Clinical and radiographic peri-implant outcomes with riboflavin loaded Poly-L-glycolic acid nanoparticles incorporated in aloe-vera gel treating peri-implantitis in chronic hyperglycemic patients.

Aim: The objective of the current study was to compare the effectiveness of antimicrobial photodynamic therapy (PDT) versus Poly-L-glycolic acid nanoparticles loaded riboflavin incorporated in aloe vera gel (PGA/RF/AV) on periimplant parameters and bacterial counts in chronic hyperglycemic patients having periimplantitis.

Methods: One hundred and two diabetic patients undergoing mechanical debridement (MD) were equally divided into three groups: Group 1: PGA/RF/AV+ MD, Group 2: PDT + MD, and Group 3: MD alone. Periimplant parameters [Bleeding on probing (BoP), probing depth (PD), plaque index (PI), marginal bone level (MBL)] were recorded in all three groups.
