Comparative Study Regarding the Reduction of Dental Hard Tissues Demineralization Using Different Commercial Remineralizing Products

Abstract:

The aims of this study were to investigate the surface topography and to compare the calcium and phosphorous ion concentration in enamel, dentine and cement when three different commercial remineralizing products are used after demineralization of the dental hard tissues. Twenty caries-free extracted teeth were split in two halves. A free window of enamel (E), dentine (D) and cement (C) in the cervical area of the slices was preserved. The slices were randomly divided in four groups (A-D). In control group (group A) the slices were subjected to a demineralization period of 1 hour, three times a day, 14 days. Between demineralization cycles, the samples were stored in artificial saliva. In groups B, C and D the same demineralization cycles were applied, but the first and the last demineralization period were followed by the application of Colgate Total® toothpaste (Colgate Company) for 3 min (group B), MI Paste Plus (GC Corporation) for 3 min (group C) and Home Care Fluoride gel (Alpha-Dent Company) for 1 minute (group D). The samples were analyzed using a scanning electron microscope coupled with an EDX detector. The increase of calcium and phosphorous ion concentrations was significantly higher in groups C and D when comparing to groups A and B (ANOVA and post hoc Bonferroni tests, p[ 0.05). MI Paste Plus and Home Care Fluoride gel showed a significantly higher remineralization capacity when comparing to Colgate Total® toothpaste. Keywords: enamel, dentine, cement, remineralization, EDX, SEM
