Trial Outcomes & Findings for MI Varnish and MI Paste Plus in a Caries Prevention and Remineralization Study (NCT NCT02424097)

NCT ID: NCT02424097

Last Updated: 2020-04-22

Results Overview

The area evaluation scheme of the Enamel Decalcification Index (EDI) divides the buccal surface of each tooth into 4 quadrants and then registers the possible existence of a white spot lesion (decalcification) in each of these 4 quadrants. For each quadrant the lesion can be scaled as: 0 = no decalcification, 1 = decalcification covering \<50% of the area, 2 = decalcification covering \> 50% of the area, 3 = decalcifications covering 100% of the area or severe decalcification with cavitation. Thus, for each tooth the value can range between 0 and 12. 16 teeth per subject were evaluated, for each subject the value of each tooth was added - thus the range per one subject can be between 0 and 192. A mean over all participants in one group was calculated. A higher score means a worse outcome.

PRIMARY outcome

Timeframe: Baseline and 12-months

Population: enamel decalcification index (EDI)

The area evaluation scheme of the Enamel Decalcification Index (EDI) divides the buccal surface of each tooth into 4 quadrants and then registers the possible existence of a white spot lesion (decalcification) in each of these 4 quadrants. For each quadrant the lesion can be scaled as: 0 = no decalcification, 1 = decalcification covering \<50% of the area, 2 = decalcification covering \> 50% of the area, 3 = decalcifications covering 100% of the area or severe decalcification with cavitation. Thus, for each tooth the value can range between 0 and 12. 16 teeth per subject were evaluated, for each subject the value of each tooth was added - thus the range per one subject can be between 0 and 192. A mean over all participants in one group was calculated. A higher score means a worse outcome.

SECONDARY outcome

Timeframe: Baseline and 12-months

The International Caries Detection and Assessment System (ICDAS II) is a standardized method of caries lesion assessment.The score is based on apparent lesion severity, with scores from 0 to 6.The buccal surface of each tooth was divided into 4 quadrants, and for each quadrant a score was assigned with ICDAS scores: 0 = sound, 1 = first visual change in enamel, after air drying, 2 = distinct demineralization visual change in enamel, 3 = localized enamel breakdown due to caries with no visible dentin, 4 = surface with underlying dark shadow from dentin with or without enamel breakdown, 5 = distinct cavity with visible dentin, 6 = extensive cavity with visible dentin. The ICDAS scores were calculated as the sum of the highest ICDAS scores assigned to each examined tooth per subject. 16 teeth per subject were evaluated, thus, for each subject the value can range between 0 and 96. A mean over all participants in one group was calculated. A higher score means a worse outcome.
