Influence of adjunctive non-surgical peri-implant therapy on clinical and salivary cytokine profile in obese patients

Aim: The present study aimed to evaluate the impact of Photodynamic therapy (PDT) and Er,Cr:YSGG laser (ECL) adjunct to nonsurgical mechanical debridement (NSMD) in comparison to conventional NSMD in overweight individuals with peri-implant disease on peri-implant inflammatory parameters and cytokine levels of IL-6 and TNF-?? in Peri-implant crevicular fluid (PICF) Materials and Methods: Recruitment of volunteers was performed from the outpatient department according to predefined inclusion and exclusion criteria. Group 1 consisted of obese participants who underwent peri-implant mechanical debridement (MD); group 2, obese participants who experienced MD adjunct to ECL, and in group 3, obese participants were treated with MD and adjunct PDT. Clinical periodontal parameters, plaque index (PI), bleeding index (BI) and probing depth (PD) along with crestal bone loss (CBL) were assessed at baseline, 3 months, and 6 months. PICF was collected to evaluate the levels of IL-6 and TNF-??. Kruskal???Wallis and Bon-ferroni post hoc test were employed for the comparison of peri-implant inflammatory parameters and PICF cytokine profiles among the study groups. Results: Clinical peri-implant parameters (PI, BI and PD) at baseline among subjects in group 1, group 2 and group 3 were comparable (p 0.05). At 6 months follow-up, PI and BI mean scores among groups 1, 2, and 3 were comparable (p 0.05) compared to baseline with no difference noted in the control group (p 0.05). Conclusion: Photodynamic therapy and Er, Cr: YSGG adjunct to NSMD demonstrated significant improvement in peri-implant inflammatory parameters in obese individuals. Multicentric clinical trials are suggested to extrapolate the findings of the present study.

Automated summary

This study evaluated the impact of photodynamic therapy and Er, Cr:YSGG laser adjunct to nonsurgical mechanical debridement in overweight individuals with peri-implant disease. The results showed that this combined treatment significantly improved peri-implant inflammatory parameters in obese individuals.
