In vitro Study Regarding the Effect of Various Commercial Remineralizing Products on Primary and Permanent Teeth Dentine Caries Lesions

The aims of this study research were to investigate the surface topography and to compare the remineralization potential of various commercial remineralizing products on primary and permanent teeth dentine. After artificial caries lesion formation, all the dentine samples of permanent and primary teeth were divided into five experimental groups. In group 1 (control group) the samples have been stored in distilled water. In group 2 and group 3 the dentine samples was brushed two times a day for fourteen days, using an electric toothbrush with a constant pressure and using a bean sized toothpaste for 30 s on brushing session; in group 4 on the dentine samples a water-based cream with fluoride and hydroxyapatite was applied for 5 min two times a day for fourteen days; in group 5 the dentine samples were rinsed with 20 mL antibacterial mouthwash with alcohol free natrium fluoride for 30 s two times a day for fourteen days. Between the remineralizing cycles, the samples have been stored in artificial saliva. The samples were analyzed using a scanning electron microscope and an EDX detector. In conclusion, the dentin remineralization, both in the temporary teeth and young permanent teeth, was increased, very best quality has been achieved in the study group four. The chemical analysis showed that the highest concentration of ions in dentin was represented by ions of calcium and phosphorus; the values of both ions were lower in samples dentin of temporary teeth compared to dentin of young permanent teeth samples.
