The Preventive Effect of 2-years Use of Hydroxyapatite Containing Toothpastes in Children.
Study Details
Study Description
Brief Summary
The aim of this RCT was to verify the caries preventive efficacy of toothpastes containing biomimetic hydroxyapatite (H.A.) complex in children compared to traditional fluoridated toothpastes. In total 610 children of two age groups (4-5 years and 6-7 years at baseline) were enrolled. Four toothpastes, two containing fluoride-substituted hydroxyapatite (H.A.F.) (1000 and 1450 ppm F-) and magnesium-, strontium-, carbonate-substituted hydroxyapatite, in a chitosan matrix and two traditional fluoridated toothpastes (1000 and 1450 ppm F-) without other active components were administered randomly to two groups with younger children (Gyoung) and to two groups with older children those containing1450 ppm F (GOLD) during 24 months. A standardized questionnaire was administered to parents/caregivers to gain information regarding caries risk factors. Caries evaluation was performed at school using ICDAS, scoring lesions as initial (up to score 2), moderate (scores 3-4) and severe (scores 5-6).

Outcome Measures
Primary Outcome Measures
- Caries Progression rate [2 year]
. Caries incidence rate was calculated on each tooth (primary and permanent) as the unit of analysis
