Clinical Trial Summary

This study tests the remineralization of donor teeth (donorMIH) in situ in participants using 10% hydroxyapatite (HAP) toothpaste and sodium fluoride toothpaste.


Clinical Trial Description

Prior to each 2-week treatment phase, subjects will complete a 1-week washout period. Following the washout period, the intra-oral appliance containing a donorMIH tooth block will be fitted to each subject by a qualified dentist. Immediately after fitting of the first appliance (on day 1 of the first treatment phase), each subject will receive a soft bristled manual toothbrush for use throughout the duration of the study and a toothpaste according to the treatment phase. Subjects will be instructed to brush their teeth with the appliance in the mouth, two times daily, for 3 minutes on each brushing episode, in the morning after breakfast and last thing before bed, then rinsing with 10 ml of water. Over the study period, all subjects will maintain their normal dietary habits. A 7-day washout period without an appliance will follow. After completion of the second washout period, subjects will return to the clinic, and the appliance, with another MIH-bearing tooth blocks mounted, will be fitted to the subject for the phase 2 treatment period. This procedure will then be repeated until the 2-week treatment phase is completed, and each subject has gone through the two arms of the study. ;
