The main question is whether the 50+ toothpaste reduces bad breath more than the standard toothpaste after 14 days of twice-daily use. The study will also assess tongue coating, dry mouth symptoms, saliva production, oral comfort, oral health-related quality of life, taste, acceptability, and unwanted effects.\n\nAbout 30 adults aged 18 to 65 years will take part. Each participant will use both toothpastes for 14 days each, in a randomly assigned order, with a 14-day break between the two treatment periods. Neither the participants nor the examiner performing the assessments will know which toothpaste is being used during each period.\n\nAt the study visits, bad breath will be measured using a device that detects volatile sulfur compounds in the mouth. Participants will also undergo an examination of the tongue, provide saliva samples, and complete questionnaires. Before each assessment visit, participants will be asked not to perform oral hygiene for 24 hours and to avoid food, drinks other than water, smoking, chewing gum, and oral care products for 3 to 4 hours.",[29,30],"Oral Malodor (Halitosis)","Oral Dryness",[32,33,34,35,36,37,38,39,40,41],"Toothpaste","Oral Malodor","Halitosis","Volatile Sulfur Compounds","Oral Comfort","Dry Mouth","Salivary Flow","Tongue Coating","Sensory Acceptability","Crossover Study","NOT_YET_RECRUITING","2026-08-18",{"date":45,"type":46},"2026-08-21","ACTUAL",{"date":48,"type":23},"2026-10-01",{"date":50,"type":23},"2026-12-15",{"name":52,"class":53},"University of Pavia","OTHER"]
