| Summary: | Aim:
The aim of this study was to investigate and compare the antimicrobial effects of an 810-nanometer diode laser, utilizing or not utilizing toluidine blue as a photosensitizer, in the management of peri-implant mucositis.
Settings and Design:
The present study was carried out in 30 implant sites in 15 patients with peri-implant mucositis with a specific inclusion and exclusion criteria. 15 sites were treated utilizing a diode laser (control group) and 15 with photodynamic therapy (test group) in a split-mouth format.
Materials and Methods:
Samples were taken from the gingival sulcus with the help of plastic curettes from control and test sites both at baseline and at 3 months for microbiological analysis.
Statistical Analysis Used:
Shapiro-Wilk Test was used to check deviation from normality. Wilcoxon signed-rank test was used to analyse the two dependent groups.
Results:
Intragroup comparison was found to be statistically significant when compared at baseline and at 3 months in the photodynamic (P = 0.001) and diode laser groups (P = 0.001), respectively. No statistically significant reduction in bacterial count was found at baseline (P = 0.1) and at 3 months (P = 0.5) when the diode laser group and photodynamic group were compared with each other (intergroup).
Conclusion:
Within the limitations of the study, it can be concluded that there is a definitive reduction in pathogenic bacteria with both interventions and PDT offers clinically visible benefits in the treatment of peri-implant mucositis. |
