MORALES, Alicia et al. Clinical effect of probiotic in treatment of chronic periodontitis: clinical trial. Rev. Clin. Periodoncia Implantol. Rehabil. Oral [online]. 2016, vol.9, n.2, pp.146-152. ISSN 0719-0107.

Objective The aim of this double- blind, placebo- controlled parallel- arm, randomised clinical trial was to evaluate the clinical effects of a sachet of Lactobacillus rhamnosus SP1-containing probiotic as an adjunct to non-surgical therapy. Material and method Fourty- nine subjects were screened for their elegibility to participate in this study. Twenty-eight systemically healthy volunteers with chronic periodontitis were enrolled and monitored clinically at baseline, and at 3 and 6 months after therapy. Clinical parameters measured included plaque index, bleeding on probing, pocket probing depths (PPD), and clinical attachment loss. Patients received non-surgical therapy including scaling and root planing (SRP), and were randomly assigned to a test (SRP + probiotic, n = 14) or control (SRP + placebo, n = 14) group. The administration of a sachet of Lactobacillus rhamnosus SP1 probiotic once a day for 3 months commenced after the last session of SRP. Results Both test and control groups showed improvements in clinical parameters at all time points evaluated. Furthermore, at initial visits and after 6 months follow-up, the test group showed a statistically significant reduction in percentage of sites, teeth, and number of participants with PPD ≥ 5 mm. Conclusions The results of this trial indicate that oral administration of L. rhamnosus SP1 sachets during initial therapy resulted in similar clinical improvements compared to SRP alone.
