• Abstract: The primary goal of this study was to apply Lactobacillus reuteri in situ to periodontal pockets, verifying the possible gain in clinical attachment levels and reduction of periodontal pockets. This is a randomized, double-blind, split-mouth clinical study in which twelve patients were selected as sampling units to receive the treatment, at the Dental Clinic of the Potifical Catholic University of Campinas. These patients were randomized and divided into a test group (n=12) and control group (n=12). As this is a split mouth study, test and control treatment were carried out on homologous teeth from the same patient. In addition to the convencional treatment, which is scaling and root planning, the patient was also subjected to the application of a preparation containing lactobacillus reuteri in one tooth and its counterpart received a placebo. The patient didn’t know which tooth would receive the placebo and to which tooth would the lactobacillus be applied, as these were chosen by draw. Initial clinical measurements were taken by an evaluator blind to the study as well as clinical measurements after forty-five days. When observing the data, it was noticed that in the control cases the average initial measurements were 5.17mm and the final measurements were 3;83mm, therefore there was a reduction in the probing depth. The use of Lactobacillus reuteri applied in situ to reduce inflammation in the periodontal pocket and consequently, reduce probing depth and gain clinical attachment can be used as an adjunct to the already established gold standard treatment. However, there is a need for more studies to demonstrate the advantages of on-site administration.
