Herbal drugs are commonly used in the treatment of several diseases, including periodontitis. So far, no systematic review had evaluated the evidence regarding the efficacy of these agents in the treatment of periodontal disease. Therefore, the purpose of this review was to evaluate the effect of local application of phytotherapic agents as adjuncts to scaling and root planing (SRP), compared to SRP alone, on clinical parameters of chronic periodontal patients. Only randomized controlled trials of at least 3 months follow-up, of SRP alone in association with local phytotherapic agents were included. MEDLINE (PubMed), Google Scholar and LILACS databases were searched for articles published up to October 2016. Random-effects meta-analyses were conducted for clinical attachment level and probing pocket depth (PPD) change after treatment. Of 1861 papers potentially relevant, 7 were included. All studies showed that periodontal treatment in association with local phytotherapic delivery promotes a significant PPD reduction and the majority of them showed clinical attachment level gain. The local use of phytotherapy as an adjunct to SRP may promote additional benefits in PPD reduction and clinical attachment level gain. However, these results must be interpreted with caution due to the small sample size, high risk of bias and heterogeneity of the studies.
