Study summary

Patients were instructed to use 2 different mouthwashes after performing professional tooth cleaning. The effect of each of the 2 mouthwashes was detected.

Read the detailed description

The study tests the efficacy of hyaluronic acid (HYL) mouthwash as adjunct to Chlorhexidine (CHX) mouthwash compared to Chlorhexidine mouthwash only in 16 gingivitis patients. Patients were randomly assigned to either control group received (Chlorhexidine mouthwash) or test group received (hyaluronic acid + Chlorhexidine mouthwash). Clinical parameters and patient reported outcomes as post-operative questionnaire were assessed at baseline and seven days post-operatively.
