研究概览

简要总结

The objective of this clinical study is to evaluate the efficacy of multiple applications of MI Varnish in combination with MI Paste Plus in caries protection and remineralization in comparison to the use of a control (Crest 1,100ppm Fluoride tooth paste, Fluoride rinse recommendation) in orthodontic patients in a randomized, single blind, prospective, controlled clinical trial over 12 months.

The effect will be measured by white spot lesion regression and prevention as lesion count. Lesions will be scored using the Enamel Decalcification Index (EDI) area evaluation scheme (primary outcome), International Caries Detection and Assessment System (ICDAS), the caries lesion activity criteria (Nyvad criteria; Bente Nyvad, Scandinavian Researcher), and Quantitative Light Fluorescence (QLF, Inspektor Pro, Netherlands)/SOPROLIFE (SOPROLIFE fluorescence camera system, Acteon, France) evaluation in maxillary and mandibular anterior teeth with orthodontic brackets in treatment and control groups.

详细描述

The study is designed as randomized, single blind, prospective, clinical trial over 12 months. The subjects for this study will be recruited from the University of California at San Francisco UCSF, School of Dentistry, Orthodontic Clinic.

Participants in the study will be patients, who are in orthodontic treatment or will start orthodontic treatment; subjects must have full fixed appliances, with brackets bonded to the buccal surfaces of the maxillary and mandibular incisors, canines and first bicuspids. Subjects will be of moderate or high caries risk according to Caries Risk Assessment and ATP (Adenosine triphosphate) bacteria testing. Subjects will present with at least two active white spot lesions on his/her anterior teeth at the start of the study. The age limitation is ≥ 11 years.

The subjects will be randomly assigned to 1) Experimental group: MI Varnish and MI Paste Plus or 2) Control standard of care group: 1,100 ppm Fluoride tooth paste and recommendation to use OTC (Over-the-counter) Fluoride-rinse in the evening at home.

The clinical study investigator will evaluate the labial/buccal surfaces of upper and lower anterior teeth (first bicuspid to first bicuspid) for white spot lesions (WSL) at baseline and at the end of 3, 6, and 12 months. Newly formed lesions and changes in existing white spot lesions will be documented (using Enamel Decalcification Index (EDI), ICDAS II, light digital photographs and blue fluorescence photography SOPROLIFE and QLF- Quantitative Light Fluorescence).

All subjects will receive one professional tooth cleaning at baseline and at each other evaluation office visit to allow WSL evaluation (cleaning with ultrasonic device, and prophylaxis brush) and treatment application.

干预措施: CPP-ACP 5% sodium fluoride varnish & 900ppm fluoride paste (Drug)

Standard of Care

Active Comparator

Subjects will use at home regal toothpaste every night and F-mouth rinse as recommended

干预措施: 1,100pm F-toothpaste and 0.5%NaF rinse (Drug)

结局指标

主要结局

Change in White Spot Lesions Count - Enamel Decalcification Index (EDI)

时间窗: Baseline and 12-months

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.

次要结局

  • Change in International Caries Detection and Assessment System (ICDAS II) to Score for Smooth Surfaces White Spot Lesions (WSL)(Baseline and 12-months)
