Peri-implant parameters and cytokine profile among Peri-implant disease patients treated with Er Cr YSGG laser and PDT

Aim: To assess the effect of Er,Cr:YSGG (ECL) laser-assisted non-surgical treatment and Photodynamic therapy (PDT) as an adjunct to mechanical debridement (MD) on clinical and radiographic pen-implant inflammatory parameters in patients with pen-implant disease Material and Methods: A total of 95 patients with the pen-implant disease were divided into 3 groups. Patients in group 1 were treated with MD only, patients in group 2 recieved MD+ECL and patients in group 3 were treated with MD+PDT. Perimplant parameters CBL: Crestal bone loss; PD: Probing depth; BI: Bleeding index; PI: Plaque index were measured from baseline to 3 month and 6 months follow up. The means and standard deviation (SD) of the aforementioned parameters were calculated using multiple comparison tests Post hoc Tukey test. Power analysis and sample size (PASS) was used for calculating sample size. The power was estimated at 85% along with a minimum of 30 participants in each group with a two-sided significance level of 0.05 was to be achieved Results: At baseline mean scores of pen-implant PI, BI and PD were comparable among patients in group 1 (control), 2 (ECL), and 3 (PDT). At 3 months follow up, mean scores of pen-implant PI (P <0.05), BI (P <0.05) and PD (P <0.05) in group 1 (control) were significantly higher compared to group 2 (ECL) and 3 (PDT). At 6 months follow-up, PI and BI mean scores among groups 1, 2, and 3 were comparable (P>0.05). However, PD was significantly higher in control than groups 2 and 3 (P<0.05) Conclusion: MD with adjunct ECL and adjunct PDT are more efficient in reducing pen-implant soft tissue inflammatory parameters for short-term use than MD alone.

Automated summary

Er,Cr:YSGG (ECL) laser-assisted non-surgical treatment and Photodynamic therapy (PDT) as adjuncts to mechanical debridement (MD) are more effective in reducing pen-implant soft tissue inflammatory parameters for short-term use than MD alone.
