[The micromorphology of the superficial remineralization of the dental enamel].

Abstract

The remineralization process in the oral environment is the presumption of enamel structural integrity and function. Strong or frequent acid attacks may be followed by pathological alterations. Remineralization of human enamel after phosphoric acid demineralization was investigated. 4 subjects were selected for in-vivo experiments using specialized oral applicators with 52 etched enamel specimen, incorporated for 10 or 28 days and 59 probes remineralized in a synthetic mineral solution over the same period. Mineral deposition and rehardening took place. After 28 days the reparation of acid defects was incomplete. The in-vitro remineralization is less pronounced and does not reflect the complex remineralization mechanism in vivo.
