Comparison of the Clinical and Microbiological Effects of CHX and HOCl Containing Mouthwashes
This study compared two mouthwashes, containing hypochlorous acid (HOCl) or chlorhexidine (CHX), for their effects on dental plaque accumulation, gum bleeding, tooth staining, and bacteria in dental plaque. Participants used each mouthwash during a separate four-day period, with a washout period between treatments. Participants also evaluated their experience with each mouthwash using a questionnaire.

Descrizione dettagliata
This single-center, randomized controlled crossover study compared mouthwashes containing 0.02% hypochlorous acid (HOCl) and 0.2% chlorhexidine (CHX) using a four-day plaque regrowth model. Thirty participants were enrolled, and 26 completed both treatment periods.
Each mouthwash was used twice daily, with 10 mL rinsed for one minute, during a four-day period. The treatment periods were separated by a 14-day washout period. Professional prophylaxis was performed at the beginning of each treatment period. Participants refrained from toothbrushing and interdental cleaning during the treatment periods.
Clinical assessments included the Modified Plaque Index, bleeding on probing, and the Modified Stain Index. Supragingival plaque samples were collected at the end of each treatment period for microbiological analysis, including bacterial colony counts and identification by MALDI-TOF mass spectrometry. Participants completed a questionnaire evaluating their experience with each mouthwash and indicated their final preference.

Modified Plaque Index
Lasso di tempo: At the end of each four-day treatment period.
|
Dental plaque was assessed using the modified Silness and Löe Plaque Index at six sites per tooth. Each site was scored from 0 (no plaque) to 3 (abundant plaque). Mean scores were calculated for the full mouth and 12 anatomical regions and compared between the HOCl and CHX treatment periods. Mean scores range from 0 to 3; higher scores indicate greater plaque accumulation. |
At the end of each four-day treatment period.

Total culturable bacterial count in supragingival plaque
Lasso di tempo: At the end of each four-day treatment period.
|
Total culturable bacterial counts were measured in supragingival plaque samples collected from molar teeth and expressed as colony-forming units per milliliter (CFU/mL). Counts were compared between the HOCl and CHX treatment periods. |
At the end of each four-day treatment period.
|
|
Bleeding on Probing (BOP)
Lasso di tempo: At the end of each four-day treatment period.
|
Bleeding was assessed at six sites per tooth using a periodontal probe. Sites showing bleeding within 30 seconds after probing were recorded as positive. BOP was calculated as the number of bleeding sites divided by the total number of examined sites, multiplied by 100. Full-mouth and regional percentages were calculated. Scores range from 0% to 100%; higher values indicate more gingival bleeding. |
At the end of each four-day treatment period.
|
|
Modified Stain Index (MSI)
Lasso di tempo: At the end of each four-day treatment period.
|
Extrinsic tooth staining was assessed in four regions on each buccal and lingual/palatal tooth surface. Intensity was scored from 0 to 3. Area was scored from 1 to 3 only when intensity was 2 or 3, using the region-specific criteria of Macpherson et al. (2000). For intensity scores of 1, the intensity × area value was defined as 1. The participant-level MSI was calculated by averaging these values across examined regions, with a range of 0-9. Higher scores indicate greater staining. |
At the end of each four-day treatment period.

Participant-reported experience with mouthwashes
Lasso di tempo: At the end of each four-day treatment period.
|
At the end of each treatment period, participants completed a five-item questionnaire assessing mouthwash taste, effects on taste perception, perceived tooth cleanliness, perceived tooth discoloration, and nausea associated with mouthwash use. Each item was rated as 1 (poor), 2 (moderate), or 3 (good). Higher scores indicate a more favorable participant rating. Each item was evaluated separately. |
At the end of each four-day treatment period.

Final mouthwash preference
Lasso di tempo: After completion of both four-day treatment periods and the intervening 14-day washout period.
|
After completing both treatment periods, participants indicated which of the two mouthwashes they preferred. The number of participants preferring each mouthwash was recorded. |
After completion of both four-day treatment periods and the intervening 14-day washout period.
