Affected dentin remineralization after partial caries excavation (in vivo): the effect of iRoot® BP Plus application

The removal of all infected dentin on deep carious lesions leads to a high risk of pulp exposure. Currently, minimally invasive treatment can be achieved by partially removing carious lesions. Partially removing the carious lesion and applying bioactive material, such as iRoot® BP Plus, can promote remineralization of the affected dentin. This study aimed to evaluate the remineralization of affected dentin by partially removing infected dentin or removing all infected dentin after the application of iRoot® BP Plus. Subjects were divided into two groups. In group I, infected dentin was partially removed, whereas in group II, all infected dentin was removed. Pixel grey value was measured in each group before and 4 weeks after the application of iRoot® BP Plus and then compared. Remineralization of the affected dentin occurred in both groups after the application of the material for 4 weeks.
