Progress in Orthodontics

Table 2 Elemental composition (wt%, mean values) of the enamel surfaces for the intact and treated specimens after energy-dispersive X-ray analysis (n = 5)

From: Orthodontic bonding and debonding induces structural changes but does not alter the mechanical properties of enamel
