Antibacterial Effect of Paradontax Toothpaste

Not Applicable

Completed

• Conditions: Plaque, Dental; Plaque Induced Gingivitis
• Interventions: Other: Toothpaste; Paradontax

• Registration Number: NCT05441371
• Lead Sponsor: University of Oslo

Brief Summary

The purpose of the study is to test the antibacterial effect of Parodontax toothpaste on plaque formation, and thus gingivitis compared to placebo toothpaste.

Each subject will be given 2 plastic splints that are individually adapted to their quadrant 1 and 2. In the splint in the 1st quadrant, Parodontax test toothpaste will be placed, while in the splint in the 2nd quadrant, regular toothpaste will be placed, which the subject uses daily. Each person's set of teeth is otherwise professionally cleaned.

Detailed Description

Each subject will be given 2 plastic splints that are individually adapted to their quadrant 1 and 2. In the splint in the 1st quadrant, Parodontax test toothpaste will be placed, while in the splint in the 2nd quadrant, regular toothpaste will be placed, which the subject uses daily. Each person's teeth is otherwise professionally cleaned.

Home procedure: The subject first rinses the mouth with water for 30 sec. Then both splints are placed on the teeth in the 1st quadrant and 2nd quadrant, respectively, and the rest (lower jaw) is brushed with the subject's regular toothpaste. The brace should be on for 1 min while cleaning the teeth in the lower jaw as usual, with its usual commercial toothpaste. After 1 minute, rinse your mouth with water for 30 seconds. Then the splints are removed and the mouth is immediately rinsed with water for another 30 sec. The procedure is repeated twice a day (morning and evening) for 3 weeks (21 days). In this way, the test person becomes his own control (1st quadrant versus 2nd quadrant), and the individual plaque quality is subordinate to what it would not otherwise be in a 2-group study. Furthermore, individual brushing technique will not be an issue, as we only test the antibacterial effect of the toothpaste in the splint quadrants. It is the antibacterial effect of Parodontax we test, not affected by brushing technique.

Health information that includes age, medication use, allergies, diseases, and tobacco use. Following the test period, registration of plaque (Silness\&Loe/Quigley\&Hines) and gingival bleeding (Loe\&Silness) will be registered
