Introduction: The addition of topical CPP-ACPF and fTCP on tooth enamel can improve hardness due to remineralization process. Demineralization occur during acid environment in the oral cavity decrease. Objective: To determine effect isotonic solution immersion compare after application. Methods: Thirty six crowns maxillary first premolars were divided into three groups, each consisted 12 crowns...

The energy difference between the linear S+ and cyclic £?2 structures of G$ has been investigated using large [5s3p2dlf] basis sets and multireference electron correlation treatments, including complete active space SCF (CASSCF), multireference CI (MRCI), and averaged coupled-pair functional (ACPF) methods, as well as the single-reference quadratic configuration interaction (QCISD(T)) method. O...

ABSTRACTIntroduction Caries initiation is associated with demineralization of the toothenamel surface. Calcium and phosphorous are lost from subsurface enamel, resultingin formation a lesion. Aim: this study aimed to investigate comparethe enamel surface ultramorphology minerals content by Environmental ScanningElectron Microscope (ESEM) Energy dispersive x-ray spectroscopy (EDX) toassess micro...
