title: [Effect of Oravive gel on enamel remineralization and anti-demineralization of young permanent teeth treated by sugar drink].
abstract: OBJECTIVE
  To evaluate the effect of Oravive gel and fluor protectors on remineralization and the capacity of resisting sugar drink erosion.
  
  
  METHODS
  The changes of surface microhardness (SMH) of young permanent teeth treated by Oravive gel or fluor protectors which were immersed in sugar drink in advance were measured. The morphological changes of surface were observed by scanning electron microscope (SEM).
  
  
  RESULTS
  The SMH values of the young permanent teeth immersed in sugar drink and then treated with Oravive gel or fluor protectors increased significantly, and the Oravive group was stronger than fluor protectors group (P < 0.05). For the young permanent teeth treated with Oravive gel or fluor protectors and then immersed in sugar drink, the SHM value of Oravive group was significantly higher than fluor protectors group (P < 0.05). Under SEM, the enamel surface appeared solvation and remineralization after Oravive gel or fluor protectors treatment.
  
  
  CONCLUSIONS
  Oravive gel may enhance the resistance of young permanent teeth enamel to sugar drink erosion, and promote the remineralization effects of demineralized enamel.
