Efficacy of Two Commercially Available Chlorhexidine Mouthrinses Non-alcohol Base

Over a 72-h experimental non-brushing period, subjects abstained from all forms of mechanical oral hygiene and one group (test) used an 0.12% CHX mouthrinse with 0.05% CPC (Perioaid®), twice daily for 30 seconds and the other group (positive control) used a 0.2% CHX mouthrinse alcohol free (Corsodyl® Care), twice daily for 60 seconds. These regimens are suggested by the manufacturers in the instructions

"All subjects received a questionnaire using a visual analogue scale designed to evaluate their taste to the mouthrinse, which they had used (What is your opinion concerning the taste of the mouth rinse?). Subjects marked a point on a 10 cm long uncalibrated line with the negative extreme response (0) on the left and the positive extreme (10) at the right end. Then, they were also asked about side effects in an open answer (Did you feel any side effects caused by mouth rinse?, If so, what are they?)."
