Nevertheless, the tensile strength was sufficient to resist stress during the mini-dumbbell shape preparation as none of these restored dentin specimens was detached prior to tensile testing.
Without epoxy embedding, two cross-sectional specimens of 1 mm thickness were prepared from each restored dentin specimen using a diamond disc and low-speed handpiece.
Restoring those specimens to pristine condition was a monumental task.
In 2010, the Bath Royal Literary and Scientific Institution (BRLSI) started a project to research and restore the specimens with Bristol University.
6 Because of the bowel shrinkage occurring during the first 10 to 20 minutes after removal from the patients and additionally shrinkage after fixation, a correction factor of 12% reduction in anatomically restored (pinned) fixed specimens and 50% reduction in nonrestored fixed specimens has been proposed.
By contrast, other studies have found no significant difference in bond strength results between specimens restored immediately after bleaching or after waiting an interval period [13, 16, 17].
For the first year of the child's life, she split her working time between home, where she wrote papers and grant applications, and the university's herbarium, where she restored historical plant specimens.
This means that those with, say, a passion for crane flies will eventually be able to indulge it with the museum's 1.5m now-restored specimens.
Thereafter, the temporary restorative was removed and the specimens were restored with composite resin (Filtek Z350, 3 M Espe, Saint Paul, MN, USA).
The specimens were restored using a 3-step etch-and-rinse DBA and composite resin (CR).
