ARTICLE HIGHLIGHTS
Research background

Patients with chronic periodontitis often undergo routine treatment by supragingival cleaning and subgingival curettage, establishing a balanced occlusal relationship, and irrigation with 3% hydrogen peroxide. Treatment relieves the symptoms to some extent, but, there is room for improvement in the overall effectiveness. Er:YAG lasers quickly increase the temperature of the irradiated tissue, eliminate dental plaque and calculus, reduce periodontal pockets, adjust periodontal microecology, and reduce the gingival sulcus.

Research motivation

The study motivation was to reduce the impact of chronic periodontitis on periodontal health.

Research objectives

This study aimed to evaluate the effect of Er:YAG laser-assisted routine therapy on periodontal status in patients with chronic periodontitis.

Research methods

At our hospital, 106 patients with chronic periodontitis were randomly assigned to either a study or control group, with 53 patients in each group. The control group underwent routine therapy, and the study group underwent Er:YAG laser therapy in addition to routine therapy. The treatment outcome,, including the periodontal status, inflammatory factors in the gingival crevicular fluid, and colony forming units were evaluated in both groups.

Research results

Total effectiveness in the study group was higher than that in the control group. The clinical parameters in the study group and in the control group were not significantly before treatment. However, after treatment, the values in the study group were lower than those in the control group. There was no significant difference in crevicular TNF-α, IL-6, and IL-8 levels in the study and control groups before therapy.

Research conclusions

Combining Er:YAG lasers with routine treatment method significantly improve the overall periodontal therapy outcomes by improving the periodontal status and reducing oral levels of inflammatory factors and colony forming units.

Research perspectives

Er:YAG lasers represent a new treatment direction for periodontitis.
