of scaling and root planing (SRP) on serum C-reactive protein (CRP) levels in patients with moderate to severe chronic periodontitis.@*METHODS@#We searched the PubMed, Web of Science, EMBASE, Cochrane, CNKI, Wanfang, and VIP databases from the inception to July 8th, 2019. Two reviewers independently screened literature, extracted data, and evaluated the bias risk of included studies. Then, a meta-analysis was performed using RevMan 5.3 software.@*RESULTS@#A total of 13 randomized controlled clinical trials and 12 prospective clinical trials were included. Meta-analysis showed that serum CRP levels decreased at 2 and 3 months after SRP (P<0.05), and no significant difference in serum CRP levels was found at 6 months (P=0.49).@*CONCLUSIONS@#SRP can reduce serum CRP levels in systematically healthy patients with moderate to severe chronic periodontitis at 2 and 3 months after SRP.
