Aim: The aim of this study was to observe the effects of coenzyme Q10 (CoQ10) in patients with localized periodontitis and place Sticky Bone™ in defects not resolved in the test or control group. Materials and methods: A total of 30 patients with periodontitis of pocket depth ≥5 mm were randomly divided into test and control groups, each comprising 25 sites, where CoQ10 was placed in the test group and methyl cellulose in the control group; all the parameters were recorded, and patients were followed up for 12 months. At the end of 12 months, patients who did not respond to subgingival placement of CoQ10 were treated surgically where Sticky Bone™ was placed and further followed up for 6 months. Results: There was significant difference between plaque index (PI), gingival index (GI), and probing pocket depth (PPD) at baseline and 1 month, and there was an increase in values of PI and PPD seen at 6 months and significant increase in values of GI, PI, and PPD seen at 12 months, and no significant difference in values was seen at 12 months and baseline. Conclusion: Coenzyme Q10 does not aid in the treatment of periodontitis. Clinical significance: Clinically, it shows that CoQ10 has no role to play in the cases of periodontitis. In such cases, without delay patients should be taken up for periodontal flap surgery after complete scaling and root planning (SRP), if the pocket does not resolve.
