Clinical evaluation of topical application of perio-Q gel (Coenzyme Q(10)) in chronic periodontitis patients.

BACKGROUND AND

OBJECTIVES

Coenzyme Q(10) is a well studied antioxidant in medical literature, but studies regarding its efficacy in periodontal diseases are few. Hence, the aim of this study was to test the efficacy of coenzyme Q(10) in the form of gel (Perio-Q) in patients with chronic gingivitis and periodontitis.

MATERIALS AND

METHODS

A total of 12 patients were enrolled. A split mouth design was used for topical (extrasulcular) application, intra-pocket application alone, intra-pocket application combined with scaling and root planing (SRP) and SRP only in each quadrant, respectively. Clinical parameters such as plaque index, gingival index, gingival bleeding index, probing pocket depth, clinical attachment level were assessed at baseline, 3rd week, and 6th week. The results were subjected to statistical analysis, which were expressed as mean±SD and proportions as percentages. Intra group comparisons were made by paired t-test and one way analysis of variance (ANOVA) for inter-group comparisons. Categorical data was analyzed by Fisher's exact test.

RESULTS

The results showed on intra-group analysis significant reduction (P<0.01) of clinical parameters (plaque index (PI), gingival index (GI), gingival bleeding index (GBI), periodontal probing pocket depth (PPD), and clinical attachment level (CAL)) in all four treatment groups, whereas on inter-group analysis, intra-pocket gel application in combination with SRP showed significant reduction (P<0.05) for PI, GI, GBI, and CAL in comparison to intra-pocket gel alone.

INTERPRETATION AND

CONCLUSION

In the present study, in chronic periodontitis patients, sub-gingival mechanical debridement only and with Perio-Q gel showed almost similar clinical results without any statistically significant differences. Hence, it confirmed the primary role of basic mechanical approaches in periodontal therapy and did not provide enough clinical support for the superiority of adjunctive use of Perio-Q gel. However, it appears that Perio-Q gel in this study may have a potential additive effect. Further, long term clinical studies of Perio-Q gel with various doses and duration need to be conducted.
