The effects of acid-etching on enamel from different clinical variants of amelogenesis imperfecta: an SEM study.

Purpose: Successful bonding of resins to teeth affected by amelogenesis imperfecta (AI) may be highly dependent on how the enamel responds to acid etching. The aim of this study was to determine, using scanning electron microscopy (SEM), the types of etching pattern achieved with 37% phosphoric acid on dental enamel of 5 clinical variants of AI, namely, pitted hypoplastic, smooth hypoplastic, X-linked (male), X-linked (female), and hypomineralized.

Methods: A normal premolar and primary molar from two healthy patients were used as controls.
