coenzyme-q10 and Periodontitis

This systematic review focuses on the different study protocols on CoQ10 as an adjunct in non-surgical periodontitis therapy. The study protocol was developed following PRISMA guidelines and was registered in PROSPERO (CRD42021156887). A sensitive search up to January 2022 considered MEDLINE via PubMed and Web of Science, Embase, Web of Science Core Collection via Web of Science, Google Scholar, Cochrane CENTRAL, WHO (ICTRP), ClinicalTrials.gov, and grey literature. Randomized controlled (SRP with/without placebo) clinical trials (RCTs) on all types of CoQ10 administration were included. The primary outcome was probing pocket depth (PPD). Secondary outcomes were bleeding on probing, clinical attachment loss, and gingival and plaque indices. Twelve RCTs with local and five with systemic CoQ10 administration were included. The study protocols were heterogeneous. Local CoQ10 administration was performed once or several times in a period up to 15 days. Systemic CoQ10 was applied twice or three times daily for six weeks up to four months. The reporting quality was low, including missing information about CoQ10 doses. Risk of bias was high or unclear. About half of the studies reported significant group differences for PPD. Until now, no statement on the effectiveness of CoQ10 in non-surgical periodontitis therapy is possible. Further high-quality RCTs are necessary and should consider the protocol recommendations of this review.

Coenzyme Q10 gel might be beneficial for periodontitis. However, the results have been controversial. We designed a systematic review and meta-analysis to explore the efficacy of coenzyme Q10 in periodontitis patients.. A systematic review of controlled trials (PROSPERO: CRD42020212424) was performed from 1980 to August 2020 by 2 separate investigators through the following databases: Embase, CENTRAL, PubMed/MEDLINE, Scopus, Web of Science, Google Scholar, and ProQuest. Hand search of reference lists of the included studies was also performed. Of 269 records, eleven trials were included in the meta-analysis using a random-effect model.. Coenzyme Q10 could significantly reduce Plaque Index (SMD, -0.64; CI, -1.03 to -0.26, P = .002; I. Our findings encourage administration of coenzyme Q10 gel in periodontitis based on its meaningful effect on Plaque Index, Bleeding Index, gingival index, clinical attachment level and Pocket Depth. Future studies with better qualities are required for a better conclusion.

Topical application of Coenzyme Q10 (CoQ10) to the periodontal pocket was evaluated with and without subgingival mechanical debridement. Ten male patients with adult periodontitis participated and 30 periodontal pockets were selected. During the first 3 weeks, the patients did not receive any periodontal therapy except the topical application of CoQ10. After the first 3-week period, root planning and subgingival scaling were performed in all sites. CoQ10 was applied in 20 of the pockets once a week for a period of 6 weeks. Soybean oil was applied to the remaining 10 sites as a control. In the first 3-week period, significant reductions in gingival crevicular fluid flow, probing depth and attachment loss were found only at experimental sites. After mechanical subgingival debridement, significant decreases in the plaque index, gingival crevicular fluid flow, probing depth and attachment loss were found both at experimental and control sites. However, significant improvements in the modified gingival index, bleeding on probing and peptidase activity derived from periodontopathic bacteria were observed only at experimental sites. These results suggest that topical application of CoQ10 improves adult periodontitis not only as a sole treatment but also in combination with traditional nonsurgical periodontal therapy.

Periodontal diseases are worldwide chronic inflammatory conditions that are associated with heavy production of reactive oxygen species followed by damage of the tooth-supporting tissues. Although the mechanical approach of scaling and root planing (SRP) for removing of plaque is considered as the key element for controlling periodontitis, the anatomical complexity of the teeth hinders accessibility to deeper points. The aim of this study was to design a micellar nanocarrier of coenzyme Q10 (Q

To investigate the effect of coenzyme Q10 on the levels of tumor necrosis factor-α(TNF-α) and interleukin-10 (IL-10) in gingival tissue of experimental periodontitis in rats.. A total of 48 healthy Wistar rats were divided into 3 groups of 16 randomly, normal group, coenzyme Q10 treatment group (Q10 group) and periodontitis group.Normal group was fed with normal diet and water. Periodontitis models were established in other two groups.Q10 group received coenzyme Q10 for 12 weeks and periodontitis group was fed with the same dose of normal saline.Four rats in each group were sacrified before administration and 4, 8 and 12 weeks after administration. Gingival tissue samples from mandiblar first permanent molar were taken. The levels of TNF-α and IL-10 were detected by immunohistochemistry.. The expression of TNF-α in periodontitis group [54.9% (52.9%, 57.3%)] was significantly higher than that in Q10 group [15.1% (12.7%, 17.5%)] at 12 weeks (P < 0.0167) . The expression of IL-10 in periodontitis group [8.9% (7.9%, 10.0%)]was significantly lower than that in the Q10 group [38.9% (38.0%, 40.4%)] (P < 0.0167) . The expression of TNF-α in periodontitis group was significantly higher than that in Q10 group at 12th weeks (P < 0.0167) . The expression of IL-10 in periodontitis group was significantly lower than that in the Q10 group (P < 0.0167).. Coenzyme Q10 inhibits the expression of TNF-α and promotes the expression of IL-10 in periodontal tissues of experimental periodontitis rats. Coenzyme Q10 may play a role in treating periodontitis.
