The aim of the study is to investigate clinical and microbiological effects of subgingival application of chloramine (Perisolv) and hyaluronic acid (Hyadent BG) gels as adjuncts to scaling and root planing in non-surgical periodontitis treatment.


  1. To evaluate if additional subgingival delivery of chloramine and hyaluronic acid gels would enhance clinical outcomes of scaling and root planing in periodontitis patients.
  2. To assess if additional subgingival delivery of chloramine and hyaluronic acid gels would reduce total counts of periodontopathogenic bacteria compared to scaling and root planing alone.

The treatment will consist of two treatment modalities: (1) Control group - full mouth scaling and root planing (SRP) (2) Test group - full mouth SRP + "Perisolv"+ Hyadent BG gels.

The periodontal treatment will be performed in one session without time restrictions. Under local anesthesia, an experienced operator, will perform a full mouth subgingival scaling and root planing with an ultrasonic device and Gracey curettes. Afterwards, all teeth will be polished using a low-abrasive paste.

Teeth in the test group (all teeth with PD 5 mm) will adjunctively be treated with chloramine gel (Perisolv), which will be inserted into periodontal pockets before and during SRP (2 times). The nozzle will be placed in the pocket mesially, lingually, distally and bucally. Teeth will be polished and all treated pockets will be filled with hyaluronic acid gel.

Teeth in control group will receive SRP + polishing
