Abstract

OBJECTIVES:

The aim of this study was to assess the clinical effect of the administration of Lactobacillus reuteri Prodentis as a probiotic agent in the treatment of initial to moderate chronic periodontitis. Secondary objectives were to evaluate the patient 'compliance' factor and to observe the potential side-effects of the probiotic agent.

MATERIALS AND METHODS:

Twenty systemically healthy, non-smoking subjects with initial-to-moderate chronic periodontitis were enrolled in this 1-month double-blind, placebo-controlled, randomized clinical trial. Subjects were randomly assigned to receive tablets containing Lactobacillus reuteri Prodentis or placebo once a day for 30 days. Clinical parameters were collected at baseline and 30 days post-treatment.

RESULTS:

Periodontal clinical parameters were improved in the test group after a 30-day intervention. The test group demonstrated a statistically significant reduction (p < 0.05) in all the periodontal parameters included in the study (plaque index, bleeding on probing and pocket probing depths), while the control group treated with placebo did not show any statistically significant change in periodontal parameters.

CONCLUSIONS:

These data indicate that oral administration of Lactobacillus reuteri Prodentis improved the short-term clinical outcomes in non-smoking patients with initial-to-moderate chronic periodontitis.
