Background: In patients with aggressive periodontitis, scaling and root planing is usually
combined with the use of systemic antibiotics. However, the effectiveness of these antibiotics over
time was questioned. Diode laser has been introduced as an adjunctive treatment modality in the
treatment of periodontal disease.
Objective: The aim of this study is to compare Laser debridement with non-surgical periodontal
therapy for the treatment of aggressive periodontitis.
Subjects and methods: Probing depth and clinical attachment loss were measured in six sites
for two teeth in all 10 aggressive periodontitis patients selected for the study. Also, Gingival index
was recorded.
Scaling and root planing was performed on one tooth, and the other was treated using Diode
Laser therapy. All measurements were carried at baseline and four weeks after completion of the
therapy for both modalities. Moreover, gingival samples were taken from all sites before and after
periodontal therapy.
Results: Statistically significant reduction was observed in mean gingival scores in both groups
after intervention, and the Laser group showed more statistical significance than curettage group.
However, there was no statistical significant difference between both groups concerning probing
depth measurements. Again, no significant difference was observed between groups regarding
clinical attachment loss improvement. Histopathological results showed less inflammatory infiltrate
in cases treated with Laser therapy.
Conclusion: Clinical and histopathological investigations proved that Laser therapy is more
effective in reducing inflammation in periodontitis patients. Thus, Laser application should be
adjuncted to all periodontal procedures in order to improve clinical outcomes.
