Systemic Probiotics With Mechanical Debridement associated with Synergistic Clinical Benefits in Peri-Implantitis: Study

Peri-implantitis is a biofilm-induced inflammatory disease that jeopardizes dental implant longevity and human health. As an infectious disease, its incomplete resolution with mechanical debridement alone necessitates adjunctive approaches. Systemic probiotics, within modern medicine, offer antimicrobial and immunomodulatory benefits that may enhance peri-implant health and oral wellbeing, with relevance to broader public health.

A study was done to evaluate the clinical and microbiological efficacy of systemic probiotic supplementation as an adjunct to mechanical debridement in the treatment of peri-implantitis. This prospective clinical study included 50 systemically healthy patients diagnosed with peri-implantitis. Participants were randomly assigned into two groups: Group 1 (n = 25) received mechanical debridement with placebo, while Group 2 (n = 25) received mechanical debridement combined with systemic probiotic supplementation for 30 days. Clinical parameters including Plaque Index (PI), Gingival Index (GI), probing pocket depth (PPD), clinical attachment level (CAL), and microbial load (CFU/mL) were evaluated at baseline and after one month. Both groups showed significant improvements from baseline to one month (p < 0.05); however, Group 2 demonstrated superior outcomes. At one month, Group 2 showed lower PI (0.48 ± 0.22), GI (0.52 ± 0.09), PPD (2.78 ± 0.11 mm), CAL (3.02 ± 0.07 mm), and microbial load (0.49 ± 0.02 ȕ 103 CFU/mL) compared to Group 1 (p = 0.00 for all parameters).

Systemic probiotics, when used as an adjunct to mechanical debridement, significantly improve clinical and microbiological outcomes in peri-implantitis management. This combination may offer a synergistic approach for enhanced therapeutic efficacy.
