The objective of this study was to evaluate the effects of lozenges-containing Lactobacillus reuteri as an adjuvant treatment of peri-implant mucositis and to detect the level of L. reuteri colonization in the peri-implant tissues of treated patients. A total of 10 patients were selected. Subjects with at least one implant affected by peri-implant mucositis, with gingival index (GI) of ⩾2 in each quadrant, evaluated at the buccal aspect of all teeth. Patients included in the study were partially edentulous and had implants with mucositis or peri-implantitis. Implants with radiographic bone loss of ⩾5 mm and/or ⩾50% of the implant length were excluded, and only one implant per patient was included. Each patient received L. reuteri-containing lozenges. Microbiological sampling was performed at baseline and on day 28 and analysed by polymerase chain reaction (PCR). Our results indicate that the use of the probiotic did not influence the peri-implant microbiota in a statistically significant way, although there was a reduction in the number of periodontal and peri-implant species. The lack of statistically significant microbiological changes could be explained either by the small sample population or by the short evaluation period. Therefore, the poor colonization of L. reuteri in the peri-implant pockets can be explained by the different anatomical and histological characteristics of the interface of the dental-gingival unit with respect to the periodontal sulcus. The administration of a daily lozenge of L. reuteri for 4 weeks had a limited effect on the microbiological analysis. Probiotics provide an alternative therapeutic approach to consider in the prevention and treatment of peri-implant diseases, but further long-term prospective studies with standardized variables are needed.
