Streptococcus Dentisani Colonization Capacity in a Split Mouth Model

Status Completed

Clinical Trial Summary

Pilot study with healthy subjects to test the in vivo potential colonization ability of S. dentisani. Phase I, exploratory, prospective, mechanistic pilot clinical trial with two parallel follow-up groups. Probiotic will be applied topically as an adhesive gel with a dental splint under different dosing regimes. Saliva and plaque samples will be obtained at day 0, 14 and 28.

Clinical Trial Description

Phase I study, exploratory, prospective, mechanistic, to evaluate the capacity of

Streptococcus dentisani CECT 7746 of colonizing the tooth surface. The study will be carried out with 10 healthy subjects divided into two groups (n = 5 per group) that differ in the number of applications of probiotic:

Group A: participants who will receive a single application of the product during the initial visit Group B: participants who will receive 7 applications on consecutive days, with the first in the start visit. Probiotic will be applied topically as an adhesive gel with a dental splint under different dosing regimes.The total dose received will be the same for both groups, and the total duration of the follow-up will be of 4 weeks from the first application also for both groups.

On day 0: Participants who meet the inclusion and exclusion criteria will be randomized in one of the two groups. Saliva and plaque samples will be obtained by the dentist, and all the participants will receive an professional teeth cleaning in one half of the mouth (quadrants 1-4). Afterwads, treatment will be applied by the dentist according to assigned group, and the randomized participants in the multiple-dose group will be explained how to perform the six successive applications at home every 24 hours.
