Galofre M, et al. - Researchers estimated, clinically and microbiologically, the impact of the oral probiotic, Lactobacillus reuteri Prodentis, as adjuvant to non-surgical mechanical therapy in implants with mucositis or peri-implantitis, placed in patients with a history of periodontal disease. Over a period of at least 90 days, the clinical parameters of implants with mucositis or peri-implantitis were improved by the administration of a daily lozenge of L. reuteri for 30 days, together with mechanical debridement of the whole mouth. However, the microbiological effect was much more limited with these treatments. An alternative therapeutic approach to consider in the prevention and treatment of peri-implant diseases was provided by the probiotics.
