Comparative evaluation of efficacy of topical and intra-sulcular application of Co-enzyme Q10 in the non-surgical treatment of periodontal diseases.

ABSTRACT

Background: Periodontitis is a ubiquitous and irreversible inflammatory condition that affects the supporting structures of teeth, which could lead to tooth loss as well as contribute to systemic inflammation. During the inflammatory phase, there is a release of superoxide ions and reactive oxygen species, which causes an increase in the oxidative stress. To combat this stress, the use of certain antioxidants has been proposed, which will help in maintaining the harmonious equilibrium. Aim: The aim of the present systematic review is to investigate the efficacy of topical and intrasulcular application of coenzyme Q10 in nonsurgical treatment of periodontal disease. Materials and Methods: We conducted a systematic review on the clinical studies which compared the use of coenzyme Q10 as an adjunct to nonsurgical periodontal therapy. The studies mentioned in this review were in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines and met our inclusion criteria - only randomized control trials in humans and literature published between 2000 and 2020 were included. Results: Therapies with coenzyme Q10 as an adjunct to scaling and root planing (SRP) proved to show superior improvement by reduction in the clinical parameters (plaque index, gingival index, bleeding on probing, and clinical attachment loss) when compared to SRP alone. Conclusions: Adjunctive therapy with coenzyme Q10 provides longer-lasting therapeutic effects and better results when compared with SRP alone. The possibility to use the gel as a sole agent to support standard treatment procedures in periodontitis is also suggested.
