Using laser and air polishing for treating gum disease

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study investigates the effectiveness of combining Er:YAG laser treatment with sub-gingival air polishing in patients with generalized stage II or III periodontitis. It employs a split-mouth design where two quadrants of the mouth are treated differently: one with the combined approach and the other with laser treatment alone. Clinical evaluations will be conducted at multiple time points over two years to assess the outcomes of both treatment methods in a Chinese population.
