Diastema Closure
Before and after: click to magnify
The diastema was closed with Renamel, a composite from Cosmodent.
Why might unprepared (surface) enamel require more etching time than prepared enamel?
Surface enamel does not have a prismatic structure: it has been demineralised (by dietary acids) and remineralised (by saliva) so often that it becomes amorphous.
Extra etching time is employed by many clinicians to remove the surface layer, and expose the prismatic structure underneath: the best bond is to etched prismatic enamel.
