Effect of carisolv and papacárie on the resin-dentin …

In addition, caries removal with Carisolv does not produce smear layer, resulting in greater opening of the dentinal tubules, which optimizes the penetration of the adhesive systems9. Furthermore, Carisolv did not alter the mean bond strength values to dentin in the present study, which is in agreement with the findings of previous studies 16

2018-2-20 · Enamel is an acellular material formed by the intrie process of amelogenesis. Disruption caused at the initial stages of development, by means of mutations in the ENAM gene encoding the enamelin protein, results in enamel hypoplasia. Little is known about the consequence of ENAM mutation on the enamel structure at a crystallographic level.

Metallography : Wikis (The Full Wiki)

Diamond grit in suspension might start at 9 micrometres and finish at one micrometre. Generally, polishing with diamond suspension gives finer results than using silicon carbide papers (SiC papers), especially with revealing porosity, which silicon carbide paper sometimes "smear" over. After grinding the specimen, polishing is performed.
