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...

This article describes a method to treat Class II malocclusions with no patient cooperation. The technique involves converting the Class II molar relationship to a Class I in the initial phase of treatment by moving the maxillary molars distally with superelastic coils and wire. Anchorage is provided by a transpalatal bar attached to the first premolars and connected to 2 palatal miniscrews. On...
