Spectrophotometric Evaluation of Chlorhexidine Pigmentations After Oral Surgery: a Prospective Randomized Clinical Trial

Spectrophotometric Evaluation of Chlorhexidine Pigmentations After Periodontal Flap Surgery: a Prospective Randomized Clinical Trial

The aim of this clinical trial was to evaluate through a clinical spectrophotometric analysis the staining side effect of a 0.2% CHX mouthwash containing an anti discoloration system (ADS) compared with a 0.12% and a 0.2% CHX alone mouthwash after periodontal surgery. The efficacy of the products and the patient's opinion and acceptance were also assessed.

Inclusion Criteria:

• Good general health conditions without a medical history of medication that might interfere with periodontal tissues
• Good plaque control (FMPS ≤ 25%) and low levels of infection (FMBS ≤ 25%)
• Need for periodontal surgery

Exclusion Criteria:

• Smokers
• Allergy to CHX
• Lack of written informed consent
