Chronic periodontitis
Conditions
Interventions
SRP group:Traditional Scaling and Root Planing (SRP) was performed on all sites with Probing Depth (PD) >= 5 mm at baseline using Gracey curettes (Hu-Friedy, USA) until the root surfaces were confirme
PE + SRP group:Periodontal endoscopy (JMD, Beijing)-assisted SRP was performed on all sites with PD >= 5 mm at baseline for enrolled patients until no visible calculus was observed endoscopically.
L + SRP group:All sites with PD >= 5 mm at baseline in enrolled patients were irradiated with an Er:YAG laser (LightWalker, Fotona, Slovenia) immediately following conventional SRP treatment.
PE + L + SRP group:For all sites with a baseline probing depth (PD) >= 5 mm in enrolled patients, endoscope-assisted scaling and root planing (SRP) was performed until no visible calculus remained end
