Background: Increased oxidative stress has emerged as one of the prime factors in the pathogenesis of periodontitis. Hence, antioxidant therapy may become a promising tool in the treatment of periodontal disease. Uric acid (UA) being a major antioxidant in saliva can be used as a marker to assess the total antioxidant capacity.
Aim: The aim of the study was to investigate the influence of orally administered antioxidants (lycopene and green tea extract) on periodontal health and salivary UA levels in gingivitis patients as an adjunct to scaling and root planing (SRP).
Materials and Methods: Thirty systemically healthy participants having generalized gingivitis were randomly distributed into two groups. Control group participants received full mouth oral prophylaxis, while test group participants received oral lycopene and green tea extract (CLIK) for 45 days along with complete oral prophylaxis. Plaque index (PI), sulcular bleeding index (SBI), and salivary UA levels were evaluated at baseline and 45 days after SRP. Data were analyzed with-test, using SPSS software (PASW, Windows version 18.0).
Results: Both treatment groups demonstrated statistically highly significant (≤ 0.001) reduction in plaque and SBI. After treatment, a highly significant increase (≤ 0.001) in the test group and significant (≤ 0.05) increase in the control group was observed for salivary UA levels. Posttreatment comparison between test and control group delineated statistically significant results in PI (≤ 0.001), SBI (≤ 0.001), and salivary UA levels (≤ 0.01).
Conclusion: Lycopene with green tea extract may prove to be a promising adjunctive prophylactic and therapeutic modality in the treatment of gingivitis patients. However, further studies are needed to evaluate the additive effect of antioxidants with routine oral prophylaxis therapy.
