Impact of the treatment of periodontitis on systemic health and quality of life: A systematic review

Abstract

Aim: To investigate the effect of treatment of periodontitis on systemic health outcomes, pregnancy complications, and associated quality of life. Materials and methods: Systematic electronic searches were conducted to identify randomized controlled trials with minimum 6-month follow-up and reporting on the outcomes of interest. Qualitative and quantitative analyses were performed as deemed suitable. Results: Meta-analyses confirmed reductions of high-sensitivity C-reactive protein (hs-CRP) [0.56 mg/L, 95% confidence interval (CI) (−0.88, −0.25), p <37 weeks) was observed [0.77 risk ratio, 95% CI (0.60, 0.98), p =.036]. Limited evidence was reported on quality-of-life (QoL) outcomes in the included studies. Conclusions: Treatment of periodontitis results in systemic health improvements including improvement in cardiometabolic risk, reduction in systemic inflammation and the occurrence of preterm deliveries. Further research is however warranted to confirm whether these changes are sustained over time. Further, appropriate QoL outcomes should be included in the study designs of future clinical trials.
