Therapeutic Impact of Systemic Probiotics Combined with Mechanical Debridement in Peri-Implant Disease: A Clinical and Microbiological Evaluation.

Both mechanical debridement alone and mechanical debridement combined with systemic probiotics showed significant improvements in clinical parameters from baseline to one month.

• Study included 50 systemically healthy patients diagnosed with peri-implantitis, randomly assigned to two groups of 25 each.
• Group 1 (n=25) received mechanical debridement with placebo; Group 2 (n=25) received mechanical debridement combined with systemic probiotic supplementation for 30 days.
• Both groups showed significant improvements from baseline to one month (p < 0.05) across all measured clinical parameters.
• Parameters evaluated included Plaque Index (PI), Gingival Index (GI), probing pocket depth (PPD), clinical attachment level (CAL), and microbial load (CFU/mL).

Group 2 (probiotics + mechanical debridement) demonstrated superior Plaque Index and Gingival Index outcomes compared to Group 1 at one month.

• Group 2 showed PI of 0.48 ± 0.22 at one month compared to higher values in Group 1.
• Group 2 showed GI of 0.52 ± 0.09 at one month compared to higher values in Group 1.
• Differences between groups were statistically significant (p = 0.00 for all parameters).
• Probiotic supplementation was administered systemically for 30 days as an adjunct to mechanical debridement.

Group 2 demonstrated superior probing pocket depth and clinical attachment level outcomes compared to Group 1 at one month.

• Group 2 showed PPD of 2.78 ± 0.11 mm at one month.
• Group 2 showed CAL of 3.02 ± 0.07 mm at one month.
• Both PPD and CAL differences between groups were statistically significant (p = 0.00).
• These improvements were measured at one month following initiation of treatment.

Group 2 demonstrated superior microbiological outcomes with lower microbial load compared to Group 1 at one month.

• Group 2 showed a microbial load of 0.49 ± 0.02 × 10³ CFU/mL at one month.
• Microbial load difference between groups was statistically significant (p = 0.00).
• Microbial load was assessed alongside clinical parameters at baseline and after one month.
• The probiotic intervention lasted 30 days concurrent with and following mechanical debridement.

Peri-implantitis is described as showing incomplete resolution with mechanical debridement alone, necessitating adjunctive approaches.

• Peri-implantitis is characterized as a biofilm-induced inflammatory disease that jeopardizes dental implant longevity.
• The study frames mechanical debridement alone as insufficient for complete resolution of peri-implantitis.
• Systemic probiotics are noted to offer antimicrobial and immunomodulatory benefits relevant to peri-implant health.
• The study is described as a prospective clinical study with a one-month follow-up period.
